This invention discloses a blockchain-based smart retail system and method, belonging to the field of supply chain management technology. The system includes: a blockchain network module with a hybrid architecture; a digital identity and asset management module; a smart contract cluster, including commodity traceability management contracts, token points management contracts, data rights management contracts, and supply chain finance contracts; and an application interface layer module. The method includes four steps: commodity traceability, points exchange, data rights trading, and supply chain finance. Through blockchain and smart contract technologies, the system deeply integrates commodity flow, information flow, value flow, and capital flow, constructing a decentralized, trustworthy collaborative, and fair value distribution new retail ecosystem. This effectively solves problems such as information opacity, isolated points systems, data monopolies, and financing difficulties for SMEs in the traditional model.

The application discloses a kind of based on blockchain technology's cross-industry alliance right management method and system, belong to blockchain technology field.The method includes: system initialization, rule setting, transaction processing and right exchange.System includes alliance chain network, smart contract layer, application layer and external service interface;Smart contract layer is deployed with general right management contract, transaction and account distribution contract, right exchange contract and right pool management contract.The application realizes the generation of general right and the transfer of right gold synchronization through right and fund anchoring mechanism;Through multilevel automatic account distribution, realize the real-time right distribution of multiple roles in single transaction;Adopt hybrid storage on-chain and off-chain, based on attribute encryption and zero-knowledge proof, realize data privacy protection.The application solves the problems of data silos, high trust cost, right idle and insufficient privacy protection in the prior art, and realizes safe, efficient and trusted cross-industry alliance right management.

Supporting various services related to digital legacy that smoothly substitute the procedures for handling digital legacy without waiting for requests from the bereaved family, and recover and delete digital legacy in accordance with the will of the deceased. 【Solution means】 The system is a digital legacy management system in which a first data terminal 3 operated by the contractor himself / herself communicates with a server device 1 that substitutes the procedures for handling the legacy in accordance with the management contract for the digital legacy requested from the terminal. The server device 1 requests the first data terminal 3 to confirm the survival of the contractor himself / herself as a survival confirmation request. The CPU 1-2 determines the survival status of the contractor based on the response result from the first data terminal 3, and automatically deletes the digital legacy of the deceased registered in the contract servers 2-1 to 2-N when the survival status of the contractor cannot be confirmed.
