Is Pubang a blockchain

3.

Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:

1, open source code

upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public

2, complete decentralization

anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"

3. Developing decentralized applications

through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

5. Blockchain application will be the first to start in the financial field with high credit cost. The corresponding investment field involves cross-border payment, and the securities issuance and trading system and insurance instry may benefit first. Relevant concept stocks are as follows, for reference only:
Hengbao stock: big data security analysis
Radio and television express: digital currency, blockchain research
Westone: distributed encryption
WINTIME: blockchain technology reserve, But out of the initial stage
gaoweida: application of blockchain bills
Changliang Technology: it service provider of distributed core system of Weizhong bank
Tianji Technology: distributed storage
Wanxiang Qianchao: large shareholder Wanxiang Group establishes blockchain laboratory
Xinya Da: following the application of blockchain and other technologies in the financial instry
Yuanying China: a digital currency crowdfunding company This is the first time.

Blockchain is a new application mode of distributed data storage, which is an important concept of bitcoin. At present, there are 35 stocks associated with the blockchain concept in the A-share market, of which 6 blockchain concept listed companies are traded on the Shanghai Stock Exchange, and 29 blockchain concept listed companies are traded on the Shenzhen Stock Exchange

according to the correlation of blockchain, the leading stocks of blockchain concept stocks are most likely to be born from Xinchen technology, luyitong and Sifang Jingchuang

Xinchen Technology: on September 29, 2016, the company said in the interaction that the company is now doing research and development of blockchain technology

Lu Yitong: the company plans to raise 67.9691 million shares of additional shares of RMB 24.57 per share, and the total amount of supporting funds will not exceed RMB 1.670 billion, which will be used to pay the cash consideration of this transaction, construct the block chain ASIC chip instrialization project, artificial intelligence ASIC chip R & D center, chip proct marketing and service network, etc

Sifang Jingchuang: on May 31, 2016, the inaugural meeting and the first general meeting of the financial blockchain cooperation alliance (Shenzhen) was officially held in Shenzhen Wuzhou Hotel, and the company was one of the members of the meeting

Blockchain listed companies include Yiqiao (002447), Yijian (600093), Sifang Jingchuang (300468), Feitian Chengxin (300386), xinguo (300130), etc. Please see the chart for the rest:

8. Introction: the company is a joint-stock company established by Guangzhou Pubang garden supporting Engineering Co., Ltd. On August 5, 2010, the company received it from Guangzhou Administration for Instry and commerce.

9. You and I know that people are hypocritical and the stock is controlled by people. After checking, the market information shows that the stock needs to introce major investors, which should be good. The information shows that the stock is suspended for a short time. You and I can see where the market is when the stock is suspended. If you know something, you can see whether this point is enough to support it. Then why should the stock be suspended here, Combined with the stock market trend and the stop of the wedge point, I think the stock will be in the long run, the long-term bottom has appeared, remember that it is a long-term, after the opening, there is a make-up drop, you can also buy more and more

10. PPP (public private partnership) is a kind of project financing mode in public infrastructure. In this mode, private enterprises and private capital are encouraged to cooperate with the government to participate in the construction of public infrastructure. PPP mode has the following advantages. Combined with these advantages, we can understand why we should strengthen the promotion. 1. To avoid cost overrun, private organizations participate in government infrastructure, which means that they can participate in the construction of projects together and supervise each other. And PPP mode can only be used when the project is completed and approved by the government. PPP mode is concive to improve the efficiency of project construction and rece project cost, but also to avoid the risk of project funds. 2. To rece the financial burden, PPP mode can make the government avoid heavy business and have more time to supervise the implementation of basic projects, which not only ensures the quality of projects, but also reces the government budget. 3. The PPP mode of mutual benefit and win-win can make the government and private organizations learn from each other, play their own advantages and make up for each other's shortcomings. Both sides can form a mutually beneficial and win-win situation. 4. Reasonable risk allocation PPP realizes reasonable risk allocation at the initial stage of the project, and the government shares part of the risk. So as to rece the risk of contractors and investors, and also rece the difficulty of project financing. It means that the investment risk of PPP projects is shared by the government.
