I am trying to understand the feaures of Decred.
Am I right on this: For the voting process you have to buy tickets (like a lottery). With these tickets you can vote for changes (e.g. Block size) or to rate the last mined block as valid etc. The more tickets you have the higher impact for the voting process is.

Am I right on this? This seems to be special for Decred (beside Hybrid PoW/PoS).
