To start I love the Decred project and think it has a great future, but something i was thinking was that technically lets say the price went up a bunch, with the current ticket voting system couldnt some whales come in buy a ton of tickets and vote for things they know are bad for decred? I know that the point of buying the ticket is that your locking in an amount so you havee skin in the game but in the future couldnt say a bank buy a ton of tickets and deciede the fate with negative intentions? And couldnt it become so much for tickets that normal people couldnt afford it
The short answer: no, such an attack is not really feasible. There's been a number of discussions/thought exercises on that topic, and basically it comes down to "no". The protocol is designed to defend against such things. You have to consider the number of tickets that can be bought in a block, the amount of DCR such an attack would cost, the amount of DCR in circulation, and of course, the difficulty adjustment algo of PoS in and of itself.
Not to mention the very unique manner in which PoW miners and PoS voters create and validate blocks.
