How It Works

Every valuable item gets a unique fingerprint based on its NBT data. When players move items around, the plugin
tracks these fingerprints and catches duplicates before they spread.

Detection Methods

• Velocity Tracking: Catches items appearing too fast
• Cluster Detection: Spots identical items in groups
• Cross Validation: Verifies item movements match expected behavior
• Packet Analysis: Detects client manipulation attempts
• Pattern Recognition: Identifies macro and bot patterns
