Technology that makes re-draws impossible to hide

Title of inventionDraw management method, system, and computer program that folds the round number of identical-condition draws into the sealed value to make re-runs public
Application number10-2026-0158960

This 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 the moment the draw starts — so no one, Unipicker included, can alter it afterward. The record is published.

The key idea — it doesn't block "redrawing until you like the result." It makes that behavior impossible to hide, because every re-run leaves a public record.

An extension of the fair-draw philosophy — three things form the backbone of Unipicker fair draws: 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 filing adds one more step: recording and publishing the fact that a draw was repeated at all.

SealingThe moment a draw starts, entrant and settings data are locked with a hash, making later changes impossible.
Public randomnessThe draw seed comes from an external public randomness source, so the organizer can't know or choose the result in advance.
Verified drawsThe original draw data and seed reproduce the result exactly, so tampering can be checked.
Round sealing (this filing)Repeated draws under identical conditions are detected, and the round number goes into the sealed value and is published.

Technology that live-streams only the data you verified in rehearsal

Title of inventionMethod, system, and computer program for brokering live-streamed draws by locking data based on a commitment of a rehearsal draw
Application number10-2026-0163851

When a draw live stream is run, the entrant list, draw settings, and presentation settings the organizer verified in a rehearsal draw are recorded as a sealed value (a commitment), and re-checked against that commitment immediately before the broadcast goes out. If anything differs, the broadcast is blocked from starting at all.

The key idea — that "what was verified in rehearsal" and "what actually airs" are the same is guaranteed by machine verification, not by a human witness. And because the commitment is published before the draw randomness is obtained, it's impossible to fix the data and randomness first and fabricate a commitment afterward.
How it works, in four steps
Rehearsal commitmentAn integrity value is created and sealed from the list, settings, and presentation settings used in the rehearsal.
Check and lock at schedulingWhen the broadcast is scheduled, the data is checked against the commitment; on success, that data version is locked as unchangeable.
Publish the commitment before randomnessThe commitment is published before the draw randomness is obtained, making it a genuine advance promise.
Re-check right before airingThe data is checked once more immediately before the broadcast starts; on mismatch, it never goes out.
