A blockchain is best understood in the model of state-machine replication [8], where a service maintains some state and clients invoke operations that transform the state and generate outputs. A blockchain emulates a “trusted” computing service through a distributed protocol, run by nodes connected over the Internet. The service represents or creates an asset, in which all nodes Designed as a modular and extensible general-purpose permissioned block- chain, Fabric is the first blockchain system to support the exe- cution of distributed applications written in standard programming languages, in a way that allows them to be executed consistently across many nodes, giving impression of execution on a single globally-distributed blockchain computer. Hyperledger Fabric is a permissioned blockchain framework, with a modular architecture (plug-and-play).

Hyperledger Fabric is a permissioned blockchain framework, with a modular architecture (plug-and-play). It leverages container technology to host smart contract (Chaincode) which contains application logic. Before going to each component in detail let us see a high-level transaction flow and basic components involved. This video will talk through the concepts needed to understand a Hyperledger Fabric solution (first 23 minutes) and then go into the smart contract and clien Hyperledger Fabric CA¶ Hyperledger Fabric CA is the default Certificate Authority component, which issues PKI-based certificates to network member organizations and their users. The CA issues one root certificate (rootCert) to each member and one enrollment certificate (ECert) to each authorized user. Type: Distributed ledger software. Hyperledger Fabric is intended as a foundation for developing applications or solutions with a modular architecture.

For test environments, SoftHSM can be used to satisfy this requirement. The Hyperledger Fabric client SDK provides a structured environment of libraries for developers to write and test chaincode applications.

First and foremost, we get the benefit of scalability. We can grow to match the demand of our network. Azure Blockchain Service supports Ethereum, Quorum Ledger, Corda, and Hyperledger Fabric. As a business, you do not have to manage the ledger. Also, there is no cost associated with the ledger itself. However, you need to pay for the app development and its cost when it runs on the Blockchain.
