| # Project Health | ||
|
|
||
| Hyperledger Aries is healthy, seeing lots of activity overall, especially in all | ||
| of the Aries communities, including [Aries Framework JavaScript], [Aries | ||
| Bifold] (mobile wallet), [Aries Cloud Agent Python], [Aries VCX] and [Aries | ||
| Framework Go]. Lots of progress being made on all of those efforts! | ||

||
| # Overall Activity in the Past Quarter | ||
|
|
||
| Per the [Aries Activity Dashboard] for the months of April-June 2023, Aries | ||
| codebases had 387 PRs (down 12%) from 70 contributors (down 13%). | ||
|
|
||
| [Aries Activity Dashboard]: https://insights.lfx.linuxfoundation.org/projects/hyperledger%2Faries/dashboard;subTab=technical?time=%7B%22from%22:%222023-04-01T07:00:00.000Z%22,%22type%22:%22absolute%22,%22to%22:%222023-06-30T07:00:00.000Z%22%7D | ||
|
|
||
| * There was a lot of activity towards integrating [Hyperledger | ||
| AnonCreds](https://github.com/hyperledger/anoncreds-rs) into all of the Aries | ||
| Frameworks to enable ledger-agnostic implementations, with the [Aries | ||
| Framework JavaScript] 0.4.0 as the biggest milestone. [Aries Framework | ||
| JavaScript] 0.4.0 includes Aries Askar and the shared components, including | ||
| [Hyperledger AnonCreds], fully integrated, and initial support for | ||
| [OpenID4VCs] protocols. | ||
| * [Aries Bifold] using AFJ 0.4.0 was deployed with ease, including updates | ||
| to existing Mobile Wallets being updated on the fly from using the Indy | ||
| SDK to using Askar. | ||
| * Instances of [Aries Framework JavaScript] using non-Indy ledgers were | ||
| deployed and being used. | ||
| * The [Aries Framework JavaScript] Team put on a workshop to cover all the | ||
| new capabilities in [Aries Framework JavaScript] 0.4.0. | ||
| * The move away from the [Indy SDK] accelerated over the quarter buoyed by the | ||
| knowledge of the improvements and fixes made in the [AnonCreds CL Signatures] | ||
| implementation now that it has been removed from Ursa and moved to AnonCreds. | ||
| Three of the four Aries implementations ([Aries Cloud Agent Python], [Aries | ||
| Framework JavaScript] and most recently, [Aries VCX]) have integrated the | ||
| shared components in place of the Indy SDK. [Aries Framework Go] has never | ||
| supported Indy ledgers. | ||
| * Motivated by the deprecation of the [Indy SDK], there was maintainer | ||
| engagement across three of the Aries implementations ([Aries Cloud Agent | ||
| Python], [Aries Framework JavaScript] and [Aries VCX]) to increase | ||
| reusability, maintain interoperability, and expand efforts at eliminating the | ||
| [Indy SDK]. | ||
| * A new repository — [aries-socketdock] — will be a key component of a fully scalable | ||
| Aries mediator deployment. The work by [Indicio] is a substantial improvement | ||
| over the current strategy for managing mediator to Mobile Wallet connections | ||
| using websockets. Next up is using [SocketDock] in a full mediator deployment. | ||
| * The Overlays Capture Architecture (OCA) Aries RFC (“[OCA for Aries]”) was merged | ||
| and deployment of the feature expanded to include its use in production apps. | ||

