> 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. Lets 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.
* [DHS/SVIP Interoperability Plug-Fest 2 : Features Under Test ...](https://lists.w3.org/Archives/Public/public-credentials/2021Mar/0022.html) John, Anil
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.
This presentation on the DHS/SVIP Interop Plug-Fest is epic!

> ([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.

> [Interoperability](https://medium.com/transmute-techtalk/the-business-case-for-interoperability-a1a2b884297d) 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.

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

> 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/)

Were very pleased to announce that our proposal “Presentation Exchange Credential Query Infra” has been selected as 1 of 7 out of 299 proposals to join the second Infrastructure-oriented program of the EUs eSSIF-Lab.
Well be providing a Presentation Exchange that creates interoperability between W3C DIF-compliant Verifiable Credentials and Hyperledger Aries-based Verifiable Credentials for the European Blockchain Services Infrastructure (EBSI).

Accurate labeling, interoperability profiles, and testing are urgently needed to drive interoperability and scale decentralized identity, says a new [white paper](https://indicio.tech/wp-content/uploads/2022/03/Indicio_Report_TrustVerifiableCredentialsInteroperability_033022.pdf) from Indicio
Seven aspects of interoperability
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

Many implementers wont realize the potential of SSI until its deployed at scale, but in order to get to scale, we need implementers to realize value. Its the classic chicken & egg problem.

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 lines of action of the laboratory are framed in six blocks: resilient water resources, the impact of global change; efficient infrastructure management; the environment and health; water and energy; and water demand management. The projects developed contribute to the achievement of one or more Sustainable Development Goals, putting the citizen at the center of digital transformation and advocating a perspective on technological humanism.
They are actually coming to the [Interoperability Working Group](https://www.notion.so/Interoperability-WG-a42995c37e2a4511a10aea96cdbccc38) this coming week to share results. Here is what they had to say about SSI:
A Self- Sovereign Identity can unlock the full potential of the digital global economy. The identity of people, organizations and things is relevant to any transaction, while protecting Personal Identifiable Information (PII) is of increasing importance.

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 didnt 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.
