How does a blockchain work in hyperledger framework

Question

How does a Blockchain work in Hyperledger composer and fabric?  Also, I know that are no Miners in Hyperledger, then how does it work without mining in a Blockchain? Also, how do Smart  Contracts operate on a Hyperledger platform?

Answer 1

Hyperledger Composer simplifies application development on top of the Hyperledger Fabric Blockchain infrastructure.

Hyperledger is a permissioned blockchain. Mining is primarily the domain of public Blockchains, not Permissioned Blockchains.

The javacript transaction processors and business logic are a constituent part of the Composer business network (ie smart contract) that is deployed to the Blockchain network.

I would suggest you to read the following documents for a better understanding:
