Syscoin Platform’s Great Reddit Scaling Bake-off Proposal
https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44 We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution! Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality. Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining. This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.
Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.
Syscoin + Matic Integration
Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both. Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.
Total cost for these 100k transactions: $0.63 USD See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing: ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37) Syscoin price: $0.11 Snapshot of live fee comparison chart Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions. Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.
Tools to simplify using Syscoin Bridge as a service with dapps and wallets will be released some time after implementation of Syscoin Core 4.2. These will be based upon the same processes which are automated in the current live Sysethereum Dapp that is functioning with the Syscoin mainnet.
The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms. The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.
Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.
Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Probabilistic and interactive
99.9999% security assurance within 10 seconds
Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus
Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.
Syscoin 3.0 White Paper (4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)

Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.
Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask. Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2. Current supported wallets Syscoin Spark Desktop Syscoin-Qt
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

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.
The last month in the world of Mousecoin has been HUGE! There have been many changes, the addition of new awesome ways to earn MIC3 including ourFaucetspage and thePhoneumGames. We have also seen the launch of ourCommunity Membership, which entitles each registered user to receive up to 200,000 MIC3 per month. We hope you are all keeping safe and are happy to provide you with our Mousecoin Network May 2020 Report.
MOUSECOIN IN GAMES!!
FINALLY, after months of negotiation and with the help ofPhoneum, Mousecoin has partnered withPhoneumto be included in two of the most popularPhoneumcrypto games currently available.We have added a newGamespage, whiche features all the information and link for the games, with more to come.Here is the run down:
📷 Crypto Treasures is a game, where players complete various quests, trivia and mini games to unlock Gold (in-game currency), Treasure Chests, Items, Collectibles, and various Crypto currencies, including the featured Mousecoin (MIC3).
📷 Visit a new type of planet, one that allows you to earn real cryptocurrencies while playing a beautiful and futuristic game. The main objective is to extract the valuable resources of the planet: Crystals. There is a special machine designed specifically to dig up the Crystals automatically and deliver them to you. All you have to do is activate the Digger and after 4 hours, it will have the resources ready to be claimed.
Earn up to 200,000 MIC3 Per Month!
At the beginning of last month we began establishing ourCommunity Membershipwhich offers all registered Mousecoin Members a share of the rewards earned from theCommunity Fundjust for being a member and following Mousecoin on all of oursocial media.As we come to the end of the first month we are currently in the process of checking all registrations and working out payments. We have also updated the profile page to include a Member News tab, Verified Notifications for each Social Media and a Monthly Payment History section. We are currently working on verifying all accounts registered before 1/6/2020, and should have all of these processed in the next few days, with all payment going out before the end of the week.
Become a part of the Mousecoin (MIC3) Community.Membership is FREE and it comes with HUGE bonuses!!
Just a reminder for the community and also for any new members, we have added aWallet Setup Guidespage, which takes any first time user of Mousecoin step-by-step through the process of installing their Mousecoin wallet and getting it online. The guide uses the latestblockchain snapshotfound on theWallet DownloadsPage in the example explanation meaning that all new members of the Mousecoin community will be able to get their wallets online faster as the sync time should be minimal. We will be updating theblockchain snapshotat least once every month to ensure that people have access to the most up to date blockchain info. The latestblockchain snapshotwas performed on the 1st June 2020. The wallet version is currenty V184.108.40.206, with future releases of the Mousecoin wallet coming soon If you are new to crypto currency or just after a bit of guidance setting up the Mousecoin wallet, check out ourWallet Setup Guides 📷Windows 📷Raspberry Pi 📷Wallet & Blockchain Snapshot Download (UPDATED 01-06-2020)
POS & STAKING
In the last month we asked the community if they would be interested in being a part of a Community Staking Pool. After investigations into this finding security flaws in most platforms, as well as the lack of interest from members of the community we have decided to not go ahead with the Community Staking Pool. While we understand that there are members of the Mousecoin Community that are unable to stake themselves for whatever reason, and that there are a number of staking platforms that offer pool staking for MIC3 to help these people stake, we will not officially be supporting any staking platforms.We ask all Community members using these or thinking about using these to keep in mind that any MIC3 hosted on these platforms is not in their wallets, and therefore not controlled by them. Do proper investigations into any platform that you use for this as there is always the possibility of loss. We encourage all members of the Mousecoin Community to stake from their own wallet (where possible) as this helps us to secure the network. If you need help setting up your wallet, go to ourWallet Setup Guidespage for step-by-step guides on setting up your Mousecoin wallet.
