1. Generally speaking, blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer
among them, the data layer encapsulates the underlying data block and related data encryption and timestamp technologies; The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism; The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes; The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain; The application layer encapsulates various application scenarios and cases of blockchain. In this model, chain block structure based on timestamp, consensus mechanism of distributed nodes, economic incentive based on consensus computing power and flexible and programmable smart contract are the most representative innovations of blockchain technology.
2. Hello. What is a block chain

- - hope to help you, please accept if you are satisfied.
3. Currency circle: refers to the people who focus on currency speculation and even issue their own digital currency for financing. Generally speaking, blockchain project parties, exchanges and some blockchain media all belong to the currency circle
chain circle: refers to people who focus on the research and development, application or underlying protocol of blockchain. Without the technical support of the chain circle, the coin circle can not exist. In the future, the implementation of the blockchain scene will depend on the technology of the chain circle. With the popularity of blockchain technology, many related top domain names have been registered

mining circle: refers to the "miners" who focus on "mining"

currency speculation: refers to the behavior of repeatedly buying and selling digital currency through the trading platform in order to obtain high income

suoha: it's a transliteration of show hand in English. It was originally a term in gambling games. It's the act of withdrawing all the available chips in hand at one time. When it comes to blockchain investment, it refers to investing all of your available assets in digital currency in order to speculate in money, which has the meaning of "bet your fortune"

Buddhist holding of cryptocurrency: refers to the behavior of not caring about the price trend of cryptocurrency after holding of cryptocurrency, no matter how much the asset price of cryptocurrency falls, it will not rece the holding of cryptocurrency in hand.
4. Blockchain is used through investment.
5. The result of these two attacks is that the other party's system is out of service or crashed e to information overload. But DoS attack is a single server attack, while DDoS attack is distributed multiple servers attack, the success of the attack is higher. The application of blockchain technology should be more and more, so it is necessary to understand the knowledge of blockchain. It is recommended that you go to the official website of Xuanling technology. This website has many popular science and application posts of blockchain technology, which should be of great help to blockchain learning.

The center is Yuzhong District. The core of Chongqing's main urban area, especially Jiefangbei Chaotianmen business district

the main urban area of Chongqing, which is called the metropolitan area in Chongqing's urban and rural master plan, covers an administrative area of 5472.68km2, including Yuzhong District, Dakou District, Jiangbei District, Nan'an District, Shapingba District, Jiulongpo District, Beibei District, Yubei district and Banan District. Metropolitan area is the core carrier of the National Central City and the political, economic, cultural, transportation and financial center of the whole city

Yuzhong District is the mother city of Chongqing and the seat of Chongqing municipal government. Shapingba District is the cultural and ecational District of Chongqing. Beibei District was the relocation area of Chongqing ring the period of the Republic of China. It was once the seat of the Executive Yuan and the presidential palace of the Republic of China. Banan District and Yubei district were originally Ba County and Jiangbei County, which are the mother counties of Chongqing. Their status is similar to Minhang District and Baoshan District in Shanghai or Fengtai District and Tongzhou District in Beijing



extended data:

at the beginning of its establishment in 1929, Chongqing's "city" area was 2.4 square kilometers. After more than 80 years of development, Chongqing's built-up area expanded more than 200 times. By the end of 2009, the built-up area of Chongqing's main city had reached 481 square kilometers

Since 1997, e to the special structure of Chongqing, the main urban area of Chongqing, which is similar to the concept of economic and cultural transportation of the municipality directly under the central government, has been formed

this concept is often associated with "old Chongqing area" (Chongqing City, Sichuan Province, commonly known as nine districts and twelve counties) and "Chongqing Municipality" (38 districts and counties in Chongqing), 95 square kilometers)

Since Chongqing became a municipality directly under the central government for the first time in 1939, the main urban area of Chongqing was the original administrative area of Chongqing in the Republic of China, which remained until the liberation

From 1950 to 1980, Chongqing was first reced from a municipality directly under the central government to a city under separate planning, and then to a prefecture level city. Its administrative area expanded to the sum of the nine districts in the main city of Chongqing plus Changshou District, Qijiang district and Shuangqiao District (Note: Shuangqiao District was incorporated into Dazu District in 2011)

since the 1980s, the cities separately listed in Chongqing's recovery plan, Jiangjin administrative Commissioner's office of Sichuan Province and eight counties in Yongchuan area (Jiangjin County, Bishan County, Yongchuan County, Hechuan County, Tongnan County, Tongliang County, Rongchang County, Dazu County) have been merged into Chongqing and become a part of Chongqing

