Wallet Question: With an offline Armory wallet do I really need Bitcoin-QT? Can't I just generate an address on the offline computer and add that address to my Blockchain.info account as a watch only address? From there won't I be able to receive payments and view the balance?
Or am I missing something (like all of my bitcoins)?
Wich is the best bitcoin GUI wallet right now, Bitcoin Knots, Bitcoin Core or Electrum. I want to put bitcoin wallet on my laptop, and what about blockchain size, I still have 100gb free size on my ssd will it be enough?
Okay so I know this question is highly subjective which is why I’m asking it in the first place. There’s tons of different kinds of Bitcoin wallets out there and I’m curious as to what everyone here is generally using. So to re-phrase the question; in your personal opinion, what would you consider to be the best Bitcoin wallet and why? What do you think the best Bitcoin wallet for newbies is? There’s tons of newbies here (including myself) and being able to read through the community’s responses is highly beneficial to newcomers. Thoughts?
We are pleased to announce that after many hard months of work, Peercoin v0.9 (Codename Strider) is complete and a hard fork is planned for Monday, June 8th, 2020 at 12:00:00 UTC. You must upgrade your wallet client before then!
ability to filter out mint transactions in the QT wallet
While Peercoin v0.8 (Mantis) was largely about modernizing the codebase and improving the technical capabilities of the reference node software, the v0.9 (Strider) development cycle was about the economics of the Peercoin cryptocurrrency. Both the PoW and PoS aspects of the network have been modified. Proof-of-Work changes are rather minimal; in summary target block spacing has been set to 60 minutes, rather than having dynamic PoW block spacing target. Block spacing is currently approximately 60 minutes anyway, so this may not sound like a big change, but it stops some PoW pools from trying to game the system. By making PoW more predictable, RFC-0019 brings inflationary stability to the overall system. That change is minor when compared to the modification of the Proof-of-Stake side of the system. Some of you may have been following the discussion on RFC-0011, which was ongoing for over a year, and you may have noticed that RFC-0011 was rejected about two weeks ago and replaced with RFC-0018. In my personal opinion, RFC-0011 is a great idea, probably the best idea thrown around here in the last couple of years, but ultimately it's too complex and we could not get consensus about it. The gist of both RFC-0011 and RFC-0018 is that the Peercoin money supply inflates at a rate of 1% on paper, but we are nowhere near that in practice. In the old system, in order to have PoS inflation at 1%, a full 100% of all peercoins would have to start minting and solving blocks. This is simply impossible. In reality, over the last couple years Peercoin's PoS inflation has only been between 0.10% and 0.20%, which is far from the "promised" annual 1%. Due to the very rough history of this beautiful blockchain, namely the closure of btc-e, dozens of exchange hacks and closures, as well as a couple of de-listings, we are in a situation today where nearly half of the monetary supply has not been moved for over two years and we can consider those coins lost for all intents and purposes. The basic principle of RFC-0011 was the following: the Peercoin network promises a steady inflation of 1% on monetary supply, and if you want a cut of it: mint. In essence, if only 20% of all peercoins are minting, the effective reward for active minters would be closer to 5% per year. However, the problem with this scheme is that minters would try to game the system and only mint when minting participation is low. Thus, we came up with RFC-0018, which yields similar results, but keeps the reward calculation simple and prevents gaming of the algorithm. You can read more about the change here. Long story short, the network will reward active minters more, while keeping the overall inflation around 1%. Accompanied with an expected inflation drop from increasing PoW hashrate, overall monetary inflation will largely remain unchanged, and will be more stable. Other changes are minor and do not change the behavior of the network. RFC-0017 is just a consequence of RFC-11, and it stops minters from going offline for longer than a year and coming back to mint. We did not see this as fair, so the coinage counter is reset after a year now. Limiting coinage disincentivizes extremely long term periodic minting, thereby making continuous minting more attractive. -- Peerchemist, Peercoin Project Lead
Before installation, make sure to backup your wallet from the main menu.
The v0.9 client can be downloaded from the wallets page of peercoin.net. For users upgrading from v0.8, upgrade instructions can also be found on that page. For the minority of users that may have skipped v0.8 and are upgrading from v0.7 or earlier, please check these additional instructions from the previous v0.8 release thread as you will need to go through the additional process of rebuilding your block database. If you need help with installation, leave a comment below.
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)

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.
