OneBlock SMP
by Subutai
OneBlock SMP gives each player a private island that starts as a single block over the void, with 11 progression phases that open up as the block is broken.
What it does
The mod is a server-side Fabric mod built around a OneBlock survival loop. Each player starts on a personal island with one block floating over the void. Breaking it leaves a new one in its place, and progression moves through a series of biomes and dimensions that ends in the End. Islands are spaced 1000 blocks apart by default, and a claim radius of 100 blocks around each island protects it from other players.
Players progress independently, and visiting a friend's world only lets them build on their own island. Competitive events include Block Hunt, Mining Challenge and Scavenger Hunt, plus a leaderboard that tracks blocks broken and the furthest phase reached, shown in the scoreboard sidebar and tab list. Players can earn OneCoins from placing events, reaching new phases or playing in the protected hub, then spend them at six villager-run shops.
The phase data, mob spawns, loot, shop inventories and prices are defined in JSON, so server operators can rewrite the economy. Spacing, claim radius and event timing are configurable by the server. Only the server needs the mod's data, and the environment is client and server, so every player needs it too. Installation requires Fabric Loader and Fabric API alongside the mod. Files cover 26.1, 26.1.1 and 26.1.2, with 1.0.10 for 26.1.2 as the latest build, and the mod is released under All rights reserved.

OneBlock SMP drops each player onto a single block floating over the void. Break it, and a new one appears. That's your entire world — build it from nothing. Plains → Forest → Caves → Desert → Swamp → Taiga → Jungle → Underground → Deep Dark → Nether → End
