To better make sense of Sovrin and the flow of things, it would be nice to see architectural diagrams. For example, a component interaction diagram of client & node flow. This would help us to make sense of everything. Thanks!
Hi Anti - I think @danielh may have something that should work. I’ll give him a nudge.
Antti, thanks for your question. I’ll jump in here and see if I can provide a couple of diagrams that may help per your request.
In the first example listed below, this diagram represents how someone (an Identity Owner) could use Sovrin to securely log in to any site using a simple Sovrin client application on their smartphone with passwordless biometric authentication. Here, the identity owner would simply click the “Login with Sovrin” button listed on the website, whereby the site would then send a push notification to the owner’s smartphone via their Sovrin agent of choice, eliciting a fingerprint challenge to authenticate the user and log him/her into the website. This is all done securely, privately, using public and private keys to ensure the owner is indeed the correct identifier wishing to log in to the website.
In this second diagram, notice how an identity owner could easily establish a new connection to a given website in much the same way, either by way of scanning a QR code or via a URL that contains an onboarding token.
While simplified, these diagrams hopefully help show the relationships between Identity Owner, Current or New Connections, Owner Agents, and the Sovrin Network. If you haven’t already had the chance, we also highly recommend reviewing the Getting Started Guide, as well as The Technical Foundations of Sovrin for a full review of how these various components interact with one another.
Again - thank you for your post. We value your feedback and would love to hear if this is helpful to you.
@Brian In the first image,
How to understand the did identifier? This is not the DID I think. And there are two times’ search on the ledger,
one for agent endpoint and one for sovrin id? Why two search? In my opinion one search is enough, got the DID the to DID object. And you will get everything you need.
Does anyone have a software logical architecture diagram that illustrates essentially the same data flows as above but from a (prototypical) software component perspective? …Tx on the blockchain, services within a Sovrin/Indy node, off-chain storage, etc. etc. Best regards, Michael Herman (Toronto/Calgary/Seattle)
Please take a look at the INDY ARM (Indy/Sovrin Comprehensive Architecture Reference Model). This graphic also includes an answer to the proverbial question: What is a “DID”?
This is a Draft Document for Discussion Purposes. I will greatly appreciate your feedback - large or small.
