RustBitcoin

RustBitcoin is a software library written in Rust that provides core primitives for working with the Bitcoin protocol. The project aims to offer safe, ergonomic access to Bitcoin data structures and rules, enabling developers to build wallets, tools, or lightweight nodes with a focus on correctness and performance.

Key features include representations of fundamental Bitcoin objects (transactions, blocks, scripts, addresses, keys), parsing and serialization of standard formats, and utilities for signing and verifying signatures. The library includes support for cryptographic primitives used by Bitcoin, such as elliptic curve operations on secp256k1 and hash functions, as well as utilities for working with transaction signatures and script evaluation. It is designed to be modular, with separate crates or modules for primitives, consensus rules, serialization, and networking helpers.

Design goals emphasize safety and zero-cost abstractions typical of Rust, with a focus on predictable performance and explicit error handling. The project aims to be interoperable with other Bitcoin implementations, providing interoperable data types and wire formats while enabling independent testing with comprehensive test vectors.

Usage and reception: rustbitcoin is used by wallet developers and tooling projects that require a pure Rust implementation of Bitcoin primitives. It is maintained by an open-source community and follows common Rust ecosystem practices, including versioned releases, documentation, and automated tests.
