A. Why SF Express and JD Logistics are accelerating the application of blockchain technology
In the field of logistics, blockchain technology can play a role in traceability, reconciliation, and credit reporting. . It is understood that SF Express uses blockchain in logistics services to compress intermediate links in logistics services and improve the overall efficiency of the industry on the premise of optimizing resource utilization. JD Logistics is also accelerating the deployment of blockchain technology to realize that each product has its own unique blockchain "ID card". At the same time, it also built a blockchain document platform, a blockchain reconciliation platform, and a trusted warehouse receipt service platform, combined with the Internet of Things, AI, and GIS technologies to ultimately realize the digitization of logistics documents, the contractualization of operating rules, and the assetization of logistics data. .
Blockchain has significant advantages such as decentralization, distributed accounting, and encrypted traceability, which can well ensure the integrity and authenticity of on-chain data. Once it has been tampered with or forged, it can be discovered. At the same time, because the blockchain has the characteristics of distributed accounting, even if the data on individual nodes is deleted, other nodes can still completely save the data, ensuring the integrity of the entire blockchain certification system. normal operation. Based on the above advantages, blockchain is naturally suitable for electronic data storage. The introduction of blockchain certificate storage can effectively solve the authenticity and legality issues of electronic evidence, making the electronic data certificate storage process more trustworthy. Future industry trends will develop based on the "blockchain+" model. Yibaoquan uses blockchain technology to effectively solve the whole-link trust issue of electronic data from generation, storage, notarization, and proof: when uploading to the chain, the blockchain is used to ensure the originality and integrity of the storage data. After being put on the chain, each judicial node on the preservation chain is used to ensure the credibility and security of the data; during litigation, the evidence is directly passed to the Internet court to improve the efficiency of rights protection.
B. Interpretation of 2020 JD.com’s second quarter financial report: Technology investment has become the secret to JD.com’s steady growth in adversity
On August 17, JD.com Group released its second quarter financial report: In the second quarter of 2020, it achieved net Revenue reached 201.1 billion yuan (approximately 28.5 billion U.S. dollars), a year-on-year increase of 33.8%. This growth rate not only set a new high for JD.com in the past 10 quarters, but also achieved a single-quarter net income of more than 200 billion yuan for the first time, creating China’s retail and A new record for single-quarter revenue in the Internet industry. In addition, smart logistics has also achieved remarkable results. JD Logistics' "Asia No. 1" smart logistics center in Langfang Economic Development Zone was officially opened. The park is equipped with Asia's e-commerce industry's first automated storage and picking system for large items, which greatly improves the processing efficiency of large items such as air conditioners, refrigerators, and furniture. As of June 30, 2020, JD Logistics operated more than 750 warehouses. Including the cloud warehouse area managed by JD Logistics, the total warehousing area of JD Logistics is approximately 18 million square meters.
5G, artificial intelligence, big data, blockchain... In the current era of rapid technological development, promoting technological innovation is the first driving force for the development of all Internet companies. Especially in this special yearIn a development environment, technology has become the key for Internet companies to break through adversity. JD.com has always attached great importance to technology investment, and technology drive is the core strategy of JD Logistics and an important driving force for JD Group to achieve steady growth in adversity.
Data is boring but also the most convincing. As the first national shopping festival in the post-epidemic era, JD.com’s 618 this year set a new record of 269.2 billion in order volume. Driven by technology, JD Logistics’ open business revenue increased by more than 80% year-on-year. Same-day and next-day delivery of integrated warehouse and distribution orders accounted for more than 91%. Nationwide, 24-hour delivery accounted for more than 90% of districts and counties, maintaining its proportion. The standard is usually even higher.
Relying on technology accumulation and logistics infrastructure, in the past few months, JD Logistics has withstood the pressure and taken multiple measures to maximize the technical capabilities built over more than ten years, while protecting people's livelihood and promoting logistics. Production and stable growth have played a key role.
Enterprises are the main body of the society and economy. When social and economic development faces difficulties, more outstanding companies with the strength and ability to turn the tide need to stand up, stand up, and turn crises into opportunities. From stepping forward during the outbreak to proactively leading the way in the post-epidemic era, JD Logistics’ actions can be regarded as an example.
