SEOHFB: A Secure Environment for Organization based on Hyperledger Fabric Blockchain

Blockchain and hyperledger are decentralized approaches used for maintaining security, secrecy, and integrity of organization based business transactions. In our study we have built a permissioned blockchain using HyperLedger Fabric framework that able to handle data storage and secure intra-and inter-organizational communication. The key reason for which we have chosen HyperLedger Fabric framework is that, it uses RAFT consensus algorithm that provides permissioned blockchain network by creating a channel that was unavailable to the public blockchain network. We have made a smart contract for the permissioned blockchain by developing and writing the chaincode. We have used Fabric-CA server to generate crypto material. Then we have set up the network configuration, organizations, ordered peers, endorsing peers, anchor peers and developed client application for Hyperledger Fabric. We have integrated the web-front with fabric using WEB-API.
