Ethereum has increased its block gas limit from 45 million to 60 million, signaling a bold new phase in network scaling just ahead of the Fusaka upgrade.
TLDR:
- Ethereum raised its block gas limit by 33 percent, now at 60 million.
- The increase supports more transactions per block, easing congestion for users and DeFi apps.
- Fusaka upgrade is due December 3, bringing PeerDAS and other scaling improvements.
- Developers aim for a 180 million gas limit within a year, possibly even more.
What Happened?
Ethereum has officially increased its block gas limit to 60 million, a move seen as both a short-term boost in throughput and the beginning of more aggressive network scaling. This decision comes just days before the highly anticipated Fusaka hard fork, which promises even greater performance enhancements.
Ethereum Doubles Gas Limit Ahead of Fusaka Upgrade
The gas limit defines how much computation each Ethereum block can handle. By increasing this from 45 million to 60 million, Ethereum can now process significantly more transactions, reduce delays, and support heavier smart contract loads.
Ethereum Foundation researcher Toni Wahrstätter announced the change on X, saying it reflects a year-long effort across the community. “Just a year after the community started pushing for higher gas limits, Ethereum is now running with a 60M block gas limit. That’s a 2× increase in a single year, and it’s only the beginning,” he wrote.

This limit increase was automatically applied on November 25 after more than half of Ethereum’s validators signaled their approval. It marks a rare and critical shift in Ethereum’s base-layer capacity.
Why the Timing Matters
The move comes just days before Fusaka, Ethereum’s next major upgrade, scheduled for December 3. At the center of this update is PeerDAS, a new system for data availability sampling designed to make rollups more efficient and scalable.
Vitalik Buterin, Ethereum’s co-founder, described PeerDAS as “key to Ethereum scaling.” He also emphasized that future changes will focus not just on increasing capacity, but on making operations more efficient, such as charging more for computationally expensive actions.
In testnet runs, Fusaka has already proven its ability to handle increased load and now heads to the mainnet with routine client updates, consensus improvements, and security hardening.
Tripling the Gas Limit: A Floor, Not a Ceiling
Ethereum educator Anthony Sassano said in a Bankless podcast that the 60 million gas limit is just the start. Developers have set their sights on 180 million as the new baseline, and possibly more.
He explained that tripling or even quintupling the gas limit could be achieved through cost rebalancing. That would mean reducing the gas required for simple ETH transfers while increasing fees for less efficient processes.
Ethereum’s scalability roadmap also includes Glamsterdam, a 2026 upgrade where some of these pricing and optimization strategies are expected to be implemented.
Core developers like Ben Adams echoed the enthusiasm on X, posting, “Remember when ‘double L1 gas’ sounded spicy on Twitter?” and “The Ethereum gas limit debate went from ‘too risky’ to ‘already live’ in under a year.”
What’s Driving the Change?
Three key developments made this gas increase viable:
- EIP-7623 added block-size safeguards at the protocol level.
- Client-level optimizations enabled handling of higher gas throughput.
- Months of successful testnet data showed stable block propagation under higher loads.
Additionally, Ethereum scaling networks hit a record 31,000 transactions per second recently, with Lighter leading the charge at over 5,400 TPS. These trends highlight the network’s increasing readiness for more load.
Daily Research News Takeaway
Honestly, it feels like Ethereum is finally hitting its stride with these changes. As someone who watches network upgrades closely, the gas limit doubling isn’t just technical; it’s practical. Cheaper transactions, better performance, and a smoother user experience are finally within reach. And with Fusaka just around the corner, I think we’re about to see the Ethereum ecosystem operate on an entirely new level. The real story here is momentum. Ethereum is scaling like never before, and it looks like it’s just getting started.
