Anza researchers propose SIMD-0675 to use Solana validators’ locations for consecutive nearby block production, cutting handover delays under Alpenglow

Anza's Head of Research, identified as @TheWattenhofer, and Quentin Kniep have proposed SIMD-0675, which would use validators' self-reported geographic locations to schedule nearby validators consecutively for block production under Alpenglow. The proposal is intended to reduce delays between block producers without altering each validator's allocation of turns. According to the text, simulations reduced average handover latency between honest validators by 53%, from 36.2 ms to 17 ms.
