Description

Blockchain counting system based on digital currency

The present invention relates to a counting system, and more particularly to a blockchain counting system based on digital currency.

The current method of voting by paper ballot usually requires manual procedures such as ticket inspection, ticketing, and counting, which is not only time-consuming but also impossible to fully guarantee the fairness of the counting result. However, if the result of the counting of the votes is questioned and the ticket must be re-inspected, the re-inspection work must be carried out with additional manpower, which will increase the labor cost. On the other hand, for a large number of votes (requiring re-inspection) It is also very troublesome to keep and collect.

In order to solve the above problems, an electronic voting (e-voting) method using an electronic system has been proposed. However, this electronic voting method is still unable to effectively avoid human error, hardware or software attack, errors in the counting program, etc., so that the fairness of the counting result cannot be ensured.

Therefore, there is still much room for improvement in the existing counting method.

Accordingly, it is an object of the present invention to provide a blockchain counting system based on digital currency that overcomes the shortcomings of the prior art.

Thus, the present invention provides a block currency counting system based on digital currency for calculating a cumulative number of votes obtained by each of a plurality of selected items during a predetermined voting period. The blockchain counting system includes a plurality of computer nodes interconnected via a communication network. The computer node of each blockchain counting system includes a communication module, a storage module, and a processing module electrically connected to the communication module and the storage module, wherein the storage module is configured with a plurality of corresponding Each of the storage units stores at least one historical data block, wherein each of the storage units includes at least one amount of money indicating a corresponding historical digit currency amount, and indicating one of the voting objects. The history of the person accumulates the votes of the votes.

For each computer node, when the communication module receives the current voting data indicating at least one selected object and one digital currency amount during the predetermined voting period, the processing module is based at least on the communication module. The digital currency amount indicated by the current voting data, and a first weight value related to the date the communication module receives the current voting data, obtaining a new number of votes corresponding to the selected object . The processing module stores one of the most recent historical data of the at least one historical data block stored according to the number of new tickets and one of the storage units corresponding to the selected object and the storage unit as a target storage unit The historical accumulated votes indicated by the block of the ticket information contained in the block, resulting in a current cumulative number of votes corresponding to the selected object. The processing module generates a data block according to at least the digital currency amount of the pen and the current accumulated number of votes of the pen, the data block at least containing the amount of money indicating the amount of the digital currency of the pen, and indicating the current accumulated ticket of the pen The number of votes obtained, and the encrypted data block is newly stored in the target storage unit as a current data block related to the current voting data and the selected object. The processing module uses the communication module to transmit the current data block of the pen to other computer nodes, so that the other computer node adds the current data block to the target storage after successfully verifying the current data block. unit.

The effect of the novel is that each computer node of the blockchain counting system has stored all the historical data blocks corresponding to each of the voting objects by using the blockchain technology, and receives the current data related to the digital currency. When voting data, the current data block corresponding to the current voting data is generated, and the current data block is stored by using the blockchain technology, and the current data block is transmitted to other computer nodes, thereby All computer nodes update the current data block synchronously. Therefore, if the data of all computer nodes is not verified, all the historical data blocks stored in any computer node will be difficult to be tampered with or deleted, thus ensuring the fairness of the counting results.

Referring to Figure 1, an embodiment of the novel bitcoin-based blockchain counting system 100 is adapted to calculate a cumulative number of votes obtained by each of a plurality of selected items during a predetermined voting period. The digit currency can be a cryptocurrency, such as Ether, but not limited to this, and the digit currency can also be other cryptocurrency, virtual currency or token. For the sake of clarity, the present embodiment only takes three voting items as an example (hereinafter referred to as a first voting item, a second voting item, and a third voting item, respectively), but in actual use, it is not limited to this example. In addition, the first to third voting items may differ depending on the subject matter of the different voting activities. For example, if the subject of the voting activity applied is to vote for a popular online star, the first to third voting objects may respectively represent three different online stars. However, in the application of other different voting campaign topics, the voting objects may also be corresponding real/virtual characters, goods/items, or policies/topics related to public affairs, and the like.

