#1

APAC:

Alex :

Way of identifying and fetching trust registries and trust registry entries using did urls.
Similar to service discovery.
Addressable Resources.
TRP might use did linked resources for identification.
- Alex: Created a way to reference any file which is stored on ledger or IPFS using a DID URL. FIts really nicely with TR. Common syntax for addressing trust registries.
- https://docs.cheqd.io/identity/guides/did-linked-resources
Presentation: 30 min required
Requirement Translation:
- TR to have a persistent and unique identifiable.
- TR SHOULD have historical versioning and be retrievable.
Drummond:
- RFC 2119 is really good language (and guidance) on requirements language: https://datatracker.ietf.org/doc/html/rfc2119

Drummond:

You know, it could be really cool for this TF to publish guidance on best practices for implementing a TR on:
- a) DNS (Jacques’ proposal)
- b) blockchain (Alex’s proposal)

Yes - Vint and Bob's work on TCP/IP was operational and deployed long before Paul and Jon conceived of the DNS in the 80s.

if we don't use DNS, then you need a single /etc/hosts file with everything in it, that's going back to 1980... ;)

20:07:57 From Scott Perry to Everyone:
I suggest we rename the Trust Registry Specification to Trust Registry Technical Specification which includes minimum governance. This opens the door for a Trust Registry Governance Specification to be built to complement when that is warranted.
20:08:31 From Neil Thomson to Everyone:
Protcols?    As suggested in another thread - there are 2 protocols: "consumer" (can I trust this Issuer) and "administrator" protocols (CRUD on TR entries)
20:09:29 From Sam Curren to Everyone:
Replying to "Protcols?

I think we should focus on the 'consumer' protocol. management protocols could be a reach goal, but also must remain optional. The only thing that MUST be fixed is the consumer side.
20:09:57 From Neil Thomson to Everyone:
Replying to "Protcols?    As sugges..."

+1 on pushing admin to the project "parking lot"
20:10:40 From Jacques Latour to Everyone:
ok, the trust registry API is reachable via a URI URL, like, https://trustregistry.ca/api/readsomething, so there's a domain name for the trust registry, the domain name is in the DNS, and that's part of the internet innerworkings. otherwise it would be https://213.12.54.23/api/readsomething ...
20:11:58 From Darrell O'Donnell to Everyone:
“Trust Tasks” as carried out “using a trust task protocol” is a goal. We don’t have any operating trust tasks in the wild.

The key here is that we need to get to concrete implementations of our specification.

The first and simplest will, IMO, be a RESTful API. That will support the Trust Registry Protocol Specification v2. Other implementations will exist.

20:14:05 From Darrell O'Donnell to Everyone:
There is a tension between the abstract (Actors or Roles) and simple (Issuer, Verifier, …). Great APIs that achieve large scale adoption are simple. The reason, in my view, is that developers are lazy and just want answers. Causing them to understand new mental frameworks leads to low adoption.
20:14:07 From Sam Curren to Everyone:
Replying to "ok, the trust regist..."

You don't necessarily need to 'trust' the DNS however, it can be a simple facilitation mechanism. I think DNS being used or not is fairly uninteresting.
20:14:33 From Drummond Reed to Everyone:

I also agree that an admin protocol is out of scope for V2. Possibly in scope for a future version (I would consider the admin operations to be a different trust task.)

20:14:57 From Mathieu Glaude to Everyone:
Protocol is an orchestration between “consumer” and “trust registry”. Once that’s done we can define the API based on trust task needs. Something like this is what should be expected in the protocol definition: https://github.com/hyperledger/aries-rfcs/blob/main/features/0037-present-proof/credential-presentation.png

Exactly. Developers who use the Trust Registry Protocol won’t have to know anything about the Trust Spanning Protocol.

We keep going into solutions, without talking about what the requirements are. We need to stick to, what requirements the solution needs to cover, then go into possible implementations.

I don't think that's quite right Drummond. Users of Trust Task Protocols think at the Trust Task Layer - Trust Registry Protcols are at that layer.

Interesting diagram from @Jacques L. Does a TR replace the Verifiable Data Registry (which must include the core VDR data)?
20:20:16 From Sam Curren to Everyone:
APIs are not a bad answer, but depends on how well we want to fit on top of the Trust Spanning Protocol.
20:20:24 From Darrell O'Donnell to Everyone:
Specification and Implementation are clearer terms. “protocol” is incredibly loaded.
20:20:31 From Jacques Latour to Everyone:
both, look at the preso, the DID is resolved in the VDR, and authenticated further in trust registry

You need somewhere to discover/resolve a DID. And you need somewhere to verify authoritativeness.

DID resolution is its own protocol.

20:23:09 From Sam Curren to Everyone:
The real question: Do we require the orchestration to happen on top of the Trust Spanning Protocol?

Reacted to "The real question: D..." with 👍
20:23:50 From Sam Curren to Everyone:
Replying to "@Sam why do you say ..."

Because the 'consumer' interaction with a Trust Registry is much simpler than credential exchange.    That protocol is much more complex than our needs.
20:24:24 From Drummond Reed to Everyone:
DNS is a protocol. SMTP is a protocol. We need to define a protocol.
20:24:39 From Jacques Latour to Everyone:
if it's a protocol, then it's something that runs on top of port 97 (example) on top of TCP, UDP or QUIC, and it's socket based protocol...

Great question. Needs to be part of the requirements collection. I’m not sure tbh.

20:26:16 From Darrell O'Donnell to Everyone:
Replying to "The real question: D..."

No. If we require TSP we have self-limited who/what can access the system. For real-world things - we have zero places to integrate. Our job, IMO, should be opposite. Hundreds or thousands (or more) registries already exist. Getting at them is utterly inconsistent.
20:26:33 From Jacques Latour to Everyone:
SMTP protocol (port 25) does name resolution via DNS (port 53)….
20:27:40 From Sam Curren to Everyone:
Replying to "The real question: D..."

Do we require one on the TSP, one via HTTP API?
20:27:52 From Andor Kesselman to Everyone:
Replying to "The real question: D..."

I’ve heard some people wanting to constrain the TSP work to ToIP stack. I think we need to put some thought into this. There’s a reason the TSP will provide additional support that may be really important.
20:28:06 From Mathieu Glaude to Everyone:

20:29:32 From Darrell O'Donnell to Everyone:
Replying to "The real question: D..."

@Andor - constraining TSP on ToIP stack makes sense to me. It is defiining something new. A new way to establish trust. It’s the opposite of the trust registry realm.
