2. Key Types

Supported cryptographic key types:

Ed25519   - Signatures (recommended)
X25519    - Key agreement
secp256k1 - Ethereum compatibility

3. Resolution

DID documents resolved cryptographically from the identifier. No network calls required.

{
  "@context": "https://www.w3.org/ns/did/v1",
  "id": "did:key:z6Mk...",
  "verificationMethod": [{
    "id": "did:key:z6Mk...#z6Mk...",
    "type": "Ed25519VerificationKey2020",
    "controller": "did:key:z6Mk...",
    "publicKeyMultibase": "z6Mk..."
  }]
}

4. Agent Profiles

Optional metadata stored off-chain.
Linked via DID document service endpoints.
