Background: the financial application of blockchain technology brings high investment value

2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles

1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:

in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost

2. Why can blockchain solve the above pain points:

blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs

3. The application of blockchain technology in the financial field mainly includes the following aspects:

digital currency

among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits

Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost

③ digital bills

④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost

The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology

4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points

in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it

Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall)

In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreement

bitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain

based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network

2. Master node network

the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

2. Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form
China: actively and steadily promote the implementation of the research on the central bank's digital currency
as early as 2014, the central bank set up a special research group on the issue of legal digital currency to demonstrate the feasibility of the central bank's issue of legal digital currency< On October 28, 2019, Huang Qifan, vice president of China Center for international economic exchange, said: "the people's Bank of China has studied DC / EP for five or six years, and I think it has become mature. The people's Bank of China is likely to be the first central bank in the world to launch a digital currency. "
on November 28, fan Yifei, vice governor of the people's Bank of China, said at the forum that at present, the central bank's legal digital currency DC / EP has basically completed the top-level design, standard formulation, function research and development, joint debugging and testing under the premise of adhering to double-layer delivery, M0 substitution and controllable anonymity. In the next step, we will follow the principle of steady, safe and controllable, reasonably select the pilot verification area, scene and service scope, continuously optimize and enrich the DC / EP functions, and steadily promote the introction and application of digital legal tender< European Central Bank: exploring the form and possibility of CBDC. 'we are analyzing what form CBDC may take in order to achieve its potential purpose and mitigate its potential negative impact on monetary stability and financial intermediation,' Mr. kindos said. On the stable coin, Mr jindos said that it was very uncertain whether the stable coin could deliver on its promise, and it was clear that it could bring risks to consumers and the financial system. So it is understandable that authorities around the world are calling for regulatory stability.
3. The difficulty of cracking the sha256 bit encryption used in bitcoin lies not in the computer, but in the energy required. I remember someone calculated that even if you build an ideal computer without any loss of heat and resistance, you can't break sha256 before exhausting the energy of the whole solar system. Of course, although the key itself is reliable, it can't prevent hackers from stealing the key and brutally cracking the password, because the password of ordinary people is far less than 256 bits
4. The environmental protection concepts and methods of the same environmental protection units and organizations are very different, and the things that need environmental protection volunteers to do are also very different. Some environmental protection organizations engage in environmental ecation, they need volunteers to engage in publicity, websites and so on; Some environmental protection organizations engage in environmental life, they need volunteers to participate in bird watching, garbage collection, recycling of waste batteries and so on; Some environmental protection organizations are engaged in environmental protection activities. They organize volunteers to plant trees and grass seeds; Some environmental protection organizations are engaged in environmental monitoring and protection, and will organize volunteers to report pollution sources and fight against pollution units; Some environmental protection organizations are nature reserves. They organize volunteers to do environmental surveys, observe data, and publicize; Some organizations promote environmental protection procts, and ask volunteers to promote biogas digesters, firewood saving stoves, and so on.
5. GuoDun blockchain trading center is the only pilot unit of general points application issued by the Ministry of instry and information technology
6. The gold coin has appreciated.

I believe we all know that "the central bank is promoting digital currency"? what is it? In fact, digital currency is an alternative currency in the form of electronic currency, which can be used as a real transaction of goods and services. For Chinese consumers, mobile payment has long been integrated into our daily life. Therefore, the introction of digital currency is more catering to the society. We don't have to worry about its impact on our daily life. In fact, the functions and properties of digital currency are exactly the same as paper money. This means that digital currency can replace cash, which is a kind of digital RMB cash

the introction of digital currency has many advantages. Moreover, with the progress and development of the times, Chinese people can quickly accept digital currency. For the elderly, the use of digital currency is much more convenient and easy to learn, because they can pay without network and signal

now some banks have quietly launched tests, which shows that the central bank attaches great importance to the comprehensive promotion of digital currency! But when the digital currency is online, the market of payment software such as Alipay and WeChat will be compressed. So, are you looking forward to this new way of payment< br />
