[Vitalik: Ethereum should prioritize increasing bandwidth over pursuing ultra-low latency, and L2 will play a key role in the long term] Foresight News reports that Vitalik Buterin tweeted, 'Increasing bandwidth is safer and more reliable compared to reducing latency. With the help of PeerDAS and ZKP, Ethereum's scalability can be improved by thousands of times without conflicting with decentralization. Latency, however, is constrained by physical laws and real-world conditions, especially if we aim to support global home nodes, censorship resistance, and anonymity. I believe reducing latency to the 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 localized scaling solutions like "city chains."'
