==== How Bitcoin and Digital Money Are Challenging the Global Economic Order ====
==== Michael J. Casey and Paul Vigna . Tigard 332.42 VIG 2015 ====

Skimmed, did not read.  Economics, not technology.

=== The Truth Machine ===
==== The Blockchain and the Future of Everything ====
==== Michael J. Casey and Paul Vigna . Central 332.178 C3385t 2018 ====
