I applaud the cryptography work here, it seems like a damn cool application of ZKPs, but I think their missing what made Bitcoin work. The tech people took to BTC because it was something that they could verify worked correctly, and had no centralized party who could change it on a whim. Once it had the backing of those tech people, <i>then</i> it spread to everyone else. These guys might be able to get a small portion of customers who don&#x27;t care about a centralized party, but that just isn&#x27;t going to be enough, those aren&#x27;t the people who are going to evangelize it.
