How to draw winners and airdrop reward?
(1) Take the hash value of last ETH block before 4:00 (UTC) on the draw day (including 4:00) as the winning sequence of that day.
(2) Filter the letters from the end of the hash value, and take the last 20 digits to get the winning sequence of that day.
(3) During the event, the user’s net buying volume of RING or KTON will be converted into USDT for ranking.
(4) Match the transaction ranking with the winning sequence. Take a single non-zero number in the first three digits as the winning number (if the selected number is 0, then skip to the next one digit), and the subsequent seven two-digit numbers are taken as the winning number. Participants who matched the ranking will be winners and get relevant reward through airdrop.
(5) For example:
a. Assume that the hash value of the last specified block before 4:00:00, September 7, 2020 (UTC)
is:0x95519f40a75c3f46d0426d5db908458b3d056b929d02b536c1c6d431ec94f093
b. Filter the letters from the end of the value to get a string of numbers:
09551940753f46042659084583056929025361643194093
c. Keep the last 20 digits to get the winning sequence of the day: 56929025361643194093
The winning numbers are: 5, 6, 9, 29, 02, 53, 61, 64, 31, 94, then user whose ranking is 5, 6, 9, 29, 02, 53, 61, 64, 31, 94 will be selected as winners and get RING worth 50 USDT and KTON worth 50USDT per person through airdrop.
