Fujitsu Laboratories Ltd. has introduced a technology that speeds up transaction processing for Hyperledger Fabric, one of the Hyperledger blockchain frameworks hosted by the Linux Foundation. In a trial where this technology was implemented in Hyperledger Fabric v0.6.1, it increased the performance by approximately 2.7 times as compared to the earlier method.
With blockchain, groups of nodes based on the number of participants form a network and work together to perform a series of processes from executing transactions to validating the legitimacy of transactions. For this reason, the number of transactions that can be executed per unit of time is limited by communication bottlenecks through the network, as compared to previous centralized systems.
Hence it becomes difficult to apply the technology to things like online transaction systems demanding high performance and the ability to process large volumes of transactions. Fujitsu Laboratories learned that under network conditions where a response time of about 64 milliseconds or less is needed, communications between the applications and the blockchain platform during transaction processing are the primary cause of bottlenecks.

Based on this analysis, Fujitsu came up with the new technology featuring the following:
• Differential Update State (DUS) Functionality
This functionality executes only differential computations on the specified data in one processing action on the blockchain platform. It also reduces the number of computations directly linked with the number of communications.
• Compound Request (CR) Functionality
It not only makes processing on the blockchain platform more efficient by aggregating multiple processes, it also reduces the number of communications.
Fujitsu is the leading Japanese information and communication technology (ICT) company offering a full range of technology products, solutions, and services. Approximately 155,000 Fujitsu people support customers in more than 100 countries.
