What do people build with it?

USE CASE 1

Protect a public Minecraft server from players who try to crash it with lag machines.

USE CASE 2

Prevent rival factions from sabotaging events by crashing the server at key moments.

USE CASE 3

Add a safety layer to any Minecraft server where you don't fully trust all players.

USE CASE 4

Keep server stability intact when players build heavy redstone contraptions in a single area.

You need to compile the plugin yourself using Maven before installing it on a Minecraft server.

No license information is provided in the README, so usage rights are unclear.

So what is it?

ChunkFreezer is a plugin for Minecraft servers that stops players from building "crash machines", contraptions designed to overload the server and kick everyone off. Minecraft runs on a central server that processes every chunk of the game world. A chunk is a 16-by-16 block area. When players create certain combinations of blocks and redstone (the game's wiring system), they can generate so much activity in a single chunk that the server can't keep up. The result is lag or a full crash for everyone playing on that server. Server administrators install this plugin to prevent that scenario. If you run a Minecraft server, especially one open to the public or with players you don't fully trust, this gives you a layer of protection against griefing. A griefing example would be a player intentionally building a contraption that crashes the server right before a rival faction's big event. The README doesn't go into detail on exactly which crash machines it detects or what method it uses to neutralize them. It only covers the basics: the plugin is written in Java, like most Minecraft server plugins, and you compile it yourself using Maven, a standard build tool for Java projects.
