Description

System Providing Mergers and Acquisitions Service based on Block Chain using multi-chain layer and Method for operating the same}

The embodiments disclosed in this document relate to a blockchain-based M&A service providing system and an operation method thereof that can implement a traditional M&A process based on a blockchain.

M&A (Mergers and Acquisitions) is a key tool for sustainable growth of companies in recent years, and is a financial tool that integrates companies through various transactions such as tender offer, asset purchase, and management acquisition. This M&A process is usually carried out by a special type of financial institution called an investment bank, which has the expertise to conduct transactions. The process involved in various M&A transactions is very complex, requiring a team of experts who can successfully complete the transaction.

The M&A process largely includes numerous steps such as marketing, preliminary due diligence, bidding, prior negotiator selection/confirmation due diligence, precise due diligence, price/transaction adjustment, stock transfer agreement, and so on. However, in the M&A process, no matter how thorough the contract is, it is difficult to cover all the contents in the contract.

In particular, it is not easy to evaluate a company's tangible and intangible assets fairly and accurately, so M&A negotiations are often broken at the stage where the terms of the transaction are discussed.

In addition, the current M&A process also poses a problem with the leakage of personal information. In principle, when providing information on the internal personnel and customers of the company to be acquired to the acquisition applicant, prior consent must be obtained from the party of personal information, but the information is provided to the acquisition applicant without prior consent for the purpose of due diligence for the merger. It is the reality that things are being done as custom.

An object of the present invention is to provide a block chain-based M&A service providing system and an operation method thereof capable of supplementing the disadvantages of the conventional M&A process.

1 is a diagram schematically illustrating a system for providing a Mergers and Acquisitions (M&A) service according to an embodiment of the present invention.

Referring to FIG. 1, the M&A service providing system 10 is a blockchain-based M&A service that can implement an M&A process that has been performed only offline (on-site) on an on-chain basis through blockchain technology. It is a delivery system.

Blockchain can function as a public transaction ledger, and it can mean a technology to prevent hacking that may occur during transactions such as virtual currency. In the case of existing financial companies, transaction records are kept on a centralized server, but the blockchain can distribute and record transaction details on the computers of all users participating in the transaction. Accordingly, the Bank of Korea defines blockchain as a decentralized public ledger management technology that jointly records and stores information and values produced by network participants. Blockchain's decentralized technology can be used to prevent data forgery by collating the transaction details recorded on multiple computers for each virtual currency transaction. In other words, since all participants share the ledger, the integrity of transaction details can be guaranteed. In addition, the blockchain provides a time stamp record to prevent double spending and modification of previous transaction records, and does not require an authorized third party, thus reducing costs required for maintenance, security, and financial transactions. can do.

Along with the blockchain, blockchain-based cryptocurrencies, bitcoin and ethereum, are attracting attention. Bitcoin refers to a cryptocurrency that can store and maintain transaction records by blockchain technology, and Ethereum refers to a cryptocurrency that can record additional information such as contracts as well as transaction technology. In particular, Ethereum is attracting more attention in that it can support smart contracts because it can record additional information.

Smart contract refers to a program code that can execute and execute contracts or negotiations using blockchain technology. Thus, the entire process can be automated by program code to supplement or replace legal contracts.

The cryptocurrency storage function of the existing Blockchain 1.0 can be programmed in various forms. Ethereum is a blockchain system that can execute smart contracts, and it can provide a global platform through EVM (Ethereum Virtual Machine). Developers can execute smart contracts through programming and manage digital assets such as virtual currency.

Nick Szabo, the first creator of smart contracts, defined smart contracts as a highly developed automatic contract execution method between machines in an unreliable computer networking environment, and various decentralized applications such as real estate contracts, online voting and healthcare on the blockchain. The platform has been extended so that it can be developed.

The M&A service providing system 10 is a system capable of complementing the disadvantages of the M&A process that was previously performed only offline by performing the M&A process by grafting it with blockchain technology.

