Provably fair

How each draw is locked down

Two of the proofs are stamped on Bitcoin
  1. 1 · Before sales
    Lock code

    Our secret’s fingerprint is posted before anyone buys and stamped on Bitcoin, so it can’t be faked.

  2. 2 · At lock-up
    Sealed tickets

    When sales close, the ticket list is sealed. Changing any ticket would change its seal code.

  3. 3 · At the draw
    Public random number

    drand publishes a number nobody can know in advance. Each draw uses a round fixed at the seal.

  4. 4 · At the reveal
    Winners anyone can recompute

    We publish the secret. Your browser works out the winners itself.

To check a Bitcoin stamp yourself, download the .ots file and the file it stamps, and drop both on opentimestamps.org.
