To select winning numbers Gexan lottery uses algorithm based on blockchain:

  • The winning numbers are random and not known in advance.
  • No one can influence the result of the draw, even the developers of Gexan.

How it works:

  • An hour before the end of the draw, the purchase of tickets stops.
  • We take first block of bitcoin blockchain after the time of the end of the draw.
  • Bitcoin block hash is not known in advance.
  • From the hash of the block we get the winning numbers.



Open algorithm code is published on GitHub.

Bitcoin block number is specified for each draw in “Draw archive”.
