Different consensus algorithms achieve different balances between security, consistency, and availability, thereby affecting the stability and security of the entire blockchain network. For example, consensus algorithms such as Proof of Work (PoW) and Proof of Stake (PoS) have certain limitations in ensuring the security of blockchain.\n\nThe PoW algorithm ensures blockchain security by requiring nodes to compete for block production by solving complex mathematical problems. However, the PoW algorithm has high energy consumption and the mining difficulty keeps  increasing, resulting in only a few nodes with strong computing capabilities being able to participate in the mining process."}]}],"pr":"15408cac6480f8edb60be9b5f5d6d87c0b378c3f34bd5f8ad118d097bc9c2b1f"}
