Ethereum’s Fusaka Upgrade Delivers Performance Boost & Scalability Advancements

Ethereum’s recent Fusaka upgrade has brought about significant improvements to Layer 1 performance, increased data storage capacity, and lowered transaction costs on the network. The upgrade, deployed on December 3, 2025, is aimed at increasing Ethereum’s scalability and efficiency. Key changes include expanding blob capacity by eight times, allowing for cheaper and more efficient off-chain data storage crucial for Layer 2 scaling solutions. This will lead to faster transaction finality and higher network throughput.
