For researchers

Cohorts of consented patients. Queries that respect them.

Sealed-enclave access to longitudinal health records — with the patients who contributed paid, on chain, every time you query. Phase 1 — mechanism live, accepting first-cohort applications. If you are a credentialed researcher with an IRB approval and a defined question, we will work with you on the first contract.

What "Phase 1" means for you

The mint mechanism, the sealed enclave, the consent enforcement, and the chain ledger are all implemented and tested. What has not happened yet: a real researcher contract has not yet been signed. The first contract gets full attention — bespoke onboarding, direct lines to the engineering and ethics teams, your IRB submission reviewed alongside the first attestation cycle. We will not list your institution as a partner publicly until you ask us to. The only listing that will go up before your sign-off is the chain record itself, in pseudonymous form, when the contract executes.

Real longitudinal records

Patient-level data spanning encounters, labs, meds, vitals, axis trajectories, and outcome events. Datavault enrolls patients with continuous longitudinal histories; the median patient depth and quartile-1 depth will be published on this page as a live data-fact once the first cohort is queried, not as a marketing claim.

Opt-in consent

Every patient in every cohort opted in by consent class at signup and can revoke at any time. You don't deal with broker provenance; the chain proves it.

Audit-ready outputs

Every query, contract, and mint event is on chain. IRB submissions and reproducibility packages reference chain hashes; reviewers can verify cohort definitions independently.

Sealed enclave

Notebooks run inside a Datavault enclave with no outbound network. You see aggregates and figures; you do not download records. SOC 2 Type II is on the Phase 2 attestation timeline — see attestations for the schedule.

Indicative pricing

HCR per-cohort, transparent rate card, no negotiation per query. Volume tier for institutions with active programs. Settlement same-chain. Card below is indicative; final Phase 2 rate card will be ratified by the Trust Council before the first contract.

Patients are paid

HCC mints to contributing wallets every time you run a query. Your IRB submission can describe this directly — and patients can see it in their Orb.

Indicative rate card.

Indicative — Phase 1. The Phase 2 Trust Council will ratify the final rate card before the first contract; revisions thereafter are governance events with 30-day public notice.

Cohort size	Query class	Indicative base	Notes
n < 200	any	blocked	k-anonymity floor — non-negotiable
200 – 2,000	aggregate only	1,200 HCR (indicative)	differential privacy applied
2,001 – 20,000	standard	3,400 HCR (indicative)	most common tier
20,001 – 100,000	standard	9,800 HCR (indicative)	requires program agreement
100,001+	standard	quoted	Trust Council review
any	longitudinal re-pull within 12 months	+30%	over base

All prices subject to ratification before Phase 2 launch. The cohort floor (n < 200) is non-modifiable downward and is enforced by the enclave at query time, not by policy.

What we ask in your application.

Institution and credentials. Your home institution, your role, and your current researcher credentials (NIH eRA Commons, ORCID, or equivalent).
Ethics-board approval. An IRB approval ID (or non-US equivalent). The ID will be pinned on chain alongside your contract and verified by the IRB Approval Verification attestation in Phase 2.
The question. One paragraph. What outcome variable, what cohort criteria, what timeframe, what hypothesis. We are looking for well-formed clinical questions, not fishing trips.
Output expectations. Whether you expect aggregated tables, regression coefficients, survival curves, or a notebook-style figure. The enclave will scope what computations are allowed before the contract is countersigned.

We will respond within 3 business days with a sample cohort scope and indicative pricing. If the scope is feasible and you want to move forward, we will draft the contract and pin it to chain together.

Apply for cohort access.

Send your institution, IRB info, and a one-paragraph description of the question. We will respond with a sample cohort scope and indicative pricing within 3 business days. As Phase 1 — first researcher contract — we will work directly with you on every step.
