Anza's SIMD-0675 would schedule Solana validators by geography
- —SIMD-0675 moved to ready for review on Sept. 30, 2026, while SIMD-0674 remains in draft
- —Simulated mean leader handover latency fell from 36.2 ms to 17.0 ms
- —Each geographic bin is capped at 3 consecutive leaders, with a full regional run lasting about 2.4 seconds
- —Validators that do not register a location would be excluded from block production and voting; stake weights stay unchanged
Why it matters: The proposals are tied to Alpenglow, Solana's upcoming consensus protocol targeting roughly 150 ms finality, where handover delays consume a meaningful share of the latency budget.
