InTime: Towards Performance Predictability In Byzantine Fault Tolerant Proof-of-Stake Consensus

Summary: Tackles performance predictability in BFT-PoS by quantifying delays with untimely MEV ratio to expose delay-based reward incentives. Proposes ARI with a CTW to verify arrival times, align rewards with timing, and cut latency variance (max 95.9%). (summarized by gpt-5-nano on Feb 09 2026)