Hello, I have been a fan of electrum because of its offline capability. I like that I can use Bitcoin while storing my private keys on a computer that has the wifi card removed and hot glue stuffed in the Ethernet port. However it looks like maybe the electrum developers have over-promised and under-delivered in this regard. Or, maybe they simply do not have the time, energy, resources to make this work in real life. Let me explain. I have an old-ass computer that is running Ubuntu 12 (precise), this computer has electrum 2.5.4 installed with a cold-storage wallet that has my private key. I want to send some bitcoin from that address to a new wallet on my desktop so I can spend the bitcoin. So I installed electrum (newest version 3.3.8) on my desktop, imported the bitcoin address, and created a transaction. Then I sent the transaction to the offline computer out of band, and verified that the out-of-band transmission worked by comparing the hash of the txn file on both the offline and online machines. Then I tried to open the txn file on the offline machine with Electrum 2.5.4. Well, guess what, it didn't work. Electrum 2.5.4 printed to the console: Traceback (most recent call last): File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/main_window.py", line 2261, in do_process_from_file self.show_transaction(tx) File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/main_window.py", line 577, in show_transaction show_transaction(tx, self, tx_desc) File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/transaction_dialog.py", line 37, in show_transaction d = TxDialog(tx, parent, desc, prompt_if_unsaved) File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum_gui/qt/transaction_dialog.py", line 48, in __init__ self.tx.deserialize() File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum/transaction.py", line 523, in deserialize d = deserialize(self.raw) File "/uslocal/lib/python2.7/dist-packages/Electrum-2.5.4-py2.7.egg/electrum/transaction.py", line 454, in deserialize d[inputs] = list(parse_input(vds) for i in xrange(n_vin)) OverflowError: Python int too large to convert to C long That's pretty frustrating, the first thing I tried was to install Electrum 2.5.4 on my Desktop and try to create a new unsigned transaction with Electrum 2.5.4. However, this is a no-go because old versions of Electrum cannot connect to Electrum servers any more. So I have to try to update the Electrum on the Offline computer. But I'm not even sure if this is possible considering how ubuntu 12 it's definitely out of support at this point and the offline computer does not even have python3 installed, let alone the GTK stuff or whatever is probably required to run Electrum. I'm starting to regret choosing a GUI-based wallet for my offline storage considering how hard it is to actually use this and how it simply melts over time... even just 5 years is is enough time to completely melt and destroy this software and make it un-usable. Time Catches All. So now I have to go out and buy a new computer that can run the updated OS, so I can install the new version of Electrum, so I can access my bitcoin. Do you have any other ideas? Has anyone else experienced anything like this?
Very Positive Experiences of a Bitcoin Beginner and Some Tips Learned Along the Way
Well, it has sure been a whirlwind week, but I finally own my first portion of BTC and couldn't be more excited about it! A really big thanks to all those who have helped in this forum along the way! Some quick tips from my experiences (forgive me if any are repeats from other threads): -How to get bitcoins: Coinbase. Links with your bank account, very easy to setup and use. If using Coinbase to fund your BTC's, BE PATIENT! They will deliver. My experience was that it took 5 business days before my first BTC arrived. Now that I am verified, I can add more each day. -Wallet: I highly recommend using bitcoin-qt. It is very easy to download and setup/encrypt. The way I view this wallet is the same way I would view a very important file I would not want to lose. Backup on USB, Cloud, and offline just in case. Use a STRONG password for encryption! Make it meaningful to you! -With bitcoin-qt - GIVE IT TIME to download the block chain. It took me a day or so to figure out what this whole deal was and why it took so long to download, but it is essentially the public ledger of all bitcoin transactions ever. My experience is that it took about a day on my computer to fully download the block chain then everything was great. -Dipping toes into other cryptocurrencies - Using BTC-e is EXTREMELY easy and I would highly recommend. Sign up for BTC-e with an e-mail address backed up by 2 Form Authentication and again, strong password. I was able to transfer some BTC very easily, but it did take about an hour to transfer. Once there, any trade to other cryptos happens instantaneously. Be sure to read information about any fees with your buy or sell orders. If dipping toes into something like Litecoin, be sure to get the litecoin wallet on your computer (litecoin-qt). Essentially the same as the Bitcoin-qt wallet. Basically, I couldn't be happier with my experiences so far. For those getting anxious about getting into this currency, I think the best thing that could have happened to me was the wait time to get the first BTC. This has given me the necessary time to do all research needed to feel competent with BTC. So, look at your downtime as opportunities to research. If you are still feeling impatient, consider why you are transferring funds to BTC. We are all (still) early adopters in something with much promise. Sure, the price could get higher in 2 weeks, but if you believe in the promise of this, consider where it might be in 2 years!
