# Verifiable Organizations Network: A Production Government Deployment of Hyperledger Indy—Hyperledger Global Forum 2018
|
||||
|
||||
John Jordan, Province of British Columbia & Stephen Curran , CloudCompass Computing, Inc.
|
||||
|
||||
Learn about the Province of British Columbia's experience deploying the first Hyperledger Indy based production ecosystem.
|
||||
|
||||
The Verifiable Organizations Network (VON) enables governments and organizations to exchange data in trustworthy ways based on open standards and technology.
|
||||
|
||||
VON's founding members are governments who are, by law, trusted issuers of data about organizations. The Province of British Columbia, Province of Ontario and the Government of Canada have come together to create the initial services needed to establish VON.
|
||||
|
||||
VON's founders have delivered new Indy-based open source components which form VON's backbone. TheOrgBook is a publicly accessible repository of verifiable claims about organizations. VON-X enables services to verify and issue credentials.
|
||||
|
||||
We present the Why, What and How including our strategy for bootstrapping VON using a two-sided market strategy.

## Transcript
|
||||
|
||||
<code>**Editors Note** I just copy pasted this from youtube's transcript of the video, broke up text so it was easier to read, and added screenshots of different slides for context. It will be nice eventually to clean up the text.
|
||||
|
||||
**Pull Requests Welcome**</code>
|
||||
|
||||
so my name is John Jordan and I come from the province of British Columbia in Canada this is my colleague Steven Curran we work together on this project
|
||||
|
||||
we're gonna talk about today so I guess I'll just get started and we'll have some slides a demo we should have some
|
||||
time for some questions
|
||||
|
||||
so ian is also here are there colleague Ian over here one of our developers as well he's a he's a hyper ledger future developer so what we're gonna talk about today is sort of what we're doing in the government of British Columbia and together with some of our pure provinces in the country about how we're trying to solve some very long-standing difficult
|
||||
problems
|
||||
|
||||
<img src="http://i.imgur.com/bf3lLTq.png"/>
|
||||
|
||||
we're gonna focus on business services today and we're gonna talk about how the government can start to do the things that it does today in paper which is it underpins the economy so the
|
||||
good you know money exists because the government says so
|
||||
|
||||
businesses exist because the government registers them and allows them to operate and the laws and so forth of the of the government allow commerce to occur but we have no way of doing that in the digital economy right now there's no business models in the digital economy other than basically buying stuff and getting your data exploited for advertising so if you have a Visa card you're in otherwise there's no other really interesting transactions going on and I think big part of that is because we don't have any way of extending the trust of government into the digital realm in a way that is
|
||||
trustworthy
|
||||
|
||||
<img src="http://i.imgur.com/BVVoGaA.png"/>
|
||||
|
||||
so we're going to talk about that this is our fun slide this is where we're from Canada with a variety of animals quite a lot of space we come from Victoria BC I norm I actually grew up in Ottawa which is around the beaver and people think that's kind of humorous but so there you go that's her that's
|
||||
her
|
||||
|
||||
<img src="http://i.imgur.com/UN0dT5b.png"/>
|
||||
|
||||
I also want to acknowledge that I do all this work I do I do with Carol Prest who is the registrar for BCS so I've been there for a couple years and from day one we've been working together exploring how can we use the registry data as the foundational data for doing business and unfortunately she's not available she's in India right now but having this business partnership and having her in her organization behind this and having the discipline of trying to solve problems for businesspeople is what is making this project I think really fun and also useful
|
||||
|
||||
<img src="http://i.imgur.com/MrIep94.png"/>
|
||||
|
||||
so we're gonna focus on a problem here which is how do we help
|
||||
small business we have sort of a an example of Mary's bakery but it could be any kind of business construction mining whatever it is and the problem is that these business people are very excited about starting a business is an exciting time in life but they don't realize sometimes that they have quite a lot of obligations that they must fill for government
|
||||
|
||||
so we have examples where our research teams have gone out and talked to restauranteurs and they have released a building and so forth it's the perfect spot everything is great and then they realize oh I've got six months of permits and licenses to do because we had to bring it up to building code and they didn't realize this and then there's all these dependencies and they weren't ready to fund that building for six months so those are like real stories we'd like to try and minimize that kind of stuff because we want them to start their businesses and grow
