In a blockchain system, data is stored across multiple nodes, each with a complete ledger. Every time data is updated or a transaction occurs, all nodes synchronize and validate the information. This decentralized structure ensures data consistency because no single node can tamper with the data, unless all relevant nodes are simultaneously tampered with.\n\nAdditionally, cryptographic  principles in blockchain technology secure the data, preventing unauthorized access and tampering. Smart contracts are used to regulate and facilitate transactions, ensuring that they are carried out securely and transparently."}]}],"pr":"b5a6a1e2d1ff0e440db751e94b455ecdcd895e22020a15dc4080b073dabe9294"}
