A. Forbes announced the top 50 blockchain companies, with Du Xiaoman Financial on the list

Recently, Forbes announced the list of the top 50 global blockchain companies, with Ant Financial and Du Xiaoman on the list. Five Chinese companies including Finance, Tencent, China Construction Bank and Foxconn are on the list. In addition, Amazon, Google, Microsoft, Samsung, IBM, etc. were also selected for the list.

The companies on the list own the basic technologies of cryptocurrencies such as Bitcoin and apply them to accelerate business processes and improve In transparency, billions of dollars in cost savings can be realized. At the same time, the list also requires the companies on the list to have annual revenue of no less than US$1 billion, or a valuation of more than US$1 billion. For the companies on the list, blockchain technology has been truly reflected in revenue and cost savings.

Du Xiaoman Financial has explored and implemented multiple blockchain projects, one of which allows millions of ordinary Chinese users to adopt and trade cute digital puppy pets "Leitz Dogs" - these pets All are different and “live” on the blockchain. It also has a service that provides education loans, "Anxinfu", which uses blockchain technology to ensure that students consume teaching services before allocating funds. Du Xiaoman uses a variety of blockchain implementation solutions, including Hyperledger Fabric developed by IBM.

Currently, the application of blockchain technology has extended to many fields such as digital finance, Internet of Things, intelligent manufacturing, supply chain management, and digital asset transactions. At the same time, major countries around the world are accelerating the development of blockchain technology.

In October 2019, the country emphasized that blockchain should be used as an important breakthrough for independent innovation of core technologies, and clearly proposed to accelerate the development of blockchain technology and industrial innovation, and actively promote blockchain and economic and social integrated development. Some people in the industry believe that this is a new positioning of the blockchain at the top level and has been elevated to a national strategy.

Among the large domestic Internet companies, Duxiaoman Financial is at the forefront in accumulating and implementing blockchain technology.

In addition to the projects on the list, Duxiaoman Finance is also actively innovating in the fields of distributed finance. The distributed finance white paper released in 2019 was the first in the industry to propose reference technologies for distributed finance. architecture. In the field of consumer finance, Duxiaoman Finance, as a pioneer, launched the blockchain ABS (asset securitization) project to solve the problem of trust in the authenticity of the underlying assets of all parties to the transaction.

In 2017, Du Xiaoman Financial jointly issued the first domestic ABS project supported by blockchain technology with partners such as Baiqian Leasing and Huaneng Trust. The issuance scale was 424 million yuan. This was the first domestic ABS project. It uses blockchain technology as the underlying technical support to realize the project of ABS "real assets"; in the same year, it also released the "Network-Chang'an Xinsheng-Tianfeng 2017 First Phase Asset Support Special Plan", which means China's first blockchain-based project The implementation of exchange asset securitization products based on blockchain technology has alsoIt is the product with the lowest interest rate issued in the current period.

The above-mentioned project was recognized by the academic community for two consecutive years in 2018 and 2019, and was selected into the case library of Peking University Guanghua School of Management, becoming the school’s first classroom teaching case based on blockchain technology; Won the 2019 "Excellence in Practice Award" from Harvard Business Review.

"Youqianhua" is a credit service brand under Duxiaoman Financial (formerly Internet Finance). It is a big brand, reliable, low interest rate and trustworthy. It provides personal consumer credit services to the public and creates innovative The consumer credit model inherits the technological genes of the Internet, and Youqianhua uses artificial intelligence and big data risk control technology to provide users with convenient, fast and secure Internet credit services.

B. What are the main application areas of blockchain technology?

Answer: The main application areas of blockchain technology include the financial field, the Internet of Things and logistics, public services, and digital copyright. fields, insurance fields and public welfare fields.

1. Financial field

Blockchain has potential huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges.

2. Internet of Things and Logistics Fields

Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved.

3. Public service fields

Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralized nature of these fields also brings Some problems can be solved using blockchain.

4. Digital copyright field

Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. sex.

5. Insurance field

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs.

6. Public welfare fields

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

C. What emerging industries are there now?

Emerging industries often represent a new direction of economic development. Making full use of it may inject new vitality into economic development and change people's lifestyles. What I feel most deeply is the convenience brought by black life in the Internet era. So what emerging industries are there now? Some of them may still be in their infancy. Let’s summarize them below.

1. In the blockchain industry, maybe everyone is still very unfamiliar with blockchain, and the official explanation is ambiguous. I am hereIt can be explained appropriately, for example, A and B bet, the betting capital is 10 yuan, but neither party particularly trusts each other, they find a middleman, but each charges 10 yuan as the middleman, but the middleman may also take the 20 yuan and run away to prevent this. , the blockchain was born. A program was compiled and put on the Internet for everyone to supervise and complete the bet. If someone A or B defaults, the entire Internet will know about it, and their credit will be reduced in the future. It's difficult.

