Cross-chain identity solutions leverage interoperability protocols like IBC or Polkadot's XCMP to share identity data across blockchains. These protocols enable verifiable credentials to be issued on one chain and validated on another by wrapping them in chain-agnostic formats. Decentralized identifiers (DIDs) provide universal anchors, while zero-knowledge proofs allow selective disclosure of attributes without exposing underlying chain details. Cross-chain oracles facilitate data synchronization between ecosystems.
