Study evaluates geo-aware leader schedule proposal for Solana
A Solana study evaluates SIMD-0675, a proposal that reorders the stake-weighted leader schedule so consecutive leaders are geographically close, aiming to cut handoff latency. The study says no validator's number of leader windows changes, and reports tests on 6,250 synthetic Monte Carlo networks built on today's 124 validator locations.

News evidence score: 70/100 from 1 publisher group(s) (Solana 官方新闻); this measures source completeness, not truth or causation.
After site detection, observed returns were 1 hour: -0.32% (difference from BTC -0.05 pp; 20/10/2026, 13:25 → 20/10/2026, 14:29, UTC+8; OKX · USDT). Unlisted windows are unavailable.
In the preceding 30 days, the 99th percentile of absolute hourly returns was 2.01% (OKX · USDT; cutoff 20/10/2026, 13:23, UTC+8). This hourly baseline is not directly comparable with a minute move.

Claims and open questions
What sources claim
- The study evaluates SIMD-0675, which reorders the stake-weighted random schedule so consecutive leaders are geographically close and handoff latency is reduced.
- No validator's number of leader windows changes under the proposal; two parameters, STAKE_FLOOR and RUN_LENGTH, are tuned.
- The parameters were tested on 6,250 synthetic Monte Carlo networks built on today's 124 validator locations, and the handoff gain levels off quickly as RUN_LENGTH grows.
Still unresolved
- The excerpt is truncated; the stated risks tied to growing RUN_LENGTH are not fully reported, and the full SIMD-0675 document or an official status update would confirm them.
- Whether SIMD-0675 has been accepted, activated, or implemented on mainnet is not stated; a governance record or client release note would confirm its status.
- The size of the handoff latency reduction in real network conditions is not quantified beyond the synthetic tests; production telemetry or on-chain timing data would confirm it.