What are the benefits of this blockchain, decentralization, cost saving, and improvement of personal credit. Maybe this industry is just in its early stages. We usually have central credit in all walks of life, the largest is the central bank, and Taobao, where we usually buy things. Maybe this is an ideal stage at the moment, but all countries are working hard to study and want to be in a leading position in this industry. For example, Bitcoin is related to blockchain.

I think these three industries are emerging industries with large development space and wide influence. They may also be extending into emerging subdivided industries in other industries, but The influence is not widespread. If you have other opinions, you can comment and communicate in the comment area. If you think it is well written, please give it a like and follow it for more stock information.

D. South Korea’s Samsung plans to launch a 5G mobile phone compatible with the RADR blockchain

The radar system is a fusion of blockchain and cross-border payment, compared with the traditional financial system The main advantages are:

First, under the blockchain point-to-point mode, it no longer relies on traditional intermediaries to provide credit certification and accounting services. Any financial institution can use its own network access system to achieve Point-to-point information transmission between payers and payors;

Second, all nodes in the blockchain share account books, point-to-point transactions between nodes are confirmed through the consensus mechanism, and the results are broadcast to all nodes, no longer Both parties to the transaction need to establish a hierarchical account agency relationship to achieve point-to-point value transmission;

Third, the distributed system architecture of the blockchain network does not have a central node. Each node on the network must follow the necessary protocols. Transactions and accounting are carried out spontaneously on a basic basis to ensure stability, reliability and business continuity;

Fourth, the timestamp in the blockchain ensures that all transaction activities can be tracked and queried , to achieve traceability of cross-border transactions;

Fifth, the handling of business in the blockchain requires the review of customer identities in accordance with KYC rules, and the conditions for value transmission are limited through blockchain smart contracts. Improve the automation of transactions.

After adopting the blockchain, we no longer rely on a central system (such as SWIFT) to be responsible for fund settlement and transaction information storage, but can directly transfer value based on a consensus mechanism. This consensus mechanism does not require Conduct any trust coordination.

The result of the mechanism transformation is that, on the one hand, it not only saves the huge server costs and maintenance costs of third-party organizations,It can also streamline business processes and reduce business costs for banks and customers; on the other hand, the flattening of processes increases the speed of cross-border transfers and enables real-time transfers, and because each node of the system stores a complete set of data copies , even if multiple nodes are attacked, the overall system can still ensure security!

E. Samsung applied for a patent for the name of the Blockchain series, which may be used in blockchain mobile phones

Samsung applied for a patent for the name including "BlockchainKeyStore", "Blockchainkeybox", and "BlockchainCore". It may be prepared for use in blockchain mobile phone related applications.

Just after Israeli startup SirinLabs announced the launch of the blockchain mobile phone Finney, and HTC also launched its first blockchain mobile phone EXODUS1, Samsung also seems to be planning to launch its blockchain mobile phone-related products .

Samsung had earlier submitted an application for patents with names including "BlockchainKeyStore", "Blockchainkeybox", and "BlockchainCore". At the same time, the patent content also pointed to the product category of smart phones and included applications. Description of software applications, computing software platforms, applications, etc. on mobile devices.

Judging from the narrative content, Samsung’s patents with such names are more likely to be used for blockchain-related services and may not be a mobile phone product. However, judging from the current development of blockchain mobile phones, it seems that Samsung does not rule out incorporating its own KNOX technology into the application of blockchain technology.

However, there is currently not much information about the details of Samsung’s registered name patent application, and Samsung has also stated that it will not respond to any rumors.

Prior to this, Samsung had invested in blockchain startups through its data systems company SamsungSDS earlier this year, and even announced that it would use blockchain technology to optimize global business. , allowing smart delivery of goods worth tens of billions of dollars each year to be more effectively controlled, and it is also expected to reduce pre-freight costs by about 20%.

In addition, Samsung has also stated that the security design of its smartphones is sufficient to ensure the security of digital currency transactions. Therefore, it does not seem surprising that its mobile phone products will be integrated with blockchain technology in the future.

