Every VIABLE credential is anchored to a did:webvh identifier and an X.509 certificate in the eIDAS trust list. The standard flow uses ECDSA + SD-JWT per the eIDAS 2.0 ARF. Switch to Advanced for BBS+ Zero-Knowledge proofs with unlinkable selective disclosure — our deep-tech USP.
Compile your business processes once. Inject them into any VIABLE Wallet via QR or NFC. The wallet itself executes the logic — verifying credentials, transitioning states, triggering actions — entirely offline, with zero metadata leakage to the backend.
A new hire receives an Employee Identity Credential from corporate HR. Days later, they access a third-party benefits portal — proving they're employed without disclosing salary, address, or birth date.
Underground in the tunnel between Alexanderplatz and Friedrichstraße — both the passenger's wallet and the inspector's terminal lose connectivity. The verification still happens: locally cached keys, locally synced revocation registry, NFC tap. Zero backend calls.