We have updated the Mousecoin (MIC3)FaucetsPage: To make things clearer and we will be adding more faucets soon!
Last month we saw the edition of theUSDT/MIC3pair tonanu exchange. In our efforts to increase exposure of Mousecoin, we are still attempting to list on bothATAIXandUnnamed.Exhchange. ATAIXWe have risen to 18th position in the voting list onATAIX, but we still need your votes. Remember you can vote every 24 hours for this listing, and you can share in 125,000,000 MIC3 📷 Unnamed.ExhchangeThe exchange listing forUnnamed.Exhchangeis 0.05 BTC.For anyone unfamiliar with the exchange there are two ways that you can donate to the listing: 1. If you are already a member of, or wish to be a member ofUnnamed.Exhchange(and why wouldn’t you), you can put funds towards our listing by tipping us through the trollbox (Mousecoins). If you wish to be a member ofUnnamed.Exhchange, you can register here:https://www.unnamed.exchange/Login/Register 2. You can also donate to the listing fee through the following addresses:BTC – bc1qmaqzhfqcw0urva0rtgfz5qvq4rw7kdnp6j7754LTC – ltc1qc775eeftdde2jrevnyukrd2w9853jy5gmtv6rnDOGE – DEnBpriaFnKiNeBv6Q7MVxMg5hLv5urQFgUTIP – AUTyu2JhGAaCkM3KAmeBopto2bNBchNJfE If you would like to donate in another crypto available onUnnamed.Exhchange, we have opened up the chat on the Discord channelHEREto assist with this. Please request the address and we will provide it for you.ANY AND ALL DONATIONS ARE WELCOME!!This is a good exchange and getting a listing her should help lift the profile of MIC3. We will be reporting balances to the discord channelhttps://discord.gg/cYuA8FA
📷 In the last month theCommunity Fundhas undergone a huge amount of change. We have completely moved all of our remaining balances away from 4Stake, with the MIC3 going to theCommunity FundMIC3 account and the remaining crypto’s towards out listing onUnnamed.Exhchange. TheCommunity Fundpage on the website has also been updated to reflect all of the changes.It is an exciting time for theCommunity Fundas we have now reached a balance that will sustain itself. This is why we have introduced the Community Member payment, and are able to sustain the faucets we have onhttps://erex.io/freecoin/and in thePhoneumGames. There is still more to come! 📷

Add freedesktop.org desktop file and icon set #1438 (@a123b)
There is a discussion about nodes that came up today, where it seems I'm discouraging people from running the full QT/Core client. Yes and No. What I'm trying to make sure people understand is how things work, and that it is NOT mandatory to run a client in order to use Dogecoins (and yes, I realise that browser-based tools like coinb.in and wallet sweepers are 'clients' by strict definition). That said, more nodes is absolutely a good thing for the network. Preferrably full nodes. How do you run a full node? Just run Core/QT and open up Port 22556 on your router so it can connect to more than 8 peers. What will it cost you? You need your machine to be on 24/7/365, you need enough storage for the full blockchain (currently about 20Gb. Bitcoin is over 120Gb) and enough bandwidth to keep it in sync and share blocks with peers. A couple of Gb a month, most likely. This is best done with a desktop on a wired broadband link. Or maybe a hosted VM in the cloud. :)
EDIT 2017-01-09: Wallets WITHOUT Clients
Since I started helping people on /BitcoinBeginners, I'm getting a lot of questions about how to use wallets without running clients or trusting third parties. So here are a couple of resources that will make that possible, and not just for Dogecoin: Multi-Coin Wallet GeneratorNow supporting 129 currencies!Coinb.in Start by setting the currency, found in the gear wheel in the Broadcast tab. Dogecoin Wallet Sweeper Redeem 'paper' wallets containing up to about 100 UTXOs. Bitinfo Charts My favourite block explorer, handles a bunch of cryptos. Using these resources, it is possible to hold, receive and spend coins in various currencies, without having to run QT or a 'lite' client. You can also download and run the pages on your own device.