|
||||
|
||||
<img src="http://i.imgur.com/FxeKL2D.png"/>
|
||||
|
||||
you know the path is also very meandering and it can be in multiple different media you can be faxing you could be email you could be online you're in person and so forth and so all of this is a very difficult yeah both for the business people but also on the government side we are also in different places verifying data all the time who are you what business we representing or you authorized to represent the businesses
|
||||
|
||||
<img src="http://i.imgur.com/sIiI6Ni.png"/>
|
||||
|
||||
in the most complicated cases for like liquor and so forth shareholders and employees have criminal background checks they make sure that nobody owns more than 8 stores that sells liquor and so forth and so on so I can take up to a year so
|
||||
|
||||
<img src="http://i.imgur.com/GM9FxgX.png"/>
|
||||
|
||||
what do we do well one of the things we're doing is we're collaborating with our peers and a couple of other jurisdictions so we're working with a team in Ontario and a
|
||||
team in the Government of Canada where I used to work the procurement agency and
|
||||
|
||||
<img src="http://i.imgur.com/oPuhVyP.png"/>
|
||||
|
||||
when we say working together we're actually writing code together there's no mo use no steering committees no work groups they have a couple devs and the business person we have a couple of devs in a business person we sprint together write code all this stuff we're going to show you today has been co-developed and significant portions have been done by each of the groups this is the journey that we'd like to enable
|
||||
|
||||
<img src="http://i.imgur.com/0MS4yEs.png">
|
||||
|
||||
it's a journey that we know well government gives you something you take that something to another institution you use it to prove something and you get and you get the outcome
|
||||
|
||||
so in this case it's the incorporation information that's given to Mary she goes to the bank and she can open a bank account turns out that that's a very general pattern and this is the pattern that we see in the sort of verifiable credentials realm
|
||||
|
||||
<img src="http://i.imgur.com/FNpnmLg.png"/>
|
||||
|
||||
so we have this pattern of holder which is a person or a business but a business can't really hold something on their own. so they have to have people holding it on behalf of the business, they presented to a verifier which is earlier in the sort of workflow they have to decide you know verifier says bring your list of things in and prove prove to me who you are and you have various permits and license and so forth
|
||||
|
||||
at that point you then to get to enter their form which is usually not that Pleasant go through a process and then you are issued something which you hold and so this is the pattern that we're very familiar with
|
||||
|
||||
we're sitting with you know a wallet full of these things I have bank cards and identity cards and so forth and we're gonna explore how we can do that so when we discovered that we were pretty excited it was about a year ago that we stumbled across Hyperledger Indy after having done a little bit of work with fabric and you know
|
||||
|
||||
so it was just Stephen and I on the team and we thought you know if it looked promising that there was this pattern here we could solve some of these hard problems we've been working on for years but we realized we didn't have any of these software for these different organizations or people
|
||||
|
||||
<img src="http://i.imgur.com/hHn9SLm.png"/>
|
||||
|
||||
somebody mentioned it this morning that the classic chicken and egg problem we don't have any software out there that we can issue to our issuers don't have software to issue and so forth but so we had a we had an idea actually we we realized actually in this case government is a little bit special which I don't like to say very often but
|
||||
|
||||
it turns out our core business is issuing that's what we do every service we have is pretty much an issuer so we thought hmmm what if we what if we could give the services that we are dealing with in the business realm somewhere to issue to
|
||||
|
||||
<img src="http://i.imgur.com/9IHbEkL.png"/>
|
||||
|
||||
we we had purposely picked business realm because if we're dealing with business data we're not triggering all the personal identifiable information problems. In the BC we call it fight by the Freedom of Information Act and Privacy Protection Act. When you get into personal data, of course it triggers all of that which is good but makes it very complicated to play with new technologies
|
||||
|
||||
<img src="http://i.imgur.com/6KxuQM9.png"/>
|
||||
|
||||
so we just dealing with open business data right now and we thought: what if we could create something where these issuers could issue data to? and it would be a public thing, and we call that **The Org Book**
|
||||
|
||||
so this is a bootstrapping technique that we're copying from Facebook. We're just playing with one side of the market. We're gonna deal with the supply side: the issuers of credentials, more commonly known as permits and licenses.
