US Patent 11368288 Apparatus and method of lightweight communication protocols between multiple blockchains

A method for inter-blockchain communication, comprising: receiving from a sender node in a sender blockchain a data message for transmission to a receiver node in a receiver blockchain; encrypt and encapsulate by an encryption module the data message into an event, wherein the event comprising an exposed header containing information for routing the event through the blockchains and identifying the sender and the receiver nodes; broadcasting the event to a communication bridge comprising multiple bridge nodes; transferring the event through the bridge nodes to an event exchange module of the receiver blockchain; validating the event by a validation module; decrypting and decapsulating the validated event by a decryption module into a decrypted data message; and recording the decrypted data message into the receiver blockchain ledger for reading by the receiver node. The multiple bridge nodes ensure redundancy for the reliable delivery of events in the inter-blockchain communication.
