Qitmeer Network is the infrastructure of a new generation payment network based on BlockDAG technology. The MeerDAG protocol greatly improves TPS while ensuring security, decentralization and fairness. POW adopts a variety of mining algorithms to support GPU and FPGA hybrid mining to ensure network stability and fair distribution; The two-layer Meer_TOKEN asset issuance mechanism is not only regulation friendly, but also has basic value support under the premise of ensuring complete decentralization of the underlying public chain. MeerDAG of Qitmeer, deeply optimized BlockDAG based consensus protocol, could achieve high scalability while keeping high security and decentralization.
