Bedrock

Natural generation

Bedrock comprises the 5 bottom most layers of the Overworld in a rough pattern, although the first to fourth layers are predominantly flat bedrock with only rare gaps, rendering the very bottom, completely flat fifth layer (at y=0) mostly inaccessible. In the Nether, bedrock comprises both the top and bottom four layers in a rough pattern. At the top of the Nether, bedrock prevents the player from going past y=127.

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 the exit portal that generates at the center of the central End island. In Bedrock Edition, if one manages to break the bedrock in the exit portal, the bedrock reappears when the portal regenerates.

End gateway portals are also generated upon killing the ender dragon. However, only 20 of these portals generate, in set positions, with one appearing per dragon kill. Additional end gateways are also generated in the outer End regions after activating end gateways at the main island.

Info

Bedrock's primary usage is as a solid unbreakable block. It cannot be moved by pistons.

.

Additionally, when set on fire in the End, the fire on bedrock never extinguishes naturally, similarly to the fire on netherrack.

Notes (do not assume everything is sure and verified)|

It is the only block that is unbreakable. (except in creative)

It too is the only block found at the bottom of your realm/world.

It is flammable and never extinguishes (as long a your in the end)

Its hardness is over 18,000,000

Trivia

Many YouTubers tried to break it and they spend weeks breaking it

It is 100x Harder than Obsidian

Usage

It is used in PVP Creative, It is used due to the fact it can't blow up

If you use it in PVP Creative. Make a SkyBase that way the rival/enemy won't destroy your base.

though you have to find your way out, you can be stuck for ages.

It is highly recommended that when making a SkyBase/Basement/House leave your roof open or you won't be able to get out. (you'll need blocks also)
