What is Bitcoin mining actually doing?
Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions on the blockchain and the blockchain confirms transactions to the rest of the network as having taken place.

Putting $400M of Bitcoin on your company balance sheet

Also posted on my blog as usual. Read it there if you can, there are footnotes and inlined plots.
A couple of months ago, MicroStrategy (MSTR) had a spare $400M of cash which it decided to shift to Bitcoin (BTC).
Today we'll discuss in excrutiating detail why this is not a good idea.
When a company has a pile of spare money it doesn't know what to do with, it'll normally do buybacks or start paying dividends. That gives the money back to the shareholders, and from an economic perspective the money can get better invested in other more promising companies. If you have a huge pile of of cash, you probably should be doing other things than leave it in a bank account to gather dust.
However, this statement from MicroStrategy CEO Michael Saylor exists to make it clear he's buying into BTC for all the wrong reasons:
“This is not a speculation, nor is it a hedge. This was a deliberate corporate strategy to adopt a bitcoin standard.”
Let's unpack it and jump into the economics Bitcoin:

Is Bitcoin money?

No.
Or rather BTC doesn't act as money and there's no serious future path for BTC to become a form of money. Let's go back to basics. There are 3 main economic problems money solves:
1. Medium of Exchange. Before money we had to barter, which led to the double coincidence of wants problem. When everyone accepts the same money you can buy something from someone even if they don't like the stuff you own.
As a medium of exchange, BTC is not good. There are significant transaction fees and transaction waiting times built-in to BTC and these worsen the more popular BTC get.
You can test BTC's usefulness as a medium of exchange for yourself right now: try to order a pizza or to buy a random item with BTC. How many additional hurdles do you have to go through? How many fewer options do you have than if you used a regular currency? How much overhead (time, fees) is there?
2. Unit of Account. A unit of account is what you compare the value of objects against. We denominate BTC in terms of how many USD they're worth, so BTC is a unit of account presently. We can say it's because of lack of adoption, but really it's also because the market value of BTC is so volatile.
If I buy a $1000 table today or in 2017, it's roughly a $1000 table. We can't say that a 0.4BTC table was a 0.4BTC table in 2017. We'll expand on this in the next point:
3. Store of Value. When you create economic value, you don't want to be forced to use up the value you created right away.
For instance, if I fix your washing machine and you pay me in avocados, I'd be annoyed. I'd have to consume my payment before it becomes brown, squishy and disgusting. Avocado fruit is not good money because avocadoes loses value very fast.
On the other hand, well-run currencies like the USD, GBP, CAD, EUR, etc. all lose their value at a low and most importantly fairly predictible rate. Let's look at the chart of the USD against BTC
While the dollar loses value at a predictible rate, BTC is all over the place, which is bad.
One important use money is to write loan contracts. Loans are great. They let people spend now against their future potential earnings, so they can buy houses or start businesses without first saving up for a decade. Loans are good for the economy.
If you want to sign something that says "I owe you this much for that much time" then you need to be able to roughly predict the value of the debt in at the point in time where it's due.
Otherwise you'll have a hard time pricing the risk of the loan effectively. This means that you need to charge higher interests. The risk of making a loan in BTC needs to be priced into the interest of a BTC-denominated loan, which means much higher interest rates. High interests on loans are bad, because buying houses and starting businesses are good things.

BTC has a fixed supply, so these problems are built in

Some people think that going back to a standard where our money was denominated by a stock of gold (the Gold Standard) would solve economic problems. This is nonsense.
Having control over supply of your currency is a good thing, as long as it's well run.
See here
Remember that what is desirable is low variance in the value, not the value itself. When there are wild fluctuations in value, it's hard for money to do its job well.
Since the 1970s, the USD has been a fiat money with no intrinsic value. This means we control the supply of money.
Let's look at a classic poorly drawn econ101 graph
The market price for USD is where supply meets demand. The problem with a currency based on an item whose supply is fixed is that the price will necessarily fluctuate in response to changes in demand.
Imagine, if you will, that a pandemic strikes and that the demand for currency takes a sharp drop. The US imports less, people don't buy anything anymore, etc. If you can't print money, you get deflation, which is worsens everything. On the other hand, if you can make the money printers go brrrr you can stabilize the price
Having your currency be based on a fixed supply isn't just bad because in/deflation is hard to control.
It's also a national security risk...
The story of the guy who crashed gold prices in North Africa
In the 1200s, Mansa Munsa, the emperor of the Mali, was rich and a devout Muslim and wanted everyone to know it. So he embarked on a pilgrimage to make it rain all the way to Mecca.
He in fact made it rain so hard he increased the overall supply of gold and unintentionally crashed gold prices in Cairo by 20%, wreaking an economic havoc in North Africa that lasted a decade.
This story is fun, the larger point that having your inflation be at the mercy of foreign nations is an undesirable attribute in any currency. The US likes to call some countries currency manipulators, but this problem would be serious under a gold standard.

Currencies are based on trust

Since the USD is based on nothing except the US government's word, how can we trust USD not to be mismanaged?
The answer is that you can probably trust the fed until political stooges get put in place. Currently, the US's central bank managing the USD, the Federal Reserve (the Fed for friends & family), has administrative authority. The fed can say "no" to dumb requests from the president.
People who have no idea what the fed does like to chant "audit the fed", but the fed is already one of the best audited US federal entities. The transcripts of all their meetings are out in the open. As is their balance sheet, what they plan to do and why. If the US should audit anything it's the Department of Defense which operates without any accounting at all.
It's easy to see when a central bank will go rogue: it's when political yes-men are elected to the board.
For example, before printing themselves into hyperinflation, the Venezuelan president appointed a sociologist who publicly stated “Inflation does not exist in real life” and instead is a made up capitalist lie. Note what happened mere months after his gaining control over the Venezuelan currency
This is a key policy. One paper I really like, Sargent (1984) "The end of 4 big inflations" states:
The essential measures that ended hyperinflation in each of Germany,Austria, Hungary, and Poland were, first, the creation of an independentcentral bank that was legally committed to refuse the government'sdemand or additional unsecured credit and, second, a simultaneousalteration in the fiscal policy regime.
In english: *hyperinflation stops when the central bank can say "no" to the government."
The US Fed, like other well good central banks, is run by a bunch of nerds. When it prints money, even as aggressively as it has it does so for good reasons. You can see why they started printing on March 15th as the COVID lockdowns started:
The Federal Reserve is prepared to use its full range of tools to support the flow of credit to households and businesses and thereby promote its maximum employment and price stability goals.
In english: We're going to keep printing and lowering rates until jobs are back and inflation is under control. If we print until the sun is blotted out, we'll print in the shade.

BTC is not gold

Gold is a good asset for doomsday-preppers. If society crashes, gold will still have value.
How do we know that?
Gold has held value throughout multiple historic catastrophes over thousands of years. It had value before and after the Bronze Age Collapse, the Fall of the Western Roman Empire and Gengis Khan being Gengis Khan.
Even if you erased humanity and started over, the new humans would still find gold to be economically valuable. When Europeans d̶i̶s̶c̶o̶v̶e̶r̶e̶d̶ c̶o̶n̶q̶u̶e̶r̶e̶d̶ g̶e̶n̶o̶c̶i̶d̶e̶d̶ went to America, they found gold to be an important item over there too. This is about equivalent to finding humans on Alpha-Centauri and learning that they think gold is a good store of value as well.
Some people are puzzled at this: we don't even use gold for much! But it has great properties:
First, gold is hard to fake and impossible to manufacture. This makes it good to ascertain payment.
Second, gold doesnt react to oxygen, so it doesn't rust or tarnish. So it keeps value over time unlike most other materials.
Last, gold is pretty. This might sound frivolous, and you may not like it, but jewelry has actual value to humans.
It's no coincidence if you look at a list of the wealthiest families, a large number of them trade in luxury goods.
To paraphrase Veblen humans have a profound desire to signal social status, for the same reason peacocks have unwieldy tails. Gold is a great way to achieve that.
On the other hand, BTC lacks all these attributes. Its value is largely based on common perception of value. There are a few fundamental drivers of demand:
Apart from these, it's hard to argue that BTC will retain value throughout some sort of economic catastrophe.

BTC is really risky

One last statement from Michael Saylor I take offense to is this:
“We feel pretty confident that Bitcoin is less risky than holding cash, less risky than holding gold,” MicroStrategy CEO said in an interview
"BTC is less risky than holding cash or gold long term" is nonsense. We saw before that BTC is more volatile on face value, and that as long as the Fed isn't run by spider monkeys stacked in a trench coat, the inflation is likely to be within reasonable bounds.
But on top of this, BTC has Abrupt downside risks that normal currencies don't. Let's imagine a few:

Blockchain solutions are fundamentally inefficient

Blockchain was a genius idea. I still marvel at the initial white paper which is a great mix of economics and computer science.
That said, blockchain solutions make large tradeoffs in design because they assume almost no trust between parties. This leads to intentionally wasteful designs on a massive scale.
The main problem is that all transactions have to be validated by expensive computational operations and double checked by multiple parties. This means waste:
Many design problems can be mitigated by various improvements over BTC, but it remains that a simple database always works better than a blockchain if you can trust the parties to the transaction.

A Detailed Summary of Every Single Reason Why I am Bullish on Ethereum

The following will be a list of the many reasons why I hold and am extremely bullish on ETH.

This is an extremely long post. If you just want the hopium without the detail, read the TL;DR at the bottom.

ETH 2.0

As we all know, ETH 2.0 phase 0 is right around the corner. This will lock up ETH and stakers will earn interest on their ETH in return for securing the network. Next comes phase 1 where the ETH 2 shards are introduced, shards are essentially parallel blockchains which are each responsible for a different part of Ethereum’s workload, think of it like a multi-core processor vs a single core processor. During phase 1, these shards will only act as data availability layers and won’t actually process transactions yet. However, their data can be utilised by the L2 scaling solution, rollups, increasing Ethereum’s throughput in transactions per second up to 100,000 TPS.
After phase 1 comes phase 1.5 which will move the ETH 1.0 chain into an ETH 2 shard and Ethereum will be fully secured by proof of stake. This means that ETH issuance will drop from around 5% per year to less than 1% and with EIP-1559, ETH might become a deflationary asset, but more on that later.
Finally, with ETH 2.0 phase two, each shard will be fully functional chains. With 64 of them, we can expect the base layer of Ethereum to scale around 64x, not including the massive scaling which comes from layer 2 scaling solutions like rollups as previously mentioned.
While the scaling benefits and ETH issuance reduction which comes with ETH 2.0 will be massive, they aren’t the only benefits. We also get benefits such as increased security from PoS compared to PoW, a huge energy efficiency improvement due to the removal of PoW and also the addition of eWASM which will allow contracts to be programmed in a wide range of programming languages, opening the floodgates for millions of web devs who want to be involved in Ethereum but don’t know Ethereum’s programming language, Solidity.

EIP-1559 and ETH scarcity

As I covered in a previous post of mine, ETH doesn’t have a supply cap like Bitcoin. Instead, it has a monetary policy of “minimum viable issuance”, not only is this is a good thing for network security, but with the addition of EIP-1559, it leaves the door open to the possibility of ETH issuance going negative. In short, EIP-1559 changes the fee market to make transaction prices more efficient (helping to alleviate high gas fees!) by burning a variable base fee which changes based on network usage demand rather than using a highest bidder market where miners simply include who pays them the most. This will result in most of the ETH being paid in transaction fees being burned. As of late, the amount which would be burned if EIP-1559 was in Ethereum right now would make ETH a deflationary asset!

