# Ethereum Redesigns Block Production

Ethereum will keep reworking who builds, proposes and orders blocks to counter concentration among builders and staking operators, and each redesign will open new economic attack surfaces that researchers must price before it ships.

## Recent evidence

- [confirms] Ethereum researchers price the cost of censorship under multiple proposers and warn of orphaned bytecode in state redesign (2026-10-08): 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.
- [confirms] Ethereum's Glamsterdam upgrade goes live on Sepolia with a 200 million gas ceiling that early blocks leave half empty (2026-10-08): 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.
