This is a continuation of the Mandela Effect story.For the introduction, clickhere. How did you first become aware of the Incident? I have a lot of fans, and I often hold events that allow me to mingle with them. They have all sorts of interesting careers, and I like to ask them questions about their lives. Maybe it’s my sincerity, or maybe it’s just part of being a celebrity, but when they open up and tell me about their lives, they frequently share things that they might not tell another person. I was in a deep conversation with one of these fans, and he says “You know, I work for (the Silicon Valley Mogul) and there is just the strangest project that he’s working on. It involves you, interestingly enough.” I mean, obviously I want to know more, so I ask him more questions and he tells me about this weird guy that the NSA is surveilling. They’re tracking his internet habits and it turns out that he repeatedly googles and reads whatever are the most recent news articles on the same five people: Donald Trump, (The Silicon Valley Mogul), Kanye West, Vladimir Putin, and me. So I’m surprised, like “Wow. That’s really weird.” And obviously I’m a little worried too, because I’ve had a lot of stalkers, and it’s a really unsettling experience. So I tell him “Hey, this is really scary, and I’m kind of worried that I may have a stalker that I don’t know about. I’m not asking you to say or do anything that would endanger your job, but if he does anything else that involves me, would you please let me know?” Anyway, a few weeks passes, and I hear back from him and he says “You know, it’s the weirdest thing. He just granted you limited power of attorney in regards to IP infringement. He thinks that the NSA is trying to infringe upon his IP!” I’m like “WHAT?” It turns out that you’re verbally allowed to grant power of attorney and he did so until the end of 2019, to be extended in the event that I file any lawsuits on his behalf. What did you do? Well, I mean, what does one do in a situation like that? I talked to my friends about it. They also thought it was the weirdest thing, and one of them was laughing that we should try to get a message to him. My fan, the guy who works for (The Silicon Valley Mogul), told me that this guy reads Daily Mail a lot. It’s sort of this trashy British tabloid that has a lot of pictures in it. It’s not too expensive to insert a paid article there: in fact a lot of Z-list celebrities and Instagram influencers do it when they’re trying to get their glow-up. So as a joke, one of my friends puts a paid ad in there about me… and the guy answers! But here’s the weird thing, he doesn’t hit the post button. He responds with a thoughtful comment and then deletes it. Like what? Anyway, once me and my friends find out that we can communicate with this guy through Daily Mail, it becomes a thing for us and we try to find out his opinion about all sorts of different things. When you move through our world it can be hard to get a genuine opinion, and this guy is painfully honest. I mean, why wouldn’t he be? He deletes the posts, so there’s no evidence that they even exist. We’re the only ones who know. Anyway, it eventually becomes this sort of… game. We occasionally post paid articles in Daily Mail and ask him his opinion on things. Sometimes it’s serious stuff, like politics or racial issues. Sometimes it’s totally trivial, like… just the other day, a popular actress was asking his opinion about her ankles. Weird stuff like that. We ask his opinions through Daily Mail and my friend who works for (The Silicon Valley Mogul) relays his typed but deleted message back to us a day later. Eventually, we hear his comment about the colors. “Monochrome with a little red if you pledge your loyalty to me, blue and pink if you think I’m sexy.” And we do that too, because, hey, it’s fun. A lot of us are into fashion anyway, so this is like, a… a cool little thing to let other people know that you’re in on the secret, that you’re in the know. 21 is a special number for him for some reason - so every month, on the 21st, we dress up in hiscolors. Someof us even work themintomusicvideos, trailers for coming movies, or the colorscheme of our musictours. Even corporations are doing it too now, using these color schemes in their commercials. There are symbols, too. Like the “OK”symbol, or the illuminatisign of the trianglenearyoureye. Those apparently have some sort of significance to him also, so we try to sneak it into our paparazzi shots or poses. And then one day, I look around, and I’m like… wait a second, this is a cult. I’m in a secret cult. We have weird symbols, and similarclothing, and strange rituals we do on a certain day of the month, and a huge secret shared only by us that the rest of the world doesn’t know about. (Laugh) What is your interpretation of the Incident? Well, it’s pretty obvious. Shortly after I realized we were in a secret cult, he posted a link to a book on Amazon. It’s written like a cross between a Spellbook, an unhinged Twitter rant, and some sort of science handbook. Except this isn’t any sort of normal science. This is something called “Game Theory” and “Memetics.” Basically, those are sciences of crowd manipulation, except right now they’re still speculative – people can’t agree whether or not they exist or are just wild fringe ideas. But this guy’s theories are like, two decades ahead of everybody else. Apparently, for the past twenty years he has secretly been doing mad science experiments on how to manipulate groups, and he just proved it by starting a cult in Hollywood without even ever meeting a single one of us in person. But here’s the crazy thing – there’s no proof of any of this. Like I said, he never hit the post button on any of his comments, so there’s no proof any of them existed. If it wasn’t for the fact that we’re all doing the same things, you wouldn’t know. He’s covered his tracks perfectly. If not for the fact that you came here to interview me about it, I’d never say anything, because who would believe me? What part of the Incident would you categorize as paranormal or outside the bounds of understanding? OK, this is really going to come off as narcissistic, and I really don’t mean it to come off this way… (laughs) Go on. Well, the impression I initially had of this guy is that he was a stalker who was obsessively into me. Even after I changed my mind about that, it seemed pretty clear that he was attracted to me. I mean… to be entirely honest, I got curious and asked him about it on Daily Mail once, and he flat-out admitted it. But, the weird thing is… Yes? After January 1st, 2020, he didn’t read even a single Daily Mail article about me. Not even one.
Looks like there was a good reason for ASIC resistant coins to get pumped after all
I have been holding VTC for a while, and although I was happy with the price rising, I felt like the ASIC resistance aspect was being shilled too much. Now in light of what's happening to Bitcoin, suffering that much because of a scam coin like BCH which doesn't have half it's fundamentals because of shady tricks from Roger Ver and his friends, I think that VTC and other such coins are indeed poised to play a more and more important role in the crypto space. There will never be a real safe haven in crypto as long as the main coin is being controlled by a handful of people.
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)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
Seems BTC is starting it's bull run before 2x fork, so as expected alts will crash. What're you guys thinking of getting into after the crash? I'm thinking IOTA, VTC, BNB, and maybe another 2 or so, but would like to hear other's opinions and choices :)
https://www.reddit.com/vertcoin/comments/7ixkbf/vertbase_a_vertcoin_to_usd_exchange/?st=jb34k9jh&sh=86263ee2 They have an investor named Justin who is putting together a USD to Vertcoin only exchange. He is a pretty shrewd guy for having invested in VTC and putting this exchange together. The risk with alts being priced in BTC is a BTC meltdown. It still isn't a panacea; litecoin's sat value until very recently has been trending down while bitcoin ripped higher. GRS really seems to be doing payments well. Another virtuous goal would be untethering (lol) as much as possible from bitcoin.
What coin is your "sleeper" coin that has a promising future?
a few positive post from recent quotes of ted livingston
Libra has been a huge gift for Kin. It has validated everything we have been saying at the highest level: the big opportunity here is Money 2.0. When Libra was announced a number of people reached out to us who used to be skeptical. They are finally convinced that crypto is going to be the next big thing. Most chat apps are now launching their own cryptocurrency: Kakao, Line, Telegram, and Facebook/Whatsapp. This makes sense because, as we were the first to identify years ago, it seems to be the best way to make money in private communications. That said, none of these other messengers have gone live yet. Meanwhile Kin has been live in market for almost 2 years now, and is starting to scale. What has been exciting is that other developers are starting to realize that they may be too late, perhaps only a few months ahead of Facebook, and so it may be better to team up with another cryptocurrency rather than go it alone. From our point of view there is a big win-win if developers team up, which is the whole idea behind Kin, so it is something we are exploring in Asia as well. The price of Kin for some of these developers is important, but the real opportunity is what % of Kin you are able to own, because there will only ever be so much. This is like being an early miner of Bitcoin - if you believe in the vision then it doesn't matter what the price is today, only what % of it you are able to mine and own. but of course we will want users to have to buy from exchanges as well - remember, we all own the same Kin. Kin today is still early, but it is working. In terms of our original three step strategy, we have achieved all three steps: we have a scalable blockchain, people are using Kin inside Kik, and people are using it inside 50 other apps as well. The goals for the Ecosystem now are to:
Grow the number of apps in the Ecosystem
Grow the number of spenders in Ecosystem