I have started seeing paper wallet vendors pop up everywhere. Just a friendly reminder, if you didn't generate the keys and print the wallet yourself then it is not your wallet. It is someone else's wallet. I haven't looked because I can graphic design well enough for myself, but if these guys are selling blank pieces of pretty paper with a white square or two for you to print the QR codes in yourself, then that's great. But from the looks of it these are pre-generated addresses that you don't own because you didn't generate them. Sure, they "delete the keys from memory", "generated on a machine not connected to the internet", and so on... but that's only as good as their word. If people are that stupid I suggest everyone with the capability start selling paper wallets they generated, but keep the private keys (and promise your customers you "delete them after printing" or whatever you need to in order to satisfy their concerns. After a year of selling them, load all the private keys, copy the btc to your own wallet, and retire somewhere with a new name. Most of these victims will not realize the coins are gone for years, after all the paper wallet is safely stored in their safety deposit box... right?
Can you guys help me choose between Armory and MultiBit? I want to: 1. Install either of these as a wallet on a Mac that has never and will never touch the internet. 2. Be able to do offline transactions. 3. I will be adding/sending to my offline addresses as I go. Im unsure whether I can run Armory without having to first connect to the internet (and run QT), and Im also unsure whether I can do offline transactions with MultiBit. Are there any other positives/negatives that Im missing with either of these? In the interest of building a completely secure set-up, I would appreciate any help you guys can give me. Getting goxxed of my hard-earned coins is my worst nightmare. EDIT: I just donated to MultiBit as Ive been using them on my 'online' pc for a while now. Love how easy it is to do this :)
What is the best client to use for storing bitcoins, and is it worth making a paper wallet?
I have recently put a good amount of money into bitcoins, and I just want to make sure that all my coins are safe and backed up properly. According to this site it looks like bitcoin-QT is the way to go, but what are your recommendations?
This is getting awkward. Last night, 31st of March, 21:32 (GMT +1) 0.5602 BTC were transferred to "1FmMasfuEE6wtpzdWiVnDynfJ5tyyVbhP3". This was almost 100% what was stored in said wallet. I have full AV, there's 0 spy and/or malware on this computer. What the hell?!
yes, it was still running 0.8.6 apparently, don't know if this could have been an issue, and just updated it to 0.9 (latest)
Hey folks! Which app do you use as a bitcoin wallet? I've found a new one which I can use for my smartphone as an app. It's really useful and easy but I want to know your opinions about it. Have you tried a CoinSpace?
I can not get the hot version of Armory to run on Windows. It crashes every time while trying to build the database. I uninstalled and downloaded a new copy and it does the exact same thing. This whole offline wallet thing is a one gigantic pain the butt hole. It has taken days of learning how to boot from USB and to use Linux, switching USB's back and forth going on and off line and switching between windows and Ubuntu booted from USB, which is a huge pain in the ass by itself. Then a whole day of downloading the entire blockchain while my computer chugs along and runs like shit. Now in the end the buggy crap application won't even finish loading up and it looks like I will have to scrap the whole process. And apparently this is what is required to keep from having to trust an online service with your investment. I would suggest people hold back investing in Bitcoin for the time being, unless and until the software required to securely use the protocol matures beyond 2.0 GPA undergraduate, senior-project level work.
I couldn't figure out why my laptop kept going to sleep today till I finally realized that the Bitcoin client is probably overheating my CPU. I had no problems over the weekend, even though it took all of it to download the massive block file. But today, the client is re-indexing the blocks on disk (can't recall the error that came up), and ramping up to >90% of my dual-core laptop CPU, causing it to overheat and go to sleep several times today. Anyone else have this experience or have suggestions?
Should I keep my bitcoins in coinbase or bitcoin-qt?
Hi All, I was wondering what the best way to store a small number of bitcoins is. I buy my bitcoins on coinbase, and from my understanding, if I keep my bitcoins in my coinbase wallet, the only way I would lose them is if someone gets in my account or the coinbase website crashes. Is this correct? Now, if I send them to my bitcoin-qt address, which is encrypted, then make back ups of my wallet and make several copies of the .dat file, will this be very secure as well? Why do people find say that bitcoin-qt is "for newbies" or that it may not be that secure? What could go wrong with bitcoin-qt?
