16 bit BCH computing power war

2. Bitcoin and bitcoin cash (BCH) have the same mining mechanism. Miners will choose whether to dig bitcoin or bitcoin cash according to the level of mining income. It is a normal phenomenon that bitcoin computing power increases and bitcoin cash computing power decreases
in short, it is a redistribution of computing power driven by interests.

The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

bitcoin (BTC) is the most popular digital currency in the world. The spread occurred on August 1, 2017. In a "hard fork" event, a new digital currency called bitcoin cash (BCH) was born

e to version switching, bitcoin blockchain is bifurcated into two independent blockchains. Everyone who owns bitcoin before the fork is entitled to the same amount of "bitcoin cash" tokens, similar to a dividend in a stock

bitcoin cash (BCH) is a new version of bitcoin with different configurations launched by a small number of bitcoin developers. It is a new type of blockchain asset. On August 1, 2017, the mining of bitcoin cash will begin, and each bitcoin investor will have the same amount of bitcoin cash (BCH) in his account

currency features

Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

Global Circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

exclusive ownership: private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay

cross platform Mining: users can explore the computing power of different hardware on many platforms

4. Introction: bitcoin cash is a branch of bitcoin. In order to solve the problem of long transaction time of bitcoin, at 20:20 on August 1, 2017, a small number of mining machines began to use 8m block to start mining, and the transaction confirmation speed was thousands of times faster than that of bitcoin using 1m block< Br > release time: bitcoin cash is a hard fork of bitcoin on August 1, 2017< < br > maximum supply: 21000000bch < br > current total circulation: 16959625bch < br > market volume: currently accounting for 5% of the cryptocurrency market < br > market value: $21882632910 < br > Future Prospects: bitcoin cash (BCH) is a cryptocurrency representing large blocks, which was born in August 2017. Bitcoin cash (BCH) focuses more on chain trading. Therefore, compared with bitcoin core, bitcoin cash (BCH) has the advantages of low handling charge, no congestion and irreversible transaction.

5. There are the following problems in the development of virtual currency in China:

1. Virtual currency in China is mainly a tool of speculation, and the actual application scenarios are less, but there are also some application-oriented digital currencies, such as Fuyuan coin, a business integral system in the jewelry instry, but the impact is small
2. Some criminals use bitcoin or virtual currency as a pretext for pyramid selling fraud. These pyramid selling activities are increasingly rampant, which seriously affects the development of bitcoin and other virtual currencies, and the government fails to crack down
3. China adopts a cold attitude towards virtual currency, which limits the development of bitcoin, denies its monetary attribute, and forbids financial institutions to carry out bitcoin related business
4. Virtual currency has the risk of money laundering, and anonymous transaction is easy to be used by criminals
5. The security of digital currency needs to be studied. Previously, there were many cases of platform theft in China, such as bitcoin piggy bank, biter and so on.

6. How to improve the ability of mathematical calculation

first, the improvement of the ability of calculation requires the study of hard theories and rules.
the correct operation must be based on a thorough understanding of calculation theory. The calculation theory in students' mind is clear and the rules are firmly remembered. When doing four calculation problems, it can be carried out in an orderly way. There are two mistakes in integer multiplication, 25 times 3 equals 95, 24 times 5 equals 100, which typically reflects that students do not have a thorough understanding of multiplication theory in the process of learning arithmetic, and how to deal with the number of multiplication carry is relatively vague. Furthermore, divisor is a decimal division in the two wrong cases (1). 44 divided by 1. 8 equals 8, 11. 2 divided by 0.05 equal to 22.4) also shows that the students' understanding of the law is not deep enough
to understand the meaning of the order and operation law, the operation order refers to the operation of the same level from left to right. In the formula without brackets, if there are addition, subtraction, multiplication and division, multiplication and division should be calculated first, then addition and subtraction; If you have brackets, you should first count the ones in the brackets, and then count the ones in the brackets. Primary school textbooks mainly talk about the law of exchange and combination of addition, and a property of subtraction: "subtracting the sum of two numbers from a number is equal to subtracting two addends from the number in turn." And the commutative law, associative law and distributive law of multiplication. These laws are applicable to the operation of integers, decimals and fractions at the same time, and are widely used. In the two wrong examples [327 - (27 + 75) = 375, 87 times 2 divided by 87 times 2 = 1], both show the students' wrong understanding of the calculation law and the operation law< Second, the improvement of computing power needs to pass, understand and master basic knowledge. In order to get the calculation results, students should first consider what mathematical concepts, operation laws, operation properties, operation rules and calculation formulas to use. Therefore, fully understanding and mastering these basic knowledge determines whether they have the ability of calculation. For example, if students want to have the ability to calculate four items of scores, they must first understand the meaning and nature of scores, understand and master the basic knowledge and corresponding basic skills such as general score, approximate score, the interaction between score and false score. Only when the relevant basic knowledge is explained clearly and the students really master it, the students will not make mistakes in calculation. Compared with the lower grades, the basic knowledge of the higher grades is more abundant. Therefore, we must not rush for success in teaching. We should help students start from sorting out the basic knowledge they have learned, use the transfer, and continue to deepen. For example, when teaching the addition of fractions with different denominators, first ask the students to answer the meaning of addition, and they will know that it is the operation of combining two numbers (or more numbers) into one number. Next, let the students observe and find that the fractions with different denominators and the units of fractions are different, and they can't add directly. After understanding this, they can guide the students to use the knowledge of general division to "turn differences into similarities", So the problem is transformed into the addition of fractions with the same denominator< Third, the improvement of calculation ability needs excellent oral calculation ability.

the new curriculum standard points out: "the basic and developmental nature of mathematics should be highlighted in the compulsory ecation stage." As for the ability of oral calculation, it is the basis of learning mathematics, and the level of oral calculation ability has an extremely important impact on students' basic calculation ability; The training of oral arithmetic is helpful to cultivate students' keen observation; It is helpful to cultivate students' comprehensive thinking ability; It is helpful to cultivate students' quick reaction ability; It is helpful to the cultivation of students' innovative consciousness. How to train the ability of oral arithmetic is an important subject worthy of discussion and research. Teaching practice tells us that it is very necessary to train students' oral arithmetic ability, and we should pay enough attention to it< Fourth, the improvement of computing ability needs to cultivate students' good computing habits.

to improve students' computing ability, we must pay attention to the cultivation of good computing habits< Make students form the habit of proofreading carefully

2. Students are required to see each data and operation symbol clearly, determine the operation order, and choose a reasonable operation method

3. Make students form the habit of careful calculation and standardized writing. Students are required to write neatly, with correct format, correct handwriting, no scribble, no alteration, and keep their homework neat and beautiful< 4. Make students form the habit of estimation and self-conscious checking. Give them the method of checking calculation and estimation, and take checking calculation as an important part of the calculation process to carry out strict requirements, advocating the use of estimation to check the correctness of the answers

5. Make students form the habit of mutual inspection. When a problem has been initially calculated, it can't be calculated completely. It's inevitable for students to make some mistakes in calculation, which requires students to check carefully

6. Be good at drafting.

7. It's mainly about interests. There are mainly the following types of people who oppose BCH:
1. They hype themselves and pave the way for their bifurcating bitcoin. For example, Liao Xiang, who once strongly opposed big blocks, paid big money, and they all bifurcated bitcoin
2. Misled by the core development team, the melon eaters regard the miners as a group of criminals
3. The core development group's opposition to BCH is not only a divergence of development roadmap, but also a dispute of interests. The lightning network promoted by the core development group can make the gold owners behind it profit through the lightning network.

8. It's not bad. It's 100 times more than 300 days. Unfortunately, I just made a little less money

9.

The full name of BSV is bitcoin SV; SV” It's short for Satoshi vision. Bitcoin SV provides a new all node implementation of bitcoin cash (BCH), aiming to realize the vision originally set by Satoshi Nakamoto in his bitcoin white paper. Different from other competitive bitcoin cash (BCH) implementations that compete with bitcoin to make unnecessary changes, bitcoin SV's development planning roadmap is to restore the initial agreement of Nakamoto, maintain the stability of the agreement, conct large-scale expansion, and then allow large enterprises to develop and create project activities on the basis of stable bitcoin cash (BCH){ RRRRR}
