Woofun AI reports that Vitalik Buterin has declared a winner for the AI anonymity identification challenge he initiated. The experiment involved writing EIP-7503 (Zero-Knowledge Wormhole) in Chinese in 2024 using Qwen2.5 and manual edits to hide his identity.

The analysis revealed that while prose style was successfully obscured, the AI identified the author by detecting unique thinking habits in mathematics and algorithm explanations. This detection method completely bypassed the obfuscation strategy focused solely on text style.