Grow the number of buyers in the Ecosystem
This should allow Kin to create more Real Demand than any other cryptocurrency has today. This should have a positive impact on the price of Kin, which is obviously what Kik and every other person and developer in the Kin Ecosystem wants. Kin truly is an Ecosystem bigger than just Kik, and the snowball is really starting to roll. we are getting closer to making it easy for consumers to easily buy Kin. So for example if each of those spenders bought $1 of Kin per month, that would be $375,000 of real demand for Kin per month. If we could achieve that it would be one of the first times in the world that there was real demand for a cryptocurrency - people actually buying it to use it. And of course, the Ecosystem could grow both those numbers from there: more spenders buying more Kin each month. Focusing on real demand vs speculative demand has taken a lot more work and a lot more time, and for now Kin is being punished by the market for that - everyone else is working to drive lots of speculative demand, which Kin hasn't, and yet Kin doesn't yet have real demand either. But if Kin is able to create real demand it will be one of the first cryptocurrencies in the world to achieve that, which economically speaking should raise the price. This is what the Ecosystem is focused on, even though it means we have to go through a painful period in the meantime.
Monumental AIOMiner Update v8.4 - Mine the most profitable currencies on 74+ Algorithms (1000+ coins) while paying 0% Fees, now with free Online Rig Monitoring for your entire farm!
We’re excited to be able to call AIOMiner, the best miner on the planet!
First of all, thank you so much for all of your support over this past year! Your constant suggestions in Discord have helped make AIOMiner what it is today and we are endlessly grateful! If you haven’t yet, here are some quick links to get involved with AIOMiner:
If you’re not familiar with AIOMiner, we were born right here on /gpumining. Almost exactly one year ago, xixspiderxix became frustrated with the lack of functionality, ugliness, and the high difficulty required to get started with the already existing miners. Originally, he was just going to make it for himself to enhance his own mining experience, but others started asking for access to the software, suggesting new features, and helping him improve. So, he opened it up to the public for free and AIOMiner was born. And to this day, we maintain our promise that mining with AIOMiner will always be free. You can read more about it here, but let’s get to the good stuff!
What’s New in AIOMiner?
We now have remote rig monitoring and control through our website! We’ve just enabled the AIOMiner application to connect to the AIOMiner website through an API and fixed some bugs. If you’ve never used AIOMiner before, here are some of the features you can expect on the software side of things:

takes deep breath
Q: How many cryptocurrencies does that cover? A: ¯\(ツ)/¯ We stopped counting when we reached 1,000.
Every week we put on an event called Free Hash Friday, and don’t call the DEA because we're not giving away weed! Maybe Canada can help you with that, but here's the general rundown for Free Hash Friday: The AIOMiner team sends out a tweet every week with directions in an image, such as this one. Follow the directions in the tweet where it says "To Win" with the arrows. Once you've completed those three steps, your twitter handle will be inputted into a spreadsheet (that is shared with the public) and you'll be assigned a number in the order that you're inputted. You have until 8pm US Pacific Time (GMT -7) to enter. At 8pm, the spreadsheet will be updated one final time and the drawing will begin immediately in the AIOMiner discord channel. You'll notice on the spreadsheet that you have a number next to your twitter handle. We have a bender bot that is able to generate a random number given the upper and lower limit. If your number is the randomly generated number, you win! Typically we pair with a coin, as you can see, who puts up some to giveaway and we have multiple winners. If we don't have a coin to give away, The AIOMiner team will simply start mining on behalf of the winner for 24 hours and mine any gpu-mineable coin of their choice. And that's pretty much it! So, follow our twitter and be on the lookout for the next Free Hash Friday!
What else should I know about AIOMiner?
We are fully committed to keeping mining free for everyone, but it does cost some money to keep the servers up and running. So, we're planning on releasing some "premium" features in the near future that will take the mining experience to the next level. Until December 1st, we will allow users to donate/purchase a lifetime premium account. With this account you will gain access to AIOMiner and all of the premium features that we release as well as any future product we make for free. This is only for a limited time, so if you're in the mining game for the long haul, it is definitely worth it. After December 1st, we will open up the premium features on a membership/monthly subscription basis. So, get it while it's hot!
