Fujitsu And Accenture Team Up To Launch Hyperledger Cactus

  • The companies said that this project aims to advance cross-industry blockchain technologies and it is hosted by the Linux Foundation
  • Fujitsu Laboratories and Fujitsu Laboratories of America will integrate the ConnectionChain technology with Accenture’s Blockchain Integration Framework

Fujitsu Laboratories Ltd and Fujitsu Laboratories of America Inc (FLA) have collaborated with Accenture for the open source project called project “Hyperledger Cactus” by Hyperledger. The companies said that this project aims to advance cross-industry blockchain technologies and it is hosted by the Linux Foundation. The companies had submitted a proposal to the community for the development of an open source software (OSS) project for secure and reliable integration between multiple blockchains.

Brian Behlendorf, executive director of Hyperledger said, “Hyperledger Cactus has moved quickly through the process of becoming a Hyperledger project thanks to the support and initial code contributions of Accenture and Fujitsu and a compelling use case. There is strong community interest in facilitating the flow of information and transactions across disparate blockchains, and Hyperledger Cactus is tackling that challenge. Now that Hyperledger Cactus is a full Hyperledger project, there will be an even bigger pool of resources and contributors driving this project forward with the aim of delivering market-ready blockchain integration technologies.”

Security technology ConnectionChain

Along with Accenture, Fujitsu Laboratories and FLA will utilise the Fujitsu Laboratories’ proprietary security technology ConnectionChain. They will develop infrastructure software that will enable the development of integrated services in which multiple different blockchains work together. The companies have open-sourced the software for Hyperledger Cactus.

The companies said that the project will develop the foundation for a new architecture that will eliminate differences like the timing of transactions between multiple blockchains, enabling asset transfers and recovery from transaction errors. This project aims to create a modular, extensible system that will enable integration, communication, operations and transactions between different blockchains. The companies will also offer a Software Development Kit(2) as an OSS, It will offer services that integrate multiple blockchains for software developers.

The companies said, “For example, by applying the infrastructure of Hyperledger Cactus in car-sharing services, a new service can be created in which a driver can temporarily use a car in exchange for transferring private coins, while linking a car-sharing service blockchain that manages the rights of car usage, with a blockchain handling private coins. Unlike conventional blockchains, which cannot integrate different blockchains or get excess money back from remitted coins, the Hyperledger Cactus framework automatically links different blockchains. Moreover, the technology can monitor the results of such operations, enabling the rapid development of integrated services that combine multiple blockchains.

No central management

Blockchains are being increasingly used in non-financial areas such as content management and rights management as they are difficult to modify and do not require central management. Nowadays, as real assets are digitized and users directly trade them with each other in various applications that interact with multiple blockchains, a player is needed as a starting point of trust in the interconnection. So, a common platform to protect the transparency and security of such interconnection was required which also had a general mechanism that could connect multiple blockchain foundations.

In November 2017, Fujitsu Laboratories developed a proprietary security technology ConnectionChain to safely interconnect blockchains with varying implementation methods and objectives. The software for exchanging different private coins was made freely available as an OSS

Under the Hyperledger Cactus project, Fujitsu Laboratories and FLA will integrate the ConnectionChain technology with Accenture’s Blockchain Integration Framework. This will be done to develop a platform for interconnecting blockchains and further activate digital transformation.
