Wu said that Ethereum co-founder Vitalik Buterin tweeted that he has long supported Tornado Cash developer Roman Storm and his privacy-related work, emphasizing that privacy is a necessary protection for individuals to guard against social, commercial, and even personal risks in both the digital and real worlds. Vitalik pointed out that having governments, police, and intelligence agencies hold all personal information does not ensure safety; in reality, government databases are often hacked, and relevant agencies frequently outsource work to private companies, leading to data being sold and potentially flowing to foreign adversaries.
