Fault tolerance mechanisms handle node failure errors, allowing nodes to recover data from other normal nodes after a failure. Byzantine fault tolerance mechanisms are designed  to address malicious nodes or nodes with unpredictable behavior, ensuring that other nodes in the network can identify and ignore these undesirable actions. These two mechanisms together ensure that nodes in a blockchain network can operate normally and maintain the integrity and consistency of blockchain data. Common consensus protocols such as the Raft protocol and Zookeeper protocol, as well as the Bitcoin blockchain, adopt these mechanisms to ensure the normal operation of nodes."}]}],"pr":"0cf5740812f916350ea3c3f616620d65b030307c79c70cbdccdd444215dc6919"}
