Vitalik: Ethereum should prioritize increasing bandwidth rather than pursuing extremely low latency, and L2 will play a key role in the long term

Vitalik Buterin posted on the X platform that enhancing bandwidth is safer and more reliable than reducing latency. With the help of PeerDAS and ZKP, Ethereum's scalability can increase by thousands of times, and this does not conflict with decentralization. However, latency is constrained by physical laws and real-world environments, especially when supporting global home nodes, censorship resistance, and anonymity.

He pointed out that reducing latency to a range of 2-4 seconds is a reasonable goal, while applications requiring higher real-time performance (such as AI-driven ones) will rely on L2 and "city chains" for localized scaling.
