GFCC is a public blockchain system based on a hybrid consensus mechanism of DPOS+POC, aiming to build a credible ecosystem for myriad application scenarios and hundreds of millions of people. This project focuses on improving the excessive centralization problem in DPOS by innovatively proposing a hybrid consensus mechanism of DPOS+POC, making substantial optimizations in node voting and final confirmation of transactions. At the same time, through a credit reward and punishment system and voting mechanism, it can significantly improve transaction efficiency and resource consumption issues under the condition of equal security.
