Autonomous AI agents are proliferating across finance, logistics, and enterprise operations, but lack accountability mechanisms for their actions. Researchers and crypto-native investors are proposing blockchain as a governance layer through immutable ledgers, smart contracts, and decentralized identity protocols. Research presented at IEEE ICCA 2025 described an architecture using permissioned blockchain alongside smart contracts to monitor the full perception-reasoning-action cycle of AI agents. Major players including a16z crypto and Franklin Templeton have identified this need, with Franklin Templeton calling agentic AI a potential killer use case for blockchain technology. No commercially dominant product exists yet at scale, though stablecoins are seen as well-suited for autonomous machine-to-machine transactions.
