Consensus mechanisms promote the security and reliability of blockchain networks, eliminating the need for nodes to trust any centralized institution. These mechanisms are applied in various 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 industries. Common consensus mechanisms include Proof of Work (PoW), Proof of Stake (PoS), and Byzantine Fault Tolerance."}]}],"pr":"5f9f7fc7cc5b5a580832f47ce12a1368bc8b139f0deb2ee096ea0f7365400885"}
