| Abstract: |
A method for automatically providing a cryptocurrency to a recommender using social networking service (SNS) propagation includes an SNS friend recommending step, a new registration step, a reward rate determining step, a rewarding step, a transaction processing step, and a retransaction-based transaction processing step. The reward rate determining step includes the steps of determining a membership grade of a blockchain member recommended by the blockchain membership node according to the number of SNS friend IDs recommended and determining a reward rate for the blockchain member according to the determined membership grade. In the reward rate determining step, the membership grade of the recommended blockchain member rises as the number of the SNS friend IDs recommended by the blockchain membership node increases. When an SNS friend recommended by the blockchain membership node recommends another SNS friend, a weight is assigned to the membership grade of the blockchain member first recommended. |
