摘　　要：基于区块链的充电交易数据存储未考虑到链上存储成本过高,提出一种结合区块链技术和星际文件系统(IPFS)的高效链式交互的充电交易数据存储模型CTDC。将区块链上存储扩展为结合IPFS的链下存储,依靠区块链的透明性和不可篡改性仅存储对应数据量内容哈希值。经过仿真实验验证,CTDC模型在数据上传阶段所需时间仅需云存储模型的10%左右,在数据下载阶段所需时间相对于云存储模型减少50%,突出了该模型在充电交易数据存储方面的高效性和低成本优势。Blockchain-based charging transaction data storage does notconsider the high cost of on-chain storage,and we propose a high-efficiency chain interaction charging transaction data storage model CTDC that combines blockchain technology and interplanetary file system(IPFS).The storage on the blockchain was extended to the off-chain storage combined with IPFS,relying on the transparency and immutability of the blockchain to store only the Hash value of the corresponding amount of data.Through simulation experiments,the CTDC model only needs about 10%of the time required for the cloud storage model during the data upload phase.The time required for the data download phase is reduced by 50%compared with the cloud storage model,highlighting the model s advantages of high efficiency and low cost in charging transaction data storage.
