Ethereum has set a new scalability milestone, reaching a record 3,453 transactions per second (TPS) on November 4, 2025. This achievement significantly surpasses the network's typical Layer 1 average of 15-30 TPS. Co-founder Vitalik Buterin celebrated the milestone, noting the importance of zkSync Atlas and PeerDAS technology in overcoming previous network bottlenecks. Layer 2 solutions like Arbitrum and zkSync have already demonstrated the capability to handle hundreds to thousands of TPS, but this new record highlights Ethereum's ongoing efforts to enhance its scalability. Buterin emphasized that zkSync Atlas is 'underestimated but valuable' in the network's scalability strategy.
