Error starting up new Bitcoin Unlimited BCH node.
EDIT: Fixed, I just needed to run "./bch-unlimited-188.8.131.52/bin/bitcoind --daemon -reindex" It's fully synced now. It was syncing for awhile at first but now it keeps crashing whenever I run the following command."./bch-unlimited-184.108.40.206/bin/bitcoind --daemon" It throws the error "Error: Failed to connect best block"Below is the log. Any help is appreciated.

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. Ubuntu http://groestlcoin.org/forum/index.php?topic=441.0
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)

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.
It is hoped that Earthcoin will bring new opportunities to the global village economy under the influence of the new crown virus, and the Earthcoin EAC blockchain will build a new global village.
It is hoped that Earthcoin Earthcoin will bring new opportunities to the global village economy under the influence of the new crown virus, and the Earthcoin EAC blockchain will build a new global village. Everyone becomes a member of the global village via the Internet, but the real world is divided into many countries and regions. National and regional laws, currencies are inconsistent. The advent of blockchain can build a global village. 1: Global Village, EarthCoin A word that the Global Village heard a long time ago seems to be a bit old now. The rapid development of modern science and technology has reduced the space-time distance on the earth, and international communication has become increasingly frequent and convenient, so the entire earth is like a small village in a vast universe. The global village in the Internet era is imperfect, because only the rapid transmission of information, and other aspects are deeply affected by the real world. Earth's development of the digital economy is inseparable from Earth Coin EAC! EAC can help users to pay instantly to anyone on the planet. Earthcoin is a global decentralized payment network and digital currency that calculates the value of labor and quantifies the resources of the earth. Inspired by Bitcoin. Earthcoin can perform fast transactions with little or no fees. No login, registration or hidden fees are required. Users receive Earthcoin or send Earthcoin from any Earthcoin address in the world within seconds. Earthcoin uses P2P technology, and there is no central management agency; the network collectively manages transactions and issues Earthcoin. Earthcoin is also open source. Its design is public participation. No one can own or control Earthcoin. It is committed to sustainable and fair development. It calculates labor value and quantifies earth resources. Every earth person can participate. 2: The current global village In reality, everyone's connection is broken. You have to use your own currency, you have to abide by your country's laws and regulations, and you have to follow a local law to use the local currency when you go to an area. Many things are inefficient because of this split. For example, bank cards: everyone has a lot of bank cards. There is nothing necessary. How many cards are wasteful. If you want to transfer money, the bank is different. If you want to transfer money from two different countries, you have to go through A complex network is very inefficient. Earthcoin is a global decentralized payment network and digital currency that calculates the value of labor and quantifies the resources of the earth. Can completely solve these problems. 3: If the blockchain changes the global village The above problem is the reason why there is no strong center. If there is only one country and a bank is so big, things can be very efficient. But it is impossible. The United Nations and the World Bank can be political centers and financial centers by name, but the actual situation is not. The actual power is poor. And it may not be a good thing to create such a strong center, Earth Empire? The emergence of the blockchain has created a new possibility without a center! A lot of things need to be done by the strong center, but they are done just as well by going to the center. 1. In the past you needed the government to prove who you are, your mother is your mother, now the blockchain can. 2. In the past, you needed to use different currencies in different countries, and now Bitcoin Geocoin is accepted in any country, regardless of exchange rates. The short confirmation time of the Earthcoin EAC block gives it infinite potential to extend to payment applications. Everyone knows that Bitcoin BTC is the most robust and secure currency in the block. Even a few years ago, many investors around the world have used it as a tool for their own wealth transfer and storage. In the field of value storage, its credit is unmatched, which is the fundamental reason for its market value of 1.4 trillion. However, in the global micropayment application, Bitcoin BTC requires 10 minutes for each block confirmation, and 6 blocks can ensure accurate transactions. If you are shopping in the supermarket or participating in remittances, fundraising, etc., you only pay a sum of money. Wait for 10-60 minutes, it will definitely make people restless, don't even think about doing anything. Earth Coin EAC has a block time of 60 seconds, and 5 blocks can confirm the transaction. Although there is no Alipay and WeChat Express supported by a centralized database, you have realized a point-to-point seamless link payment globally. , Waiting for confirmation within a few minutes is completely acceptable! At present, the United States and Europe have begun to encircle China's Alipay and WeChat in terms of financial payment, because it is quickly eating away the cake of the cross-border payment of US dollars and euros in the circulation between Southeast Asia and Europe. Zuckerberg, knowing that his Lbria is equivalent