Because cold wallets, such as those stored offline in a text file as I keep recommending in my standard advice below: All you need is a text file to put your wallets in, like this example from https://walletgenerator.net/?currency=Dogecoin 1,"D7WBUpdgLRtG6WyPsqjhaKiJR65X8ZGnkZ","6KieLMW1poAzNVnmLuQZqA262gxEQ51eLGdDK8e2GL2B4LHCKKb"2,"DM8LT16d49zHr8ByXbUwZb9UBXDGMaZRdc","6Ktgxdv6vN9v2bDHwcJBBb3oMRAgXJumESzBnxaXUSGFZoq6pWQ"3,"D5UCa51AfxjtVHQ46oYXe2YfkctTeLXPhx","6L2WSPWadRYCwt2L1CxH6zC7PoTYY3KyjxdiUoCqi5eyq6hQKvj" Use https://coinb.in/#settings to move coins. Download both sites and run them offline. Use https://bitinfocharts.com/dogecoin/ to check balances and transactions. See http://www.mocacinno.com/blog/create-sign-broadcast-transactions-using-coinb/ for coinb.in tutorial. And read the ELI5s (and my history) for more info. Are without doubt THE SAFEST way to store your coins. Plus, they consume no resources. No bandwidth, no network stress for every node we have, no storage of 20Gb+ blockchains, no weeks of waiting for things to sync, no tearing your hair out and posting desperate pleas for help, and most importantly, no coins irretrievably lost because you or your client screwed up.
Wallets, ALL WALLETS are nothing but numbers. Very large numbers, but fundamentally no different from “7”, “42”, “911” or a phone number. They cannot be created nor destroyed, and you either know them or you don’t. Anyone who knows a key can use it to spend any coins it controls. Anyone who doesn’t know it, can’t. Don’t be the guy who doesn’t know his own keys. Keep them safe. Make copies. Keep those safe. Don’t let your friends, kid brother or random burglar find them, but don’t lose them either. The only other thing you need for a fully functional wallet is a way to spend coins. Coinb.in is such a way. There are others, such as DogeCoinMultiSig.org which tomcarbon built. Oh, and you can and should download it and run it locally.
The default entry point for coinb.in is https://coinb.in/#settings because this settings page is very well hidden. Its in the tiny gear wheel on the Broadcast page. Looking across the top of the page, you can see
We’re only going to use three of these. New, Sign, Broadcast. Now, keep in mind that coinb.in is an old Bitcoin tool which tomcarbon added Dogecoin to. Sometimes it thinks its dealing with Bitcoin still, so if you see anything odd, go and make sure you’ve selected Dogecoin in the Settings page.
This tool should be the only place you spend coins. Sure, some clients may look more convenient, but they all suffer from a very big coin-losing flaw. Whenever you split a UTXO, they create a new wallet to send the change to. And they DON’T TELL YOU! This means unless you back up after every transaction, you run a high risk of finding all your coins have ‘disappeared’ from your wallet, and you don’t recognise where they went. So if you use a client for the convenience as well as a text list of your wallets, you won’t know to add a new wallet to your masterfile. Its best to ditch the clients entirely.
Now we come to the nitty-gritty. Lets use those three wallets above and assume that #1 is the source, #2 the destination and #3 the change wallet. Note that these won’t actually work, as none of them have ever been used, but they will do as examples. New Transaction Located at the bottom of the New menu, this will give you a page to enter your wallets and amounts. In the top field, you enter your source address or Key. If you use the key, it will calculate the address when you click the Load button, which should match what you expected. Note that Load only brings in the first 100 UTXOs. This is so that you can retrieve coins from high-volume wallets which would kill any client. Coinb.in is in fact the ONLY WAY to do this, as even QT falls over around 600 UTXOs. You will see the total balance that was loaded in the Transaction Fee field. And also in the Inputs tab, where you can go to adjust which UTXOs to spend. Now you need to add the wallet(s) and amounts to send to them. Lets suppose the source contained a single UTXO for 1,000 Doge. You want to send 500 of them. So you would enter the #2 address in the Address field, and 500 in the Amount field. The Fee now changes to 500, which is not what you want. So you click the + button to bring up a new line, enter the change address and the other 500, making the fee zero. And you’re done. Check that the Fee is indeed zero. Check that the amounts shown in the Outputs and Inputs tabs match exactly.
