Fusaka upgrade advances Ethereum scalability and strengthens network efficiency
Ethereum launches the Fusaka upgrade, marking an important step toward increasing network throughput and maintaining consistently low fees in the long term.
Ethereum, the world’s largest smart contract blockchain with over $73 billion in total value locked (TVL) and processing 1.3–1.8 million transactions per day, has launched the Fusaka upgrade to enable higher transaction capacity while prioritizing security and decentralization.
A key element of Fusaka is EIP-7594 PeerDAS (Peer Data Availability Sampling) — a system that allows Ethereum nodes to verify the completeness of block data without fully downloading it.
“This makes Ethereum more scalable without sacrificing decentralization. That’s the whole point,” said Jason Chaskin, Head of Application Relations at the Ethereum Foundation, in a comment to The Defiant.
According to him, “this path required nearly a decade of research and development, but it now makes it possible to avoid redirecting all users to data centers.”
Fusaka also increases the Layer 1 (L1) gas limit from 45 million to 60 million and introduces the R1 signature precompile, simplifying and reducing the cost of using passkeys in Ethereum applications. For Layer 2 (L2) networks, where fees are already very low, Fusaka helps ensure they remain at that level.
“PeerDAS gives rollups more blob space, and over time that space will only increase… In terms of speed, L2s are already extremely fast. For example, Arbitrum is around 250 ms and Base about 200 ms,” Chaskin noted.
Fusaka is an important step in Ethereum’s plan to process more transactions and prepare for future upgrades. As most activity now occurs on Layer 2 networks such as Base, Optimism, and Arbitrum, reducing data transmission costs plays a key role in keeping fees low and supporting a growing number of users.
In the future, Ethereum plans to gradually increase blob capacity through small forks, once operators and researchers are confident in the system’s safety. Chaskin warned that the rollout will be gradual, as the new software is being deployed for the first time. Nevertheless, Fusaka opens up strong prospects for Ethereum, making it the most predictable environment for development.
