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 nothing when broken, and breaks instantly with any tool.

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. It is 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.

Examples of the unknown block naturally generating include placing an add-on and then removing the add-on from the world, or placing an Minecraft Education-exclusive block and loading the world on a vanilla version.

Behavior

The unknown block breaks instantly, and is able to be placed if it has been converted to the unknown identifier. If it still retains the invalid identifier, such as when obtained via pick block, it cannot be placed, though it flashes briefly on the client. Like ice, it has low friction, but only for the player. When the player moves on it, the movement stutters, teleporting the player slightly forward or backward. When attempting to drop the item from the hotbar, it plays the sound but remains in the inventory triggering the pick up item animation. The item can be disposed by dropping it from the inventory or destroying it in the Creative inventory.
