Lucky Draw Rules Bases on Binance chain Hash value
Binance
2021-02-01 11:43
  • We will take the final 8 numeric digits of the last Binance chain hash value at 11:59 PM (UTC) on the specified day of this promotion period as the winning number.
  • We will then use this winning number to match User IDs from the first digit onward. The lucky winners whose IDs have the most consecutive identical digits will win the lucky draw.
  • If the number of matches exceeds the number of winners, we will then further select winners based on their User IDs in ascending order (The earlier the registration time, the lower the UID number).
  • For example:
    • Assume that the last Binance Chain block hash value on the last day of this promotion period is: 3E53A755905113FD1738F0A585D65CE4AC942AAF214625512E30A07FBBA5DFA5
    • Removing the letters from the hash value gives us a string of numbers: 35375590511317380585654942214625512300755
    • The winning number is 12300755.
      • Comparing the 8 digits of all User IDs, if it matches the last 8 digits of the winning number 12300755, the user will be a winner.
      • Users whose UIDs have 7 consecutive digits that match 7 consecutive digits of the winning number will prioritize over users whose UIDs having 6 consecutive digits that match 6 consecutive digits of the winning number.
      • By analogy, if the user's UID is not matched with 6 to 8 consecutive digits, and the 5 consecutive digits are consistent with the winning number, the winner will be awarded.
      • If there is 1 winner left, suppose user A's UID is 42300790 (alignment matching 12300755), and user B's UID is 35600755 (alignment matching 12300755), then user A and user B have the same winning probability because we will then further select winners based on their User IDs in ascending order (The earlier the registration time, the lower the UID number).
