This torrent's purpose is to make bringing new clients that store the blockchain locally online faster. Instead of downloading from the network, you can download from the bittorrent network, which in some cases is faster, an then import the raw block data into your bitcoin client.
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.

Unpack the file (large file, takes around 15 minutes to unpack): sudo xz -d bootstrap.dat.xz ↳ Screenshot
After a successful unpack, your will find the file bootstrap.dat in your USB root folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
The welcome screen will appear and ask you about the data directory. I suggest a new folder on your USB drive, I picked blockchain. The directory will be created with all the necessary files. ↳ Screenshot
Click on the three dots (...) on the right. ↳ Screenshot
Click on Create Folder at the upper right corner. Type and enter in the folder name. (In my case: blockchain.) Click on Open. ↳ Screenshot ↳ Screenshot ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Move the bootstrap.dat file to your data directory you selected in the previous step. By doing this, Reddcoin Core will use the bootstrap.dat file to import the blockchain, which speeds up syncing. sudo mv bootstrap.dat /media/rpi3b/usb/blockchain/ (Assuming blockchain as data directory.) ↳ Screenshot
The Reddcoin Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Keep the client running until it's fully synchronized. It will use the bootstrap file first, and download the rest of the blockchain to complete the sync. This can take some time (it took 2 days for me). Syncing the blockchain uses a lot of resources, so the software may react slow.
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen! ↳ Screenshot
When synchronization is complete, you can start staking your Reddcoins.
You can write down your private key or copy and save it in a document. Make sure you save it somewhere only you can access it.
To import later: Debug window -> Console -> importprivkey [label] [label] is optional. ↳ Screenshot (without a label) ↳ Screenshot (with a label)
Boot with only 1 USB drive plugged in: Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly. If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
Start Reddcoin Core easier Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
Right Click on your Desktop and select Create New -> Empty File. ↳ Screenshot
Enter a file name, make sure it ends with .sh, and click on OK. I've chosen for Reddcoin.sh. ↳ Screenshot The file will be created on your Desktop. ↳ Screenshot
Add the command to start Reddcoin to the file.
Right click on the file, select Leafpad (to open the file in a text editor). ↳ Screenshot
Add the following to the file and save the file: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
To be able to execute the shell script (.sh), it has to have 'execute permissions'.
Right click on the file, and select Properties. ↳ Screenshot
Click on the Permissions tab.
For Execute, select Anyone, and click on OK. ↳ Screenshot
To start Reddcoin Core, double click on the file. A new window will pop-up, asking you what you want. Execute in Terminal is what we want, so you can click on enter. ↳ Screenshot Reddcoin Core will now start. Do not close the Terminal window, you can minimize it if needed.
Minimization options Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
Activate 'Minimize on close'. Settings -> Options... -> Window (tab) -> Minimize on close. ↳ Screenshot Reddcoin will still run when you click on the X button. To close/exit Reddcoin, right click on the Reddcoin icon in the system tray (bottom right corner). ↳ Screenshot
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
After your download is finished, open the file and click Install Package. ↳ Screenshot
To run the VNC Connect once:
Open [Menu] > Run, and enter: vncserver-x11 ↳ Screenshot
To auto run on startup:
Open Default applications for LXSession ([Menu] > Preferences > Default applications for LXSession). ↳ Screenshot
In LXSessions configuration, select Autostart in the menu left.
Under Manual autostarted applications, enter vncserver-x11 and click on + Add. ↳ Screenshot ↳ Screenshot
Reboot your Raspberry Pi and check if VNC Connect is started automatically after the reboot.
When VNC Connect is running, you'll see a VNC icon on the right bottom corner. Double click the icon to open VNC Connect and to see the IP address you need to enter to connect to your Raspberry Pi. ↳ Screenshot
There is a discussion about nodes that came up today, where it seems I'm discouraging people from running the full QT/Core client. Yes and No. What I'm trying to make sure people understand is how things work, and that it is NOT mandatory to run a client in order to use Dogecoins (and yes, I realise that browser-based tools like coinb.in and wallet sweepers are 'clients' by strict definition). That said, more nodes is absolutely a good thing for the network. Preferrably full nodes. How do you run a full node? Just run Core/QT and open up Port 22556 on your router so it can connect to more than 8 peers. What will it cost you? You need your machine to be on 24/7/365, you need enough storage for the full blockchain (currently about 20Gb. Bitcoin is over 120Gb) and enough bandwidth to keep it in sync and share blocks with peers. A couple of Gb a month, most likely. This is best done with a desktop on a wired broadband link. Or maybe a hosted VM in the cloud. :)
EDIT 2017-01-09: Wallets WITHOUT Clients
Since I started helping people on /BitcoinBeginners, I'm getting a lot of questions about how to use wallets without running clients or trusting third parties. So here are a couple of resources that will make that possible, and not just for Dogecoin: Multi-Coin Wallet GeneratorNow supporting 129 currencies!Coinb.in Start by setting the currency, found in the gear wheel in the Broadcast tab. Dogecoin Wallet Sweeper Redeem 'paper' wallets containing up to about 100 UTXOs. Bitinfo Charts My favourite block explorer, handles a bunch of cryptos. Using these resources, it is possible to hold, receive and spend coins in various currencies, without having to run QT or a 'lite' client. You can also download and run the pages on your own device.
EDIT 2016-11-23: SEMANTICS about MINING! :P
Even though there is already a section on mining below, it has been suggested given the huge number of posts on the subject that this needs to be made clearer. Since people get their panties in a twist over the word 'dead', lets change that...
MINING IS DEAD!
MINING DOGECOIN IS UNPROFITABLE!
