The order of events

1. Entries close at :00:00
2. The ticket list is locked on chain within 30 seconds
3. About a minute after the hour, a public random number is published
4. That number picks the winning ticket

• The ticket list is locked before the random number exists
• So nobody can choose a winner

drand

• The random number comes from drand, a public randomness beacon
• drand is run by independent organisations worldwide
• The jackpot contract checks each drand value on chain
• Ticket Rush coins are picked the same way

Check it yourself

• The ticket rules are public
• Each draw's ticket list can be rebuilt from public chain data
• Every draw publishes a file with all its inputs
• If a rebuilt list differs from the locked one, the list is wrong
• Where to find them: Stats and verify
