A globally unique, cryptographically verifiable identifier that does not depend on a centralized identity authority.
A Decentralized Identifier (DID) is a new type of globally unique identifier designed to enable verifiable, decentralized digital identity. Unlike traditional usernames or email addresses, DIDs are generated and controlled cryptographically by the subject.
Assigned to corporate entities (PT-1), IoT vehicle gateways, and authority auditors, providing self-sovereign cryptographic identity verifiable across all logistics partners.
Format: `did:tt:0x...` resolving to a DID Document containing cryptographic public keys and service endpoints.
Possession of a DID proves cryptographic identity, but does not verify corporate legal standing without an accompanying Verifiable Credential (VC).
