570 graphics card mining
"Graphics card mining" is actually to use the graphics card to dig bitcoin, so that the graphics card can work with high load, and the eliminated ones will become mine cards. Generally, the core PC board on the back of mine cards is seriously discolored< br />
2. Seven rainbow colorful1060 belongs to the game graphics card, which is the mainstream level and can be competent for all kinds of large-scale games.
you need to buy multiple PCI e motherboards, one motherboard needs 6 cards, the power supply needs to be rated above 1000W, the CPU has enough al cores, the memory is 4G, and the graphics card needs gtx1060 or AMD rx470 / 570 or above a card
just download the mining software to start
however, if you calculate the cost, one card needs 3000, six cards need 18000 or more, at least 500 power supplies, CPU 300, memory 300, motherboard and PCI extension cable need about 800, and one monitor. In this way, a simple mining machine will cost more than 20000, and the average power consumption of a graphics card is 200W (n card level, a card 250W). Six of them are 1200W. The whole machine has this power. One hour is 1.2 kwh, and one day is full load. The electricity charge of 16x1.2x0.6 + 8x1.2x0.3 = at least 17.85. Although using a card is more efficient, it costs more electricity
a miner can earn 100-200 yuan a day. How long will it take to recover the cost? Can the value of money still be at this level at that time?
Yes , on August 21, Beijing time, recently, TSMC officially announced that the 7Nm chips, which were put into large-scale proction in 2018, have now proced more than 1 billion 7Nm chips. At the same time, more than 100 procts began to use the 7Nm chips proced by TSMC
it is understood that TSMC's first 7Nm chip started large-scale proction in April 2018. Meanwhile, the billionth 7Nm chip was proced in July this year. In these 27 months, TSMC has to proce more than 37 million 7Nm chips every month
according to the data, the first batch of TSMC 7Nm procts include bitmainland's miner chips, Xilinx's FPGA chips, apple A12, Huawei's Kirin 980, etc

Introction to Taiwan integrated circuit manufacturing Co., Ltd.
Taiwan integrated circuit manufacturing Co., Ltd., Chinese abbreviation: TSMC, English abbreviation: TSMC, belongs to semiconctor manufacturing company. Founded in 1987, it is the world's first professional integrated circuit manufacturing service (wafer foundry) enterprise. Its headquarters and main factories are located in the Science Park of Hsinchu City, Taiwan Province, China
in 2017, the market share was 56%. In the first quarter of 2018, the combined revenue was US $8.5 billion, a year-on-year increase of 6%, the net profit was US $3 billion, a year-on-year increase of 2.5%, the gross profit rate was 50.3%, and the net profit rate was 36.2%, of which the 10 nanometer wafer shipment accounted for 19% of the total wafer revenue. As of April 19, 2018, TSM has a market value of US $217.4 billion and a static P / E ratio of 19
on July 16, 2020, at the TSMC's second quarter performance presentation meeting, the spokesperson disclosed at the meeting that he did not plan to continue to supply goods for Huawei Technology Co., Ltd. after September 14. The new regulations on Huawei announced by the US government on May 15 will take effect on September 15. On July 13, 2020, Taiwan media juheng.com reported that TSMC had submitted an opinion to the US government, hoping to continue to supply Huawei after the 120 day grace period of Huawei's ban expired
On December 27, the reporter learned that the Zhuzhou intermediate people's court recently held a public court session to pronounce a sentence on the second instance of the case in which 35 people, including Duan, organized and led pyramid selling activities. It is reported that this is an online pyramid selling case involving many provinces and cities in China, involving more than 1.6 billion yuan
According to the relevant laws and regulations and the role of Appellants in the crime process, the court of second instance allowed the appellant Ding to withdraw the appeal, rejected the appeals of the Appellants Zhang and Liu, maintained the conviction and sentencing of 26 people such as song and Yang, maintained the conviction of 5 people such as Yi and Li, and revoked Yi and Liu For the sentencing part of the five persons, Li and Duan were sentenced to imprisonment ranging from 4 years to 10 months, and fined from 1.5 million yuan to 50000 yuan. At the same time, they were ordered to recover and turn over the seized money and goods to the state treasuryblockchain
features
we can compare the development of blockchain with the development of the Internet itself. In the future, something called finance Internet will be formed on the Internet. This thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chain and instry chain (LAN), Bitcoin series start from the public chain (WAN), all express the same concept - digital asset, and finally converge to an intermediate equilibrium point
the evolution mode of blockchain is as follows:
blockchain 1.0 - digital currency
blockchain 2.0 - digital assets and smart contracts
blockchain 3.0 - Dao, DAC (blockchain self-consistent organization, blockchain self-consistent company) - & gt; Blockchain Society (Science, medical, ecation, etc., blockchain + AI). At present, classified editing blockchain is divided into three categories, among which hybrid blockchain and private blockchain can be regarded as generalized private chain:
public blockchain
public blockchain means that any indivial or group in the world can send transactions, and transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is the earliest blockchain, and it is also the most widely used blockchain at present. The virtual digital currencies of bitcoin series are all based on public blockchain, and there is only one corresponding blockchain in the world
consortium blockchains
instry blockchains: multiple preselected nodes are designated as bookkeepers within a certain group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process). Other access nodes can participate in transactions, but not the bookkeeping process (essentially, trusteeship bookkeeping), It just becomes distributed accounting, the number of preselected nodes, how to determine the bookkeeper of each block to become the main risk point of the blockchain), and anyone else
it will lose
