[Vitalik: Anonymity Experiment Has Been Running for 13 Days, Still No One Has Found the Target Document] Foresight News reports that Ethereum co-founder Vitalik Buterin posted on the X platform stating that the anonymity experiment he initiated has been running for '13 days,' and so far, 'no one has found it.' He added a hint, encouraging everyone to 'slightly expand the search scope,' and noted that he has observed many search efforts and AI scripts missing categories of documents that should have been included. Previously, Vitalik had posted that there have been recent claims suggesting that AI text analysis will make online anonymity difficult to maintain. In response, Buterin decided to 'sacrifice some of his own anonymity' to conduct a test: at some point in this century, he authored a published document of medium importance to Ethereum, aiming to see if the community could identify the true author of the document through analysis.