F. Which brand of smart bracelet is better

Which brand of smart bracelet is better? In fact, the functions of various smart bracelet brands are almost the same, it mainly depends on your use. Exercise pedometer, sleep monitoring, heart rate detection, call reminder, etc. are the functions of most smart bracelet brands currently on the market. You can choose which smart bracelet is better according to yourself, and try to choose some well-known smart bracelet brands. There are many other functional bracelets, such as heart rate monitoring, sleep quality, etc.
I then started with existing wrist products, let’s discuss the functions of smart bracelets one by one.
1. Step counting
Currently, this is the basic configuration of the bracelet, and it is 100% standard.
Can a bracelet that cannot count steps still be called a bracelet? Maybe it should be called salted fish without dreams.
Smart bracelet products are based on the concept of health, and this function is the core function. The 3-axis g-sensor is made by ordinary manufacturers. The one with a magnetometer is a little more sophisticated and can filter out some interference factors, such as simply shaking off your hands and typing on the keyboard while driving. At present, no one uses gyroscopes with relatively high power consumption, and they run out of power in less than three days.
2. Sleep monitoring
This function seems to be liked by many people, but unfortunately not many are doing it well now.
Theoretically, wrist activity can be detected with an accuracy of 90%. It is a pity that this is rarely studied in China. A few products can accurately detect falling asleep and waking up. There are doubts about the accuracy of deep sleep. of. The current monitoring method of some manufacturers is to use piezoelectric films spread on the bed, which is more accurate than smart bracelets, but the results are still questionable, and there has not been a large number of tests to prove its accuracy.
3. Reminder
Among the domestic customer base, 90% of customers are extremely concerned about this function. This is the demand point for most domestic users to purchase wearable products.
4. Voice call
A portable Bluetooth sports bracelet headset.
Voice calls have never been very popular. 7 or 8 years ago, many manufacturers seemed to have made early wearable products such as watches and mobile phones, but they have never been very popular.
5. Decoration
Used as watches and decorations, this is actually quite important. Which brand of smart bracelet has a better decorative effect? ​​This is a matter of personal taste.
6. GPS positioning
This function is almost a necessity for parents with children and young people with elderly people at home.
The GPS route function is a point of interest for some running enthusiasts.
7. Sports guidance
This market is currently a niche market, and professional analysis of sports is not yet mainstream. From the perspective of technological development, smart bracelet products must achieve a certain level of professional sports guidance. With the development of technology, this will gradually become a basic function in about 1 or 2 years.
8. Health applications such as heart rate and blood oxygen
Heart rate bracelets are already relatively common, but bracelets with blood oxygen function still need to be further optimized.
Summary: Which brand of smart bracelet is good, objectively depends on the function; which brand of smart bracelet is good, mainly depends on the user experience.

G. What is blockchain and how to make money with blockchain

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 thisWith these characteristics, blockchain technology has laid a solid foundation of "trust", created a reliable "cooperation" mechanism, and has broad application prospects.
The ways to make money in the blockchain are as follows:
1. Coin speculation. Coin speculation is like stock speculation. Coin speculation is the lowest threshold for making money in the blockchain;
2. Vendors, district Blockchain is a global market. Like small traders, you can move from a low-price platform to a high-price platform to sell and earn the difference;
3. Earn commissions for promotion. The blockchain method is to register first Exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you can get a commission;
4. Mining, "mining" in Bitcoin is The accounting process;
5. Technical support, providing blockchain technical support to some teams and enterprises;
6. Opening a trading website and charging handling fees;
7. Developing wallets and wallets It is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain;
8. Be a blockchain project or infrastructure equipment supplier.

Warm reminder: The above explanation is for reference only and does not make any suggestions. There are risks in entering the market, so investment needs to be cautious. Before making any investment, you should ensure that you fully understand the investment nature of the product and the risks involved. After understanding and carefully evaluating the product, you can make your own judgment on whether to participate in the transaction.

H. Stable cryptocurrencies are rising, Online shopping will also transform accordingly

The third decade of the 21st century is about to begin. Cryptocurrency has begun to become the new main payment method around the world, and the various advantages of this emerging currency It is also becoming more and more known to people.

The impact of the COVID-19 epidemic is particularly severe. Fortunately, order is gradually being restored around the world; although a large-scale secondary outbreak is not impossible, considering the economic recession in many fields At this critical moment, governments around the world have to make trade-offs. Against this background, the discussion about the cash society model has intensified, with critics claiming that this old model can no longer cope with the new situation under the crisis. In other words, the coronavirus pandemic has actually accelerated the global transition to digital cash and cryptocurrencies.

The era of relying solely on legal tender is gone, and the role of cash as a financial tool has gradually been eliminated by history. For now, although the foundation of emerging digital e-commerce is still not solid enough, emerging cryptocurrencies represented by stablecoins are indeed expected to play a major role in the world.A new definition of assets is established within the scope.

Mobile services are impacting the global business market

Over the past five years, the popularity of mobile technology has largely promoted the overall evolution of the Internet, and the e-commerce industry has also taken advantage of this trend. The east wind of history is advancing rapidly. Demand for online shopping services continues to grow around the world, and the industry itself is developing rapidly. While multinational giants such as Google, Samsung and Apple continue to simplify the payment experience on smartphones, mobile commerce is beginning to grow faster than all other e-commerce categories combined.

