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.

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)

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.
Understanding BIP149, redeployment of Segwit with BIP8
I recently published BIP149 and would like to take a few moments to explain the details of this proposal. BIP149 is a completely new deployment of segwit, which I propose if the current BIP9/BIP141/143/147 segwit deployment fails to lockin/activate by November 15th. BIP149 cannot be run on mainnet now, and there is code in the reference implementation to prevent it from running. It is incompatible with the current segwit deployment on purpose to remove unnecessary complications. Essentially, the idea is, if the current segwit deployment fails to activate by Nov 15th, we can release new software that has BIP149. This uses BIP8 to activate segwit by July 2018. Miners will still be able to trigger activation by 95% threshold signalling as normal. In the 8 months from November to July 2018, nodes will be able to upgrade to BIP149. If segwit is not MASF activated by July 2018, there will be enough of the economy running BIP149 that nodes can begin enforcement. What will actually happen is on the first retarget after July 4th, the BIP8 state machine will switch to LOCKED_IN status for two weeks, and then on the following retarget, ACTIVATION will occur. The rationale here is in 5 months we achieved 70% saturation of witness capable nodes, so by the time segwit timesout with all the urgency and demand people feel for segwit, we can expect them to upgrade at least as fast, if not much faster. I have spoken with a number of developers who think this is a reasonable assumption. Background, I had hoped to be able to release a BIP that can be deployed concurrently now with segwit, but, there are various technical complications in implementing it cleanly and making it easily reviewable. I had various feedback from others in previous iterations and in order to get the widest support from developers especially concerned with predictable results and thus safety, I came to the conclusion that the BIP will get the widest support by not attempting any shortcuts and by removing all complexity. I know many people want segwit now, but, I think we should just bite the bullet and do it the BIP149 way. I already made a shortcut BIP with BIP148. I will discuss the pros and cons at the end. Back to BIP149, this is a completely new redeployment with a new service bit NODE_UAWITNESS and new compact block protocol version - doing this avoids many gotchyas which I will explain below: Currently, segwit capable nodes advertize the NODE_WITNESS service bit and preferentially peer with other NODE_WITNESS nodes. Post activation, segwit-active nodes will then know who they should relay witness blocks to and who they should relay old style stripped blocks to. The assumption is if I am a NODE_WITNESS node and segwit has activated, then other NODE_WITNESS nodes will also be segwit activated. We cannot reuse NODE_WITNESS because when BIP149 activates, they would believe non-BIP149 NODE_WITNESS nodes were also active. Using a new service bit, and effectively starting a new deployment as if the previous deployment doesnt exist, is the most predictable and trouble free way to go about it. Additionally, BIP149 is compatible with existing mining software by reusing the "segwit" name and deployment chainparams (it's not possible to have two deployments with the same name, one expired and one pending/active, due to how versionbits is implemented). In short, if the current segwit deployment fails to activate, we can reuse parts to maintain compatibility, while changing the bare minimum to remove any conflicts with old nodes. It's clean, predictable and easy to review. BIP148 IS NOT BIP149 Remember BIP148 is exceptional, it's NOT what a usual UASF BIP should look like. A normal UASF if effectively activation on a predetermined date in the future (a flag day). BIP8 combines BIP9 miner signalling with a flagday if MASF does not occur. How is BIP149 different to BIP148? So BIP148 is a UASF which can be used in two ways. (a) The economy can run BIP148 and basically force miners to signal for segwit, thus activating the current segwit deployment. Or, (b) a majority of miners, 60% or so, could run it and censor other miners who do not signal segwit, thus causing the current segwit to deploy. In method (a) a chain split will occur if any miners do not upgrade, and given the fact there are always absentee miners and pool operators, this is quite likely. It's the economy vs hash power saying "if you dont signal, your blocks will not be worth anything because we will reject them". In the case of (b) you have a majority of hashpower, who could use their majority to orphan any non signalling miners. This isn't great but it's less disruptive than (a) because there is a majority hashpower definitely opted in. BIP149 on the other had does not guarantee a chain split since that could only happen if a miner deliberately takes action to manually create a segwit invalid block, which would be rejected by the economy. The incentives are different also, with BIP148 a chainsplit comes for free, regardless of if it lasts long or not. In BIP149, a miner would have to specifically take action to split and waste their money, which they could do at any time anyway. BIP149 is uncontroversial in the sense it is just a redeployment with guaranteed activation at the end, for a soft fork we are fairly sure people want and will upgrade to. The evidence is everywhere. UASFs deployed over a long time and a decent flagday are perfectly safe - all soft forks are enforced by nodes, even if activation is triggered by hashpower. Anyway, we've got 8 months from now to review and think about BIP149 - it cannot be deployed until November. If you would like to show support for BIP149, feel free to add the following to your bitcoin.conf
You can find the bitcoin.conf file here You can also just add this to a shortcut - create a shortcut (or edit the existing one you use) and add this to the end: -uacomment=UASF-SegWit-BIP149 e.g. (just add the property to the end like this): "C:\Program Files\Bitcoin\bitcoin-qt.exe" -uacomment=UASF-SegWit-BIP149 if you are using Windows. You can also just add uacomments as multiple command line/shortcut arguments like
how to shibecoin v rich in minutes much instruct so simple any doge can do
UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions. Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client. Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots). If you've waited 2 or 3 minutes and nothing is happening, copy this:
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
On Windows this is C:\Users\[YOUR_USER]\AppData\Roaming\DogeCoin
On Macs it's ~/Library/Application Support/DogeCoin
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes. Once it finished downloading, you're ready to send and receive Dogecoins!
Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.
Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.
These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.
Step One: Choose a pool
There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later. NOTE: Youcanmineintwoways.Solominingiswhereyouminebyyourself.Whenyoufindablockyougetallthereward.Poolminingiswhenyouteamupwithotherminerstoworkonthesameblocktogether.Thismakesitmorelikelythatyou'llfindablock,butyouwon'tgetallofit,you'llhavetosplititupwithothersaccordingtoyourshareofthework.Poolminingisrecommendedbecauseitgivesyoufrequentpayouts,becauseyoufindmoreblocks.Thelargerthepoolyoujoin,themorefrequentthepayouts,butthesmallertherewardyouget. Overalongperiodoftimethedifferencebetweenpoolandsolomininggoesaway,butifyousolomineitmightbemonthsbeforeyougetanycoins.
Step two: Set up pool account
The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
Create an account
Create a worker under the account
Grab the mining URL (usually on the getting started page)
Setup your cash out options in your account settings by entering one of your wallet's receiving addresses
When you're done with this, you'll need to know:
Your account, worker name, and worker password
The mining (stratum) URL (usually the pool's URL followed by a port)
Step three: Download mining software
For best performance you'll need the right mining software.
Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets). For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p For Nvidia it's cudaminer.exe -o stratum+tcp://: -O : Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.
Step five: Launch your miner
Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate. If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough. NOTE: Anormalhashrateisbetween50Kh/suptoeven1Mh/sdependingonyourGPU.
You're now mining Dogecoins
That's it, nothing more to it.
CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.
Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:
Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!
This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.
Other redditors can give you Dogecoin by summoning the tip bot, something like this: +dogetipbot 5 doge This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff. As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one. If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.

Run a 0.14 Full-Node on RaspberryPi3 Pruned(less than 16GB SD needed)
Hi! Happy if this guide helps you. Tip if you want: 19656Uwdwko5RjtnuwQENpjBwE3ChzD59v UPDATE 04/06/17 Add 'uacomment=UASF-SegWit-BIP148' into your bitcoin.conf if you want to signal UASF. UPDATE 03/13/17 ADDED a tl;dr; Version at the end of this Post. UPDATE 03/12/17: Just to test it - I reinstalled all on 8GB SD and it works as well. But maybe you should use at least 16GB for the beginning. Using a 128GB card for the first version was a little bit stupid - so I reinstalled everything on a 8GB SD card. Including Linux and a pruned blockchain - and it works. I used prune=550 and Jessie Lite (headless / command line) - without wallet and gui. The SD is almost full, but it works so far I also updated the whole manual a bit to make things more clear. Thank you for all your feedback! Just started my Bitcoin Node today and wanted to share the way I did it with people who are interested in running their own full node. It took some time to write everything down - hopefully correct so far. I am sure, many people around bitcoin are way more informed and educated as I am - I am the noob. So I wrote this manual to help users like me - noobs, to get started with a cheap, simple bitcoin node on raspberry pi. Have fun! I wanted to get my Raspberry Pi 3 working as a node to support the network. Actually the process of installing and running the node was more or less easy - but for Noobs (like I am) it might be a bit tricky to start the whole thing, because there are different ways. Did you - like me - think you would need +120GB on the raspi, external USB HDD to be a full node? You won't! If you have a Raspberry and you know what Bitcoin is, I guess, you are a little bit aware of linux, networks and of course bitcoin - so I won't go into detail too much. This guide is just a little helper to get a full node running on your raspberry pi. Thanks to the help of the nice people in this sub and of course the documentation by the developers, I got it working - and of course also special thanks to raspnode.com - as I followed their tutorial to start - I went some other ways here and there - so please read carefully. For the Part 2 I would suggest to have http://raspnode.com/diyBitcoin.html open and read through my manual. I split the tutorial in 2 Parts - PART ONE is about installing the client on your PC and downloading the Blockchain. PART TWO is about the setup of the raspberryPi and transferring the pruned blockchain to the pi and run it as a full node! The first thing to be aware of is: You actually need to download the whole blockchain to get this working - if you already have your bitcoin client synced on the PC / MAC great you can reuse it! Now you might think "but you said less than 16GB in the title!" Yes, but the good thing is you won't need to download it on your Raspberry, neither you need to sync it completely on your raspberry which took ages (weeks!) before. When you finished this Guide, you will just have a max. 4GB Blockchain on your Raspberry Pi - but it still is a full node! The magic word is Pruning. Maybe even a 8GB SD Card works just fine including Linux (jessie lite)! So, if you already have a full node on your PC - Great you can almost skip PART ONE - BUT have at how to Prune in PART ONE if you don't know about it. For PART TWO you'll need a Raspberry Pi 2 or 3 (I used 3) min. 8GB (works also) or better 16GB SD Card. (I used a 128GB for the first version of this manual - which is way too big)
This is the manual how to get started on you PC / MAC / Linux (I did it on Win7) Go to: https://bitcoin.org/en/download and download the core Client for your Machine (I used win64). Install it and configure it to save the Blockchaindata to the directory of your choice - so instead getting 120GB on your C drive, I would suggest to download it to another place like a USB drive. You can set this up during the install. Standard folder for the blockchain folder is "%APPDATA%\Bitcoin" on Windows. or you can do it after the install by creating a bitcoin.conf file inside your installation folder / or %APPDATA%\Bitcoin and add
to the file. Line by line. By the way here you could also just add dbcache - to use more memory to speed up the process a bit:
if you don't want to use the settings inside the program. (you can also set this inside the program under settings! If you have this inside the bitcoin.conf you will see the amount you set there from inside the program - it overrides the values) You can check inside the windows client under settings, if you can see a manual dbcache is set by having a look at the left footer area. When your dbcache value shows up, everything is fine. So the Blockchain download process will take time - maybe a few days! Depending on your machine, internet connection and HDD. The Blockchain is huge as it contains every single transaction of the past until today. You won't need to keep your PC running all the time, you can turn it off and on and it will resync automatically when you start bitcoin-qt.exe! Make sure to close the client always via "quit" - ctrl+q. After you have your bitcoin core installed, the blockchain downloaded and synced - you are ready to PRUNE! First - close the Client and let it close smoothly. After it is really closed you can follow these steps:
By pruning, your blockchain will dramatically shrink. From 120GB to just a few GB.
