Description

Dividend distribution system and method based on security token

The invention relates to a dividend distribution system and method, in particular to a dividend distribution system and method based on securities tokens.

In recent years, with the popularization and vigorous development of the dividend distribution system (that is, dividend distribution or bonus distribution), various dividend distribution methods have sprung up, among which stock dividends and floating bonuses are the most common.

Generally speaking, for start-ups or unlisted companies, dividend measures are usually realized by allocating stocks, but stock-related dividend measures have the problem of not being transparent enough and difficult to realize. For example, since the company is not listed, its financial status is not disclosed, making it difficult to verify the company’s dividend measures, and there may even be black box operations and excessive stock issuance. Furthermore, if the stocks are not publicly issued, if the holders want to realize cash, they can only trade through privately matched channels or intermediaries. The trading prices and methods are not as convenient, transparent and secure as publicly listed stocks, so it is easy to use Investors or holders suffer losses, for example, it is difficult for the transaction price to grow when the buyer is worried about being scammed by unlisted stocks.

In summary, it can be seen that in the prior art, there have been problems of difficulty in realizing dividends and insufficient transparency for a long time. Therefore, it is really necessary to propose improved technical means to solve this problem.

The invention discloses a dividend distribution system and method based on securities tokens.

First of all, the present invention discloses a dividend distribution system based on security tokens, which is applied in a blockchain network. The system includes a transaction terminal host and an issuing terminal host. Wherein, the transaction terminal host is used to allow the execution of the security token contract of the blockchain network. Then, in the part of the issuing end host, it includes: an initial module, a hosting module, an issuing module, a buying module, and a processing module. The initial module is used to pre-publish security token contracts and bonus contracts on the blockchain network. Among them, the security token contract includes the issuance conditions, the release time interval, the participants and the amount of bonuses allocated, and the bonus contract Contains the contract status of the first phase and the second phase; the escrow module is connected to the initial module to send multiple digital currencies to the bonus contract address of the bonus contract in advance, so that the bonus contract holds and escrows the digital currency; The group connects the initial module to execute the token issuing function of the security token contract, which is used to send corresponding N security tokens to the participating distributors according to the bonus amount of the participating distributors, where N is a positive number ; The setting module is connected to the initial module, used to execute the price setting function of the bonus contract, used to set the exchange price and exchange time conditions of security tokens and digital currencies; the buy module is connected to the hosting module and the issuing module And the setting module is used to set the contract status of the bonus contract to the first stage when the issuance conditions and time interval are met, so as to allow the participating distributors to execute the security token contract through the trading terminal host, and the participating distributors The held security tokens are sent to the bonus contract, so that when the exchange time conditions are met, the received security tokens are converted into equivalent digital currencies based on the exchange price to send to the corresponding participating distributors ; And the processing module is connected to the buy module, so that at the end of the first stage, the issuing host sets the contract status of the bonus contract to the second stage, so that the bonus contract selects the security type received in the first stage The tokens are re-sent to the corresponding participating distributors, sent to the custody account or destroyed.

In addition, the present invention discloses a dividend distribution method based on security tokens, which is applied to a blockchain network with an issuing host and a transaction host. The steps include: the issuing host pre-publishes the security token on the blockchain network. Token contract and bonus contract. Among them, the security token contract includes the issuing conditions, the issuing time interval, the participating distributors and the amount of bonuses allocated, and the bonus contract includes the contract status of the first and second stages; the issuing end host Send multiple digital currencies to the bonus contract address of the bonus contract in advance, so that the bonus contract holds and manages the digital currency; the issuing end host executes the token issuing function of the security token contract to distribute the bonus according to the participants Send the corresponding N security tokens to the participating distributors respectively, where N is a positive number; the issuing host executes the price setting function of the bonus contract to set the exchange price and exchange time of the security tokens and digital currencies Conditions; when the issuing end host has met the issuing conditions and the issuing time interval, the contract status of the bonus contract is set to the first stage to allow the participating distributors to execute the security token contract through the trading end host, and the participating distributors will hold Send the security tokens to the bonus contract so that when the exchange time conditions are met, the bonus contract will convert the received security tokens into equivalent digital currencies based on the exchange price to send to the corresponding participating distributors; and When the first stage ends, the issuing host sets the contract status of the bonus contract to the second stage, so that the bonus contract chooses to resend the security tokens received in the first stage to the corresponding participating distributors and send them to Keep the account or destroy it.

