Description

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

  In recent years, not only transactions of goods such as yen and dollars but also commercial transactions using virtual currencies such as electronic money have been performed. Further, a service using a virtual currency called “bitcoin (registered trademark)” has been proposed which is open and decentralized.

  This bitcoin uses a technology called "blockchain" for its implementation. First, in the transaction by Bitcoin, the authenticity of the transaction information is secured by using a hash function and a public key cryptosystem. Transaction information of virtual currency (hereinafter, referred to as "transaction") performed by using the cryptographic technique is broadcasted to all terminals that use Bitcoin. The authenticity of the transmitted transaction is verified by a terminal called a miner, and if approved, the transaction is put into a block and recorded in a ledger called a block chain. In bitcoin transactions, tampering with transactions is prevented by allowing miners to perform a calculation process called mining and then adding blocks to the blockchain.

  Here, in the last block of the block chain, a plurality of transactions, the hash value of the block immediately before the last block of the block chain, and an appropriate value with predetermined conditions (“Nonce”) That is,) and are stored. As a mining, the miner brute-force searches for a Nonce that generates a hash to be used for the next block from the hash value of the last block of this block chain and the transaction whose authenticity should be guaranteed.

  At this time, a huge amount of calculation is required for the miner to discover Nonce prior to other miners. This very large amount of calculation is the basis of the authenticity of the contents of the blockchain. A method that consumes a large amount of calculation to agree and authenticate each transaction in this way is called proof of work. Proof of Work is applied to show the authenticity of various information such as virtual currency.

  Various applications have been studied for this blockchain technology, and a similar cryptocurrency system (orthocoin) has been proposed based on the mechanism of bitcoin. As the ortho coins, there are light coins, doge coins, mona coins (registered trademark) and the like, and it is said that there are currently more than 500 cryptocurrency systems.

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

  In other words, depending on the amount of calculation, it is possible to attack the blockchain. For example, it is known that when a malicious group or individual exceeds 50% or more of the total calculation amount, it controls 50% or more of the mining speed of the entire network, which enables illegal transactions (51%). attack).

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

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

  By the way, in the blockchain, the machine specifications required for mining are required to be high as the calculation load for the proof of work increases. Along with this, the amount of power consumed by mining has also increased, and depending on the region and scale, it often happens that the balance is not met.

  The present invention aims to provide a technique for solving such a problem.

<Outline>
A management system according to an embodiment of the present invention efficiently uses surplus power of a power generation device such as a solar power generation device by so-called renewable energy, and performs mining processing in a distributed manner.

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

  As shown 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 the block chain network 50. The management server 1 operates as a miner (miner) in the block chain network 50.

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

  Further, when a device that generates so-called renewable energy such as solar power generation is owned, 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 generated based on the CO2 emission reduction amount reduced by introducing the energy saving facility and the renewable energy power generation facility.

  As shown in the figure, in the conventional case, surplus power is sold to a power company or the like for each reduction profit (or separately from the reduction profit), and the user obtains a consideration 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 being managed. The surplus power may include both the power used for the user terminal 2 and the power sold to the power company or the like.

  The user terminal 2 may have a function of managing the electric power generated by the solar power generation device 20. The management function allocates a device using the generated electric power and the amount of electric power by an operation from the management server 1 or a user or automatically.

  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 according to a predetermined calculation formula based on the amount of virtual currency given according to the mining process.
