Preparation:

In preparation for the hands-on lab portion of the workshop, we have a few steps we'd like you to do before the workshop begins. We're all going to be a using a deployment of an open source tool called Traction to provide an issuer/verifier agent to all of the workshop participants to use during (and for a few days after) our session on Wednesday. As well, you'll need to install an Aries Mobile wallet on your mobile device so that you can issue verifiable credentials to yourself, and you can subsequently request presentations of those verifiable credentials.

Don't have time to do this setup? That's fine -- we'll be walking through the labs and you can just watch -- it's up to you!

Here are the instructions for getting ready:

• To get Get a compatible Mobile Wallet to use during the Workshop, we suggest that you go to this page for information about the BC Wallet mobile app, and how to get it from the Apple and Android stores.use one of these:
  • BC Wallet from the Government of British Columbia
  • Orbit Wallet from Northern Block
  • There are other Aries mobile apps that you can use if you want, including the esatus Wallet, and the Lissi Wallet.
• Click here to create your own Traction Tenant Aries agent, then do the following:
  • Click "Make a Request", fill in the data, and click "Submit".
    • All the fields are required, but need not be accurately completed for this use of Traction--we don't need it and won't ever use it! Do fill in the "Tenant Name" with something useful as you will see it in your Wallet later.
  • Your new Traction Tenant's Wallet ID and Wallet Key will be displayed. SAVE THOSE IMMEDIATELY SO THAT YOU HAVE THEM TO ACCESS YOUR AGENT. You only get to see/save them once!
    • You will need those each time you open your Traction Tenant agent. Putting them into a Password Manager is a great idea!
    • We can't recover your Wallet ID and Wallet Key, so if you lose them you have to start the entire process again.
• Go back to the sign in page and log in to your Traction Tenant agent using the your Wallet ID/Key.
• Make your new Traction Tenant a verifiable credential issuer by:
  • Clicking on the "User" (folder icon) menu (top right), and choosing "Profile"
  • Activating the "Connect Tenant To Endorser" toggle
  • Activating the "Register a public DID" toggle.
  • You can return to your Profile page to see your Public DID when needed.
• Connect to your mobile Wallet app by:
  • Selecting on the left menu "Connections" and then "Invitations"
  • Click "Single Use Connection", give the connection an alias (maybe "My Own Wallet"), and click Submit.
  • Scan the resulting QR code with your activated BC Wallet (or other mobile Wallet app) and follow the prompts.
  • You may get a "This is taking a long time" message on your phone. If so, check the status in the "Connections" list of your Traction Tenant.Check the Traction Tenant menu item "Connections→Connections" see the status of your connection – it should be "active"

That's it -- you should be ready to go!

When the time comes for the lab during the workshop, you will need to log into your Traction Tenant (so make sure you have with your Wallet ID/Key), and use your BC Wallet , so have both readyapp.

See you on Wednesday!
