1. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. 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

2. You'd better describe your miner's hardware configuration, system architecture, operating system and other information, and find a suitable solution for you according to the relevant information.
3. Bitcoin can be understood as a stock, and mining machinery is the employee of the stock. Working for the stock, the stock can be bought and sold as well as transferred as money. When transferring money, users need to pay a service charge, just like bank transfer. The service charge is to pay the wages of the mining machine, so the mining machine has income. After receiving the service charge (BTC), the holder of the mining machine can take it to the exchange to sell it, which is equivalent to making money. Because of the evolution of the market over the years (omitting 10000 words here), now the income is very stable and high, so more and more people are engaged in mining. You can check more on the Internet and search today's miners. There are many articles suitable for Xiao to read.
4.
Bitcoin's overall market is not optimistic, continuing the stagnant or even backward market in 2014. The price of bitcoin once fell below the 1000 yuan mark and soared to 3000 yuan when hot money entered. The stock market fell sharply some time ago. It is possible that the price of bitcoin once exceeded the 2000 yuan mark e to the transfer of some stock market funds to the currency market. At present, the price of bitcoin hovers around 1500 yuan, Here is the K-line chart of bitcoin price since 2015:
5. The learning ledger can track all the learned knowledge and skills stored in the ecation blockchain. Each ecation blockchain represents the formal or informal learning effect achieved by learners within an hour, and each ecation blockchain can be presented to other learners. Learners can get ecation blockchain from both formal ecational institutions and workplaces
what attracts more attention is that the proponents of the concepts of "learning ledger" and "ecation blockchain" claim that they can track and record the real-time income of learners, so as to analyze and determine which knowledge, skills, courses or majors can bring more rewards to learners, so as to provide advice and guidance for later learners; Learners themselves can also use the "learning account book" to seek sponsors who are willing to invest in their learning. The principle behind this is that the "learning account book" can track and record the rewards that learners get through each ecation blockchain, so the sponsors can ask for a certain proportion of the learners' income as their return on investment, The protocol between learners and investors is managed by smart contract. Like bitcoin's technology foundation, "learning ledger" is also built on blockchain technology, which means that every ecation blockchain acquired by learners will become an eternal record of knowledge and skills that are constantly increasing and will not be deleted on the "learning ledger"< br /> MOOCS and open ecation resource movement, which are born out of technological innovation, have and will continue to reconstruct the essence, connotation and boundary of ecation in the era of sharing economy, reshape the mission, function and organization mode of ecational institutions in the digital era, and promote the reform of teaching philosophy, content and mode in the teaching environment of technology empowerment. The development and application of blockchain technology has created a new technical basis and practice mode for the reform of ecation and teaching.

6. Calculation method
1. Calculate I = Dmax / Dmax by the ratio of the maximum particle size of the material before crushing and the maximum particle size of the proct after crushing, where Dmax is the maximum particle size of the material before crushing; dmax― http://www.ysxuankuang.com/cpzx.html - the maximum particle size of the material after crushing
2. The ratio of the effective width of the feeding port and the width of the discharging port of the crusher
I = 0.85b/b
where
b --- the width of the feeding port of the crusher; B --- Crusher & lt; Width of discharge port
0.85 -
ensure the effective width of the crusher gripping the material. The maximum width of discharge port is selected for coarse crusher; Take the minimum width of discharge port for middle crusher
3. Calculate with average particle size
I = DCP / DCP
where
DCP - average diameter of material before crushing; DCP - average diameter of crushed material. The crushing ratio obtained by this method can truly reflect the crushing degree of sand and stone equipment.

7. The length of tension adjusting spring of Nanchang mining machine hook C 1000 jaw crusher is 20
8. It can be divided into six categories according to the crushing mode and the structural characteristics of machinery (action principle)< (1) jaw crusher (tiger mouth). The crushing action is that the movable jaw plate periodically presses the fixed jaw plate to crush the ore block sandwiched in it< (2) cone crusher. The ore block is between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block< (3) roller crusher. In the gap between two opposite rotating round rollers, the ore block is mainly crushed continuously, but it also has the function of grinding and stripping, and the toothed roller surface also has the function of splitting< (4) impact crusher. The ore block is broken by the impact of fast rotating moving parts. Belong to this category can be divided into: hammer crusher; Cage crusher; Impact crusher< (5) grinding machine. The ore is crushed by the impact and grinding of grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder
(6) other types of crushing mills

9. Crusher can be divided into coarse crushing, medium crushing and fine crushing according to the size of feeding and discharging
the current general classification principle of crushing equipment is based on crushing method, mechanical and structural characteristics (action principle). According to this classification, it can be roughly divided into:
1)
jaw crusher, which presses the movable jaw plate to the fixed jaw plate periodically to crush the materials in it. Both jaws are rectangular. According to the swing form of jaw plate, the jaw crusher can be divided into simple swing and complex swing
2)
cone crusher, the material is between the inner and outer cones. The outer cone is fixed, and the inner cone swings eccentrically, so as to crush or break the material sandwiched in it. The present crushers belonging to this category can also be divided into round crushers with sharp and steep cones for coarse crushing, and cone crushers with gentle cone inclination for medium crushing and fine crushing
3)
roller crusher. In the gap between two opposite rotating rollers, the material is mainly crushed continuously, but also ground. The surface of toothed roller has the function of splitting. Belonging to this category can be further divided into smooth roll surface (often known as roller machine) and toothed roll surface
4) impact crusher. The material is broken by the impact of fast rotating moving parts. This category can also be divided into: (1) fast rotating parts mainly hammer, known as hammer crusher; ② The material is broken by a rotating rigid rod rigidly connected to a rotating disc, which is called cage crusher, as well as the past pounder and the recent impact crusher
5)
grinding machine. The material is broken by the impact and grinding action of grinding medium (ball, bar, gravel or ore block, etc.) in the rotating cylinder.
