Ethereum Fusaka Hard Fork Goes Live, Slashing L2 Fees & Boosting Network Capacity

The Ethereum Fusaka hard fork officially went live today, marking one of the most impactful upgrades to the Ethereum ecosystem in recent years. Designed to improve scalability, reduce network costs, and prepare Ethereum for massive Layer-2 expansion, Fusaka brings a set of powerful enhancements that set the stage for the blockchain’s next growth phase.

At the center of this upgrade is PeerDAS, a breakthrough data-availability system that cuts validator bandwidth requirements by nearly 85%. This efficiency boost allows more nodes to participate without heavy hardware demands, strengthening decentralization while improving network performance.

One of the biggest benefits of the Fusaka hard fork is the immediate reduction in fees across major Layer-2 networks. Platforms like Arbitrum, Optimism, and Base are expected to see 40–60% lower transaction fees, making Ethereum-powered applications more affordable for everyday users.

The upgrade also includes a significant increase to Ethereum’s block gas limit—from 36 million to 60 million, representing a 67% rise. This change enables the network to process more transactions per block, helping relieve congestion during peak activity.

With Fusaka, Ethereum moves closer to supporting 100,000+ transactions per second across its Layer-2 ecosystem. This milestone positions Ethereum as one of the most scalable and developer-friendly blockchains in the world.

As adoption of Layer-2 networks accelerates, the Ethereum Fusaka hard fork is expected to play a critical role in improving user experience, lowering costs, and enabling the next wave of decentralized apps, DeFi platforms, and blockchain innovation.
