Spend what your dragons earned

Raffles

Tickets cost embers. Every entry is sealed on Hedera before the draw, and the winning number comes from Hedera's own randomness, not from us.

How a draw is decided

  1. 1

    The terms are sealed

    Before the first ticket is sold, the prize, the price, the closing time and the number of winners are written to a Hedera topic. They cannot move after that.

  2. 2

    Every entry is written down

    Each purchase goes to the same topic with the running ticket total, timestamped by Hedera. Nobody can be added to a raffle after it closes, us included.

  3. 3

    Hedera rolls the number

    The winning number is generated by Hedera's consensus nodes in a transaction of its own. We do not pick it and we cannot see it coming.

PRNG: the number nobody chose

Hedera has randomness built into the network. Asking for it is a transaction like any other: the consensus nodes produce a number from the running hash of the ledger, put it in the transaction record, and that record is public forever. Nobody can predict it beforehand, and nobody can change it afterwards, us included.

Tickets weight the odds. Ten tickets occupy ten of the numbers the roll can land on:

Holding requirements are re-checked at the moment of the draw: a wallet that qualified when it bought and has sold since is skipped, because the raffle said you had to hold one and at the moment that mattered you did not. If Hedera's randomness is unavailable the draw does not run at all rather than falling back to a number we picked.
