Description

Blockchain-based corporate investment system and control method

The present invention relates to a method for controlling a blockchain-based enterprise investment system and a blockchain-based enterprise investment system.

Blockchain is a technology that maintains security and integrity in a decentralized network environment without a centralized server or organization.

Blockchain is replicated and stored in the same way across multiple nodes, and the block contains the information about the transaction or transaction history of 'who delivered what to whom and when'. Blockchain is a huge decentralized ledger or ledger that contains information about all transaction details.

Since Bitcoin based on blockchain in 2009 was unveiled by Satoshi Nakamot, Blockchain has not only cryptocurrency systems such as Bitcoin and Ethereum, but also a platform providing service for smart contracts and cloud storage. It is applied in various fields such as services and blockchain computing services.

In particular, Ethereum is a platform announced by Vitali Buterin in 2014. It uses a Java-based turing-comlpete programming language called Solidity. Anyone can write smart contracts and distributed applications using the language, and create arbitrary rules for ownership, transaction formats, and state transition functions.

Unlike smart contracts, smart contracts are already coded in executable code, which is a computer language. Therefore, when a certain contract condition is achieved in smart contracts, specific execution codes are forcibly executed (contract fulfillment).

Meanwhile, start-ups or small- and medium-sized companies start or expand their business by receiving funds from outside.

Typically, venture capital (VC), government agencies, etc. can provide funds to the investee, but from the investor's point of view, the investment decision must be made with limited information about the investee and the risk of the contract failure of the investee is inevitable. I have no choice but to embrace.

Investors can also secure their funds through a crowdfunding investment model, which receives their investments from an anonymous majority by publishing their business projects on the Internet. It is difficult to verify the investment and if the profits of the project results are lower than expected, it is difficult to recover the investment.

Therefore, there is a need for research on technologies that can help win-win by providing a fair and safe investment platform or investment system for both investors and companies, while improving the limitations of the existing investment model.

The following patent documents have been published in relation to the technical field of the present invention.

Hereinafter, the present invention will be described in more detail according to the accompanying drawings.

Stakeholders related to the blockchain-based enterprise investment system include an investor 11, an invested company 12, a blockchain 13, and a smart contract 14.

The investor 11 is an individual or a company that holds a coin issued in the corporate investment system, and refers to a person who has funded the invested company 12 with the held coin.

However, the funding of the investor 11 to the invested company 12 is not a direct investment method, but is made by an indirect investment method through the blockchain 13 and the smart contract 14.

The invested company 12 refers to a company selected by the corporate investment system from among all types of candidate invested companies that require investment.

For example, the candidate invested company may be any start-up or small to medium-sized company, and the invested company 12 may be screened and selected according to a plurality of selection criteria.

The invested company 12 manages the business project and generates profit by operating the funds secured through the funding of the investor 11.

In addition, the investee 12 compensates for the funding (for example, dividend payment) to the investor 11 when the investment contract ends, and the compensation process is also performed through the blockchain 13 and the smart contract 14 .

Blockchain 13 refers to the main network operated through coins issued by the corporate investment system.

Blockchain 13 is replicated and distributed equally across multiple nodes, and blocks contain information about transactions or transaction details.

Each node stores and manages the same transaction book, and verifies the validity or authenticity of the newly created transaction based on the transaction book.

According to the above verification result, each transaction under certain conditions agreed to have been verified between nodes is stored as a block, and the block is propagated to each node and connected in the form added after the previous block. The blockchain stored in each node is updated.

Blockchain 13 is a hash value, not only is the front and back blocks connected to each other, but only the transactions agreed between the nodes are stored in the block, so it is technically impossible to falsify or store the information stored in the block for malicious purposes. .

The smart contract 14 is registered in the blockchain 13, and through the smart contract 14, the execution conditions for the investment contract of the investor 11 to the invested company 12 are confirmed, and the investment contract The process of verifying the investment contracts and implementing them is automated on the network.

The investor 11 and the investee 12 can confirm and confirm the information recorded in the smart contract 14 in real time.

