In the blockchain, each block contains information from the previous block, and any tampering with the previous block will cause the hash value to change, making it difficult to tamper with the data. This ensures the integrity of the data and prevents fraud."}]}],"pr":"ff3a8e13bdca7d6137f845401585fc862396b09741b4f8df1ca12c561a27040c"}
