Extended information:
Price-to-book ratio: refers to the ratio of stock price per share to net assets per share. The price-to-book ratio can be used for investment analysis. Generally speaking, stocks with a lower price-to-book ratio have higher investment value. On the contrary, stocks with lower investment value.
Opening price: 9:15-9:25 am is the call auction time. During the call auction period, the exchange's automatic matching system only stores but does not match. When the application bidding time ends, the matching system will based on the call auction. In principle, the opening price of the stock on that day is generated. According to the regulations of the Shanghai Stock Exchange, if there is no transaction of a certain security within half an hour after the market opens, the closing price of the previous day will be the opening price of the day. Sometimes there is no transaction for a certain security for several consecutive days. The stock exchange will put forward a guide price based on the price trend of the customer's order for buying and selling the security, and then it will be used as the opening price after the transaction is completed. The average price or average offering price of securities traded over the counter on the day before listing on the first day of listing is the opening price.
Close: The closing price refers to the transaction price of the last transaction of a certain security before the end of one day's trading activities on the stock exchange. If there is no transaction on that day, the last transaction price will be used as the closing price, because the closing price is the standard for the current day's market and the basis for the opening price of the next trading day, which can be used to predict future securities market conditions; therefore, investors are optimistic about the market situation. When analyzing, the closing price is generally used as the basis for calculation.
Trading: It means that investors do not actively buy and sell, but adopt a wait-and-see attitude, causing the stock price to change very little on the day. This situation is called trading.
Consolidation: It means that after a period of sharp rise or fall, the stock price begins to fluctuate slightly and enters a stage of stable change. This phenomenon is called consolidation, and consolidation is the preparation stage for the next big change. Panjian The stock price rises slowly, which is called Panjian. A slow decline in the stock price is called a soft market. Retracement refers to the phenomenon that during the rising process of stock price, it temporarily falls back due to excessive rise. The number of transactions refers to the number of transactions of various stocks on the day. Trading volume refers to the total price of each stock traded on the day. The last bid price refers to the price that buyers want to buy after the market closes that day. The last bid price refers to the seller's asking price after the market closes that day.

The technology Very powerful, the transaction speed of 3 seconds is the bestThe fastest ball, you can go to the official website to learn more and read the white paper. It is my honor to take my advice, thank you, and wish you a happy life!

Ⅲ What are the blockchain companies?

As follows:

Currently almost all Internet companies are starting to work on blockchain. Most traditional financial companies are involved. There are serious pure blockchain companies that do some technology research and development, including Yunxiang, Qulian, and Taiyi; there are also companies that do public chain main chains, such as Xunlei, Xiaoyi, Byuan, etc.

There are also many companies that are actually working on blockchain technology, such as Qulian Technology, Wanxiang Blockchain, Energy Chain Group, Complex Beauty Technology, Galaxy Blockchain, Zhigui Technology, and Medical Chain The groups are all well-known companies in the industry with good technology. Internet giants basically have blockchain sections.

More than 10,000 new blockchain companies will be added in 2020

Despite the COVID-19 pandemic, China’s blockchain industry is still growing significantly. As of July 2020, more than 10,000 new blockchain companies have been established in China. The number of new companies in 2020 exceeded the 18,500 in 2019.

The continuous influx of new blockchain companies has laid the foundation for the development of my country's blockchain industry. However, due to the rapid development of the blockchain industry, there is a shortage of professional talents to match it, and most employers will face the problem of recruiting people.

IV What are the three major public chains of blockchain?

The three major public chains of blockchain refer to BTC, ETH, and ADA
Blockchain public chains are also called It is a public chain of blockchain. The public chain means that anyone can read the data in the system at any time. Public chains are often completely decentralized. This feature makes it impossible for everyone and institutions to control or It is tampering with the data on the chain.
Extended information:
Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
Types
1. Public Blockchains
Public Block Chains means: any individual or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain , anyone can participate in its consensus process. The public blockchain is the earliest blockchain and the most widely used blockchain. The virtual digital currencies of all major bitcoins series are based on the public blockchain. There is only one blockchain corresponding to this currency in the world. .
2. Consortium (Industry) Blockchains
Industry Blockchains (Consortium Block Chains): Multiple preselected nodes are designated within a certain group as bookkeepers, and each block is generated by all preselected nodes. FestivalPoints jointly decide (pre-selected nodes participate in the consensus process), other access nodes can participate in transactions, but do not participate in the accounting process (essentially still managed accounting, but become distributed accounting, how many pre-selected nodes, how to decide each The bookkeeper of the block becomes the main risk point of the blockchain), and anyone else can conduct limited queries through the open API of the blockchain.
3. Private Blockchain
Private Block Chains: Only use the general ledger technology of the blockchain for accounting. It can be a company or an individual, and the blockchain can be used exclusively With write permissions, this chain is not much different from other distributed storage solutions. Traditional finance is trying to experiment with private blockchains, while applications of public blockchains such as Bitcoin have been industrialized, and application products of private blockchains are still being explored.

