This is a question about Blockchain in general, not about Bitcoin as a currency on top of Blockchain technology.
Let's say I want to issue a vote on top of, lets say, multichain. I would issue an asset called "voting_right". Let's say I have 1000 participants, so I create 1000 voting rights and send each participant address one voting right. Everyone can either transfer their vote to somebody else or directly to a vote option.
I don't have given anyone mining permissions, because I don't want anyone to "illegally" earn voting rights. On the other side, I require miners to collect the votes into blocks and prevent double-voting.
- Can there be a Blockchain without miners?
- If no, what I am assuming, is there any danger if I, let's say create two mining-enabled multichain nodes (with 0 reward), 100% controlled by me? How can others trust me?
