Blockchain: Hyperledger Composer for Building a Network

• Programming experience
• Basic understanding of blockchains
• Experience with Linux

Audience

• Developers

Hyperledger Composer is a set of collaboration tools for building blockchain business networks. Composer is built with JavaScript and leverages node.js, npm, CLI and popular editors.

In this instructor-led, live training, participants will learn how to build Blockchain business network and demo application using Composer.

By the end of this training, participants will be able to:

• Simplify the creation of smart contracts and blockchain applications.
• Test devops processes by developing in a protected, risk-free environment before deploying.
• Use Composer's purpose-built modeling language together with JavaScript to script transactions.
• Implement a development process that aligns business requirements with development.
• Develop production-ready browser-based blockchain applications in hours instead of weeks.
• Integrate a blockchain network with existing systems.

Format of the Course

• Interactive lecture and discussion.
• Lots of exercises and practice.
• Hands-on implementation in a live-lab environment.
