Web3, as a decentralized, open, and transparent new paradigm of the internet, has an inherent synergy with AI. Under the traditional centralized architecture, AI computing and data resources are subject to strict control, facing numerous challenges such as computational bottlenecks, privacy breaches, and algorithmic black boxes. On the other hand, Web3, built on distributed technologies, can infuse new vitality into AI development through shared computing networks, open data markets, and privacy-preserving computation. Simultaneously, AI can empower Web3 with capabilities like optimizing smart contracts and anti-cheating algorithms, aiding in the ecosystem's construction. Therefore, exploring the convergence of Web3 and AI is crucial for building the next-generation internet infrastructure and unlocking the value of data and computing power.
