Specifically, the data records in a blockchain system are jointly maintained by all nodes across the entire network, each of which stores the complete transaction history. When new transactions occur, the system incorporates them into new blocks and connects them to previous blocks through hash pointers, forming a continuously growing chain structure. This decentralized structure ensures the reliability  and security of the data.\n\nIn addition, blockchain adopts a data structure called Merkle Tree, which is used for efficient storage and verification of transaction data."}]}],"pr":"07e59c09c39235063b8caa0e7413b64fe2522e568342498906581ac7e89bd6fc"}
