Genesis chain (abbreviation: GSC33) is a completely decentralized digital currency payment landing solution, which has the advantages of supporting small and micro payments, instant arrival, and extremely low handling fees. The payment request and the legal currency exchange request are matched through the upper-level decision-making network, and then an efficient and secure payment channel is established by the lower-level lightning network, and finally the legal currency settlement with the merchant is completed through the payment acquirer in each place. It greatly guarantees the security, stability and sustainable development of the payment network. On the other hand, the incentive strategy of the upper network can effectively avoid the centralization tendency of the Lightning Network.