The M&A service providing system 10 according to an embodiment of the present invention includes a main server 100, an M&A platform 200, a user terminal 300, a first exchange server 400, and a second exchange server 500. Can include. Here, each configuration of the M&A service providing system 10 shown in FIG. 1 is only exemplary, and some configurations may be added or omitted, and at least one configuration may be divided into separate configurations as necessary. And can be integrated.

The main server 100 is a server operated by a business entity providing an M&A service, and may store, update, and maintain overall control and various information of the M&A service. In FIG. 1, the main server 100 is shown as one server, but the scope of the present invention is not limited thereto and may be operated by dividing into at least two servers according to necessity (eg, network load distribution, etc.).

The main server 100 may upload at least one project to the M&A platform 200, and may process a response according to a request received from the M&A platform 200 by interworking with the M&A platform 200. . In particular, the main server 100 may store SPC information for at least one SPC (Special Purpose Company). SPC may refer to a special purpose corporation for conducting M&A negotiations for an acquisition target company, which is the target of M&A services, and SPC information may be determined when SPC is established. SPC information includes total amount, equity, terms (e.g., 7 years), condition (e.g., consignment of management rights), number of accounts, interest rate, expected income, and other information about the company to be acquired (e.g., member information, customer information, etc.) It may include.

The main server 100 may store SPC information for each of the first SPC (SPC1) to kth (k is an integer greater than or equal to 2) SPC (SPCk; not shown). In addition, the main server 100 may generate a project (Project1 to Projectk) for each SPC (SPC1 to SPCk) using SPC information of each SPC (SPC1 to SPCk) and upload it to the M&A platform 200. Each of the projects (Project1~Projectk) may include at least project identification information and stake information for the acquisition target company, and may include additional information if necessary.

The M&A platform 200 may include a database composed of a block chain, and may store projects (Project1 to Projectk) for each SPC (SPC1 to SPCk) uploaded by the main server 100 in the database. Here, the database may mean a transaction storage DB in the blockchain, and the integrity can be guaranteed as the projects (Project1 to Projectk) are stored in the chained block.

The M&A platform 200 has a structure composed of a block chain, and the main server 100 is independent of the block chain, so the M&A platform 200 is on-chain, and the main server 10 is off-chain. It can be called (off-chain). The main server 100 and the M&A platform 200 may be connected through an oracle, a link between off-chain and on-chain.

Oracle can convert off-chain information into a smart contract and deliver it on-chain, or interpret on-chain smart contracts and deliver them off-chain. Here, a smart contract is a command that can be executed in the blockchain when a predefined condition is satisfied, and can be included in a transaction.

The main server 100 can convert the project (Project1 ~ Projectk) for each SPC (SPC1 ~ SPCk) into the form of a smart contract so that it can be uploaded to the M&A platform 200 through Oracle and deliver it to the M&A platform 200. have.

Since the M&A platform 200 is composed of a block chain and cannot directly access data outside the network (eg, the main server 100), data can be imported from the outside through a smart contract. For example, any one node in the M&A platform 200 may create a transaction including a smart contract to view information on a specific project, and the Oracle, which has confirmed this, interprets the smart contract and analyzes the main server 100 ).

In addition, the M&A platform 200 may store transaction details of each of the first virtual currency (UCX) and the second virtual currency (UCC). Here, the first virtual currency (UCX) is an externally issued token by the business entity that provides the M&A service, and is affected by the situation of the exchange, and the second virtual currency (UCC) is instead of the stock of the acquisition target company for the investment of the project. As a special purpose token provided, it can be affected by the stock market. The second virtual currency (UCC) is independently generated, traded, and managed for each project (Project1 to Projectk), and may be expressed as UCC1 to UCCk, but hereinafter, it may be expressed as UCC for convenience of description. The transaction details of each of the first virtual currency UCX and the second virtual currency UCC may be updated by a transaction generated by each node 300, 400, 500 to be described later.

A more detailed configuration and operation of the M&A platform 200 will be described later with reference to FIGS. 3 to 4.