|
||||
|
||||
<img src="http://i.imgur.com/o5KphnK.png"/>
|
||||
|
||||
and because they're public and because they're open we can create this directory of searchable verifiable data and we can build software for the issuers
|
||||
|
||||
So our goal was how can we make it as easy as possible for existing services to be able to issue their credentials to this OrgBook starting with the foundational data of the registry, and we're going to show you that.
|
||||
|
||||
When we started writing this code built on top of Hyperledger Indy we realized that there could be intermediate benefits.
|
||||
|
||||
<img src="http://i.imgur.com/voKqoaF.png"/>
|
||||
|
||||
so first there's some public good and the searching and finding of data will show you that but it turns out we can also create api's and so forth to allow that data be searchable and we created an enterprise agent, for services to be able to verify the data in The Org Book
|
||||
|
||||
issue it so later when businesses have their own services for holding verifiable credentials, our issuers are ready
|
||||
|
||||
<img src="http://i.imgur.com/AdYRiK9.png"/>
|
||||
|
||||
so now I'm gonna hand it over to Stephen I'm gonna drive now am I that working okay so we'll show I can look here that's good so this is what The Org Book looks like in British Columbia so there's two instances and we'll show you them both but this is the British Columbia Org book and it's basically a kind of a Yelp type site
|
||||
|
||||
<img src="http://i.imgur.com/3WJsovF.png"/>
|
||||
|
||||
**we've got five hundred twenty-five thousand active legal entities in British Columbia every one of them has a record in here** they have the credentials that the registries have issued to them
|
||||
|
||||
<img src="http://i.imgur.com/obt8orK.png"/>
|
||||
|
||||
so let's do a search we're into chocolate because we're in Switzerland so we'll talk about a Isla Vancouver Island chocolatier so Purdy's chocolates so we can take a look at them so search capability names we've got other capabilities for what searches we can provide ways to filter and things but when we get into it we can see some information that the registry publishes so previously registered
|
||||
|
||||
<img src="http://i.imgur.com/lZdyMdh.png"/>
|
||||
|
||||
this is all public data this is all open data this is exactly what they hang on their walls inside the restaurant and things like that there's really no place in BC it is actually published but in a very obscure place very difficult to find so we've actually as a byproduct of doing this exercise created a pretty useful facility for citizens to use to find businesses so we can take a look at them
|
||||
|
||||
<img src="http://i.imgur.com/D7lPViK.png"/>
|
||||
|
||||
this one has a couple of credentials they actually have a corporate entity and then a couple of names they do business under so they've got several credentials we can see a timeline of when they've got the different credentials so we can take a look at those in it and as the history builds up we haven't loaded all the history of all BC companies yet some of that is on paper which is going to be more challenging but that's that's not for us to worry about but we can load them up so if we can look at our registration we can see an active credential
|
||||
|
||||
<img src="http://i.imgur.com/IJIhLer.png"/>
|
||||
|
||||
so this is what a credential looks like online basically we present it with the key data that a person might be interested in and then at the bottom we can actually go into the credential from an Hyperledger Indy perspective
|
||||
|
||||
<img src="http://i.imgur.com/FYuqYtD.png"/>
|
||||
|
||||
so this is the schema if you as they call it on the one side the populated data for this particular version of the
|
||||
credential and then down below we get some really fun stuff
|
||||
|
||||
this allows any citizen to go and do the cryptography on
|
||||
paper themselves to prove that this is a proven credential yeah and we say verified see the check up there that's
|
||||
the that's the key
|
||||
|
||||
<img src="http://i.imgur.com/47eUSiL.png"/>
|
||||
|
||||
okay I think that's most of what we wanted to show so the idea here that we wanted to talk about a little bit was the title of this, **this is a production system, we've been live since the 10th of September**
|
||||
|
||||
<img src="http://i.imgur.com/cHws3Sb.png"/>
|
||||
|
||||
there's a little story there so let's go back to the home page and let me talk about a couple of things there the current statistics those are actual statistics we actually recreated the credentials and loaded them this week
|
||||
|
||||
so that's why **2.6 million were issued this week** we can do that the first weekend in September when we loaded it, it took 10 days to load the credentials so that kind of wasn't too good.
