Are you ready to start seamlessly building blockchain apps on Hyperledger® Fabric™ from the Linux Foundation®?

IBM IT Specialist Mohamoud Egal takes you on a tour of Hyperledger Composer and demonstrates how you can easily create and manage your own application using Composer, JavaScript, and API calls.

Hyperledger Composer is an application development framework which simplifies and expedites the creation of Hyperledger® Fabric™ applications. It is a set of APIs, a modeling language, and a programming model you can use to quickly define and deploy business networks and applications that allow participants to send transactions that exchange assets.

The IBM Blockchain, based on open source Hyperledger® Fabric™ technology, is used to store the state of assets in asset registries while the consensus protocol ensures that transactions are validated by concerned organizations in the business network.

The Composer programming model is based on defining and deploying a business network definition, which contains a data model that defines the name and structure of assets, participants, and transactions in the business network. The business network also specifies transaction processor functions (written in ES5 JavaScript) that are automatically run on a Hyperledger® Fabric™ when transactions are submitted by clients.

Composer defines JavaScript APIs to submit transactions and to create, retrieve, update, and delete assets within asset registries.