Be aware, that you will lose your Downloaded Blockchain as pruning will erase a big chunk of it! If you have enough space, you could of course keep the full blockchain saved somewhere on another HDD. You can prune by editing your bitcoin.conf file by adding:
I used prune=1024 - not sure where the differences are right now (min. prune=550). (for my 8GB version I used 550! I suggest to use this.) Save the bitcoind.conf file and restart your windows client. It will now clean up the Blockchain. So just the latest blocks are saved. The client should start without any problems. Maybe it takes some time to prune the blockchain data. Check if everything works normally (the client opens as usual, you can see an empty wallet) than close the client. Inside the Bitcoin Folder, you'll find two folders called:
those are the interesting folders containing the important data (now pruned) - and we will transfer those two to the raspberry later! Now you are good to start the raspi transfer explained in the next part.
Here is what I did: 1) I installed Raspian Pixel (https://www.raspberrypi.org/downloads/raspbian/) using a 128 GB SD - which is not needed because of "Pruning" - I think a 16GB card might work, too! (You can also install Raspian Jessie Lite - which saves you even more space, as it runs headless - only command line) (Updated: It is better to use Jessie Lite to save a lot of space - when you are fine with only command line) 2) I followed partly this tutorial to get everything running and setup:
Please have a look at it - I have copied the Headlines in capitals to let you know what I did, and what I skipped. On Tutorial Page: Start with RASPBIAN (OPTIONAL) CONFIG OPTIONS. Set You RasPi up including "EDITING FILES" to save your Layout at the tutorial page and come back here. I skipped the CONFIGURE USB AND SET AUTOMOUNT process, as we are going to use PRUNING to reduce the 120GB to a tiny filesize - so USB Devices are not needed here! It was necessary to ENLARGE SWAP FILE to install bitcoin core - otherwise it didn't went through which ended in a frozen raspi. So have a close look by following the raspnode tutorial at: ENLARGE SWAP FILE. I have my raspi running via cable to router - but you can also WiFi setup everything described under NETWORKING ON THE RASPBERRY PI. Now comes the interesting part: Follow the steps at DOWNLOADING BITCOIN CORE DEPENDENCIES - they work fine for 0.14.0 too. Git should be on Board already when you installed Pixel - otherwise you would need to install it.
sudo apt-get install git -y (only jessy lite)
I skipped the next command lines - as I don't use bitcoin-qt wallet. If you want to use it as wallet - do the step.
as I don't need the wallet functionality. I didn't need to use "MAKE" which saves you maybe up to 2.5 hours. instead you can just go ahead with:
sudo make install
(If I am wrong in doing so - please let me know) The install takes some time - and just a heads up: when it gets stuck somewhere - just redo the installation process - it took three times to went through - stuck at some processing. After the installation took place you can finally get your Raspberry Pi Node running in no time! To test if the the installation went through - you can just start bitcoind using:
than check if everything is working so far:
after a few seconds you should see version: etc... if not, something went wrong. Try to redo the steps in the raspnode tutorial. (don't give up if it failed - retry! Ask your questions here) IMPORTANT: you need to stop bitcoin on your raspberry now!
If you don't need an external USB Drive - what I hope - as we are going to use pruning just go ahead and skip the USB part and create a file inside (or follow the raspnode tutorial on how to setup the USB drive):
cd .bitcoin sudo nano bitcoin.conf
and enter the exact same pruning size you have used on your Desktop Machine to prune. I used 1024 but the minimum is 550. (used 550 for the 8GB SD card on PC and Raspberry)
That's it for the raspi. update: To signal UASF enter in a new line:
Now you have to transfer the two folders CHAINSTATE and BLOCKS from your PC bitcoind directory to your raspberry. I am using a program called "WINSCP" - it is free and easy to use: https://winscp.net/eng/download.php We need this to transfer the files to the Raspberry pi. Pretty sure you can also do it via SSH - but I am the noob. So let's keep it simple. Open Winscp and put in the IP Address of your Raspberry Pi, User and Password (same as in SSH) You should now see the directories on your Raspberry Pi. There is a folder called
enter it and you will see the two folders
blocks & chainstate
you can delete them on the raspberry as they have some data from your previous test inside. Make sure you can also see the bitcoin.conf file in that directory, which needs to contain the exact same prune line, like the one on your desktop machine. If not, make sure to edit it via SSH. The line "datadir=l:\yourfolder" is obviously not needed in the Raspberry bitcoin.conf file. Now grab the two folders CHAINSTATE and BLOCKS from your PC and copy them to your .bitcoind folder. I also copied banlist.dat, fee_estimation.dat, mempool.dat and peers.dat to the folder - not really knowing if needed! Not needed. The whole copy process might take some minutes (against some weeks in the old way). After copying is finished, you can now start bitcoind on the Raspberry.
the & symbol let you still use the command line while the process is running btw. The process - if succesfull - will take some time to finish.
