WorkerRep: Immutable Reputation System For Crowdsourcing Platform Based\n on Blockchain

Abstract

Crowdsourcing is a process wherein an individual or an organisation utilizes\nthe talent pool present over the Internet to accomplish their task. The\nexisting crowdsourcing platforms and their reputation computation are\ncentralised and hence prone to various attacks or malicious manipulation of the\ndata by the central entity. A few distributed crowdsourcing platforms have been\nproposed but they lack a robust reputation mechanism. So we propose a\ndecentralised crowdsourcing platform having an immutable reputation mechanism\nto tackle these problems. It is built on top of Ethereum network and does not\nrequire the user to trust a third party for a non malicious experience. It also\nutilizes IOTAs consensus mechanism which reduces the cost for task evaluation\nsignificantly.\n
