A digital twin is a virtual replica of a physical object, system, or person, used for simulation or monitoring. Decentralized identity (DID) enhances digital twins by linking them to verifiable credentials (e.g., maintenance logs, ownership proofs). For example, a factory machine’s digital twin could use a DID to authenticate service records or track parts. Individuals’ digital twins (e.g., health avatars) might use DIDs to control data sharing with healthcare providers, ensuring privacy while enabling personalized insights.

Finality depends on the blockchain: Proof-of-Stake (PoS) chains (e.g., Ethereum 2.0) achieve sub-second to 6-second finality, while Proof-of-Work (PoW) (e.g., Bitcoin) may take 10+ minutes. Layer-2 solutions (e.g., Rollups) reduce finality to seconds. Private blockchains (e.g., Hyperledger) offer near-instant finality for enterprise use cases. Users receive confirmation once blocks are irreversibly added.