|
||||
|
||||
**we had Ontario coming behind us with about five times as many credentials** so we were a little nervous and did a couple of sprints to scale up its capabilities
|
||||
|
||||
BCGov, which has [the developers exchange](https://bcdevexchange.org/), is a pretty progressive environment for developing code. We've got an open shift kubernetes based platform
|
||||
|
||||
so basically we were able to use the capabilities of that platform to just spin up other instances and be able to scale up the the speed of loading and things like that so we got up to
|
||||
|
||||
we're now about 12 hours to load the full data set so we're creating issuing and holding about 2600 credentials per minute so decent speed it's kind of weird because we are a single holder for all of these organizations these don't the organizations don't have their own wallet and the first vision and the first thing that Indy wanted to support was the idea of a person having a wallet
|
||||
|
||||
so the database behind it was not the most scalable solution out of the box so the next thing we did as well to to make it scalable was to implement say an enterprise-grade wallet with Postgres in was the developer on that and we were pleased that yesterday his code was merged into the Indy SDK repo so it's now officially hyper ledger code which is kind of cool so that's a contribution we've made to the to the ecosystem in hyper nature Indy
|
||||
|
||||
<img src="http://i.imgur.com/rrQSzsd.png"/>
|
||||
|
||||
yep so the next piece that I want to talk about where's the search so one of the things you're seeing is this is a BC site but it's really very generic so what we've tried to do is make it completely agnostic of what the actual credentials that will be loaded in
|
||||
|
||||
we do have the concept that it's a an organization so we've got names we have addresses the concept of addresses we have the concept of credential types we have the concept of dates in there but other than that the structure is whatever the issuer happens to issue so it's very flexible for others to use
|
||||
|
||||
<img src="http://i.imgur.com/sewb1Aq.png">
|
||||
|
||||
so that search that's up there is you know it was a decent amount of work uses solar and and and so on but is very generic so that other entities other jurisdictions can take this and basically spin up their own instance of this relatively easily using this code and be able to take advantage of the loading the naming the searching the display all of this is flexible and localized localizable
|
||||
|
||||
|
||||
<img src="http://i.imgur.com/LhbUVx9.png"/>
|
||||
|
||||
let's take a look at the Ontario one so The Ontario Org Book looks quite different from BCS obviously the search panel is the same they have different things they want to show and what they they don't want to show
|
||||
|
||||
<img src="http://i.imgur.com/wfCQNDT.png"/>
|
||||
|
||||
so for example in Ontario they didn't want to show the structure of a company they actually have a contract that charges for that so they weren't able to do that through this
|
||||
|
||||
so every entity and every doing business as is a separate entity on this so because we were building with multiple jurisdictions in mind right
|
||||
|
||||
<img src="http://i.imgur.com/L97WeSB.png"/>
|
||||
|
||||
from the start we've we built it to be pretty flexible and so you're able to construct it on your own have your own skinning language support there's multiple language support is in there built in already I think those were the main things got the list what's that yeah so
|
||||
|
||||
<img src="http://i.imgur.com/dajxVoN.png"/>
|
||||
|
||||
the two more things that I wanted to touch on **come to our workshop on Friday and Saturday** and what we're actually doing is building out issuers and verifier so this is the org book the central piece
|
||||
|
||||
<img src="http://i.imgur.com/lc9jCF1.png"/>
|
||||
|
||||
but what really is important is there's an API behind all this that a issuer of permits can use to learn about the company to fetch the credentials that are already there and have them proven and then issue credentials back to the org book
|
||||
|
||||
so a key part of this is that being easily able to extend this to many more permits and licensing providers could be within the government which we're working with
|
||||
|
||||
<img src="http://i.imgur.com/pFERRuw.png"/>
|
||||
|
||||
almost every project team we talked to says "oh we can use that!" so we're building that out and trying to make that as easy as possible so our workshop on Friday involves building an issue or verifier and actually deploying it out so you can create your issue your own credentials
|
||||
