Draw Proof Details - Draw #503531611

Prove this draw

The cryptographic inputs published before and after this draw deterministically produce the winning numbers. Click below to run the full verification in your own browser - no server round-trip, no trust required, just the maths.

Step 1. Server seed hash matches the value committed before the draw.
Step 2. combined_seed = SHA256(server_seed + merkle_root).
Step 3. Winning numbers reproduce from combined_seed via Mersenne Twister (Ruby-compatible MT19937).

Cryptographic Proof
This draw uses provably fair technology to ensure complete transparency and fairness. All random number generation is cryptographically verifiable.
Verification Steps:
  1. Server seed committed before any entries
  2. Client seeds collected from all entries
  3. Combined seed used for random generation
  4. Results can be independently verified
Proof Status:

Run the full verification above to confirm the server seed, combined seed and winning numbers all line up. The buttons inside the technical details below also let you re-check each piece individually.

Verification Instructions
  1. Copy the Server Seed (revealed after draw), Draw ID, Nonce, and other commitment data from below.
  2. Verify the Server Seed Commitment by computing:
    SHA256("server_seed:" + draw_id + "|" + server_seed + "|" + nonce + "|" + entropy_sources + "|" + version + "|" + commitment_type)
    Confirm it equals the Server Seed Commitment hash shown below.
  3. Compute combined_seed = SHA256(server_seed + merkle_root).
  4. Generate winning numbers using this exact algorithm:
    seed_integer = combined_seed.to_i(16) # Convert hex to integer rng = Random.new(seed_integer) # Ruby's Mersenne Twister PRNG main_numbers = (1..MAIN_COUNT).to_a.sample(PICK_COUNT, random: rng).sort bonus_number = (1..BONUS_COUNT).to_a.sample(1, random: rng).first Game config for this draw: MAIN_COUNT=40, PICK_COUNT=5, BONUS_COUNT=25
  5. Confirm the recomputed numbers exactly match the published result numbers.
  6. To verify your ticket inclusion in the Merkle root: use the Inclusion Proofs section below, copy the Verifier JSON, and verify with the on-page script or a third-party tool.
This is the pre-image of the commitment. It was kept secret before the draw.
In-Browser Commitment Verifier

Verify the server seed commitment matches the revealed server seed. No data is sent anywhere; verification runs locally in your browser.

External Verification
Note: This system uses custom hashing with prefixes (leaf: and internal:). Standard Merkle tree tools will not work directly. You must implement the specific hashing format shown in the proof data above.
