DID Document
The JSON document a DID resolves to, containing the subject's public keys, authentication methods, and service endpoints. It lets a verifier find the keys needed to check credentials or signatures associated with the DID, per the W3C DID Core specification.
The DID document is the trust anchor for everything else in a decentralized exchange: it names the keys that can authenticate as the subject and the endpoints where the subject can be reached. Key rotation is handled by updating the document rather than reissuing the identifier, which is the practical advantage over a raw public key. Verifiers must resolve it freshly enough to catch rotation and revocation.
