Overview
- Glamsterdam, targeted for mid‑2026, would introduce Block Access Lists (EIP‑7928) to enable parallel transaction processing and scale gas limits from roughly 60 million toward about 100 million and potentially 200 million.
- Enshrined proposer‑builder separation would move block building into the protocol to reduce reliance on MEV‑Boost relays and to give validators time for zero‑knowledge proof workflows.
- Ethereum researchers estimate about 10% of validators could opt to verify ZK proofs after the changes, shifting part of validation from re‑execution to proof checking.
- Heze‑Bogota, planned for late‑2026, features Fork‑Choice Inclusion Lists to strengthen censorship resistance, with separate discussions considering Verkle Trees or state/history expiry to manage state growth.
- Proposals to raise per‑block data blobs to 72 or more would expand Layer‑2 capacity to hundreds of thousands of transactions per second in aggregate, though higher limits and parallelism would increase hardware demands and require extensive testing.
