On-chain mechanisms that rely on external dependencies, such as oracle operators, tend to focus on decentralizing them. AmPO demonstrates another path: to design them away. AmPO removes the need for the mechanism to know the market price through an external dependency by making the option decay in a predictable manner over time and requiring a fixed exchange of assets at exercise time. During my talk, I will explain this mechanism and how it is designed to be trust minimized. As DeFi continues to be adopted and relied on, building mechanisms with fewer trusted external dependencies reduces the attack surface and the ability to censor protocols.
