Attendees
...
- DID usage, but not DIDComm adoption
- Custom DID implementations
April 2023 IIW
...
DIDComm v2 interop
- How can we get the word out?j
- Receive a credential over OIDC (OIDC4VC) and present proof with DIDComm
- Who in the OIDC to connect with? Also, connect with Sam. Ask Drummond.
- Which agents might participate:
- AFJ
- Ariel Gentile
- Animo?
- Veramo
- Nick
- Cody
- BlockTrust
- AviaryTech
- Indicio
- PicoAgents
- RootsID
- RootsWallet
- Atala Prism
- Alex Andrei Rodolfo Miranda
- Anyone from Atala team attending?
- AFJ
- What protocols do we want to highlight/use
- Basic Message
- Trust Ping
- Mediation
- Issue Credential
- This is more complex, which format, etc.
- Pre-record video showing the interop between them
- For the session it needs to be very scripted so that everyone is successful
- Group chat? New protocol, maybe in Fall IIW?
- For the session it needs to be very scripted so that everyone is successful
- Veramo agent as a test harness for DIDComm?
- BlockTrust is implementing mediator, etc and will be at IIW
- No usable .NET lib, had to write it from scratch
- Crypto is especially challenging
- Reference implementations help a lot
- SICPA libs continue to gain adoption and are nice for reference
- No usable .NET lib, had to write it from scratch
Interop Profile
- AIP3 hackmd table created to compare did peer/keri/key/ etc. pros/cons/needs
- Initial contact through OOB
- DID Doc should contain the endpoint which should establish the connection
Ecosystem of DIDCommV2 Services or local agents
- One other DCV2 agent required to work on true interop
- Plus one agent agnostic Technology Compatibility Kit (TCK)
- Nessus-tech domain service
DWN & KERI & DIDComm comparison
...
- Agents can cache DIDs to know if they have resolved the long-form, etc. This cache needs to be well protected or the conversation is lost.
- DIDComm provides a way to rotate Ephemeral DIDs, specifying a new DID (even from a different DID method).
From our last meeting:
Ecosystem of DIDCommV2 Services or local agents
- One other DCV2 agent required to work on true interop
- Plus one agent agnostic Technology Compatibility Kit (TCK)
- Nessus-tech domain service
Nessus
- Nessus DIDComm 23.2.0 First Release
- Wallet abstraction for AcaPy + Nessus native
- Camel Http Endpoint for Nessus agent
- Support for RFC0434 Out-of-Band Invitation V1 & V2
- Support for RFC0023 Did Exchange V1
- Support for RFC0048 Trust Ping V1 & V2
- Support for RFC0095 Basic Message V1 & V2
- CLI to work with supported protocols and model
- Uses SICPA and Walt.id
- Will eventually be wrapped in a Camel component, enabling Camel endpoints to support DIDCommV2
- open the doors for adoption from the Camel enterprises
- Nessus DIDComm 23.2.0 First Release
DIDComm v1 vs v2
- https://didcomm.org/book/v2/whatsnew
- simple explanation of the benefits of upgrading
- DIDComm v1 is tightly coupled to the Aries RFCs (encryption envelope) and v2 introduces some simplicity in terms of connections
AIP3
- HackMD from the last Aires WG meeting, regarding AIP 3.0
- Should we specify how the did methods (like did peer) are used?
- We are focused on DIDComm v2 communication but does the rest of the AIP community know that?
- WACI issuance
- Do you need to be able to resolve indy, cheqd, etc. in order to issue credential
- Discussed sub-roles https://raw.githubusercontent.com/hyperledger/aries-rfcs/main/features/0453-issue-credential-v2/credential-issuance.png
Aries Agent Test Harness
- What did methods are supported? And how do you configure to use did indy, orb, etc.
- What is the priority of tests to create that will eventually be AIP3 tagged tests?
- How is mediation tested?
- With the mediation role (what is the name like bob, alice, faber, etc) and show you support the mediation features.
Current DIDComm-V2 specific tests:
Code Block title DIDComm-V2 tests aries-agent-test-harness % ./manage tests --tags @DIDComm-V2 Selecting: ['@DIDComm-V2'] Feature: WACI Issuance @T001-IssueCredentialV3 @DIDComm-V2 - WACI issuance flow Feature: DIDComm V2 Establishing Connections @T001-OobV2 @DIDComm-V2 - Establish a connection between two agents using DIDComm V2 Feature: Aries agent present proof v3 @T001-PresentProofV3 @DIDComm-V2 - Present Proof of specific types and proof is acknowledged with a Citizenship credential type with a DID Exchange Connection
- New tag in AATH that are not credential related, maybe:
- DIDCommV2_Peer
- DIDCommV2_Simple
- Didcommv2_base
- Didcommv2_layer2
- See https://github.com/tdiesler/aries-agent-test-harness/tree/camel/aries-backchannels/camel#aip-10-status
Grand Unified Theory (GUT) Alliance
- There is a warning about did peer on the spec now https://identity.foundation/peer-did-method-spec/
- https://daniel-hardman.medium.com/sentries-confessionals-vaults-and-envelopes-4a58cf4f8a5a
- original did keri impl https://github.com/WebOfTrust/ietf-did-keri
- Needs to transition to a did keri lite (subset of did keri)
- Signify is a typescript impl that might serve as the the keri lite impl
- Newer than even AIP3.0. KERI and DIDComm v3.0 (likely)

- Apache Camel: https://camel.apache.org/ and we discussed Daniel Hardman's presentation to W3C that talks about classic API/Swagger Endpoints vs. a DIDComm connected ecosystem https://youtu.be/TBxWgNmsnvU
- Our current spreadsheet https://docs.google.com/spreadsheets/d/15noWiG_zhhUpornhrZm9cLEjQ1aa6z9qgJgPCaaIbtY/edit?usp=sharing
- AIP3
- HackMD from the last Aires WG meeting, regarding AIP 3.0
- Great document by Hakan, looking at past AIP definitions and beginning to consider AIP3 definition
- Connectionless DIDComm v2 still needs management of the 'connection' between agents. How should agents handle this?
- Is this worth detailing/discussing or is it just agent specific?
- OOB/handshake/discovery RFP for Aries agents?
- WACI and what the overlap and distinction would be between the AIP and WACI.
- There is some nuance to cred formats you have to support (Indy, BBS+, LD).
- Can we use Discovery protocol to understand the level of WACI support?
- perhaps we need more detailed information from the discovery protocol
- per application protocol supported (formats, messages, crypto).
- Some WACI information to consider https://identity.foundation/waci-presentation-exchange/#format-property.
- Encryption envelope selection
- WACI and what the overlap and distinction would be between the AIP and WACI.
- bruce_conrad@byu.edu is working with students to implement DIDComm v2 in their Pico environment. Might benefit from JFF work
- DIDComm v2 agent discoverability/interop
- Documentation in terms of Trust Over IP (ToIP) tech stack?
- ACA-PUG
- Libraries for message envelope (Askar, Python impl, Rust impl)