Put simply, there is no way to mine Dogecoin and make a profit because of the massive hashpower provided by industrial-scale Litecoin miners. Mining Doge directly stopped being viable when our hashrate exploded with the introduction of AuxPoW. Mining with CPU's and GPU's died when ASICs were introduced. And mining with a laptop WILL kill your laptop and cost you a fortune to repair or replace. Mining Litecoin with an exchange that also mines Doge and others will earn less than the electricity consumed, and you won't recover your costs. Probably ever, but certainly not in any reasonable time. Mining other currencies may be a thing, but that's beyond our scope here. This is /Dogecoin, not /GetRichMiningCryptos after all. If you want to mine the newest scamcoin for fun and profit, look elsewhere for advice. :/ Oh, and most important:
READ BEFORE YOU POST!
At any given time, there are half a dozen posts on the frontpage just like the one you're about to write, where the answers have already been given. Read them. Don't make people waste their time repeating themselves because you were too lazy to bother reading stuff. :P So there I was, having a quiet Sundy arvo bludge, as you do, when 42points turned up on Facebook and asked me to write a new sticky post for /dogecoin. Why would he do this, when he should be having a bludge himself, I hear you ask? Well, seems he was doing exactly that, and wanted to fob off the work he’s too slack to do himself. ;) Ah well, being a sucker for punishment, I’ll grudgingly oblige I guess. OK, first things first.
A client is a piece of software you keep on your computer which holds one or more wallets. Here are the current client versions. If you're using an older client please upgrade to the newest version prior to sending/receiving coins. Backup! Backup! Backup your wallet.dat file or private key so you can import them into the latest version of the client.
Be warned that unless you’re running Core (aka QT), you could have issues with wallets containing lots of UTXOs (Unspent Transaction Outputs - Where your coins REALLY live). Go read the ELI5 below, and keep a close eye on your transaction counts. If you DO run Core, realise that all full clients, regardless of the coin, require a copy of the blockchain and must keep it up to date. This will cost you time, storage space and bandwidth. You can save a little by downloading the bootstrap file though. I haven’t checked how recent this one is, so let me know if you find a more current version.
OK, so next, grab this wallet generator. Even if you plan on running a client(s). Because a) it does many, many cryptocurrencies, and b) you WILL need wallets at some stage over and above what you keep in your clients. Just be sure to run it locally (and offline if you’re truly paranoid).
Oh, and here’s a simple way to keep track of all your wallets using HTML. You can grab the source and modify it, then upload it wherever you need to suit your needs. You will also want a separate file with your private keys, but don’t upload that one anywhere, because if you lose your keys or someone else gets access to them, you will lose your coins.
Next, be aware that there are online wallets available. While any wallet you don’t own the keys to isn’t actually yours, and therefore isn’t safe, the following are safer than most. Dogetipbot of course is used daily by shibes on Reddit. Block.io uses multisig and gives you Doge, BTC and LTC wallets as well as testnets, and Dogechain gives you your private keys (and also offers a wallet sweeping service).
Exchanges also offer wallets, of course. Not that you should use them to store your hard-earned coins, because they can and do get hacked with monotonous regularity. But at some stage you’re going to want to trade, or hold a few uncommon coins. You could do worse than these three:
And then there’s the obligatory question of mining. Put simply, mining is for all intents and purposes dead, and has been for a long time now. The costs are greater than any possible returns. But, if you insist on doing it anyway, maybe because you inherited a miner, you can earn about 0.01 LTC/day per MH/s merge-mining at Litecoinpool. That’s about 4 cents. :(
Shibes sometimes complain that the devs are not as active in /dogecoin as they used to be. You can find them on IRC, slack or their very own sub if you need them though. Or poke sporklin, who can often help.
You can of course ask any questions here, or post them in the sub. However, do try searching first, because I guarantee every possible question has been asked many times before. And you should also subscribe and hang out in /dogeducation occasionally. There’s much awesomeness there.
From peoplma I was wondering if you could add just a couple things. A link to the coinomi android wallet, it's probably the best one out there. And a sentence somewhere along the lines of "if you need help with any dogecoin software you are welcome to make a post, but PLEASE include your OS, version number of the client, and any relevant transaction IDs that you are willing to share" if you can fit that in somewhere. Also, if you want to link to Prohashing, I'm pretty sure it's the only Scrypt mining pool that will actually pay out in doge. The others I know of pay out in litecoin or bitcoin. And it's a profit switching multipool, so gives a better return than just mining ltc/doge. And there's these two wiki articles I thought would be helpful to link /dogecoin/wiki/technical for those technically minded newbies or intermediate users who want to dig a little deeper. And maybe a link to /dogecoin/wiki/dogecoincoreguide next to the link for dogecoin core. From pts2002 Finally a proper sticky post! Here's some other stuff you could add: zpool.ca mining pool - You can get paid in pretty much any coin, and you can mine in multiple algos (currently mining lyra2v2 with my GPU). Doing about 500Ð/day shapeshift.io exchange - My favourite exchange, quick and easy. No registration required! Also, you should add some blockchain explorers! chain.so - Support for bitcoin, litecoin and doge. dogechain.info - Official blockchain explorer. Includes a wallet (already mentioned). Live update currently not working (?) EDIT: Here's another thing I found! preev.com currency value calculator - Easy way to check the value of your dogecoins (or bitcoins, or litecoins, or peercoins)!
I want to stake Reddcoins on my Raspberry Pi, but there is no easy to install package for the Reddcoin Core client. I found some tutorials (mentioned at the bottom, under 'credits'), but I still struggled to get the result I wanted. It took some small adjustments, but I got the GUI Wallet of Reddcoin Core working on my Raspberry Pi Model 3B. See the steps below. :).
If you have any questions or comments, please post a comment in this thread, so others can also benefit from it.
If you would like to tip me: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.
Even though Raspbian is the primary OS for the Raspberry Pi, it seems that it's not possible to build and compile the Reddcoin wallet software for Raspbian Stretch. However, I got the wallet compiled using Ubuntu MATE.
RPi: Raspberry Pi 3 Model B
OS: Ubuntu MATE 16.04.2 (Xenial)
Space needed: I would recommend at least 32 GB. I am using an 8 GB SD card for the OS, and a 128 GB USB drive for data.
