WorkerRep: Immutable Reputation System For Crowdsourcing Platform Based on Blockchain

TL;DR

This paper introduces WorkerRep, a decentralized reputation system for crowdsourcing platforms built on blockchain technology, enhancing security and reducing evaluation costs without relying on a central authority.

Contribution

It presents a novel immutable reputation mechanism integrated with Ethereum and IOTA consensus, addressing centralization and manipulation issues in existing platforms.

Findings

Decentralized reputation system improves security against malicious attacks.

Utilizes Ethereum and IOTA to reduce evaluation costs.

Provides a trustless environment for crowdsourcing tasks.

Abstract

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.
