Alive | Advanced Block Decay
Alive | Advanced Block Decay adds a world-wide decay system in which unsupported and unused blocks slowly break down over time, with the rate depending on depth and nearby activity.
What it does
Decay chains define which solid blocks break down and what they turn into, from stone and wood down to basic dirt and grass. Each block can randomly decay according to its chain, and the chance rises for blocks nearer the ground surface, while deeper blocks decay more slowly. Structures with no players, villagers or pillagers nearby slowly collapse until little remains, whereas blocks close to human entities last longer. The end dimension is excluded.
The server and every player need the mod installed. It is published for Fabric, Forge and NeoForge across 21 release versions, 1.19.4 – 26.3, and the author describes it as a work in progress with possible issues on ported worlds, so backups are advised. It belongs to the Alive Modding Ecosystem, and the author recommends pairing it with Alive Dynamic Dirt Physics and Alive Dynamic Ecosystems.
Key features
Chain-based block decay
Solid blocks decay along configurable decay chains, so each material breaks down into a defined successor over time.
Depth and surface weighting
Blocks near the surface decay faster than those underground, which slows decay the deeper a block lies.
Human-proximity protection
Blocks near players, villagers and pillagers remain longer, so inhabited areas hold their shape while abandoned structures fall apart.
Viewable decay chains
The default decay chains are published as a script and a flow chart representation, so server owners can inspect what each block turns into.

How it compares
Wart Decay is a server-side only decay mod for 1.20 – 1.20.1 under All rights reserved, with Fabric, Forge, NeoForge and Quilt builds. Fast Leaf Decay is a Fabric-only server-side mod for 1.19 – 1.19.2 under the GNU Lesser General Public License v3.0 only, and it targets leaves rather than the whole world. Bring Decay is open source under the GNU General Public License v3.0 or later, works on client and server, and covers Fabric and Quilt for 1.16.3 – 1.20.4. Alive is not open source, so its code cannot be reused under those licenses.
