What do you envision is in the "identity and associated data" ?

What is a personal blockchain?  I am guessing that it is where each 
person constructs a blockchain-like distributed store with all of her 
trusted partners?

Does this mean the trusted partners can recover Alice's "identity" 
without her permission?  If so, how is that mitigated?

In general the system bears close alignment to my design/theory. However 
where it differs is (assuming I am correct in understanding) that you 
postulate each person being the center of their network, and branching 
out to trusted others.  Whereas my work starts from assuming a trusted 
group to which a person joins.  Have you considered groups?

What is the business model by which you intend for this to promulgate?