EDIT 2016-11-23: SEMANTICS about MINING! :P
Even though there is already a section on mining below, it has been suggested given the huge number of posts on the subject that this needs to be made clearer. Since people get their panties in a twist over the word 'dead', lets change that...
MINING IS DEAD!
MINING DOGECOIN IS UNPROFITABLE!
Put simply, there is no way to mine Dogecoin and make a profit because of the massive hashpower provided by industrial-scale Litecoin miners. Mining Doge directly stopped being viable when our hashrate exploded with the introduction of AuxPoW. Mining with CPU's and GPU's died when ASICs were introduced. And mining with a laptop WILL kill your laptop and cost you a fortune to repair or replace. Mining Litecoin with an exchange that also mines Doge and others will earn less than the electricity consumed, and you won't recover your costs. Probably ever, but certainly not in any reasonable time. Mining other currencies may be a thing, but that's beyond our scope here. This is /Dogecoin, not /GetRichMiningCryptos after all. If you want to mine the newest scamcoin for fun and profit, look elsewhere for advice. :/ Oh, and most important:
READ BEFORE YOU POST!
At any given time, there are half a dozen posts on the frontpage just like the one you're about to write, where the answers have already been given. Read them. Don't make people waste their time repeating themselves because you were too lazy to bother reading stuff. :P So there I was, having a quiet Sundy arvo bludge, as you do, when 42points turned up on Facebook and asked me to write a new sticky post for /dogecoin. Why would he do this, when he should be having a bludge himself, I hear you ask? Well, seems he was doing exactly that, and wanted to fob off the work he’s too slack to do himself. ;) Ah well, being a sucker for punishment, I’ll grudgingly oblige I guess. OK, first things first.
A client is a piece of software you keep on your computer which holds one or more wallets. Here are the current client versions. If you're using an older client please upgrade to the newest version prior to sending/receiving coins. Backup! Backup! Backup your wallet.dat file or private key so you can import them into the latest version of the client.
Be warned that unless you’re running Core (aka QT), you could have issues with wallets containing lots of UTXOs (Unspent Transaction Outputs - Where your coins REALLY live). Go read the ELI5 below, and keep a close eye on your transaction counts. If you DO run Core, realise that all full clients, regardless of the coin, require a copy of the blockchain and must keep it up to date. This will cost you time, storage space and bandwidth. You can save a little by downloading the bootstrap file though. I haven’t checked how recent this one is, so let me know if you find a more current version.
OK, so next, grab this wallet generator. Even if you plan on running a client(s). Because a) it does many, many cryptocurrencies, and b) you WILL need wallets at some stage over and above what you keep in your clients. Just be sure to run it locally (and offline if you’re truly paranoid).
Oh, and here’s a simple way to keep track of all your wallets using HTML. You can grab the source and modify it, then upload it wherever you need to suit your needs. You will also want a separate file with your private keys, but don’t upload that one anywhere, because if you lose your keys or someone else gets access to them, you will lose your coins.
Next, be aware that there are online wallets available. While any wallet you don’t own the keys to isn’t actually yours, and therefore isn’t safe, the following are safer than most. Dogetipbot of course is used daily by shibes on Reddit. Block.io uses multisig and gives you Doge, BTC and LTC wallets as well as testnets, and Dogechain gives you your private keys (and also offers a wallet sweeping service).
