  • Patent number: 11985263
    Abstract: An asynchronous and concurrent transaction processing method with high-performance oriented to a permissioned blockchain belongs to the field of blockchain technologies. The method designs two processing schemes for abort transactions, namely, additional submission of unnecessary abort transactions that are serializable and delayed centralized processing of long-conflict-chain transaction aggregation. In order to avoid the instability of system transaction processing performance caused by single point failure, the method designs a multi-node round robin consensus strategy. In addition, an inter-node auxiliary concurrency acceleration scheme is designed, which can improve the transaction performance of the whole of the system only by upgrading some of node devices in the system.

  • Patent number: 11789432
    Abstract: Disclosed is a method for identifying and parsing an industrial control protocol based on an industrial gateway. The industrial gateway captures, through a serial port and a network port, messages sent from a host computer and a lower computer to the industrial gateway, extracts features representing different protocol types and protocol fields from the messages, and identifies and parses the messages based on protocol character features.
