A. Blockchain applications include

Blockchain applications include:

(1) Blockchain + Medical: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health records (EHR), DNA wallets, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.

(2) Blockchain + Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the IoT of blockchain technology Networked applications will become a very important application field.

(3) Blockchain + IP Copyright & Culture and Entertainment: The Internet is developing better and better, and digital music, digital books, digital videos, digital games, etc. have gradually become mainstream . The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry.

Blockchain has the characteristics of disintermediation, consensus mechanism, and non-tampering. Using blockchain technology, it can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time , can realize the value transfer of digital content, ensure the credibility, auditability and transparency of the transfer process, and effectively prevent piracy and other behaviors.

(4) Blockchain + Public Services & Education: In the fields of public services, education, charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. Traditional The method is to rely on a credible third party for credit endorsement, but problems such as fraud and deficiencies still exist. Blockchain technology can ensure the integrity, permanence and unchangeability of all data, and thus can effectively solve the difficulties and pain points in these industries in terms of certificate storage, tracking, association, and backtracking.

B. 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. The supply chain involved in e-commerce,A series of operational activities such as inventory and logistics will involve multiple intermediaries, and the decentralized, non-tamperable, and traceable features of the blockchain make the entire process transparent, and any partner can view the inventory and payment status. It can well 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. Keep misinterpreting.) At the same time, blockchain’s smart contracts can 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.

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

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

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 global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are 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.

Blockchain is a distributed ledger (database) that connects data blocks in an orderly manner and cryptographically ensures that it cannot be tampered with or forged. technology. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. Blockchain as an underlying protocolProposals or technical solutions can effectively solve the trust problem and realize the free transfer of value. They have broad prospects in the fields of digital currency, financial asset transaction settlement, digital government affairs, and certificate deposit and anti-counterfeiting data services.

Digital currency

After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the characteristics of easy portability and storage, low circulation cost, convenient use, easy anti-counterfeiting and management, breaking geographical restrictions, and better integration.

Bitcoin technically implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also released a white paper on its cryptocurrency Libra. Whether it is Bitcoin or Libra, the underlying technology they rely on is blockchain technology.

my country began the development of central bank digital currency as early as 2014. my country's digital currency DC/EP adopts a two-tier operating system: the central bank does not directly issue digital currency to the public. Instead, the central bank redeems the digital currency to various commercial banks or other legal operating institutions, and then these institutions exchange it for public supply. its use. In early August 2019, the central bank held a video conference on work for the second half of the year. The meeting called for accelerating the pace of research and development of the national legal digital currency.

Financial asset transaction settlement

Blockchain technology naturally has financial attributes, and it is causing disruptive changes in the financial industry. In terms of payment and settlement, under the blockchain distributed ledger system, multiple market participants jointly maintain and synchronize a "general ledger" in real time. Payment, clearing, and settlement that currently take two or three days can be completed in just a few minutes. tasks, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track transactions on the chain and quickly locate high-risk capital flows. In terms of securities issuance transactions, traditional stock issuance has long procedures, high costs, and complex links. Blockchain technology can weaken the role of underwriting institutions and help all parties establish fast and accurate information exchange and sharing channels. Issuers handle issuance on their own through smart contracts, and regulatory authorities With unified review and verification, investors can also bypass intermediaries and conduct direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.

Digital Government Affairs

Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to be centralized on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "instant reimbursement after invoicing" - in seconds Level invoicing and minute-level reimbursement accounting greatly reduce tax collection and management costs, and effectively solve problems such as data tampering, over-reporting of one ticket, and tax evasion. Poverty alleviation is another practical application of blockchain technology. Utilize the characteristics of openness, transparency, traceability, and non-tampering of blockchain technology to achieve transparent use, precise investment, and efficient management of poverty alleviation funds.

