A fork of rust-lightning with support for advanced and experimental features such as custom scripts and advanced LSP tooling.

The primary crate, lightning, is runtime-agnostic. Data persistence, chain interactions, and networking can be provided by LDK's sample modules, or you may provide your own custom implementations. More information is available in the About section.

The project implements all of the BOLT specifications, and has been in production use since 2021. As with any Lightning implementation, care and attention to detail is important for safe deployment.

1. lightning The core of the LDK library, implements the Lightning protocol, channel state machine, and on-chain logic. Supports no-std and exposes only relatively low-level interfaces.
2. lightning-background-processor Utilities to perform required background tasks for Rust Lightning.
3. lightning-block-sync Utilities to fetch the chain data from a block source and feed them into Rust Lightning.
4. lightning-invoice Data structures to parse and serialize BOLT #11 Lightning invoices.
5. lightning-net-tokio Implementation of the rust-lightning network stack using the Tokio async runtime. For rust-lightning clients which wish to make direct connections to Lightning P2P nodes, this is a simple alternative to implementing the required network stack, especially for those already using Tokio.
6. lightning-persister Implements utilities to manage rust-lightning channel data persistence and retrieval. Persisting channel data is crucial to avoiding loss of channel funds.
7. lightning-rapid-gossip-sync Client for rapid gossip graph syncing, aimed primarily at mobile clients.

The goal is to provide a fully-featured and incredibly flexible Lightning implementation, allowing users to decide how they wish to use it. With that in mind, everything should be exposed via simple, composable APIs. More information about rust-lightning's flexibility is provided in the About section above.

For security reasons, do not add new dependencies. Really do not add new non-optional/non-test/non-library dependencies. Really really do not add dependencies with dependencies. Do convince Andrew to cut down dependency usage in rust-bitcoin.

rust-lightning refers to the core lightning crate within this repo, whereas LDK encompasses rust-lightning and all of its sample modules and crates (e.g. the lightning-persister crate), language bindings, sample node implementation(s), and other tools built around using rust-lightning for Lightning integration or building a Lightning node.
