Rust bindings to libbitcoinconsensus

crates.io docs.rs CircleCI

This project allows Bitcoin software to be written in Rust while using the same library for script verification that Bitcoin Core uses.

cargo build will automatically check out the Bitcoin Core GitHub repository, configure and build it, and build the bindings statically linked to libbitcoinconsensus and libsecp256k1.

Currently building against the consensus library from Bitcoin Core v0.18.0.
