In this embodiment, in M or K blocks, when the transaction between the financial frameworks is too frequent, the influence factor is smaller, and the weight value of the transaction amount in the block with the earlier generation time is relatively smaller. In addition, for the blocks with the number of the blocks spaced from the current block larger than K, the weight of the accumulated transaction amount value of the current block becomes 0, that is, the influence on the accumulated transaction amount value of the current block becomes 0. The calculation method can ensure that even if transaction cheating is carried out among the financial institutions, the probability of acquiring the accounting right is not greatly improved but is possibly reduced, and the maximum value of the transaction amount is not always controlled by one financial institution or a plurality of financial institutions.
And S250, determining the financial institution acquiring the accounting right in the block in the current region according to the accumulated transaction amount value of each financial institution.
In this embodiment, the accumulated transaction amount values of the financial institutions in the current block are sorted from large to small according to the accumulated transaction amount values of the financial institutions, and the financial institution with the accumulated transaction amount value ranked first is determined as the financial institution with the accounting right in the current block.
And S260, acquiring the transaction fee of the financial institution which does not obtain the accounting right in the current block, and sending the transaction fee to the financial institution which obtains the accounting right.