THIS IS CRITICAL!
There is a bug which will send all the coins to the miners if the Outputs exceed the Inputs. I would have expected the Fee to show as negative in such a situation, but it doesn’t. BE WARNED! Once everything looks right, hit the Submit button. This will give you a block of hex code. Copy it. Sign Go to the Sign tab and paste it. Add your private key for the source wallet and click Submit. Note this can be done offline for safety. This will give you another block of hex, the SIGNED transaction. Broadcast Copy this and paste it in the Broadcast tab and click Submit. That’s it. Your coins are on their way. Make a cuppa and settle in while they arrive in a minute or three. Note: All fields retain their values unless you refresh the page! This can be a boon when doing multiple transactions, such as when emptying a huge wallet. But it can also be a trap for the unsuspecting. Refresh or close the window when you’re done.
Who should use this? Absolutely EVERYONE! Even if you’re wedded to your client in some satanic blood-contract, you should still know how this works, because sooner or later you’re going to have a problem you can’t fix without it. Definitely download the site and store it on every device you have. On every USB backup of your wallets. On your phone (well, except iOS which doesn’t do local HTML), etc, etc, etc. Oh, and if you’re a programmer SmartyShibe, do consider improving the code over on GitHub.

There is a discussion about nodes that came up today, where it seems I'm discouraging people from running the full QT/Core client. Yes and No. What I'm trying to make sure people understand is how things work, and that it is NOT mandatory to run a client in order to use Dogecoins (and yes, I realise that browser-based tools like coinb.in and wallet sweepers are 'clients' by strict definition). That said, more nodes is absolutely a good thing for the network. Preferrably full nodes. How do you run a full node? Just run Core/QT and open up Port 22556 on your router so it can connect to more than 8 peers. What will it cost you? You need your machine to be on 24/7/365, you need enough storage for the full blockchain (currently about 20Gb. Bitcoin is over 120Gb) and enough bandwidth to keep it in sync and share blocks with peers. A couple of Gb a month, most likely. This is best done with a desktop on a wired broadband link. Or maybe a hosted VM in the cloud. :)
EDIT 2017-01-09: Wallets WITHOUT Clients
Since I started helping people on /BitcoinBeginners, I'm getting a lot of questions about how to use wallets without running clients or trusting third parties. So here are a couple of resources that will make that possible, and not just for Dogecoin: Multi-Coin Wallet GeneratorNow supporting 129 currencies!Coinb.in Start by setting the currency, found in the gear wheel in the Broadcast tab. Dogecoin Wallet Sweeper Redeem 'paper' wallets containing up to about 100 UTXOs. Bitinfo Charts My favourite block explorer, handles a bunch of cryptos. Using these resources, it is possible to hold, receive and spend coins in various currencies, without having to run QT or a 'lite' client. You can also download and run the pages on your own device.
EDIT 2016-11-23: SEMANTICS about MINING! :P
Even though there is already a section on mining below, it has been suggested given the huge number of posts on the subject that this needs to be made clearer. Since people get their panties in a twist over the word 'dead', lets change that...
MINING IS DEAD!
MINING DOGECOIN IS UNPROFITABLE!
Put simply, there is no way to mine Dogecoin and make a profit because of the massive hashpower provided by industrial-scale Litecoin miners. Mining Doge directly stopped being viable when our hashrate exploded with the introduction of AuxPoW. Mining with CPU's and GPU's died when ASICs were introduced. And mining with a laptop WILL kill your laptop and cost you a fortune to repair or replace. Mining Litecoin with an exchange that also mines Doge and others will earn less than the electricity consumed, and you won't recover your costs. Probably ever, but certainly not in any reasonable time. Mining other currencies may be a thing, but that's beyond our scope here. This is /Dogecoin, not /GetRichMiningCryptos after all. If you want to mine the newest scamcoin for fun and profit, look elsewhere for advice. :/ Oh, and most important:
READ BEFORE YOU POST!
