Unipicker random — the final fallback
Used only when both DRAND and NIST fail to respond — this is the final fallback. Even so, the whole seed-generation process is published so it can never be manipulated.
Concept
The last card of the three
Unipicker random is used only in the rare case where both the 1st-choice DRAND and 2nd-choice NIST backup randomness fail to respond. It's a final safeguard that keeps a draw from stopping even when no external public randomness source is available.
Procedure
How Unipicker generates this seed
Unipicker generates and manages this "seed" fairly through the steps below.
- The entrant's "seed request PC time" and the "seed request receipt server time" are each converted to Unix time and summed.This policy keeps neither Unipicker nor the organizer from unilaterally deciding this seed, which determines who wins.
- The sum is hashed with SHA(sum), then the first 16 hex digits of the hash are extracted and converted to decimal to use as the seed.
- Unipicker publishes its "seed-issuing server" live.
- Any Unipicker member can monitor the seed-issuance status in real time.
- You can check the entrant's current PC time and the seed server's server time directly.
- A seed-issuance demo lets you check that a seed is issued correctly at that moment.You can check this in Unipicker Software > Fair Draw > Seed Server Lookup.
Summary — Unipicker random is the final fallback, used only when both DRAND and NIST fail. Its generation process and issuance status are published live and transparently, keeping it fair even as a final fallback.
