Would something single sign on (SSO) even be possible? I think the convenience of having a single account for the family of federated platforms would be wildly convenient.
Of course folks could continue to have individual accounts on each platform if they wanted.
I also understand that it would create a very tempting target for hackers and it would need to use MFA (multi factor authentication).
Just a thought and I would like to see you all have to say.
Asking after having this discussion.
I had a drunk conversation about this very thing last weekend with my brother. We thought about doing it as a crypto coin or NFT or some block chain thing. We got about as far as you expect 2 drunk people talking about something that they have a passing familiarity with but little actual technical knowledge of.
Someone much smarter than me might figure it out one day.
