As more and more people accept Bitcoin, block chain technology has received extensive attention and research. Block chain is a decentralized open dean technology that combines data blocks with the chain structure in chronological order, and combines encryption, protocol mechanisms, and smart contracts. Block chain technology has the characteristics of decentralization, high security, difficult information tampering, traceability, and transparency. Therefore, more and more companies and institutions are focusing on block chain technology research. In the wide application of block chain technology, the current centralized transaction model of e-commerce has gradually exposed some problems, such as the obvious monopoly trend of third-party platforms caused by the excessive central power, the difficulty of cross-border transactions, and the insecurity of user privacy information. Difficulties in accountability for transaction disputes, numerous phishing websites, and proliferation of fakes. Moreover, the current block chain transactions lack legal supervision and protection, transaction efficiency is low, smart contract functions are limited and difficult to understand, and block chain is highly professional and difficult to be accepted by the general public. Based on this, this article proposes a product anti-counterfeiting traceability system using a dual-chain block chain based on an improved Virginia algorithm, analyzes the security of the traceability system, and verifies the feasibility of the system through simulation experiments. The further combination of chain block chain technology and product security field provides reference and reference.
