Description

Blockchain operating device and its operation method {OPERATING APPARATUS FOR BLOCK CHAIN, AND CONTROL METHOD THEREOF}

The present invention relates to a technology for selecting a generation node, which is a node with the authority to create blocks, by considering the location of the node in a blockchain network environment where Delegated Proof of Stake (DPoS) is applied.

Bitcoin was created in 2000 based on Satoshi Nakamoto's paper. Bitcoin, with its decentralized and autonomous ecosystem, has been used for more than 10 years.

The core of the underlying technology is a method of creating an untamperable distributed ledger through a P2P network. Bitcoin's autonomous system, which cannot be manipulated by the outside, solves mathematical problems at a certain time called Proof of Working for system stability. Cryptocurrency can be supplied in return for mining by solving.

This demonstrated the possibility of a cryptocurrency system and provided a clue to the supply of distributed ledgers and cryptocurrency, but it was only a primitive form in terms of applicability of applying distributed ledgers to various fields.

Accordingly, Ethereum, announced by Vitalic Buterin in 2014, has provided the flexibility to apply Ethereum in various fields based on smart contracts.

In other words, it provides standard technologies such as dAPP and ERC20 that can be integrated into the Ethereum cryptocurrency system no matter what application field creates a new cryptocurrency.

The cryptocurrencies that emerged after Bitcoin and Ethereum, called the first and second generation cryptocurrencies, respectively, attempted to improve the authentication problems and versatility seen in existing cryptocurrencies.

Here, the authentication problem can be interpreted as a problem of mining costs and opportunity costs related to authentication time, and an attempt to solve this problem is Proof of Stake.

The proof-of-stake method allows block creation after a certain time if the coinage, which is defined as a function of stake and time, is high.

Equity is the amount of cryptocurrency contained in an individual wallet among all issued cryptocurrency, so the higher the amount of cryptocurrency held, the higher the probability of mining.

This method is based on the fact that even if a small number of stakeholders with a large amount of shares certify block creation through majority rule, their interests will not be harmed.

In addition, there are claims that the majority rule authentication method through stakeholders is similar to the Proof of Work method used by Bitcoin and other mining companies, which are dominated by a small number of mining companies.

However, the Proof of Work or Proof of Stake methods for distributing newly supplied digital claims, such as cryptocurrency, depend on computer power or the size of the stake, respectively, which is why they were born. In general, Proof of Work is winner-takes-all, and Proof of Stake has a structure in which more shares are always distributed to minorities with large amounts of shares.

Therefore, there is a structural problem in that general individuals with a small stake or blockchain devices with low computing power are excluded from the distribution of newly supplied cryptocurrency, which is the compensation for creating a new blockchain. Additionally, this proof method quickly creates a new blockchain. There is also a structural problem in that it takes time to create and propagate it to the entire network.

Meanwhile, in order to make up for the above shortcomings of Proof of Work or Proof of Stake, stake holders vote for representative nodes and receive compensation accordingly. Proof of Stake was proposed.

For example, EOS has dramatically reduced the proof costs incurred in the system by reducing the number of proof nodes through the delegated stake method (DPoS).

In other words, in the representative delegated stake method (DPoS), the number of nodes that generate blocks is limited in advance and blocks are generated once in a randomly generated order, thereby shortening the time for the generated blocks to be recognized. There is.

However, in the case of Delegate Stake (DPoS), the number of nodes with the authority to create blocks is predetermined and the number is not large, so there is a possibility that nodes can be easily contaminated, such as data manipulation due to external hacking, etc., especially in blocks. If the nodes that generate are concentrated locally, the risk of such contamination can be seen as even greater.

Accordingly, the present invention proposes a new method for selecting a node with the authority to create blocks in a blockchain network environment where Delegated Proof of Stake (DPoS) is applied.

The present invention was created in consideration of the above-mentioned circumstances, and the goal to be achieved by the present invention is to block blocks by considering the location of the node in a blockchain network environment where Delegated Proof of Stake (DPoS) is applied. The purpose is to select a creation node, which is a node with the authority to create.

