SWIFT (https://www.swift.com/) is an international arrangement to transfer money. It deals in all-electronic cash, just like Bitcoin. It keeps records of all transfers, just like Bitcoin. It handles a trillion (U.S.) dollars a day.

Unlike Bitcoin it is used by all countries. I'm not sure that all of the distributed Bitcoin journals can handle the volume. Imagine your Bitcoin journal trying to clear a (U.S.) billion transactions a day.
