Additionally, there are other consensus mechanisms, such as Delegated Proof of Stake (DPoS) and Practical Byzantine Fault Tolerance (PBFT). These consensus mechanisms  address data consistency and security issues in blockchain networks based on decentralization, laying the foundation for blockchain technology. Different consensus mechanisms have varying advantages and disadvantages."}]}],"pr":"6f7b588a8860bd602405cf4de803157fccf176386cb0c0b3560805f72f7a72cc"}