The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 1 GB of 'virtual' memory by creating a swap file. After your Raspberry Pi has rebooted, open MATE Terminal again and enter the following commands:
sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
To make sure the swap file persistent (so it survives a reboot), you have to add a line to the /etc/fstab file.
In MATE Terminal, enter the following command to open the file in Pluma (text editor): sudo pluma /etc/fstab
In Pluma, create a new line, add this text: /swapfile none swap sw 0 0 ↳ Screenshot (You should add spaces to vertically align the lines.)
Save and close the file.
Back to MATE Terminal; reboot your Pi: sudo reboot
To see if the swap file is used after a reboot, run: sudo cat /proc/swaps ↳ Screenshot
After the reboot, open MATE Terminal again. Download, unpack, configure, build and install Berkeley DB:
Add this line in Pluma: /uslocal/BerkeleyDB.4.8/lib/ ↳ Screenshot
Save and close the file.
Back in MATE Terminal: sudo ldconfig
Download the source of the Reddcoin wallet and build it:
git clone https://github.com/joroob/reddcoin
sudo ./configure --disable-tests
sudo make ↳ Screenshot (this will take some time; with me it took just over 1 hour)
sudo make install
Speed up synchronizing with the Reddcoin blockchain by bootstrapping.
cd (to make sure your working directory is your home directory)
Download the bootstrap file (1.45 GB): sudo wget https://github.com/reddcoin-project/reddcoin/releases/download/v22.214.171.124/bootstrap.dat.xz
Unpack the file: xz -d bootstrap.dat.xz
After a successful unpack, your will find the file ''bootstrap.dat'' in your home folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo $HOME/reddcoin/src/qt/reddcoin-qt
The welcome screen will appear and ask you about the data directory. I suggest a new directory in your home directory, I picked 'blockchain'. The directory will be created with all the necessary files. ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Use the file manager (Caja) to browse to your home directory and move the ''bootstrap.dat'' file to your data directory you selected in the previous step. Your home directory is the first item in the File Manager in the left menu.
The Reddit Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Launch the Reddcoin Core client again: sudo $HOME/reddcoin/src/qt/reddcoin-qt
Keep the client running until it's fully synchronized. This can take some time (it took 2 days for me).
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen!
Your wallet will be encrypted, and the Reddcoin Core client will be closed. Launch the Reddcore Client again. ↳ Screenshot 4
To stake, you need to unlock your wallet (by entering your password): Settings > Unlock Wallet...
Make sure "For staking only" is checked before clicking OK. ↳ Screenshot
You can only stake with Reddcoins that have matured: coins have to be at least 8 hours in your wallet to mature.
The grey arrow at the bottom should be green when staking. Hover over that icon to see the progress of staking. ↳ Screenshot
Backup your wallet! File > Backup wallet... ↳ Screenshot
Start Reddit on system login. Settings > Options ↳ Screenshot > This works when using only an SD card. > I can't get this to work when using SD card (for OS) and a USB (for data/blockchain).
Adjust minimization options, so you can safely press on the red X (close/exit button). ↳ Screenshot
The default browser, Firefox, stops working and crashes after updating Ubuntu MATE. My solution is installing another browser: Chromium. To install Chromium, enter the following in MATE Terminal: sudo apt-get install chromium-browser ↳ Screenshot You can then access Chromium via [Menu] Applications > Internet. ↳ Screenshot
To remote connect to the Raspberry Pi, I use VNC Connect from RealVNC.
Where do I find the _latest_ bootstrap.dat torrent? I'd like to seed!
I am confused which bootstrap.dat is the latest and what not. No idea if the torrent from bitcoin.org has been updated. Would be nice if anyone could link the latest .torrent so I can jump in and seed it all day long. Thanks!
We have a constant stream of people coming back after abandoning Dogecoin and the sub in 2014 when the price fell. These people all have old versions of QT and are now basically trying to recover their coins, presumably to cash out and abandon us again. This is causing strain for the network, as far more people are trying to leech blocks than seed them. The thing is, none of this is necessary. Especially if you're just going to dump coins. With resources such as https://coinb.in/#settings all you need are your private keys, and you can create, sign and broadcast transactions yourself. No client required, let alone one as resource-hungry as QT.
"So, how do I get my keys?"
First of all, lets talk about data management. The overwhelming majority of coins are not lost through theft, especially direct theft of wallets (as distinct from wholesale thefts/scams/implosions like Moolah, GAW, MtGox, Cryptsy, and even our own beloved Dogetipbot). Most coins are lost because people forget about their wallets and do silly things like reformat hard drives, lose passwords and so on. So, everyone should have a wallet list. Here is a sample bit of HTML that gives you a page with two columns of wallets, one for local wallets you would withdraw coins to, the other the third-party wallets you would deposit coins to third parties through (do note that many services use temporary addresses generated for deposits which expire after 24h or so). A page like this is how I manage my 100+ wallets, and I have copies on my network and hidden online. Such a page makes it easy to at least keep track of all your wallets, for a trivial amount of work to set up.
"OK, great, so now I have a list of my wallets. Now what?"
Now you're going to need the private keys for each of those wallets. Obviously you're not going to store these in a public place though. So you will need a separate file, which can just be plain text. Copy each of those addresses into it. Now go ahead and fire up QT. If you haven't synced it in 3 years, its going to take forever, but that doesn't matter. You don't actually need the blockchain for this, so you don't have to wait for it to catch up. Open up the console which is in the Help menu. Then give the command dumpprivkey with the wallet address you want the key to. Then use the up-arrow key to bring that command back, replace the address with the next one, and keep going until you have them all. It will look something like this:
13:05:18 Welcome to the Dogecoin RPC console. Use up and down arrows to navigate history, and Ctrl-L to clear screen. Type help for an overview of available commands. 13:11:06 dumpprivkey D9xDcRthB6XP4vRGqiyKdDfVJ7CWhYuBBi 13:11:06 6KEcssuq1wWUrFVmMF8yDxHuAdQMiRezz53zDxADLmyoXnix7iM 13:12:00 dumpprivkey DUDARNrGHVTFcCgriwRWgDQJPKDuDQr9jg 13:12:00 6JNk6NNFZcr49fbsD2jcTfTxFLjJKq9DHQ5JU8CYeZ2Cz6JdKMY 13:12:25 dumpprivkey DG6xnwCT6BXePaySqU85XocobZmhbJczQH 13:12:25 6JNXFv95Mp9SzehHw9jojjdxHRNPeh77qCsRbaNwJZMp9MKCAu3
Yes, those are real wallets. But don't bother trying to steal my coins, I just generated them on https://walletgenerator.net/ and they're empty. That's basically it. All you need to do is add some descriptions of what the wallets are, pretty up the format to your liking, and save copies in multiple, secure places, including printed out.
