Every ticket carries a receipt you can recompute
SHA-256When a ticket is issued we hash its contents — your lines, its position in the draw, and the hash of the ticket sold before it — into one value printed on your receipt. Hand back those four things and you can recompute that hash yourself, on your own machine, and see that your ticket has not been altered or reordered since you bought it. It is derived from your data, not a random string dressed up to look like a hash.
