[Vitalik: Ethereum Should Prioritize Increasing Bandwidth Over Pursuing Ultra-Low Latency, L2 Will Play a Key Role in the Long Term] Vitalik Buterin posted on the X platform that 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 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 localized expansions like 'city chains.'
