㈠ Blockchain, how to solve the financing difficulties of small and medium-sized enterprises
In recent years, companies arrears with wages and bosses run away have become commonplace in the news. Jokes about "Jiangnan Leather Factory" also appear on social media from time to time. These "news" that are no longer new remind everyone repeatedly that the old problems of corporate financing for many years have become "new" dilemmas that have been unresolved for a long time. I wonder if there is any way to solve the problem. With the development of financial technology, maybe blockchain is bringing new ideas to this old problem?

㈡ The role of blockchain and zero-knowledge proof in the credit system How it works
Zero-knowledge proof in the blockchain plays an important role in privacy protection, and it is no exception in the credit system, but where in the system and in what way does it play a role? A question worth thinking about and studying.
First, credit issues cannot rely entirely on technical reliability. Government authority is sufficient for some issues, such as household registration and identity information. There is no need for further questioning on these issues.
Second, the usage scenario of blockchain evidence storage should be the scenario where there is a long quantitative chain of evidence, such as monthly and annual summary based on flow statistics to ensure that the calculation process of summary is not Fraud. The flow details are in the upstream of the evidence chain, and the time is beforehand. If you falsify upstream, you can falsify months or years in advance. The planning ability of the attacker and the cost of falsification are much higher. To a certain extent, it is economically feasible to prevent fraud.
In fact, this involves the issue of closure of domain events on the chain mentioned above. For areas where it is almost impossible, or where there is no realistic possibility of complete closure in the foreseeable future, the degree of closure is a gray level issue. If you trace it upstream along the logical chain of events and upload them to a certain level, attacks will be impossible. When attackers' attacks become quite or extremely difficult, blockchain applications will generate value and do not require complete closure. In this way, the value field of the blockchain will break through the virtual currency and decentralized financial defi, which are completely closed to the chain. The system can be expanded. This logic is not limited to the credit system, but applies to the general logic of combining blockchain and fields. To give another example, whether the traceability system can achieve the anti-counterfeiting function depends on whether the depth of the traceability in the evidence chain is enough to cause the dilemma of the counterfeiter. Without examining this point, it is only a formal use of blockchain evidence. meaningless.
So we can almost get a theorem:
The value level of blockchain in field applications is directly proportional to the depth of the evidence chain.
Then the second question that follows is: tracing back along the chain of evidence, the further upstream, the closer to the privacy of the subject (citizen privacy or organizational business secrets). The solution to this problem is where zero-knowledge proofs come into play and how they work. The application value of many zero-knowledge proofs is unclear. Now we consider it in the context of the evidence chain and it will become clear:
1. Zero-knowledge proofs are used to process quantitative evidence. During the chain traceability process, traceability is completed without revealing the clear text details of the upstream evidence chain, which not only plays the role of blockchain traceability along the evidence chain, but also protects privacy.
2. For scenarios where traceability is not necessary, the evidence chain does not exist, and the role and significance of zero-knowledge proof are also unclear. For example, for general identity and household registration information, administrative authority should be considered credible and there is no need to trace it back. Note that the evidence chain mentioned here is not a causal relationship in the physical sense, but a value trade-off through system application goals.
To summarize:
1. Use blockchain technology to retain the upstream of the evidence chain. 2. The further upstream the evidence chain is, the closer it is to citizen privacy. Use zero-knowledge proof to protect privacy
1. Refer to zkledger of MIT Media Lab and use blockchain combined with zero-knowledge proof to deal with citizens and organizations Summary reporting issues of financial and taxation processes.
2. The technical problem that needs to be solved is that in the zkledger scenario, there are only a few large transactions of a few banks, and the amount of data is small. However, when used in individual citizen scenarios, the amount of data is huge and requires Find ways to resolve performance issues.

㈣ Why blockchain technology is said to convey credit value
Blockchain has the advantages of decentralization, non-tampering, trustworthiness, traceability, and network-wide accounting.
