The Frankenstein Lottery System

This article was first posted on this site.

Lottery Specifics:

  • Lottery Ticket Fee for 1 ticket: 1 FRANK
  • Single User Lottery Entry Limit: No overall limit, but only 50 can be bought at one time through the UI
  • Paying for one ticket will give users a random 4 digit combination with each digit being between 1–9, for e.g. “1–9–3–2”
  • Lottery will also be funded by adding 0.1% from the amount of tokens minted per block every 24 hours.

How to win:

‌To win the lottery jackpot (50% of the entire lottery pool), users need to match all 4 numbers on their ticket in the exact same order as the 4 winning numbers.‌

If you don’t match all 4, no need to worry. As long as you match 2 or more numbers in the correct order, you are guaranteed to win a prize.‌

Winning Ratio:

  • Match all 4 numbers in the exact order = win 50% of the pot (or split the pot if more than 1 winner).
  • Match 3 numbers in the exact order = win or split 20% of the pot.
  • Match 2 numbers in the exact order = win or split 10% of the pot.
  • Burn the remaining 20% of the pot.‌

Please note — in the event that no participants were able to match 3 numbers on any draw, the 20% allocated to winners will then be burned accordingly.‌

For example, if the final 4 winning numbers are “1–9–3–2”:‌

  • “2–3–9–1” = match 0
  • “1–9–3–2” = match all 4
  • “1–9–2–2” = match 3
  • “2–3–3–2” = match 2
  • “1–2–1–2” = match 2

Lottery Phases:

Each full lottery session is completed every 12 hours (2 per day), with the timings for each as below:

‌3 AM — 2 PM (UTC)‌

3 PM — 2 AM (UTC)‌

3 AM — 2 PM (UTC)

‌3 PM — 2 AM (UTC)

‌An example of a lottery session starting at 3 AM (UTC) is as below:‌

Phase 1 — Buy Tickets (3 AM to 2 PM)

  • You have 1 hour to buy tickets.
  • The lottery jackpot will accumulate at the top of the page with each ticket bought.
  • Users will receive a ticket (comprised of 4 digits) for each 1 FRANK paid.

Phase 2 — Lottery Draw! (2 PM)

  • The 4 winning lottery numbers are drawn and will appear on the page.
  • Each participant’s winnings will be automatically calculated based on their ticket numbers and shown on the page.
  • Users can claim winnings if they have any.
  • Users will also be able to see the lottery results: How many users matched all 4 numbers, 3 numbers and 2 numbers.

Phase 3 — Celebration and Sharing (2 PM — 3PM)

‌If you won, congrats! Share with your friends or in our community groups.

‌The next lottery starts in 1 hour!‌

How are ticket numbers drawn?

‌The lottery aims to be completely random. Even though the ticket numbers given out are determined by a front-end logic, there is an extremely low chance that anyone is able to determine the 4 winning numbers ahead of time.‌

  • The 1st lottery number will be determined based on the %10 remainder of a hash encoded by the blockhash and the number of participating users at the entry deadline.
  • The 2nd lottery number will be determined based on the %10 remainder of a hash encoded by the blockhash and the total pooled FRANK balance at the entry deadline.
  • The 3rd lottery number will be determined based on the %10 remainder of a hash encoded by the blockhash and the timestamp of the last lottery participant at the entry deadline.
  • The 4th lottery number will be determined based on the %10 remainder of a hash encoded by the blockhash and the block difficulty at the entry deadline.
