The approaching 12 months is about to be essential for Ethereum scaling. In 2026, the Glamsterdam fork will carry excellent parallel processing to the chain and ratchet up the fuel restrict to 200 million, up from 60 million right this moment.
A big variety of validators will change over from reexecuting transactions to verifying zero-knowledge (ZK) proofs as an alternative. This units the Ethereum layer 1 on a path to scale as much as 10,000 transactions per second (TPS) and probably past, although that concentrate on gained’t be hit in 2026.
In the meantime, information blobs will improve (probably as much as 72 or extra per block), enabling the layer 2s (L2s) to course of tons of of 1000’s of transactions per second. L2s have gotten simpler to make use of as nicely; ZKsync’s latest Atlas improve permits funds to remain on mainnet however commerce within the quick execution setting of chains in ZKsync’s Elastic Community.
The deliberate Ethereum Interoperability Layer will allow seamless cross-chain operation amongst L2s, privateness will take middle stage, and improved censorship resistance is focused for the Heze-Bogota fork on the finish of the 12 months.
Ethereum in 2026: The Glamsterdam fork
Ethereum builders are at the moment finalizing what Ethereum Enchancment Proposals (EIPs) needs to be included within the Glamsterdam arduous fork, anticipated in mid-2026. The confirmed headliner modifications are Block Entry Lists and Enshrined Proposer Builder Separation. Neither sounds notably attention-grabbing, however they’ve the potential to supercharge the blockchain forward of the change to ZK tech.
In some unspecified time in the future, the core devs will provide you with cool names for stuff like “Firedancer,” however till then, we’re caught with no matter boring technical names they select.
Glamsterdam: Block Entry Lists (EIP-7928)
Though “block entry lists” sound like a censorship scheme, the improve really makes “excellent” parallel block processing attainable.
Up to now, Ethereum has been working in single-lane mode, with a really lengthy queue of transactions executed so as, one after the opposite. Block Entry Lists allow throughput to scale as much as a multi-lane freeway, with a number of transactions processed on the similar time.
The time period refers to a map included in every block that was devised by the block producer, who executed the whole lot first on some fancy high-end gear. The map tells Ethereum shoppers which transactions have an effect on which different transactions, accounts and storage slots and what the state differentials are after the transaction. This permits them to parcel up the transactions and run them on a number of CPU cores concurrently with none conflicts.

“With Block Entry Listing, we’re getting all of the state that modifications from transaction to transaction, and you might be placing that info within the block,” defined Gabriel Trintinalia, senior blockchain engineer with Consensys, who’s engaged on execution consumer Besu.
It additionally permits shoppers to preload all the required information from disk into reminiscence first, fairly than hold going again to learn the disk sequentially, which Trintinalia calls “the largest bottleneck we’ve.”
Excellent parallel processing will allow Ethereum to run at greater transactions per second and have greater block sizes with out elevating the fuel restrict.
Glamsterdam: Enshrined Proposer Builder Separation
The method of separating block builders and proposers has already begun with MEV Enhance, an out-of-protocol answer that makes use of centralized relays as intermediaries and handles roughly 90% of blocks. Enshrined Proposer Builder Separation (ePBS) integrates this course of straight into Ethereum’s consensus layer for trustless operation.
The concept behind separating the 2 is that block builders compete with one another to pick out and order transactions in one of the simplest ways attainable to construct a block, whereas proposers select which block to suggest. The purpose is to mitigate maximal extractable worth’s (MEV) centralizing strain and to enhance safety, decentralization and censorship resistance.
However from a scalability standpoint, the key advantage of ePBS is that it gives extra time for the technology and propagation of ZK-proofs all through the community. Validators are at the moment penalized for being gradual, which disincentivizes ready round to validate ZK-proofs. EPBS will present extra time to obtain and validate ZK-proofs.
This can provide attesters extra time to obtain proofs (and provers extra time to generate proofs), defined Ethereum researcher Ladislaus von Daniels, including that ePBS decouples block validation from block execution and, in that sense, ships one other taste of delayed execution.
“This makes opt-in zkAttesting far more incentive appropriate for validators.”
Ethereum Basis researcher Justin Drake estimates that round 10% of validators will change to ZK after this level, which is able to allow additional fuel restrict will increase.
Ethereum L1 fuel improve and L2 blob goal upgrades
The fuel restrict (which pertains to throughput on the L1) has already been elevated to 60 million. It ought to considerably improve in 2026 — though there’s a spread of estimates as to how excessive it should go.
“I believe in 2026, I’d count on to see 100 million pretty quickly. Something past that’s most likely simply too speculative to contemplate,” stated Gary Schulte, senior workers blockchain protocol engineer on the Besu consumer. He added that the shift to delayed execution may make greater fuel limits attainable.

Tomasz Stańczak, co-director of the Ethereum Basis, informed the latest Bankless Summit that the restrict would improve to 100 million within the first half of 2026 and predicted it could double to 200 million following ePBS. Additional enhancements may imply as much as 300 million fuel per block is feasible earlier than the tip of the 12 months.
Ethereum creator Vitalik Buterin was extra circumspect. In late November, he stated to “count on continued progress however extra focused / much less uniform progress for subsequent 12 months. eg. one attainable future is: 5x fuel restrict improve along with 5x fuel price improve for operations which might be comparatively inefficient to course of.” Buterin cited issues like storage, precompiles and calls to contracts with massive contract sizes.
Ethereum 2026 fork No. 2: Heze-Bogota
Count on to see among the EIPs held over from Glamsterdam on this fork, however in response to Forkast, the one EIP at the moment on the Thought of for Inclusion checklist is Fork-Selection Inclusion Lists (FOCIL). This was up for Glamsterdam however was pushed after a heated debate, as it could have required an excessive amount of work and made life too tough.
It’s not targeted on scaling however on the cypherpunk very best of censorship resistance by empowering a number of validators to mandate the inclusion of particular transactions in every block.
“That may be a censorship resistance mechanism that ensures that if a minimum of you’ve gotten a part of the community that’s sincere … then you definately’re going to have your transaction included sooner or later,” stated Trintinalia.
Maintain a watch out for half 2, after we dive deeper into scaling the L1 with ZK-proofs in 2026.
