$ETH , the world’s second-largest blockchain network and the backbone of decentralized finance (DeFi), has just taken another major step in its development with a big upgrade called Fusaka — rolled out on December 3, 2025. CCN.com
🚀 What Is the Fusaka Upgrade?
Fusaka is the next major protocol update (hard fork) for Ethereum — part of a long-term plan to make the network faster, cheaper and more scalable. It builds on earlier upgrades like Pectra that already improved Ethereum. CCN.com
The core goal of Fusaka is simple:
👉 Make Ethereum more efficient for users, developers, and large decentralized apps (dApps). CCN.com
📌 Key Changes and Features
🧩 1. PeerDAS — Better Data Handling
Fusaka introduces a new system called Peer Data Availability Sampling (PeerDAS). Instead of validators downloading all blockchain data, they verify small pieces. This means:
Nodes need less bandwidth
Data is easier to share across the network
More transactions can be processed
👥 This improves Layer-2 scaling, which is crucial for apps built on top of Ethereum. CCN.com
🟩 2. Higher Capacity for Layer-2
The upgrade increases support for Layer-2 networks (like Arbitrum, Optimism) — allowing them to handle much more data and lower fees. This means apps become cheaper and faster to use. CCN.com
⛽ 3. Gas Limit Boost
Fusaka increases the block gas limit (the amount of computation each block can handle). This leads to:
Faster transaction processing
Lower congestion during peak usage
Better performance for smart contracts
💡 It’s a major step toward scaling Ethereum without changing its core security model. CCN.com
📉 Why This Update Matters
🔹 Cheaper Transactions
Fusaka makes it cheaper to move ETH and use dApps — highly important for everyday users and developers. Analysts say transaction costs could fall significantly once Layer-2 usage ramps up. AInvest
⚡ Faster Network
With better data processing and higher throughput, Ethereum can handle more transactions — boosting usability for big DeFi platforms, NFT marketplaces, and Web3 apps. AInvest
📈 Effects on Price & User Confidence
While Ethereum’s price is influenced by many factors, upgrades like Fusaka improve fundamental network strength — which often drives long-term interest from investors, developers, and institutions. Investing.com India
🧩 Looking Ahead
Ethereum’s development doesn’t stop here. After Fusaka:
Developers are planning additional upgrades in 2026 — like Glamsterdam and Hegota — for deeper improvements in scalability and performance. BTCC
More emphasis is being placed on ZK-EVMs and distributed block building to further enhance speed and decentralization. BTCC
These upgrades are part of Ethereum’s long roadmap toward wider adoption and stronger infrastructure — making it an even more powerful platform for global Web3 and DeFi innovation.