IV What are the large-scale domestic blockchain companies?

The large-scale domestic blockchain companies include Xinchen Technology, Yinjiang Shares, Cultural Great Wall, Radio and Television Express, Hundsun Electronics, etc. .

VI How many public chains are there in China at present?

There are three major public chains in China: NEO, Qtum, and LCC digital chain.

NEO Xiaoyi:

NEO Xiaoyi was founded in 2014 and open sourced on github in June 2015. The characteristic of the NEO public chain is that it can pass through the peer-to-peer networkA series of technical combinations such as network, Byzantine fault tolerance, digital certificates, and smart contracts can make blockchain applications more secure and efficient.

Qtum Quantum Chain:

Quantum Chain is a contract hub established through the collaboration of partners and third parties, and is suitable for various industries. The development of business smart contracts is standardized, including converting natural language contracts into machine-readable smart contracts, with a high fault tolerance rate. For third parties, the assistance of Quantum Chain can be used to complete the docking with users.

LCC Digital Chain:

Launched in November 2017

Compared with the other two public chains, both the growth rate and the market value are huge. There is room for growth, and there are the following points that are optimistic about LCC:

1. The digital chain adopts a pure POW mechanism, which is fairer, more mechanical and more decentralized than POS.

2. Smart contracts, superconducting consensus, nano-nodes

3. It is the easiest to get started in the current public chain with the lowest threshold. Any computer can participate in the network, and a true universal community can be realized. Blockchain.

4. Applications are constantly being implemented: block chess and cards, block cities, etc.

In the digital cryptocurrency market headed by Bitcoin, there is a kind of public chain basic smart contract. Strictly speaking, the current Bitcoin is also a public chain, followed by the most famous Ethereum. These have been tested by the market for several years and can still occupy the first and second place in the digital currency market value rankings. the existence of names.

If you have to focus on the domestic public chain, around 2016, with the rise of Ethereum, many domestic copycat digital currencies began to enter the public chain in the name of blockchain. The chain started smart contracts. At that time, the three most popular chains were basically NEO Ant, Quantum QTUM, and ONT. During the Bitcoin bull market cycle in 2017, these three were hailed as the most promising domestic public chains to surpass Ethereum.

However, according to the current market value, we have also seen that Ant NEO, ranked 23rd, and Quantum QTUM, ranked 63rd, have basically been classified as altcoins. This is especially true for Ontology ranked outside the 80th place. Therefore, we can see that in the smart contract market, digital currencies that are committed to public chains are basically Ethereum and Bitcoin, which are the leaders.

So don’t get hung up on domestic or foreign digital currencies, because the virtual encrypted digital currency market itself, headed by Bitcoin, has no national boundaries. It exists. The entire Internet market relies on the entire market node to operate normally.

MGS, which is quite popular recently

GOSCHAIN ​​(Guojin Public Chain)

Guojin Public Chain is a brand-new blockchain architecture, positioned as an easy-to-use, high-performance blockchain platform, aiming to achieve the performance of distributed applications Scale to meet real needs in the real world.

The industry has entered the era of "internal driving force".

GMPC hybrid chain, the most powerful technology and ecology

Xiaoyi, Ontology, Bytom,

GKC is very good

Is Quark qki a public chain?

That’s it, please give it enough time.

The most powerful public chain is undoubtedly Conflux. Its performance and consensus are world-class. Under the will of the country’s independent and controllable country, it will definitely become the number one domestic blockchain public chain. However, he is currently If there is no public offering, no coins are issued, there is no way to speculate. (However, as an important part of the blockchain economic experiment and to impact the world-class public chain, in fact, I personally think that it is very necessary for its token to be circulated on online exchanges in order to expand its influence and attract more developers. Only by prospering the ecosystem together with developers and users can there be a way out; otherwise, at most there will be a market on the big B side)

Next is NervOS, then TRON, ont, qtum, true, iris, qkc, Thunder Chain, etc., the tokens of these chains have been uploadedOnline major exchanges, with good liquidity.

Ⅶ What are the good blockchain projects in China

There are still many excellent blockchain projects in China. It is generally believed that the three major domestic public chains are Quantum, Xiaoyi and Gongxin Bao, which is the so-called "three domestic treasures: Quantum, Xiaoyi and Gongxin Bao". If you are investing, I suggest you pay attention to GXChain, one of the three major domestic public chains. GXChain is a chain that serves the global data economy. The basic chain aims to create a value network of trusted data. It aims to provide data transaction/exchange services between enterprises, between individuals, and between enterprises and individuals, while creating an entrance to the blockchain world for global users and supporting developers around the world to develop rich regional blockchain applications.
