  • Patent number: 12212697
    Abstract: In a blockchain system, a user device obtains an address of a smart contract according to a transaction hash, and generates a private data hash according to business data. The user device then generates a transaction based on the private data hash and the address of the smart contract, and submits the transaction to the blockchain system to store the private data hash into the smart contract, such that confidential information of a business deal in the real world is secured. An authentication device generates a private data hash according to business data, obtains an address of a smart contract in the blockchain system according to a transaction hash, and accesses the smart contract via the address to determine whether the private data hash is stored in the smart contract. The authentication device approves the business data when the smart contract includes the private data hash.

  • Publication number: 20250028669
    Abstract: An asynchronous bridge with command prefetching, including a command prefetcher as well as a command receiver. The command receiver receives a first command from a first-clock computing device. The first command is issued to operate a second-clock computing device. The command prefetcher prefetches a second command from the first-clock computing device before the first-clock computing device receives notice of execution completion of the first command. In this manner, when the command receiver receives the second command (that the first-clock computing device formally issues to operate the second-clock computing device), the second-clock computing device already operates in response to the prefetched second command.
