Provably Fair

Every Nakamoto Lottery draw uses the Bitcoin block hash as the source of randomness. The block hash is publicly verifiable and impossible to predict in advance. Here’s how the winner is selected:

  1. The target draw block is announced before ticket sales begin.
  2. When the Bitcoin network mines that block, its hash becomes the randomness seed.
  3. The winning ticket index is computed: winner = BigInt("0x" + blockHash) % totalTickets
  4. Entries are ordered by purchase time. Ticket counts are accumulated until the winning index is reached.
  5. Anyone can verify the result using the block hash and the public entry list.

This algorithm ensures no one (including the lottery operator) can influence or predict the outcome.
