After that, the trading server can pair the seller client to hang the sell order in the pending order clearing smart contract and the buyer client hangs the pending order clearing smart contract. Paying the bill, when the trading server successfully pairs the buy and sell orders, the pending bill clearing smart contract triggers the asset smart contract to execute the transaction and clearing of the number of trading units successfully paired, so as to solve the problems of the prior art and can achieve the technology to avoid transaction fraud. efficacy.

The features and embodiments of the present invention will be described in detail below with reference to the drawings and embodiments, which are sufficient to enable those skilled in the art to fully understand the technical means to which the present invention solves the technical problems, and The achievable effects of the present invention.

The invention can make the buyer and the seller of the asset hang the purchase order and the sell order in the pending order clearing smart contract, so that when the buy order and the sell order are successfully paired, the asset smart contract is triggered to execute the asset transaction and liquidation through the pending order clearing smart contract. The assets mentioned in the present invention may be quantifiable items or energy, such as gold, stocks, electric power, etc., but the invention is not limited thereto.

The smart contract (including the pending order clearing smart contract and the asset smart contract) is a code that can be executed by a computer and has a smart contract address. The smart contract address (including the pending order clearing contract address corresponding to the pending order clearing smart contract and the asset contract address corresponding to the asset smart contract) is sufficient for the device or device supporting the blockchain technology ( Node) obtains the data of the corresponding smart contract entity, for example, the value of a certain variable in the smart contract entity in a specific block in the blockchain.

In the following, the system operation of the present invention will be described with reference to the system architecture diagram of the smart contract digitally quantifiable asset and transaction in the "FIG. 1". As shown in FIG. 1, the system of the present invention includes a storage server 110, a seller client 120, a buyer client 130, and a transaction server 150. The storage server 110, the seller client 120, the buyer client 130, and the transaction server 150 can be directly or indirectly connected to the blockchain network.

The vault server 110 can provide a connection to the vendor client 120 and can be coupled to the transaction server 150. The storage server 110 can be connected to the seller client 120 and/or the transaction server 150 via a wired network such as Ethernet or a wireless network such as WiFi or Zigbee, but the invention is not limited thereto.

The custodial server 110 is responsible for generating asset intelligence contracts. In general, the custodial server 110 can pre-store smart contract templates and generate asset smart contracts based on pre-stored smart contract templates when an asset intelligence contract needs to be generated. The storage server 110 can generate corresponding smart contracts for different assets, for example, an asset smart contract corresponding to gold, an asset smart contract corresponding to a specific energy, and the like.

The vault server 110 is also responsible for publishing the generated asset smart contracts into the blockchain. In more detail, the vault server 110 can generate a blockchain transaction containing the generated asset smart contract and send the generated blockchain transaction to the blockchain network, in the blockchain network. After receiving the blockchain transaction sent by the custodial server 110, the verification node may create a block containing the asset smart contract in the received blockchain transaction, and send the created block to the blockchain network. Synchronization in the road. When the block sent to the blockchain network is accepted, the block sent to the blockchain network is added to the end of the blockchain, so the asset smart contract contained in the block It can be published to the blockchain.

The vault server 110 is also responsible for obtaining the asset contract address corresponding to the issued asset smart contract while issuing the asset smart contract to the blockchain, and transmitting the obtained asset contract address to the transaction server 150.

The custodial server 110 is also responsible for increasing the number of transaction units corresponding to the occupant in the generated asset smart contract based on the assets provided by the occupant (also referred to as "transaction unit number" in the present invention). The owner of the asset can provide the owned assets to the unit, organization or organization that owns the server 110 through any pipeline. For example, the owner can deliver the assets to the trust unit that owns the server 110, or through the grid. A specific network transmits assets such as electricity to an electric power institution having a storage server 110 or the like. The present invention is not limited to the person, the group, the unit, the organization, the organization, etc., and the transaction unit is a unit of the asset. For example, when the asset is gold, the transaction unit may be gram. When the asset is electric power, the trading unit may be watt/hour, etc., and the present invention is also not particularly limited.

