This specification describes a Data Integrity Cryptosuite using the BBS+ Signature Algorithm using BLS12-381 elliptic curve based key pairs.
Due to the properties of a BBS+ Signatures 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.
The following is a list of known implementations of this specification
- jsonld-signatures-bbs (Typescript + Rust)
- aries-framework-go (Golang)
- go-bbs (Golang)
- W3C Credentials Community Group Mailing List (Incubation)
- W3C Verifiable Credentials WG Mailing List (Standardization)
- Anyone can open a PR on the repository. Note that for the PR to be merged, the individual must agree to the W3C Patent Policy.
- Once a PR is opened, it will be reviewed by the Editors and other WG Members.
- The W3C CCG is automatically notified of PRs as they are raised and discussed.