A blockchain operating device according to an embodiment of the present invention for achieving the above object includes a processor that processes operations related to the selection of a generation node with authority to create blocks in a blockchain network; and a memory storing at least one command executed through the processor, wherein the at least one command is configured to select the generation node from the representative node for a stake node holding a stake in the blockchain network. Provision order providing a voting environment for voting; and a selection command for selecting the generation node based on at least one of the number of votes received by the representative node in the voting environment and the location of the representative node.

Specifically, the selection command divides the offline area where all representative nodes are distributed in the blockchain network into selection areas corresponding to the required number of generation nodes, and the number of votes of the representative node for each divided selection area is given priority. Depending on the ranking, the generation node can be selected.

Specifically, the provision command identifies a specific selected area related to the offline location of the stake node, generates a list of representative nodes located within the specific selected area, and creates a voting environment including the list of representative nodes with the stake. It can be provided to the node.

Specifically, the selection command selects the generating node according to the priority of the number of votes of the representative node, and when selecting the next-ranking generating node, if the separation distance from at least one previously selected generating node is greater than the threshold distance, The representative node can be selected as the generation node.

Specifically, the selection command checks the difference in the number of votes with the representative node of the next ranking when the separation distance is less than the critical distance, and selects the corresponding representative node as a generating node only if the difference in the number of votes is more than the critical number of votes. It can be selected.

Specifically, in the selection command, if the difference in the number of votes is less than the threshold number of votes, at least one of the number of votes of the corresponding representative node and the difference in the number of votes with the representative node of the next ranking is recorded as the number of bonus votes, and a new vote is performed. Ensure that it is reflected as the actual number of votes in the environment.

Specifically, the critical number of votes is determined according to the number of generation nodes whose separation distance among the at least one previously selected generation node is less than the threshold distance, and the greater the number of generation nodes less than the threshold distance, the greater the number. It can be decided by the difference in votes.

A method of operating a blockchain operating device according to an embodiment of the present invention to achieve the above purpose is to select a generation node with the authority to create blocks among representative nodes for a stake node holding a stake in the blockchain network. A provision step of providing a voting environment for selection; and a selection step of selecting the generation node based on at least one of the number of votes received by the representative node in the voting environment and the location of the representative node.

Specifically, in the selection step, the offline area where all representative nodes are distributed in the blockchain network is divided into selection areas corresponding to the required number of generation nodes, and the number of votes of the representative node for each divided selection area is given priority. Depending on the ranking, the generation node can be selected.

Specifically, the provision step identifies a specific selected area related to the offline location of the stake node, generates a list of representative nodes located within the specific selected area, and establishes a voting environment including the list of representative nodes as the stake. It can be provided to the node.

Specifically, in the selection step, the generation node is selected according to the priority of the number of votes of the representative node, and when selecting the next-ranking generation node, if the separation distance from at least one previously selected generation node is more than the threshold distance, the The representative node can be selected as the creation node.

Specifically, in the selection step, when the separation distance is less than the threshold distance, the difference in the number of votes with the representative node of the next rank is checked, and only when the difference in the number of votes is more than the threshold number of votes is the representative node generated. It can be selected.

Accordingly, according to the blockchain operating device and its operating method according to an embodiment of the present invention, in a blockchain network environment where Delegated Proof of Stake (DPoS) is applied, blocks are generated considering the location of the node. By selecting generation nodes, which are nodes with authority, by distributing them regionally, it is possible to prevent problems of node contamination, such as data manipulation, that may occur when generation nodes are selected in a regionally concentrated manner.

Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings.

Figure 1 is a diagram illustrating a blockchain network system according to an embodiment of the present invention.

As shown in Figure 1, the blockchain network system according to an embodiment of the present invention includes a stake node 10, which is a node holding a stake in the blockchain network, and a creation node, which is a node with the authority to create blocks. It may have a configuration that includes a representative node (20), which is a node that participates as a candidate in the voting environment for selection of , and a blockchain operating device (30) that serves as a voting environment for selecting a generating node.

Here, in the case of each node in the blockchain network including the stake node 10, the representative node 20, and the blockchain operating device 30, for example, mobile terminals such as smartphones, computers such as PCs, and users It can be implemented in various forms, including a wired or wireless mobile or fixed controller with an interface, or a server.