Will give you some informations what is going on right now. When you can see, that it is checking the blocks, this is good! If you get an error - double check - if you have the correct prune size (same as on desktop machine) - in bitcoin.conf and that this file is inside .bitcoin on RaspberryPi. It took me some time, to find my mistakes. Congrats! You are almost a part of the network! To make your node now a fullnode, you will need to go to your router (often 192.168.1.1) and enable portforwarding for your raspberry pi - and open ports 8333 - that's it! You can now go to: https://bitnodes.21.co/nodes/ scroll down to "JOIN THE NETWORK" and check check if your node IP is connected! It will show up as soon as the blocks are checked and the raspi is running. Well done! Now you are running a full node, with a small Blockchain and got it working in Minutes, not weeks! I really hope, my little tutorial worked for you and your are part of the Node network now. If you have problems or I made a mistake in this helper tut, just let me know and I will try to make it better. Have fun and NODL! the noob tl;dr; (if you are a real noob start with the non-tl;dr version!) tl;dr; PART ONE 1) Download & install / setup bitcoincore @ https://bitcoin.org/de/download 2) change dbcache to something smaller than your memory and download the whole Blockchain (120GB). 3) create a file called bitcoin.conf put the line prune=550 (or higher) in to activate pruning on win inside %appData%/bitcoin 4) Open ports 8333 on your Router to make this a full node with a smaller Blockchain. You are running a full node on your PC. tl;dr; PART TWO 1) Install jessie lite and the needed dependencies on your SDCard - Raspberry ( >git clone -b 0.14 https://github.com/bitcoin/bitcoin.git )
see tutorial for more info.
2) create a file called bitcoin.conf inside .bitcoin and add the same prune=Number you had on your PC. 3) transfer the pruned folders BLOCKS and CHAINSTATE to the Raspberry Folder .bitcoin 4)Start "bitcoind &" 5) let everything sync 6) Make sure you have port 8333 opened on your router. You are running a full node on your Raspberry with a super small Blockchain (I put all on a 8GB SDcard) Tip if you want : 19656Uwdwko5RjtnuwQENpjBwE3ChzD59v updated 03/12 - will update more, soon. updated 03/12.2 - I updated the whole process a bit and also added some improvements. updated 03/14/ Added a tl;dr version at the end.

The pool holds onto your coins, go to "Account" >> "Withdraw" to withdraw your coins In your BiblePay Wallet go to "File" >> "Receiving Address" and you can right click and copy the address and paste it into the Pool's Withdraw screen as the "Destination Address", then click the "Withdraw" button and the coins will be sent from the Pool to your Wallet Setup Auto-Withdraw Navigate to Account >>> Account Settings >>> Verify your BBP Receiving Address >>> Click Authorize-Auto-Withdraws Why use a Pool? As the network hash rises (as more miners are mining), it can take longer and longer to solve a block, by using the pool, everyone works together with all of their hash power to solve blocks, and the reward gets split between everyone who contributed based on how much they contributed in hash. With solo mining (not using the pool) it may take 1 month to finally solve a block and get large BBP reward, with pool you can get small frequent BBP rewards every ~30 minutes. (BBP meaning BiblePay coins) How to Update: Download exe from biblepay.org and install again, your wallet will stay intact Backup: Your wallet.dat stores your private keys that contain the access to your coins, this file is backed up every 24 hours in the backups folder, We also recommend that you save a copy of this file in other places, like a flash drive Learn More about Backing Up your Wallet.dat https://www.reddit.com/BiblePay/comments/7lksp4/backup_walletdat/ FAQ QUESTION: How long does it take for coins to mature?

WARNING: A fake electrum website with malware is advertising on duckduckgo and yahoo.
If you perform a search for electrum on duckduckgo or yahoo, an ad claiming to be electrum.org will be at the top. In reality the ad links to: electrum-bitcoin org The domain was created December 21. This site is nearly identical to electrum.org except the download links give different files. All three of the files that can be download are much smaller than the real electrum and are most likely malware. The three files are: electrum.exe - 91136 bytes electrum.out - 60316 bytes electrum.zip - 32478 bytes EDIT: Some Advice: When installing software, especially something as import as wallet software, it is a good idea to verify the integrity of the download with a signature using a key that was obtained from one or more seperate sources. I made a list of the keys used to sign popular bitcoin wallets below to act as another source to verify the integrity of those keys. Bitcoin-Qt: Signer: Gavin Andresen [email protected] Fingerprint: 2664 6D99 CBAE C9B8 1982 EF60 29D9 EE6B 1FC7 30C1 Key ID: 1FC730C1 Key Link: bitcoin.org/gavinandresen.asc Electrum: Signer: ThomasV [email protected] Fingerprint: 6694 D8DE 7BE8 EE56 31BE D950 2BD5 824B 7F94 70E6 Key ID: 7F9470E6 Keyserver: pool.sks-keyservers.net Multibit: Signer: Jim Burton (multibit.org developer) [email protected] Fingerprint: 299C 423C 672F 47F4 756A 6BA4 C197 2AED 79F7 C572 Key ID: 79F7C572 Keyserver: pgp.mit.edu Armory: Signer: Alan C.

