Ethereum co-founder Vitalik Buterin celebrated a significant scaling achievement for the network after it reached a new record of 3,453 transactions per second (TPS). The milestone underscores the growing capacity of the Ethereum ecosystem, driven largely by advancements in scaling technologies.

Scaling Beyond the Mainnet

This new record is a massive leap from the Ethereum mainnet’s typical performance, which usually handles between 15 and 30 TPS under normal conditions. The substantial increase in throughput is made possible by the combined processing power of Layer-2 rollups, including prominent solutions like Arbitrum, Optimism, Base, and zkSync.

Historically, Ethereum’s limited throughput on its main Layer-1 network has led to congestion and high fees during periods of heavy demand. The network’s current strategy directly addresses this bottleneck through a multi-faceted approach involving Layer-2s and other technical improvements.

Buterin’s Continued Focus on Scalability

Buterin has long identified scalability as a critical challenge for the blockchain. In recent comments, he praised the scaling solution zkSync Atlas as an “underrated and valuable” technology while emphasizing that “incorruptability” remains a blockchain’s most important quality.

He also recently highlighted a technology known as PeerDAS (peer data availability sampling) as another crucial element for expanding Ethereum’s capabilities. These developments, along with upgrades like proto-danksharding, are part of a broader roadmap to make the network more efficient and accessible for a growing user base.