In more detail, the vault server 110 can generate a blockchain transaction containing the address used in the blockchain network (referred to as the "seller address" in the present invention) and the number of transaction units added. (The number of transaction units added corresponds to the assets provided by the owner), and the generated blockchain transaction is sent to the blockchain network, so that the identification data used by the owner and the number of additional transaction units are added. In the blockchain that contains the asset smart contract, the number of trading units corresponding to the owned object is added to the asset smart contract. Since the process by which the custodial server 110 adds the number of transaction units corresponding to the owned object in the asset smart contract is the same as the process in which the custodial server 110 issues the asset smart contract to the blockchain, it is only briefly described.

The vault server 110 can also apply to the transaction server 150 for listing of assets.

The seller client 120 and the buyer client 130 are devices or devices having data input, operation and transmission capabilities, including but not limited to computers, mobile phones, tablets, watches, televisions, digital cameras, multimedia players, navigation devices, vehicles. Use computers, walkmans, computer dictionaries, e-book readers, TV game instruments, handheld game instruments, etc. In addition, the seller client 120 and/or the buyer client 130 may be connected to the transaction server 150 via a wired network such as Ethernet or a wireless network such as WiFi or Zigbee, but the invention is not limited thereto. In the present invention, the seller client 120 refers to a device or device operated by an object of possession of an asset (that is, a seller of an asset), and the buyer client 130 refers to a device or device operated by an object (ie, a buyer) who purchases an asset. .

The seller client 120 is responsible for obtaining the pending order clearing contract address corresponding to the pending order clearing smart contract generated by the transaction server 150, and placing a sell order in the pending order clearing smart contract according to the pending order clearing contract address. That is to say, the seller client 120 can obtain the pending order clearing smart contract from the blockchain according to the pending order clearing contract address, and can generate the information required to include the sell order (for example, the number of trading units, the selling price of each trading unit, and owning The blockchain transaction of the seller's address used by the object, etc., and the generated blockchain transaction is sent to the blockchain network, so that the required data of the sell order in the blockchain transaction is added to the billing clearing smart contract. In the blockchain, you can place a sell order in the pending order clearing smart contract. Among them, since the process in which the seller client 120 hangs the sell order in the pending order clearing smart contract is the same as the process in which the custodial server 110 issues the asset smart contract to the blockchain, it is only briefly described.

The buyer client 130 is responsible for obtaining the pending order clearing contract address corresponding to the pending order clearing smart contract generated by the trading server 150, and placing a buy order in the pending order clearing smart contract according to the pending order clearing contract address. Similar to the seller client 120, the buyer client 130 can obtain the pending order clearing smart contract from the blockchain according to the pending order clearing contract address, and can generate the information required to include the buy order (for example, the number of trading units, the buying of each trading unit) The blockchain transaction of the price, the buyer's address used by the buyer in the blockchain network, etc., and sends the generated blockchain transaction to the blockchain network, making the buy in the blockchain transaction The required information is added to the blockchain containing the pending order clearing smart contract, so that the buy order can be placed in the pending order clearing smart contract.

In some embodiments, the seller client 120 (or the buyer client 130) may obtain the agent address used by the seller (or buyer) agent in the blockchain network and may be in the pending order clearing smart contract. At the same time as placing the sell order (or paying the order), the agent's address obtained is set in the pending order clearing smart contract. That is, while generating a blockchain transaction containing the required information for the sell order (or the buy order), the agent address corresponding to the agent is also added to the generated blockchain transaction. It is worth mentioning that the agent address obtained by the seller client 120 and the buyer client 130 are not necessarily the same, that is, the seller and the buyer's agent do not need to be the same.

