VITALSverifiable clinical replayRUST · SOLANA · AGPL-3.0
Free for every learner, in every country, forever

A patient is dying on a clock.
You decide what happens next.

Anyone can play. Nobody can fake the replay. Talk to her, treat her — a deterministic physiology engine decides if she lives. Every run reduces to one hash anchored on Solana, so anyone can replay the tape and get the same answer, without asking us.

▶ Play — no signup, ~60 seconds to your first patient Source (AGPL)

One run, four facts

Talk to her

She answers in her own words. She can be wrong, and she can be too breathless to answer.

Treat her

Orders, drugs, airway, fluids — a live bedside monitor moves the way the physiology moves.

She lives or she doesn't

No script. A deterministic clinical automaton decides in real time, from what you did and when.

The run is provable

Every case reduces to one hash. Replay the tape, get the same answer — no trust required.

Not a prototype

Our mission: 1% more doctors who actually reach patients, every year. 9.1% of medical students never finish, and the largest single cause is academic difficulty. We find the learner who is going to fail before they fail, and route them to the practice that closes their specific gap.

Why a chain is load-bearing here

The program refuses its own user

Progression is recomputed on-chain from Merkle proofs. Claim a level you didn't earn and the program rejects it — no issuer key, no oracle.

Proof that crosses borders

A residency programme in another country can verify a record without trusting us or the school that produced it.

Donations the donor can audit

Money given for a scenario can only fund that scenario — enforced by the program, released against the delivered content hash.

Stated before anyone asks: 40 of 100 rubric points are re-derivable; 60 are attested by named judges. We cannot prove who sat at the keyboard — identity binding belongs to the credential issuer. And we do not grant standing: only a medical board can make competence authoritative.
