Re: [Din] WSJ article on Identity and Blockchains

very nice article...

so you _are_ your social network...in terms of trustworthy identity...sure...

there's two problems with this though in details...
i.e. how we build on this idea technically in the Din context...

1/ its still dependent on technologies, 
and there's a seperate issue of why we trust them to proxy our social net -
i certainly would it find it hard to trust any social media app, running on a cloud platform,
using a smart mobile device, to vouch for all these friends & colleagues - too many layers, too many
vested interests, too much Cambridge Analytica :)

2/ I though many people in the security community were moving away from
proving identity, towards systems that prove entitlement (i.e. credentials
are on a need-to-know basis, so if you were say 19, you don't need to say yur age or show id, 
but you can't buy a drink in cambridge MA, but you can in cambridge, UK :)

bootstrapping something from a BC to provide the credentials is also problematic, in that
BC needs a PKI to know whether nodes are not sybils, spoofs, etc, so we have a circular dependance, no?

maybe i missed an important step, if so, sorry!
