In step 303, the corresponding at least one authority of public key is searched, obtains at least one authority.
In embodiments of the present invention, authority includes at least addition node authority, replaces node authority and deletion of node authority.
After according to safeguarding that signature determines public key, since each node is stored between public key and authority in distributed account book system
Correspondence, therefore, can in node be inquired about based on public key, determine the corresponding authority of public key.Wherein, if do not looked into
Find the corresponding authority of public key, then it represents that the node for holding the public key is not to safeguard node, namely and without to node into
The maintenance received can be merchandised and abandoned by the authority that row is safeguarded, node, and continue reception and processing to other transaction.
In step 304, when at least one authority includes node maintenance authority, data are safeguarded in acquisition, to safeguarding data
Carry out data common recognition.
In embodiments of the present invention, since criminal may forge malicious data, and into distributed account book system
Node send the malicious data, and then the data of account book in node are stolen by the malicious data, therefore, work as acquisition
To after the corresponding at least one authority of public key, if at least one authority includes node maintenance authority, node, which obtains, to be safeguarded
The maintenance data carried in transaction, know together the maintenance data, if to safeguarding that data are known together successfully, continue to be based on being somebody's turn to do
Safeguard that data generate block, block is write to the block chain of account book in distributed account book system, and perform the maintenance data；If
To safeguarding data common recognition failure, then the maintenance data are abandoned, continue to and handle be sent in distributed account book system
Other transaction.Wherein, node, can be to safeguarding that data carry out signature verification, generation verification when to safeguarding that data are known together
As a result, and based on verification result generation common recognition broadcast, the broadcast that will know together is transmitted to whole nodes in distributed account book system,
The common recognition broadcast of other node-node transmissions in distributed account book system is received at the same time, to carry out data common recognition to the maintenance data.
In step 305, when detecting other nodes in distributed account book system to safeguarding that data know together successfully
When, based on data are safeguarded, block is generated, block is added in the block chain of account book, block is broadcasted to distributed account book system
Other nodes in system, so that other nodes write block, block includes at least and safeguards data.
In embodiments of the present invention, for any node in distributed account book system, when receiving distributed account book system
In system during the common recognition broadcast of other node-node transmissions, it is determined that detect other nodes in distributed account book system to safeguarding data
Reach common understanding, you can generate block based on the maintenance data, block is added in the block chain of account book, and then perform the maintenance
Data.During practical application, due to that can have fraud node in distributed account book system, and cheat node can't be to
Other node-node transmissions in distributed account book system, which are known together, broadcasts so that the quantity for the common recognition broadcast that node receives, which can be less than, divides
The number of nodes of other nodes in cloth account book system, can be that the node in distributed account book system sets default section therefore
Point quantity, the and then when node in distributed account book system is known together, node can count the common recognition broadcast that receives
Quantity of broadcast, when quantity of broadcast is more than default number of nodes, it is determined that other nodes are to safeguarding that data have reached common recognition, you can
Call back function is mounted on data-interface.Wherein, can be according to real in distributed account book system when setting default number of nodes
The number of nodes on border is configured.It is arranged to default by the 80% of number of nodes actual in distributed account book system for example, setting
Number of nodes, if distributed account book system includes 100 nodes, 80 are arranged to by default number of nodes.
It should be noted that since the node in distributed account book system can have delay in transmission common recognition broadcast, make
The common recognition broadcast of other node-node transmissions can not be immediately received by obtaining node, therefore, on each node in distributed account book system
Timer can be set, and overtime duration is set on timer.The common recognition for receiving other node-node transmissions first when node is wide
Sowing time, starts timer, and continues to the common recognition broadcast of other node-node transmissions；When the timing duration of timer reaches time-out
When long, then stop timing and receive common recognition broadcast, the quantity of broadcast for the common recognition broadcast being currently received is counted, if statistics obtains
Quantity of broadcast be more than or equal to default number of nodes, it is determined that other nodes in distributed account book system are to safeguarding that data are reached
Common recognition, based on safeguard data generate block；If counting obtained quantity of broadcast is less than default number of nodes, it is determined that distributed account
Other nodes in the system just will safeguard that data abandon, and continue to other transaction to safeguarding that data are not reached common understanding.
The mode that the embodiment of the present invention receives node and count common recognition broadcast is limited without specific.
After the common recognition to the maintenance data is successful, node can be based on safeguarding that data generate block, and block is added
Broadcasted into the block chain of account book, and by block to other nodes in distributed account book system, so that other node write areas
Block.Wherein, node when generating block, it is necessary to according to safeguard data generate so that the block chain pair in distributed account book system
This node maintenance process is recorded.
For example, with reference to Fig. 3 E, if the node in current distribution account book system is tetra- nodes of A, B, C, D, if received
To maintenance transaction in the maintenance data that carry be { Type=1, Newid=E, Height=100, Sign=XXX }, wherein,
" Type=1 " represents to add new node, and " Newid=E " represents that the node identification of the new node of addition is E, " Height=
The block of block chain is highly 100 in 100 " expression new nodes, and " Sign=XXX " represents that the desired value of record new node is XXX,
Then after tetra- nodes of A, B, C, D reach common understanding the maintenance data, each node in tetra- nodes of A, B, C, D can generate bag
Include the block of the maintenance data, and the block be broadcast to other nodes, so as to other nodes based on the block that itself generates with
The block received is compared, and when the block of itself generation is consistent with the block received, block is added to block chain
In；Meanwhile increase new node E in distributed account book system, and by any node in tetra- nodes of A, B, C, D by the area of itself
Block chain is transmitted to node E, so that the block chain in the block chain on node E and tetra- nodes of A, B, C, D is consistent.
In the case of distributed account book system interior joint is deleted, if currently the node in distribution account book system is A, B,
C, five nodes of D, E, if the maintenance data carried in the maintenance transaction received are { Type=2, Oldid=E, Height
