Bitcoin protocol core library

The library implements bitcoin protocol elements which are missed from other existing bitcoin libraries, like rust-bitcoin and [descriptor wallet]. Currently, it includes components necessary for client-side-validation over bitcoin, specifically

• deterministic bitcoin commitments API (LNPBP-14, 6 standards)
• bitcoin-based single-use-seal API (LNPBP-10 and LNPBP-39 standards)

Client-side-validation is a paradigm for distributed computing, based on top of proof-of-publication/commitment medium layer, which may be a bitcoin blockchain or other type of distributed consensus system.

The development of the library is supported by LNP/BP Standards Association.

Usage

To use libraries, you just need latest version of libraries, published to crates.io into [dependencies] section of your project Cargo.toml. Here is the full list of available libraries from this repository:

bp-dbc = "0.5" # Deterministic bitcoin commitments crate
bp-seals = "0.5" # Bitcoin single-use-seals crate
bp-core = "0.5" # Library including both of the previous crates

bp-core crate is an "umbrella" library containing both deterministic bitcoin commitments and bitcoin seals crates inside.

Known applications

The current list of the projects based on the library include:

• RGB: Confidential & scalable smart contracts for Bitcoin & Lightning
• Bitcoin-based decentralized identity proposal uses single-use-seals
