About this Mod

Block4Block logo, a lectern with a book on top, the lectern is also a house with a red mat, steps and a green door.

Block4Block introduces a unique mechanic where you need a block to break a block, changing how you gather resources and survive.

Here's what sets it apart:

  • Unique Resource Gathering: Breaking blocks now costs a block.
  • Land Claims: Players use lecterns and books to establish land claims.
  • Claims can trade hands. Protect them.
  • Vanilla Integration: It aims to improve the vanilla Minecraft experience subtly, with in-universe implementations rather than relying on commands or menus.
  • Technical Farms & Inventions: It enables new and interesting farm designs and inventions.

Note: It requires both a plugin and a datapack to function correctly.

Open Source and made to be customizable for hosts to create the experience they want.
