Groestlcoin 6th Anniversary Release
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
Dave Bitcoin of walletrecoveryservices.com just cracked a wallet for me (whose passphrase I lost in May).
Background: In May I got the "brilliant" idea of beefing up the security of my BitcoinQT wallet by replacing its password with a longer passphrase. Somehow I managed to mistype the passphase twice. I tried every thing I could think of (adding spaces, inverting capitalization, etc. etc.) but without success, even automating the guesses with a simple script from someone on bitcointalk. Eventually I wrote the coins off and my next wallet passphrase was typed with extreme caution. (Plus I switched to using Armory where the paper backup feature is a nice safety valve.) I gave the wallet.dat file to a few people who contacted me via the bitcointalk forums, and thought that was the end of it. So last night, I'm obsessively watching the BTC-CNY exchange rate like everyone else, when I get an email from one "Dave Bitcoin" who announced that he had cracked the passphrase (after more than 5 months!). In short order he sent me 2.0 of the original 2.5 BTC in the wallet (keeping a finder's fee we had agreed to when I originally sent him the wallet file, not that I was in a particularly good bargaining position). It was a very pleasant surprise that he (a) was able to crack the wallet, and (b) was honest enough to return the coins. He mentioned in the email that part of his motivation for (b) is that he has started a business doing wallet recovery. I figure the least I can do is vouch for his competence and integrity. So all you morons out there who lost a wallet like me, consider using Dave's services at http://walletrecoveryservices.com/.
01-13 07:43 - 'Lost Bitcoin passphrase: Does anyone have any experience with the new recovery tool Passware Forensic Kit?' (self.Bitcoin) by /u/NitrousNed removed from /r/Bitcoin within 5-15min
''' Here's my situation..... I know this is an all too common problem (and you've probably heard a lot of similar stories) but I'd appreciate any advice I can get. I purchased some bitcoins back in 2013. They were in a Bitcoin-QT wallet on my now very old and slow Macbook (which I still have). However, I wrote my passphrase on a piece of paper that is long gone now! I'm well aware that without the passphrase or seed phrase I'm unable to recover the coins. HOWEVER, I might know part of the passphrase - but not too sure. I've now created a new BitcoinCore wallet and have imported the located the wallet.aes.json or wallet.dat file from the old mac (just waiting for the initial synchronization which should be finished in a couple of days. I know it is difficult (if not impossible) to crack the passphrase via brute-force but I just heard about new Forensic software called Passphrase ([[link]2 ) that apparently has the ability to recover lost bitcoin passwords from Bitcoin.info and Bitcoin Core wallet services. It is very expensive (USD$1,095/year) but just wondering if anyone has used it before or knows how effective it will be in my situation. Hoping someone can help!!!!! Thanks ''' Lost Bitcoin passphrase: Does anyone have any experience with the new recovery tool Passware Forensic Kit?

Hi guys. I realize this is pretty dumb, but I've lost the passphrase to my old Bitcoin Core wallet. I've tried quite a few bruteforcing apps with no luck (duh), old backups(no use), wallet recovery services(not interested) et cetera. Thanks for staying this long with me. Almost there. So, why I'm here is - I'm going to share my old wallet.dat's and ask y'all to crack them. As a reward you can keep 50% of money in the wallet, which is 5$ and not a cent more. That should make around 70$. Now, I perfectly understand that if you do manage to get the money, nothing would be stopping you from taking all of them. Well, on the other side I believe that it still would be better than the money laying w/o use. Besides, Redditors are awesome. The passphrase is about 13 digits long, with no repeating symbols. The minus is that it can contain any keyboard symbols (Uppercase, lowercase letters, numbers, and [email protected]#...) The files (wallet.dat backups) are up on google drive - https://drive.google.com/drive/folders/0B3eCKZXI79O8aklyUUk5WXBtWGc?usp=sharing I wish you good luck. P.S: Sorry for the, uhm, title. P.P.S: English isn't my native language, so have some mercy. P.P.P.S: I can provide any ownership proofs. Say, dance around my PC with transaction history onscreen? P.P.P.PS: Yes, I'm fully aware of the fact that I'm not very smart.
