1. Is such an emerging technology as blockchain very practical?

A storm suddenly set off on the Internet - "blockchain", overwhelming "blockchain" "Blockchain" information is mixed with words such as "black technology", "revolution", and "get rich overnight". People are confused about this "blockchain". What exactly is this "blockchain"? Why is it so? Hot?

The explosive development of the blockchain industry in 2018, which is known as the "first year of blockchain", has caused enterprises and even BAT business giants to set foot on the blockchain and sit in one place. seats.

So what fields can blockchain technology be applied to in the future?

1. Financial field

Blockchain is the underlying technology of Bitcoin was extracted, so it is naturally applicable to the financial field. At present, the application of blockchain in the financial field is mainly explored in several aspects: digital currency, payment and clearing, digital bills, bank credit management, proof of equity and exchange securities transactions, insurance management and financial auditing, etc.

In May 2018, Tencent and the Shenzhen Municipal State Taxation Bureau jointly established the "Smart Tax" Innovation Laboratory, which uses cloud computing, artificial intelligence, blockchain, big data and other technologies to promote the "Smart Taxation" In-depth cooperation in the field of "Internet + Taxation". At present, "Smart Tax" will focus on exploring digital invoice solutions based on blockchain, with the goal of solving the problem of counterfeit invoices first.

2. E-commerce field

Today, my country's e-commerce industry is developing rapidly. While developing rapidly, it has exposed some hidden dangers of "counterfeiting" and it is difficult to distinguish the authenticity of goods. , but after applying blockchain technology, the authenticity of products can be traced in the supply chain. At present, both JD.com and Alibaba have entered the blockchain and want to use blockchain technology to combat "counterfeiting".

Blockchain e-commerce is also gradually emerging as a new e-commerce model. Using the characteristics of blockchain, it can trace the origin of goods and check their authenticity.

The Granary APP uses the characteristics of blockchain technology to trace the entire process of goods, and applies blockchain technology to users’ shopping, sharing, browsing and other scenarios. Among them, it is gifted to users through Token (tradable digital proof of rights), in which various participants can share and use data as needed to achieve high reliability of the data trading market, low-cost transactions and win-win for all parties.

Film and television field

Film and television is known as a "high-income" and "high-risk" industry. Regardless of whether a film and television project is successful or not, the initial investment is huge. There are many factors that affect the success of a film and television project: script, actors, production team, publicity, box office, etc. These problems can be effectively solved using blockchain technology.

With our familiar HLW ChainFor example, by allowing users to invest in project scripts on the HLW Chain, users can choose scripts and participate in the film and television production, promotion, and movie viewing process. To ensure the quality of the film, it can effectively and accurately predict the box office revenue after the film is released, and can also introduce investment funds. Blockchain technology has the characteristics of a distributed ledger, and everyone can participate in accounting, so

2. Has the JD Blockchain White Paper been released?

On March 22, JD.com officially Released a white paper on blockchain solutions, stating that it aims to use blockchain as a "linker" and combine its accumulated experience in new technologies such as cloud computing, big data, artificial intelligence, and the Internet of Things to build an integrated smart supply chain system. Retail network and financial technology bring the distance between products and customers closer. Under the guidance of the group strategy of Unbounded Retail, it fully opens its own blockchain technology accumulation.

JD Group Chief Technology Officer Zhang Chen said that in order to promote the development of blockchain technology and the integration of various business scenarios of JD Group, blockchain technology will be used to promote value big data. For the recording, flow and exchange of blockchain technology, JD Group has combined various internal functions, technologies, and business systems to carry out special research on blockchain technology and application development trends, and compiled the "JD Blockchain Technology Practice White Paper (2018)". The white paper summarizes the development status and direction of blockchain core technology in JD Group, shares typical application cases of various business implementation practices of JD Group, and puts forward relevant suggestions for the blockchain technology development roadmap and standardization roadmap.

3. What are the applications and successful examples of blockchain?

Blockchain can be applied to all walks of life. Taking e-commerce as an example, in order to solve the problem of fake goods in e-commerce In order to solve the pain points of logistics, integrity, supervision and other aspects, major enterprises and platforms are also showing their talents and using all their tricks. Blockchain is used as one of the more feasible means, so how does it solve these problems?

