A DIF-hosted resource for community development

Introduction

It has been almost three years since DIF began working on the Universal Resolver (GitHub: Universal Resolver) — a foundational piece of infrastructure for the Decentralized Identity ecosystem (see the original announcement). Since then, our vision of being interoperable across ledgers and DID methods has seen a lot of support. Thanks to community contributions, the Universal Resolver now supports around 30 different DID methods.

Today, we are happy to announce an updated set of instances where the Universal Resolver is deployed. …


One of the most important challenges that remain in decentralized identity architecture is the key management. The whole point of a Decentralized Public Key Infrastructure (which is the underlying paradigm that has led to the development of Decentralized Identifiers and many other related technologies) is that individuals, organizations, and things create and manage their own cryptographic keys without reliance on a central authority or intermediary. But as we know, with great power comes great responsibility — in this case, while we have the power to wield private keys that control DIDs, we can also lose everything connected to those DIDs…


Some time last summer, our community around Self-Sovereign Identity (SSI) and DIDs made a fascinating discovery: PIDapalooza, a conference whose tag line is “open identifiers deserve their own festival”.

We were immediately puzzled and intrigued at the same time — how was it possible that there was an entire community dedicated to PIDs (persistent identifiers) that our community around DIDs (decentralized identifiers) has not heard of before? A community that was obviously working on very similar concepts but so far has had zero overlap with ours? So, three of us DID people (Pam Dingle, Kaliya Young, and myself) independently submitted…


We recently published a report on “DID Auth” (PDF, MD), which summarizes ideas and possible architectures that allow you to prove that you control a certain Decentralized Identifier (DID). This report originated at the sixth Rebooting-the-Web-of-Trust workshop and is the result of a collaborative effort by several authors and contributors. There is also a webinar.

But before further discussing DID Auth, let’s first start with a story.

The story of a cute little creature:

One day, a frog asks “Who are you?”, and the little creature realizes that it has a severe identity problem: It doesn’t know what kind of…


On any blockchain or other decentralized system

DIF is introducing a community preview of the Universal Resolver — a core building block of a decentralized identity system. This is a first step in fulfilling DIF’s mission to help individuals and organizations to control their digital identity, without being dependent on any intermediary party.

This tool fulfills a similar purpose as Bind does in the DNS system: resolution of identifiers. However, instead of working with domain names, we work with self-sovereign identifiers that can be created and registered directly by the entities they refer to. This is important, because identifiers are the basis for any identity and communications…