EDIT: GPG Examples: Verifying Bitcoin-Qt: First download, import and check Gavin's key: Download his key at bitcoin.org/gavinandresen.asc In terminal or command line run:
gpg --import gavinandresen.asc gpg --fingerprint
Check that the fingerprint for Gavin's key matches 01CD F462 7A3B 88AA E4A5 71C8 7588 242F BE38 D3A8. Then download the wallet software and signature. Verify the signature:
gpg --verify SHA256SUMS.asc
You should see:
gpg: Good signature from "Gavin Andresen (CODE SIGNING KEY) "
The signature for Bitcoin-Qt signs the hash values. So we must compute the hash of the downloaded software. This example is using the linux version.
gpg --print-md SHA256 bitcoin-0.8.6-linux.tar.gz
Check that the output matches the associated hash value in SHA256SUMS.asc Verifying Electrum: First download, import and check ThomasV's key: This key can be found at a keyserver.
WHAT IS A DOGE VANITY ADDRESS Vanity addresses are ones where you can choose what characters appear somewhere in the address. For example, DPie5ucpypDTUsgquc3ea2Meg6TwpW6mW1. All Doge addresses must start with D (capital) and the second character must be a capital if it is a letter (not all letters accepted, for example I O Y W are not allowed as the second character). You can also create letters or words at the end or even beginning of the address such as:
Letters that I have found valid as second characters are: 5 6 7 8 9 A B C D E F G H J K L M N P Q R S T U HOW TO CREATE YOUR VERY OWN DOGE VANITY ADDRESS
Unzip it to a folder you can easily access via command line (c:\vanity is a good example)
Launch “Command Prompt” and go to that folder (“cd c:\vanity” if you chose that folder)
Choose the generator you will use. Use “vanitygen.exe” or “vanitygen64.exe” for CPU gen or “oclvanitygen.exe” for OpenCL devices Command will be one of the following (replace Doge with what you want to generate)
oclvanitygen.exe -X 30 -p 0 DDoge (you may need to change “-p 0″ to “-p 1″
vanitygen64.exe -X 30 DDoge (Use this if the above command does not find a valid GPU)
This will continue searching through the chain until it finds a privatekey that signs an address beginning with DWord
Once one is found, it will show you the Address and the Private Key (read below on how to import)
You can use “-k” to “keep searching after a match and “-r” to accept regex (useful for finding a suffix instead of a prefix)
You can direct the output to a text file with “-o filename.txt”
You can have it read a list of different terms from a file using “-f list.txt”
If you get an error that states Bitcoin addresses can only start with a “1″, then that means your second character is invalid. Make sure it is an UPPERCASE character and if that does not work, try a different character. Again, O I Y W are not allowed for second characters. If the error states that a specific letters such as “O”, “I” or “L” is not allowed you can try using a lowercase version of it.
HOW TO IMPORT YOUR NEW DOGE VANITY ADDRESS INTO YOUR DOGECOIN-QT WALLET
You need to save the Privatekey from above to use the address.
Open your Dogecoin wallet client if its not open already.
Go to Help > Debug Window > Console
If your wallet is encrypted and locked, type in: walletpassphrase “YOURPASSWORD” [seconds to stay unlocked]
Now type in: importprivkey “TheVeryLongPrivateKeyThatYouReceivedFromTheLastStep” “A nickname for this wallet”
You should see the command be accepted, and it will stay processing the key for 5-60s
You will see another line with no text show when complete. The icon will have red text on it vs the green text that your commands icon had. Once you are done importing all of your privatekeys into the client, you will need to restart it to see them in your list.
"Quick update on State of The Biblepay, and a request for any constructive criticism on a potential new idea. So before I share the new idea I want to say I am committed to adding new Gospel features to BiblePay. I dont want to give the impression that we are moving away from core values or anything like that. I feel like our Dev Team that is forming behind the scenes now will be able to continue to maintain and enhance the wallet and the pool with more features to spread the Gospel. We do need to continue searching and implementing ways on spreading the Gospel to IT Geeks, as we need to be true to God and practice what we preach, in that since He commands us to feed his sheep (as we help the orphans) and spread his word, we can do this at the same time by enhancing the wallet. Next, I want to explain some background. Ive been following Stratis for certain technical reasons over the last year and for a while I didnt think Stratis would affect BiblePay, but now I have reason to think it might be able to complement BiblePay if we complement Stratis. I was a corporate programmer for about 20 years and ended up programming in c# before I started a data company that has a product that is written in c#. So I do have a propensity to "understand" the architecture that built Stratis. Stratis is a rewritten blockchain infrastructure built from scratch in c#. Everything is there, the database, the hash function, the sha function, the blockindex, the syncing, everything. What Stratis does not have yet: No altcoins run stratis because the UI is still in its infancy, its a Web UI called Breeze. Also, they just finished writing POS a couple weeks ago so really no one was mining stratis except - in the stratis-berkeleydb-qt wallet using POW. Anyway the reason I mention Stratis, is I think it would be interesting if we were the first Altcoin to run a Stratis fork. I was thinking, I have the team behind the scenes that could potentially port Stratis into Biblepay and Biblepay into Stratis, and we could write a new C# UI, one that is not web based (that would be Windows native forms based as an EXE download). So our contribution to Crypto in this case is we would check-in the ability to run a stratis back-end on an altcoin with a Windows native UI (IE that is biblepays contribution). The Second contribution would be adding PoBH (our hash class), and the Third would be adding Dash masternodes To the Stratis core. So another words, we would have a native windows wallet download with masternodes, a new UI, and full sync-compatibility with the existing Biblepay wallet and keys.... I would estimate this project "could" potentially make BiblePays marketcap worth at least $100MM. (As Stratis is $795MM). It also gives us SegWit (which we have a quote request out for), allowing us to run Lightning Network in the future. Its an exciting project, that I think devs would want to jump in and help us with