[a16z crypto: Blockchain is Even More Necessary in the AI Era] Foresight News reports that a16z crypto stated in an article that AI is generating voice, video, and text at extremely low costs and enabling large-scale "human-like" interactions, which is challenging the internet's trust system based on the premise of "one account corresponding to one real user." They believe blockchain can complement the foundation: - By implementing a "decentralized proof of personality" mechanism, it can increase the cost for attackers to impersonate at scale, allow users to self-manage their identities, and enable cross-platform compatibility. - Create portable and universal "passports" for intelligent agents, enhancing their identity-carrying capacity, permissions, and reference information for payment endpoints, while enabling verification from any location to improve agents' anti-forgery capabilities. - Utilize L2, smart contracts, and other technologies to support machine-scale micropayments and programmable revenue sharing. - Combine zero-knowledge proof technology to allow users to prove specific facts, such as passwords or ID numbers, without exposing underlying data.
