Future Enhancements

Planned features aim to increase flexibility, security, and privacy. The items below are not yet implemented; they describe the direction of the Issuer Service.

• Key Rotation and DID Updates: Rotate signing keys without downtime and update hosted did:web documents to publish new verification methods, so that previously issued credentials remain verifiable while new credentials are signed with fresh keys. Today, signing keys are Ed25519 keys managed automatically by the service and are not rotatable through the API.

• Zero-Knowledge Proof (ZKP) Support: Add unlinkable predicate proofs (for example, proving "is over 18" without revealing a date of birth) on top of the selective disclosure already available, further reducing the data a holder must share and limiting correlation across presentations.
