Solana Geo-Aware Leader Schedule: Balancing STAKE_FLOOR and RUN_LENGTH

Researchers have examined the two key parameters of Solana’s geo‑aware leader schedule—σ (STAKE_FLOOR) and γ (RUN_LENGTH)—to strike a balance between reducing transaction handoff latency and maintaining network security. The study highlights how a lower STAKE_FLOOR can accelerate handoffs by allowing more leaders to participate, but it also increases the risk of malicious actors gaining influence. Conversely, a higher RUN_LENGTH reduces the frequency of leader changes, which can improve security but may lead to higher latency for transaction propagation. The analysis suggests optimal values depend on network conditions and threat models, recommending a moderate STAKE_FLOOR combined with a carefully tuned RUN_LENGTH to achieve both performance and resilience. This work provides a framework for operators to adjust these parameters in response to evolving network dynamics and security considerations.
