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

PANews reported on January 8th that Vitalik Buterin stated in an article on the X platform that increasing bandwidth is more secure and reliable than reducing latency. With PeerDAS and ZKP, Ethereum's scalability can be improved thousands of times without conflicting with decentralization. Latency, on the other hand, is limited by physical laws and real-world environments, such as the need to support global home nodes, censorship resistance, and anonymity. He pointed out that reducing latency to within 2–4 seconds is a reasonable goal, while applications requiring higher real-time performance (such as AI-driven applications) will rely on localized scaling such as L2 and "city chains."
