Operating proof · live

Do not take our word for it. The registry is public, and it is countersigned into Bitcoin every day.

Every signed decision across SolvingHealth's brands is fingerprinted (SHA-256, no protected health information) and anchored on the hashcare registry. Once a day the registry root is countersigned into Bitcoin via OpenTimestamps. The numbers below are read live from the registry's published files, not typed by us.

What is running, and what is only designed

The honest inventory. A company page that cannot tell these apart is not worth reading.

Live

Wonder Bill coding check

Paste a de-identified note; the model proposes, the CMS NCCI engine grades, the surgeon signs under her own NPI. Free, no login.

 Live

ClinicalSwipe attestation loop

Specialty-matched, NPI-verified physicians sign, revise, or decline with a documented rationale; each determination is hash-anchored. The first real case was signed in August 2026.

 Live

hashcare registry + daily Bitcoin countersign

Public roots, hash lists, and OpenTimestamps proofs published every day. Anyone verifies; nobody has to trust us.

 Live, sandbox

EHR read/write loop

A FHIR DocumentReference in, an attested receipt written back. Runs against a sandbox with a synthetic note. No production EHR is integrated yet; we do not say otherwise.

 Live, demo

HarnessHealth signature

Draft, held, reviewed, attested, sealed. A demo you can run yourself. No BAA has been executed yet; production terms follow a BAA.

 Early

co-op.care worker-owned care

Care at $35/hr with $26 to the caregiver, Boulder first. Pre-revenue; the first circle is the whole game, and we say so.

Why a company page carries a ledger

Because the accountability layer is the product. A health system, a payer, or an AI company that has to defend a decision later needs a record that outlives the vendor. The registry above is that record, and it is the same one our own brands write to first. If you are deciding whether to trust us, start by verifying one receipt.
