It prevents double spending and other malicious behaviors by reaching consensus between network nodes. Consensus mechanisms make blockchain more secure and reliable, and enable collaboration between nodes in a decentralized environment. They can be applied to fields such as digital currencies, smart contracts, supply chain management, and medical record management, providing reliable technical support for the development and application of these areas. Currently, mainstream consensus mechanisms include Proof of Work (PoW), Proof of Stake (PoS), and Byzantine Fault Tolerance."}]}],"pr":"907a965be8f0a1fef5814afef1522e5d0c70de55bff620952dc54aeca0025b82"}