"New infrastructure" explodes with surging momentum
"In the next twelve years, we will only have three things - technology! Technology! Technology! "This is the end of the key speech at the JD.com Group's annual meeting in early 2017. This year was also a watershed in the development history of JD Logistics. JD Logistics officially transformed from corporate logistics to logistics enterprise, and a large number of practical scenarios made JD Logistics more deeply aware that technology is the first factor leading the development and reform of logistics. Continuous expansion in the technology field has also become the secret to JD Logistics’ outstanding performance during this year’s epidemic and the economic recovery in the post-epidemic era.
As the first national shopping festival in the post-epidemic era, this year’s JD.com 618 has placed too many expectations on it, and JD.com has lived up to expectations and delivered a record-breaking performance. Among them, JD Logistics, which is responsible for the important guarantee task of this nationwide consumption carnival, has also completed phenomenal operations that are even better than usual. Among them, core logistics technology covering all scenarios plays an extremely important role.
As one of the core technologies of new infrastructure, 5G technology has become the focus of competition among major Internet companies. As an explorer at the forefront of logistics technology, JD Logistics has joined hands with the three major operators to explore the implementation of the technology since 5G was officially commercialized. At present, all Asia Ones of JD Logistics have covered 5G networks, and with the support of 5G technology, they can provide consumers with more efficient services.
During this year’s 618 period, JD Logistics’ digital fleet integration has connected and managed nearly 200,000 operating vehicles, as well as more than 150,000 pieces of safety auxiliary management equipment, completing cold chain, large items,Network B, Network C, and TC have hundreds of thousands of transportation tasks, ensuring the safety of logistics transportation and goods. At the same time, the station vehicle dispatching systems launched in Beijing Yayi and Mayong Yayi rely on 5G technology to achieve efficient collaboration of vehicles, bid farewell to traditional manual methods, and realize intelligent vehicle management and in-park dispatch guidance for a total of 20,659 task vehicles. , greatly optimizing the dispatching efficiency of stations and vehicles.
"Black technology" paved the best way to reduce costs and increase efficiency
The continuous research and development of "black technology" has allowed JD Logistics to find the best way to reduce costs and increase efficiency. .
In the second quarter of this year, Asia’s first full-process intelligent flexible production logistics park, JD Logistics Beidou New Warehouse, was completed and put into use in Tianjin. The warehouse has 100% of its expertise in software, hardware and model innovation. Independent intellectual property is a new generation of advanced large-scale automated warehousing production and management system in the e-commerce industry, following the full-process unmanned warehouse, Dilang warehouse, Tiancang and Asia's No. 1 smart warehouse.
JD Logistics has also invested in Asia's first large-scale automatic three-dimensional warehouse in Langfang Yayi. Through automated storage and integrated picking, the efficiency is more than three times higher than that of traditional warehouses. In addition, the intelligent review system launched by JD Logistics can process 45,000 books in a single day; the Internet of Things lighting system realizes intelligent sensing, remote operation, and intelligent equipment connection. On the basis of reducing energy consumption by 90%, the life span can reach more than 10 years. The logistics GIS system supported by AI technology also realizes intelligent order allocation optimization, and intelligent production scheduling improves the accuracy of production capacity control by 20 percentage points, reaching more than 90%.
Since last year, JD Logistics has deeply explored the business scenarios of the Internet of Things blockchain and launched innovative application products such as "Chain Signature" and "Jingyuan Chain".
Among them, Jingyuan Chain has realized the data collection of the whole process information of agricultural products by cooperating with front-end Internet of Things equipment. It relies on Jingdong blockchain technology to establish encrypted traceability QR codes, realizing Jingdong’s fresh products covering farming management. Information traceability and openness and transparency in all aspects of collection and collection. On-chain signature technology not only achieves higher protection of user information, but also uses blockchain electronic documents to replace paper documents, achieving second-level reconciliation, bringing exponential improvements to the operating efficiency of all aspects of the logistics process, creating a seamless Paper-based green logistics.
Build a supply chain technology system to link the whole society
Openness is the development concept that JD Logistics has adhered to since its establishment.