to QQ currency ten years ago, but the US government has almost allowed it [to resist the pressure brought by Chinese payments, but if it is to be issued, it will become the Federal Reserve. And the US dollar's grave diggers were ultimately rejected by Congress], they are all centralized in nature, just like Huawei, no matter how good the product quality is, and where the service is in place, but as long as Huawei is found as a centralized organization, it is because of geopolitics between countries. And under economic coercion, bans are banned. But with a payment system developed using pure POW digital currency with a short confirmation time, no government can start, and people in Asia, Europe, Africa and the United States will long to use them to complete transnational payments in the context of globalization. Four: Summary This article triggered my thinking on the blockchain. What is the purpose of decentralization and why do many things go to the center! !! !! In a small area, a strong center is enough to accomplish many things efficiently, but when there is no strong center and it is difficult to exist globally, many simple things are very complicated. 1. Online transfer, if there is Alipay, then it will be a few seconds, but if a Chinese person uses Alipay to transfer to an overseas PayPal account, it is a massive project. After a bunch of banks, exchange rates fluctuated and various fees were charged. Blockchain can transfer money in a few minutes like Alipay. The short confirmation time of the Earthcoin EAC block makes it have endless potential to extend to payment applications. 2. Self-certification, you have to prove who you are, you need proof of where you are registered, you ca n’t prove who you are, you ca n’t prove it, but the district Blockchaining your private key can prove who you are. 3. More secure, Alipay transfer is a strong center, which is theoretically very safe, but it is a black box for you. If something goes wrong, if something goes wrong, how do you prove that you transferred, everything depends on the credit of Alipay, but the blockchain depends on It is code, and everyone can view the public code, which is more credible. Blockchain has many limitations. Without a strong center, there is no strong center, but in many cases, there is no strong center, and then a blockchain is necessary. I hope Earthcoin brings new opportunities to the global village economy under the influence of the new crown virus! (Source network)
My bch pruned testnet servers suddenly stopped getting blocks
I have a few bch nodes running on bitcoin-abc v0.16 and v0.17, on my local machine and other servers. They all suddenly stopped getting new blocks at block 1231688. We are around block 1231718 now. I have tried adding nodes I can find and restarting bitcoind and can't get them to download the newer blocks. My testnet nodes are useless at this point. Does anyone know a way to fix this? Here are some of the debug.log entries. After the portion below, it says "connect() to failed after select()..." for eternity.

Update: they are caught up now. I am not sure what the exact cause of the delay was besides maybe having to find new nodes to connect to. They were behind for about 24 hours and now it's back to normal.
Solution: Blockchain Voting-- a secure electronic voting framework that we needed yesterday. Voting fraud happens because of 2 things: a) CorruptGov runs elections, b) Inconsistency in voting systems act as 'plausible deniability'.
TL;DR: These guys claim we're ready for it now, for the 2016 election:
Background Our government has cheated elections several times and they will continue to cheat and steal the vote so long as we can blame tallies on little old ladies counting the ballots; disenfranchised black people in florida; hacking; "lost" absentee ballots (or suddenly 'found' absentee ballots); diebold voting machines (or whatever they call themselves now); misreporting from the media; supreme court decisions that were wrong (gore v bush) because it was a politically-imbalanced cabinet at the time; and finally the existance of a theivery corporation's ploy called the electoral college as a means to overrule any deep-state-disapproved, democratically-elected republicanism. These inconsistencies in our voting systems allow a corrupt government to 'get away with it', because 'problems' act as a 'plausible deniability' gambit for fraud. While the Spectacle spins off countless hours of news media coverage over the "possibility of fraud" and election scandals, talking bobble heads gobble on with ineffectual nonsense to a captive audience with the sole intention of selling pharma medications that don't work, food that's not fit to eat, and cars we can't afford. In other words, controversy is commodified: we'll be taking your money, kthanxbye.
Steal elections. 'lections. Make money, money. Steal elections 'lections. Make the money money. Somewhere in there is a hit rap song.
Enter Blockchain Voting It's important to enumerate all those problems, not as a whiny rant, but to demonstrate how Bitcoin technology can absolutely free us from these problems and end all controversies, so that we can get back to the task we once had of making this world a freer, better place for all humans everywhere (which is--to my mind--the core assumption of american exceptionalism). Blockchain The *Blockchain is an electronic, cryptographic public ledger used in bitcoin to track all transactions that have ever happened. It's used as parity check to prevent double spending (similar to the 90s era ecommerce problem of "click only once"). Anyone using bitcoin has a copy of every transaction that has ever been made. This means that every bitcoin user is part of one giant virtual bitcoin based bank with direct access to the bank's database of transactions. Think about how powerful that is.
