Wine Chain is a public blockchain for wine, based on blockchain and traceability technology, along with a semi-decentralized system for tracing the origins of wine products. Leveraging the inherent freedom, openness, and fairness of blockchain, it facilitates the free flow of global wine value information, optimizes the wine supply chain to reduce transaction costs, and achieves a high level of alignment between the wine industry and market through intelligent means, creating a dedicated international community. Wine Chain comprises four main application modules: product traceability, blockchain + IoT solutions, cross-chain interoperability, and lightning payments. Its underlying technical framework adheres to multiple specifications and standards set by the Qtum Hyperledger project, with modifications specifically tailored for the wine industrys business scenarios.
