A Study on Resource Security under Legal Protection of e-Commerce Data Sovereignty Based on Blockchain Network

Abstract

With the growing demand for cross-border electronic data forensics, national sovereignty and international network security have ushered in great challenges, and how to achieve dynamic balance in various fields under cross-border electronic data forensics, advance the process of global cyberspace governance, reach international consensus, and achieve win-win cooperation is a question that China needs to solve. Based on the above status quo, a blockchain-based secure e-commerce system is researched and implemented. Using the distributed architecture of the blockchain system and the automatic execution feature of smart contracts, a secure transaction application system is designed to realize decentralization and solve the problem of untrustworthy intermediate parties. Data storage is based on the mechanism of combining blockchain and offchain databases to ensure data security, and the characteristic of blockchain can only be appended and read to prevent the system from being tampered. The database index and the storage structure of smart contract commodity information and transaction information are established to improve the query efficiency. The functional and performance tests of the system show that the transaction processing efficiency is high in the multinode environment, and the response time of order and commodity status query can reach 80 ms. The design and development process of the system is introduced in detail, which is an important reference value for the application of blockchain technology in e-commerce.