For reference, if each node in the blockchain network is implemented in the form of a server, for example, it may be implemented in the form of a web server, database server, proxy server, etc., and the network load distribution mechanism or service device may be implemented on the Internet or other network. One or more of a variety of software that enables operation may be installed, thereby enabling it to be implemented as a computerized system.

In addition, the network may be an http network, a private line, an intranet, or any other network, and the connection between each component in the blockchain network system according to an embodiment of the present invention may have data It can be connected to a secure network to avoid attacks by hackers or other third parties.

Meanwhile, in this blockchain network, continuously increasing data is recorded in blocks of specific units, and each participant node that makes up the P2P (peer-to-peer) network can manage the blocks in a chain-type data structure. .

At this time, blockchain data composed of a chain-type data structure is operated in the form of a distributed ledger at each node without a central system.

Each node that makes up the blockchain network manages blocks in a chain based on a data structure that records the hash value of the previous block in the current block, allowing the previous block to be referenced through the hash value.

Therefore, as the number of blocks managed in a chain at each node accumulates, forgery and falsification of transaction data recorded in the block becomes more difficult, and the reliability of transaction data recorded in each block can be improved.

In particular, in the case of a blockchain network according to an embodiment of the present invention, the stake node 10 votes for the representative node that participated as a candidate in the selection of the generation node and receives compensation accordingly. of Stake) is adopted.

In this regard, in conventional blockchain networks, the method of distributing newly supplied digital claims, for example, cryptocurrency, is the Proof of Work or Proof of Stake method, which each depends on computer power or the size of the stake. Stake) was mainly applied.

However, by its nature, Proof of Work is winner-takes-all, and Proof of Stake provides the right to create blocks to a minority with a large amount of stake, that is, cryptocurrency, which is a reward for block creation. It has a structure where more is always distributed.

Therefore, there is a structural problem in that general individuals with a small stake or blockchain devices with low computing power are excluded from the distribution of newly supplied cryptocurrency, which is the compensation for creating a new blockchain. Additionally, this proof method quickly creates a new blockchain. There is also a structural problem in that it takes time to create and propagate it to the entire network.

Accordingly, in one embodiment of the present invention, in order to compensate for the above shortcomings of the Proof of Work and Proof of Stake methods, the stake node 10 is a representative node that participated as a candidate in selecting the generation node. The representative delegated share method (DPoS) is adopted by voting and receiving compensation accordingly.

In this delegated stake method (DPoS), the number of nodes that generate blocks is limited in advance and blocks are generated once in a randomly generated order, thereby shortening the time for the generated blocks to be recognized. there is.

However, in the case of Delegate Stake (DPoS), the number of nodes with the authority to create blocks is predetermined and the number is not large, so there is a possibility that nodes can be easily contaminated, such as data manipulation due to external hacking, etc., especially in blocks. If the nodes that generate are concentrated locally, the risk of such contamination can be seen as even greater.

Accordingly, in one embodiment of the present invention, in a blockchain network environment where Delegated Proof of Stake (DPoS) is applied, the generation nodes, which are nodes with the authority to create blocks, are distributed regionally in consideration of the location of the node. We would like to propose a method for selecting this, and the following will explain in more detail the configuration of the stake node 10 and the blockchain operating device 30 to realize this.

Figure 2 shows the configuration of a stake node 10 according to an embodiment of the present invention.

As shown in FIG. 2, the stake node 10 according to an embodiment of the present invention includes a connection unit 11 that connects to the voting environment provided by the blockchain operating device 30, and a voting operation within the voting environment. It may have a configuration including a processing unit 12 that processes.

All or at least part of the configuration of the stake node 10, including the above connection unit 11 and the processing unit 12, is implemented in the form of a software (application) module or hardware module executed by a processor, or is implemented in the form of a software module and It can also be implemented as a combination of hardware modules.

In particular, these configurations are for linking with the blockchain network, and may be the entity that maintains and manages blockchain data based on the blockchain algorithm, which may be in the form of a virtual machine or API (Application Programming Interface). It can be implemented as:

Meanwhile, the stake node 10 according to an embodiment of the present invention may have a configuration that further includes a communication unit 13, which is an RF module for actual communication with the blockchain operating device 30, etc., in addition to the configuration described above. .

