Identity systems enable portability by using decentralized identifiers (DIDs) and verifiable credentials (VCs) compliant with W3C standards. Credentials are issued with cryptographic proofs that any network can verify, regardless of origin. Cross-chain protocols (e.g., IBC) or interoperability layers (e.g., Hyperledger Aries) translate formats between ecosystems. Users control data sharing via selective disclosure, ensuring credentials remain valid and private across networks.
