Key Series Revocation

A client can revoke any existing key series in a DID with did_revoke operation by specifying the ID of the revoked key series. Similar to did_add, this operation requires another active key series to sign and verify its HTTP request.

A private-public key pair is always required to sign and verify a request. Hence, every DID must always have at least one active key series.

A key series cannot be used to revoke itself.