In October last year, JD Logistics established a 5G smart logistics application system with 5G + IoT + artificial intelligence as the underlying core, and exported a series of products such as smart parks, smart digital fleets, smart logistics maps, and value supply chains. and solutions. By this year, more and more partners have enjoyed the technological driving force brought by LoMir, and togetherTongguan 618 promotion.
Taking advantage of the booming development of the industrial Internet, based on its rich experience and technical capabilities in supply chain services, JD Logistics officially proposed at the 2019 Global Smart Logistics Summit held in October last year to join hands with partners Jointly build a supply chain industry platform (OPDS) to promote the industry into an era of high efficiency.
The supply chain industry platform built by JD Logistics mainly focuses on two major directions. One is to provide full supply chain services, and the other is to build a supply chain technology platform. Focusing on full supply chain services, JD Logistics will use "double 24 hours" and "double 48 hours" to open up the entire production and sales chain and double domestic and international connections, especially in the "first mile" to achieve "24-hour delivery from the origin to the country." "Promoting 24-hour delivery to thousands of counties and towns" in the last mile. Focusing on supply chain technology, JD Logistics has created a three-dimensional supply chain technology platform covering three levels: underlying technology, software and hardware systems, and intelligent supply chain. It can be modularized In the future, the digital transformation of China's economy provides broad prospects for JD Logistics to transform the traditional supply chain. JD Logistics will continue to use integrated supply chain services to drive greater openness and build a full-scenario The logistics technology system promotes network sinking and production and sales links, and joins hands with a wider range of partners to jointly promote the logistics industry to be integrated into every aspect of commercial civilization and social life, creating a new era of logistics.
C . Jack Ma talks about what blockchain is, and blockchain is not a bubble. What do you think of the blockchain white paper just released by JD.com?
Blockchain is real, so blockchain is not a bubble. Because it is The technical content is very demanding, so many people don't understand it. Those who can make reasonable use of blockchain technology will create value. Those who cannot use the blockchain itself and blindly use the word "blockchain" as a cover for hype are a bubble.
For example, real estate is a real thing, and the real estate industry is about buying and selling real things, but blind speculation will lead to a big bubble.
D. How to define blockchain What are the application scenarios of blockchain
Many people now believe that blockchain is a universal technology that can do anything, which makes blockchain technology somewhat of a myth!
In terms of the definition of blockchain technology, American scholars In her book "Blockchain: A New Economic Blueprint and Introduction", Melanie Swann defines blockchain technology as an open, transparent, decentralized database.
Blockchain definition: narrow sense VS Generalized
As for the application scenarios of blockchain technology, it is natural to combine the characteristics of blockchain that are different from other technical systems.
Blockchain technology features include:
Blockchain is a database storage system that is distributed around the world and can operate collaboratively. It is different from traditional database operations - read and write permissions are in the hands of a company or a centralized authority (centralized characteristics). 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. As an underlying protocol or technical solution, blockchain can effectively solve the problem of trust and realize the free transfer of value. It has 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 eliminates the need for third-party transfers or brokers.It is an electronic cash system in which both parties to a transaction can directly transfer funds to each other. 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 after transaction" and "instant invoicing"."Reimbursement" - invoicing in seconds and reimbursement in minutes greatly reduces tax collection and management costs and effectively solves problems such as data tampering, over-reporting of one vote, tax evasion, etc. Poverty alleviation is another practical application of blockchain technology. Using blockchain The openness, transparency, traceability, non-tampering and other characteristics of blockchain technology enable the transparent use, precise delivery and efficient management of poverty alleviation funds.
Certificate storage and anti-counterfeiting
Blockchain can be used through Kazakhstan The timestamp proves the existence of a certain file or digital content at a specific time. In addition, its public, non-tamperable, traceable and other characteristics provide a perfect solution for judicial authentication, identity proof, property rights protection, anti-counterfeiting and traceability, etc. In the field of intellectual property , through the digital signature of blockchain technology and on-chain certificates, the rights of text, pictures, audio and video, etc. can be confirmed, and transactions can be executed through the creation of smart contracts, allowing creators to regain control of pricing power, and preserve data in real time to form an evidence chain. At the same time, Covering 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 food and medicine, agricultural products, alcohol, luxury goods and other fields 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, and existing centers Globalized data storage (computing mode) will face huge challenges, and edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the non-tampering and traceability mechanism of blockchain for data ensures the authenticity of the data and high quality, which has become 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 problem of "data monopoly" and "data monopoly". "Island" problem and realize the value of data circulation. In view of 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") Solution. The combination of blockchain and cloud computing will effectively reduce the cost of enterprise blockchain deployment and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also be used in many areas such as charity, insurance, energy, logistics, and the Internet of Things. The field plays an important role.