Other than that, enjoy the software, enjoy the giveaways and come participate in the community:
Thank you again to everyone who has helped make AIOMiner what it is today!
Happy Mining, -The AIOMiner Team Edit: When releasing the new website, Google's Crawler flagged us as experiencing a hostile takeover and as a result, you may get a message warning of malicious content. We checked everything and there is no malware or malicious software on aiominer.com. We are actively working with Google to get this resolved as quickly as we can!
Most of use know that groestlcoin and vertcoin are compared because they have similar visions. They are both asic resistant coins that are segwit and lightning network compatible but what sets them apart? Groestlcoin coin has a smaller market cap as its just began its marketing 2 weeks ago. It's full of tech and looking to get its share of the market. What does GRS have? - Mining is optimised for both Amd and Nvidia with its easy miner mining application - Samourai stealth address wallet for private transactions - Wallets to fit your needs including ios, android, blackberry, Mac, PC and Web wallets. Find our more here http://www.groestlcoin.org/downloads/ - Tor Wallet - Multi signature wallet - Multiplatform synced wallet - 80 electrum severs What's in the pipeline? - Hardware support for ledger and Trezor - Further website redesign including roadmap - project underway to connect GRS to the gaming world - Atomic swaps and lightning network - rebranding vote early next year - Anonymous transactions are being developed for the future that will compete with the likes of monero What does VTC have? - Nvidia mining with the one click miner - Hardware support - Android, Mac and Windows wallets - Tor Wallet - Large community - 4 electrum servers What's in the pipeline? - stealth address wallets to be developed - Amd optimisation for the One click miner - Halving coming up - Atomic swaps and lightning network - Multi platform wallet In summary both these coins are great and have bright futures. In my opinion GRS edges it on tech and VTC edges it on branding and community. Both are good beta s for the future as asic resistance comes more relevant with the Bitcoin forks disrupting the market. Any errors or additions comment below and I will add
Debunked: "Mining became centralized because Satoshi didn't anticipate pools and pooled mining"
Whether he specifically expected pools for ordinary users or not is largely irrelevant, as he did expect a collection of miners connecting via a single node. But everything seems to suggest that he did, as he even helped building and encouraging the transition.
Only people trying to create new coins would need to run network nodes. At first, most users would run network nodes, but as the network grows beyond a certain point, it would be left more and more to specialists with server farms of specialized hardware. A server farm would only need to have one node on the network and the rest of the LAN connects with that one node.
The more burden it is to run a node, the fewer nodes there will be. Those few nodes will be big server farms. The rest will be client nodes that only do transactions and don't generate.
Source If anything, pools give lower hash competitors a steadier revenue and thus increases the number of market participants past what one might otherwise have expected without them, once an equilibrium hashing node count had been reached. So what did Satoshi think about pools then? Here are 1,2 links to Satoshi working on and discussing the benefits of pooled mining. The first link happens to be a few days before the first official Bitcoin mining pool started, at which point the basic concept had already been tested for months. Still worried that ASICs might have been the problem? Then this is for you.
We Are Proud To Announce Our First Community Spotlight - The All-In-One Miner (AIO Miner)
After discussion among the Moderators, we felt that it would be a great idea to have a Community Spotlight on this subreddit for the great content created by our subscribers (there’s a lot of great content that is only on the front page for a day or so since we’re so active and then lost to the history books). When members of the subreddit create content that is valuable to the subreddit and mining community as a whole, we’ll be happy to put it in the spotlight for a bit to share with the community. The Community Spotlight is open to everyone. Simply Message the Moderators with your entry and a suggested post! The post should be well written, easy to understand, and pre-formatted to qualify. It will be stickied to the top of the subreddit and added to the subreddit sidebar, possibly the wiki if it is highly informative.
Our first Community Spotlight is The All-In-One Miner created by xixspiderxix (AIO Miner for short). The goal of the AIO Miner (in Alpha) is to make mining as easy as possible and accessible to everyone no matter your technical abilities. A key part of this was to get rid of .bat (batch) files and instead simply select the coin you want to mine and point the miner at the pool you want to mine from.
