Exponential weighted hash rate of ore pool

1. mining pools are arranged according to computing power. For example, the computing power of digyi mining bitcoin mining pool accounts for about 4% of the total network computing power, ranking among the top ten mining pools in the world. The four technology blockchains are relatively good.

2. Mining is actually competing for the right to pack in the block
as tens of thousands of miners compete for the right to pack, the probability of a single miner seizing the right to pack is very small, and the output is very unstable. It is possible to grab the right once an hour or not once a year
in order to stabilize the mining output, miners often choose to join the mining pool. The mining pool integrates the computing power of a large number of miners and occupies a certain share in the total computing power of the whole network, so as to obtain a more stable mining output. After charging 2% ~ 4% of the pool handling charge, the output is distributed to the miners according to the miners' computing power
it's just like that it's hard for one person to win the lottery, so the mine pool organizes many people to buy the lottery together, and after winning the lottery, they are distributed to everyone according to the amount of contribution.

3. The mining machine of bitfish mine is a cluster mining machine with high computing power. The era of CPU mining has long passed, and GPU mining is not the mainstream. Now bitfish mine is an era of ASIC mining and large-scale cluster mining. Looking back on the mining history, bit mining has gone through the following five times: CPU mining, GPU mining, FPGA mining, ASIC mining, large-scale cluster mining, while the mining chips are updated, the mining speed changes are: CPU (20mbash / s), GPU (400mbash / s), FPGA (25ghash / s), ASIC (3.5tash / s), large-scale cluster mining (3.5tash / s * x), At present, bitfish is simulating quantum computing, but it is still a high computing power cluster miner.

Since July 1947, the war of liberation has turned into a stage of strategic attack, and the trade and material exchanges between the liberated areas have become increasingly frequent. Because the currencies issued by the banks in the liberated areas are not unified, resulting in the situation of mixed circulation of various currencies, the transaction should be converted according to the price ratio, which affects the smooth progress of proction circulation and economic exchanges. It is imperative to unify the currencies in the liberated areas

On October 8, 1947, the central government made a clear instruction on this proposal: "it is too early to establish a unified bank at present, and it is necessary to make preparations. As for the name of the bank, it can be used & # 39; The people's Bank of China. "

In this way, the name of "people's Bank of China" was defined by the central government. On December 1, 1948, the people's Bank of China was formally established and issued the new China's unified currency in Shijiazhuang, where the head office of the people's Bank of China is located. Because the currency is issued by the people's Bank of China and is the currency of the people's Republic of China, it is named "RMB". At present, the currency unit in use in China is Renminbi yuan, or RMB yuan

extended information:

the first set of RMB was issued under the special background of wartime. There were a total of 12 denominations and 62 editions, which were quite different from each other. The number of issuance and circulation of some editions was very small. In addition, the raw materials for coining came from local sources, resulting in the uneven quality of banknotes. With the issuance and circulation of the second set of RMB, on May 10, 1955, the first set of RMB in China had been in circulation for nearly eight years and then stopped using in the whole country. It has been 50 years since then

after years of changes, the first set of RMB is very rare in the world, and its value of appreciation, commemoration, collection and investment is increasing day by day, which is particularly favored by well-known auction houses and cultural relics collectors. According to the data of the 2005 "red sun Spring Festival auction - special spot of postal currency card", two consecutive 5000 yuan "shepherd's pictures" started at 5000 yuan. After several times of bidding, they finally won at 120000 yuan

five thousand yuan "Weihe bridge", also from 10000 yuan to 85000 yuan; The final transaction price of Wu Wanyuan's "new Huamen" was 260000 yuan. According to this ratio, if the "top four treasures" can show up at the auction, it will be a sky high price of more than one million

5. Bitcoin is the ancestor of all virtual currencies, and its price and value have been obvious to all for eight years. However, for the newcomers who lack experience and technology, it is very risky to simply speculate in bitcoin. Another operation method and profit model (I personally test, extremely low risk, stable income, practical) may allow you to better control the wealth of bitcoin—— Seagull teacher, eight years of Internet Finance veteran.

6. 1. Lightning network

lightning network is a kind of chain breaking technology, which uses layer 2 to eliminate the transaction processing capacity of bitcoin

examples of terminology usage

bitfinex plans to implement tether based lightning network (usdt)

detailed description

if lightning network is introced, it is possible to trade outside the crowded blockchain, so as to speed up the transaction speed and rece the cost. If you can speed up transactions and rece costs, you can make small payments, which is expected to create new procts and services

6. Mining pool

Mining pool is an organized server, which is created to collect the hash value of each miner and cooperate in mining

examples of terminology usage

the rewards earned by the virtual currency exchange binance in the mining pool can be directly traded by binance

detailed description

in the mining business of vital scale, a mechanism for multiple miners to cooperate in mining. The reward is paid according to the contribution of the mining

7. Half life

half life refers to the time when the mining reward (= new circulation) of bitcoin and other virtual currencies is reced by half

examples of terminology usage

cryptocurrency bitcoin (BTC) will reach its third half-life on May 12, 2020, and the mining reward will be reced from 12.5 BTC to 6.25 BTC

detailed description

many virtual currencies have "issuance limits" to prevent inflation, and the new issuance will be reced by half every certain interval of half-life. This is also a noteworthy event unique to virtual money, because with the decrease of supply and the rising of price, the scarcity value increases significantly
