WorkerRep: Immutable Reputation System For Crowdsourcing Platform Based on Blockchain
This addresses security and trust issues for users of crowdsourcing platforms, though it appears incremental as it builds on existing blockchain and distributed systems concepts.
The authors tackled the problem of centralized reputation systems in crowdsourcing platforms being vulnerable to attacks and manipulation by proposing a decentralized platform with an immutable reputation mechanism built on Ethereum and IOTA, which eliminates the need for third-party trust and reduces task evaluation costs.
Crowdsourcing is a process wherein an individual or an organisation utilizes the talent pool present over the Internet to accomplish their task. The existing crowdsourcing platforms and their reputation computation are centralised and hence prone to various attacks or malicious manipulation of the data by the central entity. A few distributed crowdsourcing platforms have been proposed but they lack a robust reputation mechanism. So we propose a decentralised crowdsourcing platform having an immutable reputation mechanism to tackle these problems. It is built on top of Ethereum network and does not require the user to trust a third party for a non malicious experience. It also utilizes IOTAs consensus mechanism which reduces the cost for task evaluation significantly.