For reference, since this configuration of the communication unit 13 corresponds to the communication unit 1310 to be described with reference to FIG. 3, a detailed description will be provided below.

In the end, the stake node 10 according to an embodiment of the present invention can select generation nodes, which are nodes with the authority to create blocks, by regionally distributing them in the blockchain network. Hereinafter, the stake node 10 for this purpose will be described. Each configuration will be described in more detail.

The connection unit 11 performs the function of accessing a voting environment for selecting a generation node.

More specifically, the connection unit 11 connects to the voting environment provided by the blockchain operating device 30 to select a generation node with the authority to create blocks.

Here, the voting environment provided by the blockchain operating device 30 can be provided by considering the cycle in which blocks are created in a blockchain network that adopts the Delegated Proof of Stake (DPoS) method.

In this voting environment, candidate information of the representative node 20 participating as a candidate, for example, computing power; Program operation policies or performance; The proportion of profits used for reinvestment and the purpose of the reinvestment; The excellence of DAPP in discovery, development, and support; and community information, etc., and may further include various qualitative and quantitative judgment criteria that are not limited thereto.

In particular, in one embodiment of the present invention, in order to select a regional division of generation nodes, the offline area where all representative nodes (20) are distributed in the blockchain network is selected corresponding to the required number of generation nodes (e.g., 21). It can be divided into areas.

In this case, the generation node may be selected according to the priority of the number of votes of the representative node 20 for each divided selection area.

To this end, the blockchain operating device 30 identifies a specific selected area related to the offline location of the stake node 10, generates a list of representative nodes 20 located within the identified specific selected area, and selects the corresponding representative node ( A voting environment including the list of 20) can be provided to the stake node (10).

Here, the specific selected area related to the offline location of the stake node 10 may be divided into regional divisions to which the offline location of the stake node 10 belongs, such as country, city, and other administrative districts.

Through this, the stake nodes (10) can be provided with an individual voting environment that includes only the list of representative nodes (20) who participated as candidates in the region to which they belong.

The processing unit 12 performs the function of processing the voting operation of the stake node 10.

More specifically, the processing unit 12 collects the voting results exercised by the stake node 10 with reference to the list of representative nodes 20 and each candidate information in the voting environment, and sends the collected information to the stake node 10. It is transmitted to the blockchain operating device 30 as voting execution information.

At this time, the processing unit 12 may peddle voting rights with one vote per cryptocurrency held by the processor, rather than peddling the voting rights of one vote per holder, which is granted to equity holders.

However, in this case, in order to minimize the concentration of voting rights caused by large capital, voting rights can be limited so that each holder is given a set number of voting rights (e.g. 30) and can exercise them to different representative nodes (20). .

Meanwhile, in relation to this, when voting execution information is received from a plurality of stake nodes 10, the blockchain operating device 30 collects them and selects a generation node.

At this time, the blockchain operating device 30 basically selects the generation node according to the priority of the number of votes of the representative node 20. In order to consider regional division of the generation node, when selecting the next-rank generation node, the previous The distance from at least one selected generation node may be additionally considered.

In other words, when selecting the next-ranking generation node, the blockchain operating device 30 checks the separation distance from at least one previously selected generation node, and selects the corresponding representative node as the next-ranking node only if the confirmed separation distance is greater than the critical distance. is selected as the generation node.

If the separation distance is less than the critical distance, check the difference in the number of votes with the representative node of the next rank, and if the difference in the number of votes is more than the critical number of votes, that is, if the number of votes is significantly different from the representative node of the next rank. Only then, the corresponding representative node can be selected as the next-rank generation node.

In this way, the reason for setting an exception in selecting a generating node in cases where the number of votes is significantly different from that of the next ranked representative node is that the representative node, which has superior qualitative and quantitative performance compared to other representative nodes, simply due to the location relationship. This is to minimize unfair rejection in the selection of generation nodes.

In addition, the critical number of votes, which is the basis for the difference in the number of votes from the representative node of the next ranking, may be determined according to the number of generation nodes whose separation distance is less than the critical distance among at least one previously selected generation node. This critical number of votes can be determined by the difference in the number of votes, which increases as the number of generating nodes is less than the critical distance.

