Holder initiated Presentations

[mixmix]

Proposed feature

For our use-case in Ahau, we want presentations to be part of our Tribe Registration process. We have secure end-points (public keys you can encrypt messages to) where it is safe to send messages to Kaitiaki (custodians/ guardians/ admins of a Tribe).

Here:

• our applicant is a VC holder, and
• our kaitiaki is a VC Verifier (they want to know more about the applicant)

At the moment we have an slightly annoying workflow which goes:

1. applicant sends registration
2. kaitiaki (later) sees registration (status: "awaiting VCs"), and sends an oob-connection to initiate presentation of a VC
3. applicant (later) sees oob-connection invite, accepts it
4. kaitiaki (later) sees connection is ready, and requests presentation
5. applicant (later) completes the presentation
6. kaitiaki (later) sees the registration (status: "VCs confirmed) and can approve the registration

Each of those steps could have significant delays. The applicant may be applying from their phone/ laptop, and the kaitiaki is maybe reviewing applications from their laptop. They are not assumed to be both online at the same time, so each asynchronous step could make significant hold-up for a process

Feature description

The steps we would prefer:

1. applicant sends in their registration, including an oob connection invite (signalling desire to present VCs)
2. kaitiaki (later) sees registration, completes connection, AND requests presentation
3. application (later) completes the presentation
4. kaitiaki (later) sees the registration (status: "VCs confirmed) and can approve the registration

Anything else?

NOTE: we use scuttlebutt messages to communicate state-progression (which initiates actions) between the applicant (a Holder using the SDK) and the kaitiaki (Verifier, using a hosted Agent via https APIs)

update .... we're working on this now with a grant! First step is "Holder initiated connections"

@mixmix , so should this issue be assigned to you?

[mixmix]

@mkbreuningIOHK what does "assigned" mean in your org context? In orgs I've been in it means "is going to take this work on". It's unclear what sort of Open Source project this is at the moment - is Identus collaborating with outsiders, welcoming PRs, contributions to direction setting? If yes then those things would need resourcing - people and time on Identus side to weave others work in (I've been on the other side where we have under-resourced this and it's a bad time)

cc @elribonazo here is an example of me asking for more power at the "edge" (shift towards fully p2p agents)

Getting back to this to make some real progress.

On our most recent improvements we've included SDK to SDK verification through DIDS and didcomm. Also have integrated ConnectionLess flows.

Let's re-open this thread and try to make some progress. We still need to make Connectionless flows re-usable thats last thing i can think of right @mixmix ?

[mixmix]

Yes! @chereseeriepa and I have been working on getting the new SDK woven into Ahau. We have integrations tests passing, and it's beautiful! Next up from us:

• milestone reports showing what we've done
• documentation improvements for Identus
• PRs to improve some testing of these new features for Identus