Layer 2 Scaling

In the mean time while we are waiting for ETH 2.0, layer 2 scaling is here. Right now, projects such as Deversifi or Loopring utilise rollups to scale to thousands of tx/s on their decentralised exchange platforms or HoneySwap which uses xDai to offer a more scalable alternative to UniSwap. Speaking of which, big DeFi players like UniSwap and Synthetix are actively looking into using optimistic rollups to scale while maintaining composability between DeFi platforms. The most bullish thing about L2 scaling is all of the variety of options. Here’s a non exhaustive list of Ethereum L2 scaling solutions: - Aztec protocol (L2 scaling + privacy!) - ZKSync - Loopring - Raiden - Arbitrum Rollups - xDai - OMGNetwork - Matic - FuelLabs - Starkware - Optimism - Celer Network - + Many more

DeFi and Composability

If you’re reading this, I am sure you are aware of the phenomena which is Decentralised Finance (DeFi or more accurately, open finance). Ethereum is the first platform to offer permissionless and immutable financial services which when interacting with each other, lead to unprecedented composability and innovation in financial applications. A whole new world of possibilities are opening up thanks to this composability as it allows anyone to take existing pieces of open source code from other DeFi projects, put them together like lego pieces (hence the term money legos) and create something the world has never seen before. None of this was possible before Ethereum because typically financial services are heavily regulated and FinTech is usually proprietary software, so you don’t have any open source lego bricks to build off and you have to build everything you need from scratch. That is if what you want to do is even legal for a centralised institution!
Oh, and if you think that DeFi was just a fad and the bubble has popped, guess again! Total value locked in DeFi is currently at an all time high. Don’t believe me? Find out for yourself on the DeFi Pulse website.

NFTs and tokeniation

NFTs or “Non-Fungible Tokens” - despite the name which may confuse a layman - are a basic concept. They are unique tokens with their own unique attributes. This allows you to create digital art, human readable names for your ETH address (see ENS names and unstoppable domains), breedable virtual collectible creatures like crypto kitties, ownable in game assets like Gods Unchained cards or best of all in my opinion, tokenised ownership of real world assets which can even be split into pieces (this doesn’t necessarily require an NFT. Fungible tokens can be/are used for some of the following use cases). This could be tokenised ownership of real estate (see RealT), tokenised ownership of stocks, bonds and other financial assets (which by the way makes them tradable 24/7 and divisible unlike through the traditional system) or even tokenised ownership of the future income of a celebrity or athlete (see when NBA player Spencer Dinwiddie tokenized his own NBA contract.)

Institutional Adoption

Ethereum is by far the most widely adopted blockchain by enterprises. Ethereum’s Enterprise Ethereum Alliance (EEA) is the largest blockchain-enterprise partnership program and Ethereum is by far the most frequently leveraged blockchain for proof of concepts and innovation in the blockchain space by enterprises. Meanwhile, there are protocols like the Baseline protocol which is a shared framework which allows enterprises to use Ethereum as a common frame of reference and a base settlement layer without having to give up privacy when settling on the public Ethereum mainnet. This framework makes adopting Ethereum much easier for other enterprises.

Institutional Investment

One of Bitcoin’s biggest things it has going for it right now is the growing institutional investment. In case you were wondering, Ethereum has this too! Grayscale offers investment in the cryptocurrency space for financial institutions and their Ethereum fund has already locked up more than 2% of the total supply of ETH. Not only this, but as businesses transact on Ethereum and better understand it, not only will they buy up ETH to pay for their transactions, but they will also realise that much like Bitcoin, Ethereum is a scarce asset. Better yet, a scarce asset which offers yield. As a result, I expect to see companies having ETH holdings become the norm just like how Bitcoin is becoming more widespread on companies’ balance sheets.

The state of global markets

With asset prices in almost every asset class at or near all-time highs and interest rates lower than ever and even negative in some cases, there really aren’t many good opportunities in the traditional financial system right now. Enter crypto - clearly the next evolution of financial services (as I explained in the section on DeFi earlier in this post), with scarce assets built in at the protocol layer, buying BTC or ETH is a lot like buying shares in TCP/IP in 1990 (that is if the underlying protocols of the internet could be invested in which they couldn’t). Best of all, major cryptos are down from their all-time highs anywhere between 35% for BTC or 70% for ETH and much more for many altcoins. This means that they can significantly appreciate in value before entering uncharted, speculative bubble territory.
While of course we could fall dramatically at any moment in the current macro financial conditions, as a longer term play, crypto is very alluring. The existing financial system has shown that it is in dire need of replacing and the potential replacement has started rearing its head in the form of crypto and DeFi.

Improvements in user onboarding and abstracting away complexity

Ethereum has started making huge leaps forward in terms of usability for the end user. We now have ENS names and unstoppable domains which allow you to send ETH to yournamehere.ETH or TrickyTroll.crypto (I don’t actually have that domain, that’s just an example). No longer do you have to check every character of your ugly hexadecimal 0x43AB96D… ETH address to ensure you’re sending your ETH to the right person. We also have smart contract wallets like Argent wallet or the Gnosis safe. These allow for users to access their wallets and interact with DeFi self-custodially from an app on their phone without having to record a private key or recovery phrase. Instead, they offer social recovery and their UI is straight forward enough for anyone who uses a smart phone to understand. Finally, for the more experienced users, DApps like Uniswap have pretty, super easy to use graphical user interfaces and can be used by anyone who knows how to run and use a browser extension like Metamask.

The lack of an obvious #1 ETH killer

One of Ethereum’s biggest threats is for it to be overthrown by a so-called “Ethereum killer” blockchain which claims to do everything Ethereum can do and sometimes more. While there are competitors which are each formidable to a certain extent such as Polkadot, Cardano and EOS, each have their own weaknesses. For example, Polkadot and Cardano are not fully operational yet and EOS is much more centralised than Ethereum. As a result, none of these competitors have any significant network effects just yet relative to the behemoth which is Ethereum. This doesn’t mean that these projects aren’t a threat. In fact, I am sure that projects like Polkadot (which is more focused on complimenting Ethereum than killing it) will take a slice out of Ethereum’s pie. However, I am still very confident that Ethereum will remain on top due to the lack of a clear number 2 smart contract platform. Since none of these ETH killers stands out as the second place smart contract platform, it makes it much harder for one project to create a network effect which even begins to threaten Ethereum’s dominance. This leads me onto my next reason - network effects.

Network effects

This is another topic which I made a previous post on. The network effect is why Bitcoin is still the number one cryptocurrency and by such a long way. Bitcoin is not the most technologically advanced cryptocurrency. However, it has the most widespread name recognition and the most adoption in most metrics (ETH beats in in some metrics these days). The network effect is also why most people use Zoom and Facebook messengeWhatsApp despite the existence of free, private, end to end encrypted alternatives which have all the same features (Jitsi for the zoom alternative and Signal for the private messenger app. I highly recommend both. Let’s get their network effects going!). It is the same for Bitcoin. People don’t want to have to learn about or set up a wallet for alternative options. People like what is familiar and what other people use. Nobody wants to be “that guy” who makes you download yet another app and account you have to remember the password/private key for. In the same way, Enterprises don’t want to have to create a bridge between their existing systems and a dozen different blockchains. Developers don’t want to have to create DeFi money legos from scratch on a new chain if they can just plug in to existing services like Uniswap. Likewise, users don’t want to have to download another browser extension to use DApps on another chain if they already use Ethereum. I know personally I have refrained from investing in altcoins because I would have to install another app on my hardware wallet or remember another recovery phrase.
Overthrowing Ethereum’s network effect is one hell of a big task these days. Time is running out for the ETH killers.

Ethereum is the most decentralised and provably neutral smart contract platform

Ethereum is also arguably the most decentralised and provably neutral smart contract platform (except for maybe Ethereum Classic on the neutrality part). Unlike some smart contract platforms, you can’t round up everyone at the Ethereum Foundation or any select group of people and expect to be able to stop the network. Not only this, but the Ethereum foundation doesn’t have the ability to print more ETH or push through changes as they wish like some people would lead you on to believe. The community would reject detrimental EIPs and hard fork. Ever since the DAO hack, the Ethereum community has made it clear that it will not accept EIPs which attempt to roll back the chain even to recover hacked funds (see EIP-999).
Even if governments around the world wanted to censor the Ethereum blockchain, under ETH 2.0’s proof of stake, it would be incredibly costly and would require a double digit percentage of the total ETH supply, much of which would be slashed (meaning they would lose it) as punishment for running dishonest validator nodes. This means that unlike with proof of work where a 51% attacker can keep attacking the network, under proof of stake, an attacker can only perform the attack a couple of times before they lose all of their ETH. This makes attacks much less financially viable than it is on proof of work chains. Network security is much more than what I laid out above and I am far from an expert but the improved resistance to 51% attacks which PoS provides is significant.
Finally, with the US dollar looking like it will lose its reserve currency status and the existing wire transfer system being outdated, superpowers like China won’t want to use US systems and the US won’t want to use a Chinese system. Enter Ethereum, the provably neutral settlement layer where the USA and China don’t have to trust each other or each other’s banks because they can trust Ethereum. While it may sound like a long shot, it does make sense if Ethereum hits a multi-trillion dollar market cap that it is the most secure and neutral way to transfer value between these adversaries. Not to mention if much of the world’s commerce were to be settled in the same place - on Ethereum - then it would make sense for governments to settle on the same platform.

ETH distribution is decentralised

Thanks to over 5 years of proof of work - a system where miners have to sell newly minted ETH to pay for electricity costs - newly mined ETH has found its way into the hands of everyday people who buy ETH off miners selling on exchnages. As pointed out by u/AdamSC1 in his analysis of the top 10K ETH addresses (I highly recommend reading this if you haven’t already), the distribution of ETH is actually slightly more decentralised than Bitcoin with the top 10,000 ETH wallets holding 56.70% of ETH supply compared to the top 10,000 Bitcoin wallets which hold 57.44% of the Bitcoin supply. This decentralised distribution means that the introduction of staking won’t centralise ETH in the hands of a few wallets who could then control the network. This is an advantage for ETH which many proof of stake ETH killers will never have as they never used PoW to distribute funds widely throughout the community and these ETH killers often did funding rounds giving large numbers of tokens to VC investors.

The community

Finally, while I may be biased, I think that Ethereum has the friendliest community. Anecdotally, I find that the Ethereum developer community is full of forward thinking people who want to make the world a better place and build a better future, many of whom are altruistic and don’t always act in their best interests. Compare this to the much more conservative, “at least we’re safe while the world burns” attitude which many Bitcoiners have. I don’t want to generalise too much here as the Bitcoin community is great too and there are some wonderful people there. But the difference is clear if you compare the daily discussion of Bitcoin to the incredibly helpful and welcoming daily discussion of EthFinance who will happily answer your noob questions without calling you an idiot and telling you to do you own research (there are plenty more examples in any of the daily threads). Or the very helpful folks over at EthStaker who will go out of their way to help you set up an ETH 2.0 staking node on the testnets (Shoutout to u/superphiz who does a lot of work over in that sub!). Don’t believe me? Head over to those subs and see for yourself.
Please don’t hate on me if you disagree about which project has the best community, it is just my very biased personal opinion and I respect your opinion if you disagree! :)

TL;DR:

FYI: yesterday I got trolled by someone using a password from a hacked account, and fishing for a payout. The password was a simple one I used on a few old accounts. It was really a blessing, because it finally motivated me to set up 1Password, and start migrating my 400+ accts/logins to it.

