Ethereum developers discussed raising the block gas limit from 60 million gas to 75 million to 80 million gas at an all-core developer meeting. Nethermind developer Ben Adams said he is confident in implementing this increase following the second BLOB parameters only (BPO) fork scheduled for January.
Increasing gas limits requires two client-level optimizations before deployment. On the execution layer side, partial BLOB responses require implementation through the engine_getblobsv3 method. On the consensus layer side, the max blob flag should be integrated throughout the client software.
Get your client team ready for January
Ethereum Foundation Developer Operations Engineer Barnabas Busa has requested that all execution layer client teams include partial BLOB responses in the next stable release. The Consensus Layer team has received similar instructions to implement the Max BLOB flag in future versions.
Nethermind developer Kamil Chodola expressed optimism that client teams will be ready to move forward with increasing block gas limits in January. This follows additional testing and activation of the second BPO fork scheduled for this week.
The second blob parameter-only fork will be activated on mainnet on Wednesday, January 7th. This upgrade provides an additional 66% capacity increase for blobs, following the initial BPO fork which delivered a 66% capacity boost when activated on December 9th.
Chodola highlighted ongoing benchmarking work to reprice various opcodes planned for the Glamsterdam fork. He said further testing is needed before finalizing re-pricing numbers. Maria Silva, a researcher at the Ethereum Foundation’s Robust Incentives Group (RIG), offered to convene an additional subcommittee session in the new year to support opcode repricing efforts.
Ethereum network scaling strategy
The gas limit increase is part of Ethereum’s Layer 1 scaling strategy to increase network throughput. Increasing the gas limit increases transactions per block and increases the throughput of the network without requiring changes to the underlying protocol.
The developers have agreed to cancel ACD calls for the next two weeks, from December 22nd to January 1st, as part of the holiday period. The team will reconvene on Monday, January 5th to make up the all-core developer execution meeting, and will resume regular twice-weekly meetings starting the same week.
This timeline will help Ethereum improve its performance in early 2026. Client teams will have several weeks to complete the necessary optimizations before the activation of the BPO2 fork on January 7th, when adjustments to gas limits will be possible.
