Whenever a new transaction occurs, the nodes verify the  legality of the transaction according to the consensus algorithm and ensure that the data cannot be tampered with through encryption technology. In this way, all nodes record transactions on the same ledger, avoiding centralized control and thereby improving the security of the data."}]}],"pr":"2965da97012923cb0677fee98ec3ff9bcd029f4ece907c825e9d23309214b8d0"}
