What do you mean by mining at home
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.
Mining: that is, bitcoin mining, is a process of using computer hardware to calculate the location of bitcoin and obtain it
3, users use personal computer to download software, and then run specific algorithms. After communicating with remote server, they can get corresponding bitcoin, which is one of the ways to get bitcoin. Ordinary graphics cards don't need to try, and electricity charges are not enough. Master Lu has bitcoin test, which can see how long it takes for your computer to dig a bitcoin
Mining means that users download software from personal computers and then run specific algorithms to get corresponding bitcoin after communicating with remote servers
bitcoin is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods
bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware, and the miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by the miners, so the competition for mining is very fierce
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

extended materials:
the founder of bitcoin:
on November 1, 2008, a person who called himself Satoshi Nakamoto posted a research statement on a secret cryptography review group, stating his new idea of e-money - bitcoin came out and the first transaction of bitcoin was completed
bitcoin has got rid of the constraints of third-party organizations with the help of Internet, which Nakamoto calls "regional chain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money
trading is also extended on this network. The computer running this software can solve the problem of irreversible code, which contains several trading data
the first "miner" to deal with the problem will be rewarded with 50 bitcoin, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes
in 2009, Nakamoto designed a digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura
Bitcoin mining is a process of using computer hardware to calculate transaction confirmation and improve security. Bitcoin is a reward for miners to calculate and confirm
bitcoin also has a hype mode. Similar to bitcoin, there are also flow ores. Flow ores also have ways of trading and speculation, but the mining principle of flow ores is different from bitcoin. Flow ores mainly collect the idle bandwidth of miners and give them rewards
in fact, the blockchain technology adopted by bitcoin is more valuable than itself. This is a new way of information storage. The data is stored in all devices connected to the network. When new devices join, the information will be updated automatically, and all devices have the right to read the information
to understand the significance of bitcoin from the perspective of currency, we need to understand the currency itself first, and then compare it with the characteristics of bitcoin. After comparison, I think that bitcoin is a very high-quality currency, but some people don't think it is. They mainly question the formation mechanism of bitcoin and the lack of national credit as guarantee. They think its foundation is relatively weak
at present, there are quite a lot of arguments about bitcoin in academic circles. For example, if the total amount of bitcoin is certain, then whether it will cause deflation or inflation has different views. I think it's deflation, and the value of bitcoin will be higher and higher
at present, bitcoin still means a little bit of a safe haven currency. When the news of brexit came out, the transaction price of bitcoin rose by 20% - 30% to about 4500 yuan / piece
the biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
the concept of bitcoin was first proposed by Nakamoto in 2009. Bitcoin, also known as bitcoin, is an open source software designed and released according to the idea of Nakamoto Tsung, and a P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution. It uses distributed databases throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation
mining needs time, money or space, not just shouting
if not, it is not recommended to stay at home. It requires more energy. If you do, you may not get it. More likely than not
Mining sounds good. In fact, it's just the pain on the surface and behind. Who can say
don't look at making money, it's only a few people who make it, but more people make soy sauce
if you go out to find a job to do mining, don't think about it. It's not suitable.
