 Well, as part of the detailed currency global initiative, the objectives of this particular group is to come up with the first areas that could be subject to standardization. It's not an standardization effort per se, but the idea here is to at least identify first which areas would be interesting for them doing further work towards standardization. What we're talking about detailed currencies is a relatively new subject. And we are studying different types of detailed currencies, starting with wholesale CBDCs, retail CBDCs, then electronic money, bank coins, that sort of thing. Also, cryptocurrencies, also stable coins, these different things. They're different in nature. Some are more regulated, some are not regulated at all. But we believe or we hope that there will be, for example, common architectural patterns that could be areas in which actually we could use some standardization as to how to use them, how to manage them, how to visualize them. So that's the objective of the group, is to understand the different patterns and try to come up with some common patterns that could constitute areas for standardization for their work at ITU. So in the working group, we have a split by the broad types of detailed currencies. So we are studying differently, let's say, the different types of detailed currencies, including retail CBDCs, wholesale CBDCs, stable coins, and also cryptocurrencies and electronic money. The way in which we work is, first of all, we wanted to do an exhaustive work in terms of identifying the leading use cases, I mean, the leading cases studies. So what are the major initiatives out there in the industry in each of these categories? Many are experimental, right? Many are still things that are under research and formation. Some others are a lot more advanced. Some of them are actually even going to go in production in the next months. So the first idea was to, first of all, come up with a, well, as comprehensive as possible, set of reference cases studies, right? And study them from an architectural point of view, how they work, how they are built. And so we have at least the basic information to then do recognition of the patterns that could be common to all of those, right? The next focus is going to be once we've done a first recopulation of all these cases studies, then the next step is going to be to do some more analysis and then trying to come up with the common architectural patterns to identify then the potential areas for instantarization. So that's what the working group is all about. We are, I think, a year and a half already into this. And hopefully during 2022, we'll start coming with some conclusions.