Remember, if you lose your keys, OR someone else sees them, you lose your coins!
If those were my real wallets above, you could use the keys and spend my coins. So obviously, don't let anyone else, especially annoying little brothers, get their grubby hands on them. But also make sure they can be discovered if anything happens to you. That's why the printed copies... nobody is going to go trolling through your porn or warez collection on the offchance there's something valuable in there. But they will look in your safe or wherever you store other important documents. Just be sure to leave a note as to what they are and how to use them. Remember the woman who came here a couple years ago who had found a USB stick with 110 BTC in a locked wallet.dat on it from her dead husband? I sometimes wonder if she ever got the money. Don't be her. Or him.
"OK, great. Now I have my keys. What now?"
Well, you can spend coins using https://coinb.in/#settings from any wallet you have the keys to. First step is to choose the network. Dogecoin (mainnet) obviously. Then go to Transaction in the +New menu. Enter your address and hit the Load button. It will pull in the first 100 transactions. Now enter the address to pay, and the amount. Note the Transaction Fee box! You want this amount to be zero. Depending on whether you're moving coins to another of your wallets to consolidate them (a very good idea.. go read the UTXO ELI5, which you will find a couple pages into https://www.reddit.com/dogecoin/comments/4yts6h/start_here_for_much_wallet_wow/ - Yes, I'm going to make you work for it, cos there's tons of useful stuff there you need to know), or paying someone else, you may want to select which inputs to use. Once you're happy with the transaction, go ahead and submit it. You will now get a block of text, which is the raw, unsigned transaction. Copy this. Go to the Sign tab. Paste it. Add your private key and Submit to sign it. After a little bit, you will get a signed transaction. Copy it. Go to the Broadcast tab, paste it and hit Submit. That's it. It should go into the next block in a minute or two. Yes, even without paying a mining fee. Our network is so lightly loaded that there are no contention issues like the Bitcoin people have to put up with.
"That's it? So why do I need QT?"
You don't. The process above is all that's involved in spending coins. Everything else is window dressing. So there is no need to run QT, or any other client. Oh, and since you can download the site and run it locally (mostly offline), there is no security issue beyond the usual keyloggers/spyware that can compromise anything. And by knowing how to do this, you are much better protected from accidental loss than someone who blindly trusts black boxes they don't understand. Oh, one final thing... if you really want to help the network by seeding rather than leeching, go ahead and run a full node. Instructions are in that link above. AND you may want to help seed the bootstrap file torrent from a couple of days ago. Just because YOU don't need it, doesn't mean others don't, right?

Sorry everyone, this one’s going to be very serious again, and I'm going to start with administrivia. First of all, a few people have mistake me for lead developer recently; I'm not, I'm just the one that’s more vocal and therefore gets attention. langer_hans is lead developer, and has been working on the coin much longer than I have. Quick reminders of a couple of things; for new shibes getting started with the main client, you can download a blockchain bootstrap file which helps you get going faster. So Chain is hosting instructions, and copies of the bootstrap.dat are hosted by themselves and Moolah (see links on that page). We've also seen a few people asking about the 1.7 release; yes it’s out, no you don’t have to upgrade, but it does seem a lot faster to us, so we would encourage upgrading. Also there is a mailing list for announcements of upcoming client releases at https://lists.sourceforge.net/lists/listinfo/dogecoin-releases which I would recommend subscribing to. So, yesterday lleti asked about an idea to see if there was community support for it. A developer asking does not mean something is going to be done. Even if it was done, it does not mean you have to follow (I’ll talk about that in a moment). Feedback to date has been overwhelmingly negative, though, so consider the idea abandoned. A few people asked have why the idea was suggested; the intent would be to remove sharp shocks from the mining schedule, and spread it over a longer period of time in order to give adoption of Dogecoin a chance to catch up. One thing I'm not sure was clear was that there was consideration of changing block time to reduce the resulting inflation. As said, we’re not seeing community support for it. Talking of adoption; /dogecoin has just ticked over 87,000 subscribers. Some Dogecoin users don’t read the subreddit, some subreddit readers don’t use the coin, but lets use that as an estimate for user base. That’s huge for a coin that’s 6 months old, and tiny in terms of an Internet service. And it’s worth remembering Bitcoin is 5 years old, Litecoin 2 years. Peercoin, almost 2 years. That’s the coins we’re in the midst of right now. The developers are cautious of making big technical changes because we want to stabilise the coin so the more cautious companies can know the coin is rock solid, and encourage them to get involved. So, everyone’s been all about the price this week, and while I hate talking price with you guys, I need to as background on a lot of other stuff. So, the DOGE/BTC price is down, yes. DOGE/USD also a bit, but much less. DOGE/DOGE still solid, though. We’re Dogecoin, though, the price shouldn't matter… well, agreed, but it’s worrying people, and in particular there’s a lot of people worrying the price drops will lead to a 51% attack. So lets talk about 51% attacks, and lets also talk forks. A 51% attack is where someone gains control of over 50% of the hashrate of the network, and maliciously uses that hashrate to make their own private blockchain which grows faster than the default blockchain. The malicious part is really important here; it’s an attack, not something that happens accidentally. In doing this, they can spend money on the current blockchain, then release their private blockchain. The network sees the longer blockchain and moves to it as part of the fork handling code (note the fork, it’s important). This effectively reverses the spending of Dogecoin that they’ve done. Note that this is only really an attack on exchanges, as the attacker has to