computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second
in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow
computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value
therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world

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<

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.

on May 3, 2017, a big news in science and technology circles: the world's first optical quantum computer surpassing the early classical computer was born. This "world's first" is a genuine "made in China" and is the result of a breakthrough made by Professor Pan Jianwei and his colleagues of the University of science and technology of China and Professor Wang Haohua of Zhejiang University
if the speed of traditional computer is bicycle, the speed of quantum computer is just like airplane. In the past few months, IBM and Intel have announced that they have built 50 and 49 qubit quantum computers, respectively. Some experts point out that within ten years, the computing power of quantum computer may catch up with and surpass the current supercomputer
at the American Physics Annual Meeting held in Los Angeles on March 5, 2018, Julian Kelly, a research scientist at Google quantum AI laboratory, reported that he was leading the Google team to test a 72 qubit universal quantum computer. However, this is only 72 qubits. At this rate of development, the magic power of quantum computer will soon be terrifying
then, why do we say that quantum computers can easily crack bitcoin? What's the matter
it takes 600000 years to crack an RSA cryptosystem, but it takes less than three hours to use a quantum computer with considerable storage function! In other words, with the leap from electronic computer to quantum computer, the computing power and the ability to process big data of the whole mankind will be improved for tens of thousands or even hundreds of millions of times. In front of the quantum computer, the traditional electronic computer we used to be proud of is equivalent to the previous abacus, which is bulky and old
although the bitcoin protocol uses asymmetric cryptocurrency, the corresponding public key is used to verify the transactions signed by the private key to ensure that bitcoin can only be used by legitimate owners. It is not feasible to force the private key to be consistent with the public key by using the currently available computer, but quantum computer can solve the problem of asymmetric cryptocurrency
in addition, the rule of bitcoin is that the more processed block will be added to the blockchain, and the other block will be voided. For example, it's like 51 people in an account book say that you have saved 100 yuan in the bank, while 49 people say that you have saved 50 yuan. In this case, the minority of blockchain algorithm is subordinate to the majority, and the bank thinks that you have saved 100 yuan is true, and that you have saved 50 yuan is false. So once a miner has 51% of the computing power, other subsequent miners will not be able to continue to get bitcoin
Andersen Cheng, co-founder of a network security company in the UK, says bitcoin will come to an end the day quantum computers come into use. What's your opinion?
everyone wants to buy this graphics card with high cost performance and strong performance, but the current proction and shipment volume is relatively small, so they can't buy it.
for i510400f, choose a graphics card of about 1500 yuan, such as ASUS or MSI,
the motherboards of these two brands are worth buying and trustworthy!
you can make do with it now, but the performance of gtx1060 is also good, and mainstream games can run smoothly
it's not a good time to buy a graphics card.
The eight trigrams array belongs to strong defense. If you want to break the eight trigrams, you should first know how to make eight trigrams. The eight trigrams is to use horse steps, and then you just need to seize the eight trigrams of your opponent
as for what some people say, the eight trigrams array is useless and will die when someone tramples on it, others don't think so. They say that the eight trigrams array is the strongest defense and will never die when someone tramples on it. As for the fact that other people can easily break the array, it shows that his chess power is stronger
when you want to defend, if there are eight trigrams for you to play, you should play on the eight trigrams
breaking method: occupy the nodes of the enemy's eight trigrams array, and make the enemy's eight trigrams net fail

gobang rules:
(1) each side of the game holds one color of chess pieces
(2) empty chessboard starts
(3) black first, white then, alternate, each time can only next son
(4) the chess pieces are placed on the blank points of the chessboard. After the chess pieces are placed, they shall not move to other points. They shall not be removed from the chessboard or picked up to fall elsewhere
(5) the first piece of the black side can be placed on any cross point of the chessboard
(6) it's the right of both parties to take turns, but any party is allowed to give up the right (i.e. pass right)
Gobang match, the implementation of black designated start, three hands can be exchanged, five hands two play rules. During the whole match, the black side has no hands, but the white side has no hands. There are three kinds of black hand ban: three or three hand ban, four or four hand ban and long company hand ban
Generally speaking, compression cracking software is solved by computing power, that is, one by one try password
so compression cracking software is basically the same, if there is a difference, in fact, it does not support GPU cracking or CPU cracking code optimization
of course, there is no way, you can try to bypass directly
compression files have a MD5 value, In fact, you can think of it as the hash code of a file
the MD5 value of a compressed file with and without a password will be different
the MD5 value of a compressed file with different passwords will be different (key)
since the MD5 value of different passwords will be different, Then you can use the similar hash decoding to decode the password
so as to save a lot of time
MD5 value actually exists in every windows file
its role is to check whether the file has been maliciously modified
