ORB

ORB is a decentralized identity project whose core implements the did:orb verifiable data registry method. It is based on a federated, replicable registry architecture where Orb servers propagate DID operations across networks, using witness ledgers, the Sidetree protocol and ActivityPub to issue and verify credentials without a public blockchain as coordination layer. The design lets identity data sync across multiple operators without a consensus chain.

Narratively ORB is positioned as self-sovereign identity and verifiable-credential infrastructure for institutions and developers needing cross-organization identity recognition. Its mechanism distributes DID document writes and resolution across mutually witnessing server clusters for censorship resistance and availability, distinct from single-chain identity schemes and from biometric Orb hardware projects.
