Why cheating is hard to stop
The client runs on hardware the player controls, so it can be inspected and modified. Anti cheat is a layered defense, not a single switch, because no one layer is complete.
The layers
- Server authority is the foundation. The server validates every action, so impossible moves like teleporting are simply rejected.
- Input sanity checks flag superhuman aim or movement that violates physics constraints.
- Statistical detection mines telemetry for outliers, like accuracy far beyond the human distribution.
- Client integrity tools detect tampered binaries or known cheat signatures, an arms race with cheat authors.
Server side wins
- Pairing authority with interest management means clients never receive data about unseen enemies, defeating wallhacks at the source.
- Aimbots are caught by analyzing the distribution of a player's aim over many matches, not a single shot.
- Detections feed a review and ban pipeline rather than instant kicks, to limit false positives.
Key idea
Anti cheat layers server authority, scoped data, and statistical telemetry analysis, since the untrusted client can always be tampered with.
