What's the meaning of mining disaster

1. The so-called mining, in fact, refers to the use of computer operations, in the virtual world to obtain virtual currency, that is, the process of bitcoin
Mining requires powerful computing power of computers. In the early days, it mainly relied on CPU, but now it mainly relies on mining machines integrated with a large number of graphics cards
the graphics card in the miner works continuously for 24 hours, and the heat dissipation environment is bad, so the long service life is shortened rapidly
the obsolete graphics card on the miner is the mine card. It is not recommended to choose this kind of graphics card, so it is very easy to have problems.

2. 1. What does mining mean
ancient mining can be traced back to the selection of stone materials in the stone age. Later, with the rise of the metallurgical instry, mining, mineral processing technology has graally developed. This paper introces the ancient Chinese open-pit mining, underground mining, roadway support, rock fragmentation, roadway ventilation, lighting, drainage, transportation, mineral processing and other aspects< There are many surface outcrops, slope deposits or resial deposits in open-pit mining of various metal veins or orebodies, so open-pit mining has become an important mining method in ancient times. Open pit mining can be divided into excavation method and reclamation method
2. Mining is the synonym of accumulated income for activities in bitcoin

mining is brought out by the recent popularity of bitcoin. As a virtual currency, bitcoin can be exchanged for real currency. One of the ways to get bitcoin on the Internet is to participate in related activities every day. These activities, like mining in online games, need to slowly accumulate wealth in exchange for bitcoin.

Mine card refers to the graphics card used by bitcoin mining machine, mostly amd graphics card

mine disaster refers to the decline in the price of bitcoin and the sale of second-hand mine cards

bitcoin mining machine graphics card long-term high load operation, graphics card service life will be reced accordingly, so the price will be cheaper

extended data:

bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

Mining bitcoin is also called mining. Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique

in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods

shortcomings

first, the vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities

Second, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed

Thirdly, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading

Fourthly, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless

5. Most businessmen and speculators are always interested in things that can be turned into money immediately. Bitcoin is one of them. The specialization of ASIC chips leads to the market separation between bitcoin mining and other Shanzhai coin mining
when the vast majority of video card mining machines and CPU mining machines are in a mine disaster, bitcoin mining with ASIC mining machines will not be affected. As the first big man in the virtual currency circle, bitcoin has become a deep-rooted belief in the coin circle. The total number of 21 million bitcoins also determines the transaction type and value-added of bitcoin
although bitcoin has begun to be recognized by most people, it has not really replaced the world's currency to fulfill its original intention, but it has become a collection beyond gold. The inflation of money, the rection of the total amount of mining and the increasing difficulty of mining all determine its future market prospects. The value-added has been firmly established, so people will rush to dig for mines, Because the bitcoin is actually worth more than gold

Mine disaster refers to the accident in the process of mining, which usually causes great risk of casualties. At least thousands of people die in mine disaster every year in the world. The common mine disasters include: gas explosion, coal st explosion, gas outburst, water leakage accident, mine fire, roof collapse, etc. In 2003, China proced about 35% of the world's coal, but accounted for about 80% of the deaths in coal mine accidents

China is a big coal procing country, a country heavily dependent on coal energy, and also a country with mining disasters. The main causes of the mine disaster are illegal mining, proction errors, equipment aging and faults. Each mine accident shows that solving these problems needs the unified coordination of all levels of departments. Only by constantly strengthening the management of mining, can the occurrence of mine accidents be effectively reced

It is a serious disaster in coal mine proction that gas is mixed with air, oxidizes rapidly at high temperature and proces shock wave. In 1675, a large-scale gas explosion occurred in Mostyn coal mine in England. Since then, major gas or gas and coal st explosion accidents have occurred many times in major coal mining countries. On April 26, 1942, a gas and coal st explosion occurred in Benxi Coal Mine, China, which was occupied by Japan. 1528 people died and 268 people were injured on the spot. It was the largest coal mine explosion in the world. With the development of coal mine proction technology and the improvement of gas control measures, such accidents have been graally reced

the main fire sources of gas explosion in China's coal mines are electric spark and blasting, and the main place of occurrence is mining face. The instantaneous temperature of coal mine gas explosion can reach 1850 ~ 2650 ℃, and the pressure can reach 9 times of the initial pressure. The gas near the explosion source impacts outward at a speed of several hundred meters per second, causing casualties and damage to the roadway and equipment. After the explosion, the oxygen concentration decreases and a large amount of CO2 and Co are generated, which may cause asphyxiation and poisoning

7. Atom chain (ATOS) is a financial processing scheme based on the decentralization of blockchain. Its policy is to build a free and smooth system of goods in a global scale through blockchain and distributed ledger technology. This system allows each user to stop international financial business freely. Atomic link consists of five layers: data layer, collection layer, consensus layer, contract layer and application layer. The data layer uses the distributed ledger technology to control the publication, payment and communication of the goods; The collection layer accepts peer-to-peer collection realized by P2P collection and negotiation; The consensus layer is based on POD and BFT consensus algorithm; The contract layer accepts the genesis contract and the multi talk smart contract, stops the publication and processing of the proct spring, optimizes the fake machine, supports Turing in good condition, and adopts the self-examination mechanism to prevent the deadlock state in Turing in good condition; The application layer is friendly to multiple types of terminals, so developers can easily develop applications based on atomic chain. Through the decentralization of the autonomy situation, build a diversified financial smooth collection, promote the activity, safety and universality of the spring. Atos as a win-win ecological goods spring unit, the policy is to become a universal goods spring of global international business. Atomic chain as an open system, users can develop all kinds of independent DAPP based on atomic chain API, and establish personalized application scenarios

atomic chain technology will have a new breakthrough. Bitcoin is difficult to become a country's foreign exchange reserve because it has more than 51% of the computing power in the oligopoly pool and has the risk of beatings by bilit. The more decentralized pod algorithm of atom link, the so-called pod algorithm, is the first algorithm named by our atomic chain. This algorithm is implemented on iota (top 10 encryption spring), but it is not officially named. It is the abbreviation of power of device. Business 0 handling charge, but before business need to help the whole collection processing two business. In this way, the more people we use and the more computing power we have, the faster the transfer will be. Every user is a node, so our TPS has no upper limit, far more than bitcoin only needs 7tps, Ethereum only needs 15tps, and EOS million TPS... And there is no handling charge, so there is no need to mine. There is no ore pool. Why should there be a ore pool to control 51% of the total network computing power? It's always highly decentralized. Accepting DAG (directed acyclic graph) can process a large amount of data on the chain in parallel, and can perfectly deal with the problem of slow speed of bitcoin business
