Ethereum will undergo two hard forks in 2026, potentially increasing the gas cap to 200 million.

According to Foresight News , Ethereum plans two major hard forks in 2026: the Glamsterdam fork, expected in the middle of the year, and the Heze-Bogota fork, expected at the end of the year. The core features of the Glamsterdam fork include Block Access Lists (EIP-7928) and native proposer-builder separation (ePBS). Block Access Lists will enable parallel block processing, allowing multiple transactions to be processed simultaneously, thereby increasing throughput without significantly changing hardware requirements.

By 2026, Ethereum's L1 gas cap is expected to increase from the current 60 million to 100 million or even 200 million, and the number of blobs may increase to 72 or more per block, helping L2 process hundreds of thousands of transactions per second. Furthermore, approximately 10% of validators are expected to switch to validating ZK proofs. The Heze-Bogota fork at the end of the year will focus on censorship resistance, planning to introduce Fork-Choice Inclusion Lists (FOCILs), which will authorize multiple validators to enforce the inclusion of specific transactions in blocks, thereby enhancing the network's decentralized nature.