The system and method disclosed in the present invention are as above. The difference from the prior art is that the present invention uses the issuing host to issue security token contracts and bonus contracts on the blockchain network, and enables the bonus contracts to hold and escrow digital currencies. , Then, according to the bonus amount of the participating distributors, execute the security token contract on the issuing end host and send the security tokens to the participating distributors. When the distribution conditions and the issuance time interval are met, the participating distributors are allowed to execute through the trading end host The bonus contract is used to convert the held security tokens into equivalent digital currencies, and choose to re-send the converted security tokens to the corresponding participating distributors, send to the custody account or destroy them.

Through the above technical means, the present invention can achieve the technical effect of improving the liquidity and transparency of dividends.

Hereinafter, the implementation of the present invention will be described in detail with the drawings and embodiments, so as to fully understand and implement the implementation process of how the present invention uses technical means to solve technical problems and achieve technical effects.

Before explaining the security token-based dividend distribution system and method disclosed in the present invention, the terms defined by the present invention will be explained first. The participating distributors in the present invention refer to those who are allowed to participate in dividends, such as: Employees, shareholders, token holders, etc. The digital currency refers to Bitcoin, Ethereum, etc., and the difference between the Security Token and the digital currency is that the latter has its own independent blockchain, while the former is based on an existing area. It runs on the block chain and is supported by physical assets (for example: shares, cash, real estate, or any valuable rights and vouchers, etc.). For example, the ether used in the block chain of Ethereum is digital Currency, but on this blockchain, you can also use standards such as ERC20, ERC721, ERC1400, or ERC1410 to establish various tokens (Tokens) running on this blockchain and supported by physical assets with Smart Contracts. Security tokens.

Then, the "securities token contract" and "bonus contract" both refer to smart contracts deployed on the blockchain network. In fact, the smart contract refers to a computer program that drives the execution of instructions based on established conditions and transmitted information. Specifically, the smart contract uses a programming language, such as Solidity, Serpent, LLL, EtherScript, Sidechain, etc. It can include various functions, events, parameter states, etc., take "Ethereum" as an example. The smart contract is compiled to obtain binary code and apply binary interface ( Application Binary Interface, ABI) in order to broadcast the smart contract to the blockchain network, waiting for the miner or validator to put the smart contract on the blockchain and get the corresponding address, so far through the blockchain The transaction completes the release of the smart contract. After that, each node can execute the corresponding smart contract according to this address, and use different commands to change the state of the smart contract on the blockchain and detect whether the event is triggered. In actual implementation, the "securities token contract" described in the present invention includes functions that can directly define how many security tokens the account has, that is, it has the function of issuing security tokens; the "bonus contract" includes functions for The function of purchasing security tokens, and after the purchase, the bonus contract has the ownership of the purchased security tokens, that is, after the bonus contract purchases the security tokens, it has the ownership of the purchased security tokens ownership. With this ownership, when the bonus contract is executed, the security tokens purchased by the bonus contract can be directly sent to others, such as those participating in the distribution. In other words, the issuing host can be regarded as the seller of security tokens, and the bonus contract can be regarded as the buyer. When the bonus contract purchases security tokens from the issuing host, the ownership of these purchased security tokens The right is transferred from the issuing end host to the bonus contract. Therefore, the future transfer of these security tokens purchased by the bonus contract must also go through the bonus contract. When you want to transfer out security tokens (for example: resending to participating distributors), you must also transfer the security tokens through this bonus contract.

The following diagrams will further explain the dividend payment system and method of the present invention based on security tokens. Please refer to "Figure 1" first. "Figure 1" is the system of the present invention based on security token dividend payment system. The block diagram is applied to the blockchain network 130. This system includes: a transaction end host 110 and an issuing end host 120. These hosts can be regarded as nodes of the blockchain network 130 and are connected to each other in a point-to-point manner. In fact, computer devices such as personal computers, notebook computers, and servers can be used to implement these hosts. Among them, the transaction terminal host 110 is used to allow the execution of the security token contract of the blockchain network 130, for example: execute the function of the security token contract, so as to send the security tokens held by the participating distributors to the bonus Contract, the bonus contract converts the received security tokens into equivalent digital currencies. In actual implementation, security token contracts can use standards that meet "ERC20", "ERC1400" or "ERC1410" to send and give tokens, namely: security tokens, and can be set in the security token contract Issuing conditions (such as holding for a certain period of time) and issuing time interval (for example: setting monthly, quarterly, yearly, or irregularly, etc.) in order to give different security tokens to different participants (such as employees) (Can be regarded as shares). Among them, the issuing conditions can include the granting rules (Vesting Rules) and the shortest effective period (Cliff). Later, we will illustrate the granting rules and the shortest effective period with the diagram.

