Ethereum Fusaka Hard Fork is scheduled for November, and Glamsterdam will debut in early 2026.

Ethereum is preparing for two hard forks, Fusaka and Glamsterdam, to accelerate network expansion and test decentralization resilience, which will be the focus of the market for the next 18 months. (Background: Experts predict Ethereum could reach $5000 – a review of 5 potential altcoins) (Context: Ethereum has finalized the "Fusaka upgrade": including EIP-7594 and 13 other items, increasing the block size limit to 16MB) Since the "Merge" transitioned to proof of stake in September 2022, every technological iteration of Ethereum has affected the crypto market and even traditional finance. The developer community has now set two new milestones - according to the latest news, the Fusaka hard fork is expected to go live in November 2025, and Glamsterdam will debut in the first half of 2026. Both upgrades will simultaneously improve efficiency, drop latency, and test the network's ability to maintain decentralization under rapid expansion. Fusaka: Accelerating the first shot Fusaka is only six months away from the last Pectra upgrade, showing the community's consensus on the "update cycle." The core proposal EIP-7825 enhances network resilience by adjusting the transaction Gas limit, along with EIP-7594's data availability sampling and EIP-7951's optimization of cryptographic operations, which is expected to improve both bandwidth and security. To accelerate performance, Fusaka also plans to raise the L1 Gas Limit to 45 million. However, larger blocks mean nodes need to bear higher hardware and bandwidth costs, and the temporarily removed EIP-7907 illustrates the developers' trade-off between time and complexity. Glamsterdam: Halving block time, aiming for real-time experience If Fusaka emphasizes "amplifying traffic," Glamsterdam focuses on "shortening time." The core EIP-7782 reduces block time from 12 seconds to 6 seconds, anticipating halving transaction latency, which is crucial for DeFi trades, blockchain games, and high-frequency strategies. Coupled with EIP-7928's block-level access list, nodes can manage data more efficiently, reducing bandwidth consumption. Core developers have scheduled to confirm the upgrade scope in early August 2025, providing the market with a clear timeline and reducing the risk of fluctuating specifications. Gas Limit increase: The tug-of-war between efficiency and decentralization For users, a higher Gas Limit means lower fees and greater computational space; for nodes, it directly escalates hardware expenditure and synchronization pressure. Currently, about 50% of stakers support raising the limit, and the client Geth v1.16.0 continues to optimize network efficiency. Vitalik Buterin also reminded developers that users and stakers must find a balance between "efficiency dividends" and "node clearance," otherwise decentralization could become the biggest concern of the upgrade.
