@iwTGBs

@mnzaki The application is "entirely and mostly" local first. At least for the purpose of authentication between wallet and frontend. Once the identity is logged-on to the frontend (which basically means that the user has demonstrated that he is in posession of the private key of the identity via the wallet and not some identity-impersonator), the frontend (which is the client UI and business logic) then is capable to log-on to a cloud service which provides the transactional data to be run/processed in the frontend client. Note : The identity (DID) needs to be pre-approved in the cloud-service by a separate permissioned process. Concerning taking a look at the source code: Yes, we will open-source the frontend in the future but its not yet done. Nevertheless we really would like to have a chat with you if it´s possible (Skype / Zoom or other means). For better mutual understanding of what we are doing ( Integration of your wallet) and regarding our requirements for your wallet for our next steps with our frontend / cloud-service.

@mnzaki Hey. Following Problem: with the Swimming Pool example. Redis server is running properly. BUT: Backend Server doesn´t start. Im checked out with "git checkout feature/aKaartIntegration" as described in the Documentation and am using that standard configuraiton without change. On console logging in "server.ts" it gives me the following error when i start the backend server manually(manually, because it doesn´t start it with yarn start). Hallo
SoftwareKeyProvider {

@chunningham

Hi @iwTGBs, this is caused by that branch using an older version of the library which uses a since-deprecated Infura API. To solve, I would recommend either using the master branch of the generic backend or upgrading your jolocom-lib dependency to 4.0.1. The master branch should still work for the swimming pool as long as you keep the same config.ts file, however some type definitions may have changed slightly, e.g.:

/* Credentials required during authentication */
export const currentCredentialRequirements = ['a-kaart']

export const credentialRequirements = {
  'a-kaart': {
    metadata: demoClaimsMetadata.akaart
  }
} as { [key: string]: ICredentialReqSection }

/* Credentials offered by the service. */
export const credentialOffers = {} as {
  [key: string]: {
    schema: BaseMetadata
    metadata: {
      renderInfo?: CredentialOfferRenderInfo
      metadata?: CredentialOfferMetadata
    }
  }
}

The main changes on the aKaartIntegration branch are related to integration with an external service via adding custom middleware, so it is still a good example of that.

Johannes

@iwTGBs

@chunningham i stayed on the akaart branch and updated the dependency to 4.0.1 keeping the config.ts as follows(in first snippet) and changing specified area to your new code example. He cant find CredentialOfferRenderInfo and CredentialOfferMetadata thus "yarn build " throws 8 errors.

Mina Nagy Zaki

@mnzaki

@iwTGBs that branch is really old, trust us on this one :D it's something for an old demo, and some things have changed since.
I think a more plausible solution would be to merge master into into it to get it up to date, if you really insist on using it
though a much better solution is as @chunningham outlined in https://gitter.im/jolocom/SmartWallet?at=5e56488cd7bb4e179ca1b614

Johannes

@iwTGBs

where do i find more documentation on how the backend is connected to qr code implementation / functionality?

Johannes

@iwTGBs

and/or could i get your avalon related backend configuration e.g. "config.ts" to understand it or the whole backend .tar file ;-P?

@agruener2000

Hi, on which Ethereum network is Jolocom connecting and creating the identities?

Johannes

@iwTGBs

@mnzaki after the wallet sends the POST request and the data the frontend requested to the backend, does the backend automatically send it back to the frontend ?

or do i have to configure the middleware route.ts or somth*?

Mina Nagy Zaki

@mnzaki

@agruener2000 hi! sorry for the very late reply......
We're on rinkeby network. You can find that information in the jolocom registry code: https://github.com/jolocom/jolo-did-method/blob/master/jolo-did-registry/ts/index.ts

Mina Nagy Zaki

@mnzaki

@iwTGBs it's not exactly automatic, there is some code to do that in the generic backend
Which flow are you implementing?

CredentialShare managed by https://github.com/jolocom/generic-backend/blob/master/src/controllers/registration.ts
or CredentialOffer managed by https://github.com/jolocom/generic-backend/blob/master/src/controllers/issuance.ts

In either case there is a point at which this happens: await setStatusDone(redis, nonce)

This is important because it triggers the code here to run: https://github.com/jolocom/generic-backend/blob/52765fdf15b8a5e9f840b269b927aa0eb477bac9/src/sockets.ts#L80
which will send data through the socket, and I think that's what you are missing!

