Bedrock

Bedrock is an indestructible block which is found at the very bottom of the Overworld. There are no tools in vanilla Minecraft which can break Bedrock.

It spawns at the very bottom of the Overworld and on top and the bottom of the Nether in Vanilla.

Obtaining
Bedrock cannot be obtained through any normal means in survival mode, although there are a few mods which add the ability to obtain it. It does not drop as an item even if it is broken in survival. The only way to get the object in the Java Edition of Minecraft is to turn on Creative mode and add it into your inventory. However, in Bedrock Edition, there exists a few glitches that allows you to obtain it in Survival.

Usage
Bedrock does not have any known usage in major Minecraft mods. The primary usage is a solid, unbreakable block, which cannot be moved by pistons.

When Bedrock is set on fire in The End, the fire does not extinguish similar to Netherrack.
