Note that we aren't implementing any sub-block-transfer thingies at this point.
(I expect that the currently implemented full-block-transfers will work fine for
the forseeable future.)
I suspect that Tschechow specified blocklets in order to get cryptographic
authentication on each transferred unit.
Another solution for cryptographic authentication of sub-block units would be a
hash tree. e.g. THEX:
