TRX Study evaluates SIMD-0675 geo-aware leader schedule for Solana
A study reported by Solana News evaluates SIMD-0675, a geo-aware leader schedule for Solana that reorders the stake-weighted random schedule so consecutive leaders are geographically close, cutting handoff latency. It states no validator's number of leader windows changes, and tests two parameters, STAKE_FLOOR and RUN_LENGTH, on 6,250 synthetic Monte Carlo networks built on today's 124 validator locations. The study recommends STAKE_FLOOR of about 10% and RUN_LENGTH between 3 and 7, noting about a 29 ms mean gain over random at RUN_LENGTH of 7, while flagging risks of leaders concentrating in

Two parameters are tuned: STAKE_FLOOR, the stake fraction that sets each location's compatibility radius, and RUN_LENGTH, the size of contiguous blocks of compatible leaders. SOL
“Two parameters are tuned: STAKE_FLOOR (σ), the stake fraction that sets each location’s compatibility radius, and RUN_LENGTH (γ), the size of the contiguous blocks of compatible leaders.”

The handoff gain levels off quickly as RUN_LENGTH grows, while risks keep rising: leaders concentrating in one region and validators declaring fake locations. SOL
“The handoff gain levels off quickly as γ grows, while the risks keep rising: leaders concentrating in one region, and validators declaring fake locations.”

The study recommends STAKE_FLOOR of about 10%, the highest value that keeps Asia's bins local, and RUN_LENGTH between 3 and 7, about a 29 ms mean gain over random at RUN_LENGTH of 7. SOL
“The study recommends σ ≈ 10%, the highest value that keeps Asia’s bins local, and γ between 3 and 7 (about 29 ms mean gain over random at γ = 7).”
