How to earn more PPC using PoS blocks
PPC besides the "normal" Proof of Work (PoW) blocks has also the capability to generate you new coins using Proof of Stake (PoS). Many miners don't know what this is and how it works, so I'll try to explain in simple terms.
Proof of stake is a method of securing the network. And it's a system that rewards the miners for helping securing the network. They do this by minting PoS blocks. PoS blocks are similar to PoW blocks. Except no power hungry mining is required to earn them. They secure the network in the same way as PoW blocks and make 51% attacks very difficult. You would need to have a sufficient amount of the currency up to 51% as well as 51% of the hashpower to invalidate both the PoS and PoW blocks making a 51% attack very costly.
Now, how do I get more coins? Easy! All users with a wallet running with coins older that 30 days are able to generate new blocks. The network will generate a new block using some coins of your wallet (locking them during the normal 520 confirmations used on PPC). At the end of the 520 confirmations, you get your coins back plus a reward for having your coins locked to generate a new block!
See, that's easy!
