Privacy-enhancing decentralised reputation systems: a future of work perspective

Global labour markets face significant disruption from the rapid advance of artificial intelligence (AI) and automation. Digital or gig economy workers, like freelancers and online independent contractors, are more exposed to the disruptive impacts of technological changes due to their flexible working conditions, which often come with flexible contracts, less robust legal agreements and other unstable working conditions. This study explores how gig economy workers benefit from alternative privacy-enhancing decentralised reputation systems and technologies that enable them to manage information like education, certifications, credentials, and professional experience, both by collecting and sharing information with employers. We propose a blockchain framework comprising three components: (1) Self-sovereign identity (SSI) enabling cryptographically secured, portable control over credentials via decentralised storage; (2) Immutable reputation registries leveraging consensus mechanisms to secure tamper-proof work histories; and (3) Privacy-preserving signalling using zero-knowledge proofs (ZKPs) to let workers selectively disclose reputation metrics without revealing sensitive details. We combine Signalling Theory (ST) and the Unified Theory of Acceptance and Use of Technology (UTAUT) to empirically assess real workers’ intentions to use this type of decentralised reputation system. Our framework enhances transparency, worker autonomy, and privacy in the digital economy.
