In this episode of Credible Commitments I talk to Mike Neuder, PHD student at Princeton University. Mike gives a masterclass on ePBS breaking down the mechanism, the microstructure, the incentives, and likely consequences. Next we dive into PropAMMs on Ethereum focusing on the data. The conversation shifts to ETH as a store of value, issuance, and MEV burn. Finally, we preview the 2026-2027 NBA season.