First, supervise the production process of goods. When visiting online stores, the biggest worry is buying fake products, especially overseas products. In addition, there is also the price problem caused by fake products. How to buy products at reasonable prices while ensuring the authenticity is really a headache. The transparency and irreversibility of blockchain technology allow consumers to check the production place, manufacturer, raw materials, etc. of goods at any time.

Second, trace and track the transportation of goods. A series of operational activities such as supply chain, inventory, and logistics involved in e-commerce will involve multiple intermediaries. The decentralized, non-tamperable, and traceable characteristics of blockchain make the entire process transparent, and any partner can You can check the inventory and payment status, which can effectively solve the "bullwhip effect" problem in the supply chain. (Bullwhip effect: refers to a phenomenon of demand variation amplification in the supply chain. The fundamental reason for its occurrence is the lack of communication and trust mechanisms between upstream and downstream enterprises in the supply chain. Demand information is transmitted upwards along the supply chain. Continuous misinterpretation.) At the same time, blockchain smart contractsCan be used to regulate intermediaries such as logistics and payment management partners. Simplify the huge management system to improve efficiency.

Third, guarantee product sales and after-sales service. At present, three-quarters of the transactions in China's e-commerce market are completed on the mobile terminal. Payment trust is a major problem that the platform needs to solve, and blockchain is known as a "trust machine." To give you an example, many websites Stores will fake orders or falsify data in order to get good reviews. Once the purchase information is uploaded to the chain, it cannot be tampered with to ensure authenticity. You can check the merchant's real transaction records to ensure whether the merchant is trustworthy.

Fourth, protect user privacy. The private key, public key, and encryption algorithm of the blockchain can solve this problem. Each user has his own independent address, and due to the anonymity of the blockchain, companies cannot publish or store user information and are protected from hackers. s attack.

For specific implementation, we take the two domestic e-commerce giants as examples. Alibaba has begun to introduce blockchain since 2016. First, Ant Financial launched blockchain technology to pay for charity donations, which was the first test of blockchain technology; in 2017, Ant Financial’s technology experiment The Office announced the opening of blockchain technology to support imported food safety and product authenticity traceability; in 2018, Cainiao and Tmall International announced the use of blockchain technology to track and verify the full logistics information of cross-border imported goods. These data include goods The country of origin, country of shipment, loading port, mode of transportation, import port, bonded warehouse inspection and quarantine order number, customs declaration number, etc.

Logistics and product traceability are indeed a good entry point for blockchain to enter the e-commerce field. As one of the domestic e-commerce giants, JD.com is certainly not to be outdone. In 2017, JD.com announced the establishment of " Jingdong Quality Traceability Anti-Counterfeiting Alliance", united government departments at all levels to build a Jingdong blockchain anti-counterfeiting traceability platform through the alliance chain; in December of the same year, it jointly announced the establishment of the China National Engineering Laboratory for E-commerce Transaction Technology with Walmart, IBM, and Tsinghua University The first safe food blockchain traceability alliance.

4. How to define blockchain and what are the application scenarios of blockchain?

Many people now think that blockchain is a universal technology that can do anything. Blockchain technology is a myth!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.

Definition of Blockchain: Narrow VS Broad

As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.

Blockchain technology features include:

Blockchain is a database storage system that is distributed around the world and can operate collaboratively. It is different from traditional database operations - read Write permission is in the hands of a company or a centralized authority (a characteristic of centralization). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).

At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.

At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.

As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.

Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.

The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything else. Some people said that this was the arrival of a new era, and the past has become classic, while others said To say that everything is hype is ultimately a bubble.

In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.

Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.

Taking online works rights protection as an example, byOnline rights protection generally adopts the method of collecting evidence after the fact, and does not conduct real-time confirmation of rights when the evidence is generated. Therefore, the entire rights confirmation process takes a long time, and the evidence collection is difficult and costly. It is extremely difficult to provide evidence and trace the source, and it is impossible to satisfy the needs of online works. Spread quickly and in large quantities.

eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated in the process in real time. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.

Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.

Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.

Through the following limited cases, I hope everyone can understand the actual performance of blockchain technology, thereby stimulating interest in such solutions.

1. Administrative Services

Over the centuries, the roles and responsibilities of public administration have not changed significantly – or rather, what has changed dramatically is actually the size of the data and the specific ways in which public agencies handle it. Although various digital technologies already exist to help collect and process data, issues such as anonymization, portability, and the immutability of large amounts of data remain unresolved.

Sasha Ivanov, founder, entrepreneur and CEO of Waves Platform and Vostok projects, said, "What the public administration currently lacks is a more convenient user experience (UX) for data use. To improve the user experience , we should introduce some kind of layer to it that acts as a trusted common environment that is transparent and can store data anonymously and immutably."

Governments around the world are gradually facing the existence of such problems by launching federal agency and enterprise-level programs such as the US Federal Blockchain Initiative. The United States held its first federal government blockchain forum in July 2017, and the U.S. General Services Administration currently has more than 200 related use case repositories. Ivanov explained, “Distributed systems can really help us build such a reliable environment, improve our big data work, and even integrate all emerging technologies – including artificial intelligence and the Internet of Things. In fact, , whenever we face any kind of technology, it always embodies the sum of certain other technologies."

Now, the system supported by the blockchain can actually work - this This view has been unanimously recognized by all experts and has become the most important theoretical basis. In other words, what we need to do next is create more production-ready solutions.

2. Payment services

The government needs to process transactions, many of which involve the exchange of funds with citizens. Blockchain technology has huge potential application value in reducing the cost of fund transfers - including using new blockchain-based cryptocurrencies as intermediate transaction carriers, or using blockchain as a means of fund transfer, etc. Once a perfect solution is discovered, the business opportunities will be endless - especially for those who need to conduct frequent cross-border or Internet transactions.

The Jasper project was developed by the Bank of Canada to help it further think about how central banks and other financial institutions should implement payment operations between different banks based on distributed ledgers. The Bank of Canada has also developed its own digital currency variant, “CAD Coin,” to test the feasibility of using a national currency on top of the blockchain.

This project brings to an interesting conclusion that we should say no to proof-of-work public chain systems. In a paper titled "Project Jasper: Is a Distributed Batch Payment System Feasible?" the author observed that "Proof-of-work systems are not suitable for such large transaction processing systems because they assume that all transactions in the system are There is a need for openness and observability to a certain extent.”

3. Digitization and intellectual property

Governments are responsible for maintaining copyright records and databases. These records prove ownership of intellectual property. A blockchain-based system would allow artists, performers and writers of all kinds to time-stamp their works and theoretically detect copyright infringements and even keep a permanent record of their rights. In fact, many governments have already taken important exploratory steps in this direction.

Iran recently announced that it will deploy this technology. "Iran Financial Tribune" quoted Morteza Mousavian as saying that "the digital media department of the Ministry of Culture has reached an agreement with a blockchain company to jointly design aA set of systems that can be used to protect online copyright. "He also added, "Relevant programs will soon be released to users in an easy-to-use manner. ”

This work is still in the early stages of exploration, but it provides corporate customers with the possibility of preserving records through replication technology. From a theoretical level, companies can use blockchain solutions for financial accounting, And discover the errors in real time.

4. Welfare distribution

The government has the responsibility to create a level playing field for citizens. Citizens who are chronically poor or economically disadvantaged certainly Government support and assistance is needed to ensure that they are able to maintain their lives and acquire the ability to continue to develop. However, welfare distribution is neither simple nor often straightforward. Problems such as corruption and imposters have been seriously undermining government programs. Various distribution channels.

In China, the National Council of Social Security Fund is conducting early research on how to use blockchain technology to improve the delivery of national benefits to citizens. At the same time, India is also taking action , Andhra Pradesh and Telangana are already using blockchain to support their civilian resource supply systems.

It is said that many companies, including Microsoft, are also considering using the same technology. These solutions, which will touch individual employees and functional roles, are expected to gradually appear in small businesses in the near future.

