1. Why blockchain has always played a huge role in the financial world

We all know that blockchain is a very important tool in the investment industry. The same investment of 10,000 yuan ten years ago will reap extraordinary returns. But at that time, I bought 10,000 yuan of Kweichow Moutai stock, and now I only hold 150,000 yuan. But if you hold 10,000 yuan in Bitcoin until now, congratulations, you have assets of over 100 million yuan. Why does blockchain always play a huge role in the financial world?

To prevent single points of failure and systemic risks, the financial industry needs to conduct audits to control financial risks. And the current regulatory intensity is gradually increasing, especially the previous financial crisis that made the threshold for controlling this platform higher. The entire financial system has increased costs in many aspects. The technology of blockchain plays a role in reducing a large number of costs in finance by preventing tampering and being transparent.

Blockchain is like our commonly used ledgers. Whoever keeps accounts has a certain reason and strength. WeChat’s ledger is kept by the large platform Tencent, and the same is done by small Internet companies. It will also have its own ledger. But in the blockchain, everyone in the system can be the owner of the ledger. If there is a change in the data when you are in charge of this ledger, the system will record the person with the best accounting and the highest efficiency, so that the entire system It will allow everyone to have a complete ledger. This is the impact of simple and abstract blockchain technology.

The best time to learn blockchain was 10 years ago and now. Cai Kangyong once said: "At the age of 18, you find it difficult to speak English, so you give up English. At the age of 28, a great job, but you have to say "I can't." "But when we return to the topic of blockchain, its value lies in whether it can change our lives. The peer-to-peer blockchain allows you to complete the payment between two countries within 5 seconds, reducing the cost of your transaction. Reduced. But the blockchain that cannot be traded twice can prevent you from being "violently evicted". The secure blockchain allows you to protect your secrets to the maximum extent, and there are no more harassing phone calls. The blockchain also It allows you to enjoy the large-scale development of the sharing economy platform. Therefore, although blockchain is not a perfect technology, as long as it can change our lives, its value, like a mobile phone, cannot be ignored.

We all know that it is the winners who change the world. These winners are Tencent, Alibaba, Google and Facebook, as well as many Internet companies that we are familiar with. While they change the world, they also bring benefits to investors. We have achieved amazing returns.

We must know that Rome was not built in a day. Similarly, the value of blockchain also needs to be explored and exerted by ourselves. Blockchain is also slow amid fluctuations and doubts. It develops slowly. And most Bitcoin holders are not able to earn the maximum income, only the real understandingThe few people who are interested in blockchain and have firm confidence in it persist until the end. Only after in-depth study and understanding of blockchain can they have their own ideas. Learning blockchain is not just about learning its operating model and concepts, but also applying it to actual work, so that it can continue to exert value in finance.

2. What is the role of blockchain in big data

[Introduction] While big data brings great opportunities to all walks of life, it also brings many challenges. . Blockchain, with its decentralization, trustlessness, high transparency and non-tampering characteristics, can provide higher security, transparency and privacy to big data. So, what are the effects of blockchain in big data?

1. Improving data quality

The essence of blockchain is to remove Centralized distributed ledger. It can also be understood as an tamper-proof, fully historical, distributed database storage technology. Therefore, blockchain technology can liberate more data. The trustworthiness, security, and non-tamperability of blockchain technology fundamentally bring about the improvement of data quality and the enhancement of data verification capabilities.

2. Dealing with the data island problem

Big data has a very serious data island problem, and a lot of data is currently inaccessible. Blockchain is expected to solve this problem. The reason why I say this is mainly because the blockchain is not only a distributed ledger, but also has the characteristics of decentralization and openness. As the maintainers of order in the financial market, regulatory organizations can also predict and analyze possible dangerous problems through the data chain in the blockchain.

3. Dealing with data leakage issues

In essence, the blockchain is actually a decentralized database. Therefore, if data from a certain node in the blockchain is If there is a change, other nodes will discover it as soon as possible, so the possibility of data leakage will be greatly reduced. Only in the form of a private key can the identity information of each node in the blockchain be successfully obtained, and only the data owner can know the private key.