The most important thing about blockchain is that it solves the problem of intermediary credit. In the past, it was difficult for two people who did not know and trust each other to achieve collaboration, and they had to rely on a third party. For example, in payment behavior, any kind of transfer in the past required the existence of an institution such as a bank or Alipay. However, through blockchain technology, Bitcoin is the first time that humans have realized the transfer behavior that both parties can trust without the participation of any intermediary agency. Guarantees, loans, credit, risk control, equity, income, and ratings based on blockchain are all possible. The value Internet attributes of blockchain enable various economic activities to run more efficiently. Whether it is ordinary people in society or various economic people, it will be mapped to a "blockchain ID" to form a new moral system, evaluation standards, credit records, etc.
㈤ Blockchain Discover the pain points of users and cut in at the right time. There are many cases of subverting traditional industries. In the blockchain era, as technology becomes increasingly mature, there are more opportunities to achieve subversive innovation in multiple industries by "resolving trust"; even the "Internet" feels that The difficult car maintenance industry is beginning to be subverted by "blockchain". What else is impossible?
Niu Wenwen, founder and chairman of Dark Horse Academy, often says that "all business in China is worth doing again." Niu Wenwen's words are more about Internet people, and they also describe the new opportunities brought by the Internet's transformation, impact, and transformation of traditional industries. In the process of providing "solutions" to traditional industries, many Internet people continue to discover the pain points of the industry. Many people have solved the "predecessors" in this industry and become famous in the world.
1. In "providing solutions", Internet cases that subvert traditional industries.
1. Before the establishment of Flash Delivery (a new express delivery model that provides users with direct delivery and time-limited intra-city delivery services), the team mainly provided SAAS software services for domestic express delivery companies. Help express companies provide technical support and "solutions". While providing "solutions" to many express delivery companies, I discovered a gap in the market for "same-city" express delivery, innovated the model, and became famous in one battle. Up to now, there are more than 700 members in the Shanshuo team, with services covering 177 cities, more than 78 million users, and more than 410,000 Shanshuang employees.
2. Before the establishment of Aijia Life (creating a one-stop home decoration service platform by integrating social resources such as real estate, designers, brand hard decoration, and brand home furnishings, focusing on a simple and high-quality lifestyle), The team mainly provides CRM customer management system software services for real estate developers. When cooperating with real estate developers for a long time and providing "solutions", they discovered the industry pain points in the home decoration market. With the help of long-term cooperation resources in real estate, we started the "Home Decoration 3.0" era. , less than 3 years after its establishment, the contract value exceeded 10 billion, causing great ripples in the home decoration industry.
Although we can find many such cases. BUT, in some industries, even if Internet people try hard and try one after another to subvert through "Internet +" or "+Internet", most of them fail. In which industries? They are those industries where the "trust crisis" is serious and cannot be broken through and alleviated by Internet technology alone.
2. By “resolving trust” to disrupt and innovate many industries, “Blockchain ⅹ” will stimulate great vitality.
Before the emergence of blockchain, there were only three types of credit systems in the world. The first was based on morality, which relied on moral constraints to solve the problem of trust. The second is based on faith. Because Christians believe in God and rely on a common belief, they have established a credit system. The third is the system design based on the government. We all rely on the credibility of the government as the backing. Based on these three systems, it is always difficult to form a closed loop for certain industries or certain links in the industry. The so-called "pain points" solved by Internet people are all based on staged and specific scenario transformation and subversion.
With the emergence of blockchain, there is a new cornerstone of the credit system in the world---algorithm, which has a characteristic, which is consistency. No matter the time or place, as long as the input is determined and the algorithm is used, the output will be determined. The new credit system established by blockchain based on this characteristic has created new opportunities for change in many industries such as finance, energy, government, medical care, copyright, Internet of Things, agriculture, charity, etc. Following the supervisionAs management standards, industry standards, and technological maturity continue to improve, the blockchain industry bubble will gradually disappear and accelerate into a new stage of close integration with the real economy. If the blockchain 1.0 and 2.0 eras are called "blockchain+", then the 3.0 era should be called "blockchainⅹ", which will promote the transformation of the entire social pattern more efficiently.