Shown in FIG. 2 is an independent blockchain platform named "Dsion", which is specialized in a blockchain platform and a decentralized blockchain platform as a communication space for corporate investment. "To provide modules (eg classes and libraries) as open source to stakeholders.

The blockchain-based enterprise investment system proposed in the present invention is not particularly limited to the configuration of FIG. 2, roles of each configuration, and application algorithm, and may be configured differently from that shown in FIG. 2.

Referring to FIG. 2, the blockchain-based enterprise investment system is constructed on the Dion network.

The coin holder 20 means a person who holds coins issued in the above corporate investment system, and the symbol of the coin may be, for example, "DSN". The ether ratio may be 1 ETH = 3,000 DSN.

The coin holder 20 may be a master node 21, a sub node 22, or an investor 23.

The master node 21 is in charge of block creation in the Dion network, and is delegated voting rights from the coin holder 20 to make decisions on the agenda.

In addition, the master node 21 processes each transaction occurring in the process performed by the above enterprise investment system, and each transaction is collected from the sub-node 22 and transmitted to the master node 21.

As such, as the master node 21 is dedicated to block generation and transaction processing, it improves the speed and processing efficiency of the consensus process.

In addition, the master node 21 may perform a first vote to determine whether or not to perform the funding process for the invested company 25 and determine the investment conditions including the investment method for the invested company 25 In order to do so, a second vote can be conducted.

The funding process is a process performed to conclude and manage the investment contract of the investor 23 with respect to the invested company 25.

In addition, the master node 21 may be selected from the sub-nodes 22, for example, a total of 21 nodes.

Whenever a block is generated by the master node 21, 4.7 DSN is issued, and the block is generated every 3 seconds.

The master node 21 receives a certain percentage of coins issued as a reward for role performance whenever each block of the block chain 26 is generated, and can receive coins at a reward rate of 40% per block.

In the above corporate investment system, the Delegated Proof Of Stake (DPOS) method, which is distinguished from Proof Of Work (POW) or Proof Of Stake (POS), is applied in relation to the master node 21 and the blockchain 26.

The DPOS method is a delegated proof-of-stake method that delegates authority to the upper node (witness) determined as a result of voting by nodes constituting the network to agree. The advantage of reducing the consensus time and cost is the small number of parent nodes, but since authority is concentrated on a small number of people, the reliability of the parent node is very important and there are security issues for the parent node.

The above corporate investment system can be operated according to a preset consensus algorithm "Practical Byzantine Fault Tolerance".

The PBFT algorithm is a consensus algorithm developed so that all nodes participating in the distributed system can successfully agree when the distributed system is an asynchronous system where there can be Byzantine nodes (traitor nodes) that do not perform the promised action.

The PBFT algorithm solves the problem that the existing BFT algorithm was able to agree only in a synchronous system, so that the asynchronous system with a Byzantine node can be agreed through two broadcast processes.

The detailed operation method of the PBFT algorithm is disclosed on the web page below.

https://www.usenix.org/legacy/events/osdi99/full_papers/castro/castro_html/castro.html

The sub-node 22 supports the role of the master node 21, and selects and selects the invested company 25 through verification and evaluation among the candidate invested companies 24.

That is, the sub-node 22 can vote to select the investee 25 from the candidate investee 24.

In addition, the sub-node 22 collects each transaction generated in the process performed by the above enterprise investment system and transmits it to the master node 21. The role of the master node 21 is transaction processing, and the role of the subnode 22 is divided into transaction collection.

In addition, the sub-node 22 provides RAM, a network, a CPU, and the like corresponding to the resources of DApp, which is a decentralized application of Dcyon.

In addition, the sub-node 22 may be promoted to the master node 21 through voting in the absence of the master node 21, for example, a total of 75 nodes.

The subnode 22 receives a certain percentage of coins issued as a reward for role performance whenever each block of the blockchain 26 is created, and can receive coins at a reward rate of 40% per block.

These master nodes 21 and sub-nodes 22 are required to operate the server of the recommended specifications required by the above enterprise investment system, and have a certain amount of coins (for example, 0.2% DSN) issued.

