Hey! You’ve probably heard that Ethereum is preparing a new upgrade—Fusaka, set to launch in November 2025. But what exactly is it, and how will it affect the network? Let’s break it down together.
What Is Fusaka?
Fusaka is an Ethereum hard fork following the Pectra upgrade from May 2025. While Pectra introduced noticeable changes (like account abstraction and higher staking limits), Fusaka works "under the hood"—improving scalability, network efficiency, and node resilience without touching smart contracts.
When Is It Happening?
Devnet-3 (a testnet for developers) launched in July 2025.
Public testnets — September-October 2025.
Mainnet activation — scheduled for November 5, 2025, right before the Devconnect conference in Buenos Aires.
What’s Actually Changing?
Fusaka includes 11 Ethereum Improvement Proposals (EIPs). Here are the key ones:
🔹 EIP-7594 (PeerDAS) – Nodes no longer need to download full block data, reducing load and improving performance.
🔹 EIP-7825 – Protection against spam transactions to prevent network congestion.
🔹 EIP-7935 – Gas limit increase from ~45M to 150M, allowing more transactions per block.
🔹 EIP-7951 – Support for secp256r1 cryptography (a Web2 standard used by Apple Pay and Google Pay).
You can check out the full list here, but the bottom line is: these changes make Ethereum faster, more stable, and cheaper to use.
How Will This Affect Users?
For regular users: Gas fees will stabilize, especially during peak demand.
For developers: DApps won’t need code changes but will run more efficiently.
For validators: Node load decreases, but hardware requirements may increase.
What’s Next?
After Fusaka, Ethereum is already working on the next upgrade—Glamsterdam (2026), which could reduce block time from 12 to 6 seconds (doubling network speed!).
Final Thoughts
Fusaka isn’t a revolution but an evolution: Ethereum is becoming faster and more reliable without drastic changes. The key takeaway? The network keeps scaling while staying decentralized.
What do you think—are these "technical" upgrades really important, or does Ethereum need something more radical?
