Try a Fair Draw

Step 1 · Seal

Tap a name to edit, ✕ to delete.

Step 2 · DRAND

Rather than fetching a number now, commit to a future round that has not arrived. Only then can nobody know the result in advance.

①Check current round

②Reserve future round (current +2)

③Register to the ledger

Log the seal hash and the future round to use first. (Before fetching the number!)

④Fetch the future-round number

⑤Make the draw seed

Convert the first 16 hex digits of the fetched number to decimal and use it as the draw seed.

No number fetched yet.

Step 3 · Shuffle

Winners: 1

Step 4 · Verify

Leave it and it passes; change it secretly and it is caught. Change anything and press "Verify."
