Values, axial currencies, and computational axiology: digital currencies can do more than buy stuff

Eleven to twelve thousand years ago, early humans lived in small communities with no discernible hierarchy. The "agrarian revolution" resulted in communities growing on such a scale that mechanisms of self-organization - e.g., for monitoring, keeping order, and ensuring a "satisfactory" allocation of resources - were no longer efficient or effective. However, the concurrent "cognitive" revolution resulted in the faculty of imagination, in particular, the imagination of rules, to solve such problems.
