1. The trust mechanism of the public chain in the blockchain is

The trust mechanism of the public Kaiqing chain in the blockchain is proof of work. The workload proof shows the work ability and is more worthy of others' trust. Trust in the public chain is a new form of human trust collaboration, and it has the broadest scope of trust. As Professor Kevin Werbach of the University of Pennsylvania stated in his monograph on blockchain trust, providing the most general trust (credit) services to all users is the core value of the public chain, which has enabled mankind to achieve global success for the first time. Spontaneous trust. The basis of blockchain trust lies in the independent accounting and verification process of all parties in an equal and decentralized network. Each participant independently records and verifies each transaction and contract on the public ledger of the public chain, which has no threshold, free access, is held by multiple parties, and maintained by multiple parties. Under the consensus mechanism, every network participant may become an accountant (bookkeeper), and under the transaction confirmation and verification mechanism, every network (full node) is an auditor. Therefore, the public blockchain is a global accounting and auditing network.

2. Among the top ten international blockchain patents, two vice-president units of the Zhejiang Provincial Blockchain Technology Application Association occupy two seats

Among the top ten international blockchain patents, Zhejiang Provincial District The vice president unit of the Blockchain Technology Application Association occupies two seats! Among them, Ant Chain ranks first and 33 Complex Beauty ranks sixth!

After two years, what is the development trend of global blockchain patents? Faced with the entry of traditional Internet giants, can Chinese companies still maintain their leading position in patented technology?

On March 12, 2021, IAM once again released the latest research report on global blockchain patents. It is a matter of pride that Chinese companies once again lead the world in blockchain patent performance.

(IAM official social media picture)

According to Derwent data, the top ten Chinese companies have submitted a total of 3,066 "patent families", accounting for approximately the global total. nearly one-third. Ant Group maintains its first position with 2,298 patent families, Ping An Group has become the world's second largest blockchain patent applicant after experiencing a surge in numbers last year, Tencent ranks third, and Complex Beauty ranks sixth in the world.

It is worth noting that among the top ten Derwent patent families, nine are Chinese companies. There are technology giants such as Ant, Tencent, and Internet, large state-owned enterprises such as China Unicom and State Grid, as well as emerging technology companies such as Beijing Ruize Technology and Hangzhou Complex Beauty, which reflect the research and development and patents of blockchain technology by Chinese companies. Enthusiasm for investment.

First, patent applications are easy to file, especially if there are subsidies and other incentives, but only a smallSome can be eventually authorized; secondly, most Chinese companies on the list have a score of about 1 on average application breadth, which is an indicator of how many jurisdictions a patent family covers. The more countries a patent is applied for, the more rights it has. The greater the scope of legal protection and international potential.

4. BlueFocus and the Blockchain Data Foundation cooperate to explore marketing blockchain applications

Recently, the Blockchain DATA Foundation and BlueFocus reached an agreement Strategic cooperation, the two parties will work together to build the marketing blockchain laboratory of BlueFocus Kunlun Hall Research Institute. The two parties will cooperate on the technical implementation of the DATA project in data anti-fraud in the field of digital marketing, and will also jointly explore the broad application prospects of blockchain technology in the field of advertising and marketing.

BlueFocus was founded in 1996 and listed on the GEM in 2010. In addition to having branches in major domestic regions, BlueFocus also has an international business network in North America, Europe and other countries and regions in the Asia-Pacific. Asia's largest marketing communications company. In the context of the era of big data and social media, BlueFocus continues to increase data genes and technology genes through business innovation and investment and mergers and acquisitions, and achieves the integration of content, creative services and product technology capabilities, forming new core competitiveness. 2017, blueColorFocus has achieved a total revenue of 15.2 billion yuan, of which data technology business revenue accounts for nearly 90%. More than 20% of the ideas have been completed by independently developed intelligent service robots, and the intelligent management service platform has taken shape.

The DATA project is a decentralized terminal data credit protocol based on blockchain and driven by AI technology and P2P mobile storage architecture. The DATA project is committed to using blockchain technology to solve serious problems in the global digital ecosystem such as data fraud, low cooperation efficiency caused by lack of trust, waste of ecological resources, and uneven value distribution. Through terminal-level data trustworthiness assessment, the DATA project hopes to solve the problems of data traceability, confirmation of incentives, and quality control.

In March of this year, BlueFocus and Lakala Group jointly established the Kunlun Hall Big Data Research Institute, which consists of four major laboratories: cloud computing, artificial intelligence algorithms, service robots, and blockchain applications. And set up a research center in Silicon Zen Valley. BlueFocus hopes to integrate various forces to build a smart operation platform. In the future, it will rely on big data construction capabilities to realize the output transformation and in-depth application of scientific research results, provide a powerful engine for the intelligent development of the entire marketing system, and ultimately empower customers with smart operations. Ability to achieve business model innovation.

