Digital asset recording and querying method for improving transparency of supply chain

Abstract

The invention provides a digital asset recording and querying method for improving the transparency of a supply chain, and the method comprises the steps: achieving the multi-party participation and data sharing of the supply chain through building a block chain network, distributing a unique DAI for each commodity, collecting real-time data in combination with an Internet of Things device, recording the real-time data on the block chain, enabling an intelligent contract to automatically execute a transaction and an event, and improving the transparency of the supply chain. According to the method, the process is transparent, the elliptic curve encryption algorithm is adopted to protect data security, access authority control is set, a user can quickly retrieve commodity data through DAI and enjoy efficient query service, in addition, user interaction interface simplified operation is provided, the transparency, security and efficiency of a supply chain are remarkably enhanced, and the method is suitable for a modern complex supply chain system.
