Help On place of block

[Godtitan]

How can I make it so if a player places a block, players can break those blocks placed by a player

This is what i have for temporary blocks but i want players to be able to break these temporary blocks

on place:
if player's world is "FFA":
wait 10 seconds
set event-block to air

I would also use world guard to prevent them from breaking the build, but they can break the blocks placed by players.

So you want to that the player who place the block will be only player who can break until it will be gone?

So what do you really need help with? The block to dissapear after 10 seconds or what?
