What unit is blockchain exchange M

1. blockchain is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chained data structure, which is composed of data blocks connected in sequence according to the time sequence, and is a distributed account that can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
blockchain and big blockchain are not the same concept. Big blockchain should be the name of a company. Bitcoin, Ethereum and decent are all successful cases of blockchain technology.

In the numeral unit, K and m are the letter forms of the unit of calculation. K stands for thousands and m for megabytes

k and m are the kilogram and megagram used to constitute the decimal multiple in the national legal unit of measurement respectively

k = 1000 = 10 ^ 3, which means thousand

m = 1000, k = 1000000, M = 10 ^ 6, indicating megabytes (1000 & # 178;)

extended data:

the counting units are in the order of indivial, ten, hundred, thousand, ten thousand, one hundred thousand, one million, one hundred billion, one hundred billion, one hundred billion, one trillion, ten trillion, one hundred trillion, one thousand, ten thousand, one hundred, one thousand, ten thousand, ten thousand, one hundred thousand, one thousand, ten thousand, one hundred, one thousand, one thousand, ten thousand, ten thousand, ten thousand, ten thousand, ten thousand, ten thousand, one hundred, one thousand

For example, 7000 can be written as 7K, 1000 can be written as 1K, 70000 can be written as 70K and so on. From the right end, the first is "indivial", the second is "ten", the third is "hundred", the fourth is "thousand", the fifth is "ten thousand", and so on

The characteristic of the decimal counting method is "one after ten". That is to say, every 10 units constitute a higher unit adjacent to it. That is to say, 10 ones are called "ten", 10 tens are called "hundred", 10 hundred are called "thousand", 10 thousand are called "ten thousand"

3. Since September 4, 2017, the people's Bank of China and other seven ministries and commissions have jointly announced that ICO has been defined as "illegal financial activity" and all blockchain exchanges in China have been closed. At present, it is illegal to say that it is in China. Xt.com exchange is headquartered in Hong Kong, which is fully compliant and legal.

A single exchange domain name is worth tens of millions

4. Millon.

$708 is about 49.56 billion yuan,

$is the symbol of US dollar, so it is calculated according to the exchange rate between China and the United States, and then multiplied by 1 million yuan

5. At present, the Chinese government has not recognized the legal status of digital currency. In September 2017, the central bank, China Banking Regulatory Commission and other official departments issued documents to prohibit the trading and circulation of digital currency (token, virtual currency) in China. Therefore, the so-called "digital currency" represented by bitcoin is illegal and must not be invested. Blockchain technology is only a scientific means. If someone uses blockchain to carry out illegal fund-raising and other criminal activities, it will be subject to legal sanctions. From the current situation, almost all the investment projects under the banner of "blockchain" are in the gray area. They are often suspected of fraud, illegal fund-raising and other illegal and criminal activities. We must be vigilant and not be confused by the clever words of illegal companies and personnel.

6. M
in English, it should be the abbreviation of million
$780m
is 780 million US dollars = 780 million US dollars
according to 1 US dollar = 7.57 RMB

590 million?

M is the symbol of length unit "meter"

In the international system of units, the standard unit of length is & quot; Rice;, With the symbol & quot; m" express. These length units are all metric units. A centimeter is one percent of a meter. Length unit, symbol: cm.

symbol of length unit:

international unit is & quot; Rice & quot Symbol & quot; m")， Commonly used units are millimeter (mm), centimeter (CM), decimeter (DM), kilometer (km), meter (m), micron μ m) Nano (nm) and so on

extended data

the origin of one meter

& quot; Rice & quot; The definition of "the world's largest economy" originated in France. The length of 1 meter was initially defined as one millionth of the distance from the earth's equator to the north pole on the meridian line passing through Paris, and then the international meter prototype was determined. With the deepening of people's understanding of weights and measures, the definition of meter length has been revised several times

Since 1983, the length of meter has been defined as & quot; The distance light travels in vacuum in 1 / 299 792 458 seconds

2. Conversion of length unit

1km = 1000m

1m = 10decimeter

1m = 10cm

1m = 100cm

1cm = 10mm

8. M should mean rice
