Blockchain is as significant now as the Internet was 25 years ago. – Thomson Reuters Well, we couldnt quote anything more relevant and self explanatory here. Blockchain is the new Internet, new personal computer, new rocketry, and all that amazed us with their enormous potential few decades ago. Both Blockchain and DLT are a little complex and detail oriented tech phenomena that make people do some intense mental push ups initially. Howbeit, once they start grasping the know how of its unfailing mechanism, they tend to dig deeper and recognise its real life applications. Perhaps, this is the reason why every modern industry today is amenable to the idea of lea.rning and implementing Blockchain in their business model and reap the rewards of efficiency, transparency, and next level security. Blockchain technology isnt just a more efficient way to settle securities. It will fundamentally change market structures, and maybe even the architecture of the Internet itself. – Abigail Johnson Now, if you too are open to the idea of embracing decentralization, all that well be talking next might prove lucrative for you. Here we are just on the cusp of introducing Hyperledger Fabric, an advanced open source framewor.k favoured much to create permissioned Blockchain networ.ks. Whats Hyperledger Fabric? Why it is Different? Hyperledger Fabric is a Blockchain implementation platform geared to support the development of applications or solutions with a modular architecture. It is one of the eight and in fact, the most successful projects hosted by The Linux Foundation. Now, there are multiple Blockchain platforms, but what makes HLF unique is the fact that it underpins a modular architecture to deliver high degrees of coidentiality, flexibility, resiliency, ability to scale. Its extensive and elastic architecture gives it an upper hand over all other Blockchain solutions competing in the market. Moreover, the biggt distinguishing factor is the fact that unlike the open permissionless system that allows unknown entities to participate in the networ.k, Hyperledger Fabric enrolls users via a trusted Membership Service Provider MSP thus creating a closed ecosystem. Then co.nsensus, ledger storage, hosting and costing are more points that reflects the disparity between HLF and alternative Blockchains. Basic Actors in a Hyperledger Fabric Setup The five main defining actors of Fabric setup are listed as Peers Most active elements operating in the HLF setup. These are nodes co.nnected to clients SDK and responsible for hosting smart co.ntracts. Certificate Authority Dispenses digitally signed certificates to different actors to verify ownership in the networ.k. These certificates bind the actor and the actors public key. Orderer Orderer is responsible for ascertaining that all the peers in the networ.k have committed a transaction. Whenever a transaction is proposed or committed by a peer, orderer is notified about the new transaction. Then it forwards and commits this block to all adjacent peers. Channel Wondering what defines channel? Well, members organizations, anchors peers per member, the shared ledger, chaincode applications and the ordering service nodes sums up the channel. Every transaction on the networ.k is executed on a channel. Chaincode Written in Go or Java, Chaincode is a programmable code that is instantiated on a channel. It is the smart co.ntract that runs on the peers and creates transactions. Data Flow in the Hyperledger Fabric The most simplistic version of Data Flow in the HLF networ.k is explained in the image below Heres a typical data flow A transaction proposal is submitted by an application to an endorsing peer Admin peer. The Endorsement policies give a brief of how many and/or what combination of endorsers are required to sign a proposal. The endorser executes the chaincode smart co.ntract to simulate the proposal in the networ.k peer, creating a read/write set. All endorsing peers send the signed proposal responses endorsements back to the application. The application submits the transactions and signatures to the ordering service, which creates a batch, or block, of transactions and delivers them to committing peers. Each time a committing peer receives a transaction batch, it validates that the endorsement policy was met for each transaction. It also checks in the read/write sets to detect any colicting transactions. When both checks pass, the block is committed to the ledger. With this, the state updates for each transaction and are reflected in the state database. Architecture of Hyperledger Fabric Image Source The diagram shows the entire architecture and the hierarchy of components. The Hyperledger Fabric co.nsists of many nodes that communicate with each other. The blockchain runs programs known as Chaincode central element, as t
