GROESTLCOIN DEVELOPMENT RELEASE

GRS BlueWallet iOS

What am I?

GRS Bluewallet is built with React Native and Electrum-GRS.

Features

• Multi-currency- GRS Bluewallet supports more than 20 currencies, including USD, AUD, BRL, CAD, CHF, CZK, CNY, EUR, GDP, HRK, INR, JPY, MXN, MYR, or RUB.
• Multi-language - GRS Bluewallet supports more than 20 languages, including Chinese, Japanese, Portuguese, Spanish, Indonesian, Russian, Ukranian, Italian, German, Swedish, Norwegian, French, Danish or Turkish.
• Export TXHEX - You can get your transaction HEX (TXHEX) without broadcasting it, and only do it with the relay of your choice.
• Be in control - On your Groestlcoin wallet your private keys never leave your device. You are in full control of your private keys. You can at any moment generate backups and export/import your wallets, with full control of what to do with your private keys.
• Multiple wallets support - GRS Bluewallet aims to support the maximum wallet standards. Currently supported: BIP44 (HD), BIP49 (HD SegWit), BIP84 (HD bech32, native SegWit), BIP39 Groestlwallet-compatible (m/0'/0/0), Legacy single-address, SegWit single-address (P2SH). You can have many wallets in a single app at the same time.
• HD wallets - The Hierarchical Deterministic (HD) key creation and transfer protocol (BIP32), which allows creating child keys from parent keys in a hierarchy. The HD Wallets will generate you different public keys for each transactions.
• SegWit - SegWit supported in P2SH-compatibility mode and bech32 Native mode. Segwit was a massive upgrade to the Groestlcoin Protocol released in 2017. You will find all wallets with SegWit enabled by default.
• Full encryption - On top of the phone multi-layer encryption, GRS Bluewallet can encrypt everything with an added password. Biometric security (touch ID, Face ID) is not safe, so you will have an additional password to encrypt your wallet instead.
• Plausible deniability - A custom made feature thinking about your personal security. GRS Bluewallet allows you to define a different password which will decrypt a fake wallet set up. For any situation you are forced to disclose your access or when you don't want or you can't show your real wallet.

• Bump and Cancel transactions - Ability to bump and cancel sent transactions with "Replace-by-fee" (RBF) and ability to Bump received transactions with "Child-pays-for-parent" (CPFP) on Native Segwit wallets (bech32/BIP84).
• Plug-in your Groestlcoin Full node new - Ability to plug-in your own Groestlcoin Full node through Electrum Personal Server (EPS), ElectrumX or Electrs. Don't trust, verify for a maximum sovereignty.

Groestlcoin Eclair 0.3.3

What am I?

Groestlcoin Eclair is a Scala implementation of the Lightning Network. It can run with or without a GUI and includes a JSON API.

Requirements

• Requires Groestlcoin 2.17.1 or greater. If you are upgrading an existing wallet, you need to create a new address and send all your funds to that address.
• Needs a synchronised, segwit-ready, zeromq-enabled, wallet-enabled, non-pruning, tx-indexing Groestlcoin Core node.
• Will use any GRS it finds in the Groestlcoin Core wallet to fund any channels you choose to open. Eclair will return GRS from closed channels to this wallet.
• You can configure your Groestlcoin node to use either p2sh-segwit addresses or bech32 addresses since Eclair is compatible with both.

Features

• Multipart payments
• Trampoline Routing Preview

Features

• Ability to create Lightning Network channels
• Ability to close Lightning Network Channels
• Completely manage all channel states, including exceptional ones!
• Supports both Mainnet and Testnet

C-lightning 0.8.2

What am I?

C-Lightning is a specification-compliant Lightning Network implementation built in C. It is a lightweight, highly customisable and standard compliant implementation of the Lightning Network protocol. C-Lightning only works on Linux and Mac OS and requires a local or remote instance of Groestlcoind (version 2.16 or above) that is fully synced to the correct blockchain.

Features

• We now support gifting mgro to the peer when opening a channel, via push_msat, providing a brand new way to lose money!
• Invoice routehints can be overridden using exposeprivatechannels: try setting to [] to eliminate all of them to fit your invoice in twitter messages!
• Wallet withdraw transactions now set nLocktime, making them blend in more with other wallets.
• Preliminary support for plugins hooks which can replace the default groestlcoin-cli with other blockchain querying methods (API may change in future releases though!).
• listforwards now records the outgoing short_channel_id, even if it wasn't possible to start forwarding.
• Plugins can set additional feature bits, for more experimentation.
• More than one plugin can register for the htlc_accepted hook: others will become multi-user in future releases.
• Prevent a case where grossly unbalanced channels could become unusable.
• New config option --large-channels (also known as 'wumbo') which enables opening channels of any size. (Note that your peer must also support large channels.)
• This release includes a keysend plugin, which will enable receiving 'keysend' payments, as first introduced by Lightning Labs. Note that the included keysend plugin is receive only for this release. Nodes which do not want the hassle of spontaneous unrequested payments should add 'disable-plugin=keysend' to their config!
• We'll now announce multiple connection endpoints for a single 'type', e.g. multiple IPv4 addresses.
• Big performance improvement in the pay command (~1s speedup on average).
• c-lightning nodes can now participate in creating larger channels (with the --large-channel config option).
• We now wait until the first payment through a channel before updating the feerate; this should help with some spurious closures at channel open or re-connect that were occurring against older versions of other implementations.
• A new command getsharedsecret for getting the BOLT-compliant shared secret finding for a node and a point.
• Facilities for building rendez vous compatible onions has been added to the onion devtool.
• Plugin options will now respect the type they were given in the manifest.
• Fixes with plugin cleanups and hangs.
• Python2 has been removed as a dependence.

Features

• Ability to create new channels
• Ability to close existing channels
• Completely manage all channel states, including exceptional ones
• Performing path-finding within the network, passively forwarding incoming payments
• Sending outgoing onion-encrypted payments through the network
• Automatic channel management (auto-pilot)