The two parties will carry out the following cooperation on the implementation of the DATA project and the exploration of blockchain technology in the field of digital marketing:

On the one hand, based on the accumulation of marketing communication services over more than 20 years , BlueFocus has a deep understanding and strong demand for digital marketing effect monitoring. BlueFocus will try to use the Data Authentication Protocol and other related technologies provided by the DATA project within the system to build the underlying blockchain infrastructure for terminal data quality monitoring and traffic fraud prevention. For example, its mobile intelligent marketing integration service company Domob focuses on mobile brand advertising, performance advertising and APP distribution, and has a one-stop programmatic advertising platform. By combining DATA, Domob can not only further improve its traffic anti-fraud system, optimize service processes and improve marketing efficiency, but also become a DATA ecological certification node and work with ecological partners to jointly govern the ecosystem.

On the other hand, the two parties will combine the actual needs of BlueFocus and its subsidiaries in the marketing field to explore more application scenarios of blockchain technology, and will be jointly organized by the Blockchain Data Foundation (Blockchain DATA Foundation) leads the research of the institute’s blockchain laboratory in the field of marketing. Through core mechanisms such as blockchain-based consensus engines and smart contracts, the two parties will conduct research on marketing alliance chain research and development, intelligent marketing, settlement and payment, and data privacy security. By combining AI and big datatechnology to jointly improve digital marketing efficiency and create more value for customers and ecological partners.

In this cooperation, BlueFocus will also join the Global Data Trust Alliance as a strategic partner to jointly build a true, mutually trusting and efficient global data ecosystem. The Global Data Trust Alliance is an alliance initiated by the Blockchain DATA Foundation with the goal of establishing a true and mutually trusting data ecosystem. Currently, the American marketing data monitoring and analysis company Kochava, XCHNG Global Zone Blockchain digital marketing platform and global mobile monetization optimization platform Yomob are both members of the alliance. At the same time, Kunlun Hall Marketing Blockchain Laboratory will also work together with members of the Global Data Trust Alliance to explore potential vertical application scenarios that blockchain technology can really empower in solving data trust.

5. Is ambc legal?

Fake. It is not safe to invest in AMBC. After checking through social finance, the African AMBC International Industrial Group showed that it was unable to return the query in China.

It is reported that with the blockchain craze, the most serious chaos has appeared in digital currency. These projects combine blockchain concepts and financial knowledge.

First of all, PS technology was used to package the MLM leader as the cover character of various magazines. (If you are careful, look at the connection between the pictures, you will see that there is no dent in the sofa when you sit on it). After this false start, the gimmick of blockchain digital currency was introduced.

(5) Zhengya Group Blockchain Extended Reading:

ambc is the "African Mining Industry" "State Investment Fund"

The actual controller of "Africa Mining State Investment Fund" is Sun Peng, who was born in Tai'an City, Shandong Province. Sun Peng was originally the person in charge of Tai'an Jincheng Taishan Jasper Industry Co., Ltd. and a member of the Second Tai'an CPPCC Committee. But Sun Peng had already started organizing and planning MLM activities ten years ago.

The judgment published by the Intermediate People’s Court of Jinan City, Shandong Province shows that on May 26, 2011, Sun Peng established Taishan Jasper Company to engage in the research, development, design and sales of Taishan Jade.

6. Can blockchain change 10 cases of existing business

This article introduces the current 10 main usage scenarios of blockchain:

(1) Tracking the world Products in the supply chain;

is a typical usage scenario of blockchain technology in security traceability. It can promote information tracking, query, verification and anti-counterfeiting of commodity circulation, and can significantly improve the efficiency of some links. However, the role of the blockchain can only be reflected in the chain, but it cannot cover the parts operated by people below the chain.

(2) Ensure 3D printing quality and tracking;

(3) Create personalized and lifelong “one-stop” medical records;

Blockchain healthcare can track anyone’s complete medical history, such as medications, illnesses, injuries, and transactions across health systems, doctors, pharmacies, and health plans, and empower patients to control their own data. Blockchain can also transfer insurance payments: smart contracts can automatically trigger insurance provisions when a clinic confirms a patient has received treatment, and prevent fraudulent or inaccurate claims. Some startups, such as the UK's Medicalchain, blockchain company Gem, MIT and other companies and universities are experimenting with this use.