4. Blockchain can protect the relevant rights and interests of data

As for the valuable data assets of individuals or organizations, they can be registered using the blockchain, and the transaction records are recorded on the entire network. Recognized, transparent and traceable. Clarifying the source, ownership, use rights and circulation path of big data assets is of great value to the sale and purchase of data assets.

5. Traceability of blockchain

Every step of data collection, transaction, circulation, and accounting analysis can be recorded on the blockchain, thus making Data quality has received unprecedented strong trust endorsement. At the same time, it also ensures the accuracy of data analysis results and the effectiveness of data mining.

The above is all the content that the editor has compiled and sent to you today on "What is the role of blockchain in big data?" I hope it will be helpful to everyone. As the saying goes, don’t fight an unprepared battle. Generally speaking, with the rise of big data,Engineers and developers with the ability to work in big data technology are very popular in applications across many industries.

3. What is the relationship between blockchain technology and the financial industry

Blockchain technology has the advantages of being difficult to tamper with and easy to trace. It can be used in identity information management, trust mechanism construction, and small business transactions. The integration of micro-enterprise credit information on the chain will play a role.

Here is an example of a bank in Nanping:

Due to the explosion of online business, the original offline signing method can no longer satisfy the bank. With the demand for rapid business changes, the digital construction of banks is urgent, but bank risk control departments have strict compliance requirements:

Is the online business data sensitive and private, and is the transmission safe?

Does electronic signature have legal effect?

Is electronic evidence admissible in court?

These concerns have become obstacles for banks to introduce electronic contracts and carry out digital transformation of their businesses.

After adopting the unique ENA active evidence collection patented technology of the "Real Hammer" trusted electronic evidence platform, a bank in Nanping used the notary office to clean the server to preserve and store the electronic data of the target system online in real time. With the issuance of certificates, the entire process of electronic data from generation, transmission to storage is recorded. Finally, the notary office issues an evidence collection and preservation report stamped with the official seal. The document is a notarized document and can be directly accepted by the court. Since the report is issued by the notary public office, it is relevant. Compared with the self-certification of third-party electronic contract platforms, it is more credible and solves the concerns of bank risk control departments in one fell swoop. The entire process is online and automated, and front-end customer operations are imperceptible.

At the same time, combined with the "real hammer" middle and back-end case-like system and outsourced execution services, the bank has achieved rapid dispute resolution in Internet business. It not only ensures the compliance and effectiveness of the electronic contract signing process, but also solves the problems of bank cases being scattered across the country, high legal travel costs, long litigation cycles, and no efficient disposal channels.

4. What is blockchain technology and how does it affect the financial and monetary system?

What is blockchain technology and how does it affect the financial and monetary system? "Cratonic Destruction and Terrestrial Biological Evolution" led by Zhou Zhonghe, an academician of the Chinese Academy of Sciences and a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, became one of the first three projects to receive this funding in 2016. He told China News Weekly that the project's funding management is relatively loose, but the problem is that this kind of project is too scarce. Although this is a model of stable support, it is still essentially a type of competition. Very strong project. Zhuang Ci also believes that the proportion of support for such projects is very small and is still targeted at a very small number of people. The competition has become increasingly fierce. "When eating barbecue in Jinzhou, 70% of people come here to drink and relieve stress. For example, the guy who came last night showed off eight bottles of Harbin beer while having barbecue. Their children earn more than 2,000 a month, which is better. The houses are only seven to eight thousand square meters. Even if the family pays for the down payment, the children will have a hard time paying off the mortgage. Not only the parents are anxious, but the children themselves are also anxious." Kaiqie Pure BBQ in JinzhouBrother Li from the store said.

5. What impact will the rise of blockchain have on the future of finance

On August 6, 2018, Cai Yi, financial industry consultant to Huawei and founder and CEO of Huaxuan Technology Mr. made a special presentation at DAGA | Blockchain & AI (Core Group), with the theme: Current Situation and Prospects of Blockchain Finance. The following text is organized based on the audio of the lecture and has been reviewed by the author.

