The mainstream consensus algorithms currently include Proof of Work (PoW), Proof of Stake (PoS), and Delegated Proof of Stake (DPoS). Taking Proof of Work (PoW) as an example, this algorithm ensures node participation by having them calculate hash values to solve complex mathematical problems. The higher  the difficulty, the smaller the probability of obtaining rewards for the nodes. This algorithm has the advantage of high security, but its drawback is significant computational cost and energy consumption. In contrast, Proof of Stake (PoS) bases node participation on the amount of tokens held by each node."}]}],"pr":"8cfad894f4adaba6622cf88bb8e9254bd3d24774e5cb59e0f2323b4f79609192"}
