During this process, each block contains a certain amount of data and information, such as transaction records, account balances, etc. As the blockchain continues to grow, versioned transactions enable new transactions to be incorporated into the latest blocks, thus achieving the sequential and continuous nature of transactions. Meanwhile, versioned transactions also ensure the security and immutability of data, as each block contains the hash value of the previous block. Once the data in a block is tampered with, it will cause the hash value to change, making it impossible for the tampered block to be recognized by the subsequent blocks."}]}],"pr":"a1e87eb5c567f72aa315d0baa8743953f2ab5281c4492f82c841aadc40bca9a9"}