The transaction server 150 is responsible for generating the pending order clearing smart contract, and issuing the generated pending order clearing smart contract to the blockchain, and obtaining the corresponding one of the pending order clearing contract addresses. Similar to the custodial server 110, the transaction server 150 can pre-store the smart contract template and generate a pending order clearing smart contract based on the pre-stored smart contract template when a pending order clearing smart contract needs to be generated. Then, the transaction server 150 can generate a blockchain transaction including the generated pending order clearing smart contract, and send the generated blockchain transaction to the blockchain network, so that the pending order clearing smart contract is issued to the zone. In the blockchain, at the same time, the transaction server 150 can also obtain the pending order clearing contract address corresponding to the pending order clearing smart contract issued in the blockchain. The process in which the transaction server 150 issues the pending order clearing smart contract to the blockchain is the same as the process in which the custodial server 110 issues the asset smart contract to the blockchain, and thus is only briefly described.

The transaction server 150 is also responsible for receiving the asset contract address transmitted by the custodial server 110 and registering the received asset contract address in the generated pending order clearing smart contract. That is, the transaction server 150 can generate a blockchain transaction including the received asset contract address, and send the generated blockchain transaction to the blockchain network, so that the asset contract address in the blockchain transaction It is posted to the blockchain containing the pending order clearing smart contract to register the asset contract address in the pending order clearing smart contract. The process in which the transaction server 150 registers the asset contract address in the pending order clearing smart contract is the same as the process in which the custodial server 110 issues the asset smart contract to the blockchain, and thus is only briefly described.

The transaction server 150 is also responsible for pairing the buy and sell orders that are posted to the pending order clearing smart contract. In general, the transaction server 150 can execute the matching program periodically (such as every day, etc.) or at regular intervals (such as every thirty minutes or six hours, etc.) to search for matching purchase orders and sell orders, but the transaction servo The manner in which the pair 150 buys and sells the order is not limited to the above.

When the transaction server 150 successfully finds that a sell order and a buy order can be matched by multiple sell orders and multiple purchase orders in the pending order clearing smart contract, the pending order clearing smart contract can trigger the asset smart contract to perform asset trading and clearing. In more detail, the pending order clearing smart contract can obtain the corresponding asset smart contract based on the asset contract address contained in the same blockchain, and the number of trading units in the successfully matched buy order and the price of each trading unit and the buyer. The address, the seller's address in the successful matching sell order, and the like, as parameters, call the transaction clearing function included in the asset smart contract, thereby performing asset trading and clearing, so that the number of successfully paired trading units is transferred to the owner (seller) The buyer, and the possessing object can obtain the monetary value corresponding to the number of successfully matched trading units by the buyer. In the present invention, the proposed currency may be the legal currency used in the real world or the transaction currency used in the blockchain network, and the present invention is not particularly limited.

In some embodiments, the asset intelligence contract is a transaction and clearing of the number of successfully paired transaction units performed by the agent address set by the seller client 120 and/or the buyer client 130. In more detail, when the buyer hangs a buy order on the pending order clearing smart contract, the pending order clearing smart contract can take the buyer's address, the agent's address, the number of trading units, and the buying price of each trading unit in the buy order as parameters. Calling the asset agent function in the asset smart contract, whereby the currency value corresponding to the number of trading units in the buy order is transferred from the buyer account corresponding to the buyer address to the account corresponding to the agent address set by the buyer (in this case) In the invention, it is called "buyer agent account"). When the transaction server 150 successfully pairs the sell order and the buy order, the pending order clearing smart contract can successfully match the number of trading units and the price of each trading unit, the agent address in the buy order, the agent address in the sell order (or the seller address) The data is used as a parameter to call the asset transfer function in the asset smart contract, so that the monetary value corresponding to the number of successfully matched transaction units is transferred from the buyer agent account to the seller account corresponding to the seller address.

Among them, if the currency is the legal currency used in the real world, each function in the asset intelligence contract can transfer the legal currency value through the account network, that is, the function in the smart contract of the call account network to transfer the legal tender. Value, so that you can use the legal currency to trade assets through the blockchain.

Next, the operation system and method of the present invention will be explained with reference to the first embodiment, and the method of digitizing the quantifiable assets by smart contract and the "2B diagram" of the present invention will be described with reference to "2A". A flow chart of the method of trading assets with smart contracts. In the present embodiment, it is assumed that the asset is gold, but the invention is not limited thereto.