get their Dogecoin into another form (i.e. Bitcoin) before the transaction reverses, or the whole thing has no effect. So far, no exchange has communicated any serious concern about a 51% attack on Dogecoin to myself, and I am unaware of them having done so to any other developer. The concern over price is raised because as Dogecoin rewards per block diminish over time (which they continue to do for the next 6 months or so), the payments to miners become less valuable (in USD/BTC terms) unless the price goes up. Many of our miners are here to support the coin (with thanks to /DogecoinDefenseForce), but some are just here for the money, and people worry that losing them will make it easy to 51% attack the coin. So how does one a get enough mining power to 51% attack a coin? I mean, our hashrate is in the 40-50GH/s range, how do you get 51% of that (or more, if it’s a group not currently mining us)? Well, a hacked mining pool is the main scenario that worries people; it’s considered unlikely any mining pool would decide to attack their own funding source (and the big pools are making big money through entirely legal means). When Bitcoin had the same problem back in January, there was a major push to adopt what is called p2pool, which is a distributed alternative to conventional mining pools. There’s been a few issues with p2pool and Dogecoin which is part of why it’s not more widely used, but I’d really like to see more people looking at it, and talk to the developers about what (if anything) it needs for wider adoption. Ideally I’d like to get all new miners picking up p2pool, so if anyone wants to help with tutorials that would be awesome. A number of other ideas (apart from p2pool adoption) have been proposed; change proof of work, change to proof of stake now, change to proof of stake later, merged mining, multi-protocol mining… all of these have something in common, they require that we fork the coin. Now, a deliberate planned and controlled fork is quite different to a 51% attack fork, but that does not mean that it’s risk free. One scenario would be a disagreement with the developers over path the coin is taking (as we’re seeing with the tapering suggestion), and the community not updating, leaving the developers on their own very small fork. Other scenarios could include significant numbers of exchanges stuck on the wrong “prong” of the fork for an extended period of time. We've had at least one exchange get “stuck” for days or weeks on every fork so far, causing significant confusion and distress to those trying to send coins to or receive coins from the exchange. Same for merchants, who might report not receiving coins if they or the sender are on different forks. Although unlikely, it’s also possible that the fork would introduce a serious bug. There are a number of coins which have been PoW at launch and intended to move to PoS shortly afterwards, and failed to actually switch. Certainly any such change is not without its risks. Lastly, on a personal note, I'm going to be focusing primarily on co-ordination and communication from here on in, rather than working on the code base directly. I’d like to give a shout-out to our many other developers, there are far too many people now involved to name them all, but langer_hans as lead developer, leofidus-ger, patricklodder have all worked extensively on the 1.7 client. Go give them a hug! If any of the community want to get involved with development, please do swing by #dogecoin-dev on IRC Freenode and we can help get you started.
[Quick guide] Run a full node with btcd (an alternative to bitcoin-core) on debian
It's good to run a full node, and even better to run one with an alternative implementation to bitcoin-core. I was surprised how easy it is to install btcd (conformal's alternative implementation of a full node). I was also surprised how little bandwidth a full node uses. This quick guide will get you up and running. To use this method you will need debian testing (Jessie) because the version of golang on debian stable is too old. However, the binary produced will run on debian stable. You will need about 25GB free to store the blockchain, with an extra 20GB or so if you use the bootstrap.dat torrent. Probably the same instructions will work on ubuntu (but using sudo instead of root). INSTRUCTIONS TO RUN A FULL NODE WITH BTCD On debian testing the steps are: 1 - as root, do
2 - pull in and compile btcd and associated utilities as normal user,
$ mkdir btcd; cd btcd; export GOPATH=$(pwd); $ go get github.com/conformal/btcd/...
3 - run your node
$ cd bin $ ./btcd --externalip=YOUREXTERNALIP
(where YOUREXTERNALIP is your external IP address). 4 - on your router, forward port 8333 to the computer your node is running on. Once your node is running, check the port is open with a tool such as canyouseeme.org 5 - enjoy being part of the network! OPTIONAL STEP A (to download the blockchain faster, to be run before step 3): A1 - download Jeff Garzik's torrent to bootstrap the blockchain or the magnet link, magnet:?xt=urn:btih:36719ba2cecf9f3bd7c5abfb7a88e939611b536c&dn=bootstrap.dat&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80&tr=udp%3A%2F%2Ftracker.publicbt.com%3A80&tr=udp%3A%2F%2Fcoppersurfer.tk%3A6969%2Fannounce&tr=udp%3A%2F%2Fopen.demonii.com%3A1337&tr=http%3A%2F%2Fbttracker.crunchbanglinux.org%3A6969%2Fannounce (discussion here) A2 - run as normal user,
Running staking Lore clients paves the way for some of the future use cases of BLK utilising the Bitcoin 0.12 (and newer) core tech, including colored coins. So I'm going to leave this one going indefinitely to kickstart the number of Lore clients staking. It's certainly not mandatory but it will be good in the longer term to have a nice distribution of Lore staking clients.
The cross-compile which lets you create binaries for multiple platforms didn't work for the QT version on the Pi, so there is more to do than just running the binary unfortunately, as below. There are folks working on some much cleaner solutions than this for the Pi, with a custom front end, and where you won't have to do any mucking about. That is coming soon. In the meantime, if you enjoy a fiddle with such things, here's how to get this QT client working on your Pi.
These instructions assume you are starting from scratch with a completely blank OS.
Note they have since (August 2017) released a version called 'Stretch' which does not work with this guide. I'll see if I can come up with something new for that at some point and link to it here when I have. In the meantime the guide should work with the Jessie image above.
