Simple Lottery Ethereum

  1. The user will initiate the contract.
  2. The System will Set lottery duration and save to world state the total duration.
  3. The user will load contract address.
  4. The user will buy ticket.
  5. When user successfully bought a ticket, System add users addresss to ticket list in world state.
  6. When duration will lapsed,
  7. User will draw the winner if he/she will be the winner.
  8. When user draw the winner, the system will generate random unsigned integer.
  9. After that, system will Use the generated integer to select an adress to Ticket list in world state.
  10. After that, system will Assign winner's address that will retrieved in world state.
  11. When the address verified successfully, the user will withdraw the prize.
  12. When withdrawing the prize the system will transfer balance to winner's address. END

Recurring Lottery Ethereum

  1. The user will initiate the contract
  2. System will provide new round
  3. The System will Set lottery duration and save to world state the total duration
  4. The user will load contract address
  5. The user will buy ticket
  6. The System will end the time or duration lapsed
  7. User will draw the winner
  8. When user draw the winner, the system will generate random unsigned integer
  9. After that, system will Use the generated integer to select an adress to Ticket list in world state
  10. After that, system will Assign winner's address that will retrieved in world state
  11. When the address verified successfully, the user will withdraw the prize.
  12. When withdrawing the prize the system will transfer balance to winner's address
  13. Add 1 to round counts
  14. The system will initiate new rounds
  15. If the round counts is less than or equal to 100, the system will be deleted 1 round

RNG Lottery Ethereum

  1. Every buyer submits a commitment hash when they buy a ticket.
  2. Users is generating their number which they want to submit.
  3. Users secret number and address will be added to ticket list.
  4. Ticketing period is over. Tickets cannot be purchased after this period.
  5. Users must reveal their own secret number. All reveals must occur after the ticket deadline and before the reveal deadline.

  7. If failed to submit their own number and address, dropped from the lottery.
  8. Draw winner and Withdraw are nearly identical to SimpleLottery.
  9. Draw winner
  10. Generate random number, it will enable to select the users address to ticketlist.
  11. Generate random seed for picking a winner, this is random seed to determine the winner. Each time a secret number is revealed, the seed is modified to incorporate the reveal.
  12. Withdraw
  13. Balance will be added to users address and will added to world state to verify the address of the user.