5. Tendering activities

In order to build public infrastructure or provide For related services, governments hope to achieve economies of scale and competitive gains through tendering as much as possible. However, the tendering process is often not fair or transparent. Public procurement has long been a major scene of rampant corruption around the world. Transparency International pointed out, “Many governments will award project contracts to one supplier in the absence of fair competition. This allows companies with greater political resources to unfairly outcompete competitors; or companies in the same industry negotiate bids in advance to ensure that each company gets a piece of the tender pie. This will significantly increase the cost of delivering services to the public – we have found that corruption issues can increase project costs by 50%. ”

So, how can blockchain technology solve the bidding problem? According to Ivanov, “Unlike decentralized centralized systems, independent ledgers powered by blockchain will be able to improve bidding or Transparency of any other financial processes that need to be tracked. The intervention of blockchain technology will help track the use of funds and ensure that they are paid out as expected and within the allowed time. ”

Currently, Japan’s Ministry of Interior and Communications has announced a blockchain-based bidding system, which means that in industries with serious collusion problems, small and medium-sized enterprises are expected to usher in a more transparent bidding method and Brighter development prospects.

Although mentioned beforeA considerable number of cases are far from finalized, but they do provide many possibilities for enterprises and governments. Of course, the key lies in implementation; and we should also look at all this with optimism, that is, although blockchain technology is often misunderstood, it is and will eventually find a direction in which it can exert its own energy!

< p> In layman's terms, the blockchain is like a dozen beacon towers on the Great Wall. If an enemy comes at one place, they will send out smoke. The other beacon towers will know about it and enter a defensive state together. In technical language, it is a distributed ledger. Each node keeps accounts separately. The failure of one or two nodes will not affect the entire network.

How is this distributed network different from the distributed servers of Google Network? Google Network's distributed servers still belong to Google Network and are controlled by their central scheduling algorithm. The distributed nodes in the blockchain do not know each other and have no legal relationship. You can just go offline and shut down if you want, but because of the currency rewards, there will always be someone who will turn on the machine as a new node to support the network.

After the popular and technical explanation, I hope you understand. So the first application scenario is finance. I put my money in Alipay. If Alipay doesn't recognize it one day, there's nothing you can do. But on the blockchain, it is useless if one node does not acknowledge it, because other nodes still have my records. The second is the contract. Nowadays, contracts are made on paper and are easy to be faked. But if they are put on the blockchain, they cannot be faked.

There are more application scenarios. It is recommended to check the top 100 digital Huobi online to understand the corresponding projects behind them and become a blockchain expert. .

Blockchain technology was first used in Bitcoin. Blockchain provides a reliable and trustworthy means of organizing data for cross-subject business scenarios. JD.com is essentially a supply chain company, and blockchain technology will be first used in many scenarios of the supply chain.

Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.

The most popular application industry at present is the financial industry.

An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since traffic fraud in digital advertising causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud

In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a basicA new ecological model based on technological trust

The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.

Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.

In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.

At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.

What is blockchain

If you use non-technical terms to explain blockchain, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone, so In the Internet, a place where data and information are exploding, having such a place would be like a magical treasure.

What can the blockchain do?

If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:

Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.

If there are any deficiencies, you are welcome to comment and correct me.

In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.

The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.

Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire trading network has changed from a star structure to a point-to-point P2P structure.

In the future, blockchain will be used in many fields and will have a great impact on human life. It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.

1. Cloud storage

This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?

Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.

2. Medical aspects

Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.

