Description

A

A

A

All right here we go.

A

We got tommy online here. He is check the thread.

B

A

All right here we go.

A

Okay, so where were we um oh, I set up down here.

A

And we're going on the chain, so I figured got to put the server on the chain.

A

Wait so yeah, okay, so yeah servers on the chain and I found my ubuntu trusty ubuntu 12.04 usb stick. It was plugged into the server all right. So, um let's see we don't need these. We decided that we, basically we we trust these. uh We trust these verifiable credentials. Folks and- and then I just saw daniel tweeting about it too so must be- must be trustworthy.

A

um Okay, so we are going to and let me maybe or can I let's see noah could comment. Let me drop a link to the discord in the chat. If anybody wants to chat.

A

Where did the discord go.

B

A

B

Expire after never.

B

A

Okay, but we don't have like roles on the server. I don't think.

B

B

A

Do I have my sound on?

A

I do not okay now if anybody joins, oh, I will know.

A

Okay, so where were we, this took me a long time to set this whole cell set about down here. um I hadn't set up down here yet okay, so we decided that we were going to, uh or that was there was the potential to encode our um system context or our manifest or our data flow within the claims of the verifiable kind of credential.

A

um We then uh decided that we really ought to get something working here before we went on um and and tried to actually do that in coding, um so uh we're gonna go, find, uh let's see the last the did. What was oh yeah? No. This is the one that we already found we found um so we found we found this. Let's see, can we make this full screen? Should we have to reload this okay? It just looks like that.

A

Okay, fine, um so we found this uh this thing that basically lists you know a bunch of things that that implement the verifiable uh credential um spec and and which parts that they implement, um and this you know allows the communities to test interoperabilities between specs, um so um credential status. So we we checked out two of these. We looked at open attestation, which we thought could be used for this review system type thing. Then we also looked at this vc.js.

A

And I can't remember what we decided there.

A

I think we decided we liked it.

A

Yeah, this was great yeah. This was great.

A

I did we didn't I. I didn't quite understand it at the time, though okay, so um this library is javascript browser and visitor infliction. Let's reform signing issuing creating a verifiable presentation, verifying it was verifying a stand alone.

A

Okay, so we don't care so much about verifying things at this point just so much as getting it in and out of the data format, um but that's great if it does that, um let's see it allows you, but but the thing is we're writing in python right now and well to do the language compatibility stuff is on the roadmap.

A

I'd like to do this first, do they have any other? So, let's this looks like a really good option, um but we haven't looked at the rest of these to see. If any of these are like, you know, we could also just just google our duckduck. Oh, this should be duckduckgo, so we can google.

A

I like to put sitegithub.com on there, because it just gives you better results than actual github. Oh, and we want um python.

A

This is not ideal.

B

There we go oh azure, look at that.

B

A

Yeah that daniel who works in microsoft, uh this case demos or aries hyperledger, aries cloud agent.

B

A

Okay, so what kind of library does azure use so do they implement it themselves or do they look too.

B

A

Each in this sample will teach you the issue for sure use this card to prove to verify that you are a verified, credential expert mastered in the art of digital credentialing. The sample uses a preview rest api rest api we can use, which supports id token hints to pass payload there's. No, that's it's the same amount of work. um Okay. This is not. Let's see where is yeah?

A

Okay, let's just look for some code, all right. So here we see our well known all right- and this is I'm sure, nobody's gonna- be able to read this in its current state, so uh confidential client application. Okay! So look at this! This looks like already. This looks like this might be where we want to go. So what is this thing import mod this? This look, microsoft, authentication, library, authority, concrete, okay, so yeah?

A

We want this, um see right away, you you find the most most popular uh implementation of like an interactive client, and then you grab the libraries that they're using so.

A

Client credentials and what was it so, how did they use it? Confidential, client, application, okay. So, but what is this.

A

Client credential yeah, okay, good enough. This looks.

B

All right, okay,.

A

Okay, all right, oh man, I really don't okay, so.

A

Run this thing echo.

A

And what does it do.

B

Check if it isn't.

A

Okay, so this is this the thing we're spinning up on: oh, oh, are they using this within azure.

A

B

A

Snazzy all right who wrote this.

A

Oh okay, you seem to know what you're doing um yeah. Okay, what else are you doing this guy's? Probably doing good stuff? So then this yeah, here's another thing. Here's another strategy, this guy. He obviously knows what he's doing. What else is he doing? Maybe he has some kind of you know even more up-to-date thing, that's even more helpful.

A

It's all about we're just doing like you know, gra, it's just like these. These graph search um try to find the most up-to-date train of thought, that's more of the stuff in the discussions thread, and so we're sending out all these, like parallel trains of thought right. So we do have to do this in in in a sequential matter, because we're humans right- and we can only do one thing at a time, but uh with the way that we can build.

A

The the I think, it's really.

A

I'm not even sure I think it's the architecture. I think it's the architecture because there's the architecture and then there's the protocol and yeah. I think it's it's it's. It's almost like the the general algorithm as well, um which.

A

For the general parallel problem solving um so great, so they must be issuing. Let's go read the documentation now that we know what's going on um so welcome to issue issue. Your first credential and you'll use this card to prove to a verifier that you are a verified, credential expert mastered in the art of digital clinician. This sample uses a preview rest api, which supports token api hints to pass payload to the verified full credential.

A

Okay, let's jump through so we read the code, it's kind of like. I guess I approach this kind of like you know, you're going to a class right in college and you're like you read the textbook, and then you read the docs, and then you read the textbook again right and the docs is the lecture. Because that's you know if you get it, if you get docs, then you're lucky so um all right so about the sample. Welcome to there. This sample will teach you to issue. Your first account uh important.

A

uh Currently, public preview preview version uh blah blah contents. Content is divided into two parts, one for issuance and one for verifying a verifiable credential. Depending on the scenario you need, you can remove part one part to verify: your environment is completely working. You can use both parts to issue a verified, credential expert, vc and verify that as well to verify. If your environment is completely working, you can use both parts to issue okay, so basically, okay, I see interesting okay, so um I'm curious to see how that works.

A

That sounds like some sort of self sign setup, all right, so the basic webpage all right. So let's go ahead and run this thing. Is it what flask? It's always fast? um Okay, and look at this we're on windows wow for once, for once, that's a good thing! um Wow shocking things are really all over the place. Lately, all right.

A

We need to clone this thing.

A

So where are we at wsl.

A

Okay, I'm gonna make the font bigger because we're not into anything deep right now- and this is just you know, good stuff- to have on the recording.

A

Oh, that's pretty all right! That's too big.

A

It's still too big, I think 16.

A

All right sure, all right so where, where are we? What are we doing so we're going documents? uh What is this python? I'm gonna get clone all right. So let's go grab this thing.

A

Okay, all right, what do we got read me the same thing we're looking at here: okay, so we'll give it a little trees.

A

This thing's, probably out of date,.
