lean Ethereum Part 5: Devnets & Upgrade Coordination with Will and Raúl

About this episode

In this episode, Nico Mohnblatt chats with Will Corcoran and Raúl Kripalani about devnets and upgrade coordination in Ethereum.

https://youtu.be/Ul2bs8INF0k In this episode Nico Mohnblatt chats with Will Corcoran and Raúl Kripalani from the Ethereum Foundation . This is part 5 in the 6-part leanEthereum miniseries, shifting focus from the cryptographic primitives and LeanVM stack to the real-world integration happening through devnets, specs, and cross-team coordination. They dive into the human coordination layer, how independent teams align on post-quantum signatures, SNARK aggregation, and protocol changes, plus the networking upgrades needed for larger payloads. Raúl explains the shift from today's libp2p stack to a purpose-built Eth P2P next-gen version optimised for Ethereum's workloads, including better broadcast layers, erasure coding, and control planes to handle bandwidth competition between execution and consensus layers.
