Description

From Whiteboard to Mainnet is a new podcast series co-hosted by Columbia University’s Center for Digital Finance and Technologies (CDFT) and the Ethereum Foundation’s Academic Secretariat. This episode is also co-hosted by the newly formed Columbia–Ethereum Center for Blockchain Protocol Design.

The series brings together academics and Ethereum ecosystem contributors for focused, candid conversations. Each episode explores a specific topic or open problem, pairing leading researchers from academia with contributors from the Ethereum Foundation to share and compare perspectives.

The third episode will be co-hosted by Fahad Saleh (Columbia University/University of Florida), and Shyam Sridhar (Ethereum Foundation), and will feature Agostino Capponi (Columbia University), Ruizhe Jia (Stanford University), Thomas Thiery (Ethereum Foundation), and Julian Ma (Ethereum Foundation) in a discussion around Proposer Builder Seperation, Payment for Order Flow, and Centralization risks in Ethereum. The session will begin with a discussion of the key insights from Agostino and Ruizhe’s work, followed by a broader conversation on how the Ethereum community has responded. It will conclude with a look at frontier topics such as BuilderNet and enshrined PBS (ePBS).
