Vitalik Buterin, co-founder of Ethereum, stated that a significant proportion of validators with staked ETH, who operate the blockchain, have signaled their intention to increase the gas limit, thereby enabling higher transaction volumes on the network. According to the gaslimit.pics dashboard, as of July 21, 2025, 49% of validators' staked ETH have indicated their approval for increasing the gas limit to 45 million units. On the Ethereum blockchain, gas serves as the unit of measurement for the computational effort required to execute transactions or smart contracts. Whenever users interact with the blockchain, they must pay a gas fee, which covers the cost of utilizing Ethereum's computational resources, ensuring that users pay in proportion to the complexity of their actions.
Each Ethereum block has a gas limit, representing the maximum amount of gas that can be consumed by all transactions in that block. If the total gas required by pending transactions exceeds the block's limit, some transactions are postponed to future blocks. Due to limited space, transactions compete for inclusion, with those offering higher fees being more likely to be included first.
The proposed increase in the gas limit to 45 million units comes as Ethereum's native token, ETH, has broken through $3800 over the weekend, with large institutions deploying capital to utilize the blockchain for infrastructure and other financial applications. The gas limit was previously increased in February, when it was set to 36 million, marking the first increase since 2021, after more than half of the network's validators supported the change without requiring a hard fork. While Ethereum core developers aim to scale the blockchain to accommodate more transactions, they do not plan to stop at this limit.
According to Parithosh Jayanthi, a DevOps Engineer at the Ethereum Foundation, 'We're targeting 45 million for now, with plans for higher limits soon after. There are significant developments planned for the next few years.'
