Kind of like we have to give the prize to the 2nd or 3rd place runner, cause the 1st one was too fast.
It would affect staking for a lot of users, but would be worth it, if it could remove the 51% vulnerability for all POS coins.
but you didn't solve anything... how do you know the 2nd or 3rd place runners are not the attacker? maybe he placed the first one to trick you into selecting the second one which is also his...
The chance of forging a block does not depend on how long it is since the previous block you forged. It depends on what fraction of the forging coins you have.
It depends on both. Your "hit" is calculated by multiplying your stake by the seconds since the last block.
What is your criteria for a successful attack?
this one is easy: either successful double spend or proving you have 10 (or whatever is required for confirmation) blocks in a row.
I did both for Apex.