Cai Yi: Financial industry consultant of Huawei, founder and CEO of Huaxuan Technology, founder of the shared reading club, member of the Chinese Writers Association, has been engaged in financial technology research for more than ten years, and is a senior expert in the digital transformation of banks .

Good evening everyone, I am very happy and honored to be able to share some thoughts with you here.

Let me introduce myself briefly: My name is Cai Yi. I was a writer in my youth. I wrote some books, magazines and novels in the 1990s. There was no Internet at that time. Since then, I have been engaged in informatization work in the financial industry. From financial channels to data centers, from outlets to technology, I have witnessed the development of financial technology and discovered some problems. He has been an investment partner since 2014, and has also worked as a financial industry consultant for Huawei in recent years. From a cognitive perspective, he serves as a consultant for talent development in the digital transformation of the financial industry.

I came into contact with blockchain in 2015, when I founded Huaxuan Technology and Shared Reading Club. At present, we mainly focus on the understanding of blockchain and the implementation of financial technology solutions. At the cognitive level, book clubs are used for interactive sharing and knowledge management. At the technical level, blockchain, big data, AI and other technologies are combined to reshape the processes and scenarios of the financial industry, starting from a local perspective. My relationship with blockchain stems from my own interest in blockchain, which I often study and discuss with some friends. Of course, some of the views are still relatively superficial. I hope everyone can share their opinions and make more comments and corrections.

Elite think tanks in the United States once believed that the core of maintaining global leadership is technology, technology must rely on the economy, and the core of the economy is finance. So, what is the future of finance?

Today’s topic is: The current situation and prospects of blockchain finance. I would like to introduce it mainly from three aspects:

A brief introduction to finance and the financial system;

The current situation of blockchain finance;

The outlook for blockchain finance .

1. Finance and financial system

1 The concept of finance

First of all, let’s talk about the concept of finance. The word “finance” originated from the Meiji Restoration (1868 Japan after 1897, this is somewhat related to the gold standard established by Japan in 1897. It was introduced to China from Japan in the early 20th century and was first proposed by Finance Minister Liang Qichao in 1902. At that time, Zhang Zhidong raised objections. Therefore, China has remained on the silver standard after the Sino-Japanese War of 1884-1899, but this also allowed China to avoid the 1929 decade of the Great Depression.

The original meaning of finance is "money financing", which refers to the circulation of funds in society. Later, its meaning was expanded to mean money., credit-related transactions and economic activities. There is actually another reason why it is translated as "finance": gold was once the only medium in international trade, and value and wealth were based on gold as the basis and standard. Therefore, when people make standard gold bars, they need to melt the gold into shape. This may be the original meaning of the word "finance", which is to melt the metal.

Finance is the general term for currency circulation and credit activities and the economic activities related to them

Let’s take a look at our later definition of finance: Finance is the currency circulation and credit activities and the economic activities related to them. A general term for the economic activities related to it. Finance in the broad sense refers to all economic activities related to the issuance, custody, exchange, settlement and financing of credit currency, even including the purchase and sale of gold and silver. Finance in the narrow sense refers specifically to the financing of credit currency.

To put it simply, the content of finance can be summarized as the issuance and withdrawal of currency, the absorption and payment of deposits, the issuance and recovery of loans, the purchase and sale of gold, silver and foreign exchange, the issuance and transfer of securities, Insurance, trust, domestic and international currency settlement, etc. To put it more bluntly, finance feeds back in both directions. The institutions engaged in financial activities mainly include banks, insurance, securities, trusts, financial leasing, etc. We all know this quite well and have frequent contact with it. Therefore, after understanding the meaning and institutions of finance, you also need to understand China’s financial system.

2 China’s financial system

The development stage of my country’s financial system can be roughly divided into five stages:

Initial formation stage, the first five years ( 1948-1953): The People's Bank of China was established (1948). The People's Bank of China at that time was far from what we imagine now. But it marked the beginning of the new Chinese financial institution system.

The "grand unification" system of central bank unified revenue and expenditure, the second five years (1953-1978): The People's Bank of China is the only financial institution in the country that handles various banking businesses, integrating the central bank Integrated with ordinary banks. In fact, the great unification is that we copy the foreign model. I will not talk about the specific countries.