The user terminal 300 is an investor's terminal, and may be a device in which an M&A application distributed by a business entity providing an M&A service can be installed and executed. Here, the user terminal 300 may be a smart phone, a tablet, a notebook, a personal computer (PC), or the like, but the scope of the present invention is not limited thereto. The M&A application may be a program for providing an interface to a user to participate in an ongoing M&A negotiation. Specifically, the M&A application is an interface that allows you to view information on the SPC currently undergoing M&A negotiations, purchase or sell shares of the acquisition target company (i.e., participate in M&A negotiations), and each exchange server (400, 500). It is possible to provide an interface to users to perform cryptocurrency transactions by connecting to.

The user terminal 300 on which the M&A application is installed and executed may participate as one node constituting the block chain of the M&A platform 200. That is, the user terminal 300 may generate a transaction for viewing SPC information corresponding to a specific project, and may generate a transaction for buying or selling a stake in an acquisition target company corresponding to a specific project. Also, the user terminal 300 may verify a transaction generated by another user terminal.

The user terminal 300 may purchase a stake in an acquisition target company corresponding to a specific project using the first virtual currency (UCX). Specifically, the user terminal 300 may access the first exchange server 400 to exchange an investor's asset (eg, cash) into a first virtual currency (UCX). The user terminal 300 may generate a transaction for purchasing shares of a company to be acquired by using the owned first virtual currency (UCX). This transaction transfers the ownership of the first virtual currency (UCX) from the user terminal 300 to the holder of the stake in the acquisition target company and the ownership of the second virtual currency (UCC) corresponding to the first virtual currency (UCX). It may include a smart contract that transfers to the user terminal 300 from the holder of the stake in the acquisition target company. That is, the user terminal 300 purchases the stake of the acquisition target company corresponding to a specific project using the first virtual currency (UCX), and when the transaction is registered in the blockchain, the first virtual currency (UCX) Can be paid in a second virtual currency (UCC) corresponding to ). Accordingly, the user terminal 300 holding the second virtual currency (UCC) holds a stake in the acquisition target company, and the second virtual currency (UCC) may function as a stock affected by the stock market.

The user terminal 300 may hold the stake of the acquisition target company corresponding to a specific project in the form of a second virtual currency (UCC) and sell it at the request of an investor. Specifically, the user terminal 300 may access the second exchange server 500 and exchange the second virtual currency (UCC) into the first virtual currency (UCX). According to another embodiment, the user terminal 300 may access the second exchange server 500 and convert the second virtual currency (UCC) into another type of virtual currency (eg, bitcoin). Here, a specific process of converting the second virtual currency (UCC) to the first virtual currency (UCX) by the second exchange server 500 at the request of the user terminal 300 will be described later.

Although one user terminal 300 is illustrated in FIG. 1, a plurality of user terminals may participate as nodes constituting the block chain of the M&A platform 200.

The first exchange server 400 may function as an exchange that handles various virtual currencies traded on the market including the first virtual currency (UCX). In particular, the first exchange server 400 creates a smart contract for transferring the ownership of the first virtual currency (UCX) corresponding to the asset provided by the investor to the user terminal 300 according to the exchange request of the user terminal 300. A containing transaction can be generated and transferred to the M&A platform 200. Thereafter, when the first exchange server 400 confirms that the corresponding transaction has been registered in the blockchain, it may notify the user terminal 300 that the exchange transaction has been completed.

The second exchange server 500 manages the second virtual currency (UCC1-UCCk) corresponding to each project (Project1-Projectk) and transfers the second virtual currency (UCC1-UCCk) according to the exchange request of the user terminal 300. The corresponding first virtual currency (UCX) can be paid.

Specifically, the second exchange server 500 uses the second virtual currency (UCC1-UCCk) held by the user terminal 300 in response to the exchange request from the user terminal 300 to sell the stake of the acquisition target company. Can be created. This transaction corresponds to the content that the ownership of the second virtual currency (UCC1~UCCk) is transferred from the user terminal 300 to the purchaser (e.g., the corresponding SPC) of the acquisition target company and the second virtual currency (UCC1~UCCk) It may include a smart contract that transfers the ownership of the first virtual currency UCX to the user terminal 300 from the purchaser of the stake of the acquisition target company. That is, the user terminal 300 holds and sells the stake of the acquisition target company corresponding to a specific project through the second virtual currency (UCC1~UCCk), and when the transaction is registered in the blockchain, the second payment is reversed. It can be paid in the first virtual currency (UCX) corresponding to the virtual currency (UCC1~UCCk).

