Description

  The present invention relates to a mining distributed management system and method.

  In recent years, not only transactions of goods such as yen and dollars but also business transactions using virtual currency such as electronic money have been performed. Further, a service using virtual currency called "Bitcoin (registered trademark)" which is open and distributed is proposed.

  In this bitcoin, a technology called “blockchain” is used for realization. First, in the transaction using bitcoin, the authenticity of the transaction information is secured using a hash function and a public key cryptosystem. Transaction information (hereinafter, referred to as “transaction”) of the virtual currency performed using the encryption technology is transmitted by broadcast to all terminals that use bitcoin. The transmitted transaction is verified for its authenticity by a terminal called a miner (miner), and when it is approved, it is put into a block and recorded in a ledger called a block chain. In Bitcoin transactions, the tampering of the transaction is prevented by having the miner perform a calculation process called mining and then adding blocks to the blockchain.

  Here, the last block of the block chain includes a plurality of transactions, the hash value of the block immediately before the last block of the block chain, and an appropriate value (“Nonce (nonce)”) that is determined in advance. ) Is stored. As mining, the miner performs a round robin search for a Nonce that generates a hash to be used for the next block from the hash value of the last block of the block chain and a transaction whose authenticity is to be guaranteed.

  At this time, an enormous amount of calculation is required for the miner to discover Nonce ahead of other miners. The extremely large amount of calculation is the basis for the authenticity of the contents of the blockchain. Such a method of spending a large amount of calculation to agree and authenticate each transaction on the network is called a proof of work. The proof of work is applied to show the authenticity of various information such as virtual currency.

  Various applications are being studied for this blockchain technology, and a similar cryptocurrency system (orthocoin) has been proposed based on the mechanism of bitcoin. Ortho coins include Litecoin, Dogecoin, Monacoin (registered trademark) and the like, and it is said that there are currently more than 500 cryptocurrency systems.

  In such a service that provides open and decentralized virtual currencies, the authenticity of the information (in the case of bitcoin, a transaction) described in the blockchain is calculated by the miner that supports the system. Depends on quantity.

  In other words, depending on the amount of calculation, an attack on the blockchain becomes possible. For example, it is known that if a malicious group or individual exceeds 50% or more of the total calculation amount, it will dominate over 50% or more of the mining speed of the entire network and illegal transactions will be possible (51%). attack).

  Therefore, in order to guarantee the authenticity of the proof of work, that is, to prevent tampering by an attacker, it is extremely difficult for the attacker to exceed the amount of calculation spent for the attack. A requirement is that the miner spends a very large amount of computation.

  Patent Literature 1 discloses a technique for increasing the degree of guarantee of authenticity of transaction information using such a block chain.

JP 2017-207860 A

  By the way, in the blockchain, a machine specification required for mining is required to be high with an increase in the calculation load on the proof-of-work described above. Along with this, the power consumption by mining has also increased, and depending on the region and scale, it often happens that it does not match the balance

  An object of the present invention is to provide a technique for solving such a problem.

The user terminal performs the mining process of the virtual currency based on an instruction from the management server,

<Details of Embodiment>
Hereinafter, a distributed management system for mining processing (hereinafter, referred to as “management system”) according to an embodiment of the present invention will be described with reference to the drawings.

<Overview>
The management system according to the embodiment of the present invention performs mining processing in a distributed manner by efficiently using surplus power of a power generation device using so-called renewable energy such as a solar power generation device.

  FIG. 1 is an image diagram showing an overall image of a management system 100 according to an embodiment of the present invention. It is to be noted that the illustrated overall image is an example, and other elements may be added.

  As illustrated in FIG. 1, the management system 100 includes a management server 1, a plurality of user terminals 2, and a solar power generation device 20 that supplies power to the user terminals 2.

  The management server 1 is connected to a plurality of user terminals 2 via a network, and builds a so-called client server model. Further, the management server 1 is also connected to a blockchain network 50. The management server 1 operates as a minor (miner) in the blockchain network 50.

  FIG. 2 is a diagram comparing a conventional power usage image (a) with a power usage image (b) of the management system 100 according to the present embodiment.

  As shown in FIG. 2A, the power generated by the photovoltaic power generation device 20 is divided into household consumption used by each user at home and surplus power not used.

  In addition, in the case of owning a device that generates so-called renewable energy such as solar power, a profit (incentive: right) related to CO2 reduction can be received according to the amount of power generated by the device. Such a reduction profit is a profit created based on the amount of CO2 emission reduction which can be reduced by introducing energy saving equipment and renewable energy power generation equipment.