At any given time, there are half a dozen posts on the frontpage just like the one you're about to write, where the answers have already been given. Read them. Don't make people waste their time repeating themselves because you were too lazy to bother reading stuff. :P So there I was, having a quiet Sundy arvo bludge, as you do, when 42points turned up on Facebook and asked me to write a new sticky post for /dogecoin. Why would he do this, when he should be having a bludge himself, I hear you ask? Well, seems he was doing exactly that, and wanted to fob off the work he’s too slack to do himself. ;) Ah well, being a sucker for punishment, I’ll grudgingly oblige I guess. OK, first things first.
A client is a piece of software you keep on your computer which holds one or more wallets. Here are the current client versions. If you're using an older client please upgrade to the newest version prior to sending/receiving coins. Backup! Backup! Backup your wallet.dat file or private key so you can import them into the latest version of the client.
Be warned that unless you’re running Core (aka QT), you could have issues with wallets containing lots of UTXOs (Unspent Transaction Outputs - Where your coins REALLY live). Go read the ELI5 below, and keep a close eye on your transaction counts. If you DO run Core, realise that all full clients, regardless of the coin, require a copy of the blockchain and must keep it up to date. This will cost you time, storage space and bandwidth. You can save a little by downloading the bootstrap file though. I haven’t checked how recent this one is, so let me know if you find a more current version.
OK, so next, grab this wallet generator. Even if you plan on running a client(s). Because a) it does many, many cryptocurrencies, and b) you WILL need wallets at some stage over and above what you keep in your clients. Just be sure to run it locally (and offline if you’re truly paranoid).
Oh, and here’s a simple way to keep track of all your wallets using HTML. You can grab the source and modify it, then upload it wherever you need to suit your needs. You will also want a separate file with your private keys, but don’t upload that one anywhere, because if you lose your keys or someone else gets access to them, you will lose your coins.
Next, be aware that there are online wallets available. While any wallet you don’t own the keys to isn’t actually yours, and therefore isn’t safe, the following are safer than most. Dogetipbot of course is used daily by shibes on Reddit. Block.io uses multisig and gives you Doge, BTC and LTC wallets as well as testnets, and Dogechain gives you your private keys (and also offers a wallet sweeping service).
Exchanges also offer wallets, of course. Not that you should use them to store your hard-earned coins, because they can and do get hacked with monotonous regularity. But at some stage you’re going to want to trade, or hold a few uncommon coins. You could do worse than these three:
And then there’s the obligatory question of mining. Put simply, mining is for all intents and purposes dead, and has been for a long time now. The costs are greater than any possible returns. But, if you insist on doing it anyway, maybe because you inherited a miner, you can earn about 0.01 LTC/day per MH/s merge-mining at Litecoinpool. That’s about 4 cents. :(
Shibes sometimes complain that the devs are not as active in /dogecoin as they used to be. You can find them on IRC, slack or their very own sub if you need them though. Or poke sporklin, who can often help.
You can of course ask any questions here, or post them in the sub. However, do try searching first, because I guarantee every possible question has been asked many times before. And you should also subscribe and hang out in /dogeducation occasionally. There’s much awesomeness there.
From peoplma I was wondering if you could add just a couple things. A link to the coinomi android wallet, it's probably the best one out there. And a sentence somewhere along the lines of "if you need help with any dogecoin software you are welcome to make a post, but PLEASE include your OS, version number of the client, and any relevant transaction IDs that you are willing to share" if you can fit that in somewhere. Also, if you want to link to Prohashing, I'm pretty sure it's the only Scrypt mining pool that will actually pay out in doge. The others I know of pay out in litecoin or bitcoin. And it's a profit switching multipool, so gives a better return than just mining ltc/doge. And there's these two wiki articles I thought would be helpful to link /dogecoin/wiki/technical for those technically minded newbies or intermediate users who want to dig a little deeper. And maybe a link to /dogecoin/wiki/dogecoincoreguide next to the link for dogecoin core. From pts2002 Finally a proper sticky post! Here's some other stuff you could add: zpool.ca mining pool - You can get paid in pretty much any coin, and you can mine in multiple algos (currently mining lyra2v2 with my GPU). Doing about 500Ð/day shapeshift.io exchange - My favourite exchange, quick and easy. No registration required! Also, you should add some blockchain explorers! chain.so - Support for bitcoin, litecoin and doge. dogechain.info - Official blockchain explorer. Includes a wallet (already mentioned). Live update currently not working (?) EDIT: Here's another thing I found! preev.com currency value calculator - Easy way to check the value of your dogecoins (or bitcoins, or litecoins, or peercoins)!
