Actually, this might not be the case as I've learned just recently. I've made a thread about a Microsoft patent for crypto mining using human body activity data (you can read about this thing here as a part of debunking a myth). I know it's just a patent, but still.

I don't quite understand why they're even mentioning Bitcoin if what they use is, if I understood correctly, just Blockchain but not for currency purposes. There've been minor projects offering something like this, and now one of them is becoming big because of collaboration with Microsoft. I must say I feel concerned about this idea of strong digital identity because it can be exploited by companies exactly like Microsoft to push adds and more.
