Thanks all for your input, opinions and ideas. I'm swept up in some real world business that will keep me afk for the next 2 or 3 weeks, but I'll reply properly when I can. A vague plan is slowly hatching.
As an aside, I've noticed recently several communities concerned that their project of choice might be running out of funds. I want to assure all of you that there's no danger of that here... we don't have a dime and we never did!

We should change that though. More to follow. Stay safe!
Hey KingCaper, I had this idea for a blockchain project, I think it's inline with MOIN's values as a privacy project. It's a method of creating a two-factor / multi-factor authentication system leveraging a blockchain network. I have created a bit of an overview in the image below. It would be great to get feedback from the wider MOIN community on the concept too.
