Did they end up solving the "nothing at stake" problem?

Yes. With Ethereum’s PoS system, you get penalized for voting in multiple forks.

See https://eth.wiki/en/concepts/proof-of-stake-faqs (I can’t link to the paragraph).

The "What is the “nothing at stake” problem and how can it be fixed?" proposes 2 solutions. Which one does ethereum use? The page itself is pretty long, and I can't find an answer with a quick skim.
