A friend of mine sat in on this session. He summarized ...
'Totally fascinating. A group of decentralists listening to a centralist and thinking he was a decentralist!'
The concept is that each individual signs up to a platform that then can do commerce with any other platform. A bit like joining a co-operative and being able to shop in all of the stores that the co-op has done a deal with. Or, a standard 3-party transaction.
And, as we know, the challenge with 3-party transactions is identity!
But, the good thing is they will need identity unless they limit themselves to online or build a tunneling solution!
More to come with time. Just dropping this in here for now.
