US Patent 11038857 Data messaging service with distributed ledger control

A messaging server receives a network packet that encapsulates a user packet that indicates a source domain and a destination domain. The user packet encapsulates a data message that indicates a code and comprises encrypted data. The messaging server transfers the user packet to a distributed ledger. The distributed ledger executes a distributed ledger transaction with the domains and the code to determine a receiving device. The distributed ledger commits the user packet and device identifiers to distributed ledger memory and transfers the user packet and the receiving device identifier to the messaging server. The messaging server encapsulates the user packet in a network packet for delivery to the receiving device. The user packet encapsulates that data message that indicates the code and comprises the encrypted user data.
