Sybil attacks can happen in many different ways.

Like rigging the voting on the monthly budgets. If you have, say 600 Masternodes, which one or more of the DASH shills do, then you can just vote for what you want. Or you can just co-ordinate how you want a vote to go with a core group.

Is DASH Sybil resistant? No.

Game over. Close the thread.
