What are the mining rules of symbiotic coin H2 >
30% of the total amount of symbiotic coins issued will be obtained through mining, with a total of 8.4 billion symbiotic coins. Mining can be divided into two stages:
the first stage is the preheating period, ring which 10 million symbiotic coins will be generated through mining every day, lasting for 50 days. All the participants (miners) who use the mining procere and meet certain conditions will share the symbiotic coin proced every day
the second stage is the formal period, ring which the remaining 7.9 billion symbiotic coins will be graally released in the form of mining within 10 years. Every year, the number of symbiotic coins obtained by mining will be reced by 40%
compared with the previous year
< H2 > minerblock development backgroundnow there are more and more digital cryptocurrencies. Although there have been several mining disasters before, it still can't stop people from mining. Especially in foreign countries, in order to mine, it is very necessary, even the browser is used. Pirate Bay, a well-known BT website in the world, contains special code and will steal users' computer resources to help them mine. Coincidentally, similar things happen to other websites and extensions. Now there are experts writing extensions, so that when you surf the Internet, you won't be stolen by these websites to become a part of zombie mining. As we all know, once you start mining, there will be a lot of resources in the information system, and this extension of minerblock can help you prevent some websites from mining with browsers

[prehistoric times: 1623-1895]
1623: w. schickard, a German scientist, built the first mechanical computer in human history, which can perform six digit addition, subtraction, multiplication and division< In 1642, French scientist B. Pascal invented the famous Pascal mechanical computer and established the concept of computing machine for the first time
1674: Leibniz improved Pascal's computer to be a machine capable of continuous operation, and put forward the concept of "binary" number It is said that this concept originated from the Chinese eight trigrams Bouchon invented the idea of "perforated tape."
1805: French mechanic J. jacquard completed the design and manufacture of "automatic jacquard knitting machine" according to buccio's idea of "perforated paper tape". In the early years of the development of electronic computer, we can find the figure of automatic jacquard in many famous computers
1822: British scientist C Babbage) built the first difference machine, which can handle three different 5-digit numbers with an accuracy of 6 decimal places< In 1834, Babbage proposed the concept of analytical machine, which is divided into three parts: stack, arithmetic unit and controller. His assistant is Ada, the only daughter of Byron, a famous British poet; ADA Augusta compiled the first computer programs for the analyzer in human history
ADA and Babbage have made immortal contributions to the development of computer. Their foresight of computer is at least more than a century ahead. It is their hard work that laid a solid foundation for the emergence of computer< In 1847, British mathematician g. Boole published his book mathematical analysis of logic
1852: ADA and Chen 8226; ADA Augusta died at the age of 36
in 1854, Boolean published "the study of the law of thinking -- the mathematical theoretical basis of logic and probability", and synthesized his other article "the mathematical analysis of logic", thus creating a new discipline Boolean algebra, which provides an important mathematical method and theoretical basis for the switch circuit design of digital computers
1868: Christopher, American journalist; C. Sholes invented the QWERTY keyboard that is still in use today
1871: Babbage (C Babbage died. The analytical machine he and ADA envisioned failed to come out in the end, but they left a valuable legacy for later generations, that is, the indomitable spirit in the face of difficulties, as well as dozens of design schemes and proceres< In 1873, F. Baldwin, an American, made the first hand-held computer by using the gear with variable number of teeth invented in the past< In 1886, American Dorr E. felt (1862-1930) made the first calculator operated by buttons
1890: in the 12th census of the United States, the tabulator invented by statistician Dr. h. Hollerith was used to complete the first large-scale data processing in human history. After that, Hollerith founded his own tabulator company according to his own invention, and eventually evolved into IBM company
1891: Lilan & Chen 8226; Stanford and his wife are near Palo; The 8000 acre Stanford University in Palo Alto foreshadowed the birth of Silicon Valley
in 1893, Steiger, a German, developed a kind of computer called "tycoon", which was improved on the basis of hand-held computer, and occupied the market at that time by relying on good computing speed and reliability. Until 1914, before the outbreak of the first World War, this kind of "tycoon" computer had been selling well
1895: young British engineer, J Fleming invented the first electron through the "Edison effect"
[electron tube era: 1911-1946]
1911: on June 15, Wall Street financial investor C. flent invested in Hollerith's tabulator company and established a new CTR company, but the company did not set foot in any electronic field at the beginning, Instead, they make things like shredders or potato peelers
1912: the young American inventor de & Chen 8226; Forrest (L De forest first discovered the amplification effect of electron tube in Palo Alto Town, which laid the foundation for the electronic instry. Today, Palo Alto town has become the center of Silicon Valley
1913: Professor Wan, MIT, USA; V. Bush led the creation of the analog computer "differential analyzer.". The machine is driven by a series of motors, and the rotation angle of the gear is used to simulate the calculation results
1924: the father of Silicon Valley, Mr. Terman, was a professor at Stanford University, which played a decisive role in the establishment of HP and Stanford Instrial Park.