In case any user has a related question, you'll know why... The subject of the email was my old password. Here's the body:
I know [xxxx] is one of your password on day of hack.
Lets get directly to the point.
Not one person has paid me to check about you.
You do not know me and you're probably thinking why you are getting this email?
in fact, i actually placed a malware on the adult vids (adult porn) website and you know what, you visited this site to experience fun (you know what i mean).
When you were viewing videos, your browser started out operating as a RDP having a key logger which provided me with accessibility to your display and web cam.
immediately after that, my malware obtained every one of your contacts from your Messenger, FB, as well as email account.
after that i created a double-screen video. 1st part shows the video you were viewing (you have a nice taste omg), and 2nd part displays the recording of your cam, and its you.
Best solution would be to pay me $1007.
We are going to refer to it as a donation. in this situation, i most certainly will without delay remove your video.
My -BTC -address: [wishful thinking]
[case SeNSiTiVe, copy & paste it]
You could go on your life like this never happened and you will not ever hear back again from me.
You'll make the payment via Bitcoin (if you do not know this, search 'how to buy bitcoin' in Google).
if you are planning on going to the law, surely, this e-mail can not be traced back to me, because it's hacked too.
I have taken care of my actions. i am not looking to ask you for a lot, i simply want to be paid.
if i do not receive the bitcoin;, i definitely will send out your video recording to all of your contacts including friends and family, co-workers, and so on.
Nevertheless, if i do get paid, i will destroy the recording immediately.
If you need proof, reply with Yeah then i will send out your video recording to your 8 friends.
it's a nonnegotiable offer and thus please don't waste mine time & yours by replying to this message.

EIP-1559 and ETH scarcity

As I covered in a previous post of mine, ETH doesn’t have a supply cap like Bitcoin. Instead, it has a monetary policy of “minimum viable issuance”, not only is this is a good thing for network security, but with the addition of EIP-1559, it leaves the door open to the possibility of ETH issuance going negative. In short, EIP-1559 changes the fee market to make transaction prices more efficient (helping to alleviate high gas fees!) by burning a variable base fee which changes based on network usage demand rather than using a highest bidder market where miners simply include who pays them the most. This will result in most of the ETH being paid in transaction fees being burned. As of late, the amount which would be burned if EIP-1559 was in Ethereum right now would make ETH a deflationary asset!

Layer 2 Scaling

In the mean time while we are waiting for ETH 2.0, layer 2 scaling is here. Right now, projects such as Deversifi or Loopring utilise rollups to scale to thousands of tx/s on their decentralised exchange platforms or HoneySwap which uses xDai to offer a more scalable alternative to UniSwap. Speaking of which, big DeFi players like UniSwap and Synthetix are actively looking into using optimistic rollups to scale while maintaining composability between DeFi platforms. The most bullish thing about L2 scaling is all of the variety of options. Here’s a non exhaustive list of Ethereum L2 scaling solutions: - Aztec protocol (L2 scaling + privacy!) - ZKSync - Loopring - Raiden - Arbitrum Rollups - xDai - OMGNetwork - Matic - FuelLabs - Starkware - Optimism - Celer Network - + Many more

DeFi and Composability

If you’re reading this, I am sure you are aware of the phenomena which is Decentralised Finance (DeFi or more accurately, open finance). Ethereum is the first platform to offer permissionless and immutable financial services which when interacting with each other, lead to unprecedented composability and innovation in financial applications. A whole new world of possibilities are opening up thanks to this composability as it allows anyone to take existing pieces of open source code from other DeFi projects, put them together like lego pieces (hence the term money legos) and create something the world has never seen before. None of this was possible before Ethereum because typically financial services are heavily regulated and FinTech is usually proprietary software, so you don’t have any open source lego bricks to build off and you have to build everything you need from scratch. That is if what you want to do is even legal for a centralised institution!
Oh, and if you think that DeFi was just a fad and the bubble has popped, guess again! Total value locked in DeFi is currently at an all time high. Don’t believe me? Find out for yourself at: https://defipulse.com

NFTs and tokeniation

NFTs or “Non-Fungible Tokens” - despite the name which may confuse a layman - are a basic concept. They are unique tokens with their own unique attributes. This allows you to create digital art, human readable names for your ETH address (see ENS names and unstoppable domains), breedable virtual collectible creatures like crypto kitties, ownable in game assets like Gods Unchained cards or best of all in my opinion, tokenised ownership of real world assets which can even be split into pieces (this doesn’t necessarily require an NFT. Fungible tokens can be/are used for some of the following use cases). This could be tokenised ownership of real estate (see RealT), tokenised ownership of stocks, bonds and other financial assets (which by the way makes them tradable 24/7 and divisible unlike through the traditional system) or even tokenised ownership of the future income of a celebrity or athlete (see when NBA Star Spencer Dinwiddie Tokenized His Own NBA Contract.

Institutional Adoption

Ethereum is by far the most widely adopted blockchain by enterprises. Ethereum’s Enterprise Ethereum Alliance (EEA) is the largest blockchain-enterprise partnership program and Ethereum is by far the most frequently leveraged blockchain for proof of concepts and innovation in the blockchain space by enterprises. Meanwhile, there are protocols like the Baseline protocol which is a shared framework which allows enterprises to use Ethereum as a common frame of reference and a base settlement layer without having to give up privacy when settling on the public Ethereum mainnet. This framework makes adopting Ethereum much easier for other enterprises.

Institutional Investment

One of Bitcoin’s biggest things it has going for it right now is the growing institutional investment. In case you were wondering, Ethereum has this too! Grayscale offers investment in the cryptocurrency space for financial institutions and their Ethereum fund has already locked up more than 2% of the total supply of ETH. Not only this, but as businesses transact on Ethereum and better understand it, not only will they buy up ETH to pay for their transactions, but they will also realise that much like Bitcoin, Ethereum is a scarce asset. Better yet, a scarce asset which offers yield. As a result, I expect to see companies having ETH holdings become the norm just like how Bitcoin is becoming more widespread on companies’ balance sheets.

The state of global markets

With asset prices in almost every asset class at or near all-time highs and interest rates lower than ever and even negative in some cases, there really aren’t many good opportunities in the traditional financial system right now. Enter crypto - clearly the next evolution of financial services (as I explained in the section on DeFi earlier in this post), with scarce assets built in at the protocol layer, buying BTC or ETH is a lot like buying shares in TCP/IP in 1990 (that is if the underlying protocols of the internet could be invested in which they couldn’t). Best of all, major cryptos are down from their all-time highs anywhere between 35% for BTC or 70% for ETH and much more for many altcoins. This means that they can significantly appreciate in value before entering uncharted, speculative bubble territory.
While of course we could fall dramatically at any moment in the current macro financial conditions, as a longer term play, crypto is very alluring. The existing financial system has shown that it is in dire need of replacing and the potential replacement has started rearing its head in the form of crypto and DeFi.

Improvements in user onboarding and abstracting away complexity

Ethereum has started making huge leaps forward in terms of usability for the end user. We now have ENS names and unstoppable domains which allow you to send ETH to yournamehere.ETH or TrickyTroll.crypto (I don’t actually have that domain, that’s just an example). No longer do you have to check every character of your ugly hexadecimal 0x43AB96D… ETH address to ensure you’re sending your ETH to the right person. We also have smart contract wallets like Argent wallet or the Gnosis safe. These allow for users to access their wallets and interact with DeFi self-custodially from an app on their phone without having to record a private key or recovery phrase. Instead, they offer social recovery and their UI is straight forward enough for anyone who uses a smart phone to understand. Finally, for the more experienced users, DApps like Uniswap have pretty, super easy to use graphical user interfaces and can be used by anyone who knows how to run and use a browser extension like Metamask.

The lack of an obvious #1 ETH killer

One of Ethereum’s biggest threats is for it to be overthrown by a so-called “Ethereum killer” blockchain which claims to do everything Ethereum can do and sometimes more. While there are competitors which are each formidable to a certain extent such as Polkadot, Cardano and EOS, each have their own weaknesses. For example, Polkadot and Cardano are not fully operational yet and EOS is much more centralised than Ethereum. As a result, none of these competitors have any significant network effects just yet relative to the behemoth which is Ethereum. This doesn’t mean that these projects aren’t a threat. In fact, I am sure that projects like Polkadot (which is more focused on complimenting Ethereum than killing it) will take a slice out of Ethereum’s pie. However, I am still very confident that Ethereum will remain on top due to the lack of a clear number 2 smart contract platform. Since none of these ETH killers stands out as the second place smart contract platform, it makes it much harder for one project to create a network effect which even begins to threaten Ethereum’s dominance. This leads me onto my next reason - network effects.

Network effects

This is another topic which I made a previous post on. The network effect is why Bitcoin is still the number one cryptocurrency and by such a long way. Bitcoin is not the most technologically advanced cryptocurrency. However, it has the most widespread name recognition and the most adoption in most metrics (ETH beats in in some metrics these days). The network effect is also why most people use Zoom and Facebook messengeWhatsApp despite the existence of free, private, end to end encrypted alternatives which have all the same features (https://meet.jit.si/ for zoom alternative and Signal for the private messenger app. I highly recommend both. Let’s get their network effects going!). It is the same for Bitcoin. People don’t want to have to learn about or set up a wallet for alternative options. People like what is familiar and what other people use. Nobody wants to be “that guy” who makes you download yet another app and account you have to remember the password/private key for. In the same way, Enterprises don’t want to have to create a bridge between their existing systems and a dozen different blockchains. Developers don’t want to have to create DeFi money legos from scratch on a new chain if they can just plug in to existing services like Uniswap. Likewise, users don’t want to have to download another browser extension to use DApps on another chain if they already use Ethereum. I know personally I have refrained from investing in altcoins because I would have to install another app on my hardware wallet or remember another recovery phrase.
Overthrowing Ethereum’s network effect is one hell of a big task these days. Time is running out for the ETH killers.

Ethereum is the most decentralised and provably neutral smart contract platform

Ethereum is also arguably the most decentralised and provably neutral smart contract platform (except for maybe Ethereum Classic on the neutrality part). Unlike some smart contract platforms, you can’t round up everyone at the Ethereum Foundation or any select group of people and expect to be able to stop the network. Not only this, but the Ethereum foundation doesn’t have the ability to print more ETH or push through changes as they wish like some people would lead you on to believe. The community would reject detrimental EIPs and hard fork. Ever since the DAO hack, the Ethereum community has made it clear that it will not accept EIPs which attempt to roll back the chain even to recover hacked funds (see EIP-999).
Even if governments around the world wanted to censor the Ethereum blockchain, under ETH 2.0’s proof of stake, it would be incredibly costly and would require a double digit percentage of the total ETH supply, much of which would be slashed (meaning they would lose it) as punishment for running dishonest validator nodes. This means that unlike with proof of work where a 51% attacker can keep attacking the network, under proof of stake, an attacker can only perform the attack a couple of times before they lose all of their ETH. This makes attacks much less financially viable than it is on proof of work chains. Network security is much more than what I laid out above and I am far from an expert but the improved resistance to 51% attacks which PoS provides is significant.
Finally, with the US dollar looking like it will lose its reserve currency status and the existing wire transfer system being outdated, superpowers like China won’t want to use US systems and the US won’t want to use a Chinese system. Enter Ethereum, the provably neutral settlement layer where the USA and China don’t have to trust each other or each other’s banks because they can trust Ethereum. While it may sound like a long shot, it does make sense if Ethereum hits a multi-trillion dollar market cap that it is the most secure and neutral way to transfer value between these adversaries. Not to mention if much of the world’s commerce were to be settled in the same place - on Ethereum - then it would make sense for governments to settle on the same platform.

