StoneBlock 4 Server (SB4): Public StoneBlock Multiplayer
SiriusMC runs a public StoneBlock 4 (SB4) server: no whitelist, 24/7 uptime, free to join. StoneBlock 4 is the latest in the StoneBlock series where you start trapped in solid stone and mine, automate and quest your way out. Our server is tuned for long-running multiplayer play with land claims and an economy.
About
StoneBlock 4 takes the classic StoneBlock loop, where you spawn inside an infinite stone world and progress through tech, magic and resource automation to break out, and layers modern mods on top for Minecraft 1.21. It is the perfect middle ground between a full kitchen-sink modpack like ATM10 and a pure skyblock.
Playing StoneBlock on multiplayer means you share quest progression with friends, can divide up automation responsibilities and keep the world alive 24/7 so your machines keep running while you are offline. Our SB4 server has land claims, chest protection and a server-side economy so trading between players is safe.
