Polygon, Eigenlayer, Sentient and others held the Open AGI Summit at EthCC to jointly discuss the issue of open and closed AI. Sandeep Nailwal, co-founder of Polygon and Sentient, elaborated on the key nodes facing humans and centralized AI. He advocated the implementation of an open world through blockchain to achieve transparency and fairness, rather than a closed world dominated by large enterprises. Nailwal also stated that "the rapid development of centralized AI and its integration with daily life has brought humanity to the crossroads of two future worlds. On the one hand, we can choose a closed world. This world is controlled by a few closed-source models operated by large enterprises. On the other hand, we can choose an open world. In this world, the model is open-source by default, and the reasoning is verifiable. The open world is the world we want to live in, but it can only be achieved by using blockchain to make AI more transparent and fair. "
