Blockchain cloud mine

1.

In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining

the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig

another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

extended data

currency characteristics of bitcoin

1, decentralized

bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom

2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3, exclusive ownership

controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself

4, low transaction cost

bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution

5, no hidden cost

as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6, cross platform mining

users can explore the computing power of different hardware on many platforms

2. Mining is a way of exchanging time for space and buying currency at fixed cost. The growth of computing power, the rise and fall of currency price and the update of equipment will be in a dynamic balance. As long as you are optimistic about the blockchain and feel that you don't have the ability to stir up money with high price and low price, investment and mining will be a good choice for blockchain investment. Can contact NB cloud mining, mining agent operation, more professional, every day there are benefits.

3. It refers to the person or machine that tries to create a block and add it to the blockchain (the word also refers to the software that does it). When a new valid block is created, the bitcoin protocol automatically distributes 50 (now 25) new bitcoins to the corresponding miners as a reward for their work. This is also the basis of bitcoin's existence.

4. With the rapid development of digital asset exchange market, its new upsurge is coming! And the development of digital asset trading website is mixed, for investors, it is easy to make profits if they retreat, so how to choose a safe trading website to let the majority of users rack their brains, how to do the trading website to have its own advantages
Development: This article is developed by yuanzhongrui editor / exchange to see the name
Security: digital assets are stored in hot and cold wallets, and multiple authentication ensures the account security
stable: user data is backed up multiple times around the world, and can be recovered immediately in case of failure
specification: the 100% digital currency margin system can timely respond to the withdrawal needs of customers
Service: provide customer service staff to help you solve problems at any time
Technology: continuously update and iterate the system according to the user's needs and opinions on the website and the market
in addition, the platform also needs to have an intelligent data analysis and trading system to provide users with a variety of trading strategies and results analysis, so as to make the transaction more flexible and convenient.

1 Division of mining units of ore deposits generally, ore deposits occupy a large area and have abundant reserves. In order to develop in a planned way, the ore deposits are often divided into several parts (mining units) from large to small according to the occurrence conditions of ore bodies, and are classified into corresponding mining enterprises (proction units) for mining

generally, the distribution range of ore deposits is called mining area, which is usually classified as a Mining Bureau (or company). All deposits in the same geological structure and of the same origin are called ore fields (coal mines are called coalfields). If the mine field is large in scale, it can be divided into several parts, each part is mined by a mine (pit mouth), which is called mine field (Figure 12-1). The boundary of mine field can be artificial boundary or natural boundary. During mining, the mine field must be divided into smaller parts. For inclined seam, the seam is usually divided into several long sections parallel to the strike according to a certain elevation along its inclined direction, which is called stage (or middle section), and the upper and lower interface is called horizontal, such as 0m level and - 50m level (Fig. 12-2). When the stage is small, the mining can be carried out at one time along the whole stage; If the stage area is large, it should be further divided into n mining areas, each mining area along the inclined layout of n mining faces, called section

Fig. 12-8 schematic diagram of roof failure zoning

(according to Beijing Academy of Coal Sciences, 1985)

a-irregular caving; B - rule falling; C-serious fracture; D-general cracking; E - tiny crack; F - caving zone; G-fracture zone; H-overall moving zone; I-fracture zone

1) caving zone: the area where the direct roof splits into pieces and collapses downward. It can be divided into irregular caving section and regular caving section. The rocks in this area are broken and expanded, accumulated and permeable, which can form a channel for the upper groundwater or surface water to pour downward, causing water inrush. Generally, this area is not allowed to develop into the upper strong aquifer or surface water

2) fracture zone: a large number of mining fractures with cut and separated layers appear above the caving zone. The zone can be divided into three sections: serious fracture section, general fracture section and micro fracture section. When the zone reaches the supply water source, the mine water inflow will increase sharply, even cause water inrush

3) overall movement zone of rock stratum: the zone is located above the fracture zone, which is generally characterized by the overall bending deformation or shear displacement of the stratum, or the overall bending and falling in the zone. Generally, there is no fracture and it does not form a water filling channel

6. 7、 The distribution of quick mining is different every day. It mainly depends on the blockchain. How to allocate it depends on the local profitability today?

7. I'm not sure about other things, but I heard that IPFs, a magic calculation of fire and thunder, is pretty good.
