Ethereum Network Gas Limit Raised Ahead of Significant Upgrades

Ethereum developers are actively engaged in the strategic scaling of the Layer 1 network, gearing up to implement the upcoming significant protocol upgrades, Fusaka and Glamsterdam. The gas limit on Ethereum has been raised to 37.3 million.

Core Ethereum developers have tentatively set the dates for the forthcoming protocol upgrades — the Fusaka hard fork, which encompasses 11 Ethereum Improvement Proposals (EIP) currently undergoing testing, along with the Glamsterdam hard fork.

As reported by ethPandaOps, the Fusaka devnet is scheduled to launch on July 23, 2025. Fusaka represents the next significant upgrade to the Ethereum network following the Pectra hard fork that took place in May. A public testnet is anticipated for September and October, with the mainnet upgrade planned for between November 5 and 12.

Notable EIPs included in the Fusaka hard fork:

• EIP-7594. Enables nodes to execute selective data availability sampling, minimizing the necessity to fully download data and enhancing network resilience.
• EIP-7823. Restricts input parameters for the precompile MODEXP to mitigate DDoS threats and prepares for a potential migration of functionality into the Ethereum Virtual Machine (EVM).
• EIP-7825. Establishes a gas limit of 30 million per transaction, balancing the flexibility of intricate operations with safeguards against excessive costs.
• EIP-7883. Increases the base cost of MODEXP and modifies fees to thwart attacks and enhance fee equity.
• EIP-7892. Incorporates preparatory measures for future Binary Large Objects (BLOB) upgrades.
• EIP-7917. Offers a deterministic algorithm for pre-selecting the proposer device, enhancing predictability and simplifying protocol analysis.
• EIP-7918. Connects gas prices to actual execution costs, preventing discrepancies between BLOB fees and execution expenses.
• EIP-7934. Implements a cap on the maximum size of RLP transaction blocks, streamlining processing and alleviating peak validation pressures.
• EIP-7935. Establishes the default block gas limit.
• EIP-7939. Introduces a new opcode to the EVM for counting leading zeros in a word, enhancing the efficiency of specific cryptographic and mathematical computations.
• EIP-7951. Provides native support for the secp256r1 elliptic curve, broadening cryptographic capabilities and enhancing user experience for applications.
• EIP-7642. Eliminates deprecated fields that were utilized prior to the transition to Proof of Stake.

Simultaneously, developers are preparing for the subsequent major network upgrade — Glamsterdam. Key EIPs for this hard fork will be finalized in July, with certification set to be frozen on August 1. Proposals for inclusion in the fork will be accepted until August 21. Priorities include EIP-7732 and EIP-7805, which focus on enhancing network resilience and user experience.

In the meantime, data from Etherscan indicates that the Ethereum network gas limit increased by 3% over the past weekend, rising from 36 million to 37.3 million. Network throughput, according to Chainspect, increased from 15 to 18 transactions per second. This growth is attributed to validator activity. GasLimits data reveals that approximately half of the network’s validators support a further increase of the gas limit to 45 million, which could potentially lower mainnet fees by 15–33%.

Last year, Ethereum Co-Founder Vitalik Buterin suggested raising the gas limit to 40 million. This year, Vitalik is advocating for a significant simplification of the blockchain’s core layer architecture, which includes optimizing the consensus and execution layers, transitioning to a new virtual machine, and standardizing essential components.
