Georgia Gov. Brian Kemp's decision to name Kelly Loeffler as interim U.S. senator has generated lots of political buzz, due to some Trump loyalists claiming betrayal.

Why it matters: The intra-GOP skirmish has obscured the big business story, in that Loeffler will become one of precious few senators with a working knowledge of technology and, in particular, blockchain technology.
