This article is about the block. For the Minecraft edition, see Bedrock Edition.

	“	Bedrock lives at the bottom of the overworld and the top and bottom of the Nether. It was added on the tenth day of Minecraft's development - 20 May 2009 - only three days after the game was released to the public for the first time. It's older than water, lava, ores and logs. But dirt, grass and stone are older still.	„

Bedrock is a block, indestructible by survival means.

Obtaining

Bedrock cannot be broken using any tools. It also cannot be moved by pistons or destroyed by explosions that are present in survival gameplay. Bedrock can only be obtained by the creative inventory and commands. Even if theoretically broken, bedrock would not drop as an item.

Natural generation

Bedrock comprises the bottom-most 5 layers of the Overworld in a rough pattern, although to the 4th layer is predominantly flat bedrock with only rare gaps, rendering the very bottom 5th layer mostly inaccessible. In the Nether, bedrock comprises both the top and bottom 4 layers in a rough pattern. At the top of the Nether, bedrock prevents the player from going past layer 127. It can also be found at the sides of the Nether ^{[Legacy Console Edition only]}.

In the End, individual bedrock blocks make up the natural end crystal structure, and the bedrock remains after the destruction of the crystal. Bedrock additionally forms as part of end gateway portals, created when the dragon is killed, and as part of the bedrock exit portal which is generated at the center of the central End island.

Usage

Bedrock's primary usage is as a solid unbreakable block. It also prevents mob spawns and is the only solid block that beacon beams can shine through. When placed above a beacon on the Console Edition, it will turn the beam black.

Additionally, when in the End and set on fire, the fire on bedrock will never go out naturally, similarly to netherrack.

History

Classic
0.0.12a					Added bedrock.
					The walls of the map are lined with a bedrock textured barrier. It is completely unbreakable.
0.0.20a					Bedrock now cannot be placed or destroyed, except by players on servers with operator permissions. Ops can destroy bedrock like any other block.
					Ops can use /solid, which will toggle stone placing itself or turning into bedrock shortly.
					If any player attempts to place bedrock using an item hacked into their inventory, the server will kick them, even if they are an operator.
Indev
?					Unbreakable, but bedrock on the bottom of the map will turn to lava after a while if it is exposed to sunlight. Bedrock during this development stage was smooth.
Infdev
?					Bedrock was unbreakable with no exceptions.
Alpha
1.2.0					The Nether was added, with bedrock at the top and bottom.
Beta
1.3					Bedrock could no longer be destroyed by planting a seed below it on tilled dirt.
1.6					A bug was fixed in which you could fall into the void. Destroying a boat or rails with a minecart on the lowest bedrock block caused this to happen.
1.8					Creative mode is added, in which bedrock can be placed and destroyed instantly, as can any other block.
					Notch tweeted he had accidentally done something to the bedrock layer, but didn't specify what.
Official release
1.0.0			Beta 1.9-pre6		The particle effect can now be turned off or lowered.
					When the Ender Dragon dies, it leaves behind a fountain-like bedrock structure with the dragon egg sitting on top. It has another end portal to return to the player's spawn point.
					End crystal added, an entity that sits atop of a block of flaming bedrock.
1.2.1			12w07a		As the max world height of the Nether was increased to 256, but Nether world generation is unchanged, mobs and mushrooms were spawning on top of the bedrock ceiling.
			12w07b		Mobs cannot spawn on bedrock.
			?		With the addition of lakes (of lava and water) at any height, it was possible for a lake to cause an unusually large gap in the bedrock. This was fixed in release 1.2.
1.2.5					Bedrock in the End will burn forever if set on fire, similar to netherrack. It can still be put out by the same methods, as well.
1.8			14w27b		Bedrock's texture now rotates randomly, giving a more natural look to the bedrock layer.
			14w34c		Removed bedrock "depthsuspend" particle.
1.8.2			pre5		Bedrock no longer obstructs beacon activation or beams.
1.9			15w31a		The Ender Dragon no longer creates the exit portal upon death, with it instead generating with the world.
					Bedrock forms part of the end gateway portal.
			16w02a		Bedrock can no longer drop itself as an item.
Pocket Edition Alpha
0.1.0					Added bedrock.
					Bedrock appears at the bottom of the world, but is unobtainable even in Creative mode.
0.8.0			build 3		Added bedrock to Creative mode.
0.9.0			build 1		Added bedrock fog.
0.12.1			build 1		Bedrock now generates in the Nether.
Pocket Edition
1.0			build 1		Bedrock now generates in the End.
Legacy Console Edition
TU1	CU1	1.0	Patch 1		Added bedrock.
TU14		1.04			The bedrock on layer 0 can now be broken in a world. However, the player still cannot fall out of the world.