In this way, it can be understood that the difference in votes is increased as the number of generation nodes that are less than the critical distance among at least one previously selected generation node increases, in order to prevent generation nodes from being selected concentrated in a specific area.

In other words, in areas where generation nodes are likely to be concentrated, the criteria for determining the location of generation nodes become more stringent, allowing generation nodes to be distributed over a wider area.

Meanwhile, when selecting the next-ranking generation node, the blockchain operating device 30 checks the separation distance from at least one previously selected generation node, and as a result, the separation distance is less than the critical distance, and the difference in votes from the next-ranking representative node If is less than the critical number of votes, the representative node is eliminated from selection as a generating node, but an advantage can be given to the representative node in a new voting environment.

In other words, if the difference in the number of votes with the representative node of the next ranking is less than the threshold number of votes and there is a representative node that was eliminated in the selection of the generating node, the blockchain operating device 30 determines the number of votes of the representative node and the next ranking. By recording at least one of the differences in the number of votes with the representative node as the number of bonus votes and reflecting it as the number of actual votes in the new voting environment, there is a possibility that the representative node that obtained the number of bonus votes in the new voting environment will be selected as the generating node. can increase.

It has been mentioned that each configuration within the stake node 10 described above may be implemented in the form of a software module or hardware module executed by a processor, or may also be implemented in the form of a combination of a software module and a hardware module.

In this way, a software module, a hardware module, or a combination of a software module and a hardware module executed by a processor may be implemented as an actual hardware system (eg, a computer system).

Therefore, hereinafter, a hardware system 1000 that implements the stake node 10 according to an embodiment of the present invention in hardware form will be described with reference to FIG. 3.

After completing the description of the configuration of the stake node 10 according to an embodiment of the present invention, we will continue with the description of the configuration of the blockchain operating device 30.

Figure 4 shows a schematic configuration of a blockchain operating device 30 according to an embodiment of the present invention.

As shown in FIG. 4, the blockchain operating device 30 according to an embodiment of the present invention includes a provision unit 31 that provides a voting environment for selecting a generation node, which is a node that generates blocks in a blockchain network. , and a selection unit 32 that collects the results of the voting event and selects the generation node.

In particular, these configurations are configurations that support linkage with the blockchain network, and may be the entity that maintains and manages blockchain data based on the blockchain algorithm, which may be a virtual machine or API (Application Programming Interface). It can be implemented in the form

Meanwhile, the blockchain operating device 30 according to an embodiment of the present invention, in addition to the above-described configuration, further includes a communication unit 33, which is an RF module for actual communication with the stake node 10 and the representative node 20. It can have a configuration that does.

For reference, since the configuration of the communication unit 35 corresponds to the communication unit 3310 to be described with reference to FIG. 5, specific details will be described below.

In the end, the blockchain operating device 30 according to an embodiment of the present invention can locally distribute and select generation nodes, which are nodes with the authority to create blocks in the blockchain network, through the above-described configuration, which will be described below. Each configuration within the blockchain operating device 30 to be realized will be described.

The provision unit 31 performs the function of providing a voting environment for selecting a generation node.

More specifically, the provision unit 31 provides a voting environment for selecting a creation node from the representative node for the stake node 10 holding a stake in the blockchain network.

At this time, the provider 31 provides a voting environment for the stake node 10 in consideration of the cycle in which blocks are created in a blockchain network that adopts the Delegated Proof of Stake (DPoS) method. can be decided.

In this voting environment, candidate information of the representative node 20 participating as a candidate, for example, computing power; Program operation policies or performance; The proportion of profits used for reinvestment and the purpose of the reinvestment; The excellence of DAPP in discovery, development, and support; and community information, etc., and may further include various qualitative and quantitative judgment criteria that are not limited thereto.

In particular, in one embodiment of the present invention, in order to select a regional division of generation nodes, the offline area where all representative nodes (20) are distributed in the blockchain network is selected corresponding to the required number of generation nodes (e.g., 21). It can be divided into areas.

In this case, the generation node may be selected according to the priority of the number of votes of the representative node 20 for each divided selection area.

To this end, the provision unit 31 identifies a specific selected area related to the offline location of the stake node 10, generates a list of representative nodes 20 located within the identified specific selected area, and selects the representative node 20. A voting environment including a list of can be provided to the stake node (10).