Evidence-based anti-counterfeiting

Blockchain can prove the existence of a file or digital content at a specific time through hash timestamps, and it is open, non-tamperable, and traceable. It provides perfect solutions for judicial forensics, identity certification, property rights protection, anti-counterfeiting and traceability, etc. In the field of intellectual property, the digital signature of blockchain technology and on-chain certificates can confirm the rights of text, pictures, audio and video, etc., and create and execute transactions through smart contracts, allowing creators to regain pricing power and preserve data formation in real time. The evidence chain covers the three major scenarios of rights confirmation, transaction and rights protection. In the field of anti-counterfeiting and traceability, blockchain technology can be widely used in various fields such as food and medicine, agricultural products, alcohol, and luxury goods through supply chain tracking.

Data services

Blockchain technology will greatly optimize existing big data applications and play a huge role in data circulation and sharing. In the future, the Internet, artificial intelligence, and the Internet of Things will generate massive amounts of data. The existing centralized data storage (computing model) will face huge challenges. Edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the non-tampering and traceability mechanism of blockchain ensures the authenticity and high quality of data, which becomes the basis for all data applications such as big data, deep learning, and artificial intelligence. Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation. In response to the current blockchain development stage, in order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will effectively reduce enterprise blockchain deployment costs and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.

The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything. Some people said that this is the arrival of a new era, and the past has become classics. Others said that everything is hype. After all, It's 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.

Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.

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.

From a technical perspective, blockchain is not a brand-new technology, but a distributed data storage, point-to-point transmission,New application models of computer technologies such as consensus mechanisms, encryption algorithms, and smart contracts. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.

Due to its advantages such as "decentralization", "distributed data storage", "traceability", "anti-tampering", and "openness and transparency", blockchain technology can effectively solve data problems. By establishing a trustworthy data management environment, we can prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote the efficient sharing and application of data. In the process of practice and exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions, and continues to empower public resource transaction management services.

Facilitate transaction data sharing and transaction witnessing

Facilitate transaction data Share

Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. It is difficult to verify the off-site performance provided by the bidders during the bid evaluation process. It is difficult to troubleshoot the same person repeatedly serving as project manager. Issues such as low cost of breach of trust. Establishing a cross-regional subject database based on blockchain can well alleviate the above problems.

The distributed ledger feature based on the blockchain can effectively ensure the real-time or quasi-real-time sharing of data, and can reduce the repeated entry of subject information; the use of blockchain information that cannot be tampered with can ensure the data circulation process on the chain. The authenticity of the bidders in the regional alliance is directly obtained from the on-chain data, making it impossible to hide the fake performance. At the same time, the sharing of bidding behavior data through the blockchain provides a data basis for the development of "joint punishment of dishonest enterprises".

Blockchain-based transaction witness

"Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" ( The State Office Letter [2019] No. 41) pointed out the need to optimize services such as witnessing, venues, information, files, and expert extraction. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing intensity, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witness system is prone to data tampering, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.

Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to solidify and store the data generated in each transaction link, and accurately record the data generated through time stamp technology, summary algorithm, and electronic signature technology. Time, content, data source. According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain, and for large unstructured format files, videos, audios, etc.The file saves its summary information through the blockchain, and the original file is saved through the distributed file storage service. When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction. Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.

Promote the rationalization of electronic guarantee rates

Promote financial services and corporate financing for bidding companies

Promote the rationalization of electronic guarantee rates

At present, electronic bidding deposit guarantee letters have certain applications in the field of bidding, solving the problem of bidding deposit funds for bidding companies. Occupancy issues. However, because financial institutions currently do not have reliable historical bidding behavior data of bidders, they are unable to judge the default risks of different bidders. As a result, the guarantee services charged to bidders adopt fixed rates, which makes a small number of bids with high default risks The cost of personal guarantee is allocated to most bidders with low default risk, which increases the guarantee rates for most bidders to a certain extent.

