DPoS: Delegated Proof of Stake

DPoS - Delegated Proof of Stake. In order to pursue efficiency, DPoS sacrifices the decentralized nature. Due to the super node's processing power being very strong, the overall system is fast and validation efficiency is very high. However, centralization is prevalent while using this mechanism. Due to the different channels of communication, the super node has the strongest ability to spread on the market. Ordinary nodes have no bookkeeping rights and are forced to be represented by super nodes. In this case, conflicts can form between rights and interests. And decisions end up based on the interests of select individuals.

1. Decentralized only on the outside. Similar to a presidential election: one person, one vote, and each person may be elected as the president. However, because the barrier to entry is too high, the information distribution channel is limited, and ordinary users join the competition and the probability of victory is almost zero, making the super node become a few people's games.

2. Agency problems. Having a president does not mean that the interests of the country take the lead. When the interest of the president conflicts with the interests of the country, will the president really sacrifice his or her personal interests for the benefit of the country?

3. Very suitable for new blockchain projects but also very dangerous. The super-nodes in the new project are very powerful and for a long time, all super-nodes are in the hands of only one person.