  As shown in the figure, in the conventional case, surplus power is sold to, for example, a power company for each reduction profit (or separately from the reduction profit), and the user gets a price for the power sale.

  On the other hand, as shown in FIG. 2B, in the present embodiment, the surplus power is used in the user terminal 2 while managing it. The surplus power may include both the power used for the user terminal 2 and the power sold to a power company or the like.

  The user terminal 2 may have a function of managing the power generated by the solar power generation device 20. The management function performs the operation of the management server 1 and the user or the automatic allocation of the devices that use the generated power and the amount of power.

  The management server 1 remotely manages the user terminal 2, grasps and manages the state of the mining process, and pays a reward according to the result of the mining process. The reward is calculated by a predetermined formula based on the amount of virtual currency given in accordance with the mining process.

<Management data>
FIG. 3 is an example of a data table managed by the management server 1. The management server 1 manages the wallet ID associated with each user terminal 2, the state of the terminal, the mining rate, the total mined amount for the current month, and the amount of power generated by the power generation device supplied to the user terminal 2.

<Hardware configuration>
<Management server 1>
FIG. 4 is a diagram illustrating a hardware configuration of the management server 1. Note that the illustrated configuration is an example, and other configurations may be included.

  As illustrated, the management server 1 forms a part of a distributed management system by executing information processing together with a plurality of user terminals 2.

  The management server 1 includes at least a processor 10, a memory 11, a storage 12, a transmission / reception unit 13, an input / output unit 14, and the like, and these are electrically connected to each other through a bus 15.

  The processor 10 is an arithmetic device that controls the operation of the entire management server 1, controls transmission and reception of data between elements, and performs information processing and the like necessary for executing applications. For example, the processor 10 is a CPU (Central Processing Unit) and executes programs and the like stored in the storage 12 and expanded in the memory 11 to execute each information processing.

  The memory 11 includes a main storage configured by a volatile storage device such as a DRAM (Dynamic Random Access Memory) and an auxiliary storage configured by a non-volatile storage device such as a flash memory or an HDD (Hard Disc Drive). . The memory 11 is used as a work area or the like of the processor 10, and stores a basic input / output system (BIOS) executed when the management server 1 is started, various kinds of setting information, and the like.

  The storage 12 stores various programs such as an application program and an authentication program for a blockchain network. A database storing data used for each process may be built in the storage 22.

  The transmission / reception unit 13 connects the management server 1 to the network 10 and the blockchain network 20. The transmission / reception unit 13 may include a short-range communication interface of Bluetooth (registered trademark) and BLE (Bluetooth Low Energy).

  The input / output unit 14 is an information input device such as a keyboard and a mouse, and an output device such as a display.

  The bus 15 is commonly connected to the above elements, and transmits, for example, an address signal, a data signal, and various control signals.

<User terminal 2>
FIG. 5 is a diagram illustrating a hardware configuration of the user terminal 2. Note that the illustrated configuration is an example, and other configurations may be included.

  The user terminal 2 is managed by the management server 1 and forms a part of the distributed management system.

  The user terminal 2 includes at least a processor 20, a memory 21, a storage 22, a transmission / reception unit 23, an input / output unit 24, and the like, and these are electrically connected to each other via a bus 25.

  The processor 20 of the user terminal 2 is an arithmetic device that controls the overall operation of the user terminal 2, controls data transmission and reception between elements, and performs information processing and the like necessary for executing a mining application. For example, the processor 10 is a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit).

  As shown in FIG. 6, the management server 1 acquires information on the reduced profit 30 from each user terminal 20 and manages it (reduced profit pool). The acquired savings are stored using a blockchain network.

  As illustrated, the reduced profit pool may transmit information on a part or all of the reduced profit pool to another management server. That is, the acquired reduction profit may be sold.

  The blockchain network in the present embodiment may be a private network in which only a specific one can participate, or a public network.

  According to the above processing, the surplus power can be effectively used while distributing the load of the mining processing. In addition, by managing the reduction profit using the blockchain network, it is possible to improve security and tradeability.

  The embodiment described above is merely an example for facilitating the understanding of the present invention, and is not intended to limit and interpret the present invention. The present invention can be changed and improved without departing from the spirit thereof, and it goes without saying that the present invention includes equivalents thereof.
