 TypeScript reference implementation for the [BBS signature scheme](https://github.com/decentralized-identity/bbs-signature). The goal is to help understand and verify the specification. This is NOT a production-ready implementation; testing is minimal and no effort is made to optimize and protect against specialized attacks (e.g., side-channel resistance).

 Given the rapid evolution of the BBS scheme, there might be inconsistencies between the specification and the code; please open issues or file PRs if you find any!