|
||||
<img src="http://i.imgur.com/QyOUf4G.png"/>
|
||||
|
||||
the other side of it that we think is going to be really important is well this is a bootstrapping mechanism we've realized there can be some life to this in that we're going to create we're going to be creating a pub sub subscription service basically so that a business that gets a credential and verifies it can subscribe to that credential in the future and get notified when it changes
|
||||
|
||||
so a big challenge in all government organizations is this ability to understand when things change and we think this can be a super light way for a business to get notified that:
|
||||
|
||||
"hey these two businesses just merged they've started a new entity", "those two entities no longer exist they've been dissolved in this new entity exists you should know that" and
|
||||
|
||||
so that webhook capability will just whatever you're subscribed to when when our credential changes we can notify you that it happened and then you can dig in to figure out how that affects your permit and licensing service the other piece that we'll show is thing called decentralized flow dFlow
|
||||
|
||||
<img src="http://i.imgur.com/a8WzejN.png"/>
|
||||
|
||||
so do you wanna go to that okay spicy wings we're gonna look at spicy ways so this is our dev site so where this is just new that we're playing with so this is a company that's got four different credentials from different organizations
|
||||
|
||||
<img src="http://i.imgur.com/jUyJEIk.png"/>
|
||||
|
||||
they've got a registration a PST that's a tax number from the province a clearance letter for workman's compensation for a worker's insurance and a business license from a from an entity from a municipality
|
||||
|
||||
<img src="http://i.imgur.com/mFfIzCY.png"/>
|
||||
|
||||
so with dFlow what we can do is basically what you're saying is I have a goal as a businessman I have a goal that I want a business license in the city of Surrey and it's going to be for a restaurant what have I got to do to accomplish that what other things do I need and
|
||||
|
||||
<img src="http://i.imgur.com/YSIIWLQ.png"/>
|
||||
|
||||
what we've built here is a dynamic workflow that starts with the one you want I want a business license and sort of says oh what are the prerequisites for getting a business license well that's been encaptured in the proof requests that the business requires before it will issue you the credential that they have to offer
|
||||
|
||||
<img src="http://i.imgur.com/PpzN2E9.png"/>
|
||||
|
||||
so we can look at that proof require and then iteratively go back to that proof request and walk back a step and walk back a step all the way back until we get to the starting point and
|
||||
|
||||
<img src="http://i.imgur.com/XQK4hH3.png"/>
|
||||
|
||||
now we can display dynamically what does that company need in order to get a business licencse there their goal and then what have they already got that allows them to proceed
|
||||
|
||||
<img src="http://i.imgur.com/FvA5vMU.png"/>
|
||||
|
||||
so basically this company the ones in blue they already have and they can take a look at it the ones in yellow they're able to acquire now because they have all the prerequisites they haven't got it yet but they have the prerequisites for it and the ones in red they don't have the prerequisites they're just going to get rejected so no need to start in on those already
|
||||
|
||||
<img src="http://i.imgur.com/Pmtg8km.png"/>
|
||||
|
||||
the nice thing about this is all of these entities that are issuing credentials that are issuing permits and licenses don't have to know the whole journey that that's really hard to figure out all they have to know is what their prerequisites are and as soon as they express those in the form of a proof request we can dynamically walk that chain and figure out what what else they need compare that with what's in their wallet what credentials they already have and now we can give them a picture of where they are all right if we got a minute
|
||||
|
||||
<img src="http://i.imgur.com/ZdQrDU3.png"/>
|
||||
|
||||
one of the things we're going to do in the workshop is in spinning up your issue or verifier is you'll have to connect to and create ended transactions on Indy blockchain on a distributed ledger
|
||||
|
||||
so this is a tool we created to be able to browse the network so we can look at in this case the four node network that we've got running we can look at the status of it
|
||||
|
||||
we can do some operations like look at the Genesis transaction but we can also dig in and look at what are the transactions that actually exist on the ledger at this time
|
||||
|
||||
