No Danger Player Project (NDP) - Multi-Server Ban System

Project Overview

No Danger Player Project (NDP) is an open-source cross-server ban plugin/mod designed to synchronize ban lists in real-time across multiple servers, preventing malicious players from joining any connected server. By centralizing player ban data, it significantly improves security and management efficiency for server networks.

Core Features

1. ​Real-Time Ban Synchronization

   • When a player is banned on one server, the ban is instantly propagated to all NDP-plugin(mod) has been installed servers.
   • The ip address and playername are bound forcibly to prevent evasion through alt accounts or proxies.

2. ​Multi-Platform Compatibility

   • Stable support for major Java server platforms (Spigot/Bukkit/Folia), with ongoing adaptation for others (see compatibility table below).
   • Future plans include proxy-level coverage (BungeeCord/Velocity).

3. ​Lightweight & High Performance

   • Event-driven asynchronous synchronization minimizes performance impact.
   • Configurable local caching reduces latency for frequent data requests.

4. ​Management Tools

   • Customizable ban reasons, durations, and audit logs.

Supported Server Types

How It Works

Player joins Server A → Plugin checks local/central ban list → If banned, access denied → Syncs ban to Servers B/C/D...

Quick Start

​Installation

• Download the appropriate JAR file to your server's plugins or mods folder.
• Restart server to generate config.yml.

Banning Players

• Command: /ndp <ban/pardon>
• Example: /ndp ban Badplayer test

Roadmap

• Player behavior analysis for automated cheat detection.
