The Morning After: Cryptocurrency may be more centralized than you thought

One of the boons of cryptocurrency is meant to be that no particular company, central bank or government has control. That might not be true. Researchers for a report commissioned by the Defense Advanced Research Projects Agency (DARPA) found there can be "unintended centralities" in these supposed decentralized systems. Cryptocurrency power is concentrated among people or organizations with a large chunk of the pie. "Unintended centralities" was the term used, defined as circumstances where an entity has sway over a so-called decentralized system.
