Fault tolerance: Consensus protocols need to have the ability to handle node failures. When a node fails, other nodes can continue to execute tasks and allow the failed node to recover data from non-failed nodes. For example, Raft and Zookeeper protocols are typical representatives of fault-tolerant consensus protocols. \\n\\n2. Byzantine fault tolerance: Consensus protocols need to address the impact of malicious nodes or unpredictable behavior. Through designing ingenious algorithms, nodes in the network can still reach consensus even when there are malicious nodes present. Byzantine fault tolerance ensures that the network remains secure and functional even when some nodes behave maliciously."}]}],"pr":"3608a92c94b6af59c3941934f87800b16bb1a44037124395cbb16807d69115a8"}
