How It Works

Three steps to verifiable fairness

1
Seed locked at creation When a raffle is created, a random seed is generated and its fingerprint is published on the raffle page. You can screenshot it or note it down - this is your proof that we locked in the outcome before anyone bought a ticket.
2
Target block committed When entries close, the system locks in the next Bitcoin block height - a block that hasn't been mined yet. No one can predict its hash, including us.
3
Draw executes Once the target block is mined, its hash is combined with the seed and ticket count using SHA512 to determine the winner. The result is mathematical, not manual.
4
Anyone can verify After the draw, we reveal the original seed. You can check it matches the fingerprint that was published before tickets went on sale. If it matches, the result wasn't tampered with. Simple as that.

Why It Matters

Most raffle sites ask you to just trust them

They say the draw is random. They say it's fair. But you have no way to check. You just have to take their word for it.

We do it differently. Before any tickets are sold, we lock in a secret code and publish a fingerprint of it. You can save that fingerprint. After the draw, we reveal the code - and you can check it matches. That code, combined with a future Bitcoin block that nobody can predict, determines the winner. No one - including us - knows the result in advance.

This isn't marketing. It's mathematics.

AI Verification

Verify with AI

Every completed raffle has a verify page with a one-click AI prompt. Copy it, paste it into ChatGPT, Claude, or any AI tool, and it will independently confirm whether the draw was fair. No technical knowledge required.

Technical Details

Under the hood

SHA512 + SHA256 SHA512 for the draw calculation, SHA256 for the upfront commitment. Both industry-standard and impossible to reverse-engineer.
No human input The winner is calculated from the locked seed, a future Bitcoin block hash, and the final ticket count. No party ever knows all three inputs at once. No one picks the winner. The maths does.
Public Commitment published at creation. Seed revealed at draw. All data visible on the verify page.
Tamper-proof Changing the seed would change the commitment hash. Any tampering is immediately detectable.
