The Linux Foundation’s Hyperledger Project is an open source blockchain initiative designed specifically for business, enabling developers to re-invent transactional business processes. One component of the project, Hyperledger Composer, aligns business requirements with technical expertise through a business-centric abstraction. This developer shows you how to use Hyperledger Composer and its business network model, tools, and editors to write, deploy, and test chaincode on LinuxONE.
Blockchain technology is growing fast. According to one article, $1.4 billion was invested in blockchain technologies in 2016 alone. Estimates show that by 2024, the global blockchain market is expected to be worth $20 billion and that for 2017, the average investment in blockchain projects is $1 million.
With so many resources being poured into blockchain technology to drive it forward and create new offerings, it’s hard to know where to begin and how to integrate blockchain with existing business processes. This developer pattern shows you how to start to implement the development/business integration. You’ll learn how to use Hyperledger Composer’s development tools, including Node.js, npm, CLI, and popular editors, to create a development environment for Hyperledger Fabric, a blockchain framework implementation. In the environment setup, you’ll create a small business network running Hyperledger Fabric v1.0.
The environment runs on LinuxONE technology. Yes, it can run on various platforms, but LinuxONE was chosen because of the isolation, availability, scalability and encryption it provides. Running a blockchain network on LinuxONE can produce performance gains while decreasing security risks through cross-memory communication to existing Systems of Record (for example, SCM or ERP) or transactional middleware (such as CICS®, IMS™, DB2®, or batch systems).
You’ll register for guest access to the LinuxONE Community Cloud, run a script that creates your environment, and then interact with Hyperledger Composer and create and deploy a blockchain application. When you complete this pattern, you’ll have opened the door to blockchain development on the mainframe, a valuable combination for any developer to have.
