Provably fair — cryptographic Draw complete

Draw complete — independently verifiable

This draw used a cryptographic commitment scheme. The draw secret was generated before ticket sales began, its sha256 hash (the commitment hash) was published, and the secret was only revealed after the draw. This proves the winner selection could not have been influenced by ticket sales.

SHA-256 commit-reveal — selection by sha256(draw_secret:pool_hash:counter) with rejection sampling

How This Result Was Produced

4 steps, each one checkable against the values published below. Nothing here depends on trusting us — every input is shown.

Verify commitment was published before the draw

This sha256 hash was published when the competition was created. It proves the draw_secret could not have been changed after tickets were sold.

Verify draw_secret matches commitment_hash

The draw_secret is revealed below. sha256(draw_secret) is shown — it must equal the commitment_hash in step 1.

Verify the entry pool hash

sha256 of every ticket number in the draw pool, in ascending numeric order, joined with commas and no spaces. Instant-win tickets in this competition were settled at purchase and are not part of the main draw pool.

Reproduce the winner selection (rejection sampling)

Starting at counter=0, compute sha256(draw_secret:pool_hash:counter) as a 256-bit integer. Let limit be the largest multiple of N below 2^256. If the value is >= limit, increment counter and retry. Otherwise winner_index = value mod N.

counter=0, winner_index=4

Check It Yourself

Run every check in your own browser. It recomputes the hashes and the winner selection locally from the values published on this page — nothing is sent to our servers, so a pass cannot depend on trusting us.

  1. Confirm sha256(draw_secret) equals the commitment hash in step 1.
  2. Confirm the sha256 of the entry pool below equals the pool hash in step 3. Hash the text exactly as shown — ticket numbers in ascending numeric order, separated by commas, with no spaces and no trailing newline.

Independent Timestamp Proof

Each commitment hash is anchored to the Bitcoin blockchain via OpenTimestamps. A confirmed proof establishes the hash existed before the Bitcoin block that attests it — checkable without trusting our records. Save the commitment hash to a file and check the proof with the free ots tool: printf '%s' 'COMMITMENT_HASH' > commitment.txt && ots verify -f commitment.txt proof.ots
