Imagine if you invited 10 friends to a potluck, but some people measured ingredients in 'cups', some in 'grams', and some in 'handfuls'. The recipes would be a disaster! [Standardization](/en/terms/standardization) is like handing everyone the same measuring kit and saying 'everyone must use Liters and Kilograms'. Now, all the recipes work together perfectly. That's what it does for computer data.

🤓 Expert Deep Dive

[Decentralized Identity Management](/en/terms/decentralized-identity-management) (DIDM) is an architecture for Self-Sovereign Identity (SSI) that utilizes cryptographic methods and distributed systems. Its core components are:

Decentralized Identifiers (DIDs): Globally unique, resolvable, and cryptographically verifiable identifiers that individuals or entities generate and control, independent of central registries. A DID document, linked to a DID, contains cryptographic keys and service endpoints.
Verifiable Credentials (VCs): Digital, tamper-evident documents containing claims about a holder, signed by an issuer. Standards like JSON-LD are often used. VCs include the holder's DID, claims, and expiration. Holders present VCs to verifiers for validation.
DID Resolution: The process of retrieving a DID document for a given DID, typically via a distributed ledger or network.
Wallets: User-controlled applications that store DIDs, VCs, manage keys, and facilitate credential operations.
* Blockchain/DLT: Often used to anchor DID registrations, manage DID lifecycles, and provide trust for cryptographic operations, ensuring data immutability and availability.

Typical workflow:
1. DID Creation: User generates a DID and associated keys.
2. DID Registration: DID is registered on a DLT or ledger for resolution.
3. Credential Issuance: An issuer creates and signs a VC with claims, delivering it to the user's wallet.
4. Credential Presentation: User presents a VC (or selective disclosure) from their wallet.
5. Verification: Verifier checks the VC's signature, issuer's DID, and claims against issuer data.