Initial reforms and breakthroughs in the "unified" financial institution system, the third five years (1979 to August 1983): Bank of China (established in 1912), Agricultural Bank of China (established in 1951) , China Construction Bank (established in 1954) have been restored or established one after another, but the People's Bank of China still integrates currency issuance and credit. We have seen that China’s financial industry has developed very rapidly after reform and opening up.

The diversified financial institution system began to take shape. In ten years (September 1983 to 1993): it formed with the People's Bank of China as the core and four major majors in industry, agriculture, China and construction. A system of financial institutions with banks as the main body and various other financial institutions coexisting and cooperating with each other. After 1987, Bank of Communications, China Merchants Bank, Shenzhen Development Bank, CITIC and Hengfeng emerged one after another. In 1988, Ping An, Guangfa and Xingye emerged. In 1992, Everbright, Huaxia and Pudong Development Bank emerged and the China Securities Regulatory Commission was established in the same year.

Building and improving social ** market fundsThe stage of the financial institution system (1994 to present): A relatively complete financial institution system has been formed, led by "one bank and three committees", with large, medium and small commercial banks as the main body, and various non-bank financial institutions as auxiliary wings. In 1994, three major policy banks (China Development Bank, Export-Import Bank of China, and Agricultural Development Bank of China) were established. In 1995, Minsheng Bank, the first private commercial bank, was established (this is of great significance). In 1998, city commercial banks appeared. and established the China Insurance Regulatory Commission. The China Banking Regulatory Commission actually appeared relatively late, and was only established in 2003. From then on, the pattern of one bank and three conferences was formed. However, not long ago, the China Banking Regulatory Commission and the China Insurance Regulatory Commission merged to form the China Banking and Insurance Regulatory Commission. You can pay attention to it.

From an evolutionary perspective, normative research in finance is often linear.

That is, we often use a certain evolutionary form as the standard (usually a developed market economic system, such as the Soviet Union, Germany, the United States, and even Japan, etc.) to describe the financial system from non-marketization to marketization, from financial The path to progress from inefficient allocation of resources to efficient allocation, and focusing on explaining the GAP and reasons for this standard form.

In fact, we can find from the development history of China’s financial system just now: Since 1978, China’s financial system has evolved in the direction of marketization, standardization, diversification, and internationalization. Both scale and complexity are rising rapidly and non-linearly:

Various financial institutions have shown a "networked" and "strongly related" business format, that is: today's banks and banks, banks The correlation with other financial institutions and various financial sub-markets has increased significantly, and credit connections have become increasingly tight, intertwined, and intricate.

The ecological environment of the financial industry has also seen some significant changes. On the one hand, traditional formal financial institutions seek to accelerate transformation and innovation, and strive to seize opportunities in innovations such as business strategies, market positioning, management structures, business formats, and products. On the other hand, various emerging financial institutions have emerged in large numbers.

The financial industry also presents new characteristics such as real estate financialization, "banking" of non-bank institutions, and asset securitization.

The above changes are beyond the common imagination of the industry, regulators and policymakers, and will bring a series of impacts:

On the positive side, the scale and composition of the financial system have The business expansion and financial service capabilities of financial institutions have been expanded, the financial market has been developed, and innovative payments have developed rapidly. This is the case with financial technology, which we will talk about later.

To use a popular saying, there are all kinds of birds in the forest. Then, the negative aspects are mainly reflected in the following aspects:

The interactive relationship between the financial system and the real economy tends to be complicated, and the role of the financial system in spawning and amplifying asset bubbles has been underestimated.

The network and strong connections of the financial system have widened the gap between the financial industry and financial supervision, weakening the effectiveness of traditional supervision. my country's current financial regulatory system has only been in operation for more than ten years.

Monetary policy through goldThe transmission path and mechanism of the financial system have changed (the transmission chain of monetary policy has been lengthened or deformed, and the conductivity and effectiveness have declined), and the initiative and effectiveness of regulation are facing new constraints. The current monetary policy framework has been continuously improved in response to economic and financial market developments since its establishment in 1996. However, the complexity of the financial system in recent years has posed new challenges to it. Broad money M2 has also been impacted by factors such as financial deepening and electronic payments, and has been further weakened by the shadow banking system.

