I've been building an L1 blockchain called NOVAI. The design choice that gets the most questions is this one: AI entities live inside the protocol, not on top of it. There is no VM. No deployable contracts. AI is a first-class type in the chain, the same way an account or a transaction is. This post is about what that means in practice, why I made the call, and what it costs. How AI on chain usually works If you've looked at AI-on-chain projects in the last while, the pattern is roughly this. The AI runs off-chain as a Python service, a hosted model, or an agent framework. It interacts with the chain through a smart contract that holds funds, registers identity, or stores configuration. Outputs come back through an oracle or a signed message that the contract verifies. This works in the sense that you can ship something. But it leaves the chain blind.
