Hyperledger Fabric and Composer

Hyperledger Fabric

• Hyperledger Fabric is a platform for deploying Blockbain networks. 

• The Ledger, Smart Contract, and consensus between members are maintained by using Fabric Protocols 

• Hyperledger Fabric offers high levels of performance, protection, and transaction privacy. Fabric is the leader in blockchain for business, and can enable modular components to suit various usecases. 

• IBM Blockchain platform is built upon Hyperledger Fabric and, as a result a basic understanding of Fabric's components are architecture is important for developers and decision makers to understand.

Fabric consists of the following components

• A ledger

• Peers

• A Channel

• Chaincode

• Ordering Service

• Certificate Authority

• HyperLedger Fabric Clint SDK

Hyperledger Composer

• Composer is a open source development toolset and framework that accelerates the time it takes to write blockchain applications. instead of developing smart contracts from scratch, Composer provides a convenience layer and business-level abstractions to implement smart contract on Fabric.

• Composer also makes it easier to connect to your business network from web and mobile app.

• Composer helps you to define your business network using a custom modelling language and a small set of primitives, and then deploy the business network a Hyperledger Fabric.

• The business network consists of participants, assets and transactions, access control lists.
