mining/minting there are still hashes to be made, arent they?
just that the difficulty is far far lower, because the deterministic factor is not hashpower, but the stake in the coin?
anways, i definitely have to read up in detail on this

I guess you are right. Hashes are being created, but the diff is so low that they are just done almost instantly. Regardless, with a pure POS coin, the POS aspect handles all the transactions and I don't think we need pools for this type of coin.
Can someone with more knowledge on POS confirm this?
