A new era for Ethereum is on the horizon — meet Fusaka, the upcoming major network upgrade set to launch this December (subject to final testing). Fusaka brings together two powerful components — Fulu (Consensus Layer) and Osaka (Execution Layer) — to deliver one core promise:

A faster, lighter, and more decentralized Ethereum.


Let’s break down what makes Fusaka a game-changer


PeerDAS — Scaling Ethereum for Everyone


The highlight of Fusaka is PeerDAS (Peer Data Availability Sampling) — Ethereum’s new scaling powerhouse.

Instead of downloading every single transaction, validators will sample data to verify large “blobs” from Layer-2 networks like Arbitrum and Optimism.


✅ Higher transaction capacity

✅ Lower L2 gas fees

✅ Faster confirmations


In short: More speed, less cost, and no compromise on decentralization.



Verkle Trees — The Root of a Lighter Ethereum


Goodbye Merkle Patricia Trie, hello Verkle Trees!

This upgrade reduces hardware demands for nodes by shrinking proof sizes — making Ethereum lighter and more accessible.


Imagine running a full Ethereum node on a simple laptop or even a phone!

That’s the future Fusaka is building — Stateless Ethereum and wider decentralization.



History Expiry — Ethereum Cleans Up


Nodes no longer need to store the entire blockchain forever.

With History Expiry, older data safely “expires,” freeing up space and speeding up synchronization.


🪶 Less storage

⚙️ Faster sync times

🌍 Easier solo staking for everyone



EVM Object Format (EOF) — Smarter Smart Contracts


Fusaka refines the Ethereum Virtual Machine with EOF, introducing structured “Sections” for code, data, and metadata.

This means:

• Better security

• Easier audits

• Smoother upgrades


Developers get a cleaner, more modular system — and users get safer, more efficient dApps.



What This Means for You


You don’t have to do anything — but you’ll feel the difference:


Cheaper & faster transactions

More secure smart contracts

Greater decentralization

A stronger, future-proof Ethereum


Fusaka marks Ethereum’s boldest step toward scalability, accessibility, and innovation.

It’s not just an upgrade — it’s the foundation for the next decade of decentralized progress.