also- as I know the c# corporate workplace is very deep- and that could ensure our long term stability as well. I truly think this project could be done along side our normal Gospel enhancements, in a safe way. (Safe as in parallel until the Stratis wallet works). We basically would release a windows wallet that would sync in a compatible manner to the Berkeley wallet, and offer a separate download. If this project took off, we could refocus our support into the c# wallet and find a way to port the c# to mono, and stop developing berkeleys wallet (to have one codebase in the future). It does offer an interesting perspective, to support one codebase that is potentially c# in the future. And finally this idea opens up one more huge market for us that is harder on the berkeleydb side: Stratis smart contracts. Stratis is working on that, and I feel our future full dev team can integrate smart contracts into the stratis code, contracts that are more efficient. Ones that offer consensus based on c# code (instead of the bitcoin main chain), and - possibly, smart contracts that execute actual c# language code (meaning they could be very complicated contracts). The primary reason I write all this is to invite any constructive criticism on the idea. No I dont want to hear from people who do not know what they are talking about (for example, miner comments like Oh you are going to push us off linux, and kill us? ) Im talking technical and bitcoin and high level comments for this idea." -Rob "Dash will release the Evolution upgrade soon with Dapi and much more. Dash is the future. I think BiblePay should stay with the Dash business model and update the codebase as dash core release Evolution version. Unless you have a way to keep the dash core business model and ADD Stratis features. That would be great. Also, FYI, there is already a Stratis fork name Obsidian." -Samoshi "Thanks! Didnt know about Obsidian. I see all kinds of Stratis talk in their ANN. Their whitepaper is missing. Looking at their wallet pics it looks like they modified breeze. To include instant messaging. Thats the stratis web UI I was referring to - I think we would gain traction if we had a UI that looked like our QT that ran in windows natively with stratis. I synced stratis a couple months ago using source against bitcoin and it syncs very fast. I believe because the database is using NoSql which is apparently pretty good. It looks like flat files on the drive. Anyway, yes, I have evolution downloaded and running here. (Our other team needed to dissect it for their current project). So far it doesnt add anything to our needs for orphan payments, but I agree, we need to stay on top of potentially pushing new features back into biblepay. It does not include SegWit, so we really gain nothing by monkeying with the latest evolution check in at least for a little while. But to address your question about masternodes: I fully promise we will stick to our roadmap, and deploy our masternodes and let our integrity rise and hopefully our price as more users buy to lease masternodes, and we embrace them. For stratis, Im thinking about potentially running a stratis biblepay clone in parallel, one that is compatible with our chain, and porting the masternode (sanctuary) features Into the stratis clone to make that clone compatible with biblepay. If all went well theoretically, I was thinking (especially if our price was rising) about offering a second flavor of masternode in c#. One extra type of lease to run .NET code. (Thats just a concept for now)." -Rob Is this news from Stratis relevant? https://stratisplatform.com/2017/12/08/masternode_mainnet_beta_release/ That should help a lot. The good news is the UI does not appear to exist anywhere (other than that breeze web UI), so Im trying to do something slightly pioneering. On an interesting side note, all of stratis c# is written in the new cross-platform .NET "Standard core" version 2.0 (the one that was not written by microsoft), so the daemon actually runs on linux (and v2.0 does not have a UI for Windows). However, .NET 4.7.1 (with windows.forms UI) runs on windows, so putting a UI on it means it runs in windows and not linux. (We can look at mono on that later) but Im more concerned about writing a proof of concept now to see how it works. Conceptually a linux user would have biblepayd, the ability to mine in linux, and run from the command line. Windows would have the UI. Then we would have our nix programmers port the UI to mono. There would be no QT version (LOL). Very interesting. -Rob "I took a look at Obsidian, and Im happy to say that so far it is actually a port of Stratis with the Obsidian-QT wallet - meaning it does not yet include any Prod c# code, or c# UI. The UI in the Obsidian-QT wallet is the same as our Biblepay-QT wallet (minus the masternodes). The thing they are releasing at Christmas is messaging for Android - not c# web UI either. Thats good because that means we have a wide open space to do something pioneering with Stratis still. We might not be the first as this is a HUGE project. I think it will take a quarter to release a proof of concept. But its good to know we might be able to focus on this project for something very original and bright for BiblePay. I was thinking of a huge potential side effect we might inherit if we ever have a c# wallet. We could literally add hundreds of gospel features in the wallet without breaking compatibility with a very quick release schedule as the codebase would be pool compatible, and in addition we could add tons of windows forms features to the code." -Rob References: https://bitcointalk.org/index.php?topic=2388064.msg25800699#msg25800699https://bitcointalk.org/index.php?topic=2388064.msg25810636#msg25810636https://bitcointalk.org/index.php?topic=2388064.msg25818256#msg25818256
I have previously suggested that one way to get more people to run full nodes would be to make it so that the client only forwards transactions at night. This could be a good option for people who would like to run a full node, but who find that it negatively impacts their internet or PC performance. Some people responded suggesting I write a patch. I don't have the skill set to do that, however, I did research how to schedule tasks from the Windows command line, and wanted to share. To run a (windows) full node all the time, but only upload at night, you can type the following commands:
