Joint wins at the Diffusion 2019 Berlin Hackathon in the “Identity and beyond” track, demonstrating the power of SSI verifiable credentials.

It’s been a really busy time for the Joint team as of late, as things picked up speed tremendously. As we move forward, the world seems more and more aligned with the notion of communicating our needs through a user-held identity and contextual approach to information. Leveraging on these trends, we’ve recently had the pleasure to partake in the Diffusion Hackathon in Berlin, organised by Outlier Ventures VC, a forward thinking crew, aiming to consolidate a number of technology stacks necessary to successfully deploy the concept of Web 3.0, of a fairer, less monopolised internet.

We are happy to inform that Joint won the the “Best integration of Self-Sovereign Identity credentials” in the “Identity and beyond” track of the Diffusion competition. Ease of use is the holy grail for new technology adoption, so we are especially stoked by this particular award. Our aim was to integrate Sovrin SSI credentials within the contextualised, mind-mapped Joint data structure, enabling for meaningful, provable interactions with the outside world. We would like to thank the folks at Evernym and Outlier Ventures for their ongoing support in our quest — it would be hard to achieve this without their caring oversight. All in all, we are humbled and proud by this development, as the collective IQ, the vision and the community gathered around the Outlier Ventures’ Convergence Stack is very high, and gaining momentum by the day.

Joint Self-Sovereign Identity integration challenge

Joint breaks away from this crippled, flattened version of “us”, and lets the users managed their life in contexts, tied to specific activities and interests. A single “Joe” can be split into a “Joe the Java coder”, “Joe the football fan”, “Joe, the rock climber” and so on. Different verifiable SSI credentials are attached to Joe’s sub-identities, and are revealed to interested parties, without breaches of privacy through exposure of irrelevant information. On top of that, Joint uses intent casting to build marketplaces, which in conjunction with sub-identites, allow for high degree of privacy and building of transactional trust. Users can easily prove their claims, but reveal only the necessary information for a given interaction to take place. Contextual task management is also part of the Joint ecosystem, sealing the loop into a fully functional life management system, in which we own and manage our world through our needs and relationships, and not through separate applications competing for our attention.
