🚀 Foundation News

DIF "Frequently Asked Questions" Knowledgebase

DIF has launched a massive knowledgebase, structured as a long series of frequently-asked questions and answers. This synthesizes a year of educational efforts in the interop WG, blog posts, newsletters, and many other DIF inputs in a format we hope will be useful as a reference and onboarding document throughout the decentralized identity space. Please peruse it, particularly the sections about your personal research focus and/or your company's specialty and products, opening issues or PRs on github wherever you feel a correction or addition is needed. This is intended as a community resource, so PRs are open to your input!

Interop WG election

The Interoperability WG is seeking nominations for new chairs. The group is hoping to pivot to a greater focus on testing, so candidates with experience scripting tests or making specs testable (whether in decentralized identity contexts or otherwise) are particularly welcome. For details about the ballot, visit the mailing list or slack channel.

💰 Funding


NGI Open Calls (EU)

  • Funding is allocated to projects using short research cycles targeting the most promising ideas. Each of the selected projects pursues its own objectives, while the NGI RIAs provide the program logic and vision, technical support, coaching and mentoring, to ensure that projects contribute towards a significant advancement of research and innovation in the NGI initiative.
  • The focus is on advanced concepts and technologies that link to relevant use cases, and that can have an impact on the market and society overall. Applications and services that innovate without a research component are not covered by this model.
  • Varying amounts of funding.

Bloom Donates WACI to C&C WG
TLDR; WACI isn’t being donated as a snapshot or as a reference implementation of a finished protocol; it’s being donated as a starting point for an ongoing work item in C&C WG that will round out the spec to be more robust and flexible, after the WACI-PEx profile has been finished and there is feedback to consider from implementers of it, and/or of other applications.

Setting Interoperability Targets - Part 2

[DIF focuses on three distinct] “layers”, each of which has its own interoperability challenges that seem most urgent. It is [the Interop WG's] contention that each of these could be worked on in parallel and independently of the other two to help arrive at a more interoperable community-- and we will be trying to book presentation and discussion guests in the coming months to advance all three.
