Original mining
mining is to confirm the transactions in the bitcoin system over a period of time and record the process of forming new blocks on the blockchain. The miners are called miners
Can mining make money? People around me who have been in contact with blockchain have asked me this question. The answer must be yes, otherwise mining will not be the foundation of blockchain development, and countless people will be miners How to dig? Xiao users said they were at a loss. You can use ha Yu miner to mine and experience mining resistance by yourself. You can download software and mine with one click, without any learning cost
first of all, mining is the main way to obtain bitcoin, but the current threshold of mining is relatively high. If you choose to mine by yourself, first you need to understand certain technology, then download the bitcoin client and mine by yourself according to the online bitcoin mining tutorial
however, in theory, bitcoin can still be mined with computers or graphics cards. However, e to the development of mining instry in recent years, the whole network computing power of bitcoin is extremely terrible (more than supercomputers), so if you want to mine with computers or graphics cards, you can't find bitcoin, If you want to dig bitcoin, you still need to buy mining machines. Now the better mainstream mining machines in the market have to be tens of thousands. Of course, there are cheap second-hand mining machines, but these second-hand mining machines are all obsolete ones, and the electricity cost of mining is relatively high
in addition to the second way of direct purchase, the digital currency exchange is a special place for bitcoin trading. If you want to own a bitcoin, you can buy it directly with money. However, it should be noted that there are many digital currency exchanges in the market at present. Many small exchanges are specialized in cutting users and eating customer losses for a living. Therefore, when choosing an exchange, it is better to focus on the head exchange. For example, Hufu, one of the head exchanges in China, I have been using it for nearly two years, and it is very stable and safe.
we can go to the mine for half an hour every day through shigongtou. Although it's only a short half hour, it's the fastest way for novice players to earn Yuanbao. Because the difficulty of each level is different, players of level 35 or so can go to the third floor of the mine, while those of level 35 or below can go to the second floor of the mine, As for the first floor, because the shipment is too rubbish, we do not go mining
after entering the mine, we will find a large number of zombies around us. The level of zombies on the third floor is level 40. As long as our combat power is not too low, we can easily solve them. After that, we need to find a safe place to speed up mining. Here, new players choose the corner, where we are not easy to be found by other players, It's only 2 zombies that can be refreshed at most once around, which is very easy for us to solve
as long as we persist in mining for half an hour every day, we can purify at least 20 pieces of 5-quality black iron ore at the end of the day. According to the price in the game, we can get 60 yuan. For today's 50 equipment weaving, we only need to mine for two to three days to replace a set of 50 level equipment, As for weapons, we still have to work hard for a week to buy a powerful weapon.
bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (a blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, including all transactions in the bitcoin network)
mining is a process of increasing bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times. Miners offer algorithms for bitcoin networks in exchange for the opportunity to get bitcoin rewards. The miners verify each new transaction and record it in the general ledger. Every 10 minutes, a new block will be "mined", and each block contains all the transactions from the generation of the previous block to the present, which are added to the blockchain in turn. We call the transactions included in the block and added to the blockchain "confirmed" transactions. After the transaction is "confirmed", the new owner can spend the bitcoin he gets in the transaction
there are two types of rewards for miners in the process of Mining: the new currency reward for creating a new block, and the transaction fee for the transaction contained in the block. In order to get these rewards, miners compete to complete a mathematical problem based on encrypted hash algorithm, that is, to use bitcoin mining machine to calculate the hash algorithm. This requires strong computing power, how much the calculation process is, and whether the calculation results are good or bad. As the proof of miners' calculation workload, it is called "workload proof". The competition mechanism of the algorithm and the mechanism that the winner has the right to record transactions on the blockchain ensure the security of bitcoin
miners also get transaction fees. Each transaction may contain a transaction fee, which is the difference between the input and output of each transaction. A miner who successfully "digs" a new block in the process of mining can get all the transaction "tips" contained in the block. With the decrease of mining reward and the increase of the number of transactions in each block, the proportion of transaction fee in miners' income will graally increase. After 2140, all miners' earnings will be made up of transaction fees
mining is a process of decentralizing settlement, in which each settlement verifies and settles the processed transaction. Mining protects the security of bitcoin system, and achieves the consensus of the whole bitcoin network without a central organization. The invention of mining makes bitcoin very special. This decentralized security mechanism is the basis of point-to-point e-money. The reward and transaction fee for casting new coins are a kind of incentive mechanism, which can regulate miners' behavior and network security, and at the same time complete the currency issuance of bitcoin.
Primitive human beings have been able to collect stones, grind them into proction tools, and collect clay for pottery making, which is the earliest germination of mining. Mining in ancient China has a long history. Unearthed from the ancient copper mine site in Tonglushan, Daye, Hubei Province, are various proction tools made of copper, iron, wood, bamboo, stone, pottery, copper ingot, copper weapons, etc., which are used for mining, loading, lifting, drainage, lighting, etc., and prove that the combined development of shaft, inclined shaft and drift has been used in the spring and Autumn period, and the underground mining system has initially formed. By the Western Han Dynasty, the mining system had been quite perfect. At this time in Hebei, Shandong, Hubei and other places of iron, copper, coal, placer gold and other mines have begun mining. At the end of the Warring States period, Li Bing, the governor of the state of Qin and Shu, g salt wells in Shuangliu County, Sichuan Province. Before Ming Dynasty, iron, copper, tin, lead, silver, gold, mercury and zinc were mainly proced. At the beginning of the 17th century, Europeans used the black powder imported from China for mining, and replaced manual mining with rock drilling and blasting, which was a milestone in the development of mining technology. At the end of the 19th century and the beginning of the 20th century, mining explosives, detonators, detonating cords and rock drilling equipment were successively invented, forming modern blasting technology; The use of electric mechanical shovel, electric locomotive and electric lifting, communication, drainage and other equipment has formed modern shipping technology. Since the first half of the 20th century, mining technology has developed rapidly, with the emergence of ammonium nitrate explosive, the use of underground deep hole blasting technology, the continuous improvement and large-scale of various mining equipment, and graally formed mechanized mining technology suitable for different deposit conditions. The scientific methods of mine design, deposit evaluation and mine plan management are put forward to make mining develop from technology to engineering science. After the 1950s, e to the use of down the hole drill, cone drill, self drilling jumbo and other new equipment, mining equipment to achieve large-scale, transportation and lifting equipment automation, the emergence of unmanned locomotives. Computer technology is used in mine proction management, planning and design and scientific calculation. System science is used to study mining problems, and system mining engineering is born. Mine proction began to establish automatic control system, using modern test equipment, testing technology and electronic computers to predict and solve some practical problems. Therefore, the subject of mining engineering has been formally proposed and recognized
