 * **BBS+ Signature**: the scheme has been integrated through the [ZKryptium](https://github.com/Cybersecurity-LINKS/zkryptium) library for secure and privacy-preserving VC management with ZK selective disclosure.
 * **JSON Web Proof Representation**: the [json-proof-token](https://github.com/Cybersecurity-LINKS/json-proof-token) library implements the JSON Web Proof (JWP) specification, enabling verifiable claims with selective disclosure.
