 To resolve DID earth method DID Documents the `QueryIdentifierDocument` operation fetch a response from the ledger. The integrity of the DID documents stored on the ledger is guaranteed by the underlying Cosmos blockchain protocol. DID resolution requests can be sent to the gRPC IID resolver interface for a node by passing the fully-qualified DID.
