Provably Fair, Explained Without the Crypto Jargon

When you enter a sweepstakes, you're trusting the operator. We don't think you should have to.

The problem with "trust us" Traditional sweepstakes pick winners behind closed doors. You're told a name and asked to believe it was random. That's fine — until it isn't.

The provably fair approach Before a draw opens, we generate a secret **server seed** and publish its SHA-256 hash. The hash is a fingerprint: we can't change the seed later without changing the fingerprint.

When the draw closes, we combine the server seed with a client seed (a public value, like the hash of a future Bitcoin block) to compute the winning ticket. Then we reveal the original server seed.

How you verify On the Verify page, plug in the revealed server seed and client seed. The winning ticket number is computed in your browser. If it matches the announced winner, the draw was honest. If our server seed doesn't match the pre-published hash, something is wrong — and the whole community will know.

Math doesn't lie. Neither do we.
