Verify your identity once
A quick biometric check proves you're a real, unique person. No bots, no duplicates — the integrity research demands.
How it works
From your answer to your reward — in four steps
GHDC keeps the data off-chain and the economy on-chain. You're in control the whole way.
Tell us how you use your meds
Say which meds or supplements you take, in the standardized WHO protocol, with global medicine search — simple, and exactly what science needs.
Your info goes anonymous
Whatever identifies you never leaves the secure vault. Only anonymized, aggregated data — protected by k-anonymity — reaches research.
Earn from the economy
Every verified answer becomes a reward in a transparent, trust-weighted on-chain economy. Your experience, your value.
A two-sided protocol
One dataset. Value for both sides.
People who contribute get rewarded for what they share. People who research get evidence they can actually trust.
Your experience with meds finally pays off
- Stay the owner of what you share — without giving it away
- Earn a reward for every verified answer
- Help show what really works with meds, in real life
- Take part from anywhere in the world
Decision-grade real-world evidence
- Standardized WHO-protocol data, globally comparable
- Privacy-preserving by default (k-anonymity)
- Verified, de-duplicated humans — not bots or panels
- Signals for effectiveness, safety & label expansion
The economy
A hybrid token that rewards real participation
Off-chain data, on-chain economy. Buy-back, utility and governance in one — rolled out gradually and responsibly as the protocol matures.
Earn
Every verified answer earns from each epoch's pool — weighted by a quadratic trust score, so quality wins, not volume.
Sustain
Demand for real-world evidence funds buy-backs that send value back to contributors. A real economy, not an airdrop.
Govern
The token carries utility and a voice — the community helps steer the protocol as the network grows.
Privacy & trust
Privacy-first — not privacy-eventually
Trust is the product. Every design decision protects the people behind the information.
Two isolated vaults
Whatever identifies you stays in a network-isolated vault. The research vault holds only anonymized data — they never mix.
k-anonymity at export
No record is released until it blends into a crowd. The 18 HIPAA identifiers never reach the analytics layer.
Biometric integrity
Mandatory biometric verification guarantees one real person per account — the integrity research can rely on.
You stay in control
Contribute, see your impact, and stay the owner of everything. Consent is explicit and you can revoke it anytime.
