Blockchain Beyond Cryptocurrencies: A Real-World Use Case - A Non-Repudiable Supply Chain Tracking System

摘要

Blockchains have recently emerged as an architectural style to overcome the intrinsic trust problem that arises when single central authorities are delegated the role to keep certification information for different parties and actors. By fueling a host of different cryptocurrencies, various forms of blockchains are revolutionizing the finance sector. However, blockchains are rapidly emerging outside of the finance sector, disrupting the business scenarios. This paper presents a novel Supply Chain Tracking system that eliminates fraud and counterfeits from a specific business sector, namely toner cartridge regeneration, where a recent European directive (and subsequent national regulations) has posed stringent limitations.