5. Why SF Express and JD Logistics are accelerating the application of blockchain technology

In the field of logistics, blockchain technology can play a role in traceability and reconciliation , credit reporting and other functions. It is understood that SF Express uses blockchain in logistics services to compress intermediate links in logistics services and improve the overall efficiency of the industry on the premise of optimizing resource utilization. JD Logistics is also accelerating the deployment of blockchain technology to realize that each product has its own unique blockchain "ID card". At the same time, it also built a blockchain document platform, a blockchain reconciliation platform, and a trusted warehouse receipt service platform, combined with the Internet of Things, AI, and GIS technologies to ultimately realize the digitization of logistics documents, the contractualization of operating rules, and the assetization of logistics data. .
Blockchain has significant advantages such as decentralization, distributed accounting, and encrypted traceability, which can well ensure the integrity and authenticity of on-chain data. Once it has been tampered with or forged, it can be discovered. At the same time, because the blockchain has the characteristics of distributed accounting, even if the data on individual nodes is deleted, other nodes can still completely save the data, ensuring the integrity of the entire blockchain certification system. normal operation. Based on the above advantages, blockchain is naturally suitable for electronic data storage. The introduction of blockchain certificate storage can effectively solve the authenticity and legality issues of electronic evidence, making the electronic data certificate storage process more trustworthy. Future industry trends will develop based on the "blockchain+" model. Yibaoquan uses blockchain technology to effectively solve the whole-link trust issue of electronic data from generation, storage, notarization, and proof: when uploading to the chain, the blockchain is used to ensure the originality and integrity of the storage data. After being uploaded to the chain, each judicial node on the security chain is used to ensure the credibility and security of the data.nature; during litigation, evidence can be sent directly to the Internet court to improve the efficiency of rights protection.

6. What fields do these blockchain application companies mainly focus on?

There are many application scenarios for blockchain. The little secretary below will tell you about several fields that are currently widely used:

(1) Blockchain + electronic invoice

In August this year, Shenzhen The National Taxation Bureau and Tencent will jointly form a laboratory management committee and jointly release the first blockchain invoice in the country, marking that the era of blockchain invoices has arrived.

(2) Blockchain + product traceability

On Tmall’s Double 11 today, Tmall once again boasted a turnover of 213.5 billion yuan. Ant blockchain product traceability was applied to 150 million products such as diamonds, imported milk powder, beauty cosmetics, health products, Wuchang rice, and Moutai during Double Eleven, which once again demonstrated the charm of the new technology blockchain to consumers. In addition to Tmall, JD.com’s cold chain also traces the origin of JD.com’s fresh food. Many e-commerce platforms have also begun to apply blockchain in the field of product traceability. Vaccine incident

(3) Blockchain + content
The first public chain - Ulord, users can build decentralized applications through this platform and conduct digital media without third-party intervention For content sharing, Ushare, the world's first decentralized experience value sharing platform based on the Ulord public chain, has begun public testing. Ushare gives non-head users the opportunity to advance through the ranks, eliminating the need for content middlemen. Through the pricing contract mechanism, tokens are distributed to everyone who forwards, likes, and reads, changing some of the current unreasonable interest patterns, making the entire mechanism more scientific, and the same content is distributed more widely.
(4) Blockchain + Finance

Technology giant IBM officially launched a blockchain-based cross-border payment solution at the end of August 2018 - IBM Blockchain World Wire. European banking groups, including HSBC, announced in July this year the completion of the first real-time blockchain-based cross-border financial transaction. In June 2018, Ant Financial announced that the world's "first" blockchain-based e-wallet cross-border remittance service was launched in Hong Kong, and the first remittance was completed on-site.
(5) Blockchain + Insurance

The mutual insurance that has suddenly become popular in the past two days is the innovative result of the combination of insurance and blockchain. After eliminating the high threshold of traditional commercial insurance, Mutual Insurance adopts a zero-yuan insurance purchase method to maintain fairness with the rule that one person's illness is shared by many people. Users can buy as they want and withdraw as they want. The platform only charges some management fees, which makes the district The concept of open and transparent distribution after decentralization of the blockchain is fully developed and exquisite. High transparency is achieved through blockchain technology, ensuring that there will be no insurance fraud or default.
(6) Blockchain + Intelligent Manufacturing

Alibaba, JD.com, IBM and other well-known domestic and foreign companies have begun to get involved in the blockchain + intelligent manufacturing business. IBM cooperated with Blue Ocean Camel to build a blockchain + foreign trade supply chain intelligent platform, Alibaba Cloud launched its own enterprise-level blockchain service BaaS (Blockchain as a Service), JD.com’s blockchain service platform Zhizhen Chain, etc.

(7) Blockchain + Medical

The main advantages of blockchain technology are decentralization, non-tamperability of information, and information transmission and sharing based on consensus mechanism. In all aspects, we can achieve the purpose of ensuring information security in various scenarios.

