With the rapid development of blockchain technology and step-by-step explorations of applications focusing. The data value circulation system driven by innovative technologies such as blockchain，big data，and privacy-preserving computing has become an indispensable pillar of the digital economy. This article introduces the value of data factor circulation and the challenges in data governance and innovation for the application of data circulation systems. Next，we analyze the main ideas of the integration of blockchain and privacy-preserving computing，including the use of the immutable nature of blockchain for privacy computing process tracing，and the use of blockchain in decentralized privacy-preserving computing orchestration and admission control among business stakeholders. After that，the design of ANTCHAIN blockchain-based privacy collaboration platform is proposed，including the innovative privacy-preserving collaboration architecture FAIR and its protocols，interfaces，language design，full data life cycle privacy protection，software and hardware integration and other technologies. Finally，we conclude this article with business applications of this platform in logistics finance，digital marketing and other scenarios.
