Bedrock is both an indestructible and unmineable block. The primary function of bedrock is to create an impassable barrier at the bottom of the Overworld and at the top and bottom of the Nether. It can also be used by server administrators to create an inescapable "Jail", for disruptive or otherwise uncooperative players.
Bedrock spawns in the bottom five layers of the Overworld, in random heights, and the top and bottom four layers of the Nether.