(4) Simplify trade logistics;

Traditional trade involves complex import and export procedures, and all participants in the entire chain require a large number of paper documents to interact, resulting in high communication costs. Blockchain can optimize this system. Maersk and IBM have created a platform that integrates services such as liner, warehouse, freight forwarding, ports, customs, exporters, importers and trade finance banks into the trade ecosystem, on a data exchange platform running on the blockchain interoperate.

(5) Facilitate and secure customs trade;

Blockchain has been tested in many customs departments, including the United Kingdom, South Korea, Singapore, Costa Rica, Mexico, Peru and the 15-nation East African Group. In 2017, U.S. Customs developed 14 use cases for blockchain, which are currently being tested and evaluated. Blockchain will be particularly useful for the UK: when the UK leaves the EU customs union, its number of customs declarations will increase from 55 million to over 250 million (non-EU trade plus EU trade, which previously did not require customs documents), which is currently the case with UK software The program cannot fully handle it. Blockchain can help: It can trace the origins of products and help determine the origin and appropriate tariffs for goods, such as those destined to join the European Union’s tariff package. For the UK’s 28 border agencies, imported products such as food, safety and intellectual property compliance need to be analyzed, and blockchain projects can be shared securely and transparently in real time.

(6) Prevent voting fraud and protect voter identities;

Blockchain security and identity protection features can reduce fraud and encourage voters to believe their votes are anonymous,

increase turnout and make elections more immediate . Using the technology, voters can scan their thumbs with their smartphones and cast their ballots during their Election Day commute. If everyone votes via the blockchain, no one can vote twice. Voting records are inviolable, and the ID of each ballot is recorded instantly at every polling location.

(7) Launch crop insurance for farmers;

Crop insurance customized to specific farmer needs is often very expensive, and blockchain technology can reduce costs by determining trigger conditions and automating execution. For example, farmers can insure against extreme weather. If extreme weather affects a harvest, a blockchain-based insurance contract would immediately recognize this and pay the farmer’s claim.

Establishing a network of energy producers and users;

Decades ago, some companies introduced smart grids to provide intermediary services for energy producers and demanders. Now, blockchain can optimize smart grids and empower energy producersProvide a regional intermediary energy trading platform for consumers. TenneT and Brooklyn-based startup LO3 Energy are both trying this business.

(9) Create smart cities that can operate independently;

Blockchain can now amplify the impact of Douyou IoT on city operations. For example, Dubai has a pilot project to implement blockchain in city services. Dubai plans to use blockchain for more than 100 million annual government documents by 2020, including all visa applications, bill payments and license renewals.

(10) Automatic payment to the exporter when the goods arrive at the foreign buyer;

Blockchain changes the information asymmetry in existing international trade by allowing both parties to the transaction to access the same data and real-time digital files question. There is no need to store multiple copies of the same document across different databases for different entities. When goods arrive marked by sensors connected to the smart contract, a transfer of money from the buyer to the seller is automatically triggered.

2. Ten major problems currently faced by the blockchain industry and their analysis

2.1. Is the data on the blockchain really immutable?

Can one of the core features of blockchain, "anti-tampering", really be realized? And is "tamper-proof" really beneficial?

The report pointed out that the blockchain is not completely immutable and gave three weaknesses of the blockchain:

(2) It may be hacked, and 51% of the chain is controlled by people who want to tamper with the results.

(3) The "garbage of garbage" problem has existed for centuries. The value of a blockchain depends on the data on the chain, and data entered into the blockchain may be inaccurate or fraudulent. One solution is to use sensors instead of manually entering data.

The so-called "51% attack" is to take advantage of computing power to cancel payment transactions that have already occurred. If someone has more than 50% of the computing power, he can find the random numbers needed to mine the block faster than others, so he actually has the absolute and effective right to decide which block. From a technical level, a 51% attack is achievable, but the cost is very high for the earliest cryptocurrencies such as BTC. They have built a huge network, which is why BTC’s network has remained stable for 10 years. reason. But with other counterfeit currencies, the risk is greater.

In addition, there is no direct benefit for the attacker to simply launch a 51% attack, and it must be linked to specific short selling and false recharge. Specifically, it is often a double spend on a certain transaction. The attacker stops attacking once. Continuous attacks are costly and will stop once successful; second, the community can issue an emergency pudding and add checkpoints to the blockchain. The community urgently agreed that the attacker’s blockchain was invalid. Therefore, there are many ways to deal with the 51% attack, and it will not be the end of the world for a blockchain.

2.2. Who owns and maintains the blockchain? And who asked about the appearance?

Responsible for problems and losses?

Since the blockchain is a decentralized user community, who will maintain it? Shouldn’t it require human adjustment and maintenance just like a website?