Since 2015, the proportion of mobile applications in the e-commerce field has been steadily increasing. Data released by Statista shows that "by 2020, the total mobile retail revenue in the United States is expected to reach US$339.03 billion."

The emergence of many shopping applications has redefined the shopping methods that people have long been accustomed to, and most of them Most sales are closely related to mobile devices. People are beginning to realize that placing orders through apps is much more convenient than spending time wandering around in physical stores.

The technological savior has arrived, and merchants are seizing the opportunity

Blockchain technology may not represent the ultimate solution, but it does have the potential and potential to help the e-commerce field usher in a new wave of development. Practical use cases.

Recently, Amazon, one of the world's largest e-commerce brands, applied for a patent for its new DLT-based system, which is specifically designed to track every item in its supply chain.

Blockchain technology has powerful capabilities to quantify trust and establish unprecedented business relationships based on this principle, ultimately substantially improving the performance of enterprise service platforms. DLT-based tracking solutions fundamentally enhance the visibility of the entire supply chain from production to final status, helping users gain a clearer understanding of the goods they intend to purchase. In addition, this model will also bring tangible benefits to various participants such as manufacturers, express delivery companies, distributors, and end users.

When it comes to e-commerce, the widespread popularity of cryptocurrencies over the past few years has impacted not only the way people shop, but also the specific financial instruments they choose. With the rapid lowering of barriers to use, cryptocurrency-specific ATM machines are widely deployed around the world, and related trading institutions are also emerging. I believe it is only a matter of time before cryptocurrency will be recognized by the mainstream.

Stablecoins are rising rapidly

Network technology has only changed the overall shopping habits of the people, while DLT technology has truly brought what they urgently need to the acquiring, remittance and corporate settlement departments. Performance upgrade plan. For a long time, the existence of more and more intermediaries has brought a heavy burden to the existing financial system, and the result is that the processing efficiency has been declining. Faced with this reality, will distributed ledger technology and smart contracts one day be able to completely replace traditionalFinancial system? The answer is absolutely yes, it will just take some time.

First of all, we need to admit that we do not yet have a perfect payment method, and cash and credit cards are still the main means of payment for users to purchase products and services. In this regard, cryptocurrencies are expected to bring about a complete revolution and become the new form of payment in the remaining decades of the twentieth century. For us, the most important task at the moment is to evaluate which cryptocurrency is best suited to serve as a digital asset in an e-commerce scenario. Faced with more than 5,000 existing cryptocurrencies, Bitcoin and Ethereum undoubtedly have the most obvious advantages, which also makes them the most important value carriers in the early stages of development. However, because the trading prices of such assets are so volatile, it's difficult to consider them a reliable measure of value.

In order to take advantage of the decentralized technology of digital currency while also transcending the inherent flaws of legal tender and the shortcomings of the current financial system, stablecoins came into being. At present, some stablecoins are based on the same currency as the US dollar or The euro is directly pegged to alleviate the problem of excessive price volatility in traditional cryptocurrency transactions. Over time, most of these projects failed miserably because the selection of underlying assets was a complex and difficult task. But the good news is that in the face of the continued spread of COVID-19 and the volatile global financial situation, some stablecoin projects launched by private companies are still operating well and in good condition.

Introducing cryptocurrencies in businesses will bring many advantages. For example, fiat currencies have a more flexible calculation mechanism for transaction and refund commissions, which can help companies save money. In addition, these accounts are completely independent of centralized institutions such as traditional banks and can help merchants better manage their own funds.

Unlike the credit card payments we are familiar with, stablecoins are not restricted by geographical factors or traditional bank accounts. In other words, buyers and sellers can trade cryptocurrencies at any time, anywhere in the world.

In the foreseeable future, stablecoins are even expected to gradually transform from national currencies into internationally accepted currencies. This means that the financial connections between different countries will no longer be solely controlled by the central bank, but will truly be transformed into a powerful force that the people can control at will.

Buy with ease

In our era, you don’t need to master advanced programming skills to experience the benefits of cryptocurrency. During 2020, many companies introduced more secure and streamlined cryptocurrency gateways, while offering the option to purchase digital assets directly using credit cards. Nowadays, it only takes a few minutes to subscribe to the cryptocurrency of your choice using US dollars or euros.

In just a few years, cryptocurrency supported by blockchain technology has received widespread attention and support around the world - more and more institutions recognize the value of Bitcoin, and the purchase process of cryptocurrency has become more and more complex. The United States issued a digital dollar white paper, and China also launched a pilot project for the digitization of the RMB. There is no doubt that thisThe continuous advancement of technology will bring about new ways of life faster than we can imagine. Stablecoins are here, and new power is here.
