How the winners were picked
- Sealed entries: SHA-256 of every stick, locked before the draw
73e3b4f5bf…6f3be3- Beacon value: public randomness nobody knows in advance
a3f1c9e07b…9d0f2a- Seed = SHA-256(sealed entries | beacon | version)
f79662e5e7…7efb0b
Each stick is ranked by SHA-256(seed | stick). The lowest ranks win.
This demo uses a made-up beacon value. A real draw uses the drand beacon for the draw time.

Listed in the order they submitted. Ties go to whoever submitted first.
Rewards are calculated after the creator settles this quiz.
Grabbing a red packet
Section titled “Grabbing a red packet”- Open the red packet card and tap Open (enter the claim code first if there is one).
- The money lands straight in your Mixin wallet.
- One grab per person; whether it’s a lucky-draw or an even split is up to whoever sent it.
Common limits: new members only (people who joined for the first time in the last 24 hours), a Spark level, or Rewards invitees (invited into the circle and verified via Mixin Rewards). If you don’t qualify, the page says why. When a red packet expires, whatever is left goes back to the sender.
Verifiable lottery
Section titled “Verifiable lottery”- Tap Shake for your stick and you get a number (your stick number).
- When the draw time comes: after every stick number is sealed, the winning entries are worked out using the public drand randomness beacon (published by the League of Entropy).
- The results page carries the full proof: the beacon value, the algorithm, every stick number and every winner — you can replay the whole verification in your browser with one click. You don’t have to trust anyone.
- Entries close 1 minute before the draw; winnings move to your Mixin wallet automatically.
Submit your answers within the time limit; your score is how many you got right. The rules are spelled out before the quiz starts: what share of the prize pool goes to perfect scores and what share to the top N, with ties broken by who submitted first. The organizer settles the quiz after it ends, and rewards go out automatically then.
Twitter Follow task
Section titled “Twitter Follow task”Follow the target account on X as prompted, then come back and sign up. Note that the platform doesn’t check whether you actually followed — signing up is just a record. If the organizer confirms success, the prize pool is split evenly among everyone who signed up; if not, it’s refunded to them.
Your entries
Section titled “Your entries”The Mine page in Oh My Luck lists the activities you’ve joined and how they turned out (waiting to draw, won, settling, and so on).