Exchanges also offer wallets, of course. Not that you should use them to store your hard-earned coins, because they can and do get hacked with monotonous regularity. But at some stage you’re going to want to trade, or hold a few uncommon coins. You could do worse than these three:
And then there’s the obligatory question of mining. Put simply, mining is for all intents and purposes dead, and has been for a long time now. The costs are greater than any possible returns. But, if you insist on doing it anyway, maybe because you inherited a miner, you can earn about 0.01 LTC/day per MH/s merge-mining at Litecoinpool. That’s about 4 cents. :(
Shibes sometimes complain that the devs are not as active in /dogecoin as they used to be. You can find them on IRC, slack or their very own sub if you need them though. Or poke sporklin, who can often help.
You can of course ask any questions here, or post them in the sub. However, do try searching first, because I guarantee every possible question has been asked many times before. And you should also subscribe and hang out in /dogeducation occasionally. There’s much awesomeness there.
From peoplma I was wondering if you could add just a couple things. A link to the coinomi android wallet, it's probably the best one out there. And a sentence somewhere along the lines of "if you need help with any dogecoin software you are welcome to make a post, but PLEASE include your OS, version number of the client, and any relevant transaction IDs that you are willing to share" if you can fit that in somewhere. Also, if you want to link to Prohashing, I'm pretty sure it's the only Scrypt mining pool that will actually pay out in doge. The others I know of pay out in litecoin or bitcoin. And it's a profit switching multipool, so gives a better return than just mining ltc/doge. And there's these two wiki articles I thought would be helpful to link /dogecoin/wiki/technical for those technically minded newbies or intermediate users who want to dig a little deeper. And maybe a link to /dogecoin/wiki/dogecoincoreguide next to the link for dogecoin core. From pts2002 Finally a proper sticky post! Here's some other stuff you could add: zpool.ca mining pool - You can get paid in pretty much any coin, and you can mine in multiple algos (currently mining lyra2v2 with my GPU). Doing about 500Ð/day shapeshift.io exchange - My favourite exchange, quick and easy. No registration required! Also, you should add some blockchain explorers! chain.so - Support for bitcoin, litecoin and doge. dogechain.info - Official blockchain explorer. Includes a wallet (already mentioned). Live update currently not working (?) EDIT: Here's another thing I found! preev.com currency value calculator - Easy way to check the value of your dogecoins (or bitcoins, or litecoins, or peercoins)!
I am currently trying to set up blackoin on raspberry. Community members asked for a tutorial to compile it, so I will start with this here. Maybe in the future it would even be possible to turn it into a headless (=without screen and keyboard) image to put on an SD card and just boot up the wallet. I used the latest Blackcoin Lore by janko33 for this process, however it should be quite the same with the "original" core wallet by rat4/johndolittle. Blackcoin Lore is not deemed as stable as it is still in beta, so it's up to you what source tree you take. Please be also aware, that compiling on a small computer like raspi can take a while. Please also note that Lore is still in beta. The names in the archive are still "bitcoin". There is an update comming where the naming is correct and also maybe a few bugfixes. ** Tutorial: ** You first need to get raspbian. The lite image will work, it's a small version of the operating system without a graphical interface, so you will need ssh to operate it. The image is 294 MB but you will want to have a bigger card. 2GB is certainly too small, better get 16 or even 32GB - you also will need space for the blockchain! To install it I followed this guide https://hackernoon.com/raspberry-pi-headless-install-462ccabd75d0 Get the raspdian image file from: https://www.raspberrypi.org/downloads/raspbian/ Also get Etcher from https://etcher.io/ Etcher is a tool to write img files to an SD card/USB-stick. After writing, open the card in your explorer and add a file "ssh". The file sould be empty and just be called "ssh" (not ssh.txt or something). It will tell raspi to activate ssh on boot. Then boot up your raspi with the card and plug it into your network. Consult your router's LAN-page to find the device, it should register to your router as "raspberry" or so. Open up Putty and login to your raspi using pi as username and raspberry as password. After login you can configure your raspi, please read the guide linked above for more details. Note: One important thing that you should configure is your timezone! Use