<img src="http://i.imgur.com/J6I6GkD.png"/>
|
||||
|
||||
we can do some searching for things and find all the ones that have tax in the name we can search by types of in this case we're looking for schema
|
||||
|
||||
<img src="http://i.imgur.com/QfgNVr1.png"/>
|
||||
|
||||
so this gives you a really good way of actually being able to see what is on the ledger you know get an idea as you register an issue or verifier take a look at what's there
|
||||
|
||||
so that's kind of a preview of the site and the ideas that have been emerging as a result of our work but there's a little bit more
|
||||
|
||||
<img src="http://i.imgur.com/8tyRlCK.png"/>
|
||||
|
||||
one of the things that we're trying to do is, it's helpful for BC businesses but BC businesses do business all around the world and we want our businesses to be able to interact digitally with everybody else and like Steven mentioned it's not just businesses but it's professionals and so forth and so on
|
||||
|
||||
this model could work for professional engineering societies medical societies other kinds of things that have public accreditation that you need to check on
|
||||
|
||||
<img src="http://i.imgur.com/3O2CKLa.png"/>
|
||||
|
||||
so we have this idea where we think The Org Book helps us establish our local neighborhood. businesses are gaining their credentials and and that's kind of building up our local ecosystem
|
||||
|
||||
<img src="http://i.imgur.com/aYIYVha.png"/>
|
||||
|
||||
that makes it easier for us to help them find their way like we just demonstrated because each of these issuers are going to automatically be able to express digitally the preconditions that are necessary for them to be able to allow you into their service and an issue a new permit
|
||||
|
||||
so we think that's pretty pretty cool and as a result of this learning we've we've come up with this generalized model that has been accepted as a sub project of Indy so we're calling that Indy catalyst because
|
||||
|
||||
this is sort of a bootstrapping capability and that'll comprised of the code-behind The Org Book in a more generalized fashion and the code behind the issuer verifier service that we've built which we call von X but we'll give some other sub named as an indie catalyst component and
|
||||
|
||||
the big reason behind this is because I work for the government of BC, we're not a software development agency, were serving the public and
|
||||
|
||||
also we want this to be part of a global capability and
|
||||
having a sustainable set of software know in a you know well governed organization like the hyper ledger Linux Foundation we think is a good way to go and so
|
||||
|
||||
we think that has over time these neighborhoods as they grow hopefully well beacon will create what we call the verifiable organization Network
|
||||
|
||||
so this is sort of a concept where if you can use these kinds of tools and it doesn't have to be Hyperledger Indy it could be any system that is decentralized identifier—verifiable credential compliant
|
||||
|
||||
you'll be able to exchange verifiable data amongst businesses and that is really what we want to be able to do it's nice that they could come and do business with us like get the things they need but what's really more important is it that they transact amongst themselves that's what the economy lives so that's the idea of
|
||||
|
||||
The Verifiable Organisation Network and the coming code that we'll call a Hyperledger Indy Catalyst so that is our
|
||||
talk for now
|
||||
|
||||
as Steven mentioned **we're having a workshop Friday and Saturday morning** and Ian and Steven and I'll do my best to help will walk you through actually creating an issue we're
|
||||
creating schemas and and and doing your own decentralized workflow example
|
||||
|
||||
we're happy to take questions if there are any yes I think I think it's controlled by the center there hello okay just wanted to check any pre requests for the workshop any required software any comments you
|
||||
|
||||
just be installed before hand you need a browser and you need a docker hub ID but you know you could do that while you're there yeah so the prerequisites are a docker hub ID and then everything else can be done in a browser and we'll just we've got all the guidance and so on but you don't need anything else I don't think about Chrome is ideal right chrome is probably the best we're using a tool called play with docker so you don't have to install anything on your machine it's super cool I promise no biometrics No
|
||||
|
||||
so you did mention the verifiable claim and you you implied standards and I just want to confirm with the audience here because we had a side discussion.
