Ethereum block gas limit raised to 45 million

The block gas limit of the Ethereum blockchain has been raised to 45 million units, a 25% increase from the previously set 36 million units in February 2025. The gas limit officially takes effect at block number 22968004. The increase to 45 million is part of Ethereum's expansion roadmap, with the validator's short-term goal being a 60 million gas limit and the long-term plan to achieve a 15 million gas limit through the upcoming Fusaka hard fork and EIP-7935. To reduce risks, developers have also introduced protection mechanisms such as EIP-7983, setting the upper limit of gas usage for a single transaction at 16.77 million units to prevent denial of service attacks and ensure network stability.