Go to 4. Localisation Options and set the time to your timezone. If your time is way off, you would get troubles with staking, so make sure you always have the time set right! After you got everything set up, get the build environment ready:
sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils #Installs alot and can take a while git clone -b Blackcoin-Lore https://github.com/janko33bd/bitcoin Blackcoin-Lore cd Blackcoin-Lore cd depends make -j 6 HOST=arm-linux-gnueabihf cd .. ./autogen.sh ./configure --prefix=`pwd`/depends/arm-linux-gnueabihf
# note: ` = is a "backtick" not an apostroph. It causes the outpupt of "pwd" being inserted there
make -j 6 # -j n tells the compiler to use more cores, speeds that up a little (n = 1.5*cores installed) sudo make install
This should compile so far. Update: Lore does not need Berkeley DB 4.8 to be installed, so just go with the DB provided by the repository works (libdb++-dev). (Thanks patcrypt) After compile you can run the wallet with
And after it synced you have bitcoin-cli to control the wallet. Issue: Synching blocks takes an awfully long time on raspi for some reason, even with Lore (that syncs blocks in a few hours instead of a whole day on a normal computer). If anyone knows how to speed up that process, please let us know! This thread is a WiP. Please post all issues and errors here, I will then edit the OP to make it into a real, working tutorial. On a note it was mentioned, that using an USB-stick here instead of a card would make sense since the cards are more prone to failure than USB-sticks. I will include setting it up on USB in a later version of this tutorial. Some tips and tricks Since compiling takes a longer time, it is recommented to run it in the console in a screen. Screen is a terminal tool that supports multiple windows in the same shell and, most important, detaches when your ssh connection breaks. Using screen you can simply reconnect and use screen -r to attach to your running shell again. To use screen, you need to install and then start it before you start the whole build process within a screen-shell.
sudo apt-get install screen screen #Start install/build process here #Type [ctrl-a] [d] to detach from the screen and put it in the background #After reconnect type screen -r to jump back into your running shell
If you want to see your blocks being processed while the wallet syncs to the network, use the following command on a second shell (new Putty instance or screen window which you can open in screen with [ctrl-a] [c] (hit [ctrl-a] [n] to cycle through the windows in screen)
watch -n 5 lore-cli getinfo #This will execute the command "bitcoin-cli getinfo" every 5 seconds and thus display live update of your wallet info
How to use that thing? Here are a few helpful CLI commands, call them with lore-cli
help - Returns available commands help - Returns detailed help to a getinfo - Returns a descriptive information of your wallet, including balance getwalletinfo - Returns short information about your wallet, including balance, unconfirmed balance, immature balance, number of tx ect getaccountaddress 'raspi' - Returns an address for your wallet. If the account does not need to exist, it will be created with new address sendtoaddress - Sends to sendtoaddress substractfeefromaccount - Sends minus tx fee to getnewaddress - Returns a new address for each time you call the command. is optional
Further plans for this tutorial/project
Install on USB with a small boot image on SD
Planned: Web GUI to control your wallet easily from your local network

Guide: How to redeem and sell bitcoin diamond (bcd) from ledger nano s (Segwit)
I spent two days to figure this out but I think I know how to solve this, just currently stuck and need your help! I had btc stored on a nano s segwit wallet before the fork. Bitcoin diamond was forked from bitcoin on block #495866 (nov 24 2017) and launched the mainnet Jan 5 2018 (I think). There is currently very little information about this project and very little support on exchanges, wallets and mining. http://btcd.io The only light wallet currently have a splitting tool is Bither for Android but they do not support Segwit. If you had your btc in a segwit wallet before the fork you can't use this method. Otherwise follow this: https://steemit.com/bitcoin/@tiberiu/how-i-claimed-sbtc-super-bitcoin-from-my-paper-wallet Or this: https://www.reddit.com/BitcoinMarkets/comments/7oekie/guide_how_to_redeem_and_sell_all_bitcoin_fork/ You get 10 bcd for every btc and current price is 0.001 btc. That means you get $160/ forked btc which is 1% free money. Is it worth it? For me it is. You can use same method for both SBTC and BCD. Other methods can be used for BTX, BCX and BFX but have to wait for me. Need segwit support in Coinomi and/or Bither. In my BCD case it was a bit more complicated but hopefully possible.