So i bought some coins thru coinpal in 2011. I have the email which contains the bitcoin address that the coins were sent to, at some point in 2012 or something, i lost interest in bitcoin. reformatted and repurposed the drives, etc. but i did backup my wallet files, and after searching i found a wallet.dat file that is compatible with the old bitcoin qt client under the recieve tab, it shows 3 addresses, one of which has no label, The second has the address contained in the email from coinbase, and the third has another address that i believe i had sent coins to at some point. The two "labels" i can search on blockchain.info and they both have a balance. HOWEVER.. when you right click copy address, it copes an entirely different address. this address has a zero balance. in all 3 spots. So ive tried importing the wallet into bitcoin core, it does not show anything, so i know this is an older file created by the older bitcoin qt client. ive run several commands in the debug console, trying to dump the private keys, but for some reason the wallet file i have does not contain the private keys for the two addresses that have coins. I had someone trying to help me but he says the wallet is encrypted. so i opened the debug console and tried to unlock the wallet using the passphrase i think i would have used, and it tells me that the wallet is not encrypted which makes sense because i remember specifically not encrypting the wallet because i always forget passwords. Whats weird is, how did these addresses get put into the label section of the recieveing tab? i know for a fact that one of them which contains 2btc i could have manually entered myself, because i do have a record of the address on my email from coinpal. the second one tho, i have no idea where i would have found the address. They both have one transaction right around the same time, and they both have a balance. one of 2btc, one of .4 btc. the transaction dates line up to when i bought the coins. im having data recovery done on my hard drives at this point to look for more bitcoin wallets, because im pretty sure i had more bitcoins in there as well. at least 6 or 8 more that i can remember. So is it possible that the wallet file is corrupt? if so is it repairable? or is it more liekely that ADDRESSES listed in the recieve tab are the actual addresses contained in the wallet file, and the labels are something else? im ripping my hair out trying to figure this out.. I have a wallet file. it has 2 addresses listed which i can verify both have a balance, but i cannot gain access. i remember in 2011 buying some coins, and like the next day my computer crashed and got stuck in a boot loop so i had to reformat. and i remember backing up my wallet on a flash drive, and trying to restore it and the coins not showing up even after the blockchain loaded. i have not yet finished loading the blockchain on my bitcoin qt app, so maybe that has somethign to do with it, but i find it odd that these addresses do not have the correct private keys. any ideas?
Hey everyone, Let me start with some background info. After sending my bitcoin originally to my bitcoin core address, my unknowing self decided it might be a good idea to delete everything including the wallet.dat (had no idea what I was doing). I used recovery software to retrieve the wallet.dat but there was some overwriting done. Enough that when I open core, A message appears that reads, "error reading wallet.dat! All keys read correctly but transaction data or address book entries might be missing or incorrect." Also, when I go to the console command line and try to enter my walletpassphrase to unlock my wallet so I can dump the private keys, it says that walletpassphrase is incorrect. I am almost positive that what I wrote down is exactly what I entered when setting up the wallet. Along with trying what I wrote down, I also tried unlocking the wallet with hundreds of slight variations to no avail. So what my question is, did deleting the wallet or the overwriting of parts of the wallet make the encryption passphrase no longer valid or different? Also thoughts on whether the partial overwriting of the file will prevent me from obtaining the private keys or not are appreciated. Lastly, if anyone has any alternative methods to brute force the wallet pass phrase they would be greatly appreciated. I heard about [email protected] and if anyone could share their experiences with them if they used them.
I have several wallet.dat with bitcoins,one of them 30.28 btc,second 1 btc,third some btc.In all I forgot my passphrases to my wallets.I ask wallet recovery services no success.I use pywallet with web version,after I click change passphrase,bitcoin core was closed,nothing worked,and my passphrases dont changing.What I do wrong?What alternative methods for change passphrase?or send btc directly with bitcoin core on my coinbase account?
I have a very old wallet, which I am unable to open. It is password protected, but I know what the password is. Bitcoin Core says Salvage failed. Booted LiveUSB Ubuntu and installed pywallet. [email protected]:~/Desktop/pywallet$ sudo ./pywallet.py --recover --recov_device /dev/sdc1 --recov_size 1Gio --recov_outputdir /home/ubuntu/Desktop/recove Enter the passphrase for the wallet that will contain all the recovered keys: 123456 Enter the possible passphrases used in your deleted wallets. Don't forget that more passphrases = more time to test the possibilities. Write one passphrase per line and end with an empty line.

