What is Hyperledger?
Overview
The Hyperledger Project (HLP) is a platform where experts of different industries (like banking, supply chain, Internet of Things (IoT), etc.) collaborate to build new blockchain frameworks. The Linux Foundation developed this platform in 2015.
Many business enterprises want their transactions to be trustworthy; that is, they want to be sure they are paying for the right thing. Blockchain technology can help such organizations. The main idea behind this platform is to create and maintain an open-source distributed ledger framework and code-base that will help businesses to develop their applications that support blockchain. It further intends to provide enterprises with infrastructure, tools, guidelines, and standards to create a customized
Architecture
There is no specific architecture as Hyperledger is meant to be customizable, but a general architecture consists of the following components:
Consensus layer: It is responsible for ordering the transactions chronologically to form a block.
Smart contract layer: It is responsible for holding the business logic and executing the transaction request from the client after checking its validity based on the provided business logic.
Communication layer: It is responsible for peer-to-peer messages between the nodes participating in the shared ledger instance.
Identity service helps add new identities/entities to the network. In addition, it is responsible for managing changes like drops, adds, and revocations.
Policy service: It manages different policies like consensus, endorsement, and group management policies. It relies on other modules to enforce these policies.
API: It provides an interface for the applications to connect to and perform transactions on the blockchain network.
