Ethernet computing power cracked
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

brief history: it was called Temasek in ancient times. Founded in the 8th century, it belongs to the Sri Lanka Dynasty in Indonesia. It was part of the kingdom of Johor in Malaya from the 18th century to the early 19th century. In 1819, the British, Stanford raffles, arrived in Singapore and contracted with the Sultan of Johor to set up a trading post. In 1824, it became a British colony, a entrepot trade port in the Far East and a major military base in Southeast Asia. It was occupied by the Japanese army in 1942. After the surrender of Japan in 1945, Britain resumed its colonial rule and was designated as a direct colony the next year. In 1946, Britain classified it as a colony directly under the central government. In June 1959, Singapore implemented internal autonomy and became an autonomous state. Britain reserved the power of national defense, foreign affairs, amending the Constitution and promulgating "emergency decrees". It was incorporated into Malaysia on September 16, 1963. On August 9, 1965, it broke away from Malaysia and established the Republic of Singapore. He became a member of the United Nations in September of the same year and joined the Commonwealth in October<
Politics: the Constitution stipulates that parliamentary republicanism shall be implemented. The president is the head of state and is elected by the whole people for a term of six years. The president appointed the majority leader of Parliament as prime minister. The president has the power to veto the government budget and public sector appointments; The exercise of the powers conferred by the internal security act and the religious harmony act, as well as the investigation of corruption cases, can be reviewed.

Economy: Singapore's traditional economy is dominated by commerce, including entrepot trade, processing export, shipping, etc. After independence, the government adhered to the policy of free economy, vigorously attracted foreign investment and developed diversified economy. Since the early 1980s, we have accelerated the development of capital intensive and high value-added emerging instries, vigorously invested in infrastructure construction, and strived to attract foreign investment with the most favorable business environment. With the manufacturing and service instries as the twin engines of economic growth, we have continuously improved the instrial structure. In the 1990s, we paid special attention to the information instry and invested in the construction of "Singapore Integrated Network" in the whole island. In order to further promote economic growth, vigorously implement the "regional economic development strategy", accelerate overseas investment, and actively carry out economic activities abroad. The economy is dominated by five major sectors: Commerce, manufacturing, construction, finance, transportation and communications. Instry mainly includes manufacturing and construction. Manufacturing procts mainly include electronic procts, chemical and chemical procts, machinery and equipment, transportation equipment, petroleum procts, oil refining and other sectors. It is the third largest oil refining center in the world. Agriculture accounts for less than 1% of the national economy, mainly including poultry raising and aquaculture. All grain is imported, and only 5% of vegetables are proced by themselves. Most of them are imported from Malaysia, China, Indonesia and Australia. Service instry is the leading instry of economic growth. Including retail and wholesale trade, hotel tourism, transportation and telecommunications, financial services, business services, etc. Tourism is one of the main sources of foreign exchange income. The main scenic spots are Sentosa Island, botanical garden, night zoo, etc. Currency name: Singapore dollar (Singapore dollar for short)
Press and publication: English newspapers include straits times, business times and Xinbao; Chinese newspapers include Lianhe morning post, Lianhe Evening Post and Xinming daily; The Malay language newspaper has the daily news; In addition, there is the Tamil daily. The radio station started broadcasting in 1936 and has been broadcasting in Malay, English, Chinese and Tamil since January 1959. Radio Singapore owns and operates 12 domestic radio stations and 3 international radio stations. Singapore TV owns and operates two channels, one broadcasting Chinese programs and the other English programs, 24 hours a day. The private TV company operates two channels, one mainly serving the Malay and Indian population, and the other mainly broadcasting sports and arts programs. In 1995, the cable TV network was opened, and users can receive TV programs from more than 30 channels and more than 10 countries. Satellite TV was launched in 1995< Foreign Affairs: Based on ASEAN, maintaining ASEAN's unity and cooperation and promoting ASEAN to play a greater role in regional affairs should be placed in an important position in diplomatic work; Facing Asia, focusing on developing cooperative relations with Asian countries, especially China, Japan, South Korea, India, etc; It pursues the policy of "balance between big powers" and actively carries out economic diplomacy
relations with China: on June 14, 1980, the agreement between the Chinese government and the Singapore government on establishing business representative offices for each other was signed in Beijing, and the business representative offices of the two countries officially opened in September of the next year. On October 3, 1990, China and New Zealand established diplomatic relations.

From the perspective of data analysis, data center is undoubtedly a "big energy consumer". The annual power consumption of a super large data center is nearly 100 million kwh. The total electricity consumption of national data centers in 2018 is 160.889 billion kwh, which is more than the total social electricity consumption of Shanghai in 2018 (156.7 billion KWH), equivalent to the annual power generation of the Three Gorges dam
Internet giants such as Microsoft, Google, Alibaba and Tencent build green and efficient data centers. As instry promoters and practitioners of green energy-saving technology, enterprises are not only based on their own business needs, but also the major social responsibilities of enterprises and the whole instry.