Do you want to test them? (y/n): y Private keys not decrypted: 221 Try another password, check the size of your partition or seek help The wallet is encrypted and the passphrase is correct Importing: The new wallet /home/ubuntu/Desktop/recove/recovered_wallet_1513352751.dat contains the 0 recovered key [email protected]:~/Desktop/pywallet$ So it recognizes the password as correct, but it doesn't decrypt the keys. Please help.
If you missed the previous parts: Part 1Part 2 Let us continue. Fear not those who have kept up so far - we are almost there... When you’re playing your favourite game you’re always moving forward. Anything you do is a step in the right direction. If you fail you get to start back at checkpoint somewhere – this is true for most games, Day Z probably being one of the exceptions. The point is, you get a sense of that progression – it’s a nice feeling and it keeps you going. What happens when you don’t get that sense of progression?... Friday 28th March – still here. It’s now the afternoon and I’m staring at my monitor. The progress bar moving along at a snail’s pace with a message telling me ‘weeks to go’. Agonising. Some of you probably think it’s over, move on, you only invest money that you can afford to lose, etc. Your right, couldn’t agree more. The problem is hope. I mentioned in Part 1 that I class myself as an IT savvy person and in Part 2 that I like a good challenge. Well this was it – I wanted to see if I could make use of that knowledge and find a break through. Earlier that day, after my wife woke up, I told her what had happened, she listened intently. Her response? ‘You’re a clever IT guy, I’m sure you will find a way.’ I chuckled a little. So what else can I do? Dave Bitcoin hasn’t got back to me yet. Is there anything else out there? Turns out there is: Enter TheGrideon. They have developed a Bitcoin Wallet Password Recovery application. Windows installer? Check, CPU & GPU utilisation? Check, Brute Force / Mask Based / Dictionary attacks? Check, check and check. Price? FREE FOR PERSONAL USE. Now were talking. Installation was as easy as 1-2-3. As soon as the application ran it detected my two AMD cards and the CPU I was using. All that was required was to point it to the wallet.dat and supply it with some information. Magic. I played with it for a bit, testing its capabilities by attempting a simple brute force and supplying characters I thought made up my password. It started ticking away; 10 passwords a second, 100 passwords a second, 30 seconds later 2500 passwords a second (!) before finally settling on 4500 passwords a second (!!!). This was it, if I was ever going to crack this passphrase, this would be the tool that would be the tool to do it. Friday the 28th March had come and gone. Seemed like a bit a blur now that I think about it. There was so much going on in my head that time seemed to fly by. I got stuck into the application, made sure I knew exactly how it worked and therefore how best to utilise it. As I was progressing I got an E-mail response from Dave Bitcoin! (Hurray). He’d got my messages and the information I supplied was fine however he asked a couple more specific questions; How sure was I about the characters I sent, what attempts have I made, etc. Ultimately he brought me back down to reality: a 12 + character password will be an impossible task if I can’t be more specific than I was. I guess hope is one of those things you cling on to until there’s no hope left. I didn’t want to give up. I supplied Dave with the additional details, gave him a general confidence rating. It was enough to get him started. In the back of my mind I was already thinking I shouldn’t be relying on Dave alone and so I continuing doing my own thing. Saturday rolled around and I was still at it – I’d realised there was a little problem with the application; it didn't have a permutations option. This was a pretty big deal. As I mentioned in Part 2, permutations is the one thing I was 100% certain about… so I e-mailed their support team. Fantastic is the word that comes to mind when I refer to their support team. They were not only on the ball, they were bloody quick about it. I received a response within the hour. Their software was unable to handle permutations however they directed me to the dictionary functionality and mentioned that there are some online permutation generators that I could use to build a dictionary. It was the saving grace for the application. I immediately jumped online and searched for permutation generators. I found this little gem. It was perfect for what I needed. It accepted prefixes, suffixes and allowed for 10 characters to be entered. Since I had a good idea of what my prefix and suffix were there was a lot of potential for this to work. I began using it straight away. 8pm Saturday. Where the hell has the day gone? I had literally been working through the entire day doing nothing but creating dictionaries, supplying the application with those dictionaries and sitting there staring at my screen. Nothing. Not a single dictionary I had created / used returned my passphrase. I was beginning to hit the wall. In answer to my question at the beginning of this post; sense of progression is everything. It’s pointless to continue. You give up. You stop playing. I removed myself from Reddit, from Dogecoin and from my laptop for a while. I stopped thinking wallets and passphrases altogether. You know what they say though….. It’s not over until the fat lady sings [Part 4] tl;dr
Google F****** Keep (didn’t think I was gonna forget you!)