3. The automobile maintenance industry will be subverted by "blockchain", what else can't be done?
Take the automobile maintenance industry as an example. "Trust" has become a pain point that is difficult to break through in the industry. Information in the industry chain is opaque; manufacturers and distributors cannot grasp accurate data on market consumption and inventory; repairers cannot find suitable accessories in massive inventories, making ordering difficult and delivery slow; consumers cannot find high-quality repair stores. It takes time and effort. China's automotive aftermarket is worth trillions. Internet giants such as Alibaba and JD.com have invested heavily in the market, but have had no trouble and mediocre results. Internet people have never been able to solve the "crisis of trust" in the automotive aftermarket. Breakthrough.
CarFix, as the issuer of the Vehicle Lifecycle Blockchain Token (VLB), hopes to guide many automobile manufacturers, dealers, repair shops, insurance companies, parts dealers, etc. Players in the cyclical industry enter a new "era" and hope to, in the company's words, "change the face of one of the world's most outdated industries." Developing and building a blockchain platform to bring transparency and record immutability to the automotive lifecycle industry - data from the first time a car is assembled on the factory floor, all the way to the time it is recycled in the junkyard The entire process is transparent and cannot be changed. Using this blockchain to perform routine maintenance work builds consumer trust in maintenance personnel.
CarFix claims that it has created an ecosystem of trading software platforms, repair shops, spare parts suppliers and dealers. In this system, any repair work can be immediately priced through an algorithm, the algorithm and the price are transparent, and the maintenance service can be booked as easily as booking a hotel room. Its ecosystem currently includes more than 500 repair shops, the 10 largest spare parts distributors, main dealers and more than 250,000 users, 50,000 of whom are regular paying customers. This ecosystem is clearly still thriving and will further enhance blockchain’s core capabilities of decentralization and immutability of records. In essence, blockchain tokens are endorsing industries that were once considered “untrustworthy” and helping them regain the trust of consumers.
With the smooth development of public chains such as EOS and AE, we can foresee that there will be more D that are based on application scenarios and solve real-life problems.Once the APP is launched, blockchain will soon penetrate into every corner of our lives and be integrated with our lives. Fortunately, as of the end of March this year, the number of blockchain companies in my country with blockchain as its main business reached 456, and the industry has initially formed a scale. As the innovation and development of blockchain technology gradually matures, blockchain applications have extended from the financial field to the physical field, including electronic information storage, copyright management and transactions, product traceability, digital asset transactions, Internet of Things, intelligent manufacturing, supply In areas such as chain management, a number of “industrial blockchain” projects have been formed.

㈥ What are the issues that need to be improved in blockchain applications
2018 is the first year of the blockchain, but the world's overall blockchain industry, except for the financial industry, is still in its infancy. The maturity of the blockchain industry requires the integration of a series of factors such as technology, market, supervision, and popularity. According to the current development of the blockchain Momentum, experts predict that large-scale implementation can be achieved within 3 to 5 years, and the real economy will also have a new development model. What are the issues that need to be improved in the application of blockchain?
Accelerating the implementation of blockchain technology in industrial scenarios still needs to focus on
1. Quick matching of application scenarios.
Use Blockchain technology can effectively solve the pain points of the industry market. In the mainstream B2B transaction mode scenario of the market, it is easier to combine using blockchain technology. If the application scenario meets the conditions of high transaction frequency, fixed transaction scope, insufficient credit, etc., blockchain technology can be easily implemented This scenario. In the future, as the foundation of blockchain technology matures, it will gradually be applied to more transaction models.
2. The technology is further improved.
Blockchain technology is currently perfect Insufficient strength, 51% computing power attack problem, double-spending gap problem, high transaction costs, low TPS throughput, transaction block chain selection problems, excessive energy consumption of the POW consensus mechanism, hacker intrusions and other technical obstacles.
3. The industry mechanism is sound.
Accurately distinguish the relationship between centralization and decentralization. Decentralization means that the entire operating system can operate autonomously under the condition that there is no central agency management. Two strangers Under decentralized conditions, individuals can achieve trust and realize transaction facts at low cost and quickly. However, what is clear is that the ecosystem is not unmanaged, and the blockchain is still the information center and requires constant technical support. , repeated upgrades, there is a certain centralized mechanism behind it.