Pool Management Easy Pool Setup Auto start mining on start of application. Following a schedule of coins you want to mine throughout the week. E-Mail Alerts. Automatically starts mining on idle. Prices right on the front of the application of all supported coins updated every 5 minutes. Displays current hashrate on the front of the application. Displays current GPU Power Usage Enables Auto-Login for your windows machine. Enables AIOMiner to start as soon as you boot. Disables Automatic Windows Updates. Backup/Import settings. Change your coin prices to multiple currencies. Review individual card performance. Monitors mining progress, and if errors occur attempts to recover the miner. Automatic reboots if multiple failures occur..
Ethereum BitcoinZ STRAKS zCash Vertcoin Mona Komodo Hush ZenCash (With more coming very soon!)
Windows Nvidia GPUs
How can the community help?
Alpha/Beta testers are badly needed! So, if you have a mining rig running Windows with Nvidia graphics cards, you’re eligible to be a tester! Simply download the AIO Miner and give feedback either here or on the discord channel. AMD Support - Pending for someone to donate an AMD card or a dev to buy one. But you are on the list!
So Please! Ask xixspiderxix anything you'd like about AIOMiner!
Hey guys, I thought I would put together an in-depth tour of the Gridcoin wallet software for all of our recent newcomers. Here I'll be outlining all the features and functions the windows GUI wallet has to offer, along with some basic RPC command usage. I'll be using the windows wallet as an example, but both linux and macOS should be rather similar. I'll be including as many pictures as I can as embedded hyperlinks. Edit: Note that since I originally made this there has been a UI update, so your client will be different colors but all the button locations are in the same place. This is my first post like this, so please forgive me if this appears a little scatter-brained. This will not cover the mining setup process for pool or solo miners. When you launch the wallet software for the first time you should be greeted with this screen.
If you're a pool miner or investor, press cancel.
If you're a solo miner, enter your email you used to sign up for projects and press OK.
If you're not sure or haven't decided yet, press cancel. We can come back to this later.
After that prompt, you should be left sitting on the main overview tab with several fields on it. From top to bottom:
Available: All coins available to be sent or staked (I'll cover this term later).
Stake: All coins that are currently staking.
Unconfirmed: All coins that have been received and have not yet received 110 confirmations.
Total: All coins in your wallet. (The sum of the above fields)
Blocks: How many blocks your client has in it's chain. Your wallet just started syncing with the network so this number will be low.
Difficulty: How difficult it is for someone to stake the next block.
Net Weight: An estimate for how many coins are staking on the entire network.
Coin Weight: How many of your coins that are currently staking.
Magnitude: A quantifier for how much work you put in mining. For solo miners only. For pool miners, this value will always be 0.
Project: Displays the projects you're working on, one at a time. For solo miners only. For pool miners, this will always say "INVESTOR".
CPID: Cross Project Identifier. Used to keep track of users across projects. For solo miners only. For pool miners, this will always say "INVESTOR".
Status: Displays various status messages.
Current Poll: Displays the latest poll.
Client Messages: Displays various client messages.
Now onto the other tabs on the left side. Currently we're on the Overview tab, lets move down to the Send tab. This tab it pretty self-explanatory, you use it if you want to send coins, but I'll go over the fields here:
Pay To: Enter a valid gridcoin address to send coins too. Gridcoin addresses always start with an S or and R.
Label: Enter a label here and it will put that address in your "address book" under that label for later use. You can leave it blank if you don't want it in your address book.
Message: Enter a message here if you want it attached to your transaction.
Amount: How many coins you want to send.
Add Attachment: Leave this alone, it is broken.
Track Coins: This doesn't do anything.
Now down to the Receive tab. Here you should have a single address listed. If you double click on the label field, you can edit it's label.
New: Generate a new address.
If you click on an address, the rest of the options should be clickable.
Copy: Copy the selected address to your clipboard.
Show QR Code: Show a scan-able QR code for the selected address.
Sign Message: Cryptographically sign a message using the selected address.
The Transactions tab is pretty boring considering we have no transactions yet. But as you can see there are some sorting tools at the top for when you do have transactions listed.