This will restrict the node to 8 peers during the day, allowing you to receive new blocks while consuming minimum resources. At night, the node will connect to up to 125 peers. You could use this to set up more complicated schedules -- for example run without restricting connections when you are asleep and when you are at work. You can either type these commands in the windows command line, or you can drop them into a batch file and run it. (Create a text file and save it with the .bat extension to create a runnable batch file. Careful with using Notepad, which will sneak in a hidden .txt extension unless you set the save file type to all files instead of text files.) Schtasks does not support waking the computer up from sleep. If you want your computer to wake up, you will need to use the Control Panel to create the scheduled tasks. :-( It's not too hard, but putting the above lines in a batch file is easier. If you want your computer to fall asleep after it finishes node-work, you can use something like this:
...to wake the computer, and then have bitcoin start up a few minutes later. It did not work for me when I tried to set up a task to start bitcoin and wake the computer at the same time. Obviously the more time your node can spend relaying blocks and transactions the better, but this option might get some people who are on the fence to start running a reachable node. Remember to open port 8333! If you are using a typical setup, this could mean that you need to:
Configure your router to assign your computer a static ip address
Configure your router to forward port 8333 to that ip address
Go to windows firewall and open port 8333
More help I think the "on at night" feature would be helpful to have standard in Bitcoin Core to encourage altruistic nodes. Other improvements I would like to see to help boost the number of running full nodes:
Data cap of some kind. For example, there could be the option to set a daily data cap -- after which the client will receive blocks but will not transmit them.
More wallets options that use Core. For example, it would be nice if you could get a version of Electrum that communicates with your running full node. I have nothing but respect for the Core devs, who are advancing the state of the art, but there is no mystery why people are using Electrum instead of Bitcoin Core for their wallet.
A wallet on your phone that could pair with your home full node. That way your phone would not have to leak any information to listening full nodes, and also you would have full validation whenever anyone sent you coins.
A clearly visible message that notifies the user that port 8333 is closed and tells them that they are not contributing to the network. Instructions on how to open port 8333.
For many of us, running a full node would have negligible cost. Even if we may not need them, having thousands of independent, reachable nodes inspires confidence in the Bitcoin network and rebuts the specious but often heard argument that full nodes are declining and therefore Bitcoin is doomed. If you are interested in the success of Bitcoin, please show your support by running a full node. If you prefer not to run it all the time, consider running it just at night.
I posted about this a while ago and the consensus was "just wait, it'll go through" however its been two months now and it still hasn't. Yes, I was an idiot for not putting a TX fee, but now I just want to figure out how to recover this coin. Any help would be greatly appreciated! The transaction never got posted to the network, so it looks like no one ever relayed it. If I search for the TX id, it doesn't show. I tried to install Pywallet but it wasn't installing and the help forums didn't really provide any help.

I opened the "C:/Program Files/Bitcoin" folder at the command line (shift + right click it) and was able to type bitcoin-qt.exe -rescan. Will report back when that's done EDIT2: Rescan didn't work. Will try exporting the private key into a blockchain.info wallet next EDIT3: I was able to export the private keys into a blockchain.info wallet and have sent the coin over to my phone!

Hi All, Running Windows 8 64-bit, Armory v0.9.32-beta-85959b20d8, Core Bitcoin v0.10.2. Armory loads up just fine, and using Process Explorer (Sysinternals tool), I am able to see ArmoryQT.exe as the parent thread with bitcoind.exe as one child thread (which has a conhost.exe child thread) and another child thread for guardian.exe (which also has a conhost.exe child thread) This is how it looks:
Now, as soon as I load Armory, the wallet consistency check passes and then it's stuck in "Initializing Bitcoin Engine" with no progress at all (just the rotating grey/green wheel) - then about 15 minutes later, I'll notice that the bitcoind.exe process and its child disappear. Guardian.exe is still running though. Now, when I disabled Armory from controlling bitcoin, I can load Bitcoin-Qt.exe no problems, it syncs with the blockchain no issues, and Armory will phase in and out of being connected. Which is totally weird....like the rpc connection somehow gets lost and reconnects at random times. But, even when Armory shows it's connected, and Bitcoin-Qt.exe shows that's it's fully synced with the blockchain, it doesn't update any transaction info in Armory at all. Now, I can see in the blockchain that my last few transactions already have 38 confirmations, but Armory still shows that there are 0 confirmations and that the transaction hasn't hit the blockchain yet. Obviously this isn't true. So, I turn to y'all for some help and guidance....I've scoured their forums, and I've tried all the suggestions, so I'm turning now to the trusted reddit community for some insight and help. Any ideas?! I mean, I could probably just backup my wallet, uninstall both armory and bitcoin, then do a clean install, then wait a month for the blockchain to sync, but I'd prefer to have to avoid this if that's AT ALL possible. Also, not sure if this is relevant, but even though the blockchain is synced, shortly before bitcoind.exe goes out of commission (only when run through Armory, bitcoin never crashes when loaded separately) the cpu % for that process spikes to about 45-70% for a few minutes, which sounds like it's processing headers and what not, and then just poops out. I have a quad-core AMD A6-3600 - not the BEST but not the worst either.... Ok, help....please.... EDIT: formatting

I've seen this asked about the Bitcoin QT client itself, but what about letting Armory run it? Since you need to point it at the daemon folder to allow Armory to run it, it seems to use the bitcoind engine executable alone instead of messing with the client UI, so changing the command line parameters on the QT exe wouldn't have an impact. Is there a similar step to be taken on the bitcoind exe to achieve this?
