PANews reported on April 14 that Vitalik Buterin wrote an article today saying that he supports privacy not only because it is a guarantee of personal freedom, but also the cornerstone of social order and technological progress. The article pointed out that decentralization and privacy are inseparable, and the current AI and big data have greatly increased the risk of centralized control of personal information. Vitalik emphasized that cryptographic technologies such as ZK-SNARKs are empowering to protect identity information and achieve secure data computing. He called for strengthening the open source, universality and credibility of digital privacy tools to counter the potential trend of global data hegemony.
