Vitalik Buterin challenges AI authorship detection

• Ethereum co-founder Vitalik Buterin said no researcher or AI model has identified documents he claims to have published anonymously 13 days after issuing the challenge.
• Buterin released a new hint, saying many AI searches excluded document categories that should have been analysed.
• The experiment is testing whether artificial intelligence can reliably identify anonymous authors through writing style analysis.

Ethereum (CRYPTO:ETH) co-founder Vitalik Buterin said no researcher or artificial intelligence system has successfully identified documents he claims to have published under another name after 13 days of public analysis.

The challenge, first issued on 22 June, asked researchers to use writing-style analysis to identify anonymous Ethereum-related documents authored by Buterin, who estimated the relevant dataset contains between 200 and 2,000 possible documents.

"So far no one has found it. My only hint is that I would encourage people to somewhat broaden their search; I've seen quite a few searches and AI scripts that fail to include categories of documents that really should be included," said Buterin.

Buterin said many AI-powered searches focused on a limited range of official publications while overlooking other categories of documents that could contain the anonymous work, suggesting the search methodology rather than the underlying models may have limited the results.

The experiment continues without a confirmed solution, and Buterin has not disclosed which documents were published anonymously or when he intends to reveal their identities.

The challenge forms part of Buterin's broader interest in privacy and the limits of AI-based authorship attribution, particularly in assessing whether modern language models can reliably deanonymise online writers.

The results so far indicate that identifying authors solely through writing patterns remains difficult in complex datasets, although the experiment does not establish broader conclusions about the overall capabilities of artificial intelligence.

At the time of reporting, Ethereum price was $1,792.37.