For permissioned chains,For example, alliance chains and private chains do not require incentives such as tokens to motivate people to manage. There is a manager who manages the entire network. Since there are fewer users in the network, coordination costs are relatively low. However, such networks are susceptible to security challenges, and as the number of network users increases, coordination costs will increase.

For consortium chains and private chains, since they are still very centralized organizations, the verification nodes are identified by the organization itself, so the management model is not very different from traditional centralized institutions. However, for public chains, there is no leader who coordinates the entire network system, and only relies on token incentives to coordinate different interest groups, which undoubtedly increases the instability of the entire ecosystem. At present, the development of the blockchain industry is in a very early stage. In addition to the relatively mature decentralized governance of BTC, in the governance of public chains such as ETH and EOS, the founder development team plays a very core role and is the "rules" of the public chain. "Maker", although the entire ecosystem has achieved partial decentralization, the founders still play a pivotal role in the direction of strategic development. Therefore, the author believes that the decentralization of blockchain can only be an ultimate goal that is constantly approaching. From the birth of the project to its maturity, its degree of decentralization should continue to increase, as shown in the figure below. In the early stages of project development, the founder and his development team play an absolute guiding role in the entire ecosystem. As the project ecosystem matures and the number of participants continues to increase, the original development team should gradually weaken its guiding role. The entire network maintenance needs to be decided jointly by all developers and users in the ecosystem. As for the final network problems, they can only be borne by all participants.

Figure: Schematic diagram of the relationship between the degree of centralization and development stages of blockchain projects

2.3. Are smart contracts really smart?

The second reason why smart contracts are not yet that smart is that their entries can be manipulated by evil actors, such as contracting parties or miners who add transaction records to the blockchain's ledger of past transactions. One study showed that 3.4% of ETH smart contracts are vulnerable to hackers.

Smart contracts can indeed optimize many intermediate programs, but judging from current industry practice, they are far from being called smart. A qualified smart contract should include all possible scenarios. Because the core essence of smart contracts is "to make the most just ruling even in the darkest environment."

The difference between Ethereum and Bitcoin is that Ethereum is Turing complete, and more types of contracts with more complex terms can be implemented through this platform. Of course, the cost of this is that the complex contract content makes it becomes more difficult to analyze. Typically, complexity is directly proportional to the probability of a vulnerability; the higher the complexity, the greater the probability of a vulnerability.

As for the concept "code is law" proposed by Ethereum, however, the code has attracted hacker attacks due to its own vulnerabilities, so it is not enough to form the authority of "law". Therefore, it needs the trust and endorsement of the government, lawyers, courts and other intermediary institutions. Compared with coordination, the current contract seems too rough.

2.4． Is there identity theft on the blockchain?

3% of social media accounts are fake, so can fake accounts be created on the blockchain? Can identities on the blockchain be stolen?

Blockchain can create a personal database for users whose data cannot be tampered with, but how to meet the user's "tampering" needs? This may be a paradox in the development of blockchain technology. Regarding user needs, we may need to start from the perspective of on-chain standards and authority management.

2.5． Can blockchains be connected to each other?

One blockchain records the data of an entity or user in one way, while another blockchain records the same data of the same entity or user in another way. In a fragmented system, multiple account books are not connected to each other, which will form a world of "operational islands", or "data islands". Users need to register for multiple systems at the same time to conduct transactions with different people for different purposes.

In view of the value transfer needs of different chains, cross-chain technology is the key, which can effectively connect different alliance chains or private chains, and promote the outward expansion and connection of blockchains. The current mainstream cross-chain technologies include Notary schemes, Sidechains/relays, Hash-locking, Distributed private key control, etc.

2.6. How does the blockchain connect to off-chain databases?

If one party's data and documents are off-chain, and the other party's data and documents are on-chain, can the two parties interact? In the company's database, can half of the company's data on the blockchain interact with the other half of the data?

These challenges are well known and are being addressed. For example, the same queries and analysis can be run in on-chain and off-chain databases. The risk is that data brought from on-chain to off-chain is no longer immutable, and researchers recognize that data security and aggregating, transforming and optimizing on-chain and off-chain data sets are significant challenges.

2.7. Can blockchain facilitate money laundering?

Money laundering is a huge global problem, amounting to 1-2 trillion US dollars, accounting for approximately 2% - 5% of the total global GDP. Banks and authorities are fighting back, spending about $8 billion a year to combat corruption. Banks around the world require KYC verification.

Due to the anonymous nature of the blockchain, especially the emergence of anonymous coins, BTC has been criticized by many people as a tool for money laundering. However, the anonymity of BTC is only anonymity on the chain. The interaction between people and the chain, and the interaction between BTC and legal currency will leave traces, and it is not as "lawless" as many media have promoted. Each BTC transaction requires the transfer of a corresponding address, and the transaction records of the address can be queried. In addition, the exchange of BTC and legal currency is conducted off-chain and cannot escape supervision. If the actual identity of any party in the transaction is exposed, then all parties involved in the transaction will have difficulty escaping recourse.