In FIG. 1, the user terminal 300, the first exchange server 400, and the second exchange server 500 are illustrated as being independent from the M&A platform 200, but the user terminal 300 and the first exchange server 400 ) And the second exchange server 500 may each operate as one node of the blockchain of the M&A platform 200.

2 is a block diagram illustrating the main server shown in FIG. 1 in more detail.

Referring to FIG. 2, the main server 100 may include an SPC information storage unit 110, an investor information storage unit 120, an authority determination unit 130, and an SPC information providing unit 140.

The SPC information storage unit 110 may store and manage SPC information of each SPC (SPC1 to SPCk). The SPC information storage unit 110 may transmit the SPC information to the SPC information providing unit 140 at the request of the SPC information providing unit 140.

The investor information storage unit 120 may store information on an investor who has installed an M&A application on the user terminal 300 and logged in (log-in). Here, the information on the investor may include identification information of the investor (eg, name, ID), visit record information (eg, a log record of a landing page), stake holding status, virtual currency holding status, membership level, and the like.

The authority determination unit 130 may determine whether to allow the user terminal 300 to request to view SPC information. Here, the SPC information viewing request is SPC information corresponding to a specific project that the user terminal 300 generates a transaction including a smart contract for viewing information on a specific project, and the smart contract is interpreted and transmitted by Oracle It may mean a request to read. The authority determining unit 130 may determine whether a request for accessing SPC information from a member having a legitimate authority is based on information about the investor in the investor information storage unit 120.

If the request for SPC information access is a request to view SPC information from a member with a legitimate authority, the authority determination unit 130 provides the SPC information providing unit so that the SPC information corresponding to the SPC information access request can be transmitted to the user terminal 300. You can control 140.

The SPC information providing unit 140 may retrieve SPC information from the SPC information storage unit 110 and transmit the SPC information to the user terminal 300 under the control of the authority determination unit 130. At this time, the SPC information is converted into the form of a smart contract by Oracle and transmitted into the M&A platform 200, and nodes other than the smart terminal 300 may be encrypted so that the corresponding SPC information cannot be viewed, and the smart terminal 300 ) Can be viewed by decrypting the encrypted SPC information using a private key stored by the M&A application.

3 is a diagram showing a block chain structure of the M&A platform shown in FIG. 1.

3, the block chain structure of the M&A platform 200 may have a multiplexed form. That is, the blockchain of the M&A platform 200 may be formed of a first chain layer and a second chain layer.

The first chain layer includes all nodes connected to the blockchain network, and includes a root block chain consisting of only blocks that have been finally verified.

Since the first chain layer includes all nodes distributed around the world connected to the blockchain network, a consensus algorithm for verifying transactions is parallel using a sharding protocol to increase the number of transactions that can be processed per second. So that it can be done.

Specifically, the first chain layer groups all nodes into M shards (shard1 to shardM), and a leader node is randomly selected from each of the grouped M shards (shard1 to shardM), and leader A node may collect node IDs (or node addresses) of all nodes in the shard to which the leader node belongs and broadcast it to the leader node of another shard. Here, M may be arbitrarily determined, and the number of nodes included in each shard may be the same or different for each shard.

On the other hand, transactions created by nodes belonging to a specific shard are verified according to the consensus algorithm inside the shard and included in the intermediate block, and the verified intermediate block is shared with other shards and verified according to the consensus algorithm between the shards, and is then added to the final block. Can be included. Here, the final block means a block included in the root blockchain. The fact that the transaction described in FIG. 1 is registered in the blockchain may mean that a block including the transaction is included in the root blockchain.

The consensus algorithm inside the shard uses a PoS (Proof of Stake) method in which the node with the highest age of the virtual currency (UCX or UCC) held among the nodes belonging to the shard has a high probability of generating a new block. Can be used. In addition, the consensus algorithm between shards uses a PoS method in which the node with the highest age of the virtual currency (UCX or UCC) held among the leader nodes of each of the shards (shard1 to shardM) has a high probability of generating a new block. I can.

