Blockchain cloud mine ABC

1. There are few real baas that have been approved by the state. At present, the mainstream platforms are Tencent's tbaas, Jingdong Zhizhen chain jdchain, ant blockchain baas, Rongze's rbaas, network's Intelligent Cloud and Huawei's cloud BCS. Among them, the top four baas platforms are teams that have been researching and developing blockchain technology for several years, R & D capabilities are very strong.

2. What is mining
for example, bitcoin was invented by Zhongben Cong in 2009, and the total number of bitcoin was only 21 million. By participating in the proction of blocks and providing proof of work (POW), we can get the reward of bitcoin network. Mining is the process of packaging and confirming the transactions in the bitcoin system over a period of time, and then recording them on the block

if you need to know more about it, you can look at my account number; Let's discuss

what is moving bricks
when it comes to "moving bricks", you will think of migrant workers or various online jokes, but today we only discuss "moving bricks" in the blockchain market
to describe "moving bricks" in vernacular is to make profits by using the price difference between different exchanges. The same currency has different prices in different markets. Buy it in a cheaper place and sell it in a more expensive place. The middle price difference is your profit
for example, the price of bitcoin BTC is $4000 on exchange a and $4100 on exchange B. after a buys BTC, it can be sold to B and each one can earn $100. This process is called "moving bricks"

3. 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.

4. 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.

advantage: unlimited currency needs three confirmations for a transaction, and each confirmation takes 30 seconds, so the transaction confirmation speed is very fast. It is used in daily and common transactions, which is more practical

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

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

8. It is a good digital smart contract. It is a DAPP application of intelligent computing power based on Ethereum smart contract, which is developed by CMC of the United States as the core technology team, and is intended to build - 12032; It has the ability to quantify the value of scale, and has the ability to measure the value of scale; Evolutionary energy;, And it can promote the development of blockchain; Build a blockchain ecological application system based on the state of the art,
