Fair winner selection

How to prove a prize draw was fair

A fair prize draw needs a result that can be explained, checked, and defended.

ScirDom packages the core technical evidence into a certificate and evidence pack.

SCIRDOM EVIDENCE LAYER

Tested randomness before the draw
Participant register locked before execution
Published winner-selection algorithm
Signed certificate and evidence pack
Verification material for independent checking

ANSWER

What evidence proves a prize draw was fair?

Useful evidence includes the final participant list, locked execution-order register, when it was locked, the selection method, the randomness source, cryptographic identifiers, a signed certificate, a manifest, and enough replay material to check the result.

ANSWER

Is a screenshot of a random winner picker enough?

A screenshot may be useful operationally, but it is weak evidence on its own. It usually does not show the randomness source, conversion method, locked list, replay path, or tamper-evident record.

ANSWER

What does ScirDom add?

ScirDom records the locked register, entropy reference, algorithm version, result, certificate, manifest, and evidence pack so the draw process can be checked later.

The evidence stack

Participant evidence: who was eligible and what list was locked.
Method evidence: what algorithm was used and whether it removes conversion bias.
Randomness evidence: what entropy block and byte range drove selection.
Integrity evidence: hashes, signatures, manifests, and certificate records.
Replay evidence: enough material for an independent technical check.

What evidence cannot do

Technical evidence cannot fix unlawful terms, misleading advertising, an ineligible participant list, poor prize fulfilment, or inadequate complaint handling. Those remain promoter responsibilities.

Need evidence for a prize draw?

ScirDom helps promoters evidence fair winner selection through tested randomness, locked entries, a published algorithm, signed certificates, and complete evidence packs.
