Technology that makes re-draws impossible to hide
The filed technology detects when a draw is re-run under identical conditions, assigns it a round number, and includes that round number in the sealed value created at the moment the draw starts — so no one, Unipicker included, can alter it afterward. The record is published.
An extension of Unipicker's fair-draw philosophy
Unipicker has built its fair-draw technology on sealing (locking draw data with a hash), public randomness (using randomness like DRAND and NIST that nobody can know in advance), and verified draws (reproducing the result from the original data and seed). This patent filing adds one more step: recording and publishing the fact that a draw was repeated at all.
