Progress of mining machinery

1. bitcoin mining is to use the computing power of your mining equipment to calculate mathematical problems and confirm transactions. The system will give unequal bitcoin rewards according to the amount of computing power you contribute to the whole network. Bitcoin mining has gone through three stages. In the first stage, we use CPU to mine, because there are few people mining; The second stage, we use the graphics card mining, popular point is burning graphics card mining, players began to wake up; In the third stage, professional ASIC mining machines are used for mining. Starting from Avalon's mining machines and the introction of cat roasting mining machines into the market, the computing power in this stage is surging, and the mining difficulty is increasing. In the following period, new mining machine manufacturers continue to join the mining machine instry. However, with the increase of computing power and the progress of technology, Some mining machinery manufacturers began to go bankrupt or fade out of the market. Avalon has always been active in people's field of vision and constantly launched new chips. At present, Avalon has launched three generations of mining machinery chips, and the fourth generation will soon be launched.

2. The model proposed by Nakamoto is based on ideal assumptions. Of course, many academic models are like this. When they are tested in reality, they often encounter various practical challenges. I haven't read Nakamoto's paper in detail, but speculation should not be considered.

3. Butterfly laboratory in the United States is from the United States. He prefers to evade tickets. It seems that he has been prosecuted recently. As we all know, the overall performance of the garden miner is not good, and the energy consumption of the ant miner is relatively small, but the chip is made by 55nm process technology. According to the development of current technology, it will be eliminated soon. Cat roaster used to be brilliant for a time, but with the technological progress of other mining machine manufacturers, it graally went down. In contrast, Avalon has been at the forefront of innovation. Avalon delivered the world's first ASIC miner. Avalon1 once made a noise from 8000 to 300000. Avalon's second-generation chips contributed about one third of the computing power of the whole network in January. At present, Avalon has delivered the first batch of orders for the third generation chips with 40nm process technology.

6. Hello, first of all, I declare that I really don't know what kind of mining machinery you are talking about. As for whether it is pyramid selling or not, you still need to make your own judgment. Methods: one is to find out the operation mode of the company, the other is to know the basis of judgment. The most powerful basis of judgment is of course the judicial interpretation:
1 The "Regulations on the prohibition of pyramid selling" issued by the State Council defines "pyramid selling" as: "the term" pyramid selling "in these Regulations refers to that the organizers or business operators develop their employees by calculating and paying remuneration to the developed employees on the basis of their number of directly or indirectly developed employees or sales performance, Or ask the developed person to obtain the qualification to join by paying a certain fee to seek illegal interests, disrupt economic order and affect social stability. "
2. The opinion of the Supreme People's court, the Supreme People's Procuratorate and the Ministry of public security on Several Issues concerning the application of law in handling criminal cases involving the organization and leadership of pyramid selling activities states that "in the name of business activities such as selling goods and providing services, participants are required to obtain the qualification to join by paying fees or purchasing goods and services, If there are more than 30 people participating in pyramid selling activities within the organization and the level is more than three, the organizer, the manager and the manager shall be punished Leaders should be held criminally responsible
to sum up, there are three aspects: fair fee, head pulling and rebate! Of course, with the progress of society, the routine and vest of MLM are constantly updated, but no matter how they change, they are always the same. If you are interested in more anti fraud information, you can pay attention to my "Laohan anti MLM", which will continue to update the inside routine and reveal the secret of MLM. I hope you can be more vigilant, Stay away from pyramid schemes!

Thomas Alva Edison (1847-1931) was a famous American inventor and entrepreneur
born on February 11, 1847 in a peasant family in Milan, Ohio, USA. When he was 8 years old, he went to school. After only three months of study, he had to drop out of school and go home. His mother, who was a village teacher, helped him to study by himself. At the age of 12, the family life was difficult, so they began to sell newspapers on the train. At the age of 16, they invented the automatic time transmitter, and then there were many inventions. They completed more than 2000 inventions in their lifetime. In 1928, they were awarded the US Congress gold medal. On October 18, 1931, Edison died in West Orange at the age of 84. On October 21, 1931, the lights were turned off in the United States to show his mourning. Scientific achievements

Edison is a world-famous great inventor. The invention of his life is unparalleled in the world. Edison's main contributions are as follows:
1. Edison's most important contribution in science and technology is the invention of phonograph and incandescent lamp. Today, it's hard to imagine life without electricity - unable to turn on a light, listen to a record, go to the cinema, or call someone. However, all these things we take for granted are the result of a practical invention - Thomas Edison. Before Edison, on the road, in the living room, in the factory, can only use by hand lit dim gas lamp. As night fell, factories closed. Electricity or the telephone was not invented by Edison.
