The first object cryptographic Hash answered；Then construction records the target transaction of the first object cryptographic Hash, and the target transaction is sent
Corresponding node (connecting the server corresponding to the notary organization of the block chain) in block chain, wherein, the choosing of node
Take including following three kinds of modes：
Mode one
Select corresponding according to region or preference, or system strategy (for example authority, according to node, historical traffic)
Transaction can be sent to the default node by node as default node, user.
Mode two
System is random or selects preset number node according to preset strategy, used as node group.User is multicasted to transaction
The node group, all nodes in the group all record target transaction.After Preset Time is reached or target transaction number of times reach it is pre-
If after number of times, default node is elected from node group according to factors such as the transaction counts of required expense, user's evaluation of estimate or record.
Mode three
Transaction is broadcast to all nodes, each nodes records target transaction by user.After Preset Time is reached or target hand over
Easily number of times is reached after preset times, according to factors such as the transaction counts of required expense, user's evaluation of estimate or record from node group
The default node of election.
When information satisfaction first of the target transaction in target block chain is pre-conditioned, target transaction is sent to into block
Other nodes in chain in addition to the default node.For example, the target block chain is used to connect each regional institute of notary organization
Corresponding server, and default node is the server corresponding to the notary organization in A areas, when target transaction is in block chain
Time reaches Preset Time, or transaction count of the target transaction in block chain is when reaching preset times, by target transaction
The server being sent in block chain corresponding to other the regional notary organization in addition to the A is regional.
Server corresponding to other regional notary organization after the target transaction is received, in the target transaction number
According to accuracy initiate checking, if the verification passes, then other regional notary organization are recognized the first mesh in the target transaction
The effectiveness of mark cryptographic Hash, then send confirmation to the corresponding server of notary organization in A areas.When the notary machine in A areas
When the confirmation that the corresponding server of structure is received reaches the first preset number, then it is assumed that other areas are with A areas with regard to the target
The effectiveness of first object cryptographic Hash is reached common understanding in transaction, then the target transaction is stored in corresponding to the notary organization of A areas
Server.So as to, multiple nodes that notarization servers are provided are realized to saving the common supervision of data from damage, improve data guarantor
Full safety, and then realize the foundation of trans-regional trust common recognition system.
It should be noted that being (such as to reach when the number of transaction stored in default node memory pond reaches the 3rd preset number
During to 1000), the transaction that can pass through storage is enough by a new block, and block is connected in target block chain.
For example, in the present embodiment, (i.e. transaction amount reaches when the transaction count in default node memory pond reaches 100
When 100), using this 100 transaction as target transaction, and other nodes in target block chain are sent to, so that target area
Other nodes in block chain confirm to this 100 transaction.When 10 aforesaid operations are carried out, make what is be identified in default node
When transaction amount reaches 1000 (when i.e. transaction amount reaches 1000), then the transaction that can pass through storage is enough by a new area
Block, and block is connected in target block chain.
The beneficial effects of the present invention is：After the default node being sent to target transaction in target block chain, and
Directly do not store, but when information of the target transaction in target block chain meet first it is pre-conditioned when, send it to area
Other nodes in block chain, when the confirmation that multiple other nodes send is received, just store target transaction, so as to realize
Multiple nodes improve the safety that data are saved from damage to saving the common supervision of data from damage.
In one embodiment, as shown in Fig. 2 the determination process of default node can be implemented as following steps S201-
S202：
In step s 201, each node is calculated according to the weighted value and historical traffic of each node in target block chain
Score value；
In step s 201, score value highest node is determined for default node.
In the present embodiment, according in target block chain, the weighted value and historical traffic of each node calculate each node
Score value.The weighted value can be determined according to factors such as region, preference or node authorities.According to the weighted value and section of node
Score value of the product of point historical traffic as the node.
Using score value highest node as default node.
The beneficial effects of the present invention is：According to the scoring in the weighted value and historical traffic of node with calculate node
Value, so as to determine the default node of the condition of best suiting by many index, the default node for making selection more conforms to objective need
Ask.
In one embodiment, as shown in figure 3, the determination of default node can be implemented as following steps S301-S303：
In step S301, the second preset number node is used as group of destination nodes in acquisition target block chain；
In step s 302, all nodes target transaction being sent in advance in node group；
In step S303, when information satisfaction first of the target transaction in target block chain is pre-conditioned, it is determined that section
The second pre-conditioned node is met in point group to preset node, wherein, second is pre-conditioned including following at least one condition：
The transaction count of required network minimal, user's evaluation of estimate highest and record is most.
In the present embodiment, obtain the second preset number node in target block chain and, as group of destination nodes, target is handed over
The all nodes being easily sent in advance in the node group, when the information in the target block chain that the target transaction is located meets first
(for example, the transaction count of target transaction reaches preset times, or time of the target transaction in block chain reaches when pre-conditioned
During to Preset Time), elect default from node group according to factors such as the transaction counts of required expense, user's evaluation of estimate or record
Node.For example, the node of required network minimal can be selected as default node, what is so can saved required for data are saved from damage opens
；User's evaluation of estimate highest node can also be selected as default node, the safety that data are saved from damage can be so improved；May be used also
Using the most node of selection transaction count as default node, so that the data saved from damage are more difficult being changed, also improve
The safety that data are saved from damage.
It should be noted that being not limited in the friendship of network minimal, user's evaluation of estimate highest and record needed for above-mentioned selection
The easily most node of number of times is used as default node.Default node can also by other means be determined：
For example, the performance of all nodes in node group can be obtained, using joint behavior highest node as default node.
Again for example, data to be saved from damage can also be further determined that after the performance of all nodes in node group is obtained
Size, when the data volume of data to be saved from damage is less, by the minimum node of performance data also can be in a short period of time completed
Save from damage, then the minimum node of performance is selected as default node, so as to avoid waste and the equipment of calculating high-performance equipment power
Loss, it is generally the case that the value of high-performance equipment is much higher, thus, data volume is completed using low-performance equipment less
Data are saved from damage, equivalent to saving cost.
Again for example, it is contemplated that the section that effect may be low better than required expense of saving from damage to required costly node to data
Point, thus, it is also possible to costly node or required expense highest node are used as default node needed for selecting.
It is, of course, also possible to choose more parameters to choose default node, here is not repeated one by one.
