Anti-cheat with trust-based system and 4-layer validation cascade system & packet analysis
PacketEvents Required for 1.21.x
PacketEvents
Note: Plugin can work without it but it may cause problems
NoChance is a anti-cheat with a 4-layer validation cascade system and also with packet-level detection. Designed to catch cheaters while minimizing false positives through trust scoring, adaptive sampling, and statistical analysis.
