ClaimMod
This is a land claiming mod inspired by Grief Prevention in terms of claiming an area using a claim tool!
About this Mod
ClaimMod — Advanced Land Claiming & Grief Prevention
ClaimMod is a server-side Fabric mod designed to give players and server administrators total control over land protection and grief prevention. Operating entirely server-side, it functions seamlessly for plain vanilla clients while offering a lightweight companion packet API that unlocks advanced, automatic client-side boundary rendering for players running compatible companion client configurations.
Featuring a modular, highly performant spatial indexing engine, tick-accurate accrual math, independent trust matrices, and expansive per-world permission overrides, ClaimMod is built to handle heavy server environments with zero configuration reboots required.

🛠️ Performance Architecture
Unlike old protection mods that loop over massive arrays or suffer from tick-drift, ClaimMod is built from the ground up for modern server performance:
- O(1) Spatial Indexing: Claims are indexed cleanly using a chunk-hashed spatial grid (
worldKey → chunkKey → Set<Claim>). Border checks and interaction lookups run instantly regardless of how many thousands of claims exist on your world. - Real-Time Accrual Processing: Claim block generation checks look at real wall-clock milliseconds (
System.currentTimeMillis()) instead of standard server tick counting. Your players earn points at a perfectly stable rate even when the server drops TPS under heavy entity load.
🔑 Independent Trust Tiers
ClaimMod rejects standard cumulative trust hierarchies. Granting a tier does NOT inherently grant the permissions of any tier beneath it, allowing for fine-grained player delegation:
| Tier | Role Capabilities |
|---|---|
| OWNER | Full building/breaking access, container rights, flag management, claim deletion, and ownership transfers. |
| CO_OWNER | Identical rights to the Owner, except cannot force-delete the claim or transfer primary ownership away. |
| TRUSTED | Full building and block breaking access, along with all standard block/container interactions. |
| FLAGS | Purely grants visibility and toggles for claim flags; cannot build, break, or look inside containers. |
| CONTAINER | Restricts usage strictly to inventories (chests, furnaces, etc.). |
| TRAVELER | Purely restricted to mechanical navigation pathways (standard doors, trapdoors, and fence gates). |

👁️ Border Visualization Matrix
Vanilla client? Companion client? No problem. ClaimMod securely processes visualization vectors for everyone:
- Fake Block Packets (Vanilla-Friendly): Right-clicking with items shifts regional border grids smoothly into view via
ClientboundBlockUpdatePacketarrays. Surfaces are automatically mapped locally without shifting physical world files. - Adaptive Dynamic Palette: Edge color configurations morph cleanly relative to a player's spatial context:
- Owner / Co-Owner: Vibrant Gold Blocks accented by Glowstone corners.
- Trusted / Flag Access: Deep Lapis Lazuli Blocks illuminated by Sea Lanterns.
- Stranger / Traveler: Solid Iron Blocks finished with Shroomlight indicators.
- Companion Mod Auto-Sync: Equipping selection tools instantly signals our networking bridge, updating client-side renderers smoothly before the player even crosses a claim border.
🛑 Hardened Exploit Protections
- Piston Redstone Shielding: When
piston_protectionis enabled, external flying machines, sweeping blocks, or glitch mechanisms trying to move materials inside your perimeter are completely blocked at the border. - Fluid Displacement Containment: Prevents griefers from pouring massive lava towers or water cascades outside your claims to flood your builds.
- Anti-Kick Teleport Exploits: When an administrator or claim owner kicks a trespasser with
/claim kick, the player's last position is securely logged. This prevents them from instantly utilizing command pathways like/backor/dbackto return to their target.

ClaimMod officially supports fabric for Minecraft 26.2, 26.1.2, 26.1.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with ClaimMod – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if ClaimMod consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