Overviewing the current development of blockchain technology and the characteristics of the medical field, we believe that the application of blockchain in the medical field can be mainly divided into the following four aspects: institutional medical information security and privacy protection; Personal medical information security and privacy protection, medical insurance and supply chain management.

7. In the 3.0 era of blockchain, how to play the blockchain app

If Bitcoin represents the blockchain version 1.0, it proves to the world that digital currency can accomplish. Then Ethereum represents the 2.0 version of the blockchain, letting everyone know more about how to play the blockchain, decentralized applications and smart contracts. In 2018, blockchain will enter the 3.0 stage. Applications and scenarios will be the core of blockchain. Applications based on blockchain will spring up in various industries. This will be the last stage of blockchain development. early bonus period. The demand for talents driven by the application of blockchain technology has been increasing. Blockchain technology talents have become an upstart profession, highly competitive, and also have enviable high salaries.

More and more large companies are entering the blockchain industry, and Dufeng Huanlv strives to become the "leader" in this emerging field. Among them, Alibaba, SF Express, JD.com, etc. have all hired technical talents in the blockchain field with high salaries. In this information age with the Internet as the core, the competition among large companies is ultimately the competition for talents. Especially when the emerging blockchain technology is first emerging, blockchain technology talents are “in hot demand” whether at home or abroad. As a "young" technology, the main force for future development is bound to be young people. However, many current practitioners in the blockchain industry are self-taught and have no systematic professional knowledge training, or are just cryptography, programming, and the Internet. Technical and other unilateral talents. Blockchain technology values ​​​​more complex talents with multiple technologies. In the future, with the maturity of the application of blockchain technology, talented people will become more popular to "recharge" themselves and devote themselves to the blockchain. Be prepared for the heat. In addition to participating in blockchain development work, what else can help you catch up with the blockchain train? Investing in blockchain projects is obviously another approach. So how to judge whether a project is a real blockchain or a fake blockchain?

Is the cost of confirming the authenticity of information in this field very high? For example, there is a Christian coin project, which usesThe blockchain records the time people spend reading the Bible, and then issues Christian coins to these people. Let’s not discuss whether it is meaningful to count the time people read the Bible. Even if it is meaningful, this can be solved completely with other models. For example, when checking in in a WeChat QQ group, why should we develop a blockchain smart contract and imitate the blockchain? I'm afraid I'm just cutting leeks to keep warm. So what are the areas where it is difficult to confirm the authenticity of information? The most typical one is finance. There is a large amount of information asymmetry in financial markets, which makes the market full of uncertainty. For example, when transferring money, you won't know until the bank tells you that it has arrived. Now blockchain technology can solve such problems better and faster. Similar information confirmation issues such as market data, credit, contracts, etc.

Whether a meaningful large-scale consensus is formed: One of the outstanding advantages of the blockchain is that it can effectively form a large-scale consensus through public ledger accounting and notification to the entire network. Nowadays, for many projects, there is no need to form a network-wide consensus. Some are just for crowdfunding and issuing tokens. The blockchain consensus of the project is meaningless. Does this model have a network effect? ​​The network effect means that a project will become more valuable as the number of project users increases, because the value of the project does not lie in the users themselves, but in the connection network between users. Bitcoin is a classic example. The more user nodes there are, the links between nodes will grow exponentially, and the entire Bitcoin ecosystem will be more valuable.

Of course, in addition to these points, there are many basic principles for judging projects, such as effective incentive mechanisms, strong teams, project solutions to pain points, etc.

