Block Extinction
Block Extinction gradually drives chosen blocks toward extinction once they reach a configured condition, and it runs on the server alone.
What it does
Blocks are tracked through a shared remaining count. When a block reaches the extinction condition, the mod removes or prevents it according to the configured extinction mode. Detection works by chunk, and the behavior can be tuned through whitelist management and remaining-count management, so a world can keep certain blocks out of the process.
Only the server needs the mod, so players join without installing it. Block Extinction works in single-player worlds only, with no official LAN world support so far, and the author plans LAN multiplayer for a later release, while noting that the multiplayer sync exists but calls for care when used.
The mod is published for Fabric and needs Fabric API. Its files cover Minecraft 1.21.11, and the latest build, v1.0.1, was released on 2026-08-08. The source code and issue tracker are public, and the code is released under the MIT License.
Key features
Configurable extinction
The extinction behavior, block tracking, whitelist management and remaining-count management can all be adjusted in the configuration.
Chunk-based detection
Affected blocks are found chunk by chunk, so the mod checks the loaded area of the world rather than every block at once.
Management commands
The blockextinction command manages extinction data, the whitelist and other administrative tasks, and permission restrictions block unauthorized changes.
Configuration interface
With Mod Menu installed, the configuration interface can be opened from the mod list.
Stored world data
Settings and world-related data are kept in a blockextinction folder inside the config directory, and deleting that folder removes all stored data.

LAN Whitelist is client and server, open source under the MIT License, and covers 1.20.2 – 1.21.10, so it does not reach 1.21.11.

Autoopen-lan is client-side only, under the Apache License 2.0, and covers 1.18.2 – 1.21.11, so only players install it. Block Extinction is server-side only and open source under the MIT License.
