Once the data in a block is changed, it will cause the hash value of the subsequent blocks to change. This feature ensures that once the data is entered into the blockchain, it cannot be tampered with or deleted, maintaining the credibility of the electronic voting system."}]}],"pr":"21445759adb12ece5816cb057a3066afa012d04f80ea71912c3674d0aa7bde25"}
