Each of the selected projects pursues their 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 amount of funding

KERI: For every DID, a microledger
by DIF on DIF Medium

“The Digital Identity Foundation (DIF) is very proud to be hosting one particular research and development project that could prove pivotal in this process. It is currently a work item of DIF’s Identifiers and Discovery Working Group. However, a charter for an autonomous working group will be available for review at #IIW31 this week (20–22 October 2020) to facilitate broader participation. The project is called KERI and it is a project that could only be developed in the open, for the public good and for the widest, quickest adoption.”

Drilling down: Open Standards
by DIF on DIF Medium

“In the software world, as in the world of trains, standards define a given market for products and services. Compliance tests make objective (and far less controversial) the question of whether or not a given product meets a given set of requirements. Explicitly-defined, testable protocols make products provably swappable and/or interoperable. Open standards processes try to define those tests and protocols in the open, with input from initial and future contenders in that market, speeding up the timeline to legitimacy by incorporating major players and incorporating widely-sourced input.”

Understanding DIDComm
by Kaliya Young on DIF Medium

“DIDComm is a cross-community standard that creates libraries and design patterns for two or more DID-controlling entities from diverse DID-based systems to communicate directly with one another. It creates a secure communication channel between software controlled by each of these entities, which can be people, organizations or things. This constitutes an “authenticated channel,” in that control of a given DID’s private keys is, barring a failure of design or operational security, proof of authenticity of the party represented by that DID.”

DIF at #IIW31
by Kaliya Young on DIF Medium

“DIF has had great success presenting work at IIW — and increasingly, it is becoming an important aspect of our educational and outreach efforts to post recordings of these presentations on our youtube channel. We’re hoping this tradition will build more momentum at the upcoming IIW!”


#IIW Internet Identity Workshop
October 20-22, 2020 - Online

The Internet Identity Workshop (IIW) has been finding, probing, and solving identity issues several times per year since 2005. Every IIW moves topics, code, and projects downfield. Name an identity topic - it’s likely that more substantial discussion and work has been done at IIW than any other conference.
