Ethereum 110

1. Hello! According to the survey, ETH ecological mining pool is a decentralized DAPP computing power mining mode, and mining is based on Ethereum smart contract from the beginning to the end. The way to play is to download the wallet, recharge the Eth and enter the wallet. You can cast 3 eth in each round and start mining. Once 3.3 eth are g out, the system will help you cast another 30 rounds and get 9 power gains. The miner can charge up to 90 eth for 30 times in a row, and get 270 eth. This operation mode is to use high-yield gimmicks to ince retail investors to invest and build their own capital pool, so as to roll up money and run away at any time. Moreover, judging from its propaganda documents, it is equivalent to changing to MLM. At present, bit110 has received feedback from a number of users that the platform failed to collect money. The official said that it was attacked by hackers. It is very likely that the official ran away in the name of hacker attacks. Hope you investors are cautious!

bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher

Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.

different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum

at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s

the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining

compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.

from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly

The ASIC mining machine of

bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand

Eth is the Federal Institute of technology of Zurich, located in Zurich, Switzerland. It is a world-renowned top research university. For many years, it has ranked first in European universities and enjoys the reputation of "the first university in Europe". It ranks sixth in the world in the comprehensive ranking of QS World Universities in 2020

The Federal Institute of technology in Zurich was founded by the Swiss Federation in 1854 and began to teach as a technical college in 1855. Initially, it consisted of six faculties of architecture, civil engineering, mechanical engineering, chemistry and forestry, as well as an organization integrating mathematics, natural sciences, literature, social sciences and politics

the Federal Institute of technology of Zurich ranked 9th in the world in the 2016 QS World University comprehensive ranking; In 2017, QS ranked the eighth in the world; Ranked 10th in the world in the comprehensive ranking of QS World Universities in 2018; Ranked 7th in the world in the comprehensive ranking of QS World Universities in 2019; In 2020, QS ranked the sixth in the world

the development status of eth

the Swiss Federal Institute of technology was established by the Swiss Federal Government in 1855 for the needs of national instrialization, which is a Federal University. It is not only for its own development, but also for the whole country, Europe and even the world to engage in scientific research. At the beginning, the university only had civil engineering, forest science, mechanical engineering and chemistry, and then added humanities, sociology and political science

the school has 26000 teachers and students from more than 100 countries in 16 departments, and its teaching and research fields include architecture, engineering, mathematics, natural science, social science and management science. For eth, the number of students enrolled and tuition fees are not considered at all. With the support of the federal government, the college receives as much as 9.2 billion Swiss francs a year for ecation, which does not include the use of property management and new teaching facilities

the college has also received up to 3 billion Swiss francs from third-party funding and its own technology transformation. All these funds are used for school running and scientific research, or most of them are directly used for more than 20000 students and 500 professors (full-time equivalent personnel of more than 9000 person years)

Even so, ETH continues to say that it is short of money in its annual reports in recent two years, and the reason is very simple. In order to compete with other institutions (universities), our independence is the most important, so we need a long-term sustainable financial support

last year, we expanded the enrollment of 4% of the students. At present, the number of students is 156% of that ten years ago, the number of professors has increased by 23%, and the number of scientific research personnel has increased by 53%. However, the government's scientific research funding has only increased by 42%, and the available area for ecation has only increased by 7%. We are facing great challenges

However, it is not surprising in Switzerland. Due to its unique ecation system, all resources in Switzerland are concentrated in 10 universities and 2 federal polytechnics. In other words, there are only 12 universities at the level of higher ecation, and the country is not short of money, so the current situation is formed

4. Switzerland's eth:
IELTS 7-8

extended materials:

the relevant requirements of the Federal Institute of technology in Zurich:

1. The main teaching language of the undergraate courses of the Federal Institute of technology in Zurich is German (but the teaching language of indivial courses is English or French). Most of the master's courses are taught in English. In addition, some of the courses are bilingual teaching, while a few are mainly taught in German