2.8. districtWill the blockchain consume all the energy in the world?

BTC has an amazing energy demand. Operating Bitcoin for one year requires the energy consumption of Ireland for one year. Because BTC’s POW consensus mechanism requires miners to mine for transaction verification. There are concerns that as the network increases and the value of BTC rises, energy demand will grow rapidly. In fact, miners themselves have incentives to prevent this from happening, and the scalability of the blockchain is limited by availability, energy costs, and the miners' own financial resources. The current alternative is the POS consensus mechanism. The POS mechanism selects validators based on the number of currency holders.

In fact, it can be seen that except for the early batch of cryptocurrencies headed by BTC, the vast majority of current blockchain projects have taken into account the disadvantages of POW and are constantly innovating consensus mechanisms to avoid excessive consumption of energy. Therefore, blockchain is not enough to cause such a huge consumption of energy.

2.9． Will blockchain take our jobs?

Regarding blockchain, if people can trade directly with each other, what impact will blockchain have on intermediaries such as banks and lawyers? Blockchain is unlikely to be a job killer; it will, like any technology, change the nature of work by changing companies’ business and revenue models.

When artificial intelligence becomes popular, people will continue to ask questions like this. On the one hand, we enjoy the convenience that technology brings us, but on the other hand, we are worried that technology will replace us. The biggest challenge of blockchain is not the technology itself, but changing the traditional profit distribution model. Blockchain technology can remove certain intermediary links, break the monopoly of many resources by centralized institutions, and thus change the interest pattern. This is also the most revolutionary point of blockchain.

2.10． Is the United States lagging behind in the development of the blockchain industry?

Globally, the blockchain industry in the United States is still in its infancy. Deloitte surveyed 1,053 executives in financial services, healthcare, technology industries, telecommunications, manufacturing and other industries in 2018. According to the survey, only 14% of American respondents believe that blockchain is used in their production, compared with 49% in China, 48% in Mexico, 40% in the United Kingdom, and 36% in Canada. Plans are also lagging: 41% of U.S. companies plan to invest $1 million or more in blockchain, compared with 85% in China, 74% in Canada, 72% in the United Kingdom, and 65% in Mexico.

According to the "Blockchain China-U.S. Development White Paper" released by Silicon Valley Insight, North America is comparable to Asia in terms of the number of ICOs. In terms of financing amount, North America is far ahead with 7.85 billion. Therefore, the United States, as a major country in North America, is not lagging behind at all. On the contrary, it is still leading in many aspects.

Related questions and answers: What are the uses of blockchain technology in the business field?

What are the uses of blockchain technology in the business field?

In recent years, due to the virtual digital With currency speculation booming, blockchain, as its underlying technology, has also begun to receive widespread attention. Blockchain has the characteristics of decentralization, trustlessness, collective maintenance, and reliable storage. It is currently widely used in the field of virtual currency.

Since the birth of Bitcoin, more than 1,600 virtual currencies have appeared in the world, and a huge industrial chain ecosystem has been formed around the generation, storage, and trading of virtual currencies. But overall, the industry is still in its infancy and is still far away from the real value use area. The core of the blockchain economy lies in the reconstruction of business logic and organizational forms, so it is necessary to obtain practical examples in multiple industries to demonstrate its value. This article will explore the business models used by blockchain in various industries from the perspective of combining blockchain with industry needs.

First of all, the core of blockchain is to solve the problem of credit:

Credit is the foundation of all commercial activities and finance. The United States has implemented trusted identification since 2011, while China has implemented a real-name system to achieve supervised information dissemination. The significance of blockchain is that it has established decentralized trust from a technical level for the first time and realized a completely distributed credit system.

Secondly, blockchain solves the problem of value exchange:

Traditional networks can achieve point-to-point transmission of information, but cannot achieve point-to-point transmission of value. Because information is allowed to be copied, and value must be authentic and unique, it is necessary to rely on a centralized organization to achieve value transfer. Blockchain perfectly solves this problem and provides a method to realize point-to-point transfer of value. During the value transfer process, accounting is realized by the network without relying on a centralized institution. Therefore, blockchain is expected to become the infrastructure for building new finance and the cornerstone of the future value Internet.

The use of blockchain

There are currently two main modes of blockchain use:

1) Native blockchain use: directly based on decentralized blockchain technology to realize value Transmission and transaction use, such as digital currency;

2) "Blockchain +" model: combine traditional scenarios with the underlying protocol of the blockchain to improve efficiency and reduce costs. It is expected that the use of blockchain in various industries will be dominated by the second model.

