a16z published an article stating: Blockchain is the key infrastructure for trust on the internet in the AI era. They emphasized that as AI technology advances, establishing trust and security through blockchain will become increasingly important. Blockchain's decentralized nature can help prevent fraud, ensure data integrity, and promote transparency across digital platforms. The article also discussed how integrating blockchain with AI can lead to innovative applications and a more trustworthy digital environment for users worldwide.

ChainCatcher Message, the team at a16z crypto published an article pointing out that as AI systems scale, the internet lacks native ways to distinguish humans from machines, and trust systems face challenges, while blockchain technology can provide solutions. The article summarizes the following five key roles:

Enhancing the cost of AI impersonation: By using decentralized human identity verification systems (such as World ID), limit the scale of fake identities and increase attack costs.

Decentralized identity verification: Blockchain grants users control over their own identities, avoiding single points of failure in centralized identity systems, while protecting privacy and resistance to censorship.

Creating universal “passports”: Blockchain-based identity layers enable AI agents to operate across platforms, carrying permissions and payment information, improving interoperability and preventing lock-in effects.

Supporting machine-scale payments: Utilizing blockchain micro-payments and smart contracts to achieve low-cost, fine-grained payment distribution, supporting economic activities between machines.

Strengthening privacy protection: Through zero-knowledge proofs, users can verify their identities without revealing specific data, preventing AI from abusing information for impersonation.

a16z believes that blockchain is a necessary infrastructure for building an AI-native internet, capable of restoring trust and supporting the healthy development of AI systems.
