One emerging approach to AI on-chain integration is embedding AI directly into the transaction layer itself. Rather than treating AI as a peripheral component, this architecture weaves inference capabilities into the core execution flow. Here's how it works: whenever a smart contract invokes an AI model, the inference process executes atomically—completing within a single transaction. This means validation happens together with the computation. Full nodes execute and verify the transaction, while specialized inference nodes handle the model computation in parallel. The result is a more cohesive system where AI and blockchain operations aren't fighting each other but moving in lockstep.