Response from Dave Bitcoin, he offered his assistance!
Found another tool to help password recovery
Full CPU+GPU support – 4600 passwords a second!
Found a permutations generator for dictionary creation
Attempted millions and millions of permutations
Nothing, not a single dictionary contained the passphrase
Frustrated, angry and ultimately feeling defeated - I give in.
If you missed Part 1 – check here! The story continues! (tl;dr at the bottom) Where were we… ah, my alarm. No sooner did I jump into bed than the alarm went off! Buzzing away under my pillow… the day was fast turning into one of the worst days of recent memory. I grabbed my phone, switched the alarm off and just lay there mumbling. ‘A1 something something something £9 something something’ ‘No, that’s not right’ ‘A1 #?’ ‘What was it – I know this, come on … visualise!’ I’ve never done that before… I was speaking to myself out loud, that was the gravity of the situation and my feelings at the time. I hate you Google Keep!!... My wife on the other hand had already dozed off (btw, I got plenty of confused.com looks during the panic station ‘moment’, she was half asleep though so it didn’t really faze her). Eventually I began to calm down. I started thinking sensibly about the situation. The first thing I was doing wrong was not writing down any of my guesses. I probably recited well over 30 phrases as I was lying there. I got up, opened my laptop and started writing them down. At the same time I noticed my mining rig was still running... RDP -> Hit Q on CGMiner – why the hell was I mining coins to address that I no longer had access to!!!! Once the fans slowed I opened the QT client and went to the send tab. Bear in mind that from the moment I lost my password to this moment I hadn’t even attempted a single passphrase even though it would have been a little fresher in my mind! Send tab -> check the addresses I have saved -> ah DogeTipBot -> that will do. 100 coins, hit send… ‘Please Enter Passphrase’. Ok here goes: First attempt ‘That’s the one for sure...’ Nope -Tries again- No -and again- Error -A further 15 times- Access Denied. Sigh F*** you Google Keep. (Yeah your gonna see a lot of this – I despise that app now). I must have tried and failed countless times before I decided to investigate other options. What do you do when you’re stuck? Google It. And that’s what I did. There were a fair few posts regarding lost pastphrases, none of them really helpful. Most replies were along the lines of ‘sorry for you loss’, ‘how much did you lose?’ and ‘nothing you can do…’. Well, screw that, I wasn’t giving up – I like a good challenge! Enter Recoinvery.com. A nice little tool albeit very slow. I came across it whilst searching for passphrase recovery options available to me specifically for coin wallets. You basically point the tool to your wallet.dat file, set a bunch of options and hit the ok button. It runs a few instances in the background attempting to recover your lost passphrase. Let me stop there for a sec and explain something quickly about passwords and recovery of one (feel free to correct me if wrong!):
If you’re trying to recover a password less than 10 characters that you can’t remember at all then there’s a decent chance for you to recover it – it may take a while though, could be months.
