Technical Notes

NBT (Named Binary Tag)

It is the file format used by Minecraft to store structured game data in a compact, efficient, and hierarchical manner. NBT is designed to handle the vast amounts of data Minecraft needs to track, such as player stats, world metadata, entity data, and block states.
