Abstract

With the acceleration of global economic integration, cross-border transactions are becoming more and more frequent. However, traditional cross-border transaction systems generally suffer from inefficiency, high cost and privacy leakage. In this paper, we study the privacy protection problem in cross-border transactions and propose a privacy protection scheme for cross-border transactions based on block-chain technology. First, this paper briefly introduces the basic principles of block-chain technology and its application scenarios in cross-border transactions. Second, to address the shortcomings of existing privacy protection technologies, this paper proposes a privacy protection scheme that combines data encryption technology, zero-knowledge proof and hybrid network. The scheme achieves automatic execution and verification through smart contracts, which effectively protects the privacy of cross-border transaction participants. Finally, the effectiveness of the privacy protection scheme proposed in this paper in improving the level of privacy protection for cross- border transactions is verified through experimental evaluation and result analysis. This study is important for promoting the development of cross- border transactions, improving transaction efficiency and protecting user privacy.
