Decentralized Key Management / Self Sovereign Identity holds the promise of a truly decentralized, self-verifying PKI. Approaches like KERI, the Key Event Receipt Infrastructure, balance privacy, verifiability, and the protection from duplicity. But their promises have remained largely academic thus far. In 2026, the Swiss Healthcare System will be the first large-scale deployment of this kind of infrastructure, using it to upgrade the trust, security and privacy levels of its aging email infrastructure. The result will be a production ready technology stack that can be utilised for a large number of use cases around communication.

Georg Greve is centrally involved in that transition, and will share the road travelled so far, the current state, and the next steps for this transformation.
