Ah, didn't know that, and didn't think to check that because POS wasn't supposed to start until block 2000. Can't find any now, but I'm pretty sure I saw some blocks that said "mint 23" after clicking on the "i" similarly to how block 1 minted 10,900,000 coins. The latest 23 coin transactions appear to be POS rewards (even though we aren't at block 2000) and don't have the word "mint" after you click on the "i."
What the hell is going on?
My guess would be that it's currently in hybrid POW/POS mode and will go POS-only at block 2000. I think that's how Blackcoin did it (different block number of course). I doubt ION devs would have invented something new here.