The blockchain counting system 100 includes a plurality of computer nodes 10, 10' (only three are depicted in Figure 1) interconnected by a communication network 200, such as the Internet or an Ethernet network. In this embodiment, each computer node 10/10 ′ can be implemented as a computer device such as a desktop computer, a laptop, a tablet computer, or a smart phone, and can include a storage module 1 and a communication module. 3. A processing module 2 electrically connected to the storage module 1 and the communication module 3.

For example, as shown in FIG. 2, for each computer node 10/10', the storage module 1 can be configured with, for example, three storage units 11, 12, 13 respectively corresponding to the first to third voting objects. And the historical configuration of the storage module 1 is as follows: the storage unit 11 corresponding to the first voting object stores, for example, only one historical data block 111 (also as a recent historical data block); corresponding to the second The storage unit 12 of the voting object stores, for example, three historical data blocks 121-123 (where the historical data block 123 also serves as the most recent historical data block); and the storage unit 13 corresponding to the third voting object is stored with The five historical data blocks 131 to 135 (where the historical data block 135 is also used as the recent historical data block), but not limited to this example. Each of the historical data blocks 111, 121-123, 131-135 may include, for example, an amount of money indicating a corresponding historical digit currency amount, and a history indicating one of the first to third voting objects. The ticket information of the accumulated number of votes, and the date and time data indicating the date and time when the computer node 10/10' received the corresponding historical voting data.

Referring again to FIGS. 1 and 2, in use, when a queryer wants to query the blockchain counting system 100 for storage corresponding to one or more selected items (eg, the first and third voting items, If the relevant ticket information is not limited to this example, the inquirer can use a user terminal such as a computer device or a smart phone (not shown) to query the votes of the first and third voting objects. The Internet 200 is transmitted to any of the computer nodes 10. For example, if the user sends the ticket query to the computer node 10', the processing module 2 receives the ticket from the user terminal via the communication module 3 for the computer node 10'. In the inquiry, the ticket information (as the inquiry ticket information of the first vote object) contained in the (recent) history data block 111 stored in the storage unit 11 and stored in the storage unit in response to the ticket inquiry The ticket information contained in the (recent) historical data block 1 of 13 (the polling information as the third vote object) is transmitted to the user terminal by the communication module 3 for display, so that the queryer The current accumulated number of votes of the first and third voting objects may be obtained by the inquiring ticket information of the first voting object displayed on the using end and the inquiring ticket information of the third voting object.

In the case of using the voting example of the above-mentioned Internet popular star, when a voter wants to participate in the voting activity during the predetermined voting period, in the present embodiment, the voter can utilize a connection to the communication network 200. The computer device (not shown) transmits the current voting data to any of the computer nodes 10, 10'. In this embodiment, the current voting data may indicate an object to be voted, a digital currency amount, and a voter attribute of the voter, wherein the voter attribute corresponding to the voting activity example of the popular star of the Internet This may include the rank of the voter's title (for example, the first rank representing the general public or the second rank representing the professional review), but not limited to this. However, in other implementations, the current voting material may also indicate only a selected item and a digital currency amount.

Hereinafter, with reference to FIG. 1 to FIG. 4, in detail, in the case where the above-mentioned computer device transmits the current voting data to, for example, the computer node 10', in the present embodiment, how the point brain node 10' is for the current The voting data is executed by a counting procedure. The counting procedure includes the following steps S31 to S35.

In step S31, the processing module 2 receives the current voting data from the computer device by the communication module 3. For example, the desired voting object indicated by the current voting material and the digital currency amount are divided into the second voting object and an ethyl currency amount, and the voter attribute indicated by the current voting material includes Represents the second rank of professional review, but not limited to this example.

