Judge's point of view: Once an anonymous identity is cracked, the wider the disclosure of personal information in the public chain may be

Ding Yuxiang, a judge of the Beijing No. 1 Intermediate People's Court, published a commentary article "Working Together to Protect Personal Information Security (New Theory)". The article mentioned that the blockchain technology that people are relishing can implement privacy protection through encryption algorithms and has the characteristics of being difficult to tamper with. Once the anonymous identity information is cracked (although the difficulty is extremely large) or leaked, the more decentralized the public chain of the blockchain technology, the wider the scope of personal information disclosure.
