I mean, it’s not as if stock exchanges were working that well at the moment even though they’re opaque… A centralized blockchain vs a centralized database like is used at the moment isn’t much different, except that in the first case at least everyone can see what’s going on behind the curtain if they feel like it… Same principle as open source projects, the program runs no matter if the code is made public or not, but if it’s made public the people who are interested in that can at least check how things work.
