Canonizer.com makes decisions like this by meritocracy consensus delegated from the masses. Let's say everyone holding the currency gets a vote for each coin they own. Let's say lots of my friends and family aren't much interested in what makes a good collateral rate, and they know I'm a much better, interested expert than they. So they delegate all their coin votes to me. I, in turn, may delegate my entire tree of delegated coin votes to someone I think is far more intelligent than I, like Dan.
So Dan could have a large enough delegated authority to control significant changes in the entire network. And you could trust that everyone that mattered would be instantly fully on board with any decision he made, the instant he made it.
The instant he jumped to a camp requiring twice the equity, taking all his delegated coin votes with him, that could become the new consensus camp the entire network could then trust to use. If Dan ever screwed up, everyone would quickly delegate their authority to someone they trust better. This would give the system the power and agility of a hierarchy, with all authority being derived from the bottom up. Essentially a hyper delegate decision making meritocracy authority that in real time knows what everyone that matters is and isn't on board with, why, and what would be required to get them on board, and so on. This is part of what it means to amplify, educate and rigorously measure, concisely and quantitatively, the wisdom of the crowd.
