The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of an electronic voting method based on a block chain according to an embodiment of the present invention. The embodiment of the invention provides an electronic voting method based on a block chain aiming at the technical problems in the prior art, which comprises the following specific steps:
In an embodiment of the present application, the blockchain network includes the electronic voting initiator node, the supervision node, an accounting node, and the voting node.
The electronic voting initiator node may be any participant node in the blockchain network, that is, any participant node in the blockchain network may serve as an initiator node of the electronic voting, and the initiator node may set qualification conditions that the voting node needs to satisfy and specific information to be voted.
The monitoring node may specifically be a database storing complete user identity information, and the monitoring node may generate the identity authentication information of the voting node according to the qualification condition of the voting node. The supervision node may specifically be a notarized third party node, which may be, for example, a database of a public security department.
The voting node may be any one or more participating nodes in a blockchain network.
Specifically, the electronic voting initiator node broadcasts electronic voting announcement information in the blockchain network, where the electronic voting announcement information includes: the system comprises voting qualification conditions, identification information of the supervision nodes, information to be voted, voting deadline and voting rules. When the supervision node receives the electronic voting notice information, the voting qualification condition is extracted from the electronic voting notice information.
And the supervision node inquires the voting nodes meeting the voting qualification in a database of the supervision node according to the voting qualification condition, and further inquires and obtains the public key and/or the block chain identification of the voting nodes meeting the voting qualification.
In step 203, the supervising node performs private key signature on the public blockchain keys and/or blockchain identifications of the voting nodes which meet the voting qualification.
And step 204, the supervising node broadcasts the public blockchain keys and/or blockchain identifications of the voting nodes which meet the voting qualification after being signed by the private key in a blockchain network.
Specifically, the public blockchain keys and/or blockchain identifications of a plurality of voting nodes meeting voting qualification broadcast by the supervising node in the blockchain network are public information, and more confidential information such as identity information of the voting nodes meeting the voting qualification is not published in the blockchain network. Accordingly, nodes such as the accounting node and the electronic voting initiator node in the blockchain network can receive the blockchain public keys and/or blockchain identifications of the voting nodes which are qualified for voting.
The embodiment of the invention broadcasts the public key of the block chain and/or the identification of the block chain of the voting node which accords with the voting qualification in the block chain network through the supervision node, so that only the voting node which accords with the voting qualification can vote, thereby effectively avoiding the problem of impersonation voting.
Fig. 3 is a flowchart of an electronic voting method based on a block chain according to another embodiment of the present invention. On the basis of the foregoing embodiment, the electronic voting method based on a block chain provided in this embodiment specifically includes the following steps:
Specifically, the electronic voting initiator node broadcasts electronic voting announcement information in a broadcast message manner in the blockchain network, and the electronic voting announcement information may include voting qualification conditions, identification information of the supervision node, information to be voted, voting deadline time and voting rules. The identification information of the monitoring node may specifically be a blockchain identification of the monitoring node in the blockchain network and identity information of the monitoring node in the real society. The information to be voted may specifically include an option of the content to be voted.
In some embodiments, after the electronic voting initiator node generates the electronic voting announcement information, the electronic voting announcement information may use its own private key to sign the electronic voting announcement information, and further, the signed electronic voting announcement information is broadcast to the block chain network.
And after the target node in the block chain network receives the electronic voting notice information, verifying the private key signature of the electronic voting initiator node.
And after the target node verifies the signature of the private key of the electronic voting initiator node, the target node extracts the voting qualification condition in the electronic voting notice information and determines whether the target node meets the voting qualification condition.
When the target node determines that the target node meets the voting qualification conditions, the target node determines that the target node is a voting node, and further, the target node broadcasts voting content in the block chain network, wherein the voting content comprises a private key signature of the target node.
The embodiment of the invention broadcasts the public key of the block chain and/or the identification of the block chain of the voting nodes conforming to the voting qualification in the block chain network through the monitoring node, so that only the voting nodes conforming to the voting qualification can vote, thereby effectively avoiding the problem of impersonation voting.
Fig. 4 is a flowchart of an electronic voting method based on a block chain according to another embodiment of the present invention. On the basis of the foregoing embodiment, the electronic voting method based on the block chain provided in this embodiment specifically includes the following steps:
When a target node broadcasts its voting content into a blockchain network, a billing node in the blockchain network can receive the voting content of the target node, wherein the voting content comprises a private key signature of the target node.
The accounting node firstly verifies the private key signature of the target node, and after the private key signature passes the verification, the accounting node can acquire the block chain public key and/or the block chain identification of the target node by inquiring a block chain account book.
In step 403, the accounting node determines whether the blockchain public key and/or blockchain identification of the target node is in a list broadcast by a supervising node in the blockchain network, wherein the list comprises the blockchain public keys and/or blockchain identifications of a plurality of voting nodes which are qualified for voting.
In this embodiment, the supervising node may store the public blockchain keys and/or blockchain identifications of the plurality of voting nodes that it queries as qualifying for a vote in a list, and broadcast the list in the blockchain network.
When the accounting node inquires the blockchain public key and/or the blockchain identification of the target node, further, whether the blockchain public key and/or the blockchain identification of the target node are included in the list broadcasted by the supervision node in the blockchain network is determined.
If the accounting node determines that the list broadcasted by the supervising node in the blockchain network includes the blockchain public key and/or the blockchain identification of the target node, the accounting node may record the voting content of the target node in a blockchain ledger. If the accounting node determines that the block chain public key and/or the block chain identification of the target node are not included in the list broadcasted by the supervising node in the block chain network, the accounting node can ignore the voting content of the target node. Meanwhile, the accounting node can also detect the voting content according to the voting rule described above, so as to ensure that the voting content of the target node conforms to the voting rule.
Optionally, the method further includes: after the voting deadline time, the accounting node determines voting results according to the voting contents of the target nodes, wherein the voting results comprise the voting contents of the target nodes; the accounting node records the voting results in a new tile in the blockchain network.
For example, after the voting deadline, the accounting node may determine a voting result according to the voting contents of the plurality of target nodes, and optionally, the voting result includes the voting contents of the plurality of target nodes. The accounting node records the voting results in a new block in the blockchain network.
Optionally, the method further includes: when the accounting node acquires the accounting right of the new block, the accounting node broadcasts the voting results to the blockchain network, so that other accounting nodes in the blockchain network verify the voting results, and the voting contents in the voting results, which are verified by other accounting nodes, are retained in the new block.
When the accounting node robs accounting right of the new block, the accounting node can broadcast the voting result to the block chain network, for example, the accounting node can broadcast the voting result to the block chain network after private key signature. Other accounting nodes in the blockchain network can verify the voting result, wherein the voting record successfully recorded in the new block in the blockchain account book is the voting result verified by the blockchain network, so that the electronic voting is completed.
The embodiment of the invention broadcasts the public key of the block chain and/or the identification of the block chain of the voting node which accords with the voting qualification in the block chain network through the supervision node, so that only the voting node which accords with the voting qualification can vote, thereby effectively avoiding the problem of impersonation voting.