First, the vault server 110 can generate an asset intelligence contract (step 202), and publish the generated asset smart contract into the blockchain, and simultaneously obtain an asset contract address corresponding to the issued asset smart contract (step 206). ). In this embodiment, the asset smart contract generated by the deposit server 110 is an asset smart contract corresponding to gold.

After the custodial server 110 issues the asset intelligence contract to the blockchain and obtains the corresponding asset contract address, the custodial server 110 can apply to the transaction server 150 for listing the asset (step 210). In the present embodiment, that is, the deposit server 110 applies to the transaction server 150 for a gold listing.

Similarly, after the custodial server 110 issues the asset smart contract to the blockchain and obtains the corresponding asset contract address, the custodial server 110 can transmit the obtained asset contract address to the transaction server 150 (step 220).

Similarly, after the custodial server 110 issues the asset smart contract to the blockchain and obtains the corresponding asset contract address, the owner of the asset can hand over all or part of the assets owned by the custodian providing the custod server 110 or The organization, the custodian or the organization's personnel may operate the custodial server 110 to increase the number of transaction units corresponding to the seller's address used by the owner in accordance with the asset provided by the owner (step 236). In the present embodiment, assuming that the gold provided by the owner object has 100 grams, the custodial server 110 can add 100 transaction units to the seller address used by the owner in the asset intelligence contract.

After the transaction server 150 receives the asset contract address transmitted by the custodial server 110, the transaction server 150 may generate a pending order clearing smart contract (step 251), and issue the generated pending order clearing smart contract to the blockchain, and The pending order clearing contract address corresponding to the issued pending order clearing smart contract is obtained while the pending order clearing smart contract is issued (step 253). Next, the transaction server 150 can register the received asset contract address in the generated pending order clearing smart contract (step 255).

Thereafter, the seller client 120 operated by the owner object and the buyer client 130 operated by the buyer can obtain the pending order clearing smart contract address, and the clearing of the smart contract address is obtained by the transaction server 150 in the blockchain according to the obtained pending order clearing smart contract address. The pending order clearing smart contract, and placing the sell order and the buy order respectively in the obtained pending order clearing smart contract (step 260, step 270). In this embodiment, it is assumed that the number of trading units and the price included in the sell order are 100, 1250 (that is, the seller provides 100 grams of gold, and each gram sells 1250), and the number of trading units and the price included in the buy order are respectively 50, 1250 (that is, the buyer wants to buy 50 grams of gold at a price of 1250 per gram), wherein if the purchase order of the buyer client 130 also includes the agent address, the pending order clearing smart contract can be the agent in the sell order The address, the buyer's address, the number of trading units, and the transaction price are used as parameters to call the asset agent function in the asset smart contract, so that the total transaction amount of 62500 is transferred from the buyer account to the agent account.

After the seller client 120 hangs the sell order in the pending order clearing smart contract and the buyer client 130 hangs the buy order in the pending order clearing smart contract, the transaction server 150 can pair the sell order and the buy order of the pending order clearing smart contract (step 280). .

When the transaction server 150 successfully pairs the sell order and the buy order, the pending order clearing smart contract can trigger the asset smart contract to perform the transaction and clearing of the number of successful paired trading units (step 290). In this embodiment, since the purchase price in the buy order is the same as the sell price in the sell order, the transaction server 150 can successfully match the buy order and the sell order, and if the number of successfully traded units is 50, the asset smart contract The asset transfer function can deduct 50 trading units from the number of trading units corresponding to the seller's address in the asset smart contract, and increase the number of trading units corresponding to the buyer's address by 50 trading units. At the same time, the asset trading network can be 62500. The transaction amount is transferred from the agent account to the seller account. In this way, the transaction and liquidation of assets can be completed through the invention.

