Decentralized Identifier (DID)

Networking

Decentralized Public Key Self‑Sovereign Identity (SSI) Digital Identity

Identifier resolvable to a document containing public keys and service endpoints, controlled via cryptographic proofs.

Definition

A DID is an identifier that resolves to a DID document listing public keys and service endpoints. Control is typically proven via cryptographic keys, not a central registry account.

In plain English Identifier resolvable to a document containing public keys and service endpoints, controlled via cryptographic proofs.

Why this matters

Why it matters: DIDs can enable portable identity, but privacy depends on preventing linkability and over-sharing.

Example

Example: Use pairwise DIDs per relationship to reduce correlation across services.
