title: Interoperability of Self Sovereign Identity Systems
|
||
description: Interoperability is a fundamental property of tech systems that are generative and respect individual privacy and autonomy.
|
||
excerpt: >
|
||
Interoperability moves from theory to reality when companies have meaningful ability to choose. It is predicated on open standards foundations that enable easy movement of data and vendors.

> Interoperability is the ultimate challenge of a Decentralized Self-Sovereign Identity. Hyperledger Aries is hosting an Interopathon to showcase all the work their community has done to promote Interoperability. We have also started discussions about a standard import/export format that would further improve interop across identity agents.

|
||
> The objective of this workstream was to examine the technology and policy landscapes for digital credentials of INATBA-Governmental Advisory Body (GAB) members, identify the commonalities and gaps, and then develop recommendations for enabling interoperability and mutual support for digital credentials across borders.

> 1. DID methods
|
||
> 2. Content encryption key types
|
||
> 3. Communication protocols
|

> 4. Credential format and signature types
|

> 5. Credential access / storage (wallet)
|
||
> 6. Credential protocols and coordination formats
|
||
> 7. Compatible governance / trust

DHS SVIP has been leading the charge on interoperability for years now, putting their funding and networks on the table to lead the charge.

> Several VC ecosystems have grown up around the VC spec. Each touts standards compliance and interoperability, yet they do not currently interoperate with one another. Let’s have a look at their differences and commonalities, and then explore a simple proposal that might make which language your VCs “speak” as transparent as which language you choose when you watch a movie.

|
||
> While we see the potential to enable interoperability with actors that do not put control in the hands of the subject of the digital identity, we must ensure that this interoperability on a technical level does not undermine the Design Goals that guided the creation of decentralized identifiers in the first place.

> With this badge, they qualify to participate in Plugfest #2 which will focus on issuing and displaying LER VCs. Plugfest #2 will take place in November 2022 with plans to meet in person the day before the [Internet Identity Workshop](https://internetidentityworkshop.com/) on November 14 in Mountainview, CA. If vendors are interested in Plugfest #2 and didn’t participate in Plugfest #1, there is still an opportunity to do so by fulfilling the same requirements listed above including the video and earning a Plugfest #1 badge.

*This presentation on the DHS/SVIP Interop Plug-Fest is epic!*
|
||
> As you know, we had our first Interop plug-fest last year in May 2020, which was a heavy lift for our portfolio companies -- To be blunt, while there was a lot of hand-waving on interop, that was the first time anyone had demonstrated any manner of concrete cross-vendor / cross-platform interop in the VC/DID community.

> ([slides](https://docs.google.com/presentation/d/1MeeP7vDXb9CpSBfjTybYbo8qJfrrbrXCSJa0DklNe2k/edit#slide=id.p1) Through the presentations and demos, we hope that you are able to gain an appreciation of the engineering depth, openness, inclusiveness and the multi-vendor, multi-platform interoperability that we demonstrated that is needed for these type of solutions to internet scale without locking anyone into a particular vendor or technology stack.

> As part of our deliverables for the U.S. Department of Homeland Security's Silicon Valley Innovation Program, we developed capabilities including a MATTR web wallet, CHAPI credential interactions, and direct interoperability with issuance and verification infrastructure built by other vendors. The results of this work are documented in our publicly available open-source test suite: [https://w3c-ccg.github.io/vc-http-api/test-suite/mattr/](https://w3c-ccg.github.io/vc-http-api/test-suite/mattr/)