At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main choice basis for the bidder. If the bidder performance records are shared through the blockchain and the performance risks of different bidders are analyzed, it will be Different bidders provide different guarantee rates, which not only reduces the risks of financial institutions, but also reduces the use costs of most bidders and promotes the use of bid guarantees. To a certain extent, it can also encourage bidders to abide by their promises and maintain the order of the bidding market. .

Promote financial services for bidding companies

The bidding behavior of bidders is scattered in various trading centers, and the data is simply aggregated In a centralized information system, there is a risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be gathered and shared safely and reliably. Through blockchain technology, bidders from multiple trading centers are gathered, and historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate the bidders' credit in the bidding sub-sector.

Solving the financing problems of successful bidders

Traditional corporate loans mainly evaluate the company's solvency: collateral, audit There are requirements for accurate financial statements and sustained profitability, but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become problems faced by many small and medium-sized enterprises in bidding activities. Using the methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools. With the help of the non-tamperable characteristics of blockchain, it gathers first-hand business data from multiple trading centers and combines it with big data analysis technology to buildCredible bidder portraits. On the one hand, it improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.

Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. Centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data trustworthiness but also reduces the risk of corruption. The entire system relies on a centralized authority.

Through further analysis, we found that credit sales are currently prevalent among domestic enterprises, and the upstream suppliers of the winning bidder have a large funding gap. The credit of the bidder can only be passed to the winning bidder (the winning contract cannot be split or transferred), and the upstream suppliers Business owners are unable to obtain high-quality loans from financial institutions. If the winning contract is converted into a "pass" on the chain, the "pass" can be split, and the winning bidder holding the "pass" can pay part or all of the voucher to the upstream supplier, making it discountable and financing. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduce bidders' costs.

Regarding blockchain, we can imagine a decentralized management model and technical processing method.

Let me give you an example. There are five people in your family, and they have never been able to figure out how to arrange work and handle family relationships.

So, you and your family discuss it together and simply use voting to solve the problem.

Then this way of voting to solve problems can be called the most elementary blockchain.

Decentralization solves problems.

What application scenarios can blockchain have?

In fact, many of our families and many organizations use blockchain management forms every day

However, this kind of blockchain application for organizational relationships cannot produce Economic Value.

What are the economic applications of blockchain?

The first type is used for tax deposit certificates, bank transfers, etc.

Make full use of the traceability function of the blockchain so that all records can be retrieved and queried at any time

The second type is applied to enterprise operation and management

Enterprises using blockchain management can better solve the problems of enterprise development and enable enterprises to develop faster. , make more money.

Summary: The application scenarios of blockchain include taxation, bank transfers, etc., and can also be applied to business operations.

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.

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 new ecosystem based on technological trust. Mode

What is blockchain

If you explain blockchain in non-technical terms, 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. Therefore, in the Internet, a place where data and information are exploding, having such a place will be like a magical treasure land.

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 anTherefore, 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 transaction 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.

D. What role can blockchain technology play in the field of environmental protection?

Now many public welfare organizations have begun to use blockchain technology. After the epidemic, In this era, the three pillars of the digital economy are the outbreak of the new online economy, the steady development of intelligent manufacturing, and the rise of the contactless economy. New infrastructure has become a hot topic of discussion during the two sessions and a growth point in the future, and blockchain is empoweringIt has unique advantages in ecological and environmental protection.

Construct a digital points reward mechanism: The establishment of residents’ environmental awareness is not directly proportional to their actual actions. For example, the importance of environmental protection is generally recognized. In “garbage classification”, it is difficult to classify , difficult processes, difficult management and other "difficulties", with little effect. The use of blockchain technology can establish a points reward system so that everyone involved in environmental protection can create visible "value" and stimulate people's enthusiasm. The point-to-point transmission method of the blockchain not only ensures the security of points, but also avoids corruption and other problems and the consumption of human resources caused by the traditional "top-down" method;

Environmental protection Traceability of the entire management process: In terms of garbage classification and recycling of old items, we have made many years of efforts before, but it has not achieved good results. The reason is that the garbage is classified but the garbage truck is still loaded in one place or the garbage is transported to the treatment plant and is still burned together. , making garbage classification and recycling meaningless. In the blockchain, the information of every item in the garbage classification is fully transparent and traceable, ensuring that our environmental protection work is implemented effectively.