2. The main library of the Federal Institute of technology in Zurich has a collection of over 6.9 million books, newspapers, maps and other materials, which is the largest library in Switzerland and the Swiss science and Technology Information Center [5]. The main library is responsible for maintaining the Swiss network of libraries and information centers (nebis), through which readers can borrow materials from more than 80 universities or research institutions in Switzerland

3. According to the world's four major rankings (USNEWS world university rankings, times world university rankings, QS World University Rankings, soft science world university academic rankings), the Federal Institute of technology of Zurich is the world's top 20, ranking first in the European continent for many years, and enjoys the same high reputation as MIT all over the world

6. 1) From the perspective of consensus mechanism, bed, BTC and eth are all POW consensus mechanisms
2) in terms of algorithm, the core algorithm sha256 adopted by bed and BTC has the same value attributes, but bed has established a new economic model through new technology development; Eth uses ethash algorithm
3) from the perspective of mining cost: BTC mining is becoming more and more difficult and has become an arena for mining equipment. At present, the latest 110t ant S19 Pro mining machine has adopted the latest 7Nm chip, and the price of the machine is nearly 20000 yuan. Some low computing power machines, such as the former king ant S9, can only be eliminated, resulting in a huge waste of resources; Eth uses graphics card GPU to mine, and the cost is also quite high; And bed can dig directly with the existing bitcoin miner or the obsolete bitcoin miner with low computing power, so the cost of miner is very low and the waste of resources is reced
4) from the perspective of total amount and upgrade space: the total amount of BTC is 21 million, and the current price is about ￥ 76000; The total amount of eth will reach 113 million, and the current price is about 2500 yuan; The total amount of bed and BTC is 21 million, and there is a huge space for upgrading.

7. It should be for the convenience of identification. M1 corresponds to 1, M2 corresponds to 2. This is very intuitive. It's ok if you don't set it like this. Who said it can't be a number between 1 and 254.

8. In 2020, I'm afraid we can't simply assert that "computers are faster than human brains"
when you calculate the results of a hundred complex formulas, the computer must be fast
however, if it is to analyze a voice or a picture, it is difficult for a computer to surpass human beings.

9. Virtual currency without instrial chain will certainly collapse

10. How to earn money by raising cats
on cryptokitties, you can buy virtual cats. By 17:00 Beijing time on December 6, 2017, the cheapest kitten had reached 0.037eth. Equivalent to 110 yuan per piece
then the kittens have some opinions about the generation. For example, Gen 12 indicates that it is the 12th generation, while Gen 20 indicates that it is the 20th generation. Generally speaking, the smaller the algebra, the more valuable it is. And you can make your kittens slap each other. For example, a Gen 1 kitten and a Gen 1 kitten will give birth to a Gen 2 kitten
you can sell your kittens and their offspring for money
but what if you don't have two kittens? If you only buy one kitten, you can use your kitten to have fun with other people's high-quality kittens. The fee also depends on the kittens (to be honest, this mechanism is very evil, similar to... Borrowing chickens to have children?) The quality of the proct. If your kitten is of high quality, you can also use your kitten to mate other people's kittens, and then you get Ethereum income
but kittens also have special fertility rates

every time a kitten gives birth to one generation, it will have a certain cooling time, and it can't regenerate kittens within the cooling time,
the cooling time is divided into several grades
fast: 1 minute
swift: 2 – 5 minutes
snappy: 10 – 30 minutes
brisk: 1 – 2 minutes
plodding: 4 – 8 minutes
slow: 16 – 24 minutes
sluggi Sh (lazy kitten): 2 – 4 days
catatonic (nervous kitten): 1 week
so the price of your cat also depends on its birth time
and generally speaking, the larger the algebra is, the higher the gen value is, and the slower their growth rate is
but I want to make complaints about it because CryptoKitties is too hot! Ethereum network has a little bit of a crash, the official recommended that every time you buy a cat, the minimum handling charge is 21000. 400000 fuel = 0.01eth. However, it is irritating that I raised the procere to 1.6 million fuel, which is 0.04, and Ethereum still failed. 0.04 Ethereum. That's more than 120 yuan. It's too dark.