ETH distribution is decentralised

Thanks to over 5 years of proof of work - a system where miners have to sell newly minted ETH to pay for electricity costs - newly mined ETH has found its way into the hands of everyday people who buy ETH off miners selling on exchnages. As pointed out by u/AdamSC1 in his analysis of the top 10K ETH addresses (I highly recommend reading this if you haven’t already), the distribution of ETH is actually slightly more decentralised than Bitcoin with the top 10,000 ETH wallets holding 56.70% of ETH supply compared to the top 10,000 Bitcoin wallets which hold 57.44% of the Bitcoin supply. This decentralised distribution means that the introduction of staking won’t centralise ETH in the hands of a few wallets who could then control the network. This is an advantage for ETH which many proof of stake ETH killers will never have as they never used PoW to distribute funds widely throughout the community and these ETH killers often did funding rounds giving large numbers of tokens to VC investors.

The community

Finally, while I may be biased, I think that Ethereum has the friendliest community. Anecdotally, I find that the Ethereum developer community is full of forward thinking people who want to make the world a better place and build a better future, many of whom are altruistic and don’t always act in their best interests. Compare this to the much more conservative, “at least we’re safe while the world burns” attitude which many Bitcoiners have. I don’t want to generalise too much here as the Bitcoin community is great too and there are some wonderful people there. But the difference is clear if you compare the daily discussion of Bitcoin to the incredibly helpful and welcoming daily discussion of EthFinance who will happily answer your noob questions without calling you an idiot and telling you to do you own research (there are plenty more examples in any of the daily threads). Or the very helpful folks over at EthStaker who will go out of their way to help you set up an ETH 2.0 staking node on the testnets (Shoutout to u/superphiz who does a lot of work over in that sub!). Don’t believe me? Head over to those subs and see for yourself.
Please don’t hate on me if you disagree about which project has the best community, it is just my very biased personal opinion and I respect your opinion if you disagree! :)

Beautiful start and the tedious grind

So Ive been playing the game for a little over a month now. My initial impression was, "finally the gacha game Ive been looking for." It is actually a game instead of a character manager with auto everything. The story has been great and it has been fun exploring new areas. I completed part 1 and Im now working on Ogre wars 1. However, as great as the game has been so far, there is one thing that Im struggling to do, the dungeon grind. My characters are good enough that I can complete the dungeons, but not good enough that I can just auto attack my way through everything. So Im literally repeating the same abilities in the same order, over and over and over and over. Im starting to feel like Im manually mining bitcoin for Wright Flyer Studios and GREE. It's not challenging, and it is not fun. Im honestly at the point where I cant use my dungeon keys everyday because I cannot bare going back into the same %#@^@ dungeons and doing the same key presses over and over and over. For example I lucked into Myunfa (game over easy mode) as my first 5*. So my combat is switch to Myunfa, cast all my earth spells, listen to Myunfa say the same thing she says every damn time I switch to her, watch the banner tell me the earth zone is active, then finally put a gun in my mouth cause I have to watch this 30 times every dungeon. When Im playing through the story content there is breaks and pauses so I can forget the combat grind, but in dungeons its tea kettle comments and pain. Anyway, Im starting to find out that this is pretty much what the game is if I want to continue to improve my characters.
So my first question, am I missing something? Is there a way to achieve the grind materials without running the same dungeons over and over?
Also is there some way I can get Tsubura gems without running VH dungeons over and over? At least with Tsubura gems I can make some character improvements over time. Like for example it would be absolutely amazing if I could trade in my dungeon keys for Tsubura gems. When I first saw the Tsubura gem merchant, my first thought was thank god, I can trade my keys for gems and not have to run dungeons!! Here take my keys and give me 5 gems a pop, anything to skip running dungeons all night. But no, its the other way around!!! I can only trade gems for more keys!! We are mining bitcoin for this company, Im almost positive. Anyway, jokes aside, that was my qol idea. Trade keys for gems.
Any input on how I can streamline this process would be great. I was looking through the subreddit, but I cant find anything that speeds up combat other than the repeat button. Appreciate any tips or tricks people may have.
*Edit 9/3/2020*
So after reading a lot of the responses, a common response is, focus on something else (netflix, podcast, pron, etc.). A completely valid response, and a good idea if you want to grind (especially since there does not appear to be any other method and all you can do is improve your party and therefore your clear speed). And this response (focus on something else) seems to also come from people who genuinely enjoy the grind and the game as well. But I can't help but point out that I think this is also strong criticism towards the dungeon grind end game. Given how long this game has been out, I am a bit surprised that the developers haven't come up with some new ideas that maybe preserve some of the time commitment but also make the process fun. Like I said above, Im new to this game, and it did not take me long to experience the tedium. Anyway, I appreciate the ideas posted below, and for now it looks like I will just have to find a way to make the grind process faster through better characters and combinations of characters. Cause I can deal with a couple cups a tea a day, but by god I cant do 30 an hour. #Myunfawillwaterboardyouwithtea

Why Osana takes so long? (Programmer's point of view on current situation)

I decided to write a comment about «Why Osana takes so long?» somewhere and what can be done to shorten this time. It turned into a long essay. Here's TL;DR of it:
The cost of never paying down this technical debt is clear; eventually the cost to deliver functionality will become so slow that it is easy for a well-designed competitive software product to overtake the badly-designed software in terms of features. In my experience, badly designed software can also lead to a more stressed engineering workforce, in turn leading higher staff churn (which in turn affects costs and productivity when delivering features). Additionally, due to the complexity in a given codebase, the ability to accurately estimate work will also disappear.
Junade Ali, Mastering PHP Design Patterns (2016)
Longer version: I am not sure if people here wanted an explanation from a real developer who works with C and with relatively large projects, but I am going to do it nonetheless. I am not much interested in Yandere Simulator nor in this genre in general, but this particular development has a lot to learn from for any fellow programmers and software engineers to ensure that they'll never end up in Alex's situation, especially considering that he is definitely not the first one to got himself knee-deep in the development hell (do you remember Star Citizen?) and he is definitely not the last one.
On the one hand, people see that Alex works incredibly slowly, equivalent of, like, one hour per day, comparing it with, say, Papers, Please, the game that was developed in nine months from start to finish by one guy. On the other hand, Alex himself most likely thinks that he works until complete exhaustion each day. In fact, I highly suspect that both those sentences are correct! Because of the mistakes made during early development stages, which are highly unlikely to be fixed due to the pressure put on the developer right now and due to his overall approach to coding, cost to add any relatively large feature (e.g. Osana) can be pretty much comparable to the cost of creating a fan game from start to finish. Trust me, I've seen his leaked source code (don't tell anybody about that) and I know what I am talking about. The largest problem in Yandere Simulator right now is its super slow development. So, without further ado, let's talk about how «implementing the low hanging fruit» crippled the development and, more importantly, what would have been an ideal course of action from my point of view to get out. I'll try to explain things in the easiest terms possible.
  1. else if's and lack any sort of refactoring in general
The most «memey» one. I won't talk about the performance though (switch statement is not better in terms of performance, it is a myth. If compiler detects some code that can be turned into a jump table, for example, it will do it, no matter if it is a chain of if's or a switch statement. Compilers nowadays are way smarter than one might think). Just take a look here. I know that it's his older JavaScript code, but, believe it or not, this piece is still present in C# version relatively untouched.
I refactored this code for you using C language (mixed with C++ since there's no this pointer in pure C). Take a note that else if's are still there, else if's are not the problem by itself.
The refactored code is just objectively better for one simple reason: it is shorter, while not being obscure, and now it should be able to handle, say, Trespassing and Blood case without any input from the developer due to the usage of flags. Basically, the shorter your code, the more you can see on screen without spreading your attention too much. As a rule of thumb, the less lines there are, the easier it is for you to work with the code. Just don't overkill that, unless you are going to participate in International Obfuscated C Code Contest. Let me reiterate:
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.
Antoine de Saint-Exupéry
This is why refactoring — activity of rewriting your old code so it does the same thing, but does it quicker, in a more generic way, in less lines or simpler — is so powerful. In my experience, you can only keep one module/class/whatever in your brain if it does not exceed ~1000 lines, maybe ~1500. Splitting 17000-line-long class into smaller classes probably won't improve performance at all, but it will make working with parts of this class way easier.
Is it too late now to start refactoring? Of course NO: better late than never.
  1. Comments
If you think that you wrote this code, so you'll always easily remember it, I have some bad news for you: you won't. In my experience, one week and that's it. That's why comments are so crucial. It is not necessary to put a ton of comments everywhere, but just a general idea will help you out in the future. Even if you think that It Just Works™ and you'll never ever need to fix it. Time spent to write and debug one line of code almost always exceeds time to write one comment in large-scale projects. Moreover, the best code is the code that is self-evident. In the example above, what the hell does (float) 6 mean? Why not wrap it around into the constant with a good, self-descriptive name? Again, it won't affect performance, since C# compiler is smart enough to silently remove this constant from the real code and place its value into the method invocation directly. Such constants are here for you.
I rewrote my code above a little bit to illustrate this. With those comments, you don't have to remember your code at all, since its functionality is outlined in two tiny lines of comments above it. Moreover, even a person with zero knowledge in programming will figure out the purpose of this code. It took me less than half a minute to write those comments, but it'll probably save me quite a lot of time of figuring out «what was I thinking back then» one day.
Is it too late now to start adding comments? Again, of course NO. Don't be lazy and redirect all your typing from «debunk» page (which pretty much does the opposite of debunking, but who am I to judge you here?) into some useful comments.
  1. Unit testing
This is often neglected, but consider the following. You wrote some code, you ran your game, you saw a new bug. Was it introduced right now? Is it a problem in your older code which has shown up just because you have never actually used it until now? Where should you search for it? You have no idea, and you have one painful debugging session ahead. Just imagine how easier it would be if you've had some routines which automatically execute after each build and check that environment is still sane and nothing broke on a fundamental level. This is called unit testing, and yes, unit tests won't be able to catch all your bugs, but even getting 20% of bugs identified at the earlier stage is a huge boon to development speed.
Is it too late now to start adding unit tests? Kinda YES and NO at the same time. Unit testing works best if it covers the majority of project's code. On the other side, a journey of a thousand miles begins with a single step. If you decide to start refactoring your code, writing a unit test before refactoring will help you to prove to yourself that you have not broken anything without the need of running the game at all.
  1. Static code analysis
This is basically pretty self-explanatory. You set this thing once, you forget about it. Static code analyzer is another «free estate» to speed up the development process by finding tiny little errors, mostly silly typos (do you think that you are good enough in finding them? Well, good luck catching x << 4; in place of x <<= 4; buried deep in C code by eye!). Again, this is not a silver bullet, it is another tool which will help you out with debugging a little bit along with the debugger, unit tests and other things. You need every little bit of help here.
Is it too late now to hook up static code analyzer? Obviously NO.
  1. Code architecture
Say, you want to build Osana, but then you decided to implement some feature, e.g. Snap Mode. By doing this you have maybe made your game a little bit better, but what you have just essentially done is complicated your life, because now you should also write Osana code for Snap Mode. The way game architecture is done right now, easter eggs code is deeply interleaved with game logic, which leads to code «spaghettifying», which in turn slows down the addition of new features, because one has to consider how this feature would work alongside each and every old feature and easter egg. Even if it is just gazing over one line per easter egg, it adds up to the mess, slowly but surely.
A lot of people mention that developer should have been doing it in object-oritented way. However, there is no silver bullet in programming. It does not matter that much if you are doing it object-oriented way or usual procedural way; you can theoretically write, say, AI routines on functional (e.g. LISP)) or even logical language if you are brave enough (e.g. Prolog). You can even invent your own tiny programming language! The only thing that matters is code quality and avoiding the so-called shotgun surgery situation, which plagues Yandere Simulator from top to bottom right now. Is there a way of adding a new feature without interfering with your older code (e.g. by creating a child class which will encapsulate all the things you need, for example)? Go for it, this feature is basically «free» for you. Otherwise you'd better think twice before doing this, because you are going into the «technical debt» territory, borrowing your time from the future by saying «I'll maybe optimize it later» and «a thousand more lines probably won't slow me down in the future that much, right?». Technical debt will incur interest on its own that you'll have to pay. Basically, the entire situation around Osana right now is just a huge tale about how just «interest» incurred by technical debt can control the entire project, like the tail wiggling the dog.
I won't elaborate here further, since it'll take me an even larger post to fully describe what's wrong about Yandere Simulator's code architecture.
Is it too late to rebuild code architecture? Sadly, YES, although it should be possible to split Student class into descendants by using hooks for individual students. However, code architecture can be improved by a vast margin if you start removing easter eggs and features like Snap Mode that currently bloat Yandere Simulator. I know it is going to be painful, but it is the only way to improve code quality here and now. This will simplify the code, and this will make it easier for you to add the «real» features, like Osana or whatever you'd like to accomplish. If you'll ever want them back, you can track them down in Git history and re-implement them one by one, hopefully without performing the shotgun surgery this time.
  1. Loading times
Again, I won't be talking about the performance, since you can debug your game on 20 FPS as well as on 60 FPS, but this is a very different story. Yandere Simulator is huge. Once you fixed a bug, you want to test it, right? And your workflow right now probably looks like this:
  1. Fix the code (unavoidable time loss)
  2. Rebuild the project (can take a loooong time)
  3. Load your game (can take a loooong time)
  4. Test it (unavoidable time loss, unless another bug has popped up via unit testing, code analyzer etc.)
And you can fix it. For instance, I know that Yandere Simulator makes all the students' photos during loading. Why should that be done there? Why not either move it to project building stage by adding build hook so Unity does that for you during full project rebuild, or, even better, why not disable it completely or replace with «PLACEHOLDER» text for debug builds? Each second spent watching the loading screen will be rightfully interpreted as «son is not coding» by the community.
Is it too late to reduce loading times? Hell NO.
  1. Jenkins
Or any other continuous integration tool. «Rebuild a project» can take a long time too, and what can we do about that? Let me give you an idea. Buy a new PC. Get a 32-core Threadripper, 32 GB of fastest RAM you can afford and a cool motherboard which would support all of that (of course, Ryzen/i5/Celeron/i386/Raspberry Pi is fine too, but the faster, the better). The rest is not necessary, e.g. a barely functional second hand video card burned out by bitcoin mining is fine. You set up another PC in your room. You connect it to your network. You set up ramdisk to speed things up even more. You properly set up Jenkins) on this PC. From now on, Jenkins cares about the rest: tracking your Git repository, (re)building process, large and time-consuming unit tests, invoking static code analyzer, profiling, generating reports and whatever else you can and want to hook up. More importantly, you can fix another bug while Jenkins is rebuilding the project for the previous one et cetera.
In general, continuous integration is a great technology to quickly track down errors that were introduced in previous versions, attempting to avoid those kinds of bug hunting sessions. I am highly unsure if continuous integration is needed for 10000-20000 source lines long projects, but things can be different as soon as we step into the 100k+ territory, and Yandere Simulator by now has approximately 150k+ source lines of code. I think that probably continuous integration might be well worth it for Yandere Simulator.
Is it too late to add continuous integration? NO, albeit it is going to take some time and skills to set up.
  1. Stop caring about the criticism
Stop comparing Alex to Scott Cawton. IMO Alex is very similar to the person known as SgtMarkIV, the developer of Brutal Doom, who is also a notorious edgelord who, for example, also once told somebody to kill himself, just like… However, being a horrible person, SgtMarkIV does his job. He simply does not care much about public opinion. That's the difference.
  1. Go outside
Enough said. Your brain works slower if you only think about games and if you can't provide it with enough oxygen supply. I know that this one is probably the hardest to implement, but…
That's all, folks.
Bonus: Do you think how short this list would have been if someone just simply listened to Mike Zaimont instead of breaking down in tears?

