Once per every 10 days (days ending in 5, such as 5/15/25), a safe and transparent lottery algorithm registered in the blockchain determines the PERIODIC MISSION WINNER. The lottery algorithm receives random number seed from a trusted source outside the block chain (Random.org or Wolfram Alpha) and extracts the two card numbers using a predetermined formula. Two numbers are from the following ranges each.
■ One random card number among all Ether-arts card number issued
Once card is issued, this could be selected as a winner in all future stages. Even if it is selected as a mission winner, that card does not disappear nor its function is not limited. Therefore, the potential value of early-issued Ether-arts cards is very huge.
■ One random card number among N most recently issued ones
One of the N most recently registered art cards is selected. Ether-Arts will add 3-5 new art cards for each stage. However, as the number of registered picture cards increases, the difficulty of the game increases and the winner may not appear for a long period of time. The prize money will grow, but the boredom of the participants also will grow. Therefore, the Ether-Arts team will have the authority to change the N value for proper difficulty adjustment.
One of the main benefits of a recent winner card policy is to motivate new players to buy. Players who have recently purchased 2 cards are more likely to win a first prize even if they do not have an old card. Players with old ether-arts cards can always resell cards at a higher price because there is always a demand for older cards in this market.