in February, the tabulator company founded by Hollerith underwent several evolutions, and finally changed its name to IBM, which we see today< In 1935, IBM made the IBM 601 punch card computer, which can calculate multiplication in one second
in 1936, Alan Turing published his paper on computable numbers and their applications in decision problems, which first expounded the principles of modern computers and theoretically proved the possibility of the existence of modern general-purpose computers. Turing decomposed the work done by human beings in calculation into simple actions, which is similar to human computation. Machines need: (1) memory, It is used to store the calculation results 2) A language for operations and numbers 3) Scanning 4) Calculation intention, that is, what to do next in the calculation process 5) Perform the next calculation. In one step, the calculation can be divided into: (1) changing the number symbol 2) Scanning area changes, such as carry to left and add to right 3) Change the calculation intention, etc. The whole calculation process uses binary system, which is later known as "Turing machine"
German engineer K. Zuse, who is more than 20 years old, has developed a mechanical programmable computer Z1 in binary form. Its theoretical basis is derived from Boolean algebra
in November 1937, G. Stibitz, a researcher of at & T Bell laboratory, made the electromagnetic digital computer "model-K"
1938: Claude & Chen 8226; Elwood & Chen 8226; Claude Elwood Shannon published his famous paper "symbolic analysis of relay and switch circuit". It is the first time to use Boolean algebra to analyze switch circuit. It is proved that logic operation of Boolean algebra can be realized by relay circuit. At the same time, the design method of electronic circuit to realize addition, subtraction, multiplication and division is given clearly. This paper is the beginning of switch circuit theory
1939: New Year's day, bill, a graate student of Stanford University, USA; B. Hewlet and David H; Packard formally signed the partnership agreement and founded Hewlett Packard (HP), which is commonly known as HP in China
in September, Bell Labs developed the M-1 computer
in October, John Vincent atanasof (1903-1995) made the first prototype of the world-famous ABC computer, and put forward three principles of the computer: (1) to realize digital operation on the basis of binary logic, so as to ensure accuracy 2) Electronic technology is used to realize control, logic operation and arithmetic operation to ensure calculation speed 3) The structure of separating the function of calculation from that of updating and storing binary numbers is adopted. This is the famous three principles of computer< In September 1940, Bell Labs demonstrated the M-1 at Dartmouth University. They connected the M-1 computer installed in the campus with a telegraph line, printed out a mathematical problem on the spot and transmitted it to New York. The successful performance of M-1 computer at Dartmouth University realized the dream of long-distance control of computer for the first time< Weiner, the father of cybernetics, put forward five principles of computer: (1) it is not analog, but digital 2) It is composed of electronic components, and mechanical components are minimized 3) Use binary system instead of decimal system 4) Internal storage calculation sheet 5) Store data in a computer< In 1941, chuze completed the development of Z3 computer, which is the first programmable electronic computer. It can handle 7-digit exponent and 14 digit decimal. A lot of vacuum tubes are used. It can do three to four addition operations per second, and one multiplication takes three to five seconds< In 1942, John v. Atanasoff, who was then a professor of mathematical physics at Iowa State University, and Clifford berry, a graate student, assembled the famous ABC (Atanasoff berry computer) computer, which used more than 300 electron tubes. This is also the first computer with the rudiment of modern computer in the world. However, e to the official participation of the U.S. government in the Second World War, the computer did not really put into operation
in 1943, Bell laboratory put U-type relay into computer equipment and made m-2 computer, which was one of the earliest programming computers. In the following two years, Bell Labs successively developed M-3 and M-4 computers, but they are similar to m-2 computers, only the memory capacity is larger
in October, the computer nicknamed "giant" used to decipher the German code was successfully manufactured in brechley manor, England. Since then, several computers have been manufactured, making great contributions to the victory of the Second World War
August 7, 1944, funded by IBM, American Howard; The mark 1 computer developed by H. Aiken is officially running at Harvard University. It is equipped with 150000 components and 800 kilometers of wires, and can perform more than 200 operations per minute. Grace, a female mathematician; Huo Bo (G The computer can be used to solve differential equations. The advent of mark-1 computer not only realizes Babbage's long cherished wish, but also represents the highest level of mechanical computer and electric computer since the advent of Pascal computer
on February 14, 1946, Professor J. mauchiy and J. Eckert of Moore College of University of Pennsylvania jointly developed ENIAC (Electronic Numerical Integrator and computer): computer. The computer is installed with 17468 electron tubes, 7200 diodes, 70000 resistors, 10000 capacitors and 6000 relays. There are as many as 500000 welding points in the circuit. The machine is installed in a row of 2.75-meter-high metal cabinets, covering an area of about 170 square meters, with a total weight of 30 tons. Its operation speed reaches 5000 additions per second, Two 10 digit multiplication can be done in 3 / 1000 seconds< On December 23, 1947, William B. Shockley, John Bardeen and Walter H. brattain of Bell Labs created the first semiconctor amplifier in the world
