It works where PKI maturity is uneven.
A verified document opens in any browser: no app to install, no account to create, no pre-existing certificate hierarchy required. Zero-installation trust removes a precondition rather than adding one.
WHO GIDH 2026
Sovereign Digital Foundations for Global Health
Open Source trust infrastructure that institutions own, not rent. Proven in Swiss healthcare, open to the world.
Get in touchWho controls the layer that everything else stands on?
You can run a national health stack on open standards, host it on sovereign soil, and write it into law, and still not own it if the trust layer underneath it has a single operator. A foundation with a landlord is not a foundation. It is a lease.
Digital sovereignty is decided at the trust layer, not the application layer.
Why this matters for GIDH
It is ready for what comes next.
Because each organisation controls its own keys, cryptography can be migrated one participant at a time, including the move to post-quantum algorithms, without a global flag day.
It speaks the existing languages.
The architecture bridges to X.509 and complements the federated trust networks already in production. Structured clinical exchange over HL7 FHIR is the next step on the roadmap; it depends on hospital-side onboarding, with the earliest realistic production exchange in late 2026.
This is not a whiteboard
In Switzerland, SEAL delivers more than 800,000 secure, verifiable interactions every month across the national health network operated by HIN (Health Info Net). Verimesh, the full trust infrastructure Suite that extends SEAL, is in early production rollout with HIN now, and the first institutions have been onboarded in June 2026.
Digital health does not fail because of lack of technology, it fails because of lack of trust infrastructure. What Vereign demonstrates in Switzerland is that trust can be operationalised: secure, verifiable and scalable across institutions without compromising control.