Various cross-market, cross-business, and cross-border behaviors that avoid supervision make multiple risk factors intertwined, such as: capital pool operations with serious mismatches in terms of terms and products hide greater liquidity risks, product Nesting leads to risk transmission, insufficient shadow banking supervision, local debt, real estate, external shocks, etc., all of which pose great challenges to the stability of the financial system.

There is no harm without comparison. my country's financial system as a whole is still relatively backward. This backwardness is mainly reflected in the lag in banking innovation: the People's Bank of China announced the cancellation of "interest spread protection" in October 2015, while the United States had completely marketized interest rates as early as April 1986, and China was nearly 30 years late.

3 The institutional framework and basic issues of China’s financial system

Of course, my country’s current financial system is based on three basic institutional frameworks:

The first is to rely on business trust existing in legal provisions, that is, policy guidance;

The second is to rely on a third party as a credit intermediary to ensure the realization of asset transfer transactions;

The third is to rely on centralized The clearing house is the center and handles the settlement and clearing of completed transactions.

Based on this, four issues have been raised:

1) The issue of integrity system and trust mechanism. Traditional finance must have strict transaction records to accumulate credit. Without transaction records, it is difficult to achieve financing or loans because there is no technical means to ensure the security of transactions between both parties.

2) Transaction settlement takes a long time. Traditional financial transaction times continue to speed up, but settlement times are still relatively long, especially cross-border transactions, which often cannot arrive immediately.

3) The cost of intermediary services is high. The important source of income of the traditional financial transaction system relies on collecting transaction fees or loan interest; in cross-border transactions, costs caused by exchange rate changes have to be paid.

4) Poor security. Traditional finance has many human involvement links, which means that the probability of human errors and omissions is also higher.

Faced with this series of problems, financial institutions have actually been looking for solutions. When we communicated with ICBC and China Merchants Bank two years ago, they were already exploring big data, artificial intelligence and blockchain. And its crisis awareness is very strong.

4 Financial Technology

As the positive aspects just mentioned, financial institutions have been seeking solutions to financial informatization and financial digitalization.

So, let me mention what is happening in financial technology. Whether it is FinTech proposed by JD.com or TechF proposed by Ant Financial,in, I think it is essentially a better combination of technology and finance, just like what we will discuss next is how to better combine finance and blockchain.

Financial Technology 1.0 Era

At this stage, the financial industry and the technology industry exist as parallel industries. The two sides have not yet truly integrated, but technological progress has begun to promote the globalization of the financial market. change. Since World War II, the rapid development of communication technology and information technology has enabled finance to break national boundaries, and the cross-border investment of financial institutions has also greatly accelerated. The main providers of financial services in this era were banks.

Financial Technology 2.0 Era

Technology is promoting finance and strengthening the trend of globalization, making financial services more and more digital. The financial industry realizes the electronicization and automation of offices and business through the application of traditional IT software and hardware, thereby improving business efficiency. During this period, financial institutions have significantly increased the adoption of IT technology in internal operations and have successfully implemented paperless offices in many processes. Core systems, credit systems, clearing systems, etc. that are often discussed in banks and other institutions are representatives of this stage.

Financial Technology 3.0 Era

In the Internet financial stage, the main force of financial technology at this stage is entrepreneurial enterprises of non-financial institutions, relying on Internet technology and information and communication technology to provide financial services or Cooperate with financial institutions to launch financial services. The financial industry builds online business platforms and uses the Internet or mobile terminal channels to bring together massive users and information to realize the interconnection and interoperability of any combination of the asset side, transaction side, payment side, and capital side in financial business. This is essentially a change from the traditional The transformation of financial channels enables information sharing and business integration.

Fintech 4.0 Era

The financial industry uses new IT technologies such as big data, cloud computing, artificial intelligence, and blockchain to change traditional financial information collection sources and risk pricing models. , investment decision-making process, and the role of credit intermediary, it can greatly improve the efficiency of traditional finance and solve the pain points of traditional finance. The representative technologies are big data credit investigation and intelligent investment advisory.

