Firstly, nodes in the blockchain network (also known as participants or miners) regularly broadcast transactions and block information to ensure that all nodes have the same data. When  a node experiences a hardware failure or crashes, other nodes can still continue processing transactions and building new blocks.\n\nSecondly, blockchain employs consensus mechanisms such as Proof of Work (PoW) or Proof of Stake (PoS) to ensure the security and consistency of the network. Under these consensus mechanisms, nodes need to complete a certain amount of computation to participate in the validation and confirmation of transactions and block generation."}]}],"pr":"82df31536d9fa33a8f9003ba1b6e0fecb4c53320ab5ebedcbfe248507487f631"}