Blockchain has five core attributes, namely: transaction attributes (value attributes), certificate attributes, trust attributes, intelligence attributes, and traceability.Attributes. The above core attributes are combined with the needs of the industry to solve the industry's pain points and become the business model used by blockchain in various industries.

Blockchain + Bank

1. Cross-border payment

Cross-border payment is a pain point that has long plagued the banking industry. Traditional cross-border payment methods include two major categories: one is online payment, including electronic account payment and international credit card payment, which is suitable for small retail amounts; the other is the bank remittance model, which is suitable for large-amount transactions; both have payment cycles Long, high fees, low transaction transparency and other issues. Especially in recent years, with the rise of cross-border e-commerce, convenient, fast, safe and low-cost cross-border payment has become an urgent need for the industry.

The role of blockchain:

The characteristics of blockchain are deintermediation and open and transparent transactions. There is no third-party payment institution to join, which shortens the payment cycle, reduces fees, and increases transaction transparency. For example, in December 2017, China Merchants Bank teamed up with Wing Lung Bank and Wing Lung Shenzhen Branch to successfully implement cross-border RMB remittances between the three parties using blockchain technology. Its clearing process is safe, efficient and fast, greatly improving customer experience.

2. Supply chain finance

The pain points in this field are the long financing cycle and high costs. Centered on the core enterprise system of the supply chain, it is difficult for third-party credit enhancement institutions to authenticate the authenticity of various relevant vouchers in the supply chain, resulting in long manual review times and high financing costs.

The role of blockchain:

Blockchain introduces consensus mechanism, existence proof, non-tampering, traceability and other characteristics into supply chain finance, and does not require third-party credit enhancement agencies to authenticate various relevant credentials in the supply chain. authenticity, thereby reducing financing costs and shortening the financing cycle. For example, in April 2017, the listed company Yijian and IBM China Research jointly launched the blockchain supply chain financial service system "Yijian Block". The system focuses on pharmaceutical scenarios and currently has more than 30 pharmaceutical distribution companies. Successfully registered in the "Yijian Block", as of the end of July, the number of transactions had been close to 8,000, and the total investment amount exceeded 100 million yuan.

3. Digital Bills

The pain point of the digital bill industry lies in the long-term problems of "false bills" and "one vote selling many", which have brought risks to the bill financing business of the banking industry.

The role of blockchain:

The existence proof and non-tampering characteristics of blockchain effectively solve the problem of false digital bills; at the same time, blockchain solves the double-spend problem and avoids "one vote". Sell ​​more". For example, Shenzhen Blockchain Financial Services Co., Ltd. issues bill chain products to provide bill financing services based on blockchain to solve the bill financing needs of small, medium and micro enterprises. Cooperative banks include Ganzhou Bank, Guiyang Bank, Suzhou Bank, Shizuishan Bank, Langfang Bank, Wuhai Bank, Jilin Jiutai Rural Commercial Bank, Yaodu Rural Commercial Bank, Shenzhen Rural Industry Bank, Weifang Bank, Zhongyuan Bank, etc. In addition, Zheshang Bank, JD Finance, Hang Seng Electronics, HNA, etc. are also verifying blockchain digital bill services.

Blockchain + Securities

1. Asset Securitization

Asset securitization uses future income asGuaranteed to get financing now. The pain points in this field are: there are many participating entities, many operating links, low transaction transparency, information asymmetry, and the authenticity of the underlying assets cannot be guaranteed.

The role of blockchain:

Blockchain introduces attributes such as existence proof, non-tamperability, and consensus mechanism for asset securitization. It can monitor the true situation of assets in real time and solve the problem of the underlying issues of institutions in the transaction chain. Asset trust issues. Various assets such as equity, bonds, bills, income certificates, warehouse receipts, etc. can be integrated into the blockchain and become digital assets on the chain, improving asset circulation efficiency and reducing costs. For example, in May 2017, Internet Finance and partners including Baiqian Leasing and Huaneng Trust jointly issued an asset securitization ABS project supported by blockchain technology, with an issuance scale of 424 million yuan.

Blockchain + Insurance

1. Insurance Business

The insurance industry has problems such as information asymmetry and lack of trust between customers and insurance institutions: it is difficult for users to choose insurance products that suit them, while insurance institutions Face the risk of insurance fraud.

