Solved On break block genered naturally or placed players

[VOIDDER]

Help, I ran out of ideas on how to implement this...
How to check if the block that the player broke was placed by the player or appeared naturally?

on break:
if event-block is coal ore:
(and how to check, I don't know, help me plz)

This is the only solution I can come up with

on place:
   add location of event-block to {playerblocks::*}

on break:
    if {playerblocks::*} contains location of event-block:
        send "block placed by player"
    else:
        send "block not placed by player"
    remove location of event-block from {playerblocks::*}

command /removeplayerblocks [<text>]:
    trigger:
        loop {playerblocks::*}:
            set block at loop-value to air
        send "All blocks placed by players got removed"

Not tested, not sure if it works

Is there a possibility without recording? In the minecraft itself, is there no information whether this block was put or was generated. core protect takes data from somewhere...

Unfortunately this is the only solution I came up with. I'm not sure how core protect works, never used it.
