New extractors in 19 years
the biggest selling point of ant S3 miner compared with Avalon 3 miner is low power consumption. Although low power consumption is an advantage, the price is relatively higher
Avalon III chip and roasted cat III chip both adopt 28nm process technology, which is also used by domestic mainstream miner.
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
mining machine is a tool for procing and mining bitcoin
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />

because an ordinary miner on the market needs at least 30000 yuan, and a more advanced miner with less power consumption and higher mining speed needs 600000 yuan, it is very easy for buyers with the mentality of picking up a bargain to be cheated
When the Internet was just born, the amount of data on the whole network was small, so the simple and convenient transmission mode of HTTP protocol is very easy to use. However, with the development of the Internet, the amount of data on the network is increasing, and the disadvantages of HTTP protocol are graally revealed
about its concept :
1 the dependence on the server storing data is too strong
if there is a problem with the server, the data may be lost. I believe many people have experienced the phenomenon of 404 pages lost when opening a web page, which may be caused by the failure of the data server
When the amount of data required by users is too large, the burden of server transmission will be very heavy, which directly affects the transmission efficiency. If the data users need is compared to water flow, then the bandwidth is the ditch and the server is the reservoir. In a certain period of time, the flow from the reservoir to the ditch is also fixed, and the greater the demand of users, the more time cost will be spent3 at present, the Internet is very dependent on the backbone network
at present, a large number of Internet data are transmitted through the backbone network, once adverse factors occur, leading to the damage of the backbone network, it will inevitably affect the data access of users
about the second question:
enter the landmark SEG square of Huaqiangbei, and the floor is in the guide. On the 3rd to 5th floors, some merchants have put out various types of poster advertisements, and the shops are basically occupied by the merchants
