DID with Blockchain
Decentralized identifier - Wikiwand
Decentralized Identifiers (DIDs) v1.0
- Identifies a person, organization, or device.
- Has a resolvable DID Document describing public keys, service endpoints, etc.
- Is controlled using cryptographic keys.
- Works across DID methods (did:ion, did:key, did:web, did:ethr, etc.)
| DID Method | Where the key is stored |
|---|---|
| did:ion | Bitcoin + Sidetree network |
| did:web | HTTPS web server hosting a JSON file |
| did:key | In-place |
| did:ethr | Ethereum |
| did:sov | Hyperledger Indy ledger |