㈦ Blockchain 100 - Zhou Kaiyu: Can blockchain credit innovation break industry credit barriers
Hazel Mr. Zhou Kaiyu, CEO of Xing Technology
Currently, credit reporting has become a key part of the credit system and forms an important support in the operation of the modern financial system. There are certain difficulties and pain points in traditional credit reporting, and the decentralized and non-tamperable characteristics of blockchain will change the insufficiency of data privacy protection involved in the credit reporting process in one fell swoop.Consensus trust issues in the data sharing transaction process.
Mr. Zhou Kaiyu elaborated on the advantages of the combination of blockchain and credit reporting, and described the development status of the blockchain credit reporting industry at the legal level. At the same time, he expressed his views on the future development of Zhenxing Technology and the future direction of blockchain innovation.
Zhenxing Technology is positioned as a blockchain value ecological enterprise and is committed to building the next generation of trusted application service basic network based on blockchain. In June 2017, the company established a stable team structure and carried out related technical matters. From July to August, the first version of Zhenxing’s technical white paper was completed. At present, Zhenxing has implemented the first version of the system and has also started to provide related services in terms of blockchain-based identity verification. In the later stage, further development based on the second version of the credit evaluation system will be carried out.
In terms of ecological construction in the future, Mr. Zhou Kaiyu said that the blockchain credit industry has both value and opportunity. He hopes that industry partners with some high-quality resources on the B-side in the early stage can jointly expand services and eventually achieve A large number of users gather on the C-side, creating an ecological environment for high-credit preference transaction customers. In terms of the company's development plan, Zhenxing will break the inherent thinking of traditional blockchain anonymous verification, build a decentralized strong identity verification basic network, and integrate a trusted Internet service ecosystem.
The original intention of choosing a project that combines credit reporting with blockchain
“Choose blockchain to develop because it has a community-based approach that maintains the stability of the entire system. Consensus reward, consensus reward is a process of social value redistribution. In the process of social value redistribution, a value effect is formed in which the wool comes out of the pig and is paid by a third party. While achieving credit value, it can It is a means to encourage everyone to maintain high credit." Mr. Zhou Kaiyu said.
According to Mr. Zhou Kaiyu, in the traditional credit reporting process, data is processed in a traditional centralized way. The data exists on a centralized platform, but it is difficult to verify the security of user data. The issue of personal privacy data has attracted attention from society, government, enterprises and other levels. Blockchain will form a combination with blockchain through the credit alliance.
At the same time, the Block Hall Chain can combine some personal security mechanisms to achieve comprehensive and strict protection of personal privacy data and complete credit reporting services with authorized attributes. Zhenxing’s credit reporting service combines the advantages of blockchain, using personal data and individuals themselves to provide diversified credit reporting services through data services.
What are the advantages of the combination of blockchain and credit reporting?
When it comes to the combination of blockchain and credit reporting, its main core lies in the data level, since credit reporting uses a large amount of user data. In a decentralized system like blockchain, data needs to be maintained jointly by everyone. It is difficult for anyone to change the data. This canThe security of user data is clearly guaranteed. Any data access must be authorized by the user.
Regarding the current legal status of blockchain credit reporting, Mr. Zhou Kaiyu introduced, “In terms of credit reporting, the country has many management regulations to regulate the processing of customer data by enterprises. Blockchain + reporting In terms of information, it is a very good technical method." In his view, “Blockchain + credit reporting has become the only basic technology that can fully meet all requirements in terms of privacy protection when most technologies cannot meet the needs of credit reporting.”
< br />What are the options for future blockchain innovation directions?
Mr. Zhou Kaiyu said that the development of blockchain is still in an early stage, and there is huge room for future innovation in blockchain. Currently, we are optimistic about the direction of innovation, such as asset digitization. Asset digitization will be a relatively long process, and various applications will continue to emerge during development. In terms of technological innovation, blockchain still has a lot of room, and more attempts are being made in new directions of upgrading and balancing.
Zhenxing hopes to build a value exchange ecology with high performance value, and hopes that under its nourishment, everyone will be happy to maintain their personal credit, and everyone will be able to participate in the credit transaction process. gain from it. The future development of Wuxiaokai will be based on the core concept of maintaining high credibility and combating dishonest people.
㈧ What kind of problems can blockchain technology solve?
