Explaining VDR, DIDs and VCs The verifiable data registry and introduction to the IOTA DLTįor an SSI ecosystem involving different actors communicating with one another, it is crucial to have a common public storage location to retrieve important information about identities. While the trust triangle, wallets, and governance framework are already covered in other articles, this article focuses on the technical explanation and application of the VDR, DIDs, and VCs. These blocks include verifiable data registries (VDR), the trust triangle (issuer, holder, and verifier), digital wallets and agents, decentralised identifiers (DIDs), verifiable credentials (VCs), and the governance framework. Achieving this crucial step towards privacy requires accurate application of the basic building blocks of SSI. They (the subject) can then control how their data is shared and used. We will also discuss how to get started with the technology using the IOTA Identity Protocol (a framework built by the IOTA Foundation).Īs described in the introduction to SSI, SSI is about shifting control of data from a central organisation and verifier to the identity subject (i.e., an entity, a person, organisation, or object for whom the identity is created). In this article, we will explain the technical details of how SSI and its elements work. Silvano WF, Marcelino R Iota tangle: a cryptocurrency to communicate internet of things data.After reading the first few articles from the Tangle Labs Blog, you should now have a good idea of what SSI (self-sovereign identity) is, how it can help to solve the problems of the “Web2” world, and some of the use cases where SSI can provide novel solutions.