Here, the server may be implemented by at least one or more computing devices in various forms. For example, a smart phone, a laptop computer, a personal digital assistants (PDA), a portable multimedia player (PMP), It may be a navigation computer, a slate PC, a tablet PC, or a desktop computer.

Investor 23 means a user who locks and registers more than a certain amount of coins for investment or voting rights in the above corporate investment system. That is, the investor 23 is a user registered in advance in the above enterprise investment system.

The investor 23 has the right to vote for the master node 21 and the subnode 22, and can participate in investment in the invested company 25.

The investor 23 can be the subnode 22.

The candidate invested company 24 may be a company selected through competition or directly applying to the above-mentioned enterprise investment system.

The candidate investees 24 are evaluated by the subnode 22 based on the scoring and milestone of the support system.

Here, scoring means the result of voting for the candidate invested company 24 so that the sub-node 22 can verify the appropriateness of investment through the company evaluation, and the result is recorded in the blockchain 26.

In addition, the milestone means the business plan and progress schedule submitted by the candidate invested company 24, and the contents are also recorded on the blockchain 26.

The invested company 25 is selected by the sub-node 22 among the candidate invested companies 24, and if the investment decision is made by the master node 23, the divided investment may proceed twice in accordance with the progress of the milestone .

The invested company 25 should record the usage history of the investment money on the blockchain 26 through D-Sion's D-App.

The investor 23 may monitor the investment management status of the invested company 25 recorded in the blockchain 26 after the investment proceeds through the fund management system of the support system.

For example, the investor 23 is in the first round of funding for start-up A company, and after the first round of funding is completed for start-up B company, the second round of funding has been suspended for some reason, and start-up C company You can check at any time that the 1st and 2nd funding has been completed.

Blockchain 26 verifies, records or stores each transaction issued in the process performed by the above enterprise investment system.

Blockchain 26 stores smart contracts created in the funding process.

At this time, the smart contract is operated through D-Sion's D-App, and the smart contract records the investment terms for the invested company 25 and the investment contract of the investor 23 for the invested company 25. .

The above enterprise investment system includes fund storage that operates and manages funds to maintain the platform, and the fund storage is divided into three types according to the purpose.

The investment fund storage 27 accumulates coins at a reward rate of 15% per block each time a block is created.

Coins accumulated in the investment fund storage 27 are used as a basic fund for the master node 21 to start investing in the invested company 25.

The value guarantee fund storage 28 receives and stores a certain percentage of coins that are issued each time each block of the blockchain 26 is created, and earns coins (coins for value guarantee) at a compensation rate of 5% per block. can do.

Coins accumulated in the value guarantee fund storage 28 are used to preserve a portion of the invested amount of the investor 23 when it is difficult for the investor 23 to recover the investment principal from the invested company 25.

The value guarantee fund storage 28 according to some embodiments accumulates a coin for value guarantee in the above funding process, and the coin for value guarantee is a value guarantee process performed when the investment contract of the investor 23 ends after the funding process Is determined based on the value guarantee token of the investor (23).

In addition, the Value Assurance Token (VAT) is issued based on the coin for funding as a transaction occurs in which the investor 23 sends a coin for funding to the invested company 25 selected in the above corporate investment system. It is transmitted to the investor 23.

That is, the value guarantee token is a token that is defined by the above corporate investment system and is issued to guarantee some of the total value of the coin for funding while the investment contract of the investor 23 remains in effect.

Specifically, the value guaranteed by the value guarantee token according to an embodiment is based on the approval rate of the first voting performed by the plurality of master nodes 21 to determine whether to perform the funding process for the invested company 25 Can be set to

In addition, the value guaranteed by the value guarantee token according to another embodiment may be set on the basis of the approval rate of the first vote and the “investment” method of the investor 23.

For example, the criteria for the value guaranteed by the value guarantee token can be defined as shown in the table below.

