In a blockchain system, numerous nodes jointly participate in data verification and recording, and each node saves a complete blockchain ledger. When a node receives a new transaction request, it broadcasts the transaction information to other nodes, which verify the transaction after receiving the information. Once the transaction is confirmed by most nodes, it is added to a new block and then propagates to all other nodes. This  process ensures data synchronization among all nodes in the blockchain system.↵↵In addition, blockchain also adopts cryptographic principles to ensure secure data transmission and access, utilizing smart contracts to facilitate the execution of transactions and maintain the integrity of the system."}]}],"pr":"de604846a1871d826d2e3644f5d1a686dbcadb4ad1833cfec13af2ddcbb64482"}
