What is the actual rarest block in Scratch? I can't seem to find the answer. Is there even a rarest block?

There is no rarest block, because all blocks can be created and backpacked an infinite number of times. But, the technical answer is blocks for changing specific variables, because there are quadrillions (probably way way more) possible variable names, having any random keyboard-smash variable name is technical the rarest block.

Alright thanks!

Do you mean the least used block?
Also, there are a few removed ones that are still here, but yeah.

Also, json hacking.

Excluding custom blocks, variables, extensions, and JSON editing, it would probably be the “forever if” C block

(This was removed in Scratch 2.0 because it was unnecessary)

Does that count though because it doesn’t even exist anymore and converts to an if statement in a forever loop when loaded in 2.0 or later?

Well if it doesn't exist anymore then I don't think that should be counted

THERE MOST RARE BLOCK IS RED HACKED BLOCK AND UNDEFINED BLOCK

If you're talking about the Undefined Hat Block, then it's easy to obtain, but if you're talking about this one:

undefined ::undefined

Then that block disappears when loaded into 3.0, so I don't think it counts.
Also, would this count hacked or undefined blocks, or what?

No, it would be this (you never said lists):

(hrejwkmrfngthre43jwkasjehgrbvdwnqmjk2w3ie4uryfgbmediansfyrueidfjhyreuikj :: list)

They probably mean everything in the Data category. And even if they didn't list it, I don't think that would count because it's still the list reporter block, even if you put a different name.

I don’t know if anybody really keeps track

If we're counting extensions here, probably the micro:bit blocks or the Force and Acceleration blocks

Force and acceleration?
Also, maybe one of the Lego ones?

And then Makey Makey

well i dont know what forcing acceleration is in stretch so LOL
Anyway, I think the only reason Makey Makey is used at this point is because of the reporter dropdown thing LOL

rarest block is

([ v] of [Sprite1 v])

beacouse it isn't in editor

have you seen the amount of really complex things that use that block
