POST DC3

David Mazieres from the Stanford Future of Digital Currency Initiative gave an interesting presentation at the DC3 Conference in January, in which he talked about the minimum functionality requirements for a digital currency API and made the case for Open APIs to provide what I could open, transparent and non-discriminatory access to digital currency. I found his comments about blocks really interesting (the need for transactions within a block to  be commutative) even though I suspect that retail CBDCs will not be implemented using blocks (or chains, for that matter).