투자 방식Investment method	배당 방식Dividend method	수익분배 방식Revenue distribution method
산정 기준Calculation criteria	제 1 투표의 찬성률1st vote	제 1 투표의 찬성률의 30%30% of the 1st vote
산정 공식Calculation formula	VAT 보증비율 = 찬성률VAT guarantee ratio = approval rate	VAT 보증비율 = 찬성률 * 0.3VAT Guarantee Rate = Pros rate * 0.3
펀딩용 코인에 대한 보증 비율Percentage of guarantee on coin for funding	50~80%50 ~ 80%	15~30%15 ~ 30%

If the approval rate of the first vote above is more than 80%, the guarantee rate for the coin for funding does not exceed 80%.

The value guarantee token is issued according to the request for issuance of the invested company 25, and information on the value guarantee token may be recorded in the smart contract corresponding to the investment contract of the investor 23.

At this time, the invested company (25) is required to issue a request to issue a value guarantee token and issuance request is possible, and the master node (21) can perform a third vote to determine whether to grant the issue request authority. have.

In addition, the value guarantee fund storage 28 according to some embodiments transmits a value guarantee coin to the investor 23 in the value guarantee process performed when the investment contract of the investor 23 ends after the funding process.

At this time, the coin for value guarantee can be determined by subtracting the coin received from the invested company 25 from the coin corresponding to the value guaranteed by the value guarantee token.

The reverse fund storage 29 accumulates 1% of the compensation amount when the investee 25 provides compensation for the funding to the investor 23.

Coins accumulated in the reverse fund storage 29 may be accumulated in the investment fund storage 27 by the vote of the master node 21 or incinerated to maintain the proper value of the coin and prevent inflation.

Referring to Figure 2, the overall operation of the configuration of the above enterprise investment system is as follows.

The plurality of master nodes 21 respectively verify the validity or authenticity of the newly generated transaction in the Dion network, and agree on the verification result according to the PBFT algorithm.

Each transaction within a certain time (for example, 3 seconds) agreed to have been verified between the master nodes 21 is stored as a block, and the newly created block is added after the block in front of the blockchain 26 It is connected to (S110).

Each time a block is created by the master node 21, a coin (for example, 4.7 DSN) is issued, and the investment fund storage 27 accumulates a part (for example, 15%) of the issued coin (S120) ).

The plurality of sub-nodes 22 verify and evaluate the candidate investee 24 using the support system (S210).

The plurality of sub-nodes 22 votes to select an invested company 25 from among the verified candidate invested companies 24, and list up the selected invested companies 25 (S220).

The plurality of master nodes 21 votes to determine whether to perform a funding process for each of the listed companies to be invested 25.

The plurality of master nodes 21 respectively decide to perform a funding process for the invested company 25 according to the vote (S230).

The investor 23 directly selects the invested company 25 in which the funding process is in progress, enters into an investment contract, and proceeds to invest in the invested company 25 using the held coins (S240).

The master node 21 also directly selects the invested company 25 in which the funding process is in progress, enters into an investment contract, and uses the coins accumulated in the investment fund storage 27 to invest in the invested company 25. (S240).

When the investment contract is terminated, the investee 25 pays the investment 23 to the investor 23 according to the investment contract, and the compensation is determined differently depending on whether the investor's investment method is a dividend method or a profit distribution method (S250). .

Hereinafter, a method of controlling a blockchain-based enterprise investment system according to some embodiments will be described in detail for each individual process.

The enterprise investment system performs a funding process, and each transaction generated in the funding process is stored in the blockchain 33 of the enterprise investment system.

At this time, the funding process is a process performed to conclude and manage the investment contracts of the investors 32 registered in advance in the enterprise investment system.

The invested company 31 makes a request for generating a contract and issuing a value guarantee token with the corporate investment system (S310).

The enterprise investment system generates a smart contract 34 for investment in the invested company 31 selected in the enterprise investment system, and issues a value guarantee token (S320).

In the smart contract 34, the investment conditions for the invested company 31 are recorded.

In step S310, a request to generate a contract and a request to issue a value guarantee token are not necessarily made together.

