Production process of BTC coin hot Wallet

1.

It can't turn. These are proxy websites, where can I convert currency

according to the 2017 Credit Suisse report, the number of millionaires in the world is about 36 million. Therefore, if a "bitcoin club" composed of users with more than one bitcoin is established, the number of members of the club will not exceed 21 million, less than the number of global millionaires

bitcoin is graally released through the so-called "mining", and today it has issued more than 85% of the total. It's going to get slower and slower, and it's going to stop completely by about 2140. At present, bitcoin's annualized inflation rate (3.7%) is far lower than that of the US dollar since 2008 (36%), and it will further drop to 1.7% after half a day's rection next year

theoretically, one bitcoin can be infinitely subdivided by expanding the precision of digital storage or by upper layer expansion (such as lightning network technology). However, the transfer fee actually limits the value of bitcoin, which is too small. Therefore, the current code only supports subdivision to one in 100 million. The unit calls it "cong", which is named by netizens in memory of the inventor of bitcoin, Nakamoto. Don't say that one bitcoin is too expensive, because you can buy 0.1 or 0.01

bitcoin is in the address. Address is a number, but for the convenience of writing and using, it is encoded into a string form. The bitcoin address is generated by the private key of bitcoin through cryptographic calculation. This generation process does not need Networking (because mathematical calculation does not need Networking), and can be generated offline on your own computer

2. 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
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start
after completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to post the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost.

Every other time, the bitcoin system will generate a random code on the system node. All computers in the Internet can search for this code. Whoever finds this code will generate a block and get a bitcoin. This process is often called mining

at present, one bitcoin is divided into eight decimal places based on the current data structure, that is, 0.00000001btc. The smallest unit of bitcoin g by miners is 0.00000001btc

generally speaking, bitcoin is like a gold mountain with a total amount of 21 million gold coins. To get it, players need to use the computing power of the computer to calculate a group of numbers according to the existing algorithms

extended data:

unlike all currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, And the use of cryptography design to ensure the security of all aspects of money circulation

the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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

4. 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

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system.

7. There is no such word, only zebra, which means zebra
zebra is the general name of zebra subgenus (scientific name: hippotigris) and zebra subgenus (scientific name: dolichohippus), which is a common equine animal in Africa. Zebras are named for their protective stripes, which are different from each other
this species is named zebra by famous travelers and naturalists. The earliest specimen sent to the British Museum is from South Africa. Zebra stands about 135 cm, 54 inches across the shoulder, weighs about 700 pounds, has a horse like appearance, no droop, and is typically characterized by its black nose and straight mane on its neck. The male is slightly larger than the female. There is a narrow dark stripe on the back, extending from the top of the back to the tail of the mane. The texture of the female is wider
zebra is an African specialty. The mountain zebra of South Africa is densely covered with wide black stripes except the abdomen, and the male has drooping flesh in the throat. Common zebra of Eastern, central and southern Africa with or without stripes from legs to hooves. The alt zebra is about 2.7 meters long. Its song sounds like a wild goose. Only its head, shoulder and nape are striped. Its legs and tail are white. It has a dark dorsal line. East Africa also proces a type of zebra, the largest, ears long (about 20 cm) and wide, narrow and dense stripes, so it is also known as the zebra with fine stripes
zebra distributed in Botswana, Democratic Republic of Congo, Ethiopia, Kenya, Malawi, Mozambique, Namibia, Rwanda, Somalia, South Africa, Sultan, Swaziland, United Republic of Tanzania, Uganda, Uganda, Uganda. It is rarely distributed, mostly in Africa
body length 200-240 cm, shoulder height 120-140 cm, tail length 47-57 cm, weight 350 kg. In addition to the abdomen, the whole body is covered with wide black stripes, which has a protective effect. It is widely distributed in eastern, central and southern Africa and inhabits in the tropical grassland with abundant water and grass. Generally, they live in a small group of 10-12 headed by an alt male, sometimes mixed with other animals such as antelope, takin, impala and ostrich. When there is a shortage of food, large groups of people can migrate. There are several subspecies, such as the zebra
the vowel e pronounces the long vowel / I / in the stressed open syllable. When pronouncing, the tip of the tongue is close to the lower teeth, the front of the tongue is raised very high, but does not touch the upper jaw, there is no friction, the gums are close to each other, and the lip shape is flat. This sound appears at the beginning, middle and end of the word, For example:

hope I can help you solve your doubts.

8. Yesterday, which big official has already said that it will not recognize the legitimacy of bitcoin

9. According to the previous news, the height of Ethereum block is now adjusted to 4730660! Ethereum is a new and open blockchain platform, which allows anyone to build and use decentralized applications running through blockchain technology in the platform
just like bitcoin, Ethereum is neither controlled nor owned by anyone - it is an open source project created by many people around the world. Different from bitcoin protocol, Ethereum's design is very flexible and adaptable. It is very easy to create new applications on the Ethereum platform. With the release of homestead, anyone can use the applications on this platform safely
Ethereum is a programmable blockchain. It does not give users a series of preset operations, but allows users to create complex operations according to their own wishes. In this way, it can be used as a platform for many types of decentralized blockchain applications
in a narrow sense, Ethereum refers to a series of protocols that define a decentralized application platform. The core of Ethereum is Ethereum virtual machine (EVM), which can encode any complex algorithm. In computer science terminology, Ethereum is "Turing complete.". Developers can use the existing JavaScript and python as the model of other friendly programming languages to create applications running on the Ethereum simulator.