Then, in step S32, the processing module 2 is based on the amount of the Etoken currency indicated by the current voting data, a first weight value related to the date when the communication module 3 receives the current voting data, And a second weight value related to the voter attribute indicated by the current voting material, obtaining a new number of votes corresponding to the selected object. It should be noted that, in this embodiment, the first weight value may be positively correlated with a day difference between a voting deadline of the predetermined voting period and a receiving date of the current voting data, and the second weight value The system is positively related to the title level. For example, as in the conditions specified below: the Ethylene Amount 40 can represent a vote, and the first weight value = (the difference between the date of the vote and the date of receipt of the current voting material) ́ 0.1, the second weight value corresponding to the first level included in the voter attribute is 1, and the second weight value corresponding to the second level included in the voter attribute is 2 (but not This example is limited, and the exchange relationship between different types of digital currency and the number of votes may be different. For example, when the digital currency is bitcoin, the bitcoin amount 10 may represent one vote), if the current voting material is When the indicated amount of the Ethereum is 800 and the difference between the date of the voting and the date of receipt of the current voting data is 4 days, the pen obtained by the processing module 2 corresponds to the second selected object. Number of new votes = (800/40) ́ first weight value ́ second weight value = (800/40) ́(4 ́0.1) ́2=16.

Therefore, it can be concluded from the above-mentioned normative conditions that the closer the voting day is to the voting deadline, the smaller the number of votes will be, and vice versa. In addition, the vote for the popular star of the Internet is due to the second rank of the professional review. Corresponding to a larger second weight value, this will result in a more accurate result of the vote, which means that professional voters have a greater influence on the results of the vote. In addition, in another embodiment, the number of the new votes may be the amount of the E-coin indicated by the processing module 2 according to the current voting data and related to when the communication module 3 receives the current voting data. The date of the first weight value is calculated under the calculation.

Then, in step S33, the processing module 2 is based on the number of new tickets and the storage unit 12 (hereinafter also referred to as the target storage unit 12) corresponding to the second voting object in the storage module 11. The stored accumulated number of votes indicated by the received ticket data contained in the (recent) historical data block 123 generates a current cumulative number of votes corresponding to the desired selected item. For example, in the case of the example of the above step S32, if the historical accumulated ticket number indicated by the (recent) historical data block 123 is 3200, the processing module 2 generates The current cumulative number of votes is 3216 (= 3200 + 16).

Then, in step S34, the processing module 2 generates a data block according to the pen currency amount, the current accumulated number of pens, and the date and time when the computer node 10' receives the current voting data. The data block not only contains the amount information indicating the amount of the digital currency, the ticket information indicating the current accumulated number of votes, but also the date and time information indicating the date when the current voting data is received and the time. And using existing blockchain encryption techniques, such as hash algorithm, PKI public-private key encryption technology, UTXO (Unspent Transaction Outputs) mechanism, etc., to encrypt the generated data block, and the encrypted data area The block is newly stored in the target storage unit 12 as a current data block 124 (see FIG. 4) related to the current voting data and the desired voting object.

Finally, in step S35, the processing module 2 transmits the current data block 124 to the other computer nodes 10 by the communication module 3, so that the other computer nodes 10 succeed in utilizing the existing blockchain decryption technology. After verifying the current data block 12, the current data block 124 is added to a target storage unit 12 of the other computer node 10 corresponding to the second vote object. Thus, the storage modules 1 of the computer nodes 10, 10' can be synchronized, as shown in FIG. At this point, the counting procedure is completed.

It is worth mentioning that if the current data block is tampered with by the malicious attack or invasion of the computer node 10', the falsified current data block cannot be successfully verified by other computer nodes 10, so Ensure the fairness of the counting results.

Incidentally, if the current voting data is transmitted to another computer node 10, the computer node 10 can still achieve the synchronization update of all the computer nodes 10, 10' for the current data block according to the above steps S31 to S35. .

In summary, each computer node 10 of the blockchain counting system 100 of the present invention has stored all historical data blocks corresponding to each of the voting objects using the blockchain technology, and receives the relevant digital currency. When the current voting material is generated, the current data block 124 corresponding to the current voting data is generated, and the current data block 124 is stored by the blockchain technology, and the current data block 124 is transmitted to other computers. Node 10, whereby all computer nodes 10, 10' can be synchronized for the current data block of the pen. Therefore, if all the data nodes 10, 10' are not verified, all the historical data blocks 111/121~124/131~135 stored in any computer node 10/10' will be difficult to be tampered with or deleted. It is indeed possible to ensure the fairness of the results of the counting of votes, so it is indeed possible to achieve the purpose of this new type.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