Enter your ledger 24 word mnemonic. Select BIP49 derivation path. Find your btc address that contained btc right before block 495866, copy private key. Use a block explorer: https://blockchain.info
Find the tx ID that sent those btc and verify in bcd explorer if you have any bcd before you continue (click on the actual address will not work for some reason, shows empty). My tx had 3000 confirmations. http://explorer.btcd.io
Actually quite cool you can run Ubuntu on Windows 10! You can build for 32 bit as well but not when you have installed dependencies for x64. The last step will copy the binaries to your windows folder: "make install DESTDIR=/mnt/c/workspace/bitcoindiamond"
Run bitcoindiamond-qt in windows and let it sync with network. Took me 12h with fiber connection.
Go to help and open console. If your wallet is encrypted, decrypt for 10min using: "walletpassphrase your-wallet-passphrase 600".
Import old btc address as watch-only to check bcd balance. True means it will rescan the blockchain. Rescan took 1h with a decent PC (no SSD):
If you see your BCD balance, now Import your btc private key into the watch-only address. No need to rescan again, thus "false".:
Ok here is where I'm stuck. I can see my balance but it's not spendable. I also tried to import private key directly (with sync) with empty core wallet but balance is still zero. It does not pick up the transaction! Anyone know how to solve this? Rest of the guide when this is solved:
You should now be able to access your bcd!
Go to gate.io (register). Deposit bcd to exchange from bitcoindiamond-qt. Try small amount first, use a proper fee.

There is a huge surge in devices attached to the internet, known as the Internet of Things, and it is estimated that over 80 Billion devices will be connected to the internet by 2025, from industrial machines to devices in our home. The constant hacking and cyber attacks have increased not only the demand but the necessity of secure solutions. Our privacy and digital footprint are at risk. [b]Some examples where encryption plays a role: [b]Secure messaging - To make messages truly secure we need a process whereby a cryptography can be applied to encrypt transaction. [b]Secure calling - Secure calling is a process whereby the caller and the recipient of the call are identified and linked via a blockchain enabled cryptocurrency transfer, again creating public and private encryption keys making the call truly private. [b]Secure media storage - To safely and securely store media a process is required where 1.) Access to the media is encrypted via public and private keys of the person wanting to store the media. 2.) The media itself needs to be encrypted with a set of encryption keys and 3.) Media storage costs need to be paid via cryptocurrency [b]Secure browsing - To browse the internet securely we need to create a process of verification whereby nodes on the blockchain can verify websites as “safe”. Furthermore, the entire process needs to be encrypted as well. [b]Verification - This is one of the most important uses of a blockchain, we can verify websites as in the example above but also various other things such as identity, title and ownership, date stamps and source of products as with the verification of the source of agricultural or other products. These are just a few examples. All of this data needs to be encrypted as well. [b]“Smart home” security - Wi-Fi is often used for remote monitoring and control. Home devices, when remotely monitored and controlled via the Internet, are an important constituent of the Internet of Things - all needing encryption, otherwise, hackers paradise. [b]EOT in the future - The examples we mentioned above are only “scratching the surface” of where these technologies are applicable and who knows what will be invented in future. Google, Apple and Uber are all testing cars that drive themselves. A major issue with this technology is again the security aspect and the need to protect against hacking and who want’s to get into a spaceship to Mars that might be hacked or hijacked by ransomware? So the future for the [b]“Encryption of Things” – EOT, looks very interesting indeed and the role of crypto currencies in this will be major.

