Description

Virtual currency management system and method

The present invention relates to a virtual currency management system and method for managing virtual currency transactions.

In recent years, virtual currency is increasingly used instead of legal currency. In transactions such as new issuance and delivery of virtual currency, the technology of the hash function and the public key cryptosystem is used to ensure the reliability and security of the attachment information (transaction) and prevent the attachment information from being falsified.

{Specifically, the transaction of the virtual currency generated by the encryption of the public key cryptosystem is broadcast (broadcast) to all the computers responsible for the management of the virtual currency. This transaction is verified by an information terminal called a miner (minor), and if approved, is bundled into a block, and the block is broadcast and added to a block chain.

A block includes a plurality of transactions. When the block is generated, a value is brute-force substituted into a predetermined hash function, and a return value (hash value) of the hash function is determined in advance. When the determined predetermined condition (difficulty) is satisfied, the substitution value is included in the block information as a nonce.

処理 The process of searching for nonces in this way is called mining, and it requires a huge amount of computation before finding a nice one. The method for ensuring safety and reliability in this way is called a proof of work (PoW).

One important factor in such a virtual currency management system is how to secure as many information terminals as minors. From such a viewpoint, a virtual currency management system and method disclosed in Patent Literature 1 in which an information terminal of a user browsing a website calculates a hash value is known.

A plurality of information terminals (in the same document, “user terminals 30A, 30B, 30C”) that browse a site (in the same document, “Web sites 20A, 20B, 20C”), the web server and the plurality of information terminals, A management server (in the document, “virtual currency management device 10”) that is configured to be communicable and manages transactions of virtual currency.

The management server is connected to a peer-to-peer network that manages transactions of one or more types of virtual currencies defined as management targets, and instructs the information terminal to calculate a hash value for mining (search for nonce), A calculation result from the information terminal is received, a block is generated using the received calculation result, and the block is broadcast to a decentralized network of the virtual currency subject to the mining and added to a block chain.

According to the virtual currency management system having such a configuration, since the information terminal browsing the website can unconsciously participate in mining as a minor, it is easy to secure the minor information terminal, while the management server is Such as receiving a processing request for mining for virtual currency transactions, determining load distribution for determining which information terminal should search for a nonce with which information terminal for the mining, and block generation. Since various processes are performed collectively, there is a problem that the load is concentrated and the redundancy is lacking.

FIG. 1 is an explanatory diagram illustrating the configuration of a virtual currency management system to which the present invention has been applied. The virtual currency management system includes a plurality of information terminals 10 that use a user, a service providing server that can communicate with each information terminal 10 via a global network N such as the Internet, and that provides a service to the information terminal 10. 20, an information processing server 30 capable of communicating with each of the information terminals 10 and the service providing server 20 via the network N and performing various types of information processing, and capable of communicating with the information processing server 30 via the network N And a management server 40 that receives a request for a mining process for trading a virtual currency and performs at least a part of the management of the virtual currency.

The information terminal 10 is a personal computer, tablet, or smartphone used by the user. The user performs user registration with the service providing server 20 by using the information terminal 10 or the like, and enjoys the service from the service providing server 20 by installing a dedicated application, or an existing user already installed in the initial state. The provision of the service from the service providing server 20 is enjoyed by the web browser.

The service providing server 20 provides a service via the network N to the information terminal 10 of the user who has registered the user and stored his / her information (user information). Various types of services can be envisaged. For example, a service that provides the information terminal 10 with a game play environment and a service that provides the information terminal 10 with a website browsing environment can be considered. When the service is to provide a game environment, the user plays the game using the dedicated application installed on the information terminal 10 or an existing web browser.

(4) The management server 40 selects one or more types of virtual currencies to be managed as target virtual currencies. The management server 40 is connected to a distributed network (not shown) that is a p2p network formed for managing each target virtual currency. When the management server 40 receives a request for processing including mining for a new issue or transfer of the target virtual currency from the distributed network of the target virtual currency, the management server 40 calculates a hash value for the mining during the processing. The information processing server 30 is requested to execute the calculation processing including the calculation processing.

仮想 In the distributed network, the management of the virtual currency is autonomously and decentralized by a plurality of computers (distributed management computers). All the distributed management computers in the distributed network for one virtual currency hold the same blockchain information. Incidentally, it is not necessary for all information terminals accessing the distributed network at the time of trading virtual currencies to hold blockchain information. In other words, information terminals other than the decentralized management computer also access this decentralized network and trade virtual currencies managed by the decentralized network.

(4) The information processing server 30 holds user information on the same user registered with the service providing server 20. Then, the information processing server 30 selects information terminals 10 of one or a plurality of users who are enjoying the service (for example, playing a game) among the registered users, as the selection terminals. The calculation process is executed using the resources of the selection terminal 10, and the calculation result is transmitted to the management server 40.

