The Linux Foundation’s Hyperledger Composer: Driving faster blockchain value

Share this post:

Dan is feeling particularly elated and it’s all thanks to The Linux Foundation’s Hyperledger Composer. This is his third blockchain project as scrum master and it’s always a thrill to deliver the end of project demonstration but this one has been special! It’s the first project Dan has delivered using Hyperledger Composer and he’s amazed at how quickly his team was able to show the true value of blockchain to his customer stakeholders.

Dan recalls how blockchain is a trusted, distributed ledger with business processes shared across a business network. Transactions are agreed to by the network participants and blockchain provides total clarity of who’s done what when, and who owns it. Because blockchain provides one view of truth that is resilient to fraud and cyberattacks, it can be a powerful solution for resolving and even preventing disputes among participants in a business network.

Dan was introduced to Hyperledger Composer at a conference a few weeks before the start of the most recent project. For his first two blockchain projects, his development team built the customer solution in another, less common programming language. This meant the team members always needed a few weeks of hands-on education before they could start the development, and it usually led to frustration. They also needed time to get to grips with the fundamentals of blockchain — particularly network participants, assets and transactions — so they could authentically implement the customer use case.

At the conference, Dan learned that Hyperledger Composer aims to accelerate time to value, allowing customers to focus on building their blockchain awareness and deferring business case discussions to the appropriate time in the agile process. As a founding member of the Hyperledger Project, IBM promoted the use of Hyperledger Fabric as a technical foundation for customer projects.

Simplicity, speed and value for blockchain developers

When Dan returned from the conference, he got his team to check out Hyperledger Composer in more detail. They found that the set of open-source development tools running on top of Hyperledger Fabric was designed for quick solution creation through a business-centric vocabulary. It allows developers to start at the business level, modelling network assets, participants and transactions. Applications can use standard interfaces to invoke transactions that create, delete and update assets, and then transfer them between network participants. Hyperledger Composer also makes it easy to integrate the new blockchain solution with existing business systems of record, again accelerating time to value. Dan was impressed, and sponsored the usage of Fabric Composer for his latest customer project.

The use of Hyperledger Composer allows Dan’s team to have a focused conversation with the customer’s business sponsors to quickly define:

    • The business network and its participants
    • Assets and transactions plus their relationship with the business network participants
    • Rules for sharing and privacy across the business network, to control who can see what
    • The shared business processes, or smart contracts embedding rules for asset transfer

By allowing Dan’s team members to work at a level that makes sense to the business user, Hyperledger Composer shortened the time between the design thinking process and creating a working solution. This allows his customers to demonstrate the true value of a new blockchain solution to key internal and external stakeholders. They found that this could also speed up the blockchain business network formation and allow organizations to realize the full transformational value of their new solution as soon as possible.

Dan is delighted at how Hyperledger Composer has accelerated the time to value on his customer project and is looking forward to using it on future projects.
