Interop

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!

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).

These will probably always differ and make a universal abstraction impossible; and thats not a bad thing! These requirements are always going to be specific to each regulatory context, and without them, innovation (and large-scale investment) are endangered by regulatory uncertainty.

The Interoperability working group will be tracking them and providing guidance and documentation where possible. Importantly, though, there is a new DIF Working Group coming soon, the Wallet Security WG, which will dive deeper into these profiles and requirements, benefiting from a narrow scope and IPR protection, allowing them to speak more bluntly about the above-mentioned details.

Having shown in our last piece how interoperability “profiles” are designed, we now tackle some key technical problem areas ripe for this kind of profile-first interoperability work across stacks.

After a public review period during June with stakeholders in air travel, government, healthcare, hospitality, and other affected sectors, the Blueprint was finalized in mid-July for final approval and publication. “Publication of the V1.0.0 Blueprint is just the first step in seeing interoperable privacy preserving digital health passes adopted in order to support people being able to gather together again with lower personal and public health risk,” said Kaliya Young, chair of the Working Group and Ecosystems Director at CCI. “Our next task is collaborating with real world implementers to fill in any remaining gaps to get to an interoperable system and working with LFPH and other partners to deliver open source code that can be deployed.”

In collaboration with the BC Mines Trust Ecosystem, we demonstrate interoperability between organizations using the BC Gov Business Partner Agent and the NB Orbit Mobile Wallet for managing sustainable mining practices.

The "Transatlantic SSI Interop" experiment was successfully conducted to demonstrate interoperability between the EU EBSI Diploma use case, and the US SVIP Permanent Resident Card use case. This was jointly planned and executed by EU partner Danube Tech and US partner Digital Bazaar.

Accurate labeling, interoperability profiles, and testing are urgently needed to drive interoperability and scale decentralized identity, says a new white paper 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.

The Cardea Community at Linux Foundation Public Health is pleased to announce the third Interop-a-thon on June 16, between 8:00am and 12:00pm MST (UTC-7:00). Anyone building a Hyperledger Aries compatible product or system can sign up here.

It does this through selective disclosure, whereby the recipient requests the minimum of information in conformance with GDPR. Identiproof is one of the first systems built to the 2019 W3C recommendations: The Verifiable Credentials Data Model and Web Authentication (FIDO2) - two new global web security standards.

EU-Interop

The European Commission and the European Blockchain Partnership are laying the foundations to implement it in the different EU member states, both in the public and private sectors, launching the European Blockchain Services Infrastructure (EBSI) network, with the aim of 'leveraging blockchain to accelerate the creation of cross-border services for public administrations and their ecosystems

At TBD, we support open standards wherever appropriate, and all of our projects are open source.

Spruce and TBD are the first two organizations to demonstrate support for all five JWS algorithms for JsonWebSignature2020 (Data Integrity Proofs) and JWTs, for VCs and W3C Verifiable Presentations, which is a major step toward vendor interoperability.

The "Data Governance and Semantics" project featured three webinars introducing DDE as a decentralised trust infrastructure acutely aligned with the current movement toward data exchange models in the Economic domain where actors regain transactional sovereignty to share accurate information bilaterally.

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.

This represents the last phase of the AS4EDI20 project to implement the CEF eDelivery AS4 profile in Europe. This project is co-financed by the European Commission through the CEF Telecom program and managed by HaDEA, with action number 2020-EU-IA-0024.

We are keen to support more interoperability activity and hopefully testing this fall and winter. In order to do this we would like to gather feedback from the community as to where we are at so we can assess how to move forward.

Please Note: Information on this survey will be shared with the chairs of the DIF Interop Group

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.