the person has at least one home [2]
there is at least one object [4] in at least one of the person's homes [3]
according to the current standards, the object is classified as mineral [5]
if the above conditions are met at the same time [6], it can be said that there is a mine at home
considering the spatial symmetry of physical rules [7], there is no academic research showing that there is a clear causal relationship between the spatial metric tensor [8] and the urban hierarchy [9], so the above conclusion should be applied to the internal space of cities at all levels, including the first tier cities [10]

^ in biology, human usually refers to Homo sapiens (scientific name: Homo sapiens), and occasionally refers to prehistoric species of Homo genus, which is a part of primate and Hominidae. The members of Homo genus are generally evolved from APE / hominoid. The fossil Homo sapiens shows that modern humans evolved in the East African Rift Valley about 200000 years ago. Human beings have more developed brains than other animals, which can carry out complex calculations and abstract thinking. In addition, the upright human body allows the human forelimb to move freely, so the human use of tools is far more than any other species. Human beings also try to explain natural phenomena with philosophy, art, science, myth and religion. This strong curiosity led to the development of advanced tools and science and technology. Like other primates, humans are social. The social communication among human indivials creates a wide range of traditional customs, religious systems, values and laws, which together constitute the basis of human society. People are especially good at communicating, cooperating, expressing themselves, communicating, exchanging opinions and organizing things with spoken language, gesture, body language and written language. By 2012, the world's population had exceeded 7 billion, about 6% of all the people who had lived on the earth
^ refers to a living space as an indivial, a family or a member of a tribe, usually a house or other building, or a compound house, a camp, a boat house or a cave. It is a place where indivials or families can eat, sleep and store their property. It is also the center of people's emotion. According to Article 12 of the Universal Declaration of human rights, the residence of an indivial is not allowed to be infringed unreasonably
^ interior is a term in point set topology. The "interior" of subset S in topological space is defined as the union of all open subsets of S. Intuitively, it can be thought of as "not on the boundary of s". The interior point of S is called interior point of S. Another equivalent definition is that the interior of S is the complement of the closure of s complement. In many cases, the concept of interior is antithetical to the concept of closure. The exterior of a set is the interior of its complement, which is equivalent to the complement of its closure; It contains points that are neither in the set nor on the boundary. The interior, boundary and exterior of a subset together divide the whole space into three parts (or less, because they may be empty sets). The interior and exterior are always open, and the boundary is always closed. A set without an interior is called a boundary set
^ objects can be described by classical mechanics or quantum mechanics; We can also use scientific instruments to do objective experiments to prove the correctness of these theories. This includes the measurement of position, or orientation in space, and the change of these measurements e to the application of force
^ minerals are pure crystalline substances (simple substances or compounds) formed naturally under geological processes. Absolute purity does not exist, so the purity here refers to the relatively single chemical composition of substances. Minerals are the basis of rocks (such as quartz, feldspar and calcite are common rock forming minerals), but minerals are different from rocks. Minerals can be expressed by their chemical formula, while rocks are composed of many minerals and non minerals without a certain chemical formula. Minerals are mostly inorganic compounds proced by abiotic organisms, generally solid, with ordered atomic structure, but there are also liquid minerals, such as mercury (mercury). The precise definition of minerals is still controversial. The two controversial conditions are abiotic proction and ordered atomic structure. Like limonite, obsidian and other similar minerals, but no crystalline substance, will be called quasi mineral
^ conjoint proposition, also known as conjunctive proposition, is a proposition that reflects the simultaneous existence of several situations or properties of things. In terms of logical structure, the disjunctive proposition is formed by the logical conjunction "and" connecting the branch proposition. Its branch proposition is called syntagmatic branch, which is usually expressed by P and Q. The logical form of conjoint proposition can be written as P and Q, and the sign is p Λ Q ("P and Q"). Λ is called conjunction
^ symmetry is a core concept in modern physics. A system transforms from one state to another. If the two states are equivalent, then the system is symmetric to the transformation. If the system changes from one state to another equivalent state, it is said that the system is symmetric to this operation. It refers to the invariance of a theoretical Lagrangian quantity or equation of motion under the change of some variables. If these variables change with time and space, but Lagrangian quantities or equations of motion remain unchanged, then this property is called "local symmetry". On the contrary, if these variables do not change with time and space, then this property is called "global symmetry". The simplest examples of symmetry in physics are the Galilean transformation invariance of Newton's equation of motion and the Lorentz transformation invariance and phase invariance of Maxwell's equation< In Riemannian geometry, metric tensor is also called Riemannian metric, which is translated as metric tensor in physics. It refers to a second-order tensor used to measure distance, area and angle in metric space