It also means that the idea that bitcoin is anonymous that is commonly held (and propagandized by the main stream media as 'a money technology that enables crime') is simply false--its only semi anonymous. This means that bitcoin transactions are all traceable. This is why if you want anonymity, you use an online proxy service to create temporary bitcoin addresses to anonymize yourself, but this only protects you by hiding behind the service itself. There is soon to be a darkweb version of this service which will be a tor hidden service that will not be answerable to any government, and that will ensure true anonymity.
The blockchain is a powerful tool, and people are utilizing the metadata aspect of the blockchain in several creative ways. One in particular is in creating a secure electronic voting framework These guys claim we're ready for it now, for the 2016 election:
Colors Bitcoin can create this framework in many ways; but I believe most popularly it would use an exploitation of bitcoin' 'colored coins', 'tagging' coins with a form of metadata. Such as blue or red; business or personal; savings or dailyexpenditures; Hillary or Trump. In the case of bitcoinvoting, the 'value' aspect of the coins would be irrelevant. So one would only have to solve bitcoin for a relatively small number of bitcoins. Given that the smallest unit in BTC is 0.00000001 BTC, only 2 BTC would be needed to enable this, giving each person 0.00000001 BTC; if you used 3-5 BTC, that would be enough for at least the next 100 yrs of voting, given the US population is currently around 318.9M, and less than that would be legal to vote So in this scenario, casting a vote would entail spending 0.00000001 BTC of Bernie-colored coin or Trump colored coin, to a bitcoin address representing your county's ballot box (or a federal ballot box address). You have a copy of your transaction, so do they, and you have everyone elses's vote, and so do they. Semi-Anonymity is implicit because bitcoin addresses are just numbers, although they are traceable. This can be resolved fairly easily by using a central server. People will complain and say "who runs the server"? With bitcoin, it doesn't matter... you still have a copy of your vote and can check it. It precludes changing your vote. It elminates this problem entirely. The 'Registration process' would need to be figured out. It could be the case that 2 bitcoin systems are used, one that registers a voter and another that handles casting votes. How it Fixes
) Tally -- blockchain public ledger allows anyone to count the votes -- Fixed!
) Government changes votes in the database -- blockchain ledger disallows -- Fixed!
) Voting machine problems -- it's all electronic, consistent with bitcoin voting. All you need is a computer, the open source voting system is security-audited by the public and runs off a CD as a diskless OS. You print a paper wallet and write your vote to it --- fraud = Fixed!
) Absentee ballots -- no longer exist. You can vote instantly from anywhere in the world -- Fixed!
) Misreporting from MSM -- can't happen anymore as anyone can call immediate bullshit with software designed to tally based on your blockchain -- Fixed!
) Supreme Court Decisions -- blockchain won't fix a bad decision from the SCOTUS -- NOT FIXED! Although the people will have perfect evidence to hold the court itself in contempt of court and hold a collective vote of no confidence calling for immediate, permanent disbarrment of all members of SCOTUS from any future government office. Or we shoot them dead.
) Electoral college -- blockchain won't fix this so long as we have a system that politically upholds a fraudulent misapplication of democracy like this. However it will amplify differences between the two, supporting a narrative that the electoral college is the "Establishment's" vote versus the "people's vote". So it's a NOT FIXED! However, I believe people would like the democracy enabled by blockchain voting that they'd run towards it and admonish the electoral college as perfect manifestation of deep state elitism.
Re: Item #3 above: yes, not everyone has a computer. So you would have to have voting places still, but they would be computer labs connected to the internet or libraries, or your friend's computer...any computer that can boot from CD or USB stick can become a voting machine. There is software that hash-checks the diskimage and writes a certified copy to your media; you boot to it and it turns off every device but monitor, mouse and internet...it connects to internet to check your registration; or you just send your registration and vote info and if you do it again, it will overrule the last vote or ignore it (a decision to make...should you be able to change your mind prior to the election day, by which all votes must be cast and beyond which they won't be counted...

This refers to the number of inconsistencies found in the data. These inconsistencies can be discovered by using outlier detection techniques. The lower the variability, the more high quality the data. An increase in data variety can also lead to high variability. Big Data Use Cases When I opened the Bitcoin Core program, the GUI gets to "Done loading" and then hangs about 5 min. This was happening the last few days (v0.14.0). After continuing, it will start catching up/syncing (it is now 2 days behind). After a some time (I don't know exactly) the Bitcoin Core client freezes again, and it hangs indefenitly. BHB in China raised $20 million in 2018 touting a three-person team. The only problem?