ADDRESS BOOK TAB
The Address Book is where all the addresses you've labeled (that aren't yours) will show up.
Verify Message: Verifies a message was signed by the selected address.
The rest of the functions are similar to the functions on the Receive tab.
Onto the Voting tab. There wont be any polls because we aren't in sync yet.
Reload Polls: Pretty self-explanatory, I've never had to use this.
Load History: By default, the wallet will only display active polls. If you want to view past polls you can use this.
Create Poll: You can create a network-wide poll. You must have 100,000 coins as a requirement to make a poll. (Creating a poll does not consume the coins)
Display coin control features (experts only!): This allows you to have a great deal of control over the coins in your wallet, check this for now and I'll explain how to use it further down. Don't forget to click "Apply".
ENCRYPTING YOUR WALLET
Now that all of that is out of the way. The first thing you'll want to do is encrypt your wallet. This prevents anybody with access to your computer from sending coins. This is something I would recommend everyone do. Go to Settings > Encrypt Wallet and create a password. YOU CANNOT RECOVER YOUR COINS IF YOU FORGET YOUR PASSWORD. Your wallet will close and you will have to start it up again. This time when it opens up, you should have a new button in the bottom left. Now if you want to stake you will have to unlock your wallet. Notice the "For staking only" box that is checked by default. If you want to send a beacon for solo mining or vote, you will need to uncheck this box.
GETTING IN SYNC AND ICONS
Before we continue, Let's wait until we're in sync. Depending on your internet speeds, this could take from several hours to over a day or 2. This can be sped up by using Advanced > Download Blocks, but this can still take several hours. This is what an in-sync client should look like. Notice the green check to the right of the Receive tab. All of these icons give you information when you hover your mouse over them. The lock The arrow tells you if you're staking. If you aren't staking, it will tell you why you're not staking. If you are staking it will give you an estimated staking time. Staking is a very random process and this is only an estimate, not a countdown. The connection bars tell you how many connections to the network you have. The check tells you if you're in sync.
WHAT IS STAKING?
Now I've said "stake" about a million times so far and haven't explained it. Gridcoin is a Proof of Stake (PoS) coin. Unlike bitcoins Proof of Work (PoW), PoS uses little system resources, so you can use those resources for scientific work. PoS works by users "Staking" with their balance. The higher the balance, the higher the chance to create, or "stake" a block. This means you need to have a positive balance in order to stake. Theoretically, you can stake with any amount over 0.0125 coins, but in practice it's recommended to have at least 2000 coins to reliably stake. Staking is important for solo miners, because they get paid when they stake. Pool miners don't need to stake in order to get paid however. So if you want to solo mine, you'll need to buy some coins from an exchange or start in the pool first and move to solo when you have enough coins. In addition to Research Rewards for miners, anyone who holds coins (solo miners, pool miners, and investors) gets 1.5% interest annually on top of your coins. So it can be beneficial for pool miners to stake as well. Here is a snippet of what a research rewards transaction looks like from my personal wallet. I have a label on that address of "Payout address" as you can see here.
UTXOS AND COIN CONTROL
At this point you'll need some coins. You can use one of our faucets like this one or this one to test coin control out. First let me explain what a UTXO is. UTXO stands for Unspent Transaction Output. Say you have an address with 0 coins in it, and someone sends you 10 coins like I've done here. Those 10 coins are added to that address in the form of a UTXO, so we have an address with one 10 coin UTXO in it. Now we receive another 5 coins at the same address, like so. Now we have an address with one 10 coin UTXO and one 5 coin UTXO. But how do we view how our addresses are split up into different UTXOs? Earlier we checked the "Display coin control features" box in Settings > Options > Display. Once that's checked you'll notice there's another section in the Send tab labeled "Coin Control Features". If you click the "Inputs" button, you'll get a new window. And look, there's our 2 UTXOs. All UTXOs try to stake separately from each other, and remember that the chance a UTXO has to stake is proportional to it's size. So in this situation, my 10 coin UTXO has twice the chance to stake as my 5 coin UTXO. Now wallets, especially ones that make a lot of transactions, can get very fragmented over time. I've fragmented my wallet a little so I can show you what I'm talking about. How do we clean this up? We can consolidate all this into one UTXO by checking all the boxes on the left and selecting OK. Now pay attention to the fields on the top:
Quantity: The total amount of UTXOs we have selected.