In addition, a request to generate a contract is not necessarily required in step S310, and when the investee 31 requests for a value guarantee token, the enterprise investment system may perform step S320 correspondingly.

The enterprise investment system stores the smart contract 34 generated in step S320 in a block and records it in the blockchain 33 (S330).

The investor 32 directly selects an investment target and transmits a coin for funding to the invested company 31 (S340).

The enterprise investment system concludes an investment contract between the invested company 31 and the investor 32 through the smart contract 34 (S350).

Information on the investment contract of the investor 32 for the invested company 31 is recorded in the smart contract 34, and the corporate investment system stores it in a block and records it in the blockchain 33 (S360).

As the corporate investment system receives the coin for funding from the investor 32, it transmits the value guarantee token calculated based on the coin for funding to the investor 32 (S370).

At this time, the value guarantee token is a token that is defined by the enterprise investment system and is issued to guarantee some value among the total value of the coin for funding while the investment contract of the investor 32 is valid.

The value guarantee token is also recorded in the smart contract 34 as information on the investment contract.

The value guaranteed by the value guarantee token according to an embodiment may be set based on the approval rate of voting between a plurality of nodes constituting the corporate investment system to determine whether to perform the funding process for the invested company 31 You can.

The value guaranteed by the value guarantee token according to another embodiment may be set differently according to whether the “investment” method of the investor 32 is a dividend method or a profit distribution method. The investment method can also be determined by voting between multiple nodes constituting the corporate investment system.

In addition, as the corporate investment system receives the coin for funding from the investor 32, it transmits the coin for funding to the invested company 31 (S380).

The corporate investment system further performs a fund termination process after performing the funding process, and each transaction generated in the fund termination process is stored in the blockchain 43 of the corporate investment system.

At this time, the fund termination process is a process performed when an investor 42 requests to terminate the funding is received before the investment contract of the investor 42 registered in advance in the corporate investment system is terminated.

Investor 42 requests to cancel funding with the corporate investment system (S410).

The enterprise investment system confirms the investment contract of the investor 42 in the smart contract 44 recorded in the blockchain 43 (S420), and transmits a confirmation message for the request to terminate the funding to the investor 42 ( S430).

The investor 42 transmits the value guarantee token issued in the funding process to the corporate investment system (S440).

The enterprise investment system sends a confirmation message for the request to terminate funding to the investee 41, and the investee 41 transmits a coin for termination, which is determined differently according to the value guaranteed by the value guarantee token, to the enterprise investment system ( Not shown).

After receiving the value guarantee token and the coin for termination, the enterprise investment system terminates the investment contract between the invested company 41 and the investor 42 through the smart contract 34 (S450).

The corporate investment system incinerates the value guarantee token and records the information (including the incineration of the value guarantee token) on the termination of the investment contract in the smart contract 44.

The enterprise investment system stores this in a block and records it in the blockchain 43 (S460).

The enterprise investment system receives the value guarantee token and the coin for termination, and then transmits the coin for termination to the investor 42 (S470) and transmits the termination result to the invested company 41 (S480).

The enterprise investment system further performs a compensation process after performing the funding process, and each transaction generated in the compensation process is stored in the blockchain 53 of the enterprise investment system.

At this time, the compensation process is a process performed when receiving more coins than the coin for funding from the invested company 51 at the time when the investment contract of the investor 52 registered in advance in the enterprise investment system ends.

That is, the compensation process is a process related to the case where the investee 51 has earned more profits than the investor 52's investment.

The invested company 51 transmits a reward coin (more than the investor's investment amount) to the corporate investment system (S510).

The corporate investment system receives the coin for compensation, stores it in a block, and records it in the blockchain 53 (S520).

The investor 52 transmits the value guarantee token issued in the funding process to the corporate investment system (S530).

The enterprise investment system checks the investment contract of the investor 52 in the smart contract 54 recorded in the blockchain 53 (S540).

The corporate investment system incinerates the value guarantee token and records the information (including the incineration of the value guarantee token) on the termination of the investment contract in the smart contract 54.