What kind of problems can blockchain technology solve? Blockchain technology can solve the trust problem at a relatively lower cost, which plays an important role in the current emphasis on reducing the burden of the real economy and reducing transaction costs, and has great social value. At the same time, there is still a need for continuous exploration of the blockchain technology itself. It is believed that independent controllable intellectual property rights and patents can be integrated with this technology in the future.
In the future, Jinwowo will focus on promoting the legal circulation and commercial application of big data using blockchain technology.
Jinwowo analyzes the problems that blockchain technology can solve as follows:
The most important thing about blockchain is that it solves the problem of intermediary credit. In the past, it was difficult for two people who did not know and trust each other to achieve collaboration, and they had to rely on a third party.
For example, in payment behavior, any kind of transfer in the past required the existence of an institution such as a bank or Alipay.
However, through blockchain technology, it is the first time that humans have achieved a transfer behavior that both parties can trust without the participation of any intermediary agency. This is a major breakthrough for blockchain.
Analysis by Chongqing Jinwowo: The most important thing about blockchain is that it solves the problem of intermediary credit.
In the past, it was difficult for two people who did not know and trust each other to achieve collaboration.Yes, you must rely on a third party.
Chongqing Jinwowo analyzes the problems solved by the application of blockchain technology as follows:
The most important thing about blockchain is that it solves the problem of intermediary credit. In the past, two people who did not know and trust each other had to reach an agreement. Collaboration is difficult and requires a third party.
Through blockchain technology, it is possible to complete behaviors in which both parties can trust each other without the participation of any intermediary agency. This is the problem solved by disintermediation (decentralization) in blockchain technology.
Blockchain solves the problem of trust, which is the root of all problems.
WaykiChain is a smart contract platform that supports Turing completeness. WaykiChain adopts the dpos consensus mechanism, with a total of 11 voting nodes, which generate a new block every 10 seconds. Through smart contracts, WaykiChain can realize rich application scenarios such as asset issuance, betting applications, copyright traceability, mutual insurance, decentralized exchanges, and cross-border settlement.
But the most important thing in these scenarios is trust and openness and transparency.
What problems can blockchain technology solve?
Based on mechanisms such as distributed accounting, collective contracts and intelligent consensus, blockchain technology presents information processing characteristics such as decentralization, open sharing, authenticity and reliability, which has triggered increasing attention and attention in the financial field, especially in the Internet financial field. Research applications. There are many blockchain system development companies. Blockchain technology development companies like Renren Chain are relatively reliable. You can refer to blockchain solutions.
Point 1: First of all, you must understand the technical strength of the blockchain technology service provider you choose, including the underlying strength of the blockchain and the technical strength of the team; what successful cases have been developed. Ask for developed projects, and the other party will analyze previous successful cases.
Point 2: It depends on the other party’s existing underlying blockchain architecture and project development experience.
Point 3: You can ask your friends if they know anything about it and recommend it. I personally know that the Renren blockchain BaaS platform has good overall strength. It can quickly build its own IT infrastructure and blockchain services on an open cloud platform. Of course there are others, choose the platform that suits your business. There are still issues that need attention that have not been mentioned, and I hope others can help add them~
The blockchain is similar to a "public ledger". Each block is a "ledger page". When people conduct transactions on the blockchain, the transaction data will be disclosed to every node in the blockchain, and It is recorded on the "ledger page", permanently stored, and cannot be tampered with. In view of the decentralization, openness and non-tampering characteristics of the blockchain, each work entered into the blockchain copyright registration system will generate a unique digital fingerprint that cannot be tampered with.
Users only need to pass the Xiaoxi Copyright Chain platform identity authentication authorization, and after successfully authenticating "I am me", submit the work to the Copyright Chain. After the background review is passed, the data will be generated and written into the blockchain to generate a certificate. To apply for a paper certificate from the Copyright Protection Center, you need to click "Copyright Certificate Application", then follow the steps to fill in the information, pay the fee, and wait for review... From this point of view, the blockchain + copyright model is really safe, time-saving, and effort-saving.
