However, the relevant page of wbo shows that "this organization is not in consultative status with ECOSOC", which means that wbo has no affiliation with the United Nations
the above-mentioned instry insiders said that non-governmental organizations (NGOs) are non-governmental and autonomous, which means that they are independent of the government in system, and they are not part of the government system. It is unheard of for NGOs to engage in the business of license issuance and license issuance. The source said that there is a big gap with NGOs in terms of the types and contents of services provided by wbos, It's more like a government regulator
According to UN resolution 1296, if NGOs want to register in the United Nations, their members must participate in organizational activities in a democratic way, have a democratic decision-making mechanism, have arrangements of responsibility mechanism and transparency of decision-making process, And submit information on its budget and sources of funds to the United Nations According to the instry insiders, NGOs are still on the edge of the existing international system and have limited influence on major decision-making, but it is precisely because they can be registered in the United Nations that many organizations and indivials use them as endorsement toolsit is understood that as early as 2017, there was a similar NGO organization in China, named wadcc, which claimed to be an international organization at the first level of the United Nations and became the first global super sovereign third-party financial regulatory agency (NGO) under the economic and Social Council, Wadcc, like wbo, has no affiliation with the United Nations and is only registered with the UN Ministry of social economy
2. bitcoin is a kind of virtual digital currency proposed by Nakamoto in 2009. It is characterized by no centralized issuing institution and a fixed total of 21 million pieces. It is not a one-time issue and needs to be proced by miners. Due to the decentralized structure, trust needs to rely on cryptography and consensus mechanism technology to achieve
blockchain is a general technology derived from bitcoin. It implements a decentralized database model. Bitcoin can be called blockchain 1.0 because it has no concept of smart contract. The key technologies of blockchain include cryptography encryption and decryption and consensus mechanism. Blockchain is generally used to combine with specific business logic, which needs to rely on smart contract, which provides an execution mode free from human interference
the IPO of ICO originates from the concept of initial public offering (IPO) in the stock market. It is the behavior of blockchain project to issue token for the first time, raise bitcoin and solve Ethereum and other common digital currencies.

3. There are many. Zebra blockchain lp8362 has private channel
4. Bitcoin virtual currency was invented by Nakamoto (alias) in 2009
the underlying technology of blockchain bitcoin is actually that it supports the stability of bitcoin in the past eight years. You can understand it as a subversive accounting method or database, and the core is decentralization
ICO, which is essentially blockchain crowdfunding. If an enterprise does ICO, you can understand it as IPO, But the financing is not money, but virtual currency, such as 3000 bitcoins. Of course, you can choose to sell it in any country in exchange for the legal tender of a country

5. Of course,
we are doing a lot of projects, and the coin circle is beginning to warm up. Sto is well publicized, but it is much more difficult to operate in practice than 1CO. Because the nature of its birth is securities, it needs to be regulated. Sto can't replace 1CO, so do it boldly

