Fair draws · LESSON 2
Unipicker's 6 principles — how we keep them
See at a glance what technology Unipicker uses to keep the 6 fairness principles you just learned.
Summary
6 principles × Unipicker tech
| Fairness principle | Unipicker does this |
|---|---|
| Even | Rejection sampling · order shuffle (Fisher–Yates) |
| Commit ahead | Seal draw materials (hash) |
| Unpredictable | DRAND, NIST, CSPRNG |
| Unchangeable | Change after sealing and the hash differs, caught |
| Verifiable | Recompute the result to verify |
| All recorded | Kept entirely by the draw-ledger system |
The algorithms, hashing, and DRAND you have learned all come together here.
Public draw
A live public draw anyone can run
Running a public draw — one whose entire process is shown live — lets anyone watch that nothing was manipulated. Unipicker's algorithms and public randomness (DRAND · NIST) are designed to be verifiable from public information alone, with no special equipment or access needed, so an on-site public draw or live stream can prove fairness just as well as any other method.