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), uninstall all earlier versions of Bitcoin, then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux). If you are upgrading from version 0.7.2 or earlier, the first time you run 0.9.0 your blockchain files will be re-indexed, which will take anywhere from 30 minutes to several hours, depending on the speed of your machine. On Windows, do not forget to uninstall all earlier versions of the Bitcoin client first, especially if you are switching to the 64-bit version.
Windows 64-bit installer
New in 0.9.0 is the Windows 64-bit version of the client. There have been frequent reports of users running out of virtual memory on 32-bit systems during the initial sync. Because of this it is recommended to install the 64-bit version if your system supports it. NOTE: Release candidate 2 Windows binaries are not code-signed; use PGP and the SHA256SUMS.asc file to make sure your binaries are correct. In the final 0.9.0 release, Windows setup.exe binaries will be code-signed.
The 'chainstate' for this release is not always compatible with previous releases, so if you run 0.9 and then decide to switch back to a 0.8.x release you might get a blockchain validation error when starting the old release (due to 'pruned outputs' being omitted from the index of unspent transaction outputs). Running the old release with the -reindex option will rebuild the chainstate data structures and correct the problem. Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan the blockchain for missing spent coins, which will take a long time (tens of minutes on a typical machine).
Rebranding to Bitcoin Core
To reduce confusion between Bitcoin-the-network and Bitcoin-the-software we have renamed the reference client to Bitcoin Core.
Autotools build system
For 0.9.0 we switched to an autotools-based build system instead of individual (q)makefiles. Using the standard "./autogen.sh; ./configure; make" to build Bitcoin-Qt and bitcoind makes it easier for experienced open source developers to contribute to the project. Be sure to check doc/build-*.md for your platform before building from source.
Another change in the 0.9 release is moving away from the bitcoind executable functioning both as a server and as a RPC client. The RPC client functionality ("tell the running bitcoin daemon to do THIS") was split into a separate executable, 'bitcoin-cli'. The RPC client code will eventually be removed from bitcoind, but will be kept for backwards compatibility for a release or two.
The behavior of the walletpassphrase RPC when the wallet is already unlocked has changed between 0.8 and 0.9. The 0.8 behavior of walletpassphrase is to fail when the wallet is already unlocked:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 Error: Wallet is already unlocked (old unlock time stays)
The new behavior of walletpassphrase is to set a new unlock time overriding the old one:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 walletunlocktime = now + 10 (overriding the old unlock time)
Transaction malleability-related fixes
This release contains a few fixes for transaction ID (TXID) malleability issues:
-nospendzeroconfchange command-line option, to avoid spending zero-confirmation change
IsStandard() transaction rules tightened to prevent relaying and mining of mutated transactions
Additional information in listtransactions/gettransaction output to report wallet transactions that conflict with each other because they spend the same outputs.
Bug fixes to the getbalance/listaccounts RPC commands, which would report incorrect balances for double-spent (or mutated) transactions.
New option: -zapwallettxes to rebuild the wallet's transaction information
This release drops the default fee required to relay transactions across the network and for miners to consider the transaction in their blocks to 0.01mBTC per kilobyte. Note that getting a transaction relayed across the network does NOT guarantee that the transaction will be accepted by a miner; by default, miners fill their blocks with 50 kilobytes of high-priority transactions, and then with 700 kilobytes of the highest-fee-per-kilobyte transactions. The minimum relay/mining fee-per-kilobyte may be changed with the minrelaytxfee option. Note that previous releases incorrectly used the mintxfee setting to determine which low-priority transactions should be considered for inclusion in blocks. The wallet code still uses a default fee for low-priority transactions of 0.1mBTC per kilobyte. During periods of heavy transaction volume, even this fee may not be enough to get transactions confirmed quickly; the mintxfee option may be used to override the default.

bitcoin-qt command line arguments. GitHub Gist: instantly share code, notes, and snippets. If it's QT: go to "Help" -> "Debug Window" -> "console" type rpc command here. Or go from the commandline to the folder your bitcoin daemon is in and run a command from the bitcoin exe. NOTE: you may need to add server=1 to your bitcoin.conf in %APPDATA% Browse to the location of the Bitcoin Core executable (C:\Program Files\Bitcoin\bitcoin-qt.exe) and click the OK button. Next, add the command line option datadir, using the path to your data directory. Double clicking the newly-created shortcut will direct Bitcoin Core to use the new data directory. C:\Program Files\Bitcoin\uninstall.exe is the full command line if you want to remove Bitcoin Core (32-bit). The program's main executable file occupies 28.59 MB (29982224 bytes) on disk and is called bitcoin-qt.exe. The following executables are contained in Bitcoin Core (32-bit). They occupy 40.17 MB (42121598 bytes) on disk. bitcoin-qt.exe ... While you have bitcoind or bitcoin-qt running with the -server option, you can then use bitcoin-cli to run commands. It's part of the bitcoind package. If you have your conf file in a custom directory you'll have to specify that to bitcoin-cli as well, otherwise it should just work.
