The Fusaka upgrade, a planned Ethereum hard fork in November 2025, includes 11 EIPs aimed at improving network performance, scalability, and efficiency.
What’s the news
- EIP-7594 (PeerDAS): Reduces node bandwidth and storage load, aiding Layer-2 rollups
- EIP-7825 (Spam Resistance Checks): Shields the network from transaction spam
- Gas Limit Increase: Up to 150 million gas per block for higher transaction throughput
Technical foundation & rollout
- Devnet-3: July 2025
- Public testnets: September – October 2025
- Mainnet activation: Scheduled for early to mid-November 2025
Good to know
- Fusaka is next in the six-month upgrade cycle following Pectra, setting the stage for Glamsterdam in 2026
- Backend improvements will translate into more stable gas fees, higher throughput, and greater network security for users
- Hard Fork: A non-backward-compatible protocol change; Ethereum has already undergone several such hard forks.