In this manner, a nonce that satisfies the difficulty is searched for using the surplus processing capacity (resources) of one or more information terminals 10. When a nonce is discovered by such an exchange between the information terminal 10 and the information processing server 30 or an exchange between the information processing server 30 and the management server 40, the management server 40 transmits the nonce information and a plurality of transactions. A block including information is generated, and the block is broadcast to a decentralized network that manages the virtual currency to be mined, and the block is added to the block chain of the virtual currency.

When the generated block is successfully added to the block chain, the information of the success is notified as a mining result to the management server 40 via the distributed network, and a mining reward which is a reward for finding a nonce by mining is generated. Is paid to the management server 40 in virtual currency managed by the distributed network.

The management server 40 transmits the mining result and the information on the mining reward to the information processing server 30. The information processing server 30 that has received the mining result and the information on the mining reward derives the contribution of the information terminal 10 of one or a plurality of users who participated in one or a plurality of mining. The derived information on the degree of contribution is passed from the information processing server 30 to the service providing server 20 via the network N.

{Circle around (5)} Then, the service providing server 20 provides a resource provision reward according to the contribution degree to the information terminal 10 of one or a plurality of users according to the contribution degree. The reward may be a virtual currency, or may be an additional service that is advantageous for enjoying the service, such as a game item that is a provided service or a currency in the game.

In this way, the reward for mining is distributed to the information terminals 10 participating in the mining, and the reward is also distributed to the service providing server 20, the information processing server 30, and the management server 40 at a predetermined rate. . The form of the reward may be a virtual currency or cash. If the reward is cash, a predetermined amount of legal currency is transferred to the designated account.

FIG. 6 is a flowchart showing a processing procedure for adding / deleting a resource providing user. When the user performs a service start operation (for example, a website access operation or a game start operation) with the information terminal 10 (S101), the service receiving unit 11a of the information terminal 10 sets the user ID or password of the user. Is requested to the service providing server 20 for user authentication of the user (S102).

The user authentication unit 21a of the service providing server 20 performs user authentication based on the user authentication request, and performs the user authentication from the information terminal 10 to the information processing server 30 when the user authentication is successful. The information terminal 10 is notified (S103). In response to the notification from the service providing server 20, the service receiving unit 11a of the information terminal 10 makes a user authentication request to the information processing server 30 using the user ID and password (S104).

The information processing server 30 receives the user authentication request from the information terminal 10 by the user authentication unit 31a (S105). If the user authentication is successful, the user of the information terminal 10 has the surplus processing capacity. A resource providing user adding process for adding a resource providing user to be provided with a resource is executed (S106).

(4) The processing unit 31 is provided with a resource providing user adding unit 31b for executing the resource providing user adding process. Further, information of the added resource providing user is added to a list of lists stored in the resource providing user storage unit 32b which is a storage area secured in the storage device 32.

Next, the service providing unit 21b of the service providing server 20 starts providing the service (S107).

On the other hand, while the service is being provided, when the user who is a resource providing user performs an end operation using his / her own information terminal 10 (S108), the service providing server 20 is notified to that effect. The service providing server 20 that has received the notification also notifies the information processing server 30 of the content (S109).

When the information processing server 30 receives the notification, the information processing server 30 deletes the user from the list of the resource providing users stored in the resource providing user storage unit 32b so that the user who performed the ending operation is not a resource providing user. A resource providing user deletion process is performed (S110). The processing unit 31 is provided with a resource providing user deleting unit 31c for performing the resource providing user deleting process.

Then, the service providing unit 21b of the service providing server 20 finishes providing the service to the information terminal 10 of the user who performed the ending operation (S111).

FIG. 7 is a flowchart showing the processing procedure of mining. The management server 40 arbitrarily selects an unprocessed one from among one or a plurality of processing requests received by the processing request receiving unit 41b and stored in the processing request storage unit 42a, and performs mining during the selected processing request. A calculation instruction including an enormous amount of hash value calculation for the information processing server 30 is executed (S201). The processing unit 41 is provided with a calculation instruction section 41c for executing the calculation instruction processing.

The information processing server 30 executes a calculation instruction receiving process of receiving a calculation instruction notified from the management server 40 via the network N (S202). The processing unit 31 is provided with a calculation instruction receiving unit 31d for executing the calculation instruction receiving process. In the calculation instruction receiving process, the received calculation instruction is stored in the calculation instruction storage unit 32c secured as a storage area in the storage device 32.

Subsequently, the information processing server 30 selects the information terminal 10 of one resource providing user who processes the received calculation instruction as a selection terminal, or the information terminal 10 of a plurality of resource providing users who processes the calculation instruction. Is selected as a selection terminal, and what kind of processing is distributed to the plurality of selection terminals 10 is determined, so that the target and content of the execution instruction are determined. An execution instruction process is performed on the selected terminal via the network N (S203).

