The end of the Web has always been a topic of debate. Some have said that social networks would destroy it, followed by threats from mobile applications, but none of these prophecies have come true. However, this time, AI might truly be different. From the rise and fall of centralized platforms to the exploration of decentralized networks, the internet is facing an unprecedented paradigm shift. The involvement of AI not only reshapes the way information flows but also challenges the underlying infrastructure of existing networks. In this major upheaval, many see opportunities for blockchain technology to fill the gap—transparent, verifiable, censorship-resistant underlying protocols that may protect the essence of the internet in the AI era.
