Ethereum activates a major capacity upgrade this week as the network’s validator set successfully forces an Ethereum gas limit increase to 60 million gas per block. The adjustment, which became effective on November 25, 2025, expands the blockchain’s base layer throughput by approximately 33%, offering immediate relief for data congestion just days before the scheduled Fusaka hard fork.
Validators Coordinate the 33% Ethereum Gas Limit Boost
Unlike typical protocol upgrades that require complex software implementations, this scaling measure was achieved through decentralized consensus. Data confirms that over 513,000 validators, surpassing the critical 50% signaling threshold, manually configured their nodes to accept larger blocks.
This coordination raised the target from the long-standing 45 million gas ceiling to the new 60 million standard. Toni Wahrstätter, a researcher at the Ethereum Foundation, confirmed the successful transition.
“Just a year after the community started pushing for higher gas limits, Ethereum is now running with a 60M block gas limit,” Wahrstätter stated on November 27.
The move represents the most significant capacity adjustment since the EIP-1559 upgrade in 2021, signaling a shift in validator sentiment regarding the network’s hardware capabilities.
Unlocking Layer 2 Speed
The primary economic driver behind the Ethereum gas limit increase is the burgeoning Layer 2 ecosystem. Rollups such as Arbitrum, Optimism, and Base consume mainnet gas to settle batches of transaction data.
By increasing the size of each block, Ethereum can ingest more of this data per 12-second slot.
Market metrics indicate the upgrade had an immediate impact. Following the adjustment, aggregate throughput across the Ethereum ecosystem reportedly hit a peak of 31,000 transactions per second (TPS) on November 27.
This suggests that the additional block space is being utilized to settle higher volumes of rollup activity, potentially lowering gas fees for end-users on secondary networks.
The Centralization Trade-Off
While the capacity boost addresses scalability, it reignites debates regarding node centralization. Larger blocks require more bandwidth to propagate and more storage to maintain the state ledger.
Infrastructure analysts warn that a permanent move to 60 million gas accelerates “state bloat.” This increases the hardware burden on individual node operators, potentially favoring institutional data centers over home stakers.
However, early monitoring since the November 25 activation has shown no significant spike in missed blocks or network instability, validating the validators’ assessment of current hardware readiness.
The Path to Fusaka
This parameter change serves as a prelude to the Fusaka (Fulu-Osaka) hard fork, scheduled for epoch 411392 on December 3, 2025. While the gas limit increase expands general execution space, Fusaka will introduce PeerDAS (Data Availability Sampling) to specifically expand “blob” capacity for rollups.
Chain Street’s Take
Ethereum’s 60M gas limit marks the network’s biggest base-layer expansion in years, giving rollups fresh room to breathe just ahead of Fusaka. The upgrade buys throughput now, but it also sharpens long-running concerns that higher block sizes push the network toward heavier, more centralized infrastructure.