This code is triggered by changes being made to redis (that's basically what watchDbForUpdate is for)

Johannes

@iwTGBs

which one of the two is used if Frontend requests email on authentification , as defined in config.ts with / Credentials required during authentication /
export const currentCredentialRequirements = ['email']. i assume thats the setting if an /authenticate/ get request comes in. wallet scans code and sends email to backend for pass to frontend . is that CredentialShare or CredentialOffer.

Mina Nagy Zaki

@mnzaki

That is actually for CredentialShareflow on the wallet, which is used in the controllers/registration.ts code.

Note that the backend code does not send any data or credentials back to the frontend after success!
You must do that manually if you want/need to.
The backend will only send a success message over the websocket

Johannes

@iwTGBs

The backend will only send a success message over the websocket
does it send that back to the Frontend? because in that case my Frontend doesnt even receive a success message while its listening.

Problem: Deep link to to Jolocom Wallet app fails.
Background: I wanted to use an service that was built a year ago and was running until x-mas without problems.
It is based on jolocom "jolocom-lib": "^3.0.0",

Meanwhile wallet creation fails with exeption.
Did the interface change?

const registry = JolocomLib.registries.jolocom.create();
        const vaultedKeyProvider = JolocomLib.KeyProvider.fromSeed(didSeed, this.password);
        registry.authenticate(
            vaultedKeyProvider,
            {derivationPath: JolocomLib.KeyTypes.jolocomIdentityKey, encryptionPass: this.password})
            .then((identityWallet) => {
                this.wallet = identityWallet;
            });

@joerasa

I tried Jolocom wallet 1.6 and 1.7. 1 and 1.8.0
The problem is with the wallet creation of the service not with the mobile phone

Mina Nagy Zaki

@mnzaki

Hello @joerasa!
Can you share the exception/error message you are getting?

if you haven't updated to jolocom-lib ^4.0.0 then normally nothing should have changed in a breaking way :D

There is no catch implemented if wallet creation fails. Therefore the exeption

Mina Nagy Zaki

@mnzaki

@joerasa can you please confirm the installed/running version of jolocom-lib? NOTE: I mean the actual version, not the dependency entry. You can check with something like:

grep version /buergeridentitaet/node_modules/jolocom-lib/package.json

Mina Nagy Zaki

@mnzaki

Also, what is in JolocomService.js:49 ?
Is that the code you shared above?? If not, then can you please share a snippet of code around that part in JolocomService.js?
it is a little unclear where that new Error("Wallet undefined") is being thrown.....

I've been tasked to explore Jolocom as a Self Sovereign Identity platform. Over the next few days, I'll be setting up the environment and building a prototype from the SDK. I'll be starting from https://github.com/jolocom/jolocom-lib, https://github.com/jolocom/jolocom-sdk, https://gitlab.com/jolocom/municipal-service, https://github.com/jolocom/generic-backend, and https://gitlab.com/jolocom/municipal-service. If there are any other starting points, please let me know.

If possible, I'll be more focused on creating a CLI tool compared to the UI parts.

@ChinmayPatel

Quick question, is there a comparison between Jolocom other SSI solutions?

Hello @ChinmayPatel !
Currently the most up to date demo would be using https://github.com/jolocom/generic-backend/tree/interaction-demo https://github.com/jolocom/generic-frontend/tree/interaction-demo
The demos are not integrated with the SDK yet (it's under development) Please join https://gitter.im/jolocom/jolocom-sdk for updates soon!

hello everyone
I am trying to setup a complete stack with the bare minimum I need to use jolocom with Smilo blockchain
I cloned the jolo-did-method, compiled it all, configured the truffle to deploy the smart contract to the smilo blockchain
then I cloned a old repo, demo-sso and now I am facing a issue that seems to be related to this

registry.authenticate(vaultedKeyProvider, {derivationPath: JolocomLib.KeyTypes.jolocomIdentityKey, encryptionPass: password})
.then(identityWallet => {
  configureRoutes(app, {setAsync, getAsync, delAsync}, identityWallet, password)
  configureSockets(server, identityWallet, password, new DbWatcher(getAsync), {getAsync, setAsync, delAsync})
})

it throws:

Demo service started, listening on port 9010
(node:329398) UnhandledPromiseRejectionWarning: Error: Could not retrieve DID Document. Returned error: project ID is required
    at JolocomRegistry.resolve (/opt/js/jolocom/demo-sso/node_modules/jolocom-lib/ts/registries/jolocomRegistry.ts:175:13)

I think that is because I am missing Where is your service deployed. E.g. https://demo-sso.jolocom.com
my question is, what is the service I have to have running local to pass over this err ?
is the generic backend ?
