Bedrock
Bedrock is an unobtainable block that cannot be broken or obtained in survival.
Due to the addition of AnarchyExploitFixes and Toms3Core, nobody can hold or have bedrock in their inventory, as it's removed the moment it's interacted (As of July this is not a thing anymore, as illegals got "unpatched").
This can be bypassed, as doodooboy123 and messytailz have been seen carrying it.
Location
I found only 2 near spawn.
First: X: 253, Y: 266 Z: -70
Second: X: 251, Y: 266, Z: -71
How was it obtained?
JakePlaque obtained it by begging K7rau (as jake said, kurau was high on weed, lmfao) and placed it here.
Extra info
Theres end portal frames nearby too.
K7rau placed them with /setblock. He used that same method to place end portal frames, end portal, end gateways, nether portals, and more.
