Decentralized identity (DID) systems can comply with Anti-Money Laundering (AML) laws by integrating verifiable credentials (VCs) for identity verification. Users submit government-issued VCs (e.g., passports) to regulated entities, which validate them via blockchain without storing raw data. Smart contracts can enforce transaction limits or flag suspicious activity, while zero-knowledge proofs enable privacy-preserving compliance checks. Auditable logs on-chain ensure transparency for regulators, balancing AML requirements with user data sovereignty.

Identity federation capabilities with existing systems: Identity federation allows different systems to share and recognize user identities. It enables single sign-on across multiple platforms. Existing systems can integrate through standards like SAML or OAuth. This allows users to use one set of credentials to access various services, enhancing convenience and reducing the need for multiple logins.

Identity networks use offline-first designs, allowing local credential verification during partitions via cached data or peer-to-peer sync. Once connectivity resumes, nodes reconcile conflicts using consensus mechanisms (e.g., CRDTs for eventual consistency). Hybrid systems combine on-chain anchors (for global state) with off-chain channels (for local operations). Partition-tolerant protocols like Hashgraph prioritize availability, ensuring basic identity functions persist during outages.