(4) The processing unit 31 is provided with an execution instruction unit 31e for executing the execution instruction processing. In the execution instruction process, the execution instruction notified to each selection terminal 10 is stored in the execution instruction storage unit 32d secured as a storage area in the storage device 32.

Incidentally, the means for determining the target and content of the execution instruction in the execution instruction processing will be described later.

According to the above-described contents of the execution instruction processing, the user who becomes the selection terminal 10 is limited to the resource providing user who is enjoying the service, so that the cooperation of providing the resource from the information terminal 10 is not possible. Easy to obtain.

When receiving the execution instruction from the information processing server 30, the service receiving unit 11a of each of the selection terminals 10 calculates a hash value for searching for a nonce based on the content of the execution instruction (S204). The execution result is transmitted to the information processing server 30 via the network N (S205). By the way, when transmitting the execution result from the selection terminal 10, it is verified whether or not the nonce search has succeeded (primary verification), and the execution result is transmitted to the information processing server 30 only when the search is successful. Note that the primary verification may be omitted, and the entire calculation result of the hash value may be transmitted as the execution result.

The information processing server 30 executes an execution result receiving process for receiving an execution result from each of the selection terminals 10 (S206). The processing unit 31 is provided with an execution result receiving unit 31f for executing the execution result receiving process. In the execution result receiving process, the execution result from each selection terminal 10 is stored in the execution result storage unit 32e secured as a storage area in the storage device 32.

Incidentally, the execution result information is stored in the execution result storage unit 32a in a state that can be distinguished for each user. More specifically, the execution result information sequentially stored in the execution result storage unit 32e includes identification information (for example, a user ID) capable of distinguishing each user. For this reason, it is possible to later confirm which user's information terminal 10 the execution result is from. In this sense, the information stored in the execution result storage unit 32a is also sequentially updated. Part of.

Subsequently, the information processing server 30 verifies whether or not the nonce has been successfully searched for the execution result received from each of the selection terminals 10 (secondary verification). A calculation result, which is a result of the calculation instruction, is derived, and a calculation result transmission process of transmitting the calculation result to the management server 30 via the network N is executed (S207). The processing unit 31 is provided with a calculation result transmission unit 31g for executing the calculation result transmission processing. Note that the secondary verification can be omitted.

(4) The management server 40 executes a calculation result receiving process of receiving a calculation result from the information processing server 30 (S208). The processing unit 41 is provided with a calculation result receiving unit 41d that executes the calculation result receiving process. In the calculation result receiving process, the received calculation result is stored in the calculation result storage unit 42b secured as a storage area in the storage device 42.

Next, the management server 30 verifies the success or failure of the nonce search with respect to the received calculation result (tertiary verification), and executes a block generation process of generating a block using the searched nonce (S209). The processing unit 41 is provided with a block generation unit 41e that executes the block generation processing. When the verification of the success of the nonce search in the selection terminal 10 and the information processing server 30 is omitted, the verification in the management server 30 is a primary verification, and any of the selection terminal 10 and the information processing server 30 If the verification on one side is omitted, the verification on the management server 30 is a secondary verification.

Next, the management server 30 executes a broadcast process of broadcasting the generated block to a distributed network that manages the virtual currency to be mined for generating the block (S210). The processing unit 41 is provided with a broadcast unit 41f for executing the broadcast processing.

The information of the broadcasted block is received by each distributed management computer in the distributed network and added to the block chain, and it is recognized that the mining is successful.

Note that a storage area for storing the information of the block chain may be secured in a part of the storage device 42 of the management server 30 as a break chain storage unit 42f, and the management server 30 may function as a distributed management computer.

Incidentally, in deciding the target and content of the execution instruction in the execution instruction processing (deciding what kind of processing to be performed by the resource providing user selection terminal 10), each resource providing user stored in the execution result storage unit 32e is determined. Some or all past execution results of the selection terminal 10 are referred to.

(4) The period for referring to the execution result may be appropriately determined. For example, for one user, the provision of the service is started, and after the information terminal 10 of the user is selected as the selection terminal, the information of the user is limited to a period until the provision of the service is completed once. The execution result of the terminal 10 may be referred to. This makes it easy for the user to change the information terminal 10 every day and receive service.

Alternatively, the specification or type of the user's information terminal 10 may be estimated based on one or more execution results received, and the estimation result may be used to determine the target and content of subsequent execution instructions. Furthermore, the target and content of the execution instruction may be determined with reference to the user information stored in the user storage unit 32a. The user information includes the user's personal information, service provision status, specifications of the information terminal 10 used, and the like.

FIG. 8 is a flowchart showing a processing procedure of reward distribution. When the mining is successful (addition of the block to the block chain is successful), the management server 40 executes a mining result acquisition process for acquiring a mining result as a result from the distributed network N (S301).
