Fujitsu Laboratories Ltd., a wholly owned subsidiary of leading Japanese information and communication technology (ICT) company Fujitsu Limited, has announced the development of a technology that speeds up transaction processing for Hyperledger Fabric, one of the Hyperledger blockchain frameworks hosted by The Linux Foundation.

The newly developed technology accelerates transaction processing by making the processing of communications between applications and the blockchain platform more efficient. According to the official release, a trial in which this technology was implemented in Hyperledger Fabric v0.6.1(1), resulted in an increased transaction performance by approximately 2.7 times compared to the previous method.

Fujitsu noted that the number of transactions that can be executed per unit of time is currently limited by communication bottlenecks through the blockchain network. This makes it difficult to apply the technology to online transaction systems, which demand to process large volumes of transactions.

In order to overcome this limitation, Fujitsu Laboratories developed two technologies to improve transaction performance speed by reducing the number of communications between the applications and the blockchain platform. Features of the newly developed technologies include:

• Differential Update State (DUS) Functionality: Fujitsu Laboratories has developed functionality that executes only differential computations on the specified data, in one processing action on the blockchain platform, and functionality that reduces the number of computations directly linked with the number of communications.
• Compound Request (CR) Functionality: Fujitsu Laboratories has developed functionality to aggregate multiple processes to send to the blockchain platform for batch execution. This functionality makes processing on the blockchain platform more efficient by aggregating multiple processes and also reduces the number of communications.

“Fujitsu Laboratories implemented this technology in Hyperledger Fabric v0.6.1 and measured transaction performance on a blockchain platform consisting of four servers. Whereas the previous method could handle 500 transactions per second, Fujitsu Laboratories achieved 1,350 transactions per second using this newly developed technology, an improvement of approximately 2.7 times,” the release said.

Fujitsu said that this newly developed technology would enable the application of the Hyperledger Fabric framework to online transaction systems that demand high performance in excess of 1,000 transactions per second, such as those demanded by financial institutions.

“Fujitsu Laboratories will continue development of technologies to further speed up the blockchain while adapting them to the latest version of Hyperledger Fabric, and will carry out trials with a view to commercial applications of this technology, with plans to commercialize it through Fujitsu Limited during fiscal 2017”, it added.
