Minecraft 1.21.1, 1.21용 Anti-Dupe 플러그인

Anti-Dupe 3.7

Anti-Dupe combines real-time transaction verification, persistent item accounting, signed unique-item identities, cross-inventory scanning, automatic quarantine, and safe administrator recovery.

🔍 Know Who, What, When & Where

Anti-Dupe greatly expands what happens after a dupe is detected.

Every new incident can record:

• Who was involved
• What items were duplicated
• When the incident occurred
• Where it happened, including world and precise coordinates
• Backend server information
• Nearby players within 32 blocks
• UUIDs, distance, and optional game mode
• Previous incident relationships and repeat nearby appearances

This gives administrators much more than a simple "dupe detected" warning.

🧩 Chunk Audit

When an incident occurs, Anti-Dupe can automatically investigate the surrounding area.

A fixed 3×3 chunk area is audited — the offender's chunk plus all eight neighbouring chunks.

The audit records:

• Redstone
• Mechanisms
• Storage blocks
• Exact coordinates
• Block totals

This can help administrators identify machines, storage systems, or environmental conditions associated with a duplication exploit.

💻 Command Audit

Anti-Dupe preserves the offender's last 10 player-issued commands when an incident begins.

Commands are displayed:

• Newest first
• With timestamps
• With allowed/cancelled state
• With sensitive authentication information automatically redacted

Passwords, PINs, OTPs, tokens, and authentication arguments are automatically redacted from incident command history.

📦 Easy Incident Recovery

Open the recovery system with:

/antidupe recovery

The recovery GUI provides a simple workflow:

Players ↓ Incidents ↓ Incident Items ↓ Restore One / Restore All

Administrators can inspect confiscated items, browse individual incidents, restore specific items, or restore an entire incident.

⚡ Performance Optimized

Anti-Dupe spreads expensive operations across multiple ticks instead of performing everything at once.

Performance and lag-reduction measures include:

• One chunk per tick incident auditing
• Staggered scheduled scans
• Configurable scan batching
• Delayed chunk verification
• Two-stage detection and confirmation
• Bounded 3×3 forensic scans
• Command history limited to 10 entries
• Asynchronous Discord notifications
• High-speed movement and Elytra stabilization

The goal is strong detection and detailed forensic evidence without unnecessarily impacting server TPS.

🌍 Per-World Enforcement

Every world can independently use disabled, audit, quarantine, or inherit the global mode.

World policies now cover:

• Live inventory transactions
• Delayed confirmation checks
• Player inventories and Ender Chests
• Loaded storage containers
• Signed item identities
• Cross-inventory UUID scanning

This makes temporary-kit PvP arenas and minigame worlds easy to isolate while maintaining full protection in survival worlds.
