Ethereum developers are considering significant changes to the network's gas limit and cost structure for 2026. A potential scenario includes a fivefold increase in the gas limit, accompanied by a corresponding rise in gas costs for operations deemed inefficient. Targeted adjustments may affect SSTORE operations, particularly when creating new storage, and precompiles, excluding elliptic curve operations. Additionally, contracts with large sizes and certain complex arithmetic opcodes, such as MODMUL, may see increased costs. These changes aim to optimize network efficiency and resource allocation.
