US Patent 11537592 Metadata management through blockchain technology

Systems, apparatuses, methods, and computer program products are disclosed for providing blockchain-based metadata management. An example method includes receiving an electronic indication of a change in a metadata data structure within a first metadata block stored in a metadata blockchain stored in a blockchain data storage device. The example method may further include determining a set of node devices impacted by the change in the metadata data structure. The example method may further include generating a metadata change consensus notification message. The example method may further comprise transmitting the metadata change consensus notification message to each impacted node device in the set of impacted node devices. Subsequently, the example method may include generating a smart contract in response to receiving a metadata change approval message from each node device impacted by the change in the metadata data structure.
