Award selection rules based on the Ethereum hash value

2024-08-27 10:3201056
  • The winning number will be determined by taking the final 8 numeric digits of the last Ethereum hash value at 5:59 PM (UTC+8) on the specified day of the promotion period.
  • A user's Unique Identifier (UID), also known as "user ID", contains at most 8 digits. If a user ID contains less than 8 digits, leading zeros will be added until the user ID has 8 digits in total. For example, if a user ID is 3450923488, it will be adjusted to 03450923488.
  • We will then use the winning number to match against the user IDs starting from the first digit. Users whose user IDs have the most consecutive identical digits as the winning number will win the reward.
  • If there are more matching user IDs than available prizes, winners will be selected based on the ascending order of their user IDs. (Note: Earlier registrations have smaller user ID numbers.)
  • Example:
    • Suppose the last Ethereum block hash value on the final day of this promotion period is: 43509ATYSBD738F0A586ASH92382AAF21RSJD12E30A0712345678.
    • Removing the letters from the hash value results in a string of numbers: 43509738586923822112300712345678.
    • The winning number is 12345678.
      • Users whose user IDs match the last 8 digits of the winning number, 12345678, will be winners.
      • Users whose user IDs have 7 consecutive digits matching the winning number sequence will be prioritized over those with 6 consecutive matching digits.
      • Similarly, if a user ID does not match the last 7th to 8th consecutive digits but matches the remaining 6 consecutive digits in the winning number sequence, the user will still be considered a winner, and so forth.
      • Finally, if two user IDs match 3 consecutive digits in the winning number sequence—such as 12345666 (matching "12345678") and 12343555 (also matching "12345678")—and only one winner can be chosen, the user ID with the smaller number will be selected. Therefore, user ID 12343555 is the winner.
