Vitalik: Ethereum should prioritize increasing bandwidth over pursuing ultra-low latency, with L2s set to play a key role in the long term

PANews reported on January 8 that Vitalik Buterin stated on the X platform that increasing bandwidth is safer and more reliable than reducing latency. With the help of PeerDAS and ZKP, Ethereum scalability can be improved by thousands of times without conflicting with decentralization. Latency, however, is constrained by physical laws and real-world environments, especially if global home nodes, censorship resistance, and anonymity are to be supported. He pointed out that reducing latency to the 2–4 second range is a reasonable goal, while applications requiring higher real-time performance (such as those driven by AI) will rely on L2 and localized scaling solutions like "city chains."
