Hi,
  Additionally refer
https://edition.cnn.com/2022/03/11/tech/us-digital-dollar-cbdc/index.html

  Quote from the above
  " All told, around 100 countries are exploring CBDCs at one level or
another, International Monetary Fund managing director Kristalina
Georgieva said during remarks at the Atlantic Council think tank last
month.  "
  So there is acceptance also.

  Please analyze the SPAM in Complete Cashless Economy and Complete
Multimedia Recording environment. When there is end-to-end
traceability, we can know the source of income of Spammers. Spammers
can not lie about the volume. This co-relation can force the penalties
for spammers and spam call volume will be reduced drastically.
  Apart from SPAM, these fixes other malpractices also.

originated in the FCC robocall strike force a few years ago, with lots
of carrier participation, so you could go back to the various FCC
reports that were produced at the time for the motivation and
background (e.g.,
https://transition.fcc.gov/cgb/Robocall-Strike-Force-Final-Report.pdf
and https://www.fcc.gov/file/12311/download). This I-D and
requirements have been discussed since 2017, so this is hardly a new
idea. The draft itself has been through IESG review - I just never got
around to implement the changes requested.
The basic requirement is that we want the receiving callee to make
automated or semi-automated judgements. Currently, the RCD draft has a
free-form field, but that doesn't really help for anything automated
(or, say, displaying icons or other graphical elements).
Like all spam labeling, this is probabilistic, i.e.,  if you're
waiting for perfection, this isn't for you. Current robocall filtering
services already label numbers with categories (they are in the same
ballpark, but not exactly the same and each seems to differ a bit).
There are at least two possible sources:
* For some labels, the calling party (with signing) will insert the
information, presumably for the more "positive" labels like "health"
or "government" or "personal". If a carrier lies, this becomes either
a reputational issue ("never trust labels from carrier X") or
enforcement matter (e.g., as a potential deficiency in robocall
mitigation). The label may be part of the KYC process when a carrier
signs up a customer - after all, in almost all cases this is pretty
obvious ("your business says Joe's Travel Agency. You are picking the
healthcare designation how?") A terminating carrier may, for example,
decide to only trust known carriers (say, T-Mobile) in deciding
whether to convey this information to the called party.
* An intermediary service used by the terminating carrier labels
(signed) numbers based on honeypots, crowdsourcing or number
databases, probably more focused on negative labels like
"telemarketing" or "fraud". Again, versions of this exist today.

  Hi Henning,  
  Interesting idea, but who could define the categories, and who would
verify the claims?  
  There may be something here, but this is a good example of where we
should agree the use cases and then define requirements before leaping
to solutions.

  In trying to get back to looking at my ancient, dusty draft, a
thought: I think RCD would be significantly more useful if it
contained standardized categories of callers, such as the one included
in callinfo-spam. This allows much better user  interfaces and
automated handling ("send all political calls to voicemail", "play
special ringtone for personal calls").
