Both, the insurer installs this to produced portable evidence that end users can consume. Would mainly be the startups building AI agents that interact with insurers on behalf of hospitals. If a hospital needs to process 100,000 claims made by agents and verify them, its their records pitted with vendor logs. This lets the vendor hand over a folder the hospital verifies independently with openssl. No vendor trust required. The incentive: customers (clinics) can process deterministic evidence independent of the vendor or tool (my code) and the vendors agents build up a track record of trust by themselves without engineers spending their time triaging.
