17. When DID Documents (16), in turn, are serialized to the Verifiable Data Registry (VDR) (replica) (36) and (38) by the Indy Ledger Nodes (35) and (37), they are stored as a series of Indy VDR Transactions. Edge Agents and Cloud Agents call an VDR Node to persist a DID Document to the VDR. DID Documents, specifically, are written to the VDR by the Indy Ledger Nodes using: Indy NYM transactions (50), and Indy ATTRIB transactions.
