Original: The Architecture of On-Chain AI Agent Execution: Beyond Smart Contracts

Short summary

Real on-chain AI agents don't bolt AI onto smart contracts — they invert the architecture so the agent becomes the primary execution context and the blockchain is its state layer. The article describes agent runtimes with persistent memory pools, decision engines using off-chain or verifiable inference, and action executors. Key constraints include gas costs, finality delay, and state bloat. Platforms like BBIO are building this runtime layer.

  • On-chain AI agents invert traditional smart contract architecture
  • Agent runtimes need persistent memory, decision engines, and action executors
  • Key constraints: gas costs, finality delay, and state bloat

Generated with AI, which can make mistakes.

Is this a good recommendation for you?