Meanwhile, when shards (shard1 to shardM) are generated and a leader node is randomly selected, it is not performed once and fixed, but may be performed periodically. That is, the number of shards, nodes constituting each shard, and leader node may be randomly shuffled for each period. This can greatly contribute to lowering the risk of hacking into the blockchain network. The period of the shuffle can be appropriately selected so as not to increase the network load.

The first chain layer may be defined as an RPoS (Random Selection Proof of Stake) sharding protocol in that it is a sharding protocol that applies a consensus algorithm of a proof-of-stake method but periodically randomly shuffles.

According to the first chain layer, the number of transactions that can be generated per second can be increased by performing a consensus algorithm by dividing the entire node into a plurality of shards (shard1 to shardM).

The second chain layer represents a block chain structure inside each shard of the first chain layer, and may have a plasma block chain structure. Here, the first shard (shard1) among the plurality of shards (shard1 to shardM) is described as an example, but the same structure and operation may be applied to other shards (shard2 to shardM).

The second chain layer may be composed of first to Nth (N is an integer greater than or equal to 2) sub-chains (sub-chain1 to sub-chainN) included in the first shard1. Nodes belonging to the first shard (shard1) may participate in any one of the first to Nth sub-chains (sub-chain1 to sub-chainN), but the participation may not be forced. In this specification, it is assumed that each of the nodes belonging to the first shard1 participates in any one of the first to Nth sub-chains (sub-chain1 to sub-chainN) and operates as a client. .

Each of the first to Nth sub-chains (sub-chain1 to sub-chainN) is a plasma chain, and may be a child chain for a root chain, which is a parent chain.

Each of the first to Nth sub-chains (sub-chain1 to sub-chainN) operates according to an internal consensus algorithm, and according to an embodiment, the consensus algorithm may be PoS. That is, when any one node generates a transaction, the block generator according to the PoS of the sub-chain to which the node belongs verifies the transaction to generate the plasma block, and the hash value of the plasma block header is the first chain layer. It can be included in the transaction at and finally included in the root chain. Here, the hash value of the header of the plasma block containing the transaction, not the transaction generated by the node itself, is stored in the root chain, so that transactions included in the plasma block, which are substantially lower blocks, are stored in the root chain. Therefore, it is possible to reduce the network load.

FIG. 4 is a diagram illustrating a process of including a final block in a root chain in the block chain structure of FIG. 3.

4, when nodes belonging to each of the first to Nth sub-chains (sub-chain1 to sub-chainN) in the second chain layer generate transactions (transaction sub-chain1 to transaction sub-chainN), the first To Nth sub-chains (sub-chain1 to sub-chainN), each transaction is verified according to an internal consensus algorithm (e.g., PoS), and the block generator can generate a plasma block by collecting the verified transactions. .

The hash value of the header of the plasma block generated in each of the first to Nth sub-chains (sub-chain1 to sub-chainN) is a transaction generated by a node belonging to the first shard (shard1) of the first chain layer (transaction shard1) Can be included in In FIG. 4, only the transaction (transaction shard1) is illustrated, but the same method may be applied to the remaining transactions (transaction shard2 to transaction shardM).

Each transaction (transaction shard1 to transaction shardM) may be verified in each of the first to Mth shards (shard1 to shardM) according to an internal consensus algorithm (eg, PoS) and included in the intermediate block. The intermediate block for which verification has been completed may be shared with other shards, verified according to a consensus algorithm (eg, PoS) between shards, and included in the final block.

As described in Figs. 3 and 4, as the method according to the RPoS sharding protocol of the first chain layer and the plasma blockchain method of the second chain layer are applied in combination, the smart contract included in the transaction is processed more quickly. And the number of transactions that can be processed per second can be significantly increased.

FIG. 5 is a flowchart illustrating an example of a method for purchasing shares in the M&A service providing system shown in FIG. 1.

5, SPC, a special-purpose corporation for conducting M&A negotiations for a company to be acquired, is established, and when the SPC is established, the total amount, equity, terms (eg, 7 years), conditions (eg, management rights consignment) ), the number of accounts, interest rate, expected revenue, and other information on the acquisition target company (eg, member information, customer information, etc.), and the SPC information may be determined (S100).

