In recent years,a large number of new energy entities have connected to power trading platforms,and core business data volume has surged,resulting in issues such as excessive operational pressure,data insecurity,and opaque transactions on the current centralized power trading platform.Blockchain is essentially a distributed account book with decentralized characteristics,which is difficult to tamper with and has high security technical features.The application of Inter planetary file system(IPFS)in blockchain can reduce the size of data stored in the blockchain,have the function of file deduplication,and effectively avoid some security issues and limitations in centralized storage.This paper proposed a power security trading platform model based on IPFS and blockchain technology,which achieved data storage optimization and established a market credit mechanism.Simulation experiments show that the proposed model can effectively alleviate the storage pressure on physical nodes,improve system operation efficiency,and effectively quantify the credit of market entities.
