The Glamsterdam rehearsal on Sepolia brings in enshrined proposer-builder separation (ePBS) and block-level access lists. That moves the builder/proposer split from research into a fork on a December mainnet track.
- Oct 8Strengthened +2
A new Ethereum Research post prices the cost of censorship under multiple concurrent proposers and asks whether the design survives Sybil identities. Researchers are pricing a new economic attack surface before the redesign ships, as the thesis predicts.