Having said this, let’s briefly summarize: Finance is the intermediary of credit, and finance provides two-way feedback. We talked about China's financial system and learned that ICBC, China Merchants Bank and Ping An were established at the same time, so we know why ICBC is more active and innovative than the other four major banks. Then we talked about the development of financial technology, which has led to better development of financial technology in information and digitalization.

Excerpts from: Article: Current Situation and Prospects of Blockchain Finance

6. What is blockchain technology and how does it change business and financial models

Blockchain technology is a distributed ledger technology that allows multiple participants to jointly maintain a secure, transparent and tamper-proof record on a decentralized network. Blockchain technology was originally designed for the digital currency Bitcoin, but is now widely usedMany other areas.

The core features of blockchain technology include:

Decentralization: Blockchain has no central control agency, and data is distributed on various nodes in the network, which makes it decentralized. The centralization feature reduces the risk of single points of failure.

Transparency: Transaction records on the blockchain are public to all participants, and anyone can view these records. This helps increase trust and reduce the risk of fraud.

Immutable: Once a transaction is recorded on the blockchain, it cannot be easily modified or deleted. This guarantees data integrity and security.

Smart contracts: Transactions on the blockchain can be automatically executed to implement "smart contracts", which automatically execute corresponding operations when specific conditions are met. This helps simplify complex business processes and reduce costs.

Blockchain technology has had a profound impact on business and financial models, which is mainly reflected in the following aspects:

Reducing costs: Blockchain technology can reduce intermediary links and reduce costs. Transaction costs and operating costs. For example, by adopting blockchain for cross-border payments, remittance fees can be significantly reduced.

Improve efficiency: The automation and smart contract features of blockchain technology help improve the efficiency of business processes, reduce manual intervention, and reduce error rates.

Enhance trust: The transparency and non-tamperability of blockchain technology help to establish a reliable trust system, reduce the risk of fraud, and provide better protection for business activities.

Innovative business models: Blockchain technology has spawned many new business models, such as decentralized finance (DeFi), digital asset trading, supply chain finance, etc. These new business models have brought disruptive changes to existing industries.

In short, blockchain technology, as an emerging technical means, is gradually changing the landscape of business and finance. With the continuous development of technology and the in-depth promotion of applications, blockchain is expected to have a more extensive and far-reaching impact in the future

