• 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.
• Open Source - GRS Bluewallet is built on a public repo, up-to-date and available on the Groestlcoin GitHub. This means that any user can build it and run it on his own, without any custodial dependencies. Verify the code and contribute to the wallet development. GRS BlueWallet is made with ReactNative and Distributed under a MIT licensed.
• Watch-only wallets - Watch-only wallets allows you to keep an eye on your cold storage without touching your private key. Easily import your address or xpub and watch it from your app without ever touching it.
• Lightning Wallets - Wallets with support for the Lightning Network Protocol. Unfairly cheap and fast transactions. You can send, receive and refill your wallets.
• 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 Spark Lightning Wallet Android: A minimalistic wallet GUI for c-lightning through Android


Groestlcoin Spark is currently oriented for technically advanced users and is not an all-in-one package, but rather a "remote control" interface for a c-lightning node that has to be managed separately.
Groestlcoin Sparks supports sending and receiving payments, viewing history, and managing channels.
Groestlcoin Spark is a purely off-chain wallet, with no on-chain payments. This allows Groestlcoin Spark to fully realize the awesome UX enabled by lightning.
Groestlcoin Spark has a responsive UI suitable for mobile, tablet and desktop devices, but is best optimized for use on mobile

Changelog 0.3.1:
• BOLT12: Send payments using BOLT12 offers (including support for any amounts, quantities, fiat denomination and sending a payer_note to the payee). Requires c-lightning v0.10.1+ with experimental-offers enabled.
• BOLT12: Create reusable BOLT12 offers to receive multiple payments (basic support only). Requires c-lightning v0.10.1+ with experimental-offers enabled.
• BOLT12: Pull payments using BOLT12 withdrawal offers (send_invoice=true). Requires c-lightning v0.10.1+ with experimental-offers enabled.
• UI: Non-blocking payments with paystatus tracking
• Payments are now sent in the background without blocking the UI, with pending/failed payments shown in the homepage payment history.
• UI: Improve the main screen initial loading times
• Pay/Request can now be used immediately, without waiting for the wallet's data to load first.
• UI: Always display payment amounts in USD terms too
• UI: Improved error reporting and display
• Update clightning-client to v0.1.4
• Use newaddr all to avoid creating new addresses when switching types
• This raises the minimally supported c-lightning version to v0.7.1.
• Reproducibility: Due to changes in third-party dependencies, the Android apk build and the Windows portable runner are no longer reproducible, while the Linux AppImage now is.
• Cordova: Target Android SDK version 30

Features:
• Pay and Request are pretty intuitive and don't require much explaining. Try them!
• Display unit: Click the balance on the top-right or the unit in the "request payment" page to toggle the currency display unit. The available options are gro, groestls, milli, grs and usd.
• Theme switcher: Click the theme name on the bottom-right to change themes (you can choose between 16 bootswatch themes).
• Payment details: Click on payments in the list to display more details. (note that the fee shown includes c-lightning's overpayment randomization)
• Expert mode: Click the version number on the bottom-left to toggle expert mode. This will add two new menu items, "Logs" and "RPC Console", and display yaml dumps with additional information throughout the app.
• Node address: Click the node id on the footer to open the node info page which displays your node address (as text and QR).
• Channel management: Click the "Channels" button inside the node info page to show and manage channels.

Groestlcoin Development & Technical Discussion / C-lightning 0.10.2 released
Last post by jackielove4u - December 22, 2021, 08:29:44 PM

C-lightning: A specification compliant Lightning Network implementation in C


C-lightning is a lightweight, highly customizable and standard compliant implementation of the Lightning Network protocol.
C-lightning only works on Linux and Mac OS, and requires a locally (or remotely) running groestlcoind (version 2.16.0 or above) that is fully caught up with the network you're testing on.

Changelog 0.10.2
• Payments can now be retried without affecting the status of prior attempts.
• The route selection will now use the log-propability-based channel selection to increase success rate and reduce time to completion.
• close now reports the feeranges each side enforced, which allows users to determine which side caused a high or low feerate.
• Removal of old HTLC information and vacuuming shrinks large lightningd.sqlite3 by a factor of 2-3.
• setchannelfee now has a grace period during which both old and new fee policies are considered. This prevents a fee update from making the channel unusable until the update propagated.
• We now perform quick-close if the peer supports it.
• We send regular pings to detect dead connections (particularly for Tor).
• Errors returning a channel_update no longer return an outdated one.
• Anchor output mutual close allow a fee higher than the final commitment transaction.
• Plugins now are notified about an upcoming shutdown, allowing them to store data and clean up before exiting.
• The datastore API (datastore, deldatastore, and listdatastore) exposes a simple key-value store, allowing plugin authors to store data in the c-lightning database.
• ping now only works if we have a channel with the peer.
• Relaxed the sqlite3 version match requirements to be at least a minimum version and a major version match

Features
• Creating channels.
• Closing channels.
• Completely managing all channel states (including the exceptional ones!).
• Performing path finding within the network, passively forwarding incoming payments.
• Sending outgoing onion-encrypted payments through the network.
• Automatic channel management (autopilot).

Groestlcoin Development & Technical Discussion / VerifySignature released
Last post by jackielove4u - September 22, 2021, 08:38:19 PM

Groestlcoin VerifySignature: This implementation can accept get parameters, so it is linkable externally, and users could easily copy-paste one link to their counterparties to verify. This should be useful for people who do OTC and regularly do proof-of-funds before the transaction.


This tool makes it easier for users to verify signatures online/offline.

Features
• open source
• compiles into static html files so it can run completely offline

Live version available at https://verify.groestlcoin.org/VerifySignature  But it is recommended to download Groestlcoin VerifySignature offline and run it on your pc. Open index.html to get started.

Download Groestlcoin VerifySignature here: https://github.com/Groestlcoin/VerifySignature/archive/refs/heads/master.zip