|
||||
|
||||
it's w3c compliant verifiable claims and then and so I don't want to ask about the the other adjuncts that the registrar and the verifier because you talk about those concepts but I'm trying to understand what standards you use or what you're developing on your own and what standards apply specifically the registrar right so right now it's Hyperledger Indy version of things but as they progress they'll they'll create the ID doc specs and the end verifiable credential base
|
||||
|
||||
but that's still emerging right in terms of how the agents communicate we're actually contributing quite a bit
|
||||
to sort of this agent agent protocol and that's being done in the open as well right now in this sort of Hyperledger
|
||||
Indy working groups but we want interoperability
|
||||
|
||||
we'd like our citizens to have a choice so they could use a DID method of their choice they could use software of their choice when it gets to personal data or this data we think if that's where the marketplace will provide options for citizens and businesses like the holder software so whatever standards emerge we would want to support those and we're helping shape some of those as well so
|
||||
|
||||
there isn't a specific standard for the agent agent protocol but it's a collaboration with the decentralized identity foundation and the w3c folks and the hyper ledger folks yeah one of the things we thought about as John alluded to early in the talk was oh we're gonna build this thing in our organizations they're gonna use our agent and they're gonna talk to our issuers and verifiers and we're gonna build all that stuff and then we realize no this is not what we should be doing we shouldn't be in the business of doing that we need to be in the business of issuing credentials
|
||||
|
||||
so we have to build software for that we need to make do it in a way that allows them to change as little as they need to we don't want them to have to read recreate their world we want them to just be an adjunct on just like they use a printer to print the verified credential the permit or the license so they can hang it on the wall we just want them to stamp out a digital version of that that's signed cryptographically right and
|
||||
|
||||
one of the things I say about that is like so this piece of software that we've been we sort of we take it for granted now but everything we've done is in the open every line of code every presentation every ticket it's all in github so it's all patchy
|
||||
|
||||
I mentioned we're contributing to the Hyperledger thing but sort of a line I say is like if your system can produce a CSV of your permit or license data then you're in our box we'll take care of the rest
|
||||
|
||||
you'll learn on the workshop that it's just an hour to to configure that thing to make it work for you and and that's how much work it takes kind of thing
|
||||
|
||||
we're trying to make it as easy as possible because we're from government we know like it's basically impossible to do IT things so we wanted to like you know make that as simple as possible
|
||||
|
||||
you have the concept of in this case the org book is the wallet right, and the issuers issued to it but it'll be using the same protocols in the future to issue two individual wallets which is the demand side right that sort of goes closely to the question I was going to ask
|
||||
|
||||
which is one of the points of blockchain is usually to have nodes under control of multiple entities where are the actual nodes right now from what I understand they're all under the control of the BC government so could there be like variances like an NGO holding onto one of the nodes, the production systems using the sovereign network to store the DID
|
||||
|
||||
there's a DID and a schema and a clerk read that you know credential definition and yeah on there but again in theory that could be another DID Network it's just there
|
||||
aren't any other DID networks
|
||||
|
||||
so we're not gonna run the network we don't want to be running node but we're not running the network um the the thing you remember with verifiable credentials is they don't go on the ledger so none of the data about the organization's or about individuals goes on the ledger it all goes into a wallet
|
||||
|
||||
the weird thing we are doing is we've got this community wallet concept but once people have their own wallet we'll be issuing to their wallet directly we won't we may continue to issue to our own community wallet but for public credentials but for any other for the credentials once they have a wallet will be issuing to that wallet and they will be able to use it wherever they need to use it in whatever jurisdiction has systems that allow it
|
||||
|
||||
we are doing some collaboration with some folks from spark Telecom New Zealand that have a pretty nice implementation and we're using that as an opportunity to develop the early version of the agent agent protocol that's generalized
|
||||
|
||||
so as soon as we get code that map we had originally that just had Ontario and and Ottawa on it will expand to include New Zealand so we're looking forward to that and others