When it comes to legal protection, we have to mention "infringed" copyright as an intangible asset. If the creator lacks awareness of rights protection, the work may face infringement. Xiaoxi Copyright Chain does this relatively well in the industry. The reason why this platform has become the first smart rights protection platform based on blockchain in China is also inseparable from the support of the Chongqing Notary Office. The digital document storage technology based on the blockchain has been recognized by the notary office and can ensure that the content of the notarization application cannot be tampered with, providing help for the digitization, networking, and informatization of notary services. Notarization parties can submit "preservation evidence" for notarization online through the Xiaoxi platform, making the rights holder's ownership of the work more judicially effective, effectively facing infringement, and improving risk response capabilities.
Blockchain, a new credit evaluation system, provides new technical support for the service reform of notary offices. Xiaoxi Copyright Chain has moved part of the business of the Chongqing Notary Office onto the blockchain platform, which can be called an innovation of blockchain in the field of notarial certificate business. In the process of notarization, material review and verification is the most critical and important part. The process design of the "blockchain + notarization" background changes the previous steps that required manual verification in various departments. Notaries only need to review the materials provided by users online to quickly complete the review and verification work, which greatly improves work efficiency.
The distributed architecture and non-tampering characteristics of blockchain technology can help solve problems such as the authenticity of bills and opaque information. When parties need to verify whether a note has been tampered with or transferred, the blockchain can provide indisputable proof of consistency.
Digital currency also takes advantage of this feature of blockchain. Puyin is a tea-based digital currency developed based on blockchain technology.
Analysis of Chongqing Jinwowo:
First, through its application in the field of digital currency, blockchain provides a solution for the flow of capital flow (or capital flow) information on the Internet.
Secondly, the blockchain solves the problem of confirmation of authority during the transaction process through encryption and reference to distributed ledgers.
Thirdly, the blockchain determines the exchange of digital assets through the technology of consensus mechanism.
㈨ As time passes, what is the core of the blockchain economy?
Since the birth of Bitcoin, more than 1,600 virtual currencies have appeared around the world. Currency, surrounding the generation, storage, transaction, etc. of virtual currencyA huge industrial chain ecosystem has been formed. But overall, the industry is still in its infancy and is still far from the real value application area.
The core of the blockchain economy lies in the reconstruction of business logic and organizational form, so it is necessary to obtain application examples in multiple industries to demonstrate its value. This article will explore the business models of blockchain applications 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 realize point-to-point transmission of information, but cannot realize 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.
Application of blockchain
Currently, there are two main modes of blockchain application:
1) Native type Blockchain applications: directly based on decentralized blockchain technology, realizing applications such as value transfer and transactions, such as digital currency;
2) "Blockchain+" model: combining traditional scenarios with Combined with the underlying protocol of the blockchain to improve efficiency and reduce costs. It is expected that the application 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 a business model for blockchain applications 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 retail small 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 with the rise of cross-border e-commerce in recent years, convenient, fast, safe and low-cost cross-border payment has become an urgent need for the industry.
BlockchainFunction:
The blockchain is deintermediated and transactions are open and transparent. 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 features into supply chain finance, without the need for a third-party credit enhancement agency Identify the authenticity of various relevant vouchers in the supply chain, 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-standing problems of "false bills" and "one vote selling more than one", which have brought challenges to the bill financing business of the banking industry. risk.
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 problem of double Spending money can avoid "one ticket selling too many". 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 as a guarantee to obtain current financing. 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, which can monitor the true situation of assets in real time and solve the problem of The trust of all parties in the transaction chain on the underlying assetsAny question. 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: Users It is difficult to choose an insurance product that suits you, and 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 matter Information is managed uniformly on the blockchain and 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 lack of data sharing, making it difficult to accurately characterize the credit status of individuals or institutions; in addition, There is also the issue of how to protect user privacy during the data collection process.
The role of blockchain:
The blockchain has the characteristics of trustlessness, consensus, and non-tampering. At the technical level, it ensures that effective protection of user privacy can be achieved. Limited, controllable credit data sharing 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 deposits.
As a basic technology, blockchain has great application value in many industries with distributed processing, peer-to-peer transactions, and rapid establishment of trust relationships. Its core is to solve the credit problem and realize the point-to-point transmission 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 applications to realize the reconstruction of business logic in order to create new application scenarios or improve efficiency. cut costs.
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 services, asset management, public services, Internet of Things and other applicationsIt is gradually being implemented in various fields, and "blockchain+" is becoming a reality.
