Ethereum's Buterin Reacts to New TPS Record
Ethereum co-founder Vitalik Buterin celebrated the network's new scaling milestone as Ethereum reached a record of 3,453 transactions per second (TPS) on November 4, 2025. Typically, Ethereum processes 15–30 TPS on its mainnet (Layer 1), but with Layer 2 rollups like Arbitrum, Optimism, Base, and zkSync, the network can handle hundreds to thousands of TPS. Buterin also praised zkSync Atlas and highlighted technologies like PeerDAS as crucial for further scalability improvements, addressing a key bottleneck for Ethereum.

New Record in Transactions Per Second (TPS)
On November 4, 2025, the Ethereum network hit a new transaction per second (TPS) record of 3,453 TPS at 14:37 UTC. This is a significant leap compared to Ethereum's typical average speed of 15–30 TPS on the mainnet (Layer 1) under normal network conditions.
Layer 2 Contributions to Ethereum's Scalability
With the inclusion of Layer 2 rollups such as Arbitrum, Optimism, Base, and zkSync, the combined Ethereum network can process hundreds to a few thousand TPS in total. These scaling solutions play a pivotal role in improving Ethereum's transaction throughput.
Impact of zkSync and PeerDAS on Scaling
Vitalik Buterin recently praised zkSync Atlas, describing it as "underrated and valuable." Furthermore, he emphasized the importance of the PeerDAS technology (peer data availability sampling), which he considers crucial for effectively scaling the Ethereum network.
Scalability: Ethereum's Long-term Bottleneck
In earlier statements, Buterin has identified scalability as a substantial bottleneck for Ethereum, the second-largest blockchain in the world. However, with recent advancements like zkSync and PeerDAS, Ethereum is steadily overcoming these limitations, ensuring its growth and sustainability.
