① SHS uses blockchain to further explore the development of medical insurance
Insurance has high risks, strong dispersion and high sensitivity, which are natural with the attributes of blockchain Fit. The traceability feature of blockchain technology can make the medical insurance service process more transparent; the security capabilities of blockchain can well solve the privacy protection and commercial information security issues in data transmission; and the consensus mechanism of blockchain can The credibility of the transaction is further guaranteed from the source. Due to the above-mentioned characteristics of blockchain, it can largely help the medical insurance industry to realize information sharing and connection of a large number of dispersed nodes within the industry, between industries and between users, thereby greatly accelerating the space and speed of medical insurance innovation.
With blockchain technology, each participant can now individually and digitally load information relevant only to their shared contract. This way, when a transaction is being executed, everyone involved can view the status, history, and process of being authorized. Peer-to-peer (P2P) transmission and open and transparent blockchain technology are becoming very potential value propositions in the industry.
Because blockchain permanently records all transactions between its participants, it is able to provide a level of transparency that current paradigms in the insurance sector do not offer.
SHS (Smart Health Sandbox) selects the SHA-256 encryption mechanism to encrypt the data in the chain. The transaction data and trader information between users are only available to the transaction parties and users with corresponding permissions. Can be viewed. Medical insurance based on blockchain smart contracts will provide a more optimized insurance model. Users do not need to pay expensive insurance management costs, but directly establish intelligent insurance contracts on the blockchain, with management costs close to zero, allowing users to Insurance funds are completely managed and controlled by the user. Medical institutions on the chain can also seamlessly connect with mutual medical insurance, data connectivity, and economic connectivity, allowing people to obtain better medical insurance services.
The third level of blockchain technology development is the process of common development and mutual promotion. Especially for the insurance industry, the application of blockchain technology will greatly improve business efficiency and reduce business risks.
② Bitcherry BCHC proposed "Blockchain 4.0" to promote the application practice of blockchain and e-commerce industry
With the continuous development of blockchain technology, it seems that many industries want to It has something to do with the blockchain, and there is a popular saying in the world: "Those who get the blockchain will win the world." So is this blockchain really as amazing as everyone says? How will blockchain finally be implemented? Today, let’s first talk to you about the application practice of blockchain in the field of “e-commerce”.
First, let’s briefly review what is e-commerce? E-commerce was born in the 1990s. It is a business activity that uses information network technology as a means and commodity exchange as the center and side. We will refer to e-commerce as "EC" for short.”, many people believe that it is the final major commercial use of the Internet, so they call it an epoch-making symbol.
According to data from the US market research company Forrester, by the end of 2018, China’s e-commerce market The scale is expected to reach US$1.1 trillion, becoming the world's first trillion-dollar e-commerce market. The report pointed out that by 2022, the scale of China's e-commerce market will reach US$1.8 trillion, far exceeding the United States and Japan.
With the expansion of e-commerce, it has also greatly promoted the development of logistics, customer service and other industries. But at the same time, it has also brought many problems. According to big data from the e-commerce consumer dispute mediation platform, the number of cases accepted in the first half of 2018 The number of complaint cases increased by 66.93% year-on-year, and the growth rate was much higher than in previous years.
In order to solve the pain points of e-commerce in counterfeit goods, logistics, integrity, supervision, etc., major companies and platforms have also Show your skills and use all your tricks. The most eye-catching one is our protagonist: blockchain. So how does it solve these problems?
First, supervise the production process of goods.< br />
Second, trace and track the transportation of goods.
Third, ensure product sales and after-sales service.
Fourth, provide users with Privacy is protected.
The distributed e-commerce platform Bitcherry BCHC solves the platform trust crisis
Bitcherry BCHC is the world’s first distributed e-commerce platform, which uses blockchain technology Based on it, we are committed to creating a super ecology that covers all aspects of clothing, food, housing and transportation. In the community ecology, all participants, such as users, merchants, super nodes, operating nodes, etc., use the token system for everyone's participation and economic sharing. Open up the online and offline O2O e-commerce system, so that the entire ecosystem can develop healthily, autonomously, and benignly.
It is understood that the distributed e-commerce network has multiple payment methods, distributed sharing mechanisms, and behavioral tokens Incentives, distributed open platforms, multi-industry and multi-community access, global operating nodes, decentralized distributed business organizations, community self-propagation and ripples and other characteristics.
At present, consumption The main pain points of most centralized e-commerce are