Andreessen Horowitz’s a16z crypto arm suggests that blockchains could guide artificial intelligence towards user ownership and open standards. The report suggests that core context and agent passports should be stored in self-custodial wallets, allowing instant access to preferences without repeated training. A chain-based identity layer would allow agents to carry verifiable records of owners, capabilities, and payment details across platforms. Proof-of-personhood systems could help screen bots as generative models proliferate. The report also promotes decentralized physical infrastructure networks, on-chain synchrony layers, micropayments, and immutable ledgers for managing intellectual property. It also suggests smart contract licensing and wallet-based zero-knowledge proofs for advertising. The report concludes that intertwining blockchains and machine learning could preserve an open internet by embedding incentives, provenance, and governance directly at the protocol layer.