Unzip the file and extract the .img file to burn it onto Fresh SD card to boot from (to be safe, use 16GB or larger), using a tool like win32diskimager or Etcher.
Assuming you have keyboard/mouse and monitor plugged into your pi, boot it up and the Jessie Desktop will show.
Before we do anything else, you should increase the default swap size on the pi, as compiling certain libraries can exhaust the RAM and get stuck otherwise. To do this, launch a Terminal window and type:
sudo nano /etc/dphys-swapfile
and Change the CONF_SWAPSIZE from 100 to:
Exit nano with control + x to write out the file.
Then, run the following to restart the swapfile manager:
(If you prefer to compile it yourself instead, it is possible by following the instructions in the original article by Mindphuk just taking into account this is the newer version of the Lore client than when that was written (https://github.com/janko33bd/bitcoin/releases) and the versions of Boost and the Berkeley DB need to be the same as below.)
Double click the zip and extract the Lore binary files. Yes, at the moment they are all called 'bitcoin', not 'blackcoin' or 'Lore' - this is because the code derives from a recent bitcoin core implementation so this has not yet been updated. You can place these wherever you like.
In the Terminal window, change directory to where you put the binaries, e.g.:
cd Downloads/lore-raspberrypi-armv7-jessie-pixel chmod +x *
That marks the binaries as executable.
Now, we need the Boost libraries installed for any of the Lore binaries to work. The project was done with Boost 1.62.0. Unfortunately the Jessie repository only goes up to 1.55, so we need to download and build 1.62 manually on the device.
wget https://sourceforge.net/projects/boost/files/boost/1.62.0/boost_1_62_0.tar.gz/download tar -xvzf download cd boost_1_62_0 sudo ./bootstrap.sh sudo ./b2 install
(This will take almost 2 hours. Have a nice cup of tea and a sit down.)
When I came to run the binaries, I found they couldn't find Boost. Running this command fixes that:
Now we are going to install the packages which aren't already included in the default OS installation which the binaries need in order to run:
Place the bootstrap.dat file into the ~/.lore directory.
Run ./bitcoin-qt again, it will say 'Importing Blocks' rather than 'Synchronising with Network'. My pi sync'ed fully in about 5-6 hours.
If you want peace of mind that Lore will always start on bootup into the Jessie w/Pixel desktop (i.e. after a power cycle), then you need to create a .desktop file in the following place.
sudo nano ~/.config/autostart/Lore.desktop
And in it, enter the following (tailoring the Exec line below to the whereabouts of your bitcoin-qt file):
[Desktop Entry] Name=Blackcoin Lore Comment=Mining without the waste Exec=/home/pi/Downloads/lore-raspberrypi-armv7-jessie-pixel/bitcoin-qt Type=Application Encoding=UTF-8 Terminal=false Categories=None;
Power usage and payback time
After a good while leaving it going by itself, the CPU load averages got down to almost zero, all of the time. Idling, the Pi uses a bit less than 3 watts. This means it would take two weeks to use one 1Kw/h of electricity.
If you pay e.g. 12.5 cents a unit, that's what you'd expect this to cost to run in a fortnight. That's around $0.25 a month or $3 a year. Green and cheap and helping to secure the BLK network. I paid for the year's worth of electricity in 2 days staking with 25k BLK. Makes mining look silly, huh? ;)
Securing your Pi
With staking, your wallet needs to be unlocked and as such, the keys to your wallet are on the device. In a clean and newly installed environment as described above, and if you don't allow others to use your device and there is no other software or nasties running on it, there is no real cause for concern. However, there are some basic security precautions you can take.
Firstly, if you have enabled SSH and are playing with your pi across your LAN (or worse, the Internet), you should immediately change the password for the default 'pi' user (which is preconfigured to be 'raspberry'). Simply log in as normal, then type:
You'll be prompted to enter the old and the new passwords.
Security by default
Your Pi is likely, by default, to not be exposed to incoming connections from the outside world because your router is likely generating a private address range for your LAN (192.168.x.x or 10.0.x.x or 172.x.x.x) which means all incoming connections are effectively blocked at the router anyway unless you set up a 'port forward' record to allow packets arriving on certain ports to be forwarded to a specific internal IP address.
As for accessing your Pi across the internet, if you have set up a port forward, this likely has security ramifications. Even basic old fashioned protocols have proven in recent times to have uncaught flaws, so it's always advisable to lock down your device as much as possible, and even if you only plan to access the Pi over your LAN, install a firewall to configure this. I used one called ufw, because it's literally an uncomplicated firewall.
sudo apt-get install ufw sudo ufw allow from 192.168.0.0/16 to any port 22 sudo ufw --force enable
This allows just port 22 (SSH) to be open on the Pi to any device on my LAN's subnet (192.168.0.x). You can change the above to a single IP address if paranoid, or add several lines, if you want to lock it down to your LAN and a specific external static IP address (e.g. a VPN service you use). To find out what subnet your router uses, just type:
and you'll see on the interface you are using (either hard wired or wifi) the 192.168 or 10. or 172. prefix. Change the above rule so it matches the first two octets correctly (e.g. 10.0.0.0/16 if you're on a 10.0. address).
You may already use VNC to access your Pi's desktop across your LAN, this uses port 5900. Add a line like above to lock it down to an internal address. It's not a good idea to expose this port to the wider world because those connections are not encrypted and potentially could be subjected to a MITM attack.
You can query the status of the firewall like this:
And of course, try connecting remotely once you change the rules to see what works. You should consult the official documentation for further options: https://help.ubuntu.com/community/UFW
Back up & Recovery
There are again many ways to tackle this so I'll just speak about my basic precautions in this regard. Don't take it as a be-all-and-end-all!
The wallet.dat file is the key file (literally) containing all the private/public keys and transactions. This can be found in:
You can navigate there using Jessie w/Pixel's own file manager or in a terminal window (cd ~/.lore). You can copy this file or, if you'd rather keep a plain text file of all your public and private keys, use the 'dumpwallet' command in the console. In Lore, go to Help > Debug Window > Console and type 'dumpwallet myfilename' where myfilename is the file you want it to spit out with all your keys in it. This file will end up in the same place you launch bitcoin-qt from.