A detailed summary of every reason why I am bullish on ETH.

The following will be a list of the many reasons why I hold and am extremely bullish on ETH.

This is an extremely long post. If you just want the hopium without the detail, read the TL;DR at the bottom.

ETH 2.0

As we all know, ETH 2.0 phase 0 is right around the corner. This will lock up ETH and stakers will earn interest on their ETH in return for securing the network. Next comes phase 1 where the ETH 2 shards are introduced, shards are essentially parallel blockchains which are each responsible for a different part of Ethereum’s workload, think of it like a multi-core processor vs a single core processor. During phase 1, these shards will only act as data availability layers and won’t actually process transactions yet. However, their data can be utilised by the L2 scaling solution, rollups, increasing Ethereum’s throughput in transactions per second up to 100,000 TPS.
After phase 1 comes phase 1.5 which will move the ETH 1.0 chain into an ETH 2 shard and Ethereum will be fully secured by proof of stake. This means that ETH issuance will drop from around 5% per year to less than 1% and with EIP-1559, ETH might become a deflationary asset, but more on that later.
Finally, with ETH 2.0 phase two, each shard will be fully functional chains. With 64 of them, we can expect the base layer of Ethereum to scale around 64x, not including the massive scaling which comes from layer 2 scaling solutions like rollups as previously mentioned.
While the scaling benefits and ETH issuance reduction which comes with ETH 2.0 will be massive, they aren’t the only benefits. We also get benefits such as increased security from PoS compared to PoW, a huge energy efficiency improvement due to the removal of PoW and also the addition of eWASM which will allow contracts to be programmed in a wide range of programming languages, opening the floodgates for millions of web devs who want to be involved in Ethereum but don’t know Ethereum’s programming language, Solidity.

EIP-1559 and ETH scarcity

As I covered in a previous post of mine, ETH doesn’t have a supply cap like Bitcoin. Instead, it has a monetary policy of “minimum viable issuance”, not only is this is a good thing for network security, but with the addition of EIP-1559, it leaves the door open to the possibility of ETH issuance going negative. In short, EIP-1559 changes the fee market to make transaction prices more efficient (helping to alleviate high gas fees!) by burning a variable base fee which changes based on network usage demand rather than using a highest bidder market where miners simply include who pays them the most. This will result in most of the ETH being paid in transaction fees being burned. As of late, the amount which would be burned if EIP-1559 was in Ethereum right now would make ETH a deflationary asset!

Layer 2 Scaling

In the mean time while we are waiting for ETH 2.0, layer 2 scaling is here. Right now, projects such as Deversifi or Loopring utilise rollups to scale to thousands of tx/s on their decentralised exchange platforms or HoneySwap which uses xDai to offer a more scalable alternative to UniSwap. Speaking of which, big DeFi players like UniSwap and Synthetix are actively looking into using optimistic rollups to scale while maintaining composability between DeFi platforms. The most bullish thing about L2 scaling is all of the variety of options. Here’s a non exhaustive list of Ethereum L2 scaling solutions: - Aztec protocol (L2 scaling + privacy!) - ZKSync - Loopring - Raiden - Arbitrum Rollups - xDai - OMGNetwork - Matic - FuelLabs - Starkware - Optimism - Celer Network - + Many more

DeFi and Composability

If you’re reading this, I am sure you are aware of the phenomena which is Decentralised Finance (DeFi or more accurately, open finance). Ethereum is the first platform to offer permissionless and immutable financial services which when interacting with each other, lead to unprecedented composability and innovation in financial applications. A whole new world of possibilities are opening up thanks to this composability as it allows anyone to take existing pieces of open source code from other DeFi projects, put them together like lego pieces (hence the term money legos) and create something the world has never seen before. None of this was possible before Ethereum because typically financial services are heavily regulated and FinTech is usually proprietary software, so you don’t have any open source lego bricks to build off and you have to build everything you need from scratch. That is if what you want to do is even legal for a centralised institution!
Oh, and if you think that DeFi was just a fad and the bubble has popped, guess again! Total value locked in DeFi is currently at an all time high. Don’t believe me? Find out for yourself at: https://defipulse.com

NFTs and tokeniation

NFTs or “Non-Fungible Tokens” - despite the name which may confuse a layman - are a basic concept. They are unique tokens with their own unique attributes. This allows you to create digital art, human readable names for your ETH address (see ENS names and unstoppable domains), breedable virtual collectible creatures like crypto kitties, ownable in game assets like Gods Unchained cards or best of all in my opinion, tokenised ownership of real world assets which can even be split into pieces (this doesn’t necessarily require an NFT. Fungible tokens can be/are used for some of the following use cases). This could be tokenised ownership of real estate (see RealT), tokenised ownership of stocks, bonds and other financial assets (which by the way makes them tradable 24/7 and divisible unlike through the traditional system) or even tokenised ownership of the future income of a celebrity or athlete (see when NBA Star Spencer Dinwiddie Tokenized His Own NBA Contract.

Institutional Adoption

Ethereum is by far the most widely adopted blockchain by enterprises. Ethereum’s Enterprise Ethereum Alliance (EEA) is the largest blockchain-enterprise partnership program and Ethereum is by far the most frequently leveraged blockchain for proof of concepts and innovation in the blockchain space by enterprises. Meanwhile, there are protocols like the Baseline protocol which is a shared framework which allows enterprises to use Ethereum as a common frame of reference and a base settlement layer without having to give up privacy when settling on the public Ethereum mainnet. This framework makes adopting Ethereum much easier for other enterprises.

Institutional Investment

One of Bitcoin’s biggest things it has going for it right now is the growing institutional investment. In case you were wondering, Ethereum has this too! Grayscale offers investment in the cryptocurrency space for financial institutions and their Ethereum fund has already locked up more than 2% of the total supply of ETH. Not only this, but as businesses transact on Ethereum and better understand it, not only will they buy up ETH to pay for their transactions, but they will also realise that much like Bitcoin, Ethereum is a scarce asset. Better yet, a scarce asset which offers yield. As a result, I expect to see companies having ETH holdings become the norm just like how Bitcoin is becoming more widespread on companies’ balance sheets.

The state of global markets

With asset prices in almost every asset class at or near all-time highs and interest rates lower than ever and even negative in some cases, there really aren’t many good opportunities in the traditional financial system right now. Enter crypto - clearly the next evolution of financial services (as I explained in the section on DeFi earlier in this post), with scarce assets built in at the protocol layer, buying BTC or ETH is a lot like buying shares in TCP/IP in 1990 (that is if the underlying protocols of the internet could be invested in which they couldn’t). Best of all, major cryptos are down from their all-time highs anywhere between 35% for BTC or 70% for ETH and much more for many altcoins. This means that they can significantly appreciate in value before entering uncharted, speculative bubble territory.
While of course we could fall dramatically at any moment in the current macro financial conditions, as a longer term play, crypto is very alluring. The existing financial system has shown that it is in dire need of replacing and the potential replacement has started rearing its head in the form of crypto and DeFi.

