Cryptographic Proof

This draw uses provably fair technology to ensure complete transparency and fairness. All random number generation is cryptographically verifiable.

Verification Steps:

Server seed committed before any entries
Client seeds collected from all entries
Combined seed used for random generation
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

Copy the Server Seed (revealed after draw), Draw ID, Nonce, and other commitment data from below.
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.
Compute combined_seed = SHA256(server_seed + merkle_root).
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=30, PICK_COUNT=4, BONUS_COUNT=9
Confirm the recomputed numbers exactly match the published result numbers.
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.

Server Seed (revealed after draw)

This is the pre-image of the commitment. It was kept secret before the draw.

Server Seed Commitment (SHA256)

Commitment Nonce

Draw ID

Version

Commitment Type

Entropy Sources (sorted keys)

Merkle Root (Committed Entries)

Combined Seed (SHA256 of server_seed + merkle_root)

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.
