Ethereum’s 2026 Gas Limit Surge: How BALs & ePBS Ignite the Next Scaling Revolution

Ethereum just flipped the switch. The long-anticipated gas limit increase is live—and it's not a gentle nudge. It's a full-throttle overhaul powered by two core upgrades: Block Auction Layers (BALs) and enshrined Proposer-Builder Separation (ePBS). This isn't just about cheaper fees; it's about redefining the network's economic and security model.
The Mechanics of the Move
BALs introduce a competitive auction for block space, moving beyond first-price gas auctions. This creates a more efficient market where value flows to the most urgent transactions, not just the deepest pockets. Meanwhile, ePBS formally separates the roles of block proposing and building, a move that cuts centralization risks at their root and makes censorship far more difficult. Together, they don't just raise the limit—they rebuild the highway while the traffic keeps moving.
Implications for Builders and Users
For developers, this means a new playground. Applications that were once gas-prohibitive—think fully on-chain gaming, complex DeFi derivatives, or high-frequency micro-transactions—suddenly enter the realm of the possible. For users, the promise is simpler: more predictable costs and a smoother experience, even during market frenzies. The network's capacity isn't just scaling; it's evolving.
The Bullish Backbone
This upgrade cements Ethereum's focus on sustainable scaling through its core protocol, a stark contrast to relying solely on secondary layers. It strengthens the base layer's value proposition, making ETH not just a transactional asset but the fundamental security commodity for a vastly expanded ecosystem. The timing is no accident—it's a direct response to the demands of a maturing market that's tired of promises and wants throughput.
One cynical finance jab? Wall Street still thinks a basis point is volatile; try watching gas prices pre-2026. This upgrade might finally make Ethereum's fee market boring enough for them to understand—and that's when the real institutional money shows up.
Ethereum's 2026 pivot proves a core crypto truth: infrastructure upgrades are the ultimate bullish catalyst. This isn't a patch; it's a new foundation. The gas limit increase is just the most visible metric. The real story is the more resilient, efficient, and capable network emerging beneath it. The race for the future of finance isn't won by the fastest chain, but by the smartest economy. Ethereum just leveled up.
Ethereum starts large gas limit increases in 2026 through BALs and ePBS
Vitalik then pointed to Bitcoin in 2009, saying:-
“Bitcoin (2009): highly decentralized, consensus, but low bandwidth because it’s not “distributed” in the sense of work being split up, it’s replicated. Now, ethereum with PeerDAS (2025) and ZK-EVMs (expect small portions of the network using it in 2026), we get: decentralized, consensus and high bandwidth. But now it’s time to talk about what this combination means for Ethereum.”
Vitalik said these upgrades are already running code, not theory. Data availability sampling is active on mainnet today. zk-EVMs already hit production performance levels. Safety checks are the final step, and Vitalik traced that work back ten years, starting with his first data availability research commit and later zk-EVM experiments that began around 2020.
The rollout plan is staged. In 2026, Ethereum expects large gas limit increases that do not depend on zk-EVMs, driven by BALs and ePBS. That same year should also bring the first chances to run a zk-EVM node on parts of the network, according to Vitalik.
From 2027 through 2030, Ethereum plans even larger gas limit jumps as zk-EVMs become the main block validation method. “ZKEVM becomes the primary way to validate blocks on the network,” Vitalik wrote.
Another piece is distributed block building. Vitalik said the long-term goal is a setup where a full block is never built in one place. He said this is not urgent, but worth building toward. In Vitalik’s words:-
“Even before that point, we want the meaningful authority in block building to be as distributed as possible. This can be done either in-protocol (eg. maybe we figure out how to expand FOCIL to make it a primary channel for txs), or out-of-protocol with distributed builder marketplaces. This reduces risk of centralized interference with real-time transaction inclusion.”
Vitalik said that it also improves geographic fairness. The Ethereum Foundation has it stated on its website that higher gas limits on Ethereum are made SAFE by zk-EVMs increase capacity, cut congestion, and stabilize fees.
The Foundation said:- “Bringing zkEVMs to L1 is a multi-faceted effort. Our work is organized into three Core workstreams, with parallel progress on client implementations.”