Improvements in user onboarding and abstracting away complexity

Ethereum has started making huge leaps forward in terms of usability for the end user. We now have ENS names and unstoppable domains which allow you to send ETH to yournamehere.ETH or TrickyTroll.crypto (I don’t actually have that domain, that’s just an example). No longer do you have to check every character of your ugly hexadecimal 0x43AB96D… ETH address to ensure you’re sending your ETH to the right person. We also have smart contract wallets like Argent wallet or the Gnosis safe. These allow for users to access their wallets and interact with DeFi self-custodially from an app on their phone without having to record a private key or recovery phrase. Instead, they offer social recovery and their UI is straight forward enough for anyone who uses a smart phone to understand. Finally, for the more experienced users, DApps like Uniswap have pretty, super easy to use graphical user interfaces and can be used by anyone who knows how to run and use a browser extension like Metamask.

The lack of an obvious #1 ETH killer

One of Ethereum’s biggest threats is for it to be overthrown by a so-called “Ethereum killer” blockchain which claims to do everything Ethereum can do and sometimes more. While there are competitors which are each formidable to a certain extent such as Polkadot, Cardano and EOS, each have their own weaknesses. For example, Polkadot and Cardano are not fully operational yet and EOS is much more centralised than Ethereum. As a result, none of these competitors have any significant network effects just yet relative to the behemoth which is Ethereum. This doesn’t mean that these projects aren’t a threat. In fact, I am sure that projects like Polkadot (which is more focused on complimenting Ethereum than killing it) will take a slice out of Ethereum’s pie. However, I am still very confident that Ethereum will remain on top due to the lack of a clear number 2 smart contract platform. Since none of these ETH killers stands out as the second place smart contract platform, it makes it much harder for one project to create a network effect which even begins to threaten Ethereum’s dominance. This leads me onto my next reason - network effects.

Network effects

This is another topic which I made a previous post on. The network effect is why Bitcoin is still the number one cryptocurrency and by such a long way. Bitcoin is not the most technologically advanced cryptocurrency. However, it has the most widespread name recognition and the most adoption in most metrics (ETH beats in in some metrics these days). The network effect is also why most people use Zoom and Facebook messengeWhatsApp despite the existence of free, private, end to end encrypted alternatives which have all the same features (https://meet.jit.si/ for zoom alternative and Signal for the private messenger app. I highly recommend both. Let’s get their network effects going!). It is the same for Bitcoin. People don’t want to have to learn about or set up a wallet for alternative options. People like what is familiar and what other people use. Nobody wants to be “that guy” who makes you download yet another app and account you have to remember the password/private key for. In the same way, Enterprises don’t want to have to create a bridge between their existing systems and a dozen different blockchains. Developers don’t want to have to create DeFi money legos from scratch on a new chain if they can just plug in to existing services like Uniswap. Likewise, users don’t want to have to download another browser extension to use DApps on another chain if they already use Ethereum. I know personally I have refrained from investing in altcoins because I would have to install another app on my hardware wallet or remember another recovery phrase.
Overthrowing Ethereum’s network effect is one hell of a big task these days. Time is running out for the ETH killers.

Ethereum is the most decentralised and provably neutral smart contract platform

Ethereum is also arguably the most decentralised and provably neutral smart contract platform (except for maybe Ethereum Classic on the neutrality part). Unlike some smart contract platforms, you can’t round up everyone at the Ethereum Foundation or any select group of people and expect to be able to stop the network. Not only this, but the Ethereum foundation doesn’t have the ability to print more ETH or push through changes as they wish like some people would lead you on to believe. The community would reject detrimental EIPs and hard fork. Ever since the DAO hack, the Ethereum community has made it clear that it will not accept EIPs which attempt to roll back the chain even to recover hacked funds (see EIP-999).
Even if governments around the world wanted to censor the Ethereum blockchain, under ETH 2.0’s proof of stake, it would be incredibly costly and would require a double digit percentage of the total ETH supply, much of which would be slashed (meaning they would lose it) as punishment for running dishonest validator nodes. This means that unlike with proof of work where a 51% attacker can keep attacking the network, under proof of stake, an attacker can only perform the attack a couple of times before they lose all of their ETH. This makes attacks much less financially viable than it is on proof of work chains. Network security is much more than what I laid out above and I am far from an expert but the improved resistance to 51% attacks which PoS provides is significant.
Finally, with the US dollar looking like it will lose its reserve currency status and the existing wire transfer system being outdated, superpowers like China won’t want to use US systems and the US won’t want to use a Chinese system. Enter Ethereum, the provably neutral settlement layer where the USA and China don’t have to trust each other or each other’s banks because they can trust Ethereum. While it may sound like a long shot, it does make sense if Ethereum hits a multi-trillion dollar market cap that it is the most secure and neutral way to transfer value between these adversaries. Not to mention if much of the world’s commerce were to be settled in the same place - on Ethereum - then it would make sense for governments to settle on the same platform.

ETH distribution is decentralised

Thanks to over 5 years of proof of work - a system where miners have to sell newly minted ETH to pay for electricity costs - newly mined ETH has found its way into the hands of everyday people who buy ETH off miners selling on exchnages. As pointed out by u/AdamSC1 in his analysis of the top 10K ETH addresses (I highly recommend reading this if you haven’t already), the distribution of ETH is actually slightly more decentralised than Bitcoin with the top 10,000 ETH wallets holding 56.70% of ETH supply compared to the top 10,000 Bitcoin wallets which hold 57.44% of the Bitcoin supply. This decentralised distribution means that the introduction of staking won’t centralise ETH in the hands of a few wallets who could then control the network. This is an advantage for ETH which many proof of stake ETH killers will never have as they never used PoW to distribute funds widely throughout the community and these ETH killers often did funding rounds giving large numbers of tokens to VC investors.

The community

Finally, while I may be biased, I think that Ethereum has the friendliest community. Anecdotally, I find that the Ethereum developer community is full of forward thinking people who want to make the world a better place and build a better future, many of whom are altruistic and don’t always act in their best interests. Compare this to the much more conservative, “at least we’re safe while the world burns” attitude which many Bitcoiners have. I don’t want to generalise too much here as the Bitcoin community is great too and there are some wonderful people there. But the difference is clear if you compare the daily discussion of Bitcoin to the incredibly helpful and welcoming daily discussion of EthFinance who will happily answer your noob questions without calling you an idiot and telling you to do you own research (there are plenty more examples in any of the daily threads). Or the very helpful folks over at EthStaker who will go out of their way to help you set up an ETH 2.0 staking node on the testnets (Shoutout to u/superphiz who does a lot of work over in that sub!). Don’t believe me? Head over to those subs and see for yourself.
Please don’t hate on me if you disagree about which project has the best community, it is just my very biased personal opinion and I respect your opinion if you disagree! :)

"Is there going to be a split?"

This question is (understandably) asked all the time by people coming to the BCHN telegram for clarity on what has become a pretty unclear situation. It's not an easy question to answer, though, so I wanted to make this post that people could refer to. Here's my take on answering that question:
It's impossible to know 100% for sure if there will be a split, because it's impossible to know for sure how all the relevant parties will behave. For there to be a split, two node implementations need to irreconcilably disagree on a consensus-related issue, both need to release code with those conflicting consensus rules, and then miners need to also be split enough on the issue for both chains to have enough hashpower to be viable.
The narrative that there is ALMOST DEFINITELY going to be a split seems to have been dumped on us out of nowhere a month or so ago, along with what I consider to be increasingly unreasonable behavior from Bitcoin ABC. The tin foil hat in my heart finds that suspicious. (And between the IFP and recent Grasberg proposal, it almost seems like ABC is doing it's best to propose things that make a split as likely as possible.) This political baggage doesn't really matter though, in the grand scheme of things.
What matters is that BCHN is, as far as I can tell, just trying to be a reasonable and professional node implementation for Bitcoin Cash. If sticking to those principals leads to a divergence from ABC on a consensus related issue, whatever issue that actually would end up being, then that's how it will be. And it wouldn't be the case that "BCHN split the chain", nor would it be the case that "ABC split the chain". It would just be the case that two groups released node implementations with different consensus rules from each other. (And then, if a non-negligible amount of hashpower mines using both clients, then there would indeed be a chain split caused by that situation.)
Keeping BCH unified is obviously a HUGE priority for BCHN. Their initial release of what was effectively a non-IFP version of Bitcoin ABC was even designed so that, if the IFP activated with a majority of the hashpower, miners mining with BCHN would follow that longer chain, instead of rejecting IFP blocks as "invalid" or anything like that. This is in stark contrast to the narrative I've seen flooding this sub recently with claims that BCHN tried to split the chain this past upgrade, and are trying to split the chain again this November. So please take the time to consider which sides of these inevitable disagreements are being reasonable, and which are not, make sure to fact check and ask for sources for any claims you see being made that you can't verify or debunk on your own, and remember that, while chain splits are messy unfortunate things (at least in the short term), if there's an irreconcilable disagreement, it's definitely better for those parties to go their separate ways. I hope that that doesn't have to happen anytime soon for BCH.

Small reviews of (I think) all incremental games I've ever played on Android

I don't know if this will be useful to anyone. So I write a line or two about every game I play, and decided to find all the incremental in my game journal and post them here. It starts with the latest games I've played and I think goes back to several years back. One thing I've realized is I have such a love-hate-hate relationship with this genre since I think I've hated 90% of the games and 100% of myself after each incremental phase. I usually angrily stop playing them for a while and restart them again, so this is more or less a journal of addiction, I suppose.
THE BEST GAMES I'VE PLAYED ARE THESE (no order):
  1. Kittens Game
  2. Antimatter Dimensions
  3. Oil Tycoon
Honorable Mention: Eggs, Inc
The rest: more or less hated it
Additional comment if you decide to scan through it, I complain a lot, so it is perfectly reasonable and normal to think, "why the fuck are you even playing these games, idiot??".

------
Time Idle RPG
This game was confusing. It tells me the game's resources is time, where you get 1 of it every second, but that's not really something as unique as I assumed. It would have been cool if time as resources meant you used it to deal with something related to time. Maybe time travel? Maybe slowing and speeding time?
Instead time as resource buys you stuff like a library. And then you buy a camp or something. Honestly, I wasn't really feeling it.
2
Path of Idling
The biggest cardinal sin for me when it comes to incremental is when a game has a lot of features and it just completely throws them all at you instantly. The joy of a great incremental is how things slowly open up and each new achievement feels progress.
The game is a RPG game and these are the things that opened up for me in the first few hours.
Combat which includes normal fighting, dungeon, raid, boss, PVP (locked, but it just needs an ascend, which I haven't done)
Skills
Hero upgrades which include Passive (strength, defence, stamina, intelligence), Train, and a huge Tree
Town which you can buy workers who get you various things like gold, orbs, knowledge, etc. You can upgrade stuff here.
Quest that also includes Perks and Skill quests.
Gear which 5 equipment slots, plus craft plus trade plus smelt
Also gear for your Pet, which is also another tab!
Now, here is the thing. Because I have all of this pretty much instantly, I don't really know which ones are helping me go past a well. How is adding 10 points in strength helping me? Should I have added five in strength instead and five in defence? I have already bought 20 or so upgrades in the Tree, but I have no idea if I am made the optimal choice. There is no real excitement with getting new gear. And so on.
The dev has added a lot of features, now it's time to rework the game, and have the features take their time.

