New and improved Version ==> PointZero

Fragments Anticheat

A server-side anti-cheat system for Fabric that ensures all players are using only allowed mods with correct versions.

✨ Features

• 🔒 Mod verification: Automatically checks all client mods against a server whitelist
• ⚡ Hash-based validation: Uses SHA-256 hashes to guarantee mod integrity
• 📦 Resource Pack Support: Also checks active resource packs
• 👮 OP Bypass: Server operators can use all mods
• 🚀 Performance-optimized: Hashes are cached at startup - no delays when connecting
• 🛡️ Robust: Automatic timeouts and comprehensive error handling

🎮 For players

When you join the server, your installed mods are automatically checked. If you are using unauthorized or modified mods, you will be kicked with a list of problematic mods.