"Innovation Workstation" is the only approved "blockchain technology professional" pilot workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

E. How to use blockchain technology to promote the integration of green finance and industry? What is its prospect and significance

A core function of blockchain is cross-validation and risk control. It can reduce financial risks and improve financial efficiency.
The integration of industry and finance is mainly to promote the return of finance to the real service economy. Blockchain can help funders find better projects, so that good industries will develop better with financial support.
Data on corporate accounts receivable can often directly reflect the company's production and sales scale, corporate efficiency, financial status and other information, and are closely related to the development and survival of the company. In recent years, accounts receivable in various industries across the country have remained high, which has seriously affected the capital turnover of enterprises, making it impossible for enterprises in the debt chain to operate normally, struggle, and even go bankrupt. Therefore, the management of accounts receivable has become a very important issue in business activities. How to monitor the occurrence of accounts receivable and how to deal with the company's bad debts?

F. How to apply blockchain technology and what role it can play

Take buying a house as an example: Buying a house is a complex transaction process, and the participants include sellers, buyers, and intermediary companies. , housing authority, bank, appraisal company, tax bureau, etc. Throughout the transaction process, all participants must record their own ledgers separately. Checking these ledgers is a very time-consuming and laborious task, and the verification cost is very high. That's why the entire process of buying a home now takes an average of two months.

In addition to being time-consuming and labor-intensive, since there is very little information that can be verified by a single participant, there is a risk of being "cheated at both ends" by the intermediary company, or "sold for more than one house". However, blockchain provides a solution: integrating all participants' ledgers into a trustworthy and non-tamperable digital ledger, which can be queried by all participants. In this way, every aspect of the home buying process is clearly visible, and everyone can conduct transactions with less time and effort.

Bitcoin is the first application of blockchain technology. Without the operation and management of any centralized organization, Bitcoin has maintained stable operation for many years without any problems. Through this case, everyone saw the potential of blockchain technology.

In order to prevent single points of failure and systemic risks, the current financial industry requires strict supervision and layer-by-layer audits to control risks, which also results in high internal costs. The traditional cross-border settlement method is through intermediaries like SWIFT, so the settlement speed is very slow. However, Bitcoin has been running perfectly for many years without the operation of a centralized institution. It can not only realize settlement and clearing in real time, but also There was not a single accounting error.

According to a report released by Santander, Spain’s largest bank, if all banks around the world use blockchain technology internally around 2020, they will save approximately US$20 billion in costs per year. Such data is enough to illustrate the tremendous changes and breakthroughs that "blockchain" has brought to the traditional financial field.

H. How is DB Kerong Securities doing now? Can I get back the money I invested?

DB Kerong Securities has a capital operation model similar to China Securities Capital CCG. If you Before investing, I would definitely advise you to be cautious (that is, do not invest). But now that you have invested, you can hardly get back the money you invested, and there is nothing you can do about calling the police. I can only give you an analysis on how to avoid being cheated in the future.

How does this capital operation model attract people to invest?

First step, company packaging

The English name of China Securities Capital Group is Capital Clearance Group. It comes from the United States and has branches in many countries (using overseas companies as its umbrella to increase domestic investors It is difficult to investigate the company. First of all, there is no way to check the company's qualifications on the Internet.)

Foreign executives from a well-known university.

The second step, professional and uncommon financial terms

"Credit asset securitization", "cash asset securitization", and "security auction" are not long-term exposure to financial investment project terms , the key point is that no matter what is a gold investment product, there are risks! ! ! No matter what product you invest in, there are risks in investing. Remember that high risks are high and returns are high.

The third step, use "capital operation" to cover up the facts of pyramid schemes

A very classic case of financial investment, please refer to the Internet "Pompei Trap", the originator of pyramid schemes.