Idle Slayer
The game is like a super simple platformer. Your character is running and any enemy it hits, it automatically slays it. There is no HP, and all enemies die in one shot. Your only active play is jumping occasionally to grab coins or hit the flying enemies. Also, you have a run skill that has a cool down.
With the coins, we get new weapons that give us more coins. Enemies give us souls which is used for the prestige system that provides us with an interesting skill tree which provides a lot of choices on the path you want to do in terms of upgrades.
So far excellent, however, the game has an extremely serious issue of pacing. The game initially progresses so fast that in the first hour or so, you get almost all the weapons aside from the last two, which then grinds down to a snail pace. You can upgrade your past weapons, but they never really get into play again. Reaching high levels of past weapons sometimes gave me upgrades of that weapon of 10,000% but they still did nothing to my overall coin per second. I think the pacing needs to be fully reworked. It would have been nice to get new weapons after certain prestige cycles, so that every new weapon feels like we have passed a significant wall. The best part of an incremental game for me is to face a wall, and when I finally break it, I feel powerful again for a while. This game feels like this though, powerful powerful powerful powerful WALL........break it....WALL. And so on. I'm still playing it as I want to get some of the skills, but I feel like it could have been so much better.

Exponential Idle
A very back to the foundation kind of incremental. The premise is that you are a student and working on a formula. There is a neat story where as you progress in the game, your character progresses through university. Each upgrade gives you more and more automation until I reached a stage where I would check back once every 2 or 3 days, click a 2nd layer prestige reset, and close it. Meaning the game was something like 5 seconds of game player every 2 days. I just opened it for this review and realized I had reached the end game. The story wraps up and it tells me "You can take a rest. Travel a bit. Go outside!" NO, DON'T TELL ME WHAT TO DO GAME.
3
Factoid
Factoid & Spark should have the same review as they are almost the same game with only small differences. The games are the most basic kind of incremental, where you buy something with resources, until you get the next thing which gives you more of the resources. Both give you upgrades to speed things up, and finally prestige and it's own prestige upgrades. That's it. It's nice little change of pace from all the recent incremental that sometimes do too much, but obviously due to the very simple nature of it, it does eventually feel pointless, specially after you more or less open up everything and the prestige upgrades just keep repeating.

Antimatter Dimensions
Easily top 5 incremental on mobile. Does everything perfectly. You progress nicely, and when new features open it, not only is it rewarding but more importantly, it keeps adding new dimensions (lol) to the game. I'd at the end game as I write this, and I realize that there was no point in the game where it felt stale. Each new prestige layer made the game feel fresh and almost like a new incremental game.
5
Melvor Idle
It seems this game was mainly aimed at Runescape players, which is probably why it didn't click for me. It also run extremely slow on my phone which also played a part in me not really getting into.
2
A Girl Adrift
The animation is really pretty and is a nice change of pace for incrementals, but I didn't really like the too much active play. Really had to keep going back and forth to different areas to do the fishing which got too repetitive for me.
You travel to different areas of the map to catch fish, which you get points and then you upgrade stuff, but I didn't really find any real excitement about the upgrades because I kept having to go back to previous areas to fish similar creatures.
3
Archer: Danger Phone
I'm really annoyed how terrible of a game this was. Two things I like, the TV show "Archer" and incremental games, and it's done in the most lazy manner. The game is the worst aspect of idle games where it's just a straight path of clicking the next upgrade with absolutely zero decision making. Every once in a while there is a mini game where Archer gets to shoot others but it's done in the most basic form of early 2000s flash games, where the animation budget is probably 3 dollars. Same static background and both enemies and Archer have just two animation frames. The absolute laziness of it is almost insulting to the player, because it feels like we aren't even worth the effort.
There is an Archer story in the game which develops really fast, which is the only positive part, but no voice acting is again another evidence that the creators of the game weren't given any budget for this.
1
Home Quest
This game is way too slow. You have to collect materials to build your settlement but everything takes time, so you click for a few seconds, and then you have to leave the game. Which I'm fine with, but the problem isn't the idle part of it, it's how the idle part of it combines with constant checking of the game which annoys me. I like an idle game where you forget to start the game for a day, you come up to a lot of resources, but this is a game which needs you to check back in every 30 minutes or an hour to really get anywhere. I felt that the micromanagement was getting worse as I progressed (without any actual thing to do when I am active in the game) that made me give up.
2
Idle Industry
This is probably an interesting game, but I gave up because the one thing I really disliked was the amount of resources and manufacturing that very quickly opens to you. You can buy raw materials, and you can either sell these raw materials or turn them into finished goods and sell them either. And each of these has several upgrade options (increase selling price, increase production, etc). Without even really getting too deep into the game, I have around 20 raw materials and around 30 finished products. A satisfying part of this genre is to have things slow open up for you, which gives me a decent feeling of satisfaction. But the money I got would quickly open up new products, so I would just jump ahead and purchase more expensive ones, and after a while I had a lot of materials and products at zero, and was instead focusing on latter ones.
2
Masters of Madness
Somewhat neat atmosphere and visuals, but too much active clicking. Click, upgrade to get more per clicks, get minions to get you some points without clicking, typical clicker, but with the added benefit of almost no idling. I like idling incrementals but clickers is a hard no from me.
1
Soda Dungeon 2
Basically similar to the first one, as far as I could tell. I did "finish" it but maybe I shouldn't have, since it really is the same thing from early on, specially once you get all the heroes and you kind of sort out which characters work best, then it's just the same. But because it was somewhat short and no real wall, it was at least easy to stick to it to the end.
2
Bacterial Takeover
Played for a decent amount and was actually more interesting that I thought, given the buttload of ad incentives. You create and upgrade bacteria, attack planets, and eventually go into a blackhole to prestige. Most of the game was good, but the part that killed it for me was the prestige system. Once you prestige, planets get super easy to attack, which becomes a lot of active play. I realized that each prestige was taking me at least 30 minutes to get to where I was, and it was just meaningless clicking. It got to a point where I was putting off prestige because it seemed like it would be a hassle so I stopped.
2
LogRogue
Cute graphics. The hero sort of hopping to hit the tiny monsters is cute to look at, but how long can you look at it and do nothing before you realize that it's boring? I suppose this is a game where it's just not for me. I don't like to have my phone open on a game and just watch it like a crazy person and do nothing. My rule is simple for incrementals. While the app is open, be active, if there isn't any choices to make, close the app while resources build up or whatever. I don't like it being open while I do nothing.
3
A Kittens Game
Incremental games are so strange. I get in and out of the phases. I loved this for so long and so obsessively that I wanted to only play incremental games. And then, just like that, I was wondering why the fuck I was wasting my time with this. Has happened countless times before.
But still probably the best incremental ever.
5
A Dark Room
An incremental cult classic of sorts but I don't find it really matches the genre. There is a bit of incremental at the beginning with people huts and stuff but then its just a ascii exploring game, which wasn't interesting to me.
2
Little Healer
Saw it mentioned in the Reddit incremental forum in one of the posts and thought it was a healer themed incremental which sounded neat. But it's like being a healer in a raid in World of Warcraft without any if the extras. Just a couple of bars representing your team mates and you healing them while they fight the boss. I didn't even like playing the healer in WoW so no way would I play this game.
1
Clickie Zoo
Started playing for a few days until I realized there a beta released with the dev reworking the game completely from scratch and releasing it as "Idle Zoo Tycoon". So, played that instead but this seemed like a game I would enjoy anyway.
4
Idling to Rule the Gods
The UI and one drawing if your character is really ugly enough to be distracting to me. The game, seemed interesting and I eventually was into it, but seems like a game that has been constantly being updated, which is not always a good thing, because features are obviously updated regularly to it, making the whole thing a bit bloaty.
I guess, this is the problem with this game for me, it's too fat. Also, one main part of the game is that your character creates Shadow Clones up to a maximum limit. Which is fine except the clones can't be made in offline mode. This might not be a big deal in its original web browser game but that doesn't work as well in a mobile format.
2
Realm Grinder
This is one of the really popular incremental and it's fanbase seems to love it for it's depth, but to be honest, I don't play these games for the depth, I play it for the simple dopamine rush of doing the same thing over and over again. It relaxes.
Although, I didn't even get to the depth part because I dislike games where it rushes in the beginning. I constantly bought buildings, got spells, and got upgrades without even looking at the description. Apparently, later on, we can get complicated race upgades, which seems not what I'm looking for in such a genre.
2
Spaceplan
A short (!!) incremental with an actual story (!!!). That's two cool points for it but unfortunately, the game mechanics of increment genre isn't so good. It's a space game with nice visuals and a great ending (cool music set to cool graphics) but the game itself wasn't really that fun. This same exact game would have been better in a different genre (maybe something like "Out There"?)
3
Zombidle
Felt like idle games again and this is the kind of examples that kept me away. Too much clicking and seems like advancement will start to get irritating since it relies on IAPs
2
Eggs, Inc
While I was playing it, Eggs, Inc was probably my favorite Android game I had ever played. But like most incremental games, there comes a moment when I suddenly stop and think, what am I doing?
Because there is something fascinating about Incrementals. Their addictiveness is in a way the whole point. An incremental is less of a game and more an act of electronic addictiveness. What's the point?
Eggs, Inc is a very well made and fun incremental but even the best in its genre is still pointless.
4
Castle Clicker
Supposedly a mix of incremental and city building but didn't really find out since the clickings were way to much. I know this is supposed to be the genre but I like the incremental part more than the tapping part. This seemed to be a good way to hurt your fingers.

