1. The platform will take the hash value of the last HECO block by the end of each term as the winning sequence; 

2. A user’s UID contains 10 digits at most. If a user’s UID contains less than 10 digits, “0” will be added before the first digit till 10 digits (for example, assume that the user’s UID is 12345, the adjusted UID will be 0000012345); 

3. The last 10 digits of the winning sequence will be matched with users’ UID from the first digit backward, and the lucky users with the most consecutive identical digits will receive rewards;

4. If the number of matches exceeds the number of winning positions, these users will be ranked by UID value from small to large. (the smaller the UID value, the earlier the registration time);

For example:

1. Assuming that the hash value of the last designated HECO block at 8:00 am on May 16, 2021 (UTC) is 0x95519f40a75c3f46d0426d5db908458b3d056b929d02b536c1c6d431ec94f093;

2. The winning sequence is as below by deleting the letters: 0955194075346042659084583056929025361643194093;

a. If a user’s UID exactly matches the last 10 digits “1643194093”, the user will become a lucky winner and get rewarded;

b. If the first digit of user’s UID does not match, the last 9 digits will be compared, and users whose UIDs exactly match the last 9 digits “643194093” will be lucky winners and rewarded; 

c. If the first two digits of user’s UID do not match, the last 8 digits will be compared, and users whose UIDs exactly match the last 8 digits “43194093” will be the lucky winners and rewarded; 

d. By analogy, when the last 3 digits of UID are retrieved and only 5 lucky winners will be rewarded, while there are 8 users whose UIDs match the last 3 digits of the winning sequence, such as 31093, 452093, 1233093, 98125093, 174896093, 294547093, 5678093, and 39093. These 8 users will be ranked by UID value from small to large, and users with UIDs of 31093, 39093, 452093, 1233093, and 5678093 shall be rewarded in turn.