Here, the specific selected area related to the offline location of the stake node 10 may be divided into regional divisions to which the offline location of the stake node 10 belongs, such as country, city, and other administrative districts.

Through this, the provision unit 31 can provide an individual voting environment that includes only a list of representative nodes 20 who participated as candidates in the region where the offline location belongs to each stake node 10.

Meanwhile, stake nodes (10) exercise their voting rights through the voting environment provided to them, and instead of peddling the voting rights of 1 vote per holder, which is granted to stake holders, they peddle their voting rights with 1 vote for each cryptocurrency they own. can do.

However, in this case, in order to minimize concentration of voting rights by large capital, voting rights may be limited so that each holder is given a set number of voting rights (e.g. 30) and can exercise them to different representative nodes (20). .

The selection unit 32 collects voting results and performs the function of selecting a generation node.

More specifically, the selection unit 32 selects a generation node by collecting the voting results exercised by the stake node 10 with reference to the list of representative nodes 20 in the voting environment and each candidate information.

At this time, the selection unit 32 basically reflects the priority of the number of votes of the representative node 20 when selecting the generation node. In particular, when selecting the next-ranking generation node to take into account the regional division of the generation node, The distance from at least one previously selected generation node may be additionally considered.

That is, when selecting the next-rank generation node, the selection unit 32 checks the separation distance from at least one previously selected generation node, and selects the corresponding representative node as the next-rank generation node only if the confirmed separation distance is greater than the threshold distance. It can be selected as a node.

If the separation distance is less than the critical distance, check the difference in the number of votes with the representative node of the next rank. If the difference in the number of votes is more than the critical number of votes, in other words, there is a significant difference in the number of votes with the representative node of the next rank. Only in some cases, the representative node can be selected as the next generation node.

In this way, the reason for setting an exception in selecting a generating node in cases where the number of votes is significantly different from that of the next ranked representative node is that the representative node, which has superior qualitative and quantitative performance compared to other representative nodes, simply due to the location relationship. This is to minimize unfair rejection in the selection of generation nodes.

In addition, the critical number of votes, which is the basis for the difference in the number of votes from the representative node of the next ranking, may be determined according to the number of generation nodes whose separation distance is less than the critical distance among at least one previously selected generation node. This critical number of votes can be determined by the difference in the number of votes, which increases as the number of generation nodes less than the critical distance increases.

In this way, it can be understood that the difference in votes is increased as the number of generation nodes that are less than the critical distance among at least one previously selected generation node increases, in order to prevent generation nodes from being selected concentrated in a specific area.

In other words, the selection unit 32 can distribute the generation nodes over a wide area by making the location judgment criteria for the generation nodes more stringent in areas where generation nodes are likely to be concentrated.

Meanwhile, when selecting the next-ranking generation node, the selection unit 32 checks the separation distance from at least one previously selected generation node, and as a result, the separation distance is less than the critical distance, and the difference in votes from the next-ranking representative node is critical. If the number of votes is less than the number of votes, the representative node is eliminated from selection as a creation node, but an advantage can be given to the representative node in a new voting environment.

In other words, if the difference in the number of votes with the representative node of the next ranking is less than the threshold number of votes and there is a representative node that was eliminated in the selection of the generating node, the selection unit 32 selects the number of votes of the representative node and the representative of the next ranking. By recording at least one of the differences in the number of votes with the node as the number of bonus votes and reflecting it as the actual number of votes in the new voting environment, the representative node that obtained the number of bonus votes in the new voting environment increases the possibility of being selected as a generating node. It is possible.

Below, we will continue to explain the blockchain network system and the operational flow of each component within the system according to an embodiment of the present invention.

Figure 6 shows the operation flow in a blockchain network system according to an embodiment of the present invention.

First, the blockchain operating device 30 creates and provides a voting environment to select a creation node from the representative node according to the connection of the stake node 10 holding a stake in the blockchain network (S11-S13) )

At this time, the blockchain operating device 30 selects an offline area where all representative nodes (20) are distributed in the blockchain network to select a regional division of the generation nodes, corresponding to the required number of generation nodes (e.g., 21). It can be divided into selected areas.

