A mass commercial implementation of crypto economy which means a huge trading pressure. To efficiently carry a huge amount of trading demand, a blockchain system must provide strong performance firstly. To achieve this, you need set higher requirements on the whole node, such as configuring better hardware machines, larger RAM, more stable network, faster NET, lower latency, etc. Obviously, the high threshold of whole node will result in a decrease in the amount of stable Block Producers (BPs). If the POS mechanism is adopted in such a blockchain system, the system will quickly converge to centralized. In order to strike a balance between the high performance and decentralization, the DPOS consensus algorithm is undoubtedly the best choice at the moment, as well as the best settlement for governing small quantity of nodes.
