A highly modular and performant Bitcoin Lightning Network library written in Rust, enabling custom Lightning node integration.
Rust-Lightning is a library that implements the Bitcoin Lightning Network protocol in Rust. It provides the core logic for payment channels, routing, and on-chain interactions, enabling developers to build or integrate Lightning nodes without reimplementing the complex protocol details. It solves the problem of needing a secure, flexible, and production-ready Lightning foundation for custom applications.
Developers building Bitcoin Lightning nodes, wallets, or applications that require deep integration with custom chain sync, key management, storage, or networking backends. It's also suitable for those working on related protocols like Discreet Log Contracts (DLCs).
Developers choose Rust-Lightning for its unparalleled modularity and flexibility—it doesn't force specific storage, networking, or runtime choices, allowing seamless integration into existing systems. Its production-ready status, full BOLT compliance, and focus on security via minimal dependencies make it a robust foundation.
A highly modular Bitcoin Lightning library written in Rust. It's rust-lightning, not Rusty's Lightning!
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements all Lightning Network BOLT specifications, ensuring protocol correctness and interoperability with other nodes, as stated in the README's status section.
Decouples core logic from storage, networking, and chain interactions via clean APIs, allowing integration with any backend like cloud storage or custom databases, as highlighted in the About section.
In production use since 2021 with a focus on minimal dependencies and security audits, providing a robust and audited foundation for critical financial applications.
Core crate is runtime-agnostic and supports `no_std`, enabling deployment in embedded environments or with custom async runtimes like Tokio, per the runtime-agnostic design goal.
Requires implementing multiple interfaces for storage, chain sync, and networking, as the README admits it doesn't provide these by default, leading to a complex setup process.
Demands deep understanding of both the Lightning protocol and Rust, making it inaccessible for developers without prior experience in low-level systems or cryptocurrency.
Even with sample crates, integrating custom features involves writing substantial boilerplate code, which is why alternatives like LDK-node exist for easier use.
