@hvdsomp @cogdog It's the chain of trust created by the "vouches" idea I think. So, you start with someone that you actually know and trust and work from there, in a series of "hops".

I'm not convinced that this is viable to be honest - as you say, it seems like it would nonetheless be open to bing corrupted.

But I am interested to see such attempts emerging - and it's easy to experiment with. Also - it's a statement - even if others make the same claim insincerely.