In this case, the generation node may be selected according to the priority of the number of votes of the representative node 20 for each divided selection area.

To this end, the blockchain operating device 30 identifies a specific selected area related to the offline location of the stake node 10, generates a list of representative nodes 20 located within the identified specific selected area, and selects the corresponding representative node ( A voting environment including the list of 20) can be provided to the stake node (10).

Subsequently, the stake node (10) collects the results of the votes cast by the stake node (10) with reference to the list of representative nodes (20) and each candidate information in the voting environment, and uses the collected information to vote for the stake node (10). As execution information, the blockchain operating device 30 is used (S14-S15).

At this time, the stake node (10) can peddle voting rights with one vote per cryptocurrency it owns, rather than peddling the voting rights of one vote per holder, which is granted to stake holders.

However, in this case, in order to minimize the concentration of voting rights caused by large capital, voting rights can be limited so that each holder is given a set number of voting rights (e.g. 30) and can exercise them to different representative nodes (20). .

Afterwards, when voting execution information is received from a plurality of stake nodes 10, the blockchain operating device 30 collects them and selects a generation node (S16-S18).

At this time, the blockchain operating device 30 basically selects the generation node according to the priority of the number of votes of the representative node 20. In order to consider regional division of the generation node, when selecting the next-rank generation node, the previous The distance from at least one selected generation node may be additionally considered.

In other words, when selecting the next-ranking generation node, the blockchain operating device 30 checks the separation distance from at least one previously selected generation node, and selects the corresponding representative node as the next-ranking node only if the confirmed separation distance is greater than the critical distance. is selected as the generation node.

If the separation distance is less than the critical distance, check the difference in the number of votes with the representative node of the next rank, and if the difference in the number of votes is more than the critical number of votes, that is, if the number of votes is significantly different from the representative node of the next rank. Only then, the corresponding representative node can be selected as the next-rank generation node.

After completing the description of the operation flow in the blockchain network system according to an embodiment of the present invention, we will continue with the description of the operation flow in the stake node 10.

Figure 7 shows the operation flow in the stake node 10 according to an embodiment of the present invention.

First, the connection unit 11 connects to the voting environment provided by the blockchain operating device 30 to select a generation node with the authority to create blocks (S21-S22).

Here, the voting environment provided by the blockchain operating device 30 can be provided by considering the cycle in which blocks are created in a blockchain network that adopts the Delegated Proof of Stake (DPoS) method.

In particular, in one embodiment of the present invention, in order to select a regional division of generation nodes, the offline area where all representative nodes (20) are distributed in the blockchain network is selected corresponding to the required number of generation nodes (e.g., 21). It can be divided into areas.

In this case, the generation node may be selected according to the priority of the number of votes of the representative node 20 for each divided selection area.

To this end, the blockchain operating device 30 identifies a specific selected area related to the offline location of the stake node 10, generates a list of representative nodes 20 located within the identified specific selected area, and selects the corresponding representative node ( A voting environment including the list of 20) can be provided to the stake node (10).

Here, the specific selected area related to the offline location of the stake node 10 may be divided into regional divisions to which the offline location of the stake node 10 belongs, such as country, city, and other administrative districts.

Through this, the stake nodes (10) can be provided with an individual voting environment that includes only the list of representative nodes (20) who participated as candidates in the region to which they belong.

Furthermore, the processing unit 12 collects the voting results exercised by the stake node 10 with reference to the list of representative nodes 20 and each candidate information in the voting environment, and uses the collected information to execute the vote of the stake node 10. It is transmitted as information to the blockchain operating device 30 (S23-S25).

At this time, the processing unit 12 may peddle voting rights with one vote per cryptocurrency held by the processor, rather than peddling the voting rights of one vote per holder, which is granted to equity holders.

However, in this case, in order to minimize the concentration of voting rights caused by large capital, voting rights can be limited so that each holder is given a set number of voting rights (e.g. 30) and can exercise them to different representative nodes (20). .

Meanwhile, in relation to this, when voting execution information is received from a plurality of stake nodes 10, the blockchain operating device 30 collects them and selects a generation node.

At this time, the blockchain operating device 30 basically selects the generation node according to the priority of the number of votes of the representative node 20. In order to consider regional division of the generation node, when selecting the next-rank generation node, the previous The distance from at least one selected generation node may be additionally considered.

