108 blockchain mining treasure
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
e to the decentralized accounting method, open and traceable data, intelligent contract to ensure trusted transactions and other characteristics of the technology itself, blockchain is a perfect match for various applications in finance, logistics and other fields. However, e to the market's low acceptance of blockchain technology and the incomplete development and basic conditions of related instries, the technology has not been widely used in related instries. However, some instries with concentrated indivial users are ahead. The game instry has a huge demand for users to buy and sell game equipment, and the game equipment belongs to digital assets, Transaction has financial attributes, and it is also an ideal scenario for the application of blockchain technology< br />
looking at the current domestic blockchain games, dozens of them have appeared in recent half a year, but most of them are pet nurturing games with pictures and words to explain the rules, which have little entertainment value. Some Internet reports also mentioned that it only takes about five days to a blockchain pet game. It can be imagined that the blockchain game copied by such a simple method is difficult to be well designed and even less attractive to players. There are also other types of blockchain games, such as real estate games. Users can use tokens in game scenes to purchase land, services and procts in the virtual world, obtain property rights, and build buildings on their own land. But this kind of game in the country to do more influential is rare< br />
the combination of blockchain and games is supposed to improve the convenience and effectiveness of game digital asset management with blockchain technology, so as to enhance the overall use experience of players. However, the current domestic mainstream practice is to find suitable landing applications for blockchain technology, and reluctantly implant blockchain technology with simple and crude games, This practice of "block chain for the sake of blockchain" undoubtedly deviates from the design intention of the game itself from the source, which is the pain point of the domestic blockchain game instry< br />
in fact, many popular games on the market do not have very complex design ideas, as long as the extremely simple operation can help white-collar workers relieve the pressure of intense work. Simple but not hasty. Users play simple games, designers often spend more time in the game development stage. For example, an Auckland miner game, which is popular in New Zealand recently, uses the mutual help between human beings and elves in the magic world to connect simple story clues, and takes the beautiful natural scenery of Auckland island under different geographical environments, such as forests, caves and glaciers, as the basis of game art design. Although the play method is simple, the picture is beautiful. Players can "hire" miners to dig gold coins with the game token. Of course, the gold mining capacity will vary with the miner's level, and different mining tools will also affect the gold mining effect. The game also has a "steal" gold coin mechanism, that is, players can invite friends to participate in the game, and in the case of friends "not in the mine", they can take the opportunity to steal the other party's gold coins, so as to quickly increase their wealth. Of course, "steal" also have a way, as long as the player requisition "guard dog" guard "mine", can avoid the loss of theft. This part of the game is very similar to the popular "stealing vegetables" game in recent years. Although it is not innovative, it caters to the interactive nature of social media, which is one of the reasons why the game can rapidly expand the overseas Chinese circle. For game users, this kind of game does not need to be thought-provoking, and they do not need to concentrate on it. Players can "steal" people's gold coins while chatting with others. I believe this kind of "secret joy" is also a small sense of achievement for many players to play this game< br />
of course, as a blockchain game, Auckland miners also provide game profit channels for players, that is, while playing the game, players can earn tokens by mining, and get appropriate returns while paying the time cost. This is also one of the important reasons why many blockchain games can attract a large number of fans< br />
the success factors of Auckland miner game are briefly analyzed, including simple game logic, interactive social attribute, token profit mechanism, and finally the art design of the game itself. The original intention of players to participate in the game is to get entertainment and relaxation from the game. Therefore, pleasing art design and game interface are also the key to the success of any game. At this point, Auckland miners game takes the beautiful natural environment of New Zealand as the background of the story, and has natural advantages, which will also help this game to become popular quickly.
generally speaking, bitcoin and cryptocurrency tokens provide you with more control. You effectively cut the middleman between you and your money. No bank can decide how long a transaction will take and how much it will cost. You can also control where funds are stored and how they are accessed. Of course, control brings corresponding responsibilities
2. Affordability
since the middleman is not in the picture, you can save some transfer fees. Moving bitcoin from one wallet to another costs a negligible amount of money. It is cheaper for businesses to accept bitcoin payment than credit card payment
3. Speed
in addition to saving international transfer fees, you can also enjoy higher transaction speed. What does it take your bank a few days to do? Bitcoin can do it in a few minutes
4. Convenient
with bitcoin, online payment is easier and faster. If you want to donate or pay for something that will not be delivered, you do not need to disclose any personal details. Just send bitcoin to their wallet address
5. Security
it is safer for businesses to accept bitcoin than fiat money. When businesses accept credit card payments, they risk fraud and reverse payments. Bitcoin payment is irreversible, so there is no risk of reversal
6. Privacy
one of the main advantages of using bitcoin is that it provides privacy and relative anonymity. You don't need to provide any personal details to access the bitcoin wallet. All you need is a device to store it - even a piece of paper. Bitcoin transactions are only linked to your wallet address
7. Reliability
bitcoin network is essentially a point-to-point payment system. This allows you and you to remit money to anyone who participates in the party. You don't have to rely on the bank to do the work to make the transaction effective. In Ethernet, the risk of payment loss is small, which eventually makes it a more reliable way of payment
8. Investing in
bitcoin wasn't worth a lot of money ten years ago. Let's see where it has been since 2009. From a few dollars in December 2017 to nearly $20000. At the time of writing, it is now stable at around $6000. As more and more people adopt bitcoin, bitcoin will not be everywhere. Investing in it may be risky, but it's absolutely profitable.
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
