Unknown is a placeholder block exclusive to Bedrock Edition that generates in place where blocks have an invalid ID or invalid components in their behavior files. If the block has a unique model, it takes the shape of that model.

Obtaining

Breaking

The unknown block drops itself when broken, and breaks instantly with any tool.

Block	Unknown
Hardness	0
Breaking time (secs)

Legend

• correct tool, drops nothing or something other than the block itself
• correct tool, drops the block itself
• italicized can be instant mined

Natural generation

Loading a block with an incorrect ID in any world results in it being replaced by an unknown block, although it retains its ID. The ID is not retained upon being broken. Often caused by corruption or force opening a world of a higher version than the client, as the game does not recognize the id of newer blocks. An example of Unknown naturally generating is when you place a block that was added from an Add-on then said Add-on is removed.

Behavior

The unknown block breaks instantly, and is able to be placed. Like ice, it has low friction.
