While the market obsesses over ETF flows and AI tokens, one of the most consequential shifts in Ethereum’s technical history is quietly underway. The network’s core developers are pushing the block gas limit “toward and beyond” 100 million — a more than 3x increase from where the network stood at the start of 2025. This isn’t a minor configuration tweak. It’s a fundamental expansion of Ethereum’s computational capacity that could drastically lower L1 fees, unlock new categories of on-chain applications, and change the calculus for what’s possible on the mainnet itself.
The Timing: Why 100M Gas Matters Right Now
The push for a higher gas limit is not happening in a vacuum — it’s a direct response to unprecedented, real-world network demand. In February 2026, Ethereum L1 processed a record-breaking 2.9 million transactions in a single day. Meanwhile, the broader Ethereum ecosystem, including Layer 2 rollups, hit a combined peak of 31,000 transactions per second (TPS) in late November 2025, according to GrowThePie data. This surge in activity, driven by both retail users and institutional adoption, creates a clear and urgent need to expand the base layer’s capacity.
The 100M gas target is a central pillar of the Ethereum Foundation’s 2026 Masterplan, which organizes development into three tracks: Scale, Improve UX, and Harden the L1. Under the Scale track, the Foundation explicitly set the goal of pushing the gas limit “toward and beyond” 100 million. This is not an aspirational target — it’s a coordinated engineering effort backed by client teams across the entire ecosystem.
The Quote: A Unified Effort
“The Scale track brings together what was previously split across Scale L1 and Scale Blobs into a single, unified effort. This reflects a practical reality: the work of increasing L1 execution capacity and expanding data availability throughput is deeply intertwined.”

How It’s Possible: Glamsterdam and EIP-7928
Raising the gas limit safely requires the underlying infrastructure to handle the increased load without compromising block propagation times or node stability. This is where the Glamsterdam upgrade, slated for the first half of 2026, becomes essential. One of its most important components is EIP-7928: Block-level Access Lists (BALs).
BALs work by requiring blocks to pre-declare all the accounts and storage slots they will access during execution. This seemingly simple change has a profound effect: it allows execution clients to verify blocks in parallel rather than sequentially, dramatically reducing the time needed to process a full block. The trade-off is a small data overhead — roughly 45 KiB per block at a 36M gas limit — but the payoff is the ability to safely handle a much higher gas limit without risking network instability. Without this kind of foundational work, simply raising the gas limit would be reckless.
The Numbers: What 100M Gas Actually Means
The practical impact of a higher gas limit is straightforward: more transactions per block, lower fees during periods of high demand, and more room for complex smart contract interactions. The table below shows the progression from the 30M limit of early 2025, through the current 60M limit reached in November 2025, to the 100M target for 2026. All figures are based on a 12-second block time and 21,000 gas per simple ETH transfer.
| Metric | 30M Gas Limit (Early 2025) | 60M Gas Limit (Current) | 100M Gas Limit (2026 Target) |
|---|---|---|---|
| Max Txs/Block (Simple Transfer) | ~1,429 | ~2,857 | ~4,762 |
| Theoretical Max TPS | ~119 | ~238 | ~397 |
| Impact on L1 Fees | High during congestion | Moderate | Low & Stable |
The Tension: L1 vs. L2 Scaling
The push to scale Layer 1 directly challenges the prevailing narrative that all user activity must eventually migrate to Layer 2 rollups. While L2s remain critical for hyperscale applications and will continue to grow, a more powerful L1 changes the economic trade-offs for developers and users alike. With a 100M gas limit, base layer fees could become low enough for a much wider range of applications to remain on L1, benefiting from its unparalleled security and decentralization guarantees. This has sparked a genuine debate within the community, with some voices arguing for even more aggressive L1 scaling, while others caution that the risks of state bloat must be managed carefully.
The Risks: State Bloat and Vitalik’s “Targeted Scaling”
The primary risk of a higher gas limit is state bloat. As more transactions are processed, the size of Ethereum’s state — the complete dataset of all account balances, smart contract code, and storage — grows continuously, increasing the hardware requirements for running a full node. In a December 2025 report, the Ethereum Foundation warned that roughly 80% of the state had not been accessed in over a year, yet every node on the network must store it in its entirety. This growing storage burden risks pushing node operation out of reach for ordinary users and concentrating it among a small number of large providers, which would undermine Ethereum’s decentralization.
To counter this, core developers are actively working on long-term structural solutions. State Expiry would archive old, unused state data and allow it to be restored with cryptographic proofs if needed. State Archives would create a two-tier system of “hot” (frequently accessed) and “cold” (rarely accessed) state. Partial Statelessness would allow individual nodes to store only a subset of the state, reducing the burden on any single operator. In the shorter term, Vitalik Buterin has advocated for a “targeted scaling” approach: future gas limit increases should be paired with higher gas costs for computationally intensive operations — such as heavy precompiles and complex arithmetic opcodes — to prevent abuse and preserve network efficiency even as raw capacity grows.
The Bottom Line: A More Powerful Mainnet
The 100M gas limit is more than just a number on a configuration dial. It represents a strategic, coordinated decision to reinvest in the capacity and economic viability of Ethereum’s base layer. It ensures that while Layer 2s continue to flourish, the L1 mainnet does not become a ghost town reserved only for whales and rollup settlement transactions. For everyday users, it promises lower fees and a more reliable experience. For developers, it opens up new possibilities for building directly on the most secure and decentralized smart contract platform in the world. This is the story of Ethereum quietly doing the hard work — and it’s a story the broader market has largely missed.
