Blockchain-based Emergency Supplies Information Sharing System

Blockchain technology is characterized by decentralization, traceability, and resistance to information tampering. To address issues such as untimely information dissemination of emergency supplies and difficulty in tracing materials during emergencies, the paper constructs an emergency supplies information sharing system based on blockchain technology, proposes an information storage model, and uses the Solidity language to design information sharing smart contracts. The results indicate that the constructed emergency supplies information sharing system effectively addresses issues of information opacity and low distribution efficiency of emergency supplies. It is both feasible and broadly applicable. Additionally, the designed smart contract ensures the transparency and security of emergency supplies information sharing, significantly enhancing the transparency and security of emergency supply management.
