+let me give you a quick demo of this protocol. I'm gonna start up an indie agent, and that agent is going to be listening on email, and I'm going to talk to it by email, and I'm gonna use the trust ping protocol to to interact with it.

-you have their D ID for them that's

-the protocol is not modified but by

-adding a little bit of blockchain pixie
+I want basically a virtual megaphone, but here's a "why do I need blockchain?" there's a really good answer to this, I can't build this right now, because if everybody had a real megaphone in real life you'd have problems with people using it irresponsibly, wouldn't you? 
-dust I'll call it I can increase the
+
-trust behind this protocol and and
+So there's a trust problem, I can use blockchain to require people to put stake, or put their identity in escrow against their responsible behavior. So that a person can say, when it's a life-or-death situation, "I need an EpiPen right now!"
-that's the kind of thing that I'm seeing
+
-over and over again as I get my head
+I'm willing to you know have a hundred dollars on the line or I'm willing to have my identity disclosed if I am shown to use that irresponsibly and that protocol can hook back to the blockchain as a basis for that trust but most of everything that's happening is all out on the edge.

-but some entity on the edge yeah and I'm
-really using the term edge of course is
-really vague but what I mean by it
-mostly is it's not the thing in the
-center of the architecture diagram okay
-and then the second question the concept
-of the micro ledger is there any concept
-of persisting the final values of the
-micro ledger onto a blockchain yeah so
-this is if I go back to let's see the
-notion of anchoring something on a
-blockchain a number of people in
-industry are exploring different ways to
-do that and one of the things you could
-anchor on a blockchain is a micro ledger
-so if you needed to prove for example to
-a third party let's say Alice and Bob
-are interacting and it's it's a private
-personal relationship but let's say Bob
-doesn't fully trust Alice and maybe he's
-afraid that alice is gonna steal all of
-his cool music for his next album even
-because he's been sharing it with her so
 he goes and he anchors some things on
 the blockchain to provide evidence so
 that if anybody ever you know if there's
