Uport for Quorum blokchain about specs

[mirceanis]

Thanks for asking.

1. Theoretically yes. As long as the blockchain is compatible with the ethereum virtual machine it should work.
   You would probably need to deploy an ethr-did-registry to your chain first.

2. Institutions can use uport-credentials directly to interact with the uPort ecosystem. However there's no fully built solution I can point to as an example.

We are building a multiplatform framework to allow you to manage Decentralized Identities and Verifiable Credentials. It is designed to work for end-user apps as well as enterprises/institutions.
It is designed to be compatible with multiple identity types and use the W3C specs for Verifiable Credentials. For this reason it's not fully compatible with the existing uPort ecosystem.

Thank you for reply

Can you please clarify more how can I use the uport-credentials and what is its specificity.
If possible, can you briefly describe the workflow for this use case?

I searched somewhere and found that I could create an identity for any organization using uPort AppManager.
Is there any relation between uport-credentials and uPort AppManager?

If you can clarify these points, I will be very thankful.

[mirceanis]

uport-credentials is a library that helps create and verify credentials exchanged in the uPort ecosystem.
There is a strong relationship between AppManager and uport-credentials.
When you register an app in AppManager you get back a configuration that can be used in uport-credentials(backend library) and uport-connect(frontend library)

That being said, I strongly suggest checking out DAF, the framework I mentioned earlier, since that will be our main focus coming up.
The existing uPort libraries, app and infrastructure are only maintained on a best-effort basis.

Thank you again for your clarification.
One last question, is the uport-credentials permit the creation of the identity for organizations (controller and proxy contract)

[mirceanis]

It is not.
uPort has moved away from the proxy-contract model to a lightweight identity called ethr-did that does not require blockchain interaction when it's created, only when updating.

This has several advantages:

• it is much more scalable
• easier onboarding as there is no longer a gas requirement
• cheaper(free) to generate distinct identities to be used with distinct apps therefore increasing privacy.
• identities are not enumerable (also a big boost to privacy)