The main server 100 may collect information for M&A negotiation of each SPC (SPC1 to SPCk), create a project (Project1 to Projectk) for each SPC (SPC1 to SPCk), and upload it to the M&A platform 200. (S110).

The M&A platform 200 may store projects (Project1 to Projectk) for each SPC (SPC1 to SPCk) uploaded by the main server 100 in a database (i.e., the root blockchain) composed of a block chain (S120).

The user terminal 300 on which the M&A application has been installed and executed can participate as one node constituting the block chain of the M&A platform 200, and is a transaction to view SPC information corresponding to a specific project according to the user's inquiry request. Can be created. These transactions are interpreted by Oracle, and the request for SPC information access is transmitted to the main server 100. In the case of a request for accessing SPC information from a member with the right authority, the main server 100 transmits the SPC information corresponding to the request for access to the SPC information It can be transmitted to the user terminal 300 through (S130).

The user may analyze the provided SPC information and determine whether to purchase a stake in the acquisition target company (S140).

If the user decides to purchase the shares of the acquisition target company corresponding to a specific project, the user terminal 300 makes a request for exchange for the purchase of the first virtual currency (UCX) through the M&A application, the first exchange server 400 The first exchange server 400 is for transferring the ownership of the first virtual currency (UCX) corresponding to the asset provided by the investor to the user terminal 300 according to the exchange request of the user terminal 300. A transaction including a smart contract can be generated and transferred to the M&A platform 200. Thereafter, when the first exchange server 400 confirms that the corresponding transaction has been registered in the block chain, it may notify the user terminal 300 that the exchange transaction has been completed (S150).

The user terminal 300 may generate a transaction (ie, a share purchase request) to purchase a share of the acquisition target company using the held first virtual currency (UCX) (S160). This transaction transfers the ownership of the first virtual currency (UCX) from the user terminal 300 to the holder of the stake in the acquisition target company and the ownership of the second virtual currency (UCC) corresponding to the first virtual currency (UCX). It may include a smart contract that transfers to the user terminal 300 from the holder of the stake in the acquisition target company.

The transaction corresponding to the share purchase application may be verified through the first chain layer and the second chain layer of the M&A platform 200 and finally registered in the root blockchain (S170).

When it is confirmed that the transaction corresponding to the share purchase application has been registered in the root blockchain (S180), the user terminal 300 receives the corresponding acquisition by receiving a second virtual currency (UCC) corresponding to the first virtual currency (UCX). It is possible to hold a stake in the target company (S190).

FIG. 6 is a flowchart illustrating an example of a method of selling shares in the M&A service providing system shown in FIG. 1.

Referring to FIG. 6, the user terminal 300 in which the M&A application is installed and executed may generate a transaction for viewing SPC information corresponding to a specific project according to a user's inquiry request. These transactions are interpreted by Oracle and the request for SPC information access is transmitted to the main server 100, and in the case of a request to view SPC information from a member with the right authority, the main server 100 sends SPC information corresponding to the SPC information request. It can be delivered to the user terminal 300 through Oracle (S200).

The user may analyze the provided SPC information and determine whether to sell the stake of the acquisition target company (S210).

If the user decides to sell the stake of the acquisition target company corresponding to a specific project, the user terminal 300 makes a request for currency exchange for selling the second virtual currency (UCC) through the M&A application. It can be transmitted to (S220).

The second exchange server 500 uses a second virtual currency (UCC1-UCCk) held by the user terminal 300 in response to a currency exchange request from the user terminal 300 to sell the stake of the acquisition target company (i.e. Stock sale application) may be generated (S230). This transaction corresponds to the content that the ownership of the second virtual currency (UCC1~UCCk) is transferred from the user terminal 300 to the purchaser (e.g., the corresponding SPC) of the acquisition target company and the second virtual currency (UCC1~UCCk) It may include a smart contract that transfers the ownership of the first virtual currency UCX to the user terminal 300 from the purchaser of the stake of the acquisition target company.

