On sub- ballot system, which is characterized in that the block chain electronic voting system includes the privately owned chain of block chain, and the block chain is privately owned
Chain includes first node and second node, the method includes：
The vote information of first node acquisition voter；
First node generates voting records according to the vote information；
First node is sent to second node after being digitally signed the voting records, wherein the first node
It is node different in the privately owned chain of block chain from the second node.
In some possible realizations, the voting records include following record information：
The account of the voter；
The polling hours of the voter；
Candidate information.
In some possible realizations, the voting records are sent to second node by the first node, including：
The first node determines the hashed value that the last item records in the privately owned chain of block chain；
The first node is sent out after being signed using digital signature technology to the voting records according to the hashed value
Give the second node.
In some possible realizations, first node described in second section uses digital signature according to the hashed value
Technology is sent to after the second node after signing to the voting records, the method also includes：
The second node determines whether the first node is legitimate node；
If it is determined that the first node is legitimate node, then the second node is digitally signed the voting records
Verifying；
If ballot angle record to be shared to other residues in the privately owned chain by the digital signature authentication
Node.
In some possible realizations, if the second node determines that the first node is illegal node, institute is abandoned
State voting records.
Second aspect of the present invention provides a kind of block chain electronic voting system, which is characterized in that the block chain electronics is thrown
Bill system includes the privately owned chain of block chain, and the privately owned chain of block chain includes first node and second node；
First node, for obtaining the vote information of voter；Voting records are generated according to the vote information；It will be described
Voting records are sent to second node, wherein the first node and the second node be in the privately owned chain of block chain not
Same node.
In a kind of possible realization, the first node is used to the voting records being sent to second node, including：
The first node is used for：
Determine the hashed value that the last item records in the privately owned chain of block chain；
According to the hashed value, described second is sent to after signing using digital signature technology to the voting records
Node.
In a kind of possible realization, the second node is used for：
Determine whether the first node is legitimate node；
If it is determined that the first node is legitimate node, then verifying is digitally signed to the voting records；
If the voting records are shared to other residues in the privately owned chain and are saved by the digital signature authentication
Point.
In a kind of possible realization, which is characterized in that the second node is also used to：
If it is determined that the first node is illegal node, then the voting records are abandoned.
A kind of computer product is provided in the third aspect of the embodiment of the present invention, the computer program product, which is able to achieve, to be held
The function that any one of row aforementioned first aspect method is realized.
First aspect of the embodiment of the present invention provides a kind of electronics based on block chain it can be seen from above-mentioned technical proposal
Voting method is applied on block chain electronic voting system, which is characterized in that the block chain electronic voting system includes block
The privately owned chain of chain, the privately owned chain of block chain include first node and second node, the method includes：First node, which obtains, to be thrown
The vote information of ticket person；First node generates voting records according to the vote information；First node by the voting records into
Second node is sent to after row digital signature, wherein the first node is the privately owned chain of block chain with the second node
Middle different node.It can be seen that the present invention will vote on the privately owned chain of block chain, so that voting records and ballot knot
The information such as fruit have stronger anti-tamper characteristic, and each voting records can trace, and effectively improve the fairness of ballot.
