This specification describes a Data Integrity Cryptosuite using the BBS Signature Scheme using BLS12-381 elliptic curve based key pairs.

Due to the properties of the BBS Signature Scheme a zero knowledge proof can be derived from the signature, whereby the party generating the proof can elect to selectively disclose statements from the originally signed payload.

We encourage contributions meeting the Contribution Guidelines. While we prefer the creation of issues and Pull Requests in the GitHub repository, discussions also occur on the public-vc-wg mailing list.
