Ethereum developers are advancing plans for the network’s next major upgrade, Fusaka, which is tentatively scheduled for a mainnet launch in early November. The Fusaka hard fork is designed to improve network scalability and security, continuing Ethereum’s broader mission to enhance performance and decentralization.
The next developer testnet for Fusaka is expected to go live this week, with public testnets lined up for September and October. The upgrade will include 11 Ethereum Improvement Proposals (EIPs), among them EIP-7825, which focuses on bolstering the network’s resistance to malicious activity while improving scalability.
Originally included in the proposal list, EIP-7907—intended to expand contract code size limits and introduce gas metering—has been removed to streamline testing efforts. The controversial EVM Object Format upgrade was also excluded, according to Ethereum core developers.
The Fusaka timeline places it approximately six months after Ethereum’s previous hard fork, Pectra, which delivered key changes like account abstraction and validator staking enhancements. Developers continue to prioritize shorter upgrade cycles in response to community demand for faster innovation.

In parallel, planning is already underway for Ethereum’s subsequent upgrade, Glamsterdam. Developers are expected to finalize which features will be included during the next AllCoreDevs Execution call on August 1. One proposal under discussion includes reducing Ethereum’s block time from 12 seconds to six—an initiative aimed at boosting transaction throughput and improving DeFi application performance. If approved, this change will be introduced with Glamsterdam, anticipated to launch in 2026.
Meanwhile, Ethereum validators have expressed strong support for increasing the network’s gas limit to 45 million. This move is expected to lower transaction fees and enhance overall scalability. Ethereum co-founder Vitalik Buterin noted that approximately half of staked ETH is already backing the gas limit proposal.
With Fusaka nearing its final development stages and Glamsterdam on the horizon, Ethereum’s evolution continues to accelerate, driven by both technical innovation and community engagement.
