Xi Yuemin, Chinese Academy of Social Sciences: Blockchain technology objectively adapts to the new requirements of data compliance and personal information protection

On August 14th, Xi Yuemin, a researcher at the Institute of Law of the Chinese Academy of Social Sciences, published a paper titled “Three Challenges in Improving the Construction of Data Rule of Law”. The article stated that blockchain technology objectively adapts to the new requirements of data compliance and personal information protection, in terms of data security. Play an important role. As a new way of Internet data recording, dissemination and storage, it forms a decentralized distributed database through consensus mechanism and encryption technology, and is characterized by independence, reliability, openness, transparency, security and traceability. Thus, the transformation of the Internet from information dissemination to value transfer and the security maintenance of multi-party information are realized. Since the consensus mechanism of the blockchain is applicable to different application scenarios, a necessary balance between efficiency and security is achieved. The problem is that the current blockchain technology still faces some technical problems in the large-scale application level. It needs to solve the contradiction between the security and sharing of the data privacy of the organization or enterprise, and the verification. It also needs to ensure the high-performance operation of the system under the full encryption of the data. . Although some blockchain companies in the market try to protect the privacy by hashing the hash value, but the effect is not satisfactory, there are still some technical defects.
