According to [it's official page](http://www.blackcoin.co/), Blackcoin used scrypt as its Proof-of-Work during the phase of initial coins' creation. But now it's purely Proof-of-Stake, and they claim to have a speed of just 10 seconds for first confirmation (and only needing 10 confirmations to get an almost guaranteed transaction).

* How does their pure PoS model serve to verify transactions, without the risk of double spends?
* How can they create blocks as often as 10 seconds without having massive amounts of orphans?
