💮 Whiteboard: An Overview of Credible Commitment Devices

“What is the major value proposition of crypto?”
“And why, from just first principles, this value proposition induces MEV?”

These are some of the questions discussed in this first installment of Flashbot’s new :white_flower: Whiteboard Series to explore and explain ideas around MEV, whose theme will be structured around answering: “how do we unlock the magic of trustless collaboration?”

format: 30min - 1hr episodes, one invited guest.

In this first episode, we share mental models on formulating crypto as permissionless credible commitment devices using (cooperative) game theory, then dive into the limits of the tradeoff space in mediating games and meta-games played using those devices.

Summary: A major value proposition of crypto is that users can trustlessly collaborate by making credible commitments of their actions. In this episode, we discuss mental models to think about permissionless credible commitment devices through the lens of game theory, with the (un)surprising observation that MEV arises as a necessity from the use of such devices.