The role of blockchain:

The decentralized, open, transparent, and traceable characteristics of blockchain establish a good communication channel between insurance institutions and users; insurance subject information is managed uniformly on the blockchain , cannot be tampered with, helping insurance institutions avoid the risk of insurance fraud; at the same time, smart contracts can improve work efficiency and reduce costs. For example, French insurance giant AXA is using the Ethereum public blockchain to provide automated flight delay compensation for air travelers. If the flight is delayed for more than 2 hours, the "smart contract" insurance product will automatically pay claims to passengers.

2. Credit information management

The pain point in this field is that credit information agencies have limited data collection channels and a lack of data sharing, which makes it difficult to accurately characterize the credit status of individuals or institutions; in addition, there are also problems in how to guarantee the data collection process. User privacy issues.

The role of blockchain:

Blockchain has the characteristics of trustlessness, consensus, and non-tampering. At the technical level, it ensures that limited and controllable credit data sharing can be achieved on the basis of effectively protecting user privacy. And verification. For example, Ping An's blockchain credit reporting business is now online. In addition, domestic startups such as Shanghai Juzhen, LinkEye, Bubi Blockchain, etc. are also exploring joint credit reporting and safe certificate storage.

As a basic technology, blockchain has great use value in many industries with distributed processing, peer-to-peer transactions, and rapid establishment of trust relationships. Its core is to solve the problem of credit and realize Point-to-point delivery of value. Therefore, it is considered to be the cornerstone of the future value Internet.

The core of the blockchain business model is to use the innovative attributes introduced by the blockchain and combine it with traditional industry uses to realize the reconstruction of business logic in order to create new usage scenarios, or improve efficiency and reduce costs.

It is expected that the use of blockchain will first start in the pan-financial field that has high requirements for credit, efficiency, and security: the financial industry pays more attention to efficiency and security, and the matching of blockchain with its pain pointsIt is relatively high and can systematically solve the trust issues, efficiency issues, default risks, etc. that exist in all aspects of financial services; the blockchain’s attributes such as “transaction, certificate storage, and traceability” are more likely to generate value in the financial industry. At the same time, the market space in the financial industry is huge, and small progress can bring huge benefits.

Blockchain will also extend to all areas of social life: Blockchain solves problems such as the management, transaction, and transfer of digital assets, and therefore will play an important role in the wave of asset digitization, such as supply chain management, data Applications such as services, asset management, public services, and the Internet of Things are gradually being implemented in various fields, and "blockchain+" is becoming a reality.

10. Blockchain Case｜Being like a rat with Peking University behind your back—difficult!

The story starts with the blockchain project. We know that many of the founders of blockchain capital have backgrounds in prestigious universities, especially Beijing University, Qingdao University and top foreign universities. This is not accidental. , as far as I know, entrepreneurs or partners are much more diligent than you think. Of course, most of them have good educational backgrounds, and they will naturally pay attention to trends.

However, a small number of capitalists like to use their educational background to sugar-coat their jobs in Gaofu.

Why? I believe you and I both know it clearly but have not said it or it is difficult to explain it.

Today, let’s take the Hero Entertainment Chain, which has been widely infamous in the chain currency circle for more than half a year due to air currency, as an example:

The Hero Chain public account has been suspended for more than a year.

"In May of this year, CCTV News directly named the Hero Chain project, accusing it of committing false fraud in the name of tokens. As the sales director of Hero Chain, Peking University talent Liu Hongyuan became the target of public criticism after the incident. .

After the incident, Liu Hongyuan ran away to Singapore, and Hero Chain CEO Gao Zhun also led his team to Cambodia." - The little monster next door.

What is the Hero Entertainment Chain? Who are the people on the platform?

"Hero Chain (HEC) was launched in January this year. It is a gambling game platform that supports digital cryptocurrency. The project CEO is Micro Motion."

Hero Chain White Paper:< br />
Who is Liu Hongyuan, and how did he get involved in the hero chain?

Liu Hongyuan, former president of Peking University Venture Capital Research Association. As an angel investor, Chen Manli had an educational background at Tsinghua University that could easily connect with college students. She took a fancy to Liu Hongyuan, who was anxious about starting a business.

“In addition to Liu Hongyuan, people who participated in proxy investment include Wang Dapao, Mr. Bai, Bit Wu, etc. These people have contributed to the sales of Hero Chain.”
< br />As can be seen from the white paper, Hero Chain tokens are stipulated not to be circulated within one year and will be locked. Funds raised are used for development.

The manipulator behind the Hero Chain Entertainment Chain is actually Hash Capital Chen Manli.

So, who is Chen Manli?

She works in ten companies including Dream Peak Technology Co., Ltd., and holds senior management positions. There is also Tsinghua Macquarie Master of Applied Finance, which can connect university students as teachers..