In other words, when selecting the next-ranking generation node, the blockchain operating device 30 checks the separation distance from at least one previously selected generation node, and selects the corresponding representative node as the next-ranking node only if the confirmed separation distance is greater than the critical distance. is selected as the generation node.

If the separation distance is less than the critical distance, check the difference in the number of votes with the representative node of the next ranking, and if the difference in the number of votes is more than the critical number of votes, that is, if the number of votes is significantly different from the representative node of the next ranking. Only then, the corresponding representative node can be selected as the next-ranking generation node.

After completing the description of the operation flow in the stake node 10 according to an embodiment of the present invention, we will continue with the description of the operation flow in the blockchain operating device 30.

Figure 8 shows the operation flow in the blockchain operating device 30 according to an embodiment of the present invention.

First, the provision unit 31 creates and provides a voting environment for selecting a generation node from the representative node according to the connection of the stake node 10 holding a stake in the blockchain network (S31-S33).

At this time, the provider 31 selects an offline area where all representative nodes 20 are distributed in the blockchain network to select a regional division of the generation nodes, and a selection area corresponding to the required number of generation nodes (e.g., 21). can be divided into

In this case, the generation node may be selected according to the priority of the number of votes of the representative node 20 for each divided selection area.

To this end, the provision unit 31 identifies a specific selected area related to the offline location of the stake node 10, generates a list of representative nodes 20 located within the identified specific selected area, and selects the representative node 20. A voting environment including a list of can be provided to the stake node (10).

Here, the specific selected area related to the offline location of the stake node 10 may be divided into regional divisions to which the offline location of the stake node 10 belongs, such as country, city, and other administrative districts.

Through this, the provision unit 31 can provide an individual voting environment that includes only a list of representative nodes 20 who participated as candidates in the region where the offline location belongs to each stake node 10.

Furthermore, the selection unit 32 receives the voting results exercised by the stake node 10 as voting execution information with reference to the list of representative nodes 20 and each candidate information in the voting environment, and selects the generation node based on this. (S34).

At this time, the selection unit 32 basically reflects the priority of the number of votes of the representative node 20 when selecting the generation node. In particular, when selecting the next-ranking generation node to take into account the regional division of the generation node, The distance from at least one previously selected generation node can be additionally considered (S35-S38).

That is, when selecting the next-rank generation node, the selection unit 32 checks the separation distance from at least one previously selected generation node, and selects the corresponding representative node as the next-rank generation node only if the confirmed separation distance is greater than the threshold distance. It can be selected as a node.

If the separation distance is less than the critical distance in step S37, check the difference in the number of votes with the representative node of the next ranking, and if the difference in the number of votes is more than the critical number of votes, in other words, the number of votes with the representative node of the next ranking is significant. Only in cases where there is a significant difference, the corresponding representative node can be selected as the next-ranking generation node (S38-S39).

Meanwhile, when selecting the next-ranking generation node, the selection unit 32 checks the separation distance from at least one previously selected generation node in step S37, and as a result, the separation distance is less than the critical distance, and selects the next-ranking representative node and the next-ranking representative node in step S39. If the difference in the number of votes is less than the critical number of votes, the representative node is eliminated from selection as a generating node, but an advantage can be given to the representative node in a new voting environment (S40).

In other words, if the difference in the number of votes with the representative node of the next ranking is less than the threshold number of votes and there is a representative node that was eliminated in the selection of the generating node, the selection unit 32 selects the number of votes of the representative node and the representative of the next ranking. By recording at least one of the differences in the number of votes with the node as the number of bonus votes and reflecting it as the actual number of votes in the new voting environment, the representative node that obtained the number of bonus votes in the new voting environment increases the possibility of being selected as a generating node. It is possible.

As discussed above, according to the operation method of each component in the blockchain network system according to an embodiment of the present invention, in a blockchain network environment where Delegated Proof of Stake (DPoS) is applied, the node's By considering location and selecting generation nodes, which are nodes with the authority to create blocks, by distributing them regionally, problems of node contamination such as data manipulation that may occur when generation nodes are selected in a regionally concentrated manner can be prevented in advance. there is.