6. In short, the current ICO is based on the currency issued by Ethereum, as long as a smart contract is established on it, and financing needs to publicize your contract address, so that others can automatically exchange your currency when they call eth. Finally, it is said that domestic ICO is prohibited
7. 1、 Basic training
from the psychological characteristics of different ages of primary school students, the basic requirements of oral arithmetic are different. Low and middle grade students mainly add one or two digits. It is better for senior students to take the one digit by two digit mental arithmetic as the basic training. The specific requirement of oral arithmetic is to multiply the number of one digit and the number of ten digits of two digits, and then add the proct of multiplying the number of one digit and the number of one digit of two digits to the three digits, and quickly say the result. In primary school, this training is a sublimation training of abstract thinking of numbers. It is very beneficial to promote the development of thinking and intelligence. This exercise can be arranged in two periods. One is to read in the morning, the other is to arrange a group at the end of homework. Each group is divided as follows: one digit is optional, corresponding to the number of one digit or ten digit in two digits. There are 18 questions in each group. Let the students write the formula first, then write the number directly after several times of oral calculation. In this way, after a period of time (generally 2-3 months), the speed and accuracy of oral calculation will be greatly improved< Second, the main form of the number of senior primary school students has changed from integer to score. In the operation of numbers, the addition of different denominators is the most time-consuming and error prone place for students, and it is also the key and difficult point of teaching and learning. How to overcome this key and difficult point? It is proved that it is correct to put the oral calculation of fraction operation on the addition of fractions with different denominators. Through analysis and inction, there are only three cases of different denominator addition (subtraction) method, and each case has its oral arithmetic law. As long as students master it, the problem will be solved
1. For two fractions, the large number in the denominator is the multiple of the decimal
for example, "1 / 12 + 1 / 3", in this case, oral arithmetic is relatively easy. The method is: the big denominator is the common denominator of two denominators. As long as the small denominator is expanded by multiple, until it is the same as the big number, the denominator is expanded by several times, and the numerator is also expanded by the same multiple, We can add the fractions with the same denominator for oral calculation: 1 / 12 + 1 / 3 = 1 / 12 + 4 / 12 = 5 / 12
2. The denominator of two fractions is coprime. This kind of situation is more difficult in form, and students are also the most headache, but it can be changed from difficult to easy: after it is divided, the common denominator is the proct of two denominators, and the numerator is the sum of the proct of the numerator of each fraction and the other denominator (if it is subtraction, it is the difference of the two procts), such as 2 / 7 + 3 / 13. The oral calculation process is: the common denominator is 7 × 13 = 91, molecule 26 (2 × 13)＋21(7 × 3) = 47, the result is 47 / 91
if the molecules of both fractions are 1, the oral calculation is faster. For example, "1 / 7 + 1 / 9", the denominator is the proct of two denominators (63), and the numerator is the sum of two denominators (16)
3. Two fractions and two denominators are neither coprime numbers nor multiples of decimals. In this case, we usually use the short division method to get the common denominator. In fact, we can also calculate the general score directly in the formula and get the result quickly. The common denominator can be obtained by enlarging the large number in the denominator. The specific method is: to double the large denominator (large number) until it is a multiple of another denominator decimal. For example, 1 / 8 + 3 / 10 expands the large number 10, 2 times, 3 times and 4 times, and compares it with the decimal 8 every time to see if it is a multiple of 8. When it is expanded to 4 times, it is a multiple of 8 (5 times), then the common denominator is 40, and the numerator is expanded by the corresponding multiple and then added (5 + 12 = 17), and the number is 17 / 40
the above three cases are also applicable to the addition and subtraction method with score< Thirdly, the content of memory training is extensive, comprehensive and comprehensive. Some common operations are often encountered in real life. Some of these operations have no specific rules of oral arithmetic and must be solved by strengthening memory training. The main contents are as follows:
1
2. The proct of the approximate value of PI 3.14 with one digit and with several common numbers 12, 15, 16 and 25
3. The denominator is the decimal value of the simplest fraction of 2, 4, 5, 8, 10, 16, 20 and 25, that is, the interaction between these fractions and decimals
the results of the above numbers, whether in daily work or in real life, are used very frequently. After mastering and remembering them, they can be transformed into abilities and proce high efficiency in calculation< Four, regular training
1. There are mainly five laws in this aspect: commutative law and associative law of addition; Commutative law, associative law and distributive law of multiplication. Among them, the multiplication distribution law is widely used and has many forms, including positive use and negative use, and the forms of integer, decimal and fraction. In the multiplication of fractions and integers, students often ignore the application of the law of distribution of multiplication, which makes the calculation complicated. Such as 2000 / 16 × 8, using the law of multiplicative distribution, the result is 1001.5, but using the general method of false fraction is time-consuming and easy to make mistakes. In addition, there are subtraction properties and quotient invariant properties< 2. Regular training. It is mainly the oral calculation method (strategy) of the square result of the two digit number of 5
3. Master some special cases. For example, in fractional subtraction, if the numerator is not enough to be subtracted after general division, and the numerator subtracted is usually larger than the numerator subtracted by 1, 2, 3 and other smaller numbers, no matter how big the denominator is, it can be directly calculated orally. For example, the difference between 12 / 7 and 6 / 7 is only 1. The difference between 12 / 7 and 6 / 7 must be 1 less than the denominator. The result is 6 / 7 without calculation. Another example is: 194 / 99-97 / 99, if the difference between the numerator and denominator is 2, the difference between the numerator and denominator is 2, and the result is 97 / 99. When the subtracted molecule is larger than the subtracted molecule by 3, 4, 5 and other smaller numbers, the result can be quickly calculated orally. Another example is the mental calculation of the proct of any two digit number and 1.5, which is two digits plus half of it< 5. Comprehensive training

2< 3. Comprehensive training of four mixed operation sequences
comprehensive training is concive to the improvement of judgment ability, reaction speed and the consolidation of oral arithmetic
of course, in order to make students master the above situations, teachers should first use them skillfully, so that they can be handy in guiding and improve the effect. At the same time, the training should be carried out persistently. It is difficult to achieve the expected effect to catch fish in three days and dry the net in two days.

8. Although the current ICO market is very chaotic and wild, the positive side is that some excellent methods for creating and evaluating ICO are emerging
however, in the coin circle, it is important to use bitcoin ICO, and then the platform will send some tokens to users. However, the price fluctuation of these tokens is very large. Now the profit possibility of this model is relatively small. Another is the European crowdfunding model. Crowdfunding projects issue tokens, which exist as asset certificates and have a fixed dividend mechanism.
