Ethereum News Today: Ethereum's November 2025 Fusaka Fork to Raise Gas Limit to 150M via 11 EIPs for Scalability

Ethereum’s Fusaka hard fork, set for activation in early November 2025, represents a strategic step in the network’s ongoing evolution, prioritizing backend optimizations over user-facing features. The upgrade, which will implement 11 Ethereum Improvement Proposals (EIPs), aims to enhance scalability, security, and gas efficiency while maintaining compatibility with existing smart contracts. Unlike previous forks such as Pectra, which introduced innovations like account abstraction, Fusaka focuses on refining core protocol parameters to support growing demand without disrupting user experiences [1].

A key change in Fusaka is the increase of the block gas limit to 150 million units, allowing each block to process more transactions and potentially reducing fees during peak demand. However, this adjustment comes with trade-offs, including slower block propagation and increased data storage requirements. EIP-7825 is another critical inclusion, designed to protect nodes from spam attacks by introducing checks that strengthen network resilience. Meanwhile, the proposed EIP-7907, which aimed to double the contract code size limit and introduce new gas metering rules, was deferred to avoid testing delays, with potential for future implementation [1].

The timeline for Fusaka follows Ethereum’s accelerated six-month upgrade cycle. A developer-only Devnet launched in mid-July 2025, followed by public testnets in September and October 2025 to facilitate community testing. The mainnet activation is contingent on successful testnet validation and alignment with the Ethereum team’s target to deploy the fork before the Devconnect conference in Buenos Aires (November 17-22, 2025). This schedule reflects the project’s emphasis on timely execution, with community members like protocol support member Nixo advocating for strict adherence to the timeline to ensure smooth integration [1].

Fusaka’s approach underscores Ethereum’s philosophy of incremental improvements. By avoiding disruptive code rewrites, the upgrade minimizes risks for developers and users while addressing foundational challenges such as transaction throughput and network robustness. These changes are expected to support Ethereum’s competitiveness with faster layer-2 solutions and other blockchains, particularly as decentralized finance (DeFi) applications and interactive use cases demand higher capacity [1]. Analysts note that such iterative upgrades are essential for maintaining the network’s reliability and adaptability, balancing innovation with stability in a rapidly evolving ecosystem [2].

The absence of user-facing features in Fusaka aligns with Ethereum’s broader strategy of prioritizing infrastructure over visible changes. While the upgrade will not alter smart contract behavior or introduce new functionalities, its backend optimizations are crucial for sustaining long-term growth. This approach has been well-received by the community, with discussions on platforms like Reddit highlighting the importance of regular protocol maintenance to ensure Ethereum’s resilience amid increasing adoption [2].

As the November 2025 deadline approaches, the focus remains on seamless execution. Developers will monitor testnet results and finalize the activation block height to ensure all nodes upgrade simultaneously. By reinforcing its technical foundation, Fusaka positions Ethereum to handle future demands while adhering to its commitment to continuous improvement [1].