8. What are the applications of blockchain

1. Blockchain + product traceability
This year’s Tmall Double 11. Ant Blockchain used blockchain for the first time to trace the origin of 160 million commodities.
JD.com and 7FRESH use blockchain to ensure the quality of hydroponic vegetables.
Carrefour’s blockchain product Guanxi Honey Pomelo is launched.
2. Blockchain + Electronic Invoice
The Shenzhen Taxation Bureau of the State Administration of Taxation has opened up the WeChat payment platform and launched the "WeChat payment blockchain electronic invoice" function. In October this year, WeChat Pay electronic blockchain invoices were used on a trial basis at some merchants in Shenzhen. The official launch this time means that all merchants in Shenzhen who have opened WeChat Pay can log in to their own WeChat Pay merchant platform to directly activate the blockchain electronic invoice function.
3. Blockchain + Law
The judicial blockchain of the Internet Court is online, and the electronic evidence stored on the chain has legal effect. The Hangzhou court used blockchain to adopt key evidence, which was used by a technology company in Shenzhen on its website. The technology company then became the defendant.
4. Blockchain + Content

The first exemplary vertical content social DAPP based on the Ulord public chain. It is the world's first decentralized experience value based on the ulord public chain. A sharing platform that allows users to create, share, and disseminate experience value while receiving corresponding awards.Incentives, stimulate value re-creation, and form a virtuous cycle of content ecology.
5. Blockchain + Insurance
Ant Financial announced the first mutual aid case of the online mutual aid program "Huang Bao". A 5-year-old girl from Shanghai received a serious illness mutual aid fund of 300,000 yuan. For all For participants, each person shared an average of 0.03 yuan. In addition to case details, in order to ensure information openness and transparency, the public notice also issued medical diagnosis certificates, discharge summaries, surgical records and other information, and stored the data on the blockchain.
6. Blockchain + Health
The health energy chain based on the Ulord public chain is currently in internal testing.
7. Blockchain + Intelligent Manufacturing
Blockchain + Intelligent Manufacturing Well-known domestic and foreign companies such as Alibaba, JD.com, and IBM have begun to get involved in the blockchain + intelligent manufacturing business. IBM cooperated with Blue Ocean Camel to build a blockchain + foreign trade supply chain intelligent platform, Alibaba Cloud launched its own enterprise-level blockchain service BaaS (Blockchain as a Service), JD.com’s blockchain service platform Zhizhen Chain, etc.

9. What convenience can the blockchain service platform launched by JD.com bring to the operation of enterprises?

The concept of blockchain has become very popular in recent years, but in addition to digital currency ( Except for use in the field of virtual currency), there have not been many implementation projects in other fields. JD.com’s recently released “Zhi Zhen Chain” can be said to be an important attempt to implement blockchain in business scenarios. After all, JD.com itself is already very large and has established a relatively complete ecosystem. If “Zhi Zhen Chain” If it can gradually be implemented and play a role within the JD system, it will have a lot of reference value for blockchain applications in the commercial field.

The blockchain itself has the characteristics of tamper-proof, traceability, full process, decentralization, etc., and these characteristics are more consistent with the e-commerce field where market operation is relatively clear. In my opinion, the blockchain platform created by JD.com can bring the following benefits:

First, products can be traced. Product anti-counterfeiting has always been a headache for e-commerce platforms, and it also accounts for a large part of the e-commerce platform's expenses. After using blockchain technology, product tracking can be completed to ensure product traceability. Product authenticity will no longer be a problem that troubles merchants.

Second, the service is traceable. Not only products can be traced, but services can also be traced using blockchain technology. Services that follow products are often one of the core factors that affect user experience. Making services traceable can build a service system to facilitate smoother connection and cooperation between merchants and between merchants and users.

Third, standardize bill (contract) management. Invoice management has always been a troublesome matter in a business environment. After using blockchain, standardized management of invoices can be completed. Blockchain notes have natural characteristics such as being unforgeable, tamperable, traceable, and verifiable, and these characteristics can avoid a large number of transaction risks.

Fourth, the process is intelligent and standardized. By using “Zhi Zhen Chain”,Many companies participating in the JD platform can effectively use the "Smart Chain" to complete various business operations (to be developed and improved), which greatly lowers the entry threshold for participating companies.

I believe that the "Smart Chain" will be further developed and improved in the future, and will also bring more convenience and benefits to service merchants.

My research direction is big data and artificial intelligence. I am currently leading graduate students in related fields. I will continue to write some popular science articles on big data on Toutiao. Friends who are interested can check it out. If you pay attention to me, I believe you will gain something from the demolition tribe.

If you have any questions about big data, you can also consult me.