The issuing end host 120 includes an initial module 121, a hosting module 122, an issuing module 123, a setting module 124, a buying module 125, and a processing module 126. Among them, the initial module 121 is used to pre-publish security token contracts and bonus contracts on the blockchain network 130, where the security token contracts include issuance conditions, issuance time intervals, participating distributors, and bonuses allocated Quantity; the bonus contract includes the contract status of the first phase and the second phase. In actual implementation, the issuing end host 120 can execute the bonus setting function of the security token contract to set the bonus amount of the participating distributors according to the preset bonus amount. In addition, when the contract status of the bonus contract is in the first stage, it can be regarded as the buying stage, allowing the participating distributors to send security tokens into the bonus contract through the security token contract. At this time, the bonus contract will buy the security token. Then, the corresponding digital currency is sent to the corresponding participating distributors. At this point, the transaction of purchasing security tokens in a bonus contract is completed; when the contract status of the bonus contract is in the second stage, it can be regarded as the issuing stage to receive The obtained security tokens are issued to the corresponding participating distributors, or distributed to the custody account so that the issuing host 120 can recover the security tokens, or even directly destroy the security tokens to achieve the purpose of capital reduction.

The escrow module 122 is used to send the digital currency to the bonus contract address of the bonus contract in advance, so that the bonus contract holds and escrows the digital currency. The holding and escrow described here means that the issuing host 120 except for issuing securities In addition to tokens, digital currencies (such as Bitcoin, Ether, etc.) will be sent to the address of the bonus contract so that the digital currency can be managed by the bonus contract (at this time, the owner of the digital currency is the bonus Contract), also known as "holding" and "escrow". In actual implementation, the issuing host 120 can first purchase digital currency using legal currency on the exchange, and then send the purchased digital currency to the bonus contract address of the bonus contract. The digital currency may include Bitcoin, Ether, and stable currency. (Or called constant currency) and so on. In particular, the amount of digital currency purchased needs to be equal to the bonus to be distributed.

The issuing module 123 is used to execute the token issuing function of the security token contract, and is used to send corresponding N security tokens to the participating distributors according to the bonus amount of the participating distributors, where N is a positive number. For example, assuming that the bonus amount of the parameter is 100, when the token issuance function is executed, 100 security tokens can be sent to the account address of the participating distributor through a blockchain transaction. For this example, The source address of the blockchain transaction is the address of the custodial account, the destination address is the account address of the participating distributor, and the number is 100.

The setting module 124 is used to execute the price setting function of the bonus contract, and is used to set the exchange price and exchange time conditions of the security token and the digital currency. In other words, set the price at which security tokens are traded in digital currencies (which can be regarded as the amount of digital currency required to buy security tokens), and the time allowed for exchange, such as a certain point in time , Or a certain time range, etc. Assuming that the exchange price is 5, it means that five digital currencies are needed to exchange for a security token. In actual implementation, the exchange price can also be presented as a ratio. For example, suppose that the exchange price is set to "1:2", which means that two digital currencies can be exchanged for one security token. Although the present invention uses the above examples to illustrate the exchange price, it is not limited thereto. In fact, as long as the amount of digital currency required to buy security tokens can be known, it does not deviate from the scope of application of the present invention. For example, In other words, the exchange price can also directly use the price of a third-party decentralized exchange, or calculate and adjust it based on this price.

The buy module 125 is used to set the contract status of the bonus contract to the first stage when the issuance conditions and the issuance time interval are met, so as to allow the participating distributors to execute the security token contract through the trading terminal host 110 and participate in the distribution The security tokens held by the participants are sent to the bonus contract, so that when the exchange time conditions are met, the received security tokens will be converted into equivalent digital currencies based on the exchange price to be sent to the corresponding participating distribution By. In actual implementation, the distribution conditions include the awarding rules and the shortest effective period. Among them, the awarding rules are the rules for the distribution of dividends. For example, the number of bonuses distributed is divided into four years, and 10% is given when the first year expires. 10% is given in the second year, 40% in the third year, and 40% in the fourth year. In this case, the shortest effective period is one year. Later, in conjunction with the diagram, it will be explained in detail how the security tokens held by the participating distributors are converted into equivalent digital currencies.