| ## Aries Framework Reports | ||
|
|
||
| ### [Aries VCX] | ||
|
|
||
| * Interop compatibility improvements | ||
| * Initial did-exchange implementation, working interop with aca-py | ||
| * Implementation of new components: | ||
| * `did_doc` - build and work DID documents | ||
| * `did_resolver` - infrastructure for resolving arbitrary did methods | ||
| * `did_parser` - parse and build DIDs | ||
| * `did_sov`, `did_web`, `did:peer` - did:sov, did:web, did:peer resolvers | ||
| * `indy_ledger_response_parser` - data model for indy ledger responses | ||
| * Complete transition for anoncreds operations from `libindy` to `credx` | ||
| * Additional features for indy-vdr integration | ||
| * Pluggable txn submitter (indy-vdr, indy-vdr-proxy, …) | ||
| * Pluggable txn response caching | ||
| * Pluggable txn signing | ||
| * 2 projects LFX mentorship program in progress: | ||
| * [aries-vcx based mediator service](https://wiki.hyperledger.org/display/INTERN/%5Bdraft%5D+Project+Plan+-+aries-vcx+based+message+mediator+service) | ||
| * [uniffi based mobile wrapper](https://wiki.hyperledger.org/pages/viewpage.action?pageId=98730187) | ||
|
|
||
| ### [Aries Framework JavaScript] | ||
|
|
||
| [Aries Framework JavaScript] release 0.4.0 was (as noted above) a major | ||
| milestone. The smooth deployment of AFJ 0.4.0 into [Aries Bifold] was | ||
| impressive, especially the seamless upgrade of Mobile Wallets from [Indy SDK ]to | ||
| [Aries Askar] storage. The addition of [OpenID4VCs] exchange protocols expands | ||
| the use cases for [Aries Framework JavaScript]. The maintainers of the [Aries | ||
| Framework JavaScript] library are looking to coordinate efforts to support the | ||
| EU’s [EUDI/ARF] efforts in at least [Aries Framework JavaScript] and, ideally, | ||
| all Aries implementations. | ||
|
|
||
| [EUDI/ARF]: https://digital-strategy.ec.europa.eu/en/library/european-digital-identity-architecture-and-reference-framework-outline#:~:text=On%203%20June%202021%2C%20the%20Commission%20adopted%20a,a%20set%20of%20common%20guidelines%20and%20best%20practice | ||
|
|
||
| ### [Aries Cloud Agent Python] | ||
|
|
||
| [Aries Cloud Agent Python] (ACA-Py) Release 0.9.0 was an important upgrade that changes the dependency on the now archived Hyperledger Ursa project to its updated, improved replacement, [AnonCreds CL Signatures]. ACA-Py users are strongly encouraged to use [Aries Askar] for all deployments, and to eliminate the use of the [Indy SDK]. An [Indy SDK to Askar migration document] has been added to the [aca-py.org] documentation site, and a deprecation warning added to the ACA-Py startup. | ||

|
|
||
| ### [Aries Framework Go] | ||
|
|
||
| There was a significant uptick in activity around [Aries Framework Go] this quarter. The focus has been on adding support for the proposed [SD-JWT] verifiable credential approach, as well as updates to the [DIF Presentation Exchange] implementation, and [VC Data Integrity Specification] handling. | ||
|
|
||
| [SD-JWT]: https://datatracker.ietf.org/doc/html/draft-fett-selective-disclosure-jwt | ||
| [DIF Presentation Exchange]: https://identity.foundation/presentation-exchange/ | ||
| [VC Data Integrity Specification]: https://w3c.github.io/vc-data-integrity/ | ||
|
|
||
| # Current Plans | ||
|
|
||
| * Completing the work on eliminating the use of the [Indy SDK] in favor of the | ||
| [Aries Askar]/[Indy VDR]/[Hyperledger AnonCreds] across frameworks and deployments of those | ||
| frameworks. | ||
| * Continued expansion of features in [Aries Bifold] mobile wallet apps, including building on | ||
| the wallet-to-wallet support added in Q1, and expanding support for OCA to | ||
| enable beautifully displayed credentials. | ||
| * Defining and executing a [Community Coordinated Update] to convert the use of [Unqualified DIDs to use `did:peer` DIDs]. | ||
| * Explore and implement features aligned with the [EUDI/ARF] guidelines. | ||