The entire fraud model of China Securities Capital has been exposed by Southern Weekend.

Now analyze DB Kerong Securities through Q&A on the DB Kerong WeChat public account.

How to make money from DB Neutron Coin?

There are two ways to make money

①Pure static dividends

That is, without any promotion, after investing, the company will give you 3.5 times to 5 times Times leverage is added to your account, and you can enjoy one thousandth of the company's dividend every day. The security price will increase by US$0.03 every two weeks. The bonus securities are converted into neutron coins (neutron coins are also constantly appreciating) and then transferred to the trading market to be sold directly. Withdraw cash.

②Dynamic Bonuses

Upgrade your agent and do the market and you can get dividends every day. The company will give you a 10% direct promotion bonus based on the amount of investment you make in promoting members, 9-12% matching bonus.

Analysis: The first way, as an electronic currency, where is the trading market? Appreciation also has a price but no market. On the one hand, if this project operates normally and can directly obtain Neutron Coin dividends, why bother buying it in the circulation market? On the other hand, if the project cannot operate normally, no one will buy the Neutron Coin, and it will not be circulated.

The second method is a simple and straightforward MLM model. Isn’t the word “agent” obvious enough? All industries! I mean everything, the market is limited, "agents" must be a few people to make profits, everyone acting as "agents" is a pyramid scheme.

2. What is the investment allocation of this security?

The investment allocation is 62% electronic currency and blockchain, 10% p2p online lending, 8% payment platform, 5% biometric technology, and 15% other combinations.

Analysis: Please pay attention to 62% of electronic currencies and blockchain, please watch the ""Focus Interview" 20170214 Secret web link for Bitcoin network fraud and money laundering" web link

3. Investment What is the profit point of this security?

The first is stable, daily returns, providing regular income to investors through corporate profits; the second is high returns, the appreciation of securities achieves high returns on capital through the strong growth of financial technology companies, and the third is low Risk, owning assets collateralized by fintech companies.

Analysis: If you really want to invest and manage money, please always remember that 2 and 3 are completely contradictory! Risk and reward must be inversely proportional.

Finally, please work hard and don’t lose confidence in life just because you were cheated once. I wish you a happy life.

I. What are the application fields of blockchain technology?

Application fields: financial field, Internet of Things and logistics field, public service field, digital copyright field, insurance field, and public welfare field.

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. This field is considered a promising application direction of blockchain.

Blockchain is closely related to people’s production and life in the fields of public management, energy, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain.

J. How Blockchain is Applied to the Food Chain

Summary

Chefs can make sure their food is sustainably sourced and organic through blockchain technology. How to make sure of that? IBM thinks the solution lies in Blockchain. IBM is connecting all players in the global supply chain from farmers, procers, suppliers, manufactures in a secure shared platform---blockchain.

Blockchain is a decentralized ledger where activities throughout the whole food supply chain are recorded, verified, and become immutable at each step. This technology applies to any numbers of vegetables from fresh to packaged.

It has three advantages:

Consumers can scan the code on the package to check where the food comes from and whether it is genuinely fresh etc.

It can remove the distributor in the middle.

Traceablity (one of the functions of blockchain) can help spot the problematic food instead of decimating the whole farm in case of a food-born outbreak

Blockchain is a decentralized distributed ledger. All transaction data on the entire chain can be recorded and authenticated in the ledger and turned into tamper-proof evidence. The application of blockchain in the field of food supply has three major advantages:

1. Because every step of food from farm to table is recorded on the ledger, the information is traceable. Consumers can obtain the source information of food by scanning the code.

2. Because every step of the transaction and information is open and transparent, trust in the supply chain is increased, and the middle agent between the farmer and the purchaser can be eliminated.

3. Because the information is traceable, if a certain food causes mass poisoning/disease spread, the problem food can be accurately found and the accidental killing of other healthy foods can be reduced.