If you know bits and pieces of it then you can drastically reduce the time it takes for recovery using things like dictionaries or masks
If your password is 10 characters or over and you don’t know parts of it then you’re pretty much screwed
There’s more to it than just that but those are some of the key points most recovery websites will throw at you. Another vital point I learned was the difference between combinations and permutations – it goes a little like this: If I have a password ‘Abcd123’ then there’s no reason for me to check combinations – I.e. aaaaaaa, aaaaaab, aaaaaac, etc. We’re not interested in combinations here, were interested in permutations. With permutations you would provide a character set and a length you are after – this would then output unique permutations of the character set vs. the length – using the password example above, if I provided Aabcde12345 as the set and 7 as the length I would see things like Aabcde1, Aabcde2, Aabcde3, etc. (Remember ‘A’ and ‘a’ are not the same) Why is this key for me? I was 100% sure that I hadn’t used the same character twice in my passphrase. So, back to Recoinvery. As I said, great little tool but I quickly realised it was far too slow for what I was trying to achieve. There had to be other services out there. There were tools like Hashcat and John The Ripper, both great for expert hackers / crackers but for me, a novice when it comes to this type of activity, I found those tools a little out of my league. At this point I came across www.walletrecoveryservices.com – a service provided by a guy called Dave Bitcoin. You’re thinking what I’m thinking right? Scam Scam Scam. Best course of action? Google It. Dave was apparently the real deal. His method was a custom made bit of code + access to numerous workstations / servers and the use of only a small section of your encrypted wallet. This is key – the portion he was asking for was essentially useless, he wouldn’t have been able to steal my coins had he recovered it. I read up on it and him – everything seemed above board. I proceeded to contact him. In the background, I had Recoinvery chugging away at measly 100 passwords a second – it had been running for hours I think (btw this is still Friday the 28th March) and nothing. My guess would be somewhere in the region of 500,000 combinations had been checked of a 12 character password (+ it seemed a little … buggy). Wait you say? I’ve not said a word about what parameters I’ve used or what the hell it was that I was trying to look for! Fear not, details below:
I was fairly sure my password was not less than 11 characters and certainly no more than 13
I knew it had unique characters, symbols and numbers
I knew the start and the end of the password – 99% confidence
I was about 60% sure about the characters contained within the password
It was the bit in the middle that had be stumped. The good news was I was able to provide Recoinvery with a mask – set a prefix, suffix and let it chug away at the middle. The bad news, as highlighted earlier, I was struggling with permutations and speed. It was frustrating to say the least. Approaching the half day mark with nothing to report I decided to check back on Reddit to see if any more comments had been made that may guide me (I made the most in the morning before 9). A couple of useful comments however nothing to go off. I guess it was time for a little patience… woosaaaa. I should probably get some breakfast… (12.00pm) Am I doomed? It's looking increasingly likely I know .... Hitting the Wall [Part 3] tl;dr F****** Google Keep Calm down – think sensibly Research password recovery, find Recoinvery Give Recoinvery some character sets to work with Sit and wait.
(On 23rd March 2015) Wallet Recovery Services is AWESOME!
Hi everyone. i would like to take a moment to share my personal experience for having mistype my passphrase/password for my Digibyte Desktop Wallet. It all began when i changed my old passphrase to a new one. How i would normally do it was to first type out a random password in notepad that has upper and lower cases, numbers and special characters. Once done, i would copy and paste it into the passphrase box. Lastly, i would refer to the notepad and write down the password onto a piece of paper. 3 months later and after several deposits, i wanted to withdraw some Digibytes. When i referred to the piece of paper and typed the passphrase, it didn't worked!!! I tried again thinking that i might have mistype. And then i tried every other password that i thought i might have mis-copied and paste. Everything failed. It was difficult for me to recall exactly what happened since it was 3 months ago. I tried Recoinvery. But it didn't worked out so well for me. I did thought of trying the Ruby Method but it was much too complicated. I was about to give up and thought that i should just keep the wallet.dat and hopefully somewhere in the nearby future, some service would appear. But Lo and Behold!!! it has already appeared ever since 2011: WALLET RECOVERY SERVICES. I was skeptical at first, not knowing much about it. But as i researched more and read the reviews, comments and testimonials that others had given about it, and saw that it has been kept well up-to-date by being able to offer their services for not just Bitcoin but for altcoins as well...i thought i should give it a go. Furthermore, it mentioned that Blockchain.info redirects their clients with forgotten passwords to this service. About 5 hours later after sending an email to Wallet Recovery Service, i received an email...with good news - my passphrase had been successfully decrypted!! THAT WAS FAST! And it was all because of a mistype - a "$" was included into the password somewhere in between, an additional character. Either i mistype the passphrase twice (really? twice? facepalm) when i change it OR i have no idea how i could have missed that when i copied it down onto a piece of paper. And guess what? among the 25 passwords that i had created, the one i mistyped had to be the shortest one (14 characters long). The ironies... I will be leaving a link to this GREAT Service: http://www.walletrecoveryservices.com/ I know i'm not an old timer here on Reddit. But i don't exactly have any other way to prove that this is a true story. I guess i could at least share my activities on the Digibyte Forum. That should helped a bit i hoped. Here is my profile: https://bitcointalk.org/index.php?action=profile;u=224866 If you are still not convinced, then one way is to do your own research about it, read through all the testimonials and the information provided on the website about how to get it done. Thanks for reading everyone. This service will be MUCH SOUGHT for in the future when we have more people coming into the Bitcoin and Altcoin Scene. Let's help to keep it alive and spread the word! Once again, THANK YOU Wallet Recovery Services!!! ()/
