Cluster sequence is to handle it, to generate the transaction cluster sequence of block.Target transaction cluster sequence may include at least two
Transaction cluster.Each transaction cluster is for generating a block.Transaction cluster may include destination number transaction.Destination number can be
The predetermined quantity of technical staff, or determined based on predetermined block capacity and the data volume of each transaction
Quantity out (the sum of the data volume of each transaction in transaction cluster is less than or equal to block capacity).
In practice, the transaction in block chain field refers to fund going to another user from a user, in turn, transaction
Two attributes are generally included, are respectively output and input.Input refers to the input side of fund, and output refers to the reception of fund
Side.
It should be noted that in order to express easily, the disclosure will trade and the generated transaction data of transaction is referred to as handing over
Easily.It can be appreciated that actual transaction instruction is movement, and during being packaged transaction to generate block, the reality that is packaged

As an example, transaction cluster A includes transaction a " first is given to the fund that the second amount of money is 10 "；The B that trades includes that " second turns transaction b
The fund for being 10 to the fourth amount of money ".If the original state of second is no fund, the execution for the b that trades depends on the execution of transaction a,
I.e. transaction a needs execute before the b that trades, and otherwise, transaction b will be unable to execute.Here, transaction a is both the preposition dependence of transaction b
Transaction.
In practice, for preposition dependence transaction and the transaction with dependence, the preposition output for relying on transaction is usual
For the input of the transaction.Referring to above-mentioned example, transaction a is that the preposition dependence of transaction b is traded, and exporting for a that trades is defeated with transaction b
Enter identical, is all second.
In general, block chain node can calculate encrypted result for effective transaction, and then it is wrapped into time zone block.Existing skill
In art, in order to reduce a possibility that invalid transaction is packed into block, for belonging to the transaction of different transaction clusters, usually press
Sequence calculates encrypted result.Such as target transaction cluster sequence is " transaction cluster A；Trade cluster B ", then general first to calculate in transaction cluster A
Then the encrypted result of transaction calculates the encrypted result of the transaction in transaction cluster B again.And in practicing, in adjacent transaction cluster
Dependence is not present in transaction mostly.For the transaction of dependence is not present, and there is no the need for sequentially calculating encrypted result
It asks.Therefore, for, there is no the preposition transaction for relying on transaction, the disclosure can directly determine the friendship in target transaction cluster sequence
The encrypted result computational efficiency of the transaction in target transaction cluster sequence can be improved with this in easy encrypted result, in turn, can be with
