Wu Shuo learned that Ethereum co-founder Vitalik Buterin posted a statement saying that recent opinions suggest AI text analysis will make it difficult to maintain network anonymity, so he decided to conduct a public experiment: inviting the public to find an Ethereum-related document that he anonymously wrote and published within this decade, with "moderate importance," to test AI's ability to identify anonymous authors. Vitalik stated that he is also unsure whether this challenge is easy or difficult.
