Claim 13:
14. The device according to claim 9, wherein in the step 2, the transaction verification rule comprises, for selection of a verification object: rule 1, selecting an initiating node that verifies a new transaction as the transaction acting as the receiving nodes; rule 2, backtracing according to the rule 1 by taking the transaction found by the rule 1 as a start point when there are less than two transactions that meet the rule 1, and when two parent transactions are obtained by backtracing, prioritizing direct parent transactions of a transaction at the start point; and rule 3, prioritizing the transactions that are less verified, prioritizing the transaction initiated by the transaction initiating nodes with lower credit when the transactions meet a preceding rule and are verified the same times, and prioritizing the transaction whose transaction initiation time is earlier when the credits of the transaction initiation nodes of multiple transactions are the same; verifying two transactions as the parent transactions of the new transaction when exactly two transactions meet the rule 1, and when only one transaction meets the rule 1, backtracing the transactions based on the principle of the rule 2 by taking the one transaction as a start point, and selecting, among the transactions obtained during backtracing, a transaction of meeting the requirements according to the principle of the rule 3 to form two parent transactions together with the one transaction.