The status of these counties in Chongqing is similar to that of Qingpu, Chongming and Jiading in Shanghai; Baodi and Jinghai in Tianjin or Miyun and Yanqing in Beijing are similar to Huangpi in Wuhan, Lin'an and Jiande in Hangzhou, Conghua and Zengcheng in Guangzhou

8. 1. Utility token

utility token is a utility token that acts as a right to use a specific service

examples of terminology usage

utility tokens are premised on the use of services

detailed description

you can settle the price of goods and meals instead of cash, and you can access it by having cloud storage. For utility tokens, there is no need to audit the classification of the report

6, public chain

public chain is a highly "public" blockchain, anyone can freely participate in the network

example of terminology usage

as an infrastructure project for mediating data exchange between blockchains, a mechanism for data exchange on public blockchains will be established

detailed description

in the blockchain used to record the transaction information of encrypted assets (virtual currency), this is a mechanism used by an unspecified number of participants to establish transaction information by consensus without a specific management entity. It is very safe to prevent forgery of transaction information, but it requires a lot of calculation, so its disadvantage is that it takes a long time to complete the transaction when there are many participants

7. Scalability

scalability refers to the scalability of delayed transaction processing

examples of terminology usage

soaring gasoline prices highlight Ethereum's scalability issues

detailed description

e to the nature of blockchain and the limited amount of transaction data that can be written in a block, the processing is delayed. Remittances can take a long time, which can lead to higher transaction costs. bitcoin is the first cryptocurrency born, which has been considered as a special problem, but efforts to solve this problem have been implemented, such as using other technologies such as lightning network and developing new blockchain

8. Gas cost

gas cost is the (Network) transaction cost on Ethereum blockchain

examples of terminology usage

this week, on the Ethereum blockchain, although there are a small amount of remittances, there are still many cases of high natural gas bills being paid

detailed description

the gas fee of user specified amount is the secondary reward. Eth, the virtual currency, is used for payment. Since the transaction with higher cost should be dealt with first, the gas cost may increase with the increase of transaction number

9. Liquidity mining (liquidity mining)

considering the provision of liquidity (currency pair), liquidity mining is to grant governance token in addition to interest, so as to attract those who implement the rate of return balance

examples of terminology usage

detailed description

in liquidity mining, by storing specific assets in the liquidity pool and providing liquidity that traders can buy and sell, the swap fee at that time can be obtained as income. These liquidity mining originated from the largest decentralized exchange "uniswap", and many liquidity mining contracts were born, such as curve finance and balancer

10. Defi (distributed Finance)

defi (decentralized Finance) refers to the financial services or systems that use blockchain and provide without a central administrator

examples of terminology usage

since June 2020, the market of defi has developed rapidly

specify the abbreviation of "decentralized finance". The financial services offered by defi include the issuance of stable coins, lending currency and cryptocurrency exchanges. Many platforms use Ethereum blockchain

11. POS (proof of equity)

POS is a consensus algorithm, which allows you to approve and generate new block rights according to the percentage (equity) of your own virtual currency

According to vitalik buterin, co-founder of Ethereum, migrating eth's consensus algorithm from POW to POS will improve security and scalability

specify the abbreviation of

proof of interest. We can also consider the holding period of virtual currency. It was born as an alternative to the "proof of work (POW)" consensus algorithm, which requires high-performance computers to approve transactions and consumes a lot of energy. If approved, you can receive a new virtual currency as a reward

12. Dapps

DAPP is an application developed with open source blockchain

examples of terminology usage

Galaxy store, the largest Samsung Electronics app store in South Korea, has started to use Tron's blockchain to process dapps

detailed description

the abbreviation of "distributed application" is called "distributed application" in Japanese. One of the main features is that there is no centralized administrator. The most popular is Ethereum blockchain, which is developing applications such as games and decentralized exchange (DEX)

9. O is offering, which can be understood as IPO
ICO (initial coin offering). Initial token issue refers to the first time that blockchain projects issue tokens to the public, and raise mainstream cryptocurrencies such as bitcoin and Ethereum to obtain funds for project operation
IFO (initial fork offerings), which is a new token generated by bifurcating bitcoin and other mainstream cryptocurrencies
IEO (initial exchange offers) refers to the issue of token with the exchange as the core; The token skips the ICO step and goes directly to the exchange