The instructions earlier on, when running Lore for the first time intentionally left out encrypting your wallet.dat file because in order for the wallet to stake upon startup, it needs to have a decrypted key already. This isn't perfect, but after a power cycle, it would never stake unless you left it decrypted. So the best practice here is as soon as the wallet.dat file has left your device, i.e. you copy it to a USB stick for example, put it in an encrypted folder or drive (or both).
On the Mac, I use a software package called Concealer to encrypt files I store on the Mac itself: http://www.belightsoft.com/products/conceale There are almost certainly free packages with similar functionality, I have just used that one for years.
Note that these disk encryption methods may mean having to access the USB stick on a PC or Mac in order to retrieve the files in the event of a disaster. Be aware this may mean exposing them to more security issues if your computer is in any way compromised or someone nefarious has access to your computer. There are more 'manual' ways of backing up and recovering, such as literally writing down private/public key pairs which this guide doesn't go into, but may suit you better if paranoid about your setup.
The wallet.dat file has everything in it you need to recover your wallet, or if you used 'dumpwallet', the file you saved out has all the keys.
Wallet.dat method: Install Lore as normal then replace any auto-generated wallet.dat in ~/.lore directory with your backup. If a lot of time has elapsed and many transactions have occurred since your backup, launch lore with:
And if that doesn't do the job, do a full reindex of the blockchain:
If you used the dumpwallet command, install Lore then place the file containing all the keys that you saved out in the same directory as bitcoin-qt. In Lore, go to Help > Debug Window > Console and type 'importwallet myfilename' where myfilename is that file containing all the keys. The wallet should automatically rescan for transactions at that point and you should be good to go.
There are a million ways to do effective security and disaster recovery, but I hope this shows you a couple of basic precautionary ways. There are discussions about better ways to stake without compromising too much security which are happening all the time and developments in this regard will happen in time.
In the meantime, feel free to comment with your best practices.
Reddcoin 2.0.0 is a complete rebuild based off Bitcoin 0.9. This means in terms of the code-base we have introduced all the Bitcoin changes up to and including v0.9.5 into this version of Reddcoin Core. Taking this path will allow faster adoption of critical fixes and features. Within this release we have also included some features from the 0.10 bitcoin build, including a connected peers tab and visual bandwidth monitoring We suggest to read the release notes of Bitcoin up to and including 0.9.5 to get a full understanding of the changes. On top of the new features, Reddcoin Core v2.0.0 update contains very important security fixes and all users MUST upgrade to this version as soon as possible. Details on several vulnerabilities were made public by the Bitcoin team (Official Bitcoin warning) regarding the issues. It is particularly important that users who are staking do upgrade. This release introduces BIP66, and version 4 blocks. Once BIP 66 is enforced, version 3 blocks will be rejected from the network entirely as they contain less secure transactions. This means, if you are staking, you need to upgrade so that you don't risk miss out on your staking rewards Details of other notable changes are posted on Github Releases
First, Backup your existing wallet.dat and data folder Where to find your Reddcoin data folder?
Free $10 - $xxx for anyone who has been using Bitcoin, Litecoin or Dogecoin since May.
Ok, this is a long and slightly technical post, so bear with me. So there is this new altcoin that has been going up in price pretty fast, it's called 'CLAM'. This coin is freely distributed. They're using a distribution method that gives you 4.6 CLAMs for each Bitcoin, Litecoin or Dogecoin address you have that had an unspent output on by May (it scans the blockchain for this, I believe). Instructions:
1 - Download the CLAM client from http://clamclient.com/#/download-clams/. Only download it from this location, others might be fakes. Google Chrome will probably tell you this is an untrusted download, so it won't even let you download this. This is common for altcoin wallets, and is a false positive. You can use Internet Explorer instead. I scanned the downloaded program afterwards and got nothing.
2 - Let the wallet sync. This might take a few hours. You can speed this up by using the bootstrap.dat file (pre-downloaded part of the blockchain). You can get this file and further instructions from here: https://bitcointalk.org/index.php?topic=623147.1480
3 - Import your BTC, LTC, and DOGE wallet.dat file into the CLAM client to recieve the coins. You'll have to enter the passwords to these wallets as well. I know, sounds sketchy as hell. If you're afraid that this will get your BTC, LTC or DOGE wallets stolen, you can move the funds on those wallets to new wallets, as the CLAMclient only looks for unspent balances on your wallet.dat file addresses as per May (so not as of today). Also, the code to this client is open-source, and there is nothing to suggest it steals your data, or does anything suspicious. Full instructions on how to claim coins by importing wallets: http://clamclient.com/#/import
4 - Now you have your CLAMs, you can sell them for Bitcoin on Poloniex (https://poloniex.com/exchange/btc_clam). There is no way to tell whether this coin will go up or down, so I just sold them immediately to be safe.
5 - Profit! (Optionally: sell your BTC for dollars.)
Currently this coin is trading at around 0.007 BTC, which is about $2.45. If you have one Bitcoin address that is 4.6*$2,45 = $11,27. If you have one BTC, LTC and DOGE address, you'll make about $33,81. If you have more computers you use cryptocurrencies on, and have multiple addresses for each wallet, you could make a couple of hundred dollars. Personally, I got 0.6 BTC, which is about $210, by doing this. Easiest money I've ever made on the internet :) Tips are appreciated! You can use one the following addresses: 1E5AADqAG6LjeXo6xaznoWT7ekbNGPa8wN (BTC) LVKaac2gpt5K41iqPgsg4KqaW4iUdhc3jj (LTC) DJxJtFTfTDLjVHk2t5TEL5ExDg4cgA3uq8 (DOGE)
Would be great if someone who has the skills & tools could generate us a nice stable MacOS build? Anyone?
