Paladium Reveals How Its In-House Anti-Cheat System Nemesis Works

Paladium, a French Minecraft server running since 2015 with over 700,000 registered players, has developed an in-house anti-cheat system called Nemesis rather than relying on third-party solutions. Because Minecraft trusts the client by default, cheaters can exploit this by modifying game files, injecting code, reading memory externally, or even using dedicated hardware to bypass standard detection. Nemesis addresses two core questions: whether a player's actions are physically possible, and whether the player's game client can be trusted — the latter made possible because Paladium operates its own custom launcher. The system follows a block-first philosophy, attempting to neutralise cheats in real time by invalidating movements or shutting down the game, rather than immediately issuing bans. Sanctions are treated as a last resort, reserved for cases where blocking and game closure have both failed.