The operation system and method of the present invention will be described below with reference to the second embodiment, and please continue to refer to "2A" and "2B". In the present embodiment, it is assumed that the asset is power, but the invention is not limited thereto.

First, the vault server 110 can generate an asset intelligence contract (step 202), and publish the generated asset smart contract into the blockchain, and simultaneously obtain an asset contract address corresponding to the issued asset smart contract (step 206). ). In this embodiment, the asset smart contract generated by the deposit server 110 is an asset smart contract corresponding to the power.

After the custodial server 110 issues the asset intelligence contract to the blockchain and obtains the corresponding asset contract address, the custodial server 110 can apply to the transaction server 150 for listing the asset (step 210). In the present embodiment, that is, the deposit server 110 applies to the transaction server 150 for power listing.

Similarly, after the custodial server 110 issues the asset smart contract to the blockchain and obtains the corresponding asset contract address, the custodial server 110 can transmit the obtained asset contract address to the transaction server 150 (step 220).

After the custodial server 110 applies for the listing of the assets to the transaction server 150 (step 210), the owner object can install the solar panel to generate electric power (assets), and can deliver all or part of the generated electric power to the custodial server 110. The custodian or organization (step 232). In the present embodiment, it is assumed that the storage server 110 is provided by a power company, and the power generated by the possessing object can be supplied to the power company through the power grid.

After the owner of the power asset provides power to the power company, the power company can calculate the number of transaction units of the acquired power, and the custodial server 110 can calculate the increase in the seller address used by the owner in the issued asset smart contract. The number of transaction units (step 236).

After the transaction server 150 receives the asset contract address transmitted by the custodial server 110, the transaction server 150 may generate a pending order clearing smart contract (step 251), and issue the generated pending order clearing smart contract to the blockchain, and The pending order clearing contract address corresponding to the issued pending order clearing smart contract is obtained while the pending order clearing smart contract is issued (step 253). Next, the transaction server 150 can register the received asset contract address in the generated pending order clearing smart contract (step 255).

Thereafter, the seller client 120 operated by the owner object and the buyer client 130 operated by the buyer can obtain the pending order clearing smart contract address, and the clearing of the smart contract address is obtained by the transaction server 150 in the blockchain according to the obtained pending order clearing smart contract address. The pending order clearing smart contract, and placing the sell order and the buy order respectively in the obtained pending order clearing smart contract (step 260, step 270).

After the seller client 120 hangs the sell order in the pending order clearing smart contract and the buyer client 130 hangs the buy order in the pending order clearing smart contract, the transaction server 150 can pair the sell order and the buy order of the pending order clearing smart contract (step 280). .

When the transaction server 150 successfully pairs the sell order and the buy order, the pending order clearing smart contract will trigger the asset smart contract to perform the transaction and clearing of the number of successful paired trading units (step 290). In this embodiment, the asset transfer function in the asset intelligence contract may deduct the number of successfully paired transaction units for the seller address in the asset smart contract, and increase the number of successfully matched transaction units for the buyer address, and at the same time, according to the transaction. The unit’s price will be paired with the successful transaction amount from the buyer’s account to the seller’s account. Wherein, if the buyer is a power company, the asset transfer function in the asset intelligence contract may deduct the number of successfully matched transaction units from the seller address in the asset smart contract, and increase the seller after the buyer address increases the number of successful matching units. The power that can be used. In this way, the transaction and liquidation of assets can be completed through the invention.

In summary, it can be seen that the difference between the present invention and the prior art is that the storage server adds the number of transaction units corresponding to the owned object in the issued asset smart contract according to the asset of the owned object, and the transaction server is released. The pending asset clearing smart contract registers the asset contract address corresponding to the asset smart contract. After that, the trading server can pair the seller client to place the sell order in the pending order clearing smart contract with the buyer client to place the buy order of the pending order clearing smart contract. When the server successfully pairs the bills and the sell orders, the pending bill clearing smart contract triggers the trading and clearing technical means of the successful matching of the asset smart contract according to the asset contract address, and the technical means can solve the private transactions existing in the prior art.