Hash Capital where Chen Manli works - background introduction

Hash Capital is a digital asset investment research institution co-founded by Mr. Deng Deyan and Mr. Nick.Fu (Fu Xiaoming). The founder, Deng Deyan, holds a master's degree in applied finance from Tsinghua Macquarie. He was a foreign exchange analyst at a well-known Australian financial institution and has many years of experience in securities foreign exchange and spot trading. Mr. Fu holds double degrees in law from Renmin University of China and communications engineering from Wuhan University of Technology.

Hash Capital and Asia-Pacific Blockchain Business Applications

Hash Capital has raised 3 funds since its establishment, totaling tens of millions of dollars, focusing on the Asia-Pacific market Blockchain business applications and digital asset-related projects. The projects invested by Hash Capital have gradually formed a coverage of the entire blockchain industry chain, including smart contracts, securities transaction settlement, identity certification, distributed accounting, e-commerce, data API and blockchain infrastructure and other fields. Investments include IPTChain, KTrade, Loopring, Qcash, CoinMeet, Halal Chain, Nuls and many other high-quality digital assets.

Comments on mutually reinforcing each other:

Long titles are normal among project founders. After all, blockchain projects do not necessarily require an actual company, and a chocolate office like the Newton project is acceptable. How founders make themselves known to investors is a problem. Therefore, the founders of each project party will have separate titles. People who have experience leading projects are more likely to win the trust of investors.

Create a conversation that is not a joke:

"What do you have?"

"I have a Title."

This shows the importance of titles in the blockchain industry. Dialogue is dialogue, and the founders of the project are still very capable and have professional knowledge background.

From the perspective of covering the entire investment industry, it gives people a professional and grand feeling. It is such a tall-looking organization that hides Chen Manli, the manipulator behind the Hero Chain Entertainment Chain.

Being like a rat with Peking University on your back—difficult!

Why do Chen Manli and other small capitals like to station themselves in Gaofu and sugar-coat things? !

Peking University has administrative status and potential value in the consciousness of the Chinese people

When talking about Peking University, do you feel the same inexplicable heat in your chest as I do at the moment? You have not received its blessings, but you seem to have received them. Surrounded by great benefits. I want to say more but I'm afraid I won't be able to say enough. Peking University Peking University adheres to the principle of freedom of thought and embraces inclusiveness. Probably because Peking University belongs to the Chinese people, not you and me.

1. Taking Peking University as an example, its administrative status prompts it to not onlyJust a school

.

Peking University once held the status of the capital, starting from the position when Peking University was founded. By definition, it is the only school established as the country’s highest institution of higher learning in modern China. Initially, it was also the country's highest educational administrative agency, exercising the functions of the Ministry of Education and overseeing national education.

It can be seen that the administrative functions of Peking University have historical origins.

Even if you and I don’t remember him for a moment, we think he is an ordinary student or teacher. But some things are really subtle, and many people and rural parents have a brand-like influence on their subconscious minds, just like the widely spread Nainai Temple.

2. Even if the Chinese people’s sentiments about the Peking University and the Qing Dynasty are not deep, they are not shallow either

As a normal Chinese child when I was a child, I believe that everyone was the same, and they must have been instilled with different cultural backgrounds in childhood. But the same meaning was expressed in the eulogy of Peking University, Qingda University, Renmin University of China and other Beijing universities. It is undeniable that I also have feelings for Peking University and Qing Dynasty. These feelings are often for people because the masters gave speeches at Peking University. I don’t have many impressions of Peking University, but it’s not shallow either. This influence was so great that when the top scholar in science in Sichuan Province wanted to describe himself as a three-dimensional person rather than a learning machine, he still chose to write "Peking University is my beautiful and shy dream". In human terms, it was for Peking University. As a PR person, I am well aware of the issue of Peking University’s status in the hearts of Chinese people.

Therefore, it is understandable that Peking University is uneasy at this moment.

She, Chen Manli, is still the same, with the same appearance, a teacher title on her head, and the Global University Blockchain Entrepreneurship Leaders Alliance (the launching ceremony of the Global University Blockchain Entrepreneurship Leaders Alliance is July 25 From 14:00 to 16:00 in the afternoon, the Blockchain Leaders Event (Blockchain Leaders’ Consultants) held in Room 601, Building C, Mingde Building, Renmin University of China, No. 59 Zhongguancun Street, Haidian, Beijing, once again targeted students from Peking University and other universities.

If today’s entrepreneurial teachers and students hold Peking University’s back and want to be like a rat, it’s hard!!!

Because of the rat shit in the Beijing University, Liang Hongzhi, Shi Ping, Zhang Zongxiang, etc. Aren't they just ordinary people? !

If you ask some old alumni of Peking University who are also managers, are they involved in blockchain? Is it true?
