Ethereum's Fusaka Hard Fork Sets Stage for Steady Improvement

The Ethereum network has undergone significant changes with the recent Fusaka hard fork. Activated on December 3, 2025, this upgrade lowered node operating costs and reduced settlement latency for layer-2 networks.

This shift is expected to make Ethereum's decentralisation argument stronger, as it becomes more attractive for developers building infrastructure, thus reducing concentration risk and censorship resistance. Additionally, faster and cheaper settlement makes layer-2 networks more economically viable, growing the total addressable market for Ethereum-secured transactions without congesting the base layer.

The Fusaka hard fork has also changed the upgrade narrative from episodic event-driven speculation to a steady compound improvement story. Builders can now plan around a predictable upgrade schedule, and investors have fewer large binary catalyst events creating volatility spikes.
