Proof of Stake...

The problem is that there's nothing preventing hosts from mining on forks
simultaneously. In bitcoin, if you mine on forks simultaneously you'll be
working with different headers and wasting hashes. In POS, you have nothing
to lose from mining forks, and then picking the fork that benefits you the
greatest.

Some bitcoin devs have called it the nothing-at-stake problem.
