Solana’s Next Latency Idea Has a Geographic Trade-Off Validators Cannot Ignore

TL;DR: Research into a geo-aware leader schedule suggests quicker validator handovers, but also warns that grouping leaders by location introduces security trade-offs.
Solana’s push for lower latency is moving beyond shorter slots. A new study of SIMD-0675 considers rearranging its validator leader schedule so that consecutive leaders are more likely to be geographically close, reducing the time it takes information to travel between them.
This is not a proposal to give particular validators m
