Percentile Contest Rating Engine
EloNode
Every rating converges. No match left unranked.
An ultra-low latency distributed rating computation service utilizing an optimized Glicko-2 and TrueSkill variation, evaluating multi-contestant leaderboards and tournament brackets with sub-millisecond convergence guarantees.
Multi-contestant rating convergence
Traditional Elo models fall apart in free-for-all matches. EloNode extends Glicko-2 volatility parameters across multi-participant rounds, updating skill ratings and standard deviations in a single atomic pass.
Atomic rating transactions & Redis Lua
Rating adjustments require strict linearizability. EloNode executes leaderboard computations inside atomic Redis Lua scripts with zero lock contention across millions of competitive players.
Event-driven tournament orchestration
Match completions emit structured events via Apache Kafka, allowing asynchronous bracket reconciliation, tier promotion calculations, and real-time WebSocket leaderboard broadcasts.
Statistical drift & cheat resilience
EloNode models player uncertainty dynamically. Inactive accounts experience Bayesian rating inflation decay, while sudden performance spikes trigger anomaly detection alerts.
