Proof of agency and fraud defenses

In this episode of Possible, Reid Hoffman and Aria Finger talk with Sean Neville, co-founder of Circle and architect of USDC, about building the financial infrastructure for an AI-driven economy. Now leading Catena Labs, Neville is working on what he calls the first AI-native bank—designed for autonomous agents that can transact, comply, and interact without humans in the loop. The conversation explores what breaks when AI tries to use today’s financial rails, why stablecoins may power machine-to-machine commerce, and why new concepts like “Know Your Agent” could become the foundation of trust in an AI financial system.
