Ethereum co-founder Vitalik Buterin has publicly praised the upcoming Fusaka upgrade, calling it one of the network’s most important steps toward long-term scalability and user security. His comments boosted optimism across the Ethereum community as developers finalize the upgrade roadmap.
Buterin highlighted that the Fusaka upgrade introduces significant improvements to transaction efficiency, making Ethereum faster and more affordable during peak network activity. He noted that these enhancements will help reduce congestion while supporting more complex applications on-chain.
According to Buterin, Fusaka moves Ethereum closer to its long-term vision of becoming a highly scalable, globally used settlement network without sacrificing decentralization.
Beyond speed and cost improvements, Buterin emphasized the upgrade’s focus on robust security measures. Fusaka introduces new safeguards for smart contract interactions and better protection for rollups, which now handle a growing share of Ethereum-based activity.
Developers say the update will also make it easier for Layer-2 networks to integrate upgrades, reinforcing Ethereum’s multi-layer ecosystem. Buterin described Fusaka as a “critical foundation” for future enhancements, including data availability improvements and next-generation scaling features.
