The Genesis Chain (GSC33) is a fully decentralized digital currency payment solution that supports micro-payments, instant transactions, and extremely low fees. By matching payment requests and fiat currency exchange requests through the upper-level decision-making network, and establishing efficient and secure payment channels via the lower-level Lightning Network, it ultimately completes fiat settlements with merchants through local payment acquirers. This ensures the security, stability, and sustainable development of the payment network. On the other hand, the incentive strategy of the upper-level network can effectively avoid the centralization tendency of the Lightning Network.
