The Food Coin Bag (Health Wallet) provides a platform for on-chain storage of all information, offering query and verification services. The Health Wallet boasts low-latency and high-concurrency core technologies in its matching trading system. The most significant value of the Health Wallet lies in its ability to authentically verify content. However, traditional industries face issues such as ease of loss, damage, modification, difficulty in querying, and verifying authenticity. The decentralized, distributed storage, immutability, and transparency of blockchain technology provide strong technical support for the preservation and notarization of food health. Blockchain technology has absolute advantages, extensive application scenarios, and immense value in the field of food health. The Health Wallet platform employs an intuitive front-end interface to create new block-based digital certificates for each member. All personal information is recorded on the blockchain in the form of individual ledgers, generating unique blockchain hashes as identification numbers for each member.
