AppendTx messages typically contain detailed information about the transaction, such as the sender, recipient, amount, etc. When the blockchain system receives an AppendTx message, it combines the transaction data in the message with the current block, ensuring that blocks are generated in chronological order. The advantage of this approach is that it ensures the integrity and rigor of  the blockchain database, as each new block contains information from the previous block. Once a block is added to the end of the blockchain, its data records cannot be changed or altered."}]}],"pr":"4c437ec872fef6ed5af73d5a2eab857b05dcdf69bceffa2b009e4fd79b5071b7"}
