Introducing Event-Driven Properties Management in *-chain

Blockchain technology has improved supply chain management by increasing transparency, traceability and automation. This paper introduces an updated version of *-chain, an automated framework that enables the creation of supply chain management systems from high-level designs through a user-friendly web interface. The proposed improvements integrate events into Ethereum smart contracts to enable asset property notarisation throughout the supply chain, without modifying on-chain states. This approach optimises efficiency and reduces costs while preserving decentralisation and data immutability.
