> ...what happens when I borrow enough ETH to win blocks, deliberately mis-verify TX... Ethereum already "slashes" the staked ETHs of those who try to game the system (Ethereum already has one chain on PoS): the coins of stakes who try to cheat the system are not even confiscated, they're destroyed (making every other holder a little bit richer). I don't know if this shall work or not, but that's their plan to keep bad actors from trying to attack the system.
