Each block  contains the hash value of the previous block, forming a chain-like structure. Once the data in a block is changed, it will cause subsequent blocks to be invalidated, making it difficult to tamper with data records. This ensures that once data is recorded on the blockchain, it cannot be easily modified or tampered with, providing a reliable foundation for information security."}]}],"pr":"77d8b6896fbce9c4677e98ed0ded2fcfac3908ce7da252c52fcf532a45a2f7c3"}
