According to Odaily Planet Daily, Ethereum founder Vitalik Buterin responded to a tweet on the X platform, talking about the change in his way of thinking. He said that compared with ten years ago, the economic factors involved in his thinking have decreased.
He tried to invent a mathematically provably optimal governance mechanism, but found some fundamental impossibilities and realized that the key to success or failure lies in factors such as the degree of coordination among participants.
In the past, math was a big part of his identity, and he was passionate about cryptographic protocols. Now, he uses math more to make rough initial guesses than to explain average-case behavior.
