# Decentralized Identity
**Concept class:** Identity architecture
## Definition
**Decentralized identity** describes systems in which identifiers, credentials, keys, and disclosure decisions are not controlled exclusively by one central identity provider. Implementations vary: control claims, privacy guarantees, revocation, recovery, interoperability, and legal recognition must be evaluated separately rather than inferred from the label.
## Relationships
- **ION implementation claim:** [[wiki/Ice Open Network|Ice Open Network]] describes ION ID as a self-sovereign identity service with selective disclosure and zero-knowledge mechanisms.
- **technical routes:** verifiable credentials, decentralized identifiers, cryptographic keys, credential issuers, holders, and verifiers.
- **risk routes:** key loss, recovery authority, metadata leakage, governance capture, and unverifiable vendor claims.
- **disambiguation route:** [[wiki/ICE|ICE disambiguation]].