|
||||
|
||||
the schema you used for business registration is something that came from a standard about business registration or Ontario's doing the same one so that you guys just like get together in a darkroom and created or New Zealand I mean what happens with that
|
||||
|
||||
it's a schema that we co-created with Canada and Ontario
|
||||
but we also looked at like standards in Canada that have evolved like I've been in this business for very it's not an ISO no no no there isn't such a thing in the world for that for businesses other than like maybe schema.org but it's
|
||||
really not sufficient yeah so we evolved it together and so far
|
||||
it's working you know
|
||||
|
||||
it's a bit tricky to get the minimal set but but again this helped with having multiple jurisdictions involved so we had a first, we did Ontario and we went wait this isn't gonna work we don't want that we're both Canadian entities we should be able to figure that out and that worked pretty well and then the other side of it was
|
||||
|
||||
once we got into things like the the doing business as well that's totally uncharted territory no not really yeah been done and we came up with something, Ontario came up with something even better, and we balance back and forth to figure out what a real
|
||||
|
||||
it's actually a relationship credential so we can have it point both ways the interesting thing there the thought process was a lot around we originally started oh you know how is The Org Book gonna show this and all that then we realized no that's not the right thinking what the thinking is is what is the business gonna want to do with this
|
||||
|
||||
what do they have to prove to somebody else and that's how you look at how how to build a credential is you stick it in the wallet of a business in this case or a person and figure out okay they've got to prove this to show that they're a
|
||||
partnership to the bank how are they gonna do that and
|
||||
|
||||
that's the sort of mindset we had in building credentials so we built this so that's where the relationship credential came from which is I was very happy about because it's basically the edge in a graph so I'm terminal like that idea
|
||||
|
||||
the registration credentials are the nodes and this is a credential that demonstrates a linkage between the nodes of a knowning doing businesses name but that that those labels could be changed to is a director or as a beneficiary or any kind of relationship can be modeled this way between two things and so that generalizes the model to basically whatever you want which also gives it interesting properties in terms of visualization and analysis and relationship recommendation engines and that kind of stuff so it was fun hospital systems
|
||||
|
||||
we're gonna be talking with man Revere you know that's what an interesting thing is that you know like if you look at you know College of Physicians and Surgeons and other kind of public statements my you know engineering societies they publish these things already so they could have a version of this and then that just becomes part of the overall ecosystem so that you can for example have a prescription issued by a doctor to patient that patient brings the prescription to a pharmacy the pharmacy asks proof but at the same time can look at that credential say oh I'm gonna look up that doctor in this in the public you know verify in public doc hub or whatever the heck they call it and and they can subscribe to those things too so they can always know if that doctor currently licensed maybe that doctor has a restriction on the kinds of things they can prescribe so I think it's like it's a it's complementary to the peer-to-peer transaction when you have these public sort of hubs of trusted data we don't have them loaded today now like you come to the workshop we could
|
||||
build another interesting one we're looking at is evident evidence so another function and the provincial
|
||||
government is mining inspections things
|
||||
like this so inspectors go out into the field out like offline and they are recording videos taking pictures making
|
||||
notes and so forth and they would like to be able to be used data that they gather five you ten years from now and
|
||||
be able to answer the question definitively it was this person using this device on this place at this time
|
||||
and it data was unaltered well that's a credential you could have their phone issue a credential to an internal hub of
|
||||
like this and you know ten years from now when there's a court case they can use that you can just ask for a proof
|
||||
from it and at that point we know that it's unaltered and and we know who it was and we know what version it was and
|
||||
what chunk of binary data was hashed in there
|
||||
so we had to experiment with that that could be quite an interesting matter all right we're just about done any other
|
||||
questions or great well hopefully some of you will come for a workshop and thanks for your time
|
||||