10. I only know about silver coins, but it should be similar to other coin making methods
the steps of making silver coin are as follows:
1. Ingredients: the raw materials of silver coin proction are precious metal silver and ordinary metal copper, the weighing accuracy is relatively high, and the batch weighing of raw materials, semi-finished procts and finished procts is completed by the balance. See the diagram of the special balance used in Shanghai Museum (300kg each time, accuracy of 0.01oz). In the early days, coal and coke were the main fuels for furnaces, and then diesel and gas were used. The maximum amount of silver melting in each furnace is 150 kg. The manufacturer melts all kinds of raw materials in large crucible according to the specified proportion, and fully prepares the casting embryo
2. Mold making: the engraving machine is the main equipment for mold making in the mint. Based on the principle of similarity in geometry, the relief works designed and made by craft artists are reced into molds, which are called original molds or direct molds. The original engraving machine was operated manually. The figure below shows the 1936 French TVR automatic engraving machine. The coinage was made of molds, including design drawings, oil and clay relief, plaster and copper molds, and then the original molds were made by engraving machines. When working, copper mold is placed on the right side of the engraving machine, and mold blank to be processed is placed on the left side. The scale of engraving can be adjusted according to the needs. Now the Yangwen mould, which is called mould, can be seen sporadically in the collection market, is actually copper mould embryo
3. Working die for making silver coin mold: the original die is usually engraved with positive characters, which can not be directly used for proction, but needs to be turned into working die. There is a large demand for the working die for the proction of currency. In the actual process, the original die of Yin Wen is made from the original die of direct carving, and then the original die of Yin Wen is made into binary die and working die in turn, and then proced by the embossing machine on the working die. The manual screw press on the exhibition stand is an early turning die equipment of the mint. It uses four workers as the power to turn the die for the mint
4. Casting is to melt the finished metal and inject it into the casting mold to form strips. After casting, the strips are rolled by a tablet mill to form the standard thickness required for coinage. Rolling machine, also known as rolling machine or rolling mill, is divided into rough rolling and finish rolling. After eight rolling processes, the silver bar was rolled from 560mm to 250mm. Because the rolled silver sheet is too long to be reprocessed, it needs to be segmented by scissors machine and then rolled to the standard thickness required by the coin through the finishing process
5. Making embryo cake: the blank cake for printing silver coins is finished by punch (see the figure below). The strips of standard thickness enter the die through the automatic feeding roller on the special punch, and the blank cake is punched. The punch on display punches 180 pieces per minute. The edge chips are automatically cut into short films and returned to the melting place after weighing
6. Heat treatment of cake embryo: after cold rolling, the silver material becomes brittle and hard, which is not concive to pressing patterns. It needs to be annealed in baking furnace to restore the original softness, and the baking temperature reaches 700 ℃. After baking, the surface of the cake is oxidized, and the cake needs to be washed with acid solution to remove the oxide layer
7. Edge rolling: the last process before printing is edge rolling. Smooth edge machine, also known as edge rolling machine. The blank cake passes through the groove between the turntable of the trimming machine and the crescent shaped edge plate to make the edge convex, which is convenient for the pattern forming ring the embossing and can rece the wear of the pattern ring the circulation. The schematic diagram is shown below
8. Straight tooth silver coin stamping: the embossing machine is a special equipment for coin forming, which prints the pattern on the die on the blank cake and the wire teeth on the die ring on the edge of the coin. The Silver Circle press in the figure below was manufactured by Waterbury Farrell foundry and machine manufacturing company in 1921. The working pressure is 160 tons, and each machine can proce 105 pieces per minute. Each machine is operated by two employees, one is responsible for adding green cakes, and the other is responsible for stacking the green cakes. The inner ring gear in the middle of the figure below completes the silver round tooth edge. The first mock exam is made of steel and die, which is used to ensure the uniform diameter of silver dollar when printing. The edge teeth pattern (the same side of the coin) is also completed at the same time. The machine pressure is between 30-200 tons. Take us dollar as an example: one cent (3.11g) and one jiao (2.5G) 40 tons, five Fen (5g) 60 tons, twenty five cents (6.25g) 110 tons, five jiao (12.5g) 110 tons, one yuan alloy new coin (8.1G) 80 tons, early one yuan silver coin (26.73g) 140-160 tons. At that time, the Shanghai Central Mint proced 26.7g ships with a pressure of 160 tons and a speed of 100 coins per minute. Please note that the steel mold moves up and down at the same time, and only the upper mold moves down when punching the coin cake. Explain that the inner gear ring is processed by gear shaper cutter, so we can see that there are two thin clamping lines in the bottom groove of most real silver round edge teeth, which is the trace left by gear shaper cutter on the mold reflected on the silver round teeth. The internal gear ring can only be processed by gear shaper, and the cutting tool is processed from the top of the tooth, that is, straight lines, one by one to the root of the tooth. Then the inner ring gear should be tempered to form a hard tooth surface, so that the inner ring gear becomes a tool. It turns out that the mark of the first knife on the top of the inner tooth of the shaper knife becomes sharp, so it will leave two thin lines on the groove at the bottom of the silver coin. Please observe carefully. This is an important point in distinguishing between genuine and fake silver coins
9. The manufacture of the tooth edge of the early lace silver coin: the stamping of the lace silver coin was completed in two steps, and the inner gear ring of the upper step was smooth, which was only responsible for the positioning of the cake embryo and the size of the limit value, not for the printing pattern. Then roll the lace
10. Finished proct inspection: the stamped coins must be inspected to eliminate the waste procts, and the silver coins need to be weighed, inspected and inspected. The use of wooden cake detector is a machine for manual inspection of coin surface quality. Two people operate the machine, and the coin turns over automatically. Each Inspector checks one side. The silver coin automatic calibration machine is used. Each machine has 10 automatic balance, which is used to remove unqualified procts. Its inspection accuracy is 78 mg, and 150 silver coins are inspected every minute.
