The coming twelvemonth is acceptable to beryllium important for Ethereum scaling. In 2026, the Glamsterdam fork volition bring cleanable parallel processing to the concatenation and ratchet up the state bounds to 200 million, up from 60 cardinal today.
A important fig of validators volition power implicit from reexecuting transactions to verifying zero-knowledge (ZK) proofs instead. This sets the Ethereum furniture 1 connected a way to standard up to 10,000 transactions per 2nd (TPS) and perchance beyond, though that people won’t beryllium deed successful 2026.
Meanwhile, information blobs volition summation (potentially up to 72 oregon much per block), enabling the furniture 2s (L2s) to process hundreds of thousands of transactions per second. L2s are becoming easier to usage arsenic well; ZKsync’s caller Atlas upgrade allows funds to enactment connected mainnet but commercialized successful the accelerated execution situation of chains successful ZKsync’s Elastic Network.
The planned Ethereum Interoperability Layer volition alteration seamless cross-chain cognition among L2s, privateness volition instrumentality halfway stage, and improved censorship absorption is targeted for the Heze-Bogota fork astatine the extremity of the year.
Ethereum successful 2026: The Glamsterdam fork
Ethereum developers are presently finalizing what Ethereum Improvement Proposals (EIPs) should beryllium included successful the Glamsterdam hard fork, expected successful mid-2026. The confirmed headliner changes are Block Access Lists and Enshrined Proposer Builder Separation. Neither sounds peculiarly interesting, but they person the imaginable to supercharge the blockchain up of the power to ZK tech.
At immoderate point, the halfway devs volition travel up with chill names for worldly similar “Firedancer,” but until then, we’re stuck with immoderate boring method names they choose.
Glamsterdam: Block Access Lists (EIP-7928)
Although “block entree lists” dependable similar a censorship scheme, the upgrade really makes “perfect” parallel artifact processing possible.
To date, Ethereum has been moving successful single-lane mode, with a precise agelong queue of transactions executed successful order, 1 aft the other. Block Access Lists alteration throughput to standard up to a multi-lane highway, with aggregate transactions processed astatine the aforesaid time.
The word refers to a representation included successful each artifact that was devised by the artifact producer, who executed everything archetypal connected immoderate fancy high-end equipment. The representation tells Ethereum clients which transactions impact which different transactions, accounts and retention slots and what the authorities differentials are aft the transaction. This allows them to parcel up the transactions and tally them connected aggregate CPU cores simultaneously without immoderate conflicts.
It besides enables clients to preload each the indispensable information from disk into representation first, alternatively than support going backmost to work the disk sequentially, which Trintinalia calls “the biggest bottleneck we have.”
Perfect parallel processing volition alteration Ethereum to tally astatine higher transactions per 2nd and person bigger artifact sizes without raising the state limit.

The process of separating artifact builders and proposers has already begun with MEV Boost, an out-of-protocol solution that uses centralized relays arsenic intermediaries and handles astir 90% of blocks. Enshrined Proposer Builder Separation (ePBS) integrates this process straight into Ethereum’s statement furniture for trustless operation.
The thought down separating the 2 is that artifact builders vie with each different to prime and bid transactions successful the champion mode imaginable to physique a block, portion proposers take which artifact to propose. The purpose is to mitigate maximal extractable value’s (MEV) centralizing unit and to amended security, decentralization and censorship resistance.
But from a scalability standpoint, the large payment of ePBS is that it provides much clip for the procreation and propagation of ZK-proofs passim the network. Validators are presently penalized for being slow, which disincentivizes waiting astir to validate ZK-proofs. EPBS volition supply much clip to person and validate ZK-proofs.
This tin springiness attesters much clip to person proofs (and provers much clip to make proofs), explained Ethereum researcher Ladislaus von Daniels, adding that ePBS decouples artifact validation from artifact execution and, successful that sense, ships different spirit of delayed execution.
“This makes opt-in zkAttesting overmuch much inducement compatible for validators.”
Ethereum Foundation researcher Justin Drake estimates that astir 10% of validators volition power to ZK aft this point, which volition alteration further state bounds increases.

The state bounds (which relates to throughput connected the L1) has already been accrued to 60 million. It should substantially summation successful 2026 — though there’s a scope of estimates arsenic to however precocious it volition go.
“I deliberation successful 2026, I would expect to spot 100 cardinal reasonably soon. Anything beyond that is astir apt conscionable excessively speculative to consider,” said Gary Schulte, elder unit blockchain protocol technologist connected the Besu client. He added that the displacement to delayed execution could marque higher state limits possible.

Tomasz Stańczak, co-director of the Ethereum Foundation, told the caller Bankless Summit that the bounds would summation to 100 cardinal successful the archetypal fractional of 2026 and predicted it would treble to 200 cardinal pursuing ePBS. Further improvements could mean up to 300 cardinal state per artifact is imaginable earlier the extremity of the year.
Ethereum creator Vitalik Buterin was much circumspect. In precocious November, helium said to “expect continued maturation but much targeted / little azygous maturation for adjacent year. eg. 1 imaginable aboriginal is: 5x state bounds summation unneurotic with 5x state outgo summation for operations that are comparatively inefficient to process.” Buterin cited things similar storage, precompiles and calls to contracts with ample declaration sizes.

Expect to spot immoderate of the EIPs held implicit from Glamsterdam successful this fork, but according to Forkast, the lone EIP presently connected the Considered for Inclusion database is Fork-Choice Inclusion Lists (FOCIL). This was up for Glamsterdam but was pushed aft a heated debate, arsenic it would person required excessively overmuch enactment and made beingness excessively difficult.
It’s not focused connected scaling but connected the cypherpunk perfect of censorship absorption by empowering aggregate validators to mandate the inclusion of circumstantial transactions successful each block.
“That is simply a censorship absorption mechanics that ensures that if astatine slightest you person portion of the web that’s honorable ... past you’re going to person your transaction included astatine immoderate point,” said Trintinalia.
Keep an oculus retired for portion 2, erstwhile we dive deeper into scaling the L1 with ZK-proofs successful 2026.
