PANews reported on October 22 that at the main forum of ETHShanghai 2025, Xiao Feng, Vice Chairman and Executive Director of Wanxiang Holdings, Chairman of Wanxiang Blockchain, and Chairman and CEO of HashKey Group, and Vitalik Buterin, co-founder of Ethereum, engaged in an in-depth dialogue on the three topics of AI, prediction markets, and ZK ID. Vitalik stated that the large number of people who participated in predictions on Polymarket during the US election was a success in itself. Traditional media and social media may be unable to judge the significance of an event, but prediction markets, through price signals, more quickly reflect reality and are becoming a new information medium. Prediction markets are not only applicable to large-scale events but, with the help of AI, can also accurately predict smaller ones. In the future, the integration of AI and prediction markets will make predictions more mainstream and intelligent. Regarding the AI sector, Vitalik suggested that blockchain defines the rules of the game, allowing AI to become a participant. With the rise of AI agents, they can independently issue tokens, participate in applications and governance, opening up a wealth of experimental space. Future research should further explore how to empower ecosystem development. However, he emphasized that AI should not replace humans but rather serve as a tool for them. Security remains a key concern, including the risk of hacking agents. He further mentioned the potential of ZK ID (zero-knowledge identity) in preventing AI abuse. ZK ID can help distinguish between real people and robots, while protecting privacy and supporting the development of low-risk sectors such as DeFi.PANews reported on October 22 that at the main forum of ETHShanghai 2025, Xiao Feng, Vice Chairman and Executive Director of Wanxiang Holdings, Chairman of Wanxiang Blockchain, and Chairman and CEO of HashKey Group, and Vitalik Buterin, co-founder of Ethereum, engaged in an in-depth dialogue on the three topics of AI, prediction markets, and ZK ID.
