Ethereum is planning two hard forks in 2026, potentially increasing the L1 gas limit to 200 million.

According to Odaily Planet Daily, Ethereum plans two hard forks in 2026: Glamsterdam and Heze-Bogota. The Glamsterdam hard fork is expected to take place in mid-2026, with key features including the Block Access List (EIP-7928) and the Native Proposer Builder Separation (ePBS). EIP-7928 will enable parallel block processing, transforming Ethereum from single-threaded to multi-threaded processing, improving throughput and addressing disk read bottlenecks. ePBS integrates block building and proposal processes into the consensus layer, aiming to reduce the risk of MEV centralization and provide validators with more time to verify ZK proofs.

Regarding scalability, Ethereum's L1 gas limit is expected to increase significantly in 2026. Besu client engineer Gary Schulte predicts the gas limit will soon reach 100 million, while Ethereum Foundation co-director Tomasz Stańczak predicts it could double to 200 million after the implementation of ePBS, or even reach 300 million by the end of the year. Furthermore, the number of data blobs may increase to 72 or more per block to support L2 processing hundreds of thousands of transactions per second. The Heze-Bogota fork at the end of 2026 will introduce the Fork Selected Include List (FOCIL), designed to enhance the network's censorship resistance by forcing the inclusion of specific transactions.