7. Is blockchain useful? What impact and prospects does blockchain have?

I believe everyone is no longer unfamiliar with the emerging technology of blockchain, because it is the most popular topic at the moment, and many big guys in different industries are analyzing its role and prospects. Today we also do some analysis on the blockchain on whether the blockchain is useful and what the impact and prospects of the blockchain are. We hope it can help everyone.
Is blockchain useful?
1. Banking: As a digital, secure and interference-proof account, blockchain realizes the core function of the banking industry: a safe storage and transfer center of value. In other words, in the next few years, a wave of companies based on blockchain technology may affect the banking industry.
2. Payment and transfer: Blockchain technology can avoid complicated systems and create a more direct payment process between the payer and the payee. Whether it is a domestic transfer or a cross-border transfer, this method has its advantages. Low price and fast features, and there is no intermediate handling fee.
3. Network security: Although the blockchain system is public, its verification, sending and other data exchange processes use advanced encryption technology. This technology not only ensures the correct source of data, but also ensures that the data is not intercepted during the process. If blockchain technology is more widely used, the probability of being attacked by hackers may also decrease, so people think that blockchain systems are more stable than traditional systems. One of the reasons why blockchain systems can reduce traditional network security risks is that they eliminate the need for middlemen.
4. Election: Everyone's vote "can never be modified or deleted by us - programmers, school administrators or students."
5. Smart contract: Smart contracts are actually on another object. A computer program that functions on the go. Like ordinary computer programs, smart contracts are also an "if-then" function, but blockchain technology enables the automatic filling of these "contracts" without manual intervention. Such contracts may eventually replace the legal merger industry's core business of drafting and managing contracts in both commercial and civil areas.
6. Stock trading: For many years, companies have been trying to simplify the process of buying, selling and trading stocks. Emerging blockchain technology startups believe they can go beyond the past, automating the entire process, improving security and efficiency.
What impact and prospects does blockchain have?
1. The dual impact of bringing wealth and risk:
The difference between blockchain technology and traditional Internet technology is that it chooses the high-risk financial industry as the entry point, but the financial field is full of Areas with many obstacles. Such direct entry has a dual impact: on the one hand, it can bring wealth effects to entrepreneurs relatively quickly; on the other hand, various risks will also come directly and violently.
2. Improve efficiency and reduce costs:
For physical finance, blockchain can maintain the fidelity in the process of transmitting information, such as personal credit information and other data, thereby avoiding many transaction costs and enabling large-scale Improve efficiency, this is the positive meaning it brings.
3. Control financial risks early and small:
Blockchain is cooperating with the innovation of digital currency, preventing over-insurance in the insurance industry, over-lending in bank mutual funds loans, and the integration of supply chain finance. , promote electronic identity recognition, etc., applicable to many industries and fields. In terms of financial security, many companies have also cooperated with regulatory authorities to build regulatory technology systems to help regulatory authorities monitor and provide early warning for the risks of Internet financial companies, so as to control financial risks early and at an early stage.
4. The owner of the data should be the user himself:
Blockchain is a technology worthy of attention, and it has relevant layouts in its own business and investment. Bitcoin and other electronic currencies are applications based on blockchain technology. They have certain currency functions and have certain use value. However, the main problem now is that the gap between the use value and the transaction price is too big. . ICO is a financing business model.
5. The darkest stage contains the most opportunities:
The darkest stage often contains the most opportunities. The application of blockchain is far more than just currency and finance. For example, in the future, big data can be applied to the entire medical health. field. If medical records and diagnosis data are shared to all different medical systems through the big data blockchain, the efficiency of treating diseases and saving lives can be greatly improved.
The editor believes that the correct development prospect of blockchain is to "talk less about financial innovation, focus more on financial security, focus more on inclusive finance, and do more on medical care, health, and environmental protection."
The above is the blockchain brought to you by the editor. Is it useful? What impact and prospects does blockchain have? all content.

8. Application of blockchain in the financial field

1. Application and development of blockchain

Some Internet, Internet start-ups and traditional finance The industry has begun to try and apply blockchain in some projects

2. Domestic financial institutions are testing the waters of blockchain

Various financial institutions are testing the waters one after another, and they are basically in the conceptual experimental stage and have not yet Large-scale commercial use.

3. Panoramic view of blockchain application in the financial field

4. Ghostwriting

5. Digital bills

Bills are an important financial product in the financial market. They have dual functions of payment and financing. They are of high value and bear bank credit or commercial credit. Once a bill is issued, its face amount, date and other important information cannot be changed. Bills also have circulation attributes and can be accepted, endorsed, discounted, rediscounted, collected and other transactions within a specific life cycle. Once the transaction is completed, the transaction cannot be revoked. There are two characteristics in the circulation of bills: First, the circulation of bills mainly occurs through bank acceptance bills, and the number and circulation of commercial acceptance bills are small; second, each bank independently conducts credit granting and risk control on the bill business, and a single bank's Risk control results may affect other participants in the bill market transaction chain.

The experimental production system of the digital bill trading platform uses SDC (Smart Draft Chain) blockchain technology to protect privacy through cryptographic algorithms such as homomorphic encryption and zero-knowledge proof. The Byzantine Fault Tolerance Protocol (PBFT) performs consensus and uses a see-through mechanism to provide data monitoring.

The experimental production system includes four subsystems: the stock exchange, bank, enterprise and monitoring: the stock exchange subsystem is responsible for managing the blockchain and monitoring the digital bill business; the bank subsystem has the acceptance and receipt of digital bills, Business functions such as discount signing, rediscounting, collection and repayment; the enterprise subsystem has business functions such as digital bill issuance, acceptance, endorsement, discounting, prompt payment, etc.; the monitoring subsystem monitors the blockchain status and business occurrences in real time