The processing module 126 is used for, at the end of the first stage, the issuing host 120 sets the contract status of the bonus contract to the second stage, so that the bonus contract chooses to resend the security tokens received in the first stage to the corresponding Participating in the distribution, sending to a custody account or destroying, these three alternative methods can be regarded as distribution rules. In actual implementation, assuming the use of Ethereum's blockchain network, because calculations will consume gas (Gas), if it is difficult to send all security tokens in a blockchain transaction, you can call multiple times The same function to complete the transaction. In addition, if the contract logic allows for free issuance or destruction in the second stage, you can call the resend function to resend the security tokens to the corresponding participating distributors, or call the destruction function to destroy the security tokens , You can even call the recovery function to send the security tokens to the custody account, so that the security tokens can be recovered from the accounts of the participating distributors. Wherein, the custody account refers to the account used by the issuing host 120 to provide security tokens. For example, if one hundred thousand security tokens are to be issued, initially, this custody account will be set to one hundred thousand. Security tokens, and security tokens can be transferred through blockchain transactions, such as: transferring security tokens to the account addresses of participating distributors, or recovering security tokens from bonus contracts. In addition, the processing module 126 can also continuously detect events generated by security token contracts and bonus contracts. For example, the smart contract generates corresponding events during large-volume or overclocking transactions, so that the processing module 126 can detect When the occurrence of the event is detected, select Disable blockchain transactions (it can be regarded as prohibiting/disabling blockchain transactions, that is, when the processing module 126 detects the occurrence of the event, it will not allow Perform blockchain transactions until the event does not exist) or generate a corresponding notification message to notify the participating distributors in real time. For example, assuming that an overclocking transaction event has been detected, the processing module 126 can generate Text such as "transaction" is used as a notification message, and the notification message is sent to the participating distributors through at least one of instant messaging software, e-mail, and SMS.

In particular, it should be noted that in actual implementation, each module described in the present invention can be implemented in various ways, including software, hardware, or any combination thereof. For example, in some embodiments, each module can be It can be implemented by software and hardware or one of them.

Please refer to "Figure 2". "Figure 2" is a flow chart of the method for issuing dividends based on security tokens of the present invention, which is applied to a blockchain network 130 with a transaction terminal host 110 and an issuer host 120. The steps include: the issuing end host 120 pre-publishes a security token contract and a bonus contract on the blockchain network 130, where the security token contract includes issuance conditions, issuance time interval, participants in the distribution and their distribution The bonus amount. The bonus contract includes the first and second phases of the contract status (step 210); the issuing host 120 sends the digital currency to the bonus contract address of the bonus contract in advance, so that the bonus contract holds and escrows the digital currency (step 210). 220); the issuing end host 120 executes the token issuing function of the security token contract to send corresponding N security tokens to the participating distributors according to the bonus amount of the participating distributors, where N is a positive number ( Step 230); the issuing host 120 executes the price setting function of the bonus contract to set the exchange price and exchange time conditions of the security tokens and digital currencies (step 240); the issuing host 120 is in the issuing conditions and the issuing time interval When it has been satisfied, the contract status of the bonus contract is set to the first stage to allow the participating distributors to execute the security token contract through the trading terminal host 110, so as to send the security tokens held by the participating distributors to the bonus contract , To make the bonus contract when the exchange time conditions are met, according to the exchange price, convert the received security tokens into equivalent digital currencies to send to the corresponding participating distributors (step 250); when the first phase ends , The issuing end host 120 sets the contract status of the bonus contract to the second stage, so that the bonus contract can choose to resend the security tokens received in the first stage to the corresponding participating distributors, send to the custody account, or destroy (Step 260). Through the above steps, the security token contract and bonus contract can be released on the blockchain network 130 through the issuing host 120, and the bonus contract can hold and escrow the digital currency. Then, according to the bonus amount of the participating distributors Execute the security token contract on the issuing end host 120 and send the security token to the participating distributors. When the issuance conditions and the issuance time interval are met, the participating distributors are allowed to execute the bonus contract through the trading end host 110 to transfer the holding Converted security tokens into equivalent digital currencies, and choose to re-send the converted security tokens to the corresponding participating distributors, send them to a safekeeping account, or destroy them.