The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything else. Some people said that this is a new era. With the arrival of blockchain, the past has become classic. Some people say that everything is hype and a bubble after all.
In fact, blockchain technology is not a new technology. The concept has been applied to many industries as early as the past two years, such as electronic signatures. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.
< p>At present, blockchain technology is mainly used in e-Sign Bao products for certificate deposit and certificate issuance. The application scenarios include copyright protection, online signing, web page evidence collection, telephone recording, and mailbox certificate deposit, 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 new application model of computer technologies such as distributed data storage, point-to-point transmission, 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. For unstructured layout files, videos, audio and other large files, the summary information and original files can be saved through the blockchain. Save via a 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 guarantees have certain applications in the field of bidding, solving the problem of capital occupation of bidding deposits for bidding companies. 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, primary business data from multiple trading centers are gathered, and big data analysis technology is combined to build a portrait of a credible bidder. 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 features of blockchain will help solve the above problems., the contract signing between the tenderer and the bidder and subsequent financial service links are all implemented on the blockchain, which not only solves the problem of data credibility but also reduces the entire system's dependence on centralized authoritative institutions.
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 allow enterprises to Able to develop faster and 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.Since blockchain is in line with mankind’s pursuit of freedom and equality, 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.
If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:
Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.
If there are any deficiencies, you are welcome to comment and correct me.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order.And a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.
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.

H. Why do I say that blockchain technology will change the future of social e-commerce
Why do I say that blockchain technology will change the future of social e-commerce?
1. What problems does blockchain technology solve?
“People often ask me recently, everyone knows that blockchain makes money, but can you tell me in one sentence, blockchain What problem does this technology solve?”
Although many people know that blockchain technology supports the operation of Bitcoin, when it comes to what problem it really solves, or what blockchain has created What is the value? Many people in the industry are speechless. Because of the ultra-high money-making effect, everyone cannot calmly look at this industry or even this so-called ecology from an investment or technical perspective.
Recently, when I interviewed some "old people in the currency circle", I got a better answer.
“Blockchain technology is the first time in human history that the problem of trust between people has been solved through technical means.”
Through the characteristics of blockchain, we It can be completely tamper-proof, traceable, transactions through smart contracts, etc. Therefore, in theory, everything that needs to solve the problem of trust between people through technical means will most likely require blockchain technology for development and innovation.
2. The Internet era gave birth to social networking and e-commerce
The Internet is a problem in which humans have greatly optimized information transmission through technical means. In the Internet era, business models are roughly divided into three major modules: advertising, e-commerce, and games. Therefore, in the Internet era, the rise of e-commerce and social networking is beyond doubt.
Taking the current highly competitive e-commerce industry as an example, Alibaba and JD.com are both leaders in the field of e-commerce. The e-commerce industry in mainland China has realized e-commerce in the Internet wave. 17 years of explosive development in the business field. WeChat, the largest social software in China and the second largest in the world, has also become an industry leader.
The current Internet industry has gone through the baptism of time, and an obvious oligarchic effect has been formed after the great waves. Today, every oligarch in the e-commerce market has become an industry heavyweight. Of course, there are also situations where it is difficult for a large ship to turn around. In this state. All e-commerce companies are looking for new directions to break through. And many people are eyeing the social e-commerce field of cross-border cooperation.
The two major representatives of social e-commerce are e-commerce based on the Weibo and WeChat ecosystems. At present, the total market share of social e-commerce has reached as high as 14%-20%
Although many people say that the biggest application of blockchain is currency speculation, SEC and other The launch of the project indicates that blockchain technology has the potential to improve the current status of the industry. It is precisely because there are many teams like the SEC that find the integration point between technology and industry and solve the key problems of the industry, which will be the research direction and consensus of the overall blockchain in the future.
