By reaching consensus between network nodes, it prevents malicious behaviors such as data tampering and double spending, thereby ensuring the security and reliability of the blockchain. The high degree of decentralization of the consensus mechanism allows nodes to operate without relying on any centralized institution, reducing the cost of credit. In addition, consensus mechanisms have broad application value in areas such as digital currencies, smart contracts, supply chain management, and medical record management. Continuously optimizing and innovating consensus mechanisms will provide more reliable and secure technical support for the development of  the digital economy."}]}],"pr":"1e44fa6f59ce11318534b39166b80b23b7f3d082565a0cc0aa8a822fab0d244b"}
