Why Does the AI ​​Era Need Blockchain? @a16zcrypto First, decentralized proof of human uniqueness significantly increases the cost of AI impersonating humans on a large scale, filling the gap left by the ineffectiveness of traditional CAPTCHA. Second, on-chain identities allow users to manage their identities autonomously, preventing platform monopolies and censorship while maintaining privacy. Third, blockchain can provide AI agents with a universal identity passport across platforms, carrying permissions and payment capabilities. Finally, combining L2, smart contracts, and zero-knowledge proofs, blockchain can support the micropayment and privacy-preserving economic system required by AI. twitter.com/CryptoWesearch/sta...
