C-lightning

Core lightning: A specification compliant Lightning Network implementation in C.

Core lightning is a lighweight, 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 2.16.0 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).
