The Role of AI in Web3 Security and Privacy Protection The decentralized nature of Web3 provides greater freedom but also brings challenges in security and privacy. AI technology plays a crucial role in this area. AI can monitor and prevent cyber attacks in real-time through pattern recognition and anomaly detection techniques, thus protecting user asset security. At the same time, AI can offer personalized services while safeguarding user privacy, such as achieving encrypted processing and secure sharing of data through privacy computing technology. This ability to balance security with personalized needs is one of the new qualitative applications that AI brings to Web3, providing possibilities for building a safer and more reliable digital economic environment.
