Nader HelmyLast month’s Internet Identity Workshop (IIW) was held entirely online for the second time in its history. This bi-annual unconference, typically hosted in Mountain View, CA at the Computer History Museum, connects a wide variety of people from across the globe focused on solving the hard problems around digital identity. As an unconference, the attendees set the agenda each day. The format is focused on open collaboration which creates a real and rare opportunity to organically discuss not only the latest technology developments, but also the surrounding social, political and legal implications.

Nader HelmyThe MATTR team is excited to announce a critical new addition to our product capabilities. We’re continuing to build out an extensive suite of features to support the exchange of Verifiable Credentials (VCs), leveraging the best efforts of the open-source community along with a number of distinct product innovations. These innovations include our recent work related to using BBS+ signatures for privacy-preserving selective disclosure and our earlier work on the OIDC Credential Provider spec. We’ve also been busy sharing new tools for checking the syntax of a JSON-LD credential during development. Read More↗

Emily Fry and Tobias LookerJSON-LD, based on the ubiquitous JSON technology, is rapidly gaining adoption on the web. JSON-LD is an innovation relevant to both business minds and developers alike. For those unfamiliar with this technology, this short video is a great introduction. At MATTR we use JSON-LD in a variety of ways. For example, the platform generates credentials using this technology so that they can be inherently understood and referenced. Read More↗

Karyl FowlerTransmute believes that cross-vendor interoperability is critical for commercialization of decentralized identifier (DID) and verifiable credential (VC) technology. To interoperate means that a computer system or software has the ability to exchange and make use of data from a different system or software "via a common set of exchange formats." Read More↗

Nader HelmyVerifiable Credentials, a standard at the W3C as of late last year, is a verifiable data model which can be represented in multiple different assertion formats. Essentially, these formats, or ‘types’ of verifiable credentials, are just alternative ways to represent the same information. Read More↗
7 minute read | MATTR |8 May 2020A solution for privacy-preserving Verifiable Credentials
Nader HelmyThe recent ratification of Verifiable Credentials (VCs) as a new standard at the W3C defines a powerful new data model for interoperability of identity technologies. As a standard it also represents a disruptive shift in the future design options of digital systems, towards ones that feature more portable and user-centric digital identity, often referred to as ‘self-sovereign’ or ‘decentralized identity’.
