Like the sibling says, Nano doesn't even require proof of stake. It's an impressive design, much more innovative than the average "let's fork Bitcoin" project, but it hasn't been very popular for some reason. Sending money is instant (as in, sub-second), doesn't require confirmations or mining. It seems too good to be true, but I've read the white paper and can't find a flaw (doesn't mean there aren't any, of course). My only criticism is that running a validator node isn't incentivized, which might be an issue, but due to the design of the coin you only need people to choose enough different validator that one doesn't have a significant percentage of people on it.
