Glamsterdam Explained: Every EIP in Ethereum's Next Upgrade

Tue, 21 Jul 2026 07:58:00 +0000

Glamsterdam is the next Ethereum hard fork after Fusaka, and it is shaping up as the most structural release the network has shipped in years. It moves the block-building auction into the protocol itself, puts a consensus-verified state diff inside every block, and reprices the corners of the EVM that stood in the way of much higher gas limits. Multi-client devnets have been running the full slate since June 2026, and mainnet activation is targeted for the second half of the year.

What Is ePBS? Ethereum's Enshrined Proposer-Builder Separation (EIP-7732), Explained

Mon, 20 Jul 2026 08:12:00 +0000

ePBS stands for enshrined proposer-builder separation. It is the change, specified in EIP-7732, that moves Ethereum’s block-building marketplace out of trusted off-chain middleware and into the protocol itself. Today, a validator who wants a professionally built block hands the deal to a relay, an unpaid third party that both sides simply have to trust. Under ePBS the builder’s signed bid goes into the beacon block directly, payment is enforced by consensus, and the relay’s trust role disappears. It ships as the headline consensus change of Glamsterdam, the hard fork after Fusaka, currently targeted at mainnet in the second half of 2026.

Lean Ethereum: Vitalik's Third Rebuild of the Protocol, Explained

Mon, 06 Jul 2026 10:00:00 +0000

Two weeks ago, Ethereum researchers met in Berlin to keep charting the protocol’s long-term trajectory, picking up threads from the client-team discussions held in Svalbard back in April. The output is an updated strawmap, the community’s deliberately provisional sketch of where the protocol is headed, and a set of high-level takeaways that Vitalik Buterin published on July 4. The framing that ties them together is a name: Lean Ethereum.

It helps to be precise about what that name means, because it is easy to file under “another roadmap.” Lean Ethereum is not a single one-shot upgrade. It is a collection of improvements that will come online over the course of three or four years. But make no mistake: this is the third major iteration of Ethereum, in the same way that the Merge was the second. Almost every major piece of the protocol is on the table to be replaced, and the through-line is simplification, cleanup, and future-proofing, done in a way that minimizes disruption to the applications already running. Ethereum has done exactly this before with the transition from proof-of-work, so the precedent for a deep rebuild that users barely feel already exists.

Block-Level Access Lists Explained (EIP-7928)

Fri, 03 Jul 2026 10:00:00 +0000

Glamsterdam, the next Ethereum upgrade after Fusaka, has two headline changes. The consensus-layer half is ePBS, EIP-7732, which restructures how blocks get built and has absorbed most of the attention. The execution-layer half is EIP-7928, Block-Level Access Lists, and it is arguably the more practical change for anyone whose job is consuming Ethereum data rather than producing blocks. It is also further along than most people realize: Geth 1.17.4 already constructs and verifies BALs during block execution and serves them over the new eth/71 wire protocol, ahead of the fork activating anywhere public.