The transaction corresponding to the stake sale application may be verified through the first chain layer and the second chain layer of the M&A platform 200 and finally registered in the root blockchain (S240).

When it is confirmed that the transaction corresponding to the stake sale application has been registered in the root blockchain (S250), the second exchange server 500 may notify the user terminal 300 that the exchange transaction for the stake sale has been completed (S260). .

The user terminal 300 may hold funds obtained by selling a stake in a corresponding acquisition target company by receiving the first virtual currency UCX corresponding to the second virtual currency UCC (S270). It goes without saying that the user terminal 300 may later convert the held first virtual currency (UCX) into another type of virtual currency or cash through the first exchange server 400.

FIG. 7 is a flowchart illustrating an example of a method for liquidating a corporation in the M&A service providing system shown in FIG. 1.

Referring to FIG. 7, when a predetermined period (eg, 7 years) at the time of establishment of the SPC expires, the corresponding SPC enters a corporate liquidation procedure, and the SPC may be converted into a liquidation corporation (S300).

When the liquidation procedure of a specific SPC starts, the main server 100 calculates a dividend per share by subtracting the settlement amount (eg, initial input cost + corporate operating cost) from the total amount of SPC information of the SPC by dividing the dividend by the total number of accounts. It can be done (S310). Here, the dividend per share may be converted into a unit of the first virtual currency (UCX).

The main server 100 may transmit a dividend distribution request to the M&A platform 200 to distribute dividends to the user terminal 300 (S320). The dividend distribution application may be converted into a smart contract form by Oracle and delivered to the M&A platform 200. The smart contract may include identification information of the SPC in which the liquidation procedure is initiated, dividend per share, and information requesting that the second exchange server 500 execute dividend distribution.

The transaction including the smart contract corresponding to the dividend distribution application may be verified through the first chain layer and the second chain layer of the M&A platform 200 and finally registered in the root blockchain (S330).

The second exchange server 500 may confirm that a transaction including a smart contract corresponding to the dividend distribution application is registered in the root blockchain (S340).

The second exchange server 500 uses a second virtual currency (UCC) held by the user terminal 300 and a first virtual currency (UCX) allocated to the user terminal 300 based on the dividend per share according to the dividend distribution application. Can be calculated. For example, since the dividend per share may mean the first virtual currency (UCX) per account, the dividend is allocated to the user terminal 300 through a multiplication operation with the second virtual currency (UCC) held by the user terminal 300. The first virtual currency (UCX) may be calculated.

The second exchange server 500 may generate a transaction (ie, request for stock arrangement) for organizing the stakes of the acquisition target company (S350). This transaction includes the transfer of ownership of the second virtual currency (UCC) held by the user terminal 200 from the user terminal 300 to the liquidation corporation, and the first virtual currency (UCX) allocated to the user terminal 300. It may include a smart contract that transfers ownership from the liquidation corporation to the user terminal 300.

The transaction corresponding to the stake arrangement application may be verified through the first chain layer and the second chain layer of the M&A platform 200 and finally registered in the root blockchain (S360).

When it is confirmed that the transaction corresponding to the stake arrangement request has been registered in the root blockchain (S370), the second exchange server 500 may notify the user terminal 300 that the dividend distribution due to the liquidation of the SPC has been completed ( S380).

The user terminal 300 may hold a dividend due to the liquidation of the SPC by receiving the first virtual currency UCX corresponding to the stake (that is, the second virtual currency UCC) held (S390). It goes without saying that the user terminal 300 may later convert the held first virtual currency (UCX) into another kind of virtual currency or cash through the first exchange server 400.

According to the block chain-based M&A service providing system 10 according to an embodiment of the present invention, an M&A service can be provided using a block chain, thereby providing an investment opportunity in the M&A field, which was difficult for general investors to access.

In addition, it is possible to replace the participation and cost of experts, which were essential to ensure the reliability of the transaction process for the stake of the acquisition target company, by using blockchain technology with integrity and reliability.

In addition, the problem of personal information that was indiscriminately leaked during the existing M&A negotiation process can be solved by encrypting and providing personal information to users with legitimate authority through a blockchain-based platform.
