It is achieved through  protocols between algorithms and network nodes, ensuring consistency of data and transactions on the blockchain for all nodes. This prevents double spending and other malicious behaviors, maintaining the stable operation of the blockchain system. Consensus mechanisms can prevent nodes in the network from tampering with data or engaging in other malicious activities, making the blockchain even more secure and reliable. Additionally, consensus mechanisms increase the decentralization of the blockchain, eliminating the need for nodes to trust any centralized institutions, thus achieving the goals of decentralization and democratization. Consensus mechanisms are applied in various fields such as digital currencies, smart contracts, supply chain management, and medical record management."}]}],"pr":"e997303306ff81ca3936761dcd62c196dc663731d92c5e8a35fcea56f11bae45"}
