Boomerang: Blockchain-based Freelance Paradigm on Hyperledger

Abstract

There has been a great focus on services across the Internet. Freelancing is one such service that is thought to be in the middle of a dramatic change. Here, the online freelancing platforms have created global opportunities for people to outsource their works, and seek employment slots, like a job. Online freelancing platforms have transformed how, when, and where the work is to be performed. However, these platforms also carry risks. These platforms lack credibility, security, and flexibility d ue to centralized nature. Designing n ew approach, that overcomes these issues, is very important for growth of freelancing. This paper proposes Boomerang, a decentralized freelance administration paradigm on Hyperledger Fabric. Hyperledger Fabric is a distributed operating system for permissioned blockchains. The Boomerang integrates blockchain-based distributed ledger, consensus protocol, and a fine-grained access control. The design includes demonstration of Boomerang and a detailed description of Boomerang architecture. The prototype implementation, based on the Boomerang architecture, is detailed next. The implementation of database and application logic are illustrated for better understanding. In addition, the tools chosen and assumptions made in prototype development are mentioned. This research would help the coming and existing startups to secure grow fast with requisite security.
