Groestlcoin Development & Technical Discussion / GRS RPC Explorer signet 3.4.0 ...
Last post by jackielove4u - September 22, 2023, 09:12:35 PM

GRS RPC Explorer Signet: Simple, database-free Groestlcoin signet blockchain explorer via RPC to Groestlcoin Core.

GRS RPC Explorer signet is a simple, self-hosted explorer for the Groestlcoin signet blockchain, driven by RPC calls to your own Groestlcoin signet node. It is easy to run and can be connected to other tools (like ElectrumX) to achieve a full-featured explorer.
Whatever reasons one may have for running a full node (trustlessness, technical curiosity, supporting the network, etc) it's helpful to appreciate the "fullness" of your node. With this explorer, you can explore not just the blockchain database, but also explore the functional capabilities of your own node.

Changelog 3.4.0
• Breaking changes to the API
• Minor fixes for running against Groestlcoin Core v23
• Block Analysis: include top "days destroyed" transactions
• URL change: /mining-template -> /next-block (redirect is included for compatibility)
• On Extended PubKey pages, include balance data for various address (if Electrum-GRS server is configured)
• Several new API actions/changes
• New /holidays, a curated list of Groestlcoin 'Holidays'
• Support for different view options on /fun
• On /difficulty-history, make delta graph honor timespan filtering
• Proper use of production-ready MemoryStore for session data
• Support for serving static assets via a configurable CDN
• Misc fixes for erroneous data display on non-mainnet nodes
• Switch from fontawesome to bootstrap-icons v1.8.0
• Refreshed "Dark" theme with blues toned down (legacy dark theme still available)
• UI/UX tweaks
• Misc minor fixes
• Updated dependencies

Features
• Network Summary dashboard
• View details of blocks, transactions, and addresses
• Analysis tools for viewing stats on blocks, transactions, and miner activity
• See raw JSON content from groestlcoind used to generate most pages
• Search by transaction ID, block hash/height, and address
• Optional transaction history for addresses by querying from ElectrumX
• Mempool summary, with fee, size, and age breakdowns
• RPC command browser and terminal

Groestlcoin Development & Technical Discussion / Core lightning 23.08.1 release...
Last post by jackielove4u - September 22, 2023, 09:09:41 PM
Core lightning: A specification compliant Lightning Network implementation in C

Core lightning is a lightweight, highly customizable and standard compliant implementation of the Lightning Network protocol.
Core lightning only works on Linux and Mac OS, and requires a locally (or remotely) running groestlcoind (version 22.0 or above) that is fully caught up with the network you're testing on.

Changelog 23.08.1
• Several pay plugin improvements for better payment reliability.
• New setconfig command to change config lines dynamically without node restart: limited now, but more coming in future.
• BIP-93 seed backup support
• Per-channel ignorefeelimits setting for getting fee disagreements unstuck.
• Taproot address support: now the default for change addresses.
• Preemptive failure of incoming HTLCs if the outgoing is stuck due to high fees, to avoid channel loss.
• Dual-funding has been tweaked to the latest spec, but it's still experimental.
• The new experimental-splicing option implements the new splicing draft to move funds in and out of live channels.
• A new wait command supports invoices, along with listinvoices allowing ordering and pagination (with more commands to come!)
• pay supports self-payment: you can pay your own invoices.
• pay int a bolt11 with a description hash without providing a description has been temporarily undeprecated (but descriptions now work properly with \ in them now!).
• Experimental builds are no longer required: all experimental features are now explicit runtime options.
• User-defined tracepoints have been added to the a few paths, to help with tracing bottlenecks in production systems.

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).

• 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.
