Scalability.
In the following, this specification embodiment is introduced with a specific example referring to shown in Fig. 3 a- Fig. 3 c.
Firstly, transaction dispatcher module obtains multiple transaction from trading pit, and according to destination address pair referring to shown in Fig. 3 a
These transaction obtained are grouped, such as Fig. 3 a, it is assumed that obtain the grouping such as above-mentioned g1, g2, g3, the transaction class in each grouping
Seemingly, and different grouping corresponds to different destination addresses；It should be understood that in this example, it is related between the transaction of different target address
Property is weaker, and therefore, the correlation between grouping divided is weaker, and the Feasible degree executed parallel is higher.In this way, can be according to
Transaction dispersion in each grouping is inserted into block, it is assumed that be empty in block, then can be successively in block by group result
In be from top to bottom inserted into g1 grouping in first transaction, g2 grouping in first transaction, g3 grouping in first friendship
Easily ...；Then, second transaction in insertion g1 grouping, second transaction in g2 grouping, second friendship in g3 grouping
Easily ...；And so on, in this manner it is achieved that by with same target address transaction it is more dispersed be inserted into block,
Form transaction sequence.
Then, referring to shown in Fig. 3 b, transaction dispatcher module sorts according to the transaction formed in block, is distributed to three parallel
Transaction execution module VM1, VM2, VM3.These three transaction execution modules execute the transaction that distribution obtains parallel, it is assumed that wherein hand over
Read data status is READ []=[K1, K2, K3 ...] in the transaction implementing result of easy execution module VM1, and data shape is written
State is WRITE []=[K2, K4, K5 ...]；Read data status is READ in the transaction implementing result of transaction execution module VM2
[]=[K1, K2, K3 ...], write-in data mode are WRITE []=[K2, K7, K8 ...]；The transaction of transaction execution module VM3
Read data status is READ []=[K6, K9] in implementing result, and write-in data mode is WRITE []=[K10].When this theory
When bright book example is using read-write sequence as collision detection judgment mode, execution of trading is contemplated that in each transaction execution module
As a result reading and writing data sequence.
It is deposited by Fig. 3 c it is found that reading write-in data K2 in data K2 and transaction execution module VM1 in transaction execution module VM2
Conflicting.This is because performing write-in behaviour to data K2 again after transaction execution module VM1 is executed and read data K2
Make, data K2 at this time has occurred and that variation.And transaction execution module VM2 and transaction execution module VM1 are executed parallel when trading,
That read is original data K2, it is possible to not be the data K2 re-write, in this way, will result in transaction conflict.For class
Conflicting like transaction, this specification embodiment merges the transaction implementing result for the transaction execution module VM1 not conflicted, and
Based on merging later transaction implementing result, transaction execution module VM2 re-executes transaction on this basis, in this way,
Transaction execution module VM2 execute read data K2 operation when, reading is exactly data that transaction execution module VM1 re-writes
K2。
Finally, sorting according to transaction, merge the transaction implementing result of each transaction execution module output, and after exporting merging
Transaction implementing result.

Step 404a: the transaction dispatcher module acquires the corresponding each transaction generated of the multiple transaction execution module and holds
Row is as a result, and carry out collision detection to each transaction implementing result；If detection has conflict, 406a is thened follow the steps, it is no
Then, step 408a is executed；
Step 406a: there is the corresponding transaction execution module of transaction implementing result of conflict in the transaction dispatcher module instruction
At least one transaction in the presence of conflict is re-executed based on the transaction implementing result for having executed and not conflicted, until detection nothing
Conflict, the transaction dispatcher module sorts according to transaction merges transaction implementing result；
Step 408a: the transaction dispatcher module sorts according to transaction merges transaction implementing result；
Step 410a: the transaction implementing result after the transaction dispatcher module output merging.
By this specification technical solution, after transaction in block to be distributed to transaction execution module and is executed parallel, to friendship