I've been doing a bit of research with the technology behind this coin. It looks like ALOT of research has gone into this tech, since about 2004 and shortly after a patent for this P2P system was quickly issued. Bitvault (https://swissbankinyourpocket.com/product/bitvault/) who are using the worlds first blockchain phone as a secure communication device and ultimately taking [font=Verdana][b]encryption[/b][/font] to the Internet Of Things (IoT) keeping our personal and business data secure. All this is done using [b]EOT coin [/b](Encryption of Things). In todays world insecure devices are rampant. Here are a couple of links about the CIA being able to use insecure devices to 'cause accidents' http://www.sandiegouniontribune.com/news/cyber-life/sd-me-wikileaks-cia-20170307-story.html and https://www.washingtonpost.com/news/innovations/wp/2017/03/08/what-we-know-about-car-hacking-the-cia-and-those-wikileaks-claims/ It's scary to think a legal entity could posses such power over life. Just the mere fact alone the governing authority can request phone records (e.g. txt msgs, voice msgs or eavesdropping) proves most if not all telecommunication companies do not encrypt, otherwise whats the point on requesting the information!? (legal or not). Commercially sensitive information needs to be protected and most importantly in my opinion our [font=Verdana][b]rights[/b][/font] and the privacy of all citizens of the human race need to be protected. From my understanding BitVault is a platform for reference data. This would be data that is stored for compliance reasons such as e-mails, invoicing systems and check imaging (e.g. high quality imaging for x-rays, MRI scans etc) and a prototype was developed in 2004. This would means massive amount of data storage is required with fail-safe systems so a authorised user could access this information very very quickly. Three goals were needed to be achieved: Low cost, high reliability/availability and simplicity. This is the birth of Bitvault via EOT. Bitvault ultimately stores immutable objects with each new version being updated and identified with a 160-bit key. System stability is very important and must be immune to failure sequences. Parallel repair via indexing is one of the many strengths Bitvault has been able to demonstrate. BitVault is a back-end system that uses [u][b]Applications[/b][/u] to catalog object ID's. Using a catalog utility and indexing within an application prevented scalability bottlenecking under heavy loads. Fast forward 3 years to 2007 a very important decision was to [u][b]decentralise[/b][/u] BitVaults system. This in my opinion is one of the fundamental principles of cryptocurrency - [u][b]No one entity or person has any control of the data stored and only the authorised user can access this info[/b][/u]. Ultimate Security and thus personal safety (see above articles CIA hacks). BitVault using applications have been able to use provable communication and data storage with ease of retrieval with vital security measures. BitVault is not alone in researching solutions for security for the IoT, such as Venti and the like are making progress, however, BitVault is 'head and shoulders' above the few competitors and are already offering practical working solutions on the market with huge scalability that is cost effective. Well Done BitVault, well done EOT your secret is out and let the world embrace. author=Story777 link=topic=2091616.msg21462424#msg21462424 date=1504428317] I have had a response in Slack and it has satisfied my questions. Thank-you. For everyone information here it is: The currency was created with 200 Million EOT total supply on 7 July 2017 [ we showed it to the community a London Fintech week with the demonstration of the BitVault - fintechweek.com ] 100 Million was pre-mined and another 100 Million are currently being mined, 1 block every 90 seconds @ 100 coins per block. So the pre-mined coins were listed on waves as a token so that it can create a market for the coins while we are working to get listed on other exchanges. The 100 Million coins listed were distributed in several ways. Firstly, this was not an ICO because our business is already funded via private capital. We wanted to get the currency distributed a widely as possible. So most of the initial coins were given away to a number of interested parties. We distributed this to our whole development team, business partners, employees as well as to the waves and other communities. So we did not sell all these coins