Research on Anti-Tampering Technology of Procurement System Based on Blockchain

With the increasing number of users and the continuous expansion of functions in the power procurement system, various problems have been brought to the data in the power grid, especially the loss and damage of data after multiple circulation in various business systems, which has led to a decrease in credibility and difficulty in tracing. Based on this, this paper designs a ternary structure model of blockchain elec-tricity information collection system, proposes a practical hash algorithm based on the ternary structure of blockchain electricity information collection system to prevent tampering, and conducts simulation verification. The experimental results show that the anti-tampering encryption algorithm of the blockchain electricity information collection system ternary structure can improve data quality, thereby enhancing the credibility of business data. At the same time, this structure enhances the traceability ability of data, greatly improving the security of data exchange and use in the collection system.