The following description will be given in the form of an embodiment in conjunction with "Figure 3" to "Figure 5". Please refer to "Figure 3" first. "Figure 3" is a schematic diagram of applying the present invention to set the parameters of a security token contract. . Before issuing the security token contract, the company manager can open the setting window 300 on the issuer host 120 to set the parameter status of the security token contract, for example: set participation in the distribution in the input block (311~314) Award rules and minimum effective period For example, in the input block 311, you can enter the account address of the participating distributors to receive security tokens, such as: "0x13ad5......"; enter the bonus amount in the input block 312; enter the grant in the input block 313 Rules; enter the shortest effective period in the input block 314. Among them, assuming that the awarding rule is "1,10;2,10;3,40;4,40." can represent 10% of the amount of bonuses awarded in the first year and 10% of the amount of bonuses awarded in the second year. Forty percent of the amount of bonuses awarded in the third year and 40% of the amount of bonuses awarded in the fourth year, which means that the amount of bonuses is divided into four years and awarded in different proportions. Assuming that the shortest effective period is the value "1", it can mean that this payment condition will only take effect after one year of employment, and no bonus will be issued for less than one year. Assuming that the input block (313, 314) is not entered, it can represent that the sending condition is to send security tokens at one time directly according to the amount of bonus. In particular, the above is the setting of a single participating distributor as an example. However, in actual implementation, the setting window 300 can provide a setting method for multiple participating distributors so as to provide company managers with different participation distributions. The person makes the corresponding settings. After entering the relevant settings of all participating distributors, you can click the OK component 315 to complete the parameter setting of the security token contract. The issuing end host 120 will generate the corresponding security token contract according to these parameter settings and publish it in the district On the blockchain network 130, and get the corresponding address, that is, the security token contract address.

Next, please refer to "Figure 4". "Figure 4" is a schematic diagram of applying the present invention to set the parameters of the bonus contract. Before issuing the bonus contract, the company manager can open the setting window 400 on the host 120 of the issuer to set the parameter status of the bonus contract, for example: set the exchange price and exchange time of security tokens and digital currencies in the input block 411 Conditions, and selection of distribution rules in the selection component 412, such as: resending to the original participating distributor, sending to a custody account, or destroying. Then, after clicking the confirmation element 413, the parameter setting of the bonus contract is completed. The issuing host 120 will generate the corresponding bonus contract according to these parameter settings, and publish it on the blockchain network 130 and obtain the corresponding address, namely : Bonus contract address. In addition, the security token contract address will be used as a parameter into the bonus contract. In particular, the company manager can also click on the whitelist component 414 to set the participating distributors and their corresponding source addresses that are allowed to trade security tokens, as well as the transaction upper limit of this source address, so as to limit where the bonus contract can go Some participating distributors purchase security tokens and the maximum number of purchases.

As shown in "Figure 5", "Figure 5" is a schematic diagram of applying the present invention to convert security tokens held by participating distributors into equivalent digital currencies. When participating distributors want to realize the security currency they hold, they can open the trading window 500 on the trading terminal host 110. If the contract status of the bonus contract is the first stage, the participating distributors are allowed to execute the securities based on the trading terminal host 110 The token contract sends the security tokens held by the participating distributors to the bonus contract, so that when the exchange time conditions are met, the bonus contract will convert the received security tokens into equivalent digital currencies based on the exchange price In order to be sent to the corresponding participating distributors, this conversion may involve different public chains through cross-chain technology, such as: Bitcoin's public chain, Ether's public chain, and so on. For example, the participating distributor can enter the number of security tokens to be converted in the input block 511, such as a value of 100. When the participating distributor clicks on the conversion element 512, a corresponding amount of security tokens will be sent to the bonus contract, so as to be converted into equivalent digital currencies according to the exchange price. After that, participants in the distribution can sell the acquired digital currency at each digital currency exchange to obtain the equivalent legal currency, or directly acquire the digital currency for consumption. In this way, the liquidity and value of security tokens can be enhanced, and the liquidity of dividends can be improved. On the other hand, since the smart contract logic for dividends can be made public, all personnel can know the dividend mechanism and the flow of securities tokens, which is highly transparent, and can even calculate the company’s profitability and further increase other Investor’s willingness to invest.

In summary, it can be seen that the difference between the present invention and the prior art is that the issuing end host publishes the security token contract and bonus contract on the blockchain network, and enables the bonus contract to hold and escrow digital currency. Then, According to the bonus amount of the participating distributors, execute the security token contract on the issuing end host and send the security tokens to the participating distributors. When the issuance conditions and the issuance time interval are met, the participating distributors are allowed to execute the bonus contract through the trading end host. Used to convert the held security tokens into digital currencies of equivalent value, and choose to re-send the converted security tokens to the corresponding participating distributors, send to the custody account or destroy them, by this technical means It can solve the problems of the previous technology, and then achieve the technical effect of improving the liquidity and transparency of dividends.

Although the present invention is disclosed in the foregoing embodiments as above, it is not intended to limit the present invention. Anyone familiar with similar art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of patent protection shall be determined by the scope of the patent application attached to this specification.
