Abstract:

A blockchain system may include nodes, member network entities, and a protocol entity. The nodes together are configured to maintain an immutable record as a blockchain, based on commands provided by the protocol entity. A member may provide a request for a transaction to the protocol entity to perform an operation along with encrypted data. For example, the operation may include a transaction. The protocol entity may invoke a smart contract at one or more nodes to perform the operation on the encrypted data. In response, the node decrypts the encrypted data using a decryption key stored in the node storage equipment to generate cleartext data. The node then performs the operation based on the cleartext data and secures the cleartext data. The immutable record of the blockchain to be updated based on the operation. For example, the secured data and audience permission information may be added to the blockchain.
