A Soulbound Token-based Reputation System in Sustainable Supply Chains

Abstract

This paper aims to provide novel insights in the use of recent advances about non-fungible and Soulbound tokens, as they are a growing reality in the context of the DLT framework. In particular, this work discusses how these technological provisions can enable a renovated and strengthened role of the Internet of Everything concept in the complex processes of the Industry 5.0, where the social, societal, and technical dimensions merge into an irreducible applicative context. The potentialities of the approach are expressed by means of a simple but meaningful example on an industrial case study concerning the food supply chain.