Amount: The total amount of coins we have selected.
Fee: How much it would cost in fees to send all those UTXOs (more UTXOs = more transaction data = more fees)
After Fee: Amount - Fees.
Bytes: How large the transaction is in bytes.
Priority: How your client would prioritize making a transaction with this specific set of UTXOs selected had you not used coin control.
Low Output: If your transaction is less than 0.01 coins (I think).
custom change address: You can set the address you get your change back at, by default it will generate a new address.
So let's fill out our transaction so we end up with 1 UTXO at the end. In "Pay To:" Just put any address in your wallet, and for the amount put what it has listed in the "After Fee" Field. Just like this. Notice how we get no change back. Now click "Send", we'll be prompted to enter our passphrase and we're asked if we want to pay the fee, go ahead and click "Yes". Now if we go back to the Overview tab we get this funky icon. If you hover your mouse over it, it says "Payment to yourself", and the -0.0002 GRC is the network transaction fee. (Ignore the first one, that was me fragmenting my wallet) Now if we look at the Coin Control menu, we can see that we've slimmed our wallet down from 7 UTXOs to 1. Now why would you want to use coin control? 2 Situations:
UTXOs less than 0.0125 coins cannot stake. So you can combine a lot of tiny, useless UTXOs into 1 bigger one that can stake.
After a UTXO stakes, it cannot stake for another 16 hours. So if you have 1 large UTXO that is big enough to stake more than once every 16 hours, you can split it into smaller UTXOs which can allow you to stake slightly more often.
By default, the wallet will always generate a new address for change, which can make your wallet get very messy if you're sending lots of transactions. Keep in mind that more UTXOs = larger transactions = more fees.
Sidenote - When you stake, you will earn all research rewards owed reguardless of which UTXO staked. However, you'll earn the 1.5% interest for that UTXO. Not your whole wallet.
A fork is when the network splits into multiple chains, with part of the network on each chain. A fork can happen when 2 blocks are staked by different clients at the same time or very close to the same time, or when your client rejects a block that should have been accepted due to a bug in the code or through some other unique circumstance. How do I know if I'm on a fork? Generally you can spot a fork by looking at the difficulty on your Overview tab. With current network conditions, if your difficulty is below 0.1, then you're probably on a fork. You can confirm this by comparing your blockhash with someone elses, like a block explorer. Go to [Help > Debug Window > Console]. This is the RPC console, we can use to do a lot of things. You can type help to get a list of commands, and you can type help [command you need help with] (without the brackets) to get information on a command. We'll be using the getblockhash [block number] command. Type getblockhash [block number] in the console, but replace [block number] with the number listed next to the "Blocks:" field on the Overview tab. This will spit out a crazy string of characters, this is the "blockhash" of that block. Now head over to your favorite block explorer, I'll be using gridcoinstats. Find the block that you have the hash for, use the search bar or just find it in the list of blocks. Now compare your hash with the one gridcoinstats gives you. Does it match? If it matches, then you're probably good to go. If it matches but you still think you're on a fork, then you can try other block explorers, such as gridcoin.network or neuralminer.io. If it doesn't match, then you need to try to get off that fork. How do I get off a fork?
Just wait for an hour or two. 95% of the time your client is able to recover itself from a fork given a little time.
Restart the client, wait a few minutes to see if it fixes itself. If it doesn't restart again and wait. Repeat about 4 or 5 times.
Find where the fork started. Using the getblockhash command, go back some blocks and compare hashes with that on a block explorer so you can narrow down what the last block you and the block explorer had in common. Then use reorganize [the last block hash you had in common]. Note that reorganize takes a blockhash, not a block number.
A listening node is a node that listens for blocks and transactions broadcasted from nodes and forwards them on to other nodes. For example, during the syncing process when you're getting your node running for the first time, you're downloading all the blocks from listening nodes. So running a listening node helps support the network. Running a gridcoin listening node is simple. All you need to do is add listen=1 to your gridcoinresearch.conf and you need to forward port 32749 on your router.
