Spherity has developed an Ethereum-based credential revocation mechanism for use in the US pharmaceutical supply chain — I have previously written about the importance of managing a registry of trusted issuers in the context of enterprise Self-sovereign Identity (SSI). A credential issuer, in turn, must maintain a registry of revoked verifiable credentials (VCs). What does that mean? Credential management is no mean feat for a responsible issuer…

So, here I was — a non-techie and SSI noob at a week-long expert geek event. What on earth was I going to do during the next 5 days?! What is RWOT? Let’s dial back a bit. RWOT is the acronym for Rebooting the Web of Trust. As part of the bigger RWOT…

Spherity has built an Ethereum-based trusted issuer registry for use in the US pharmaceutical supply chain — SSI Trust Triangle Before we get stuck in, let’s set the scene with a quick recap on Self-sovereign Identity (SSI). There are three key entities in an SSI ecosystem: Issuer, Holder, and Verifier. The relationship of this trio is often referred to as the trust triangle. The credential issuer generates and bestows the…

Personally, I have grown tired of the abundant use of the word trust in blockchain and SSI-related articles, explainers and ads. Not only does it feel heavily overused, the way I have come to understand SSI-related tech is that it’s less about enhanced trust and more about verifiability. …

In November 2013, the US Congress enacted the Drug Supply Chain Security Act (DSCSA) with a 10 year lead time in order to enforce assurance over pharmaceutical drug distribution from manufacturers all the way to dispensers. One critical requirement is the assurance that interactions happen exclusively between Authorized Trading Partners…

Since I plunged myself into the SSI world not too long ago, I’ve been both a learner within a new professional area and increasingly someone trying to explain what I do to others. Unsurprisingly, in both roles the challenge is more fun and rewarding when content is presented creatively with…

I care a lot about adult education because I’m a life-long learner. Having gone through a fair bit of academic, professional as well as continuous informal and unstructured learning, I have begun thinking about the topic from a wider angle. I have previously uttered some thoughts. …

It seems that after an initial frenzy at the start of the COVID-19 pandemic, when seemingly almost any old test could somehow make it on the market (check out the April news review for comments on quality issues), we’ve seen not just quality tests but also kits with added features…

The purpose of a vaccine is effectively to train the immune system in recognising and combatting the virus quickly should there ever be a real infection. To do so, vaccines deliver virus components, which are harmless on their own, to the recipient’s immune system. These components are referred to as…
