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 23.11
• Wumbology for all! The configuration option large-channels is now set by default.
• The dual-funding process stores the state when sending commitment_signed now. This allows to continue the funding process after a temporary connection loss.
• A new flag --commit-fee-offset allows to set an offset that can potentially reduce disagreements on feerate updates.
• Plugins can now allow even unknown messages by registration and also are allowed sending them.
• Some stability improvements and bugfixes regarding splices.
• A whole lot of cleanups to stay on track with small specification changes. This adds additional stability and reduces disconnects.
• The check command just got more powerful. Instead of only checking the parameters of a command, it will do all checks up to the point where something in the system would need to be altered now.
• Control all the runes! Runes got an additional restriction field per for even more powerful access control. This also comes with a new field last_used for the showrunes command.
• Users can now verify the validity of their existing emergency backups using the decode command.
• When the new config option invoices-onchain-fallback is set, Core-Lightning automatically adds a taproot fallback address to all invoices produced by invoice. This allows for onchain payments as a fallback mechanism.

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).

Last post by jackielove4u - December 22, 2023, 08:48:02 PM

A new major Groestlcoin Core version 26.0 is now available for download, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.


v26.0 is now the official release version of Groestlcoin Core. It is recommended to upgrade to this version as soon as possible.

What's new in version v26.0?
This is a major release of Groestlcoin Core, featuring the technical equivalent of Bitcoin Core v26.0 but with Groestlcoin specific patches.


Changelog 26.0:
https://github.com/Groestlcoin/groestlcoin/blob/26.0.0/doc/release-notes.md

Important:
• There is no warranty and no party shall be made liable to you for damages. If you lose coins due to this app, no compensation will be given. Use this app solely at your own risk.
• Encrypt your wallet. This can be done by clicking the settings menu from inside the wallet. Make sure your password is secure and do not forget it.
• Make a copy your wallet.dat file as a backup and move it to a secure location:
Location Windows: Navigate to C:\Users\Username\AppData\Roaming\groestlcoin\wallet.dat (or open windows explorer and enter %appdata%\Groestlcoin\wallet.dat)
Location Mac: Finder -> Go {Hold Option] -> Library -> groestlcoin -> wallet.dat (~/Library/Application Support/groestlcoin/wallet.dat)

WARNING:
While this branch has been extensively tested to be compatible with the existing Groestlcoin v2.11.0, v2.13.3, v2.16.0, v2.16.3, v2.17.2, v2.18.2, v2.19.1, v2.21.0, v2.21.1, v22.0.0, v23.0.0, v24.0.1 and v25.0.0 network there is the possibility that we missed something. ALWAYS BACKUP YOUR GROESTLCOIN WALLET BEFORE UPGRADING.


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. Users running macOS Catalina need to "right-click" and then choose "Open" to open the Groestlcoin Core .dmg.

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
