The consensus protocol designs a method that ensures the security and consistency of the blockchain network even when malicious behavior occurs in the nodes within the network. Generally, the consensus protocol sets a threshold, allowing a certain proportion of malicious nodes to exist in the network. When the malicious  behavior of a node is discovered, it is excluded from the consensus process, ensuring that the majority of honest nodes can reach a consensus.↵↵Specifically, consensus protocols usually fall into two categories: one is stake-based consensus, such as Proof of Stake (PoS) and Delegated Proof of Stake (DPoS)."}]}],"pr":"0cc96a0d08d8b18b1c5431359494f602c1f386be44e7f3c769bcdbf36ed62b80"}
