Network System Design using Hyperledger Fabric: Permissioned Blockchain Framework

The network system is a series of clients connected and other peripheral devices. Based on their architecture they can be broadly classified into the client-server or peer-to-peer network. Database system for these networks is further classified into centralized and distributed database systems. The networks that we used, currently depend upon centralized database system. Data integrity is high in this type of system. However, recovery of lost data is complicated, sometimes impossible due to no redundancy. These drawbacks of the centralized database system can be overcome by designing a network using blockchain technologies. Blockchain is a type of distributive database system. In this system, data is spread among all clients, and there is no central server controlling the flow of data. Use of smart contracts, proof of work and encryption among nodes make the flow of data more secure and fast. To make this type of system, we are using hyperledger fabric and composer for designing our network system. Hyperledger fabric is an open source blockchain framework which helps to develop a network system. We are defining a fictitious airline company for which we are creating a network API to handle their business to business (B2B) network system. The necessary foundation is to leverage the hyperledger fabric for the formation of a business network that would enable efficient B2B collaboration leading to a better experience.
