Application: Transaction management method and transaction management apparatus (Patent ID: US20240078225A1)

The patent filed by Hitachi Ltd. describes a transaction management apparatus in a blockchain system, specifically a queuing server. This server is designed to store transaction history between a client (WEB server) and a distributed ledger server, identify transactions updating the same key, save these transactions in a queue, and transmit them after a specified time period where the key is not updated in the same block. Additionally, the queuing server can prioritize transmitting transactions to a distributed ledger server with lower load based on load monitoring results.

In summary, the patent outlines a method and apparatus for efficient transaction management in a blockchain system. The queuing server holds transaction history, identifies key updates, saves transactions in a queue, and transmits them after a set time period. Furthermore, the system can optimize transaction transmission by selecting a distributed ledger server with lower load. This technology aims to streamline transaction processing and enhance the overall efficiency of blockchain systems.
