I've seen lots of "DAC" ideas around here that seem to totally miss the point. The purpose of a DAC is to cause the emergent behavior of a large network of people to behave in a way that a centralized entity could not, while adding value for all participants. Most of what I've seen is just "let's take this business model and put it on a blockchain" - almost always it seems *worse* than a centralized solution.
So here's the litmus test: Which
social dillemma is your DAC addressing, and which
payoff matrix is flipped as a result of adding the blockchain?
For BTS DNS: Each individual benefits from having squatted a successful domain, while the collective as a whole suffers from the lack of available domains. By the auction/dividend model, it is now *more profitable not to squat than to squat*.
For BTS X: It is *more profitable* to participate in the market peg than to fight it.
For Bitcoin: It is *more profitable* to be an honest miner than a dishonest miner.
