Participants (nodes) in the blockchain network jointly maintain a decentralized database. When a node experiences hardware failure or crashes, other nodes can still continue to record and verify transactions. This is because blockchain adopts consensus mechanisms such as Proof of Work (PoW) or Proof of Stake (PoS), ensuring that most nodes in the network follow the same rules, thus achieving mutual verification  and supervision between nodes.\n\nIn addition, blockchain employs data structures such as Merkle trees, which enable the entire..."}]}],"pr":"af4b5ae5dc6d3d458adbfe12da5b3a4bcfdef86a7e54422797c72748a2e70622"}
