I want to create a Minecraft plugin for 1.21.11 Paper. It is fairly simple. Players can claim chunks using /claim. In a claimed chunk, other players are not allowed to build, break blocks, or engage in PvP. The player who claimed the chunk can add other players using /claim trust (player). Trusted players are then allowed to build and break blocks, but not PvP. When you enter your own or someone else's claimed chunk, you receive a message in chat or on screen. For example: "Chunk claimed by: (player)" Additionally, players should be able to unclaim land using /unclaim. Claimed chunks must be stored per player in a database, and all messages should be customizable.