The enterprise investment system stores this in a block and records it in the blockchain 53 (S550).

After receiving the value guarantee token and the reward coin, the enterprise investment system transmits the reward coin to the investor 52 (S560) and transmits the reward result to the invested company 51 (S570).

The reward coin transmitted in step S560 is determined differently depending on whether the investment 52 method of the investor 52 is a dividend method or a profit distribution method.

The enterprise investment system further performs a funding extension process after performing the funding process, and each transaction generated in the funding extension process is stored in the blockchain 63 of the company investment system.

At this time, the funding extension process is when an investor 62's investment contract is received at the time when the investment contract of the investor 62 ends when the investment contract of the investor 62 previously registered in the corporate investment system is possible. It is a process that is performed.

The investor 62 requests to extend the investment contract to the corporate investment system (S610).

The enterprise investment system confirms the investment contract of the investor 62 in the smart contract 64 recorded in the blockchain 63 (S620), and transmits a confirmation message to the investor 62 about the request to extend the investment contract (S630).

That is, whether or not the extension to the investment contract is possible is described in the smart contract 64, and the subsequent procedure can be performed only when the extension is possible.

The invested company 61 transmits a reward coin (more than the investor's investment amount) to the corporate investment system (S640).

The corporate investment system receives the coin for compensation, stores it in a block, and records it in the blockchain 63 (S650).

The enterprise investment system receives an extension request for the investment contract and a coin for compensation, and then concludes an investment contract (extension) between the invested company 61 and the investor 62 through the smart contract 64 (S660) ).

Information on the investment contract (extension) of the investor 62 for the invested company 61 is recorded in the smart contract 64, and the corporate investment system stores it in the block and records it in the blockchain 63 ( S670).

The corporate investment system subtracts the funding coin from the reward coin from the investor 62 and transmits the remaining coins to the investor 62 (S680).

At this time, the reward coin is determined differently according to whether the investor 62's investment method is a dividend method or a profit distribution method.

The corporate investment system transmits the funding coin and reward results to the invested company 61 (S690).

In the case of the funding extension process, there is no need to reissue the value guarantee token.

The enterprise investment system further performs a value assurance process after performing the funding process, and each transaction generated in the value assurance process is stored in the blockchain 73 of the enterprise investment system.

At this time, the value guarantee process is performed when a coin less than the coin corresponding to the value guaranteed by the value guarantee token is received from the invested company 71 when the investment contract of the investor 72 registered in advance in the enterprise investment system is terminated. It is a process.

The plurality of nodes constituting the enterprise investment system creates blocks of the blockchain 73.

The enterprise investment system issues a coin whenever each block of the blockchain 73 is generated, and transmits a certain percentage (n%) of the issued coin to the value guarantee fund storage 75 (S710).

The value guarantee fund storage 75 accumulates and manages the received value guarantee coin (S720).

The invested company 71 transmits a reward coin (less than the coin corresponding to the value guaranteed by the value guarantee token) to the corporate investment system (S730).

In step S730, when the reward coin that is less than the value guaranteed by the value guarantee token is received, the enterprise investment system requests the value guarantee coin to the value guarantee fund storage 75 (not shown).

At this time, the coin for value guarantee is determined by subtracting the coin received in step S730 from the coin corresponding to the value guaranteed by the value guarantee token.

The value guarantee fund storage 75 transmits the coin for value guarantee to the enterprise investment system (S740), and the enterprise investment system stores it in a block and records it in the blockchain 73 (S750).

The investor 72 transmits the value guarantee token issued in the funding process to the corporate investment system (S760).

The enterprise investment system checks the investment contract of the investor 72 in the smart contract 74 recorded in the blockchain 73 (S770).

The enterprise investment system incinerates the value guarantee token and records the information (including the incineration of the value guarantee token) on the termination of the investment contract in the smart contract 74.

The enterprise investment system stores this in a block and records it in the blockchain 73 (S780).

The corporate investment system transmits the reward coin and the value guarantee coin to the investor 72 (S790) and transmits the result to the invested company 71.
