Application of blockchain technology in stock trading
From the perspective of technology and architecture, I will tell you my understanding of blockchain in common language
what is blockchain? In a word, blockchain is a storage system. To be more specific, blockchain is a distributed storage system without an administrator and each node has all the data
What are the common storage systems like
as shown in the figure above, the bottom is data, and the top can write data. A space to store data, a software to manage data, provide an interface to write data, this is the storage system. For example, MySQL is the most common storage system
What are the problems of ordinary storage system? There are at least two common problems
the first is the problem of non high availability. There is a dangerous place for data. In technical terms, data is not highly available
The second problem is that there is only one write point. In technical terms, it is a single point of control
How do ordinary storage systems usually solve these two problems
in fact, MySQL can do a master-slave synchronization of al master, master-slave synchronization of al master, two nodes can be written at the same time. If you want to do a multi room multi live data center, in fact, multi room multi live data synchronization. What we should emphasize here is that multi-point writing often leads to the consistency problem of writing conflicts. Take MySQL as an example, suppose that the attribute of a table is self incrementing ID, then the data in the database is 1234 now. If one of the nodes writes and inserts a piece of data, it may become 5, and then these 5 pieces of data are synchronized to another master node, Before synchronization, if another write node inserts a piece of data, a piece of data with self incrementing ID of 5 will be generated. Then, after the generation, synchronize to another node, and the synchronized data will conflict with the two local 5's after it arrives, which will lead to synchronization failure and write consistency conflict. This problem will occur in the case of multi-point writing
how to ensure consistency in multi-point writing

A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare
First, in the field of finance,
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields
Second, the Internet of things and logisticsblockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management
Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs Sixth, the data stored on the public welfare fieldblockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision
as we all know, bitcoin can realize point-to-point value transmission. In addition to bitcoin blockchain, there are many other blockchains, such as Ethereum blockchain. Therefore, we should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology
blockchain, which is first accompanied by the emergence of digital currency, has recently been widely discussed in the instry for its subversive impact on the existing financial field, and is known as a new round of change after the Internet technology revolution. As a distributed general ledger, this technology will first break out a huge force of change in the financial field: clearing, settlement, remittance, payment, value transmission, innovation and inclusive of the whole financial network, including all income groups, connecting regions and people separated by physical borders, and reshaping the whole economy and society
because blockchain is an open, transparent, traceable and tamper proof distributed general ledger system, blockchain technology can effectively rece the error rate of payment, clearing and settlement steps, and monitor the inflow and outflow of funds in each step, which is an effective means to promote the establishment of an honest society. Therefore, if the regulatory authorities can effectively use this technology, it will help to control the asset status and possible risks of the financial instry
China's blockchain enterprises continue to emerge
since 2015, China's attention and Research on blockchain technology has graally expanded
from the perspective of government departments, Zhou Xiaochuan, governor of the central bank, pointed out in February 2016 that digital currency must be issued by the central bank, and blockchain is an optional technology. Prior to that, the people's Bank of China also held a seminar on digital currency. In addition to the central bank, Zhejiang Province, Beijing and other relevant government departments also expressed their support for blockchain application research last year
from the perspective of enterprises, Wanxiang Group has established a blockchain laboratory, and many blockchain innovation and entrepreneurship enterprises continue to emerge< In addition, a number of instry alliances are being established. In December 2015, blockchain research alliance and blockchain Application Research Center were established; In February 2016, Zhongguancun blockchain instry alliance was established; In April, China ledger officially announced its establishment in Beijing<
blockchain concept stocks become the wind outlet
blockchain is like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry. According to the survey report of the world economic forum, it is predicted that by 2025, 10% of the relevant information in the global GDP will be preserved by blockchain technology. Blockchain technology is facing a blue ocean, and related concept stocks are becoming the wind. In A-share listed companies, it is suggested to focus on the concept leading stocks: Feitian integrity, Yuyin shares. In the future, with the fermentation of speculation, other concept stocks are expected to follow suit
according to the analysis of wind information, the brief comments of blockchain concept stocks are as follows:
Feitian integrity: the password technology interactive platform means to follow up the blockchain
Yu Yin Co., Ltd. is organizing a team to follow up the blockchain

based on this, blockchain technology is considered to be the core technology with the most potential to trigger the fifth round of disruptive revolution after steam engine, power, information and Internet technology.
The application of blockchain technology in the securities instry can increase the flexibility of securities issuance. Companies issuing securities can adopt smart contracts, and even issue securities 24 hours in an ideal state by setting the way and time of securities issuance
under the operation of smart contract, the buyer and the seller are automatically paired, and the settlement and clearing steps are automatically completed through the distributed digital registration system. The transaction records on the blockchain will not be changed casually, so the information entered has the effect of publicity in practice, so there will be no dispute about the confirmation of ownership in the stock exchange
in addition, blockchain technology makes the securities trading process more open and transparent. Through the blockchain technology, the securities instry does not need core institutions to operate and manage, nor does it need investment banks to underwrite, so as to achieve real point-to-point transactions, rece the illegal activities such as the black box operation and insider trading in securities trading, and realize the effective supervision of the securities instry
1. Blockchain technology can realize the automatic transaction settlement of the exchange, bypass the third party, improve the transaction speed, rece costs, rece operational risks and human errors
2. At present, blockchain technology is mainly used for post transaction clearing services, as well as equity trading management in the OTC market, rather than the mainstream exchange market. The reason is that blockchain technology needs a lot of storage space and a long confirmation time, coupled with the limitation of transaction speed, it is not suitable for centralized floor trading
3. Because of its confidentiality and unchangeable characteristics, blockchain is suitable for securities registration and can rece the registration time
4. Blockchain technology is a double-edged sword for the exchange. On the one hand, it helps the exchange rece the operating costs and risks, and on the other hand, it also reces the income of the exchange in clearing (the decrease of settlement fees and the shortening of settlement cycle will rece the interest income of the custody bank and settlement company). Therefore, for the exchange, it is necessary to develop new data services to make up for the revenue after using the blockchain
of course, blockchain will also have some positive effects on traditional instries. Blockchain has had a positive impact on crowdfunding, banking and tea collection. Puyin group launched the tea based digital currency Puyin.
