In my line of work, I get a lot of e-mail, actually make that a LOT of e-mail. The topics range across all modes of freight transportation, to be sure, as well as policy and technology. One common theme in more than a few e-mails that has come in over the last several months, and even longer, centers around blockchain technology and its impact, or rather potential impact, on myriad aspects of freight transportation, supply chain, and logistics operations.