Endless Era
This RPG clicker game is like other such games but with horrible GUI and animations. Tap tap tap. It's my fault for downloading such games. Why would I ever think this would be fun???
1
Idle Quote
An incremental game with a unique twist. This time we get to make up quotes! The first negative about the game and this irritates me a lot is most of the quotes are fake. A quick search on Google and this proves it. Quotes are generally attributed to Buddha or Ghandi or shit like that and it's usually fake like most quotes on the internet. This kills the major possible advantage of the game because I thought coming up with arbitrary words would at least give me some quotes to learn. Aside from the this, the game isn't fun either because it slows down very quickly meaning you combine words very slowly at a certain stage of the game and then it becomes a boring grind.
2
Monster Miser
An incremental game with almost no graphics. We just see character portraits of monsters which we buy and then upgrade until we buy the next monster. Eventually we prestige which gives us multipliers. The only game choice is choosing between two monsters with each new monster with unique benefits. Annoyingly there is a max limit which I wish didn't exist because I wanted to prestige so much that I would be over powerful in upgrading like that "Idle Oil Tycoon". Still, pointless but reasonably fun.
3
Pocket Politics
An incremental take on politics sounds fun but it's so generic that it could have been about anything. A Capitalist idle game or a cooking idle game, it wouldn't matter. IAP was also the usual shitty kind.
1
Time Clickers
A shooter incremental sounds like a cool twist but it's not a FPS like I imagined it would be. I'm just stuck in a room and I was shooting blocks. Upgrades didn't give me any enjoyment since I was shooting fucking blocks.
1
Tap Tap Fish - Abyssrium
I thought this was going to be relaxing incremental but the ridiculous and generic IAPs and all the social integeration spoil it. Too much time is spent in them asking you to buy or share or tweet or post or give them a blowjob. And there is nothing relaxing about that.
2
Cartoon 999
Incremental game about comic book writers, but not the marvel DC kind, it seemed to be the webcomic one and I think it's a Korean developer so all the characters and injokes made no sense to me. The whole thing was just targeted to a very specific audience.
2
Dungeon Manager
Incremental games need to be simple but this is beyond simple, it's just upgrade a fighter to level 5, go to next dungeon character, do the same, and just continue without any of the delicious balancing of upgrades like other idle games.
2
Final Fortress
Incremental games are already pointless but when it's super heavy on IAP than its also annoying, but when it always has bugs that doesn't register my offline earnings, then it just needs a uninstall in its face.
The zombie skin was also crappy.
1
Mana Maker
Here is how I know this clicker isn't very good. It doesn't make me hate all clickers and my life and mobile gaming in general for being so addictive and pointless.
So fail, sorry.
2
Infinity Dungeon
The usual incremental RPG that I should probably never play again. Starts simple enough and then gets more or a chore as you play.
1
Another incremental game which I had promised myself not to play anymore because they are so pointless and repetitive and endless. Well, this wasn't infinite and had a goal at 999 level so I thought it was good but while the humor was cute, the game did become very repetitive. Every 10 levels the slimes changed but after every 100 levels the whole thing restarted and while the monsters got stronger, I seemed to get even stronger. So the game became easier as I progressed and there was no more challenge. By level 800, I gave up.
2
Tap Dungeon RPG
Okay, I'm running out of ways to complain about those incremental RPG games that all have similar problems. It starts off reasonably fast and fun but soon it seems like I am in a data entry job. Doing the same thing over and over again with little changes.
1
Dungeon 999 F: Secret of Slime Dungeon
Another incremental game which I had promised myself not to play anymore because they are so pointless and repetitive and endless. Well, this wasn't infinite and had a goal at 999 level so I thought it was good but while the humor was cute, the game did become very repetitive. Every 10 levels the slimes changed but after every 100 levels the whole thing restarted and while the monsters got stronger, I seemed to get even stronger. So the game became easier as I progressed and there was no more challenge. By level 800, I gave up.

Tap Dungeon RPG
Okay, I'm running out of ways to complain about those incremental RPG games that all have similar problems. It starts off reasonably fast and fun but soon it seems like I am in a data entry job. Doing the same thing over and over again with little changes.
1
Tower of Hero
You start on the first floor of the tower and keep fighting your way up by summoning your heroes (by clicking) and recruiting other fighters, get upgrades, level up, and then, ugh, here is the typical incremental RPG part, restart, get items, and do it ALL over again.
There is something fun about restarting and getting slowly stronger each time but it also feels so pointless after a while. Such a pointless genre now that I have played a billion of such titles, heh.
3
Pageboy
Yet another incremental RPG which I have no idea why I downloaded because I'm sick of the genre. I played a pageboy to a knight who does the fighting while I collect the lot. I collect the loot, buy stuff for the knight, and eventually I restart to do the same thing again and get better items but this game I didn't even RESTART! Because fuck it! Fuck it!
2
Idle Warriors
The story is cute. Human population is regressing while monster population is on the rise. So the humans start enslaving monsters to mine for them! The brave warriors beat the crap out of monsters, kidnap the bosses, and enslave them. The animation of monsters slaving away while speech balloons above them talk about their wife and children is funny.
But the game itself is another RPG incremental which I should start staying away from. These games are like a chore for me nowadays because I'm doing the same crap again and again. The blame is probably on me because it seems like a reasonably solid game. But hey, fuck it, I PERSONALLY didn't enjoy it.
2
Tap! Tap! Faraway!
Any game that is remotely like Tap Titan scares me. They are addictive at first and very fast moving but after every restart gets more and more annoying. It soon turns into a time eating activity with the player having to redo the initial levels to get relics to get better items to progress further to restart to get relics to and so on until the player realizes how much time he is putting in the game for a repetitive activity.
2
Auto RPG
Now that is a title the game developers didn't spend too much time on. RPG battles are automatic but I can help out by clicking like a mad man. I started with one hero but would get additional members in my party as the story progressed. Party members receive skills as as they level up and while all the skill usage is automatic, it did give me a sense of progression which is extremely important in a RPG and which I think is usually lacking in incremental games. It usually starts feeling useless but in this game at least there are new maps, new members, and an actual end sight!
There is an infinity stage once the last boss is defeated but I am glad the infinity stage happens AFTER the end and it's not the game itself.
4
Merchant
Hire a hero and send on to battle. The battles is done automatically and takes time, starts with something short like 10 seconds with each battle taking longer. The loot is raw materials which can be used to craft equipment which also takes real life time with better items taking longer. The crafted items can either be sold or equipped to the hero to make him be able to fight stronger monsters.
I was worried I would hate the longer crafting and fighting times because I hate games which I have to watch for a task to finish but even though the durations for longer, I had more to do. However, I don't know what would have happened in the end game because I gave up on it. New maps were exactly like the first map just with different heroes but the progression was similar in each level which felt that I was doing the exact same thing all over again but with longer task times.
2
Idle Oil Tycoon
This is the best idle game I played. It's graphics aren't just minor, they are none existent. It's just numbers, so basic that my sister thought I was on a stock market app.
It's such a simple concept. Invest, get oil, upgrade then like other idlers restart to get a bonus and do the full thing all over again. When I finished the game, I played the unlimited mode which I played until the unlimited mode couldn't handle the numbers anymore.
5
Soda Dungeon
This kind-of Idle Dungeon was great. I started with weak ass fighters who would fight on my behalf while I collected the loot. I then got to use the lot to upgrade the sofa bar to recruit more adventurers. Not sure why it was a sofa bar. Maybe they wanted to make it a family game and not have alcohol? Sounds weird but the sofa element in a RPG game sounds weirder.
The game only hit a brick for me when, like most other incremental games, there is no real closure. Once I thought I bet the big bad guy, it just goes on, harder but similar enough with no end in sight. Eventually, we have to stop playing right, but it always feels a bit like a let down when I don't feel like I have finished the game.
4
10 Billion Wives Kept Man Life
The two games from this company, 10 Billion Wives and Kept Man Life, have similar strengths and weaknesses.
I liked the silly premises from both. In 10BM, I had to get married as much as I could, using the loves I collect to marry more expensive wives! In KML, I'm a boyfriend who doesn't work and I have to please my career gf so she would take care of me.
Both start reasonably fast and I was willing to grind through difficult parts but the end game is like a brick wall. Passing through it to get all the achievements is pretty much impossible unless one puts in way too many hours. And it's a shame because I really wanted to get all the achievements to see all the tiny little extra stuff.
3
Adventure Capitalist
One of the better incremental games, but now that I am out of the short lived incremental fan phase, I realized how dumb the genre is. Tap, tap, tap, upgrade, do this a million times, reset, and do it all over again like a moron. The game does deserve credits for me acting like a moron and playing it for so long but I also cheated and got free cash and then if occupying became even more pointless.
3
The Monolith
A combination of an incremental and a civilization building game seemed like an excellent idea and in some ways, it was, specially how we get to upgrade through the ages from cavemen to futuristic. But no offline feature means that the resets aren't enticing.
2
USSR Simulator
An incremental game that has a great theme (USSR!) but absolutely horrible to enjoy, even though I did stick to it. After a certain upgrades, the game just turned into me popping in the game, clicking an upgrade and then forgetting about the game for a few days.
2
RPG Clicker
They should call these games tappers not clickers. We are not clicking anything on a touchscreen device. Anyway, tap tap tap level up buy weapons tap tap and uninstall.
1
Logging Quest Logging Quest 2
[Review is for the original and its sequel]
There is not much of a difference between the game. I actually played them both at the same time because the actual game is offline. You choose your hero, send them to a dungeon, and then come back to the game after a while to see how well they did. I thought an offline RPG like this might be interesting but then, if you don't really play a game, how much fun can it be?
1
Another pointless incremental. I was in an incremental phase and got so many incremental games that I know realize were absolutely pointless.
Hit a tree, buy upgrades, get a new hero, and continue hitting a tree. Not much offline it seems which is what I like about incrementals.
1
Galaxy Clicker
A space incremental that should have been a lot of fun. You get to upgrade your spaceship and buy new ones and explorer new planets. But first of all, the interface is so ugly that it makes playing the game less enjoyable. And a lot of things I didn't really get no matter how much I would play like the full exploring planets. The spaceships were nice, so it could have been fun.
2
Megatramp
A pretty pointless incremental kind of game. You are a tramp and then you can collect money to buy upgrades to make more money, with no strategy needed, nor any effort needs to be made to hurt your brain cells.
1
Inflation RPG
It supposed to be some kind of incremental RPG, I think, which has you resetting and getting more powerful and then fighting monsters to get insane levels. It is very unique but I couldn't get into it.
2
Widget RPG
Are you fucking with me? This is button bashing rpg in the most extreme manner. You get a widget, so you don't even have to open the game and distract yourself from the button bushing. Just click the button and the game plays behind the scenes and gets you experience, loot, and kills.
It's a ridiculous idea that is fun for a few minutes to see what they come up with but there is only so much button bashing you can do.
2
Capitalist Tycoon
I downloaded this game because I was in an incremental/idle game phase and really enjoyed AdVenture Capitalist. But this game is nothing like that. On the surface, it seems similar, buy small investments, make money, buy bigger investments, and so on.
But with this game, there is no offline mode, and you keep having to wake up managers, AND the goal is to see how much you make in one year. Bah. I prefer the incremental approach which makes you build and build and build, not try to rush it in just a year.
2
Clicking Bad
An incremental clicking game that is themed after Breaking Bad. It is a fun idea it's a very simple game with little to do aside from the obvious of upgrading and upgrading. The only twist might be to balance out making lots of money selling drugs and not attracting the law but even that is only a small challenge at the start. Eventually, you will get enough upgrades to bring the law risk so down that it makes no impact on the game play.
2
Zombie Tapper
A super basic incremental clicker game with a zombie team. Click click click to eat brains, use brains (?) to buy zombies to do the brain eating for you and then buy upgrades for your zombies, and buy new zombies and it all feels very pointless.
1
Bitcoin Billionaire
I started to enjoy incremental games, but it needs to have a good offline mode, because I don’t want to just play a game where I keep tapping. But that doesn’t mean I didn’t play. I played it, and I played a lot of it, because I could reset the game (like most incremental games) and it gives you a small benefit where you could finish the full game a bit faster (it gives you bonus income). So, I kept finishing and resetting, and each time the start to finish would shorten, so I thought I would reach a stage where I could finish each start-to-finish in an instant! It didn’t happen. I got bored first.
3
Tap Titan
An addictive tapping game. Just tap on the creatures, level up, get new skills, hire heroes, and then reset and to it all over again to progress further. It’s an incremental game where it depends on resets to progress, but no real offline bonus, so you have to be playing online. Which got boring, so I installed an app that does the tapping for me, which is actually a stupid way to play the game, but this isn’t an attempt to prove to anyone my intelligence. Anyway, thankfully something went wrong and my progress got deleted, WHICH WAS A GOOD THING, because the game was extremely addictive.
4
God Squad
I’ve realized most incremental games are stupid. Tap on monsters to kill, collect gold, buy Roman Gods, level them up, fight other monsters, and then get bored.

Technical: Taproot: Why Activate?

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

Summary

I Wanna Be The Taprooter!

So, do you want to help activate Taproot? Here's what you, mister sovereign Bitcoin HODLer, can do!

But I Hate Taproot!!

That's fine!