for the current price, most of it was given away for free to people that have an interest in our products and business. The price now is formed by whoever owns these coins. The tokens on the exchange is really a representation of the currency and as such has value because it can be interchanged, just like Bitcoin and Ethereum are on the waves exchange. This whole process is explained on page 4 of the waves whitepaper, I think they call it an asset-to-asset exchange which makes it possible to list any asset that exist on waves. Unfortunately waves only has gateways currently for Bitcoin, Ethereum, Waves, Euro and USD, so we have to develop our own gateway, which will be available on Nov 1. So to clarify 100,000,000 tokens costing $190M were not sold. It is a combination of airdrops, private sales and sales on the exchange. Some EOT coins are needed because: "A lot of EOT will be distributed through our devices. For example our encrypted routers are pre-loaded with EOT, so we need that stock and it will be distributed that way". And with the response to tokens on the Waves Exchange "This is how Bitcoin works on waves: - They created 21 Million BTC Tokens.. When you deposit Bitcoin into waves account, you receive an equal amount of tokens which you can either trade or even sent via the waves blockchain to another user.. Once you withdraw your tokens are exchanged for BTC and you receive it back into your BTC wallet.. Exactly the same for USD or EUR - You don't send Euro's to another client on waves if you transfer - you send a token that represents EUR -- This works exactly the w0083". These are the answers I was looking for and make a lot of sense now. This is indeed an exciting project. :) It's time to trade.... Now I have one question left.... Is there anyone using NiceHash to mine this coin?? I keep being disconnected because of the difficulty being too low. Can any one help? [quote author=Shews link=topic=2091616.msg22876983#msg22876983 date=1507755312] EOT (coin) is now tradable on the CryptoBridge Decentralised Exchange, you can sign up below. Please note this is for the EOT COIN ONLY, do not send tokens to this dex. This is a secure means to trade with the backend being on a blockchain. It is still in beta stage but has been working flawlessly so far. If you'd like more info I will post their website link is below. https://wallet.crypto-bridge.org/?r=388691 You can sign up with a local wallet mode, meaning you are the only one with access to your keys, this is most secure. There is also the option to sign up with and account if you require access to you funds on the go. More info: https://crypto-bridge.org/
Details: I'm using the Litecoin Android mobile wallet. I broadcasted a successful transaction earlier in the evening. I then broadcasted another and none of the block explorers have seen it. It's been 1.5 hours. My wallet shows the reduced balance but still nothing shows up on the blockchain... Any ideas? UPDATE: I followed these instructions to import my private key into Litecoin-QT and was able to spend them from there: https://bitcoin.stackexchange.com/questions/17176/how-to-decode-private-key-from-android-bitcoin-wallet
QT wallet – Most of the crypto currency core wallets are developed using QT software framework. They are available for Windows, Linux and Mac. QT wallets are professional client and offers full function that’s available for a currency. Also they are heavy as it is known to download the complete blockchain to your local computer. We can import any Bitcoin address to core QT wallet. But the process is bit complicated and moreover you need to run full node and you need to re-scan the blockchain. It takes a lot of time and is not worth it. So instead of core wallet there are several third party wallets that supports watch-only feature. To name some: Armory wallet, Blockchain wallet (blockchain.com), Bit wallet, Electrum ... Drag the wallet file into the area above. Supports blockchain.info (wallet.aes.json) files. × Go to C:\Program Files (x86)\Bitcoin using Windows Explorer. In that folder, hold shift and right-click and select “Open command window here” In the command prompt, type bitcoin-qt.exe -rescan and hit enter. Now Bitcoin-Qt should start and rescan the blockchain to calculate the balances of the addresses in your wallet.dat file. I tried to import my private key from the BTC Core Wallet into another wallet because it doesn't work anymore, it says that there is no fund, even if it is 100%, as I can see on the Explorer.