Backup your wallet before using this. You've probably already done that, as I am sure you backup your wallet on a regular basis, right? Something bad happens, your wallet is destroyed AND you didn't take a backup? Don't blame me.
A lot of stuff has been renamed to 'Myriad' - however there are a couple of exceptions for reasons of compatibility with older existing versions:
default data directory is still myriadcoin
config file is still myriadcoin.conf
daemon is myriadcoind, rpc client is myriadcoin-cli
If you are compiling yourself, please configure with something like this:
That will enable the SSE2 version of the Scrypt algorithm. This may reduce the CPU load when syncing the blockchain. Oh, and there's still some tests that fail if you build and run the testsuite. I've been unable to find the issue, so please, when you fix it, submit a pull request.
A big thanks to cryptapus and 8bitcoder for their help in getting this release completed. Obviously we must also thank all of the contributors to the Bitcoin Core project, as that is the base that this is all built upon. And again thanks to 8bitcoder for starting Myriad in the first place.
Because this release is based on Bitcoin Core 0.10.0 and upwards, it makes use of headers-first synchronization and parallel block download (see further), the block files and databases are not backwards-compatible with older versions of Myriad Core or other software:
Blocks will be stored on disk out of order (in the order they are received, really), which makes it incompatible with some tools or other programs. Reindexing using earlier versions will also not work anymore as a result of this.
The block index database will now hold headers for which no block is stored on disk, which earlier versions won't support.
If you want to be able to downgrade smoothly, make a backup of your entire data directory. Without this your node will need start syncing (or importing from bootstrap.dat) anew afterwards. It is possible that the data from a completely synchronised 0.11.2 node may be usable in older versions as-is, but this is not supported and may break as soon as the older version attempts to reindex. This does not affect wallet forward or backward compatibility.
Notable changes (Borrowed from Bitcoin Core's Release Notes)
Myriad Core now uses 'headers-first synchronization'. This means that we first ask peers for block headers and validate those. In a second stage, when the headers have been discovered, we download the blocks. However, as we already know about the whole chain in advance, the blocks can be downloaded in parallel from all available peers. In practice, this means a much faster and more robust synchronization. On recent hardware with a decent network link, it can be as little as 3 hours for an initial full synchronization. You may notice a slower progress in the very first few minutes, when headers are still being fetched and verified, but it should gain speed afterwards. A few RPCs were added/updated as a result of this: - getblockchaininfo now returns the number of validated headers in addition to the number of validated blocks. - getpeerinfo lists both the number of blocks and headers we know we have in common with each peer. While synchronizing, the heights of the blocks that we have requested from peers (but haven't received yet) are also listed as 'inflight'. - A new RPC getchaintips lists all known branches of the block chain, including those we only have headers for.
RPC access control changes
Subnet matching for the purpose of access control is now done by matching the binary network address, instead of with string wildcard matching. For the user this means that -rpcallowip takes a subnet specification, which can be
a single IP address (e.g. 126.96.36.199 or fe80::0012:3456:789a:bcde)
a network/CIDR (e.g. 188.8.131.52/24 or fe80::0000/64)
a network/netmask (e.g. 184.108.40.206/255.255.255.0 or fe80::0012:3456:789a:bcde/ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff)
An arbitrary number of -rpcallow arguments can be given. An incoming connection will be accepted if its origin address matches one of them. For example:
0.9.x and before
-rpcallowip=::/0 (still dangerous!)
Using wildcards will result in the rule being rejected with the following error in debug.log:
Error: Invalid -rpcallowip subnet specification: *. Valid are a single IP (e.g. 220.127.116.11), a network/netmask (e.g. 18.104.22.168/255.255.255.0) or a network/CIDR (e.g. 22.214.171.124/24).
Watch-only wallet support
The wallet can now track transactions to and from wallets for which you know all addresses (or scripts), even without the private keys. This can be used to track payments without needing the private keys online on a possibly vulnerable system. In addition, it can help for (manual) construction of multisig transactions where you are only one of the signers. One new RPC, importaddress, is added which functions similarly to importprivkey, but instead takes an address or script (in hexadecimal) as argument. After using it, outputs credited to this address or script are considered to be received, and transactions consuming these outputs will be considered to be sent. The following RPCs have optional support for watch-only: getbalance, listreceivedbyaddress, listreceivedbyaccount, listtransactions, listaccounts, listsinceblock, gettransaction. See the RPC documentation for those methods for more information. Compared to using getrawtransaction, this mechanism does not require -txindex, scales better, integrates better with the wallet, and is compatible with future block chain pruning functionality. It does mean that all relevant addresses need to added to the wallet before the payment, though.
It has been observed that many of the RPC functions offered by myriadcoind are "pure functions", and operate independently of the myriadcoind wallet. This included many of the RPC "raw transaction" API functions, such as createrawtransaction. myriadcoin-tx is a newly introduced command line utility designed to enable easy manipulation of myriad transactions. A summary of its operation may be obtained via "myriadcoin-tx --help" Transactions may be created or signed in a manner similar to the RPC raw tx API. Transactions may be updated, deleting inputs or outputs, or appending new inputs and outputs. Custom scripts may be easily composed using a simple text notation, borrowed from the bitcoin test suite. This tool may be used for experimenting with new transaction types, signing multi-party transactions, and many other uses. Long term, the goal is to deprecate and remove "pure function" RPC API calls, as those do not require a server round-trip to execute.
Download the latest bootstrap.dat file to speed up the initialization process. Instead of loading and verifying each block from the peer-to-peer network, your Bitcoin client can load all this information from a single bootstrap.dat file. Import Blockchain With this bootstrap.dat file put under the data directory, when you start up Bitcoin-Qt, if bootstrap.dat file exists, it'll automatically start importing newer blocks (bootstrap.dat) into Bitcoin-Qt. During the import, Bitcoin-Qt verifies transaction signatures and the validity of past payments, and the blockchain files will be re-indexed. This process may still take hours ...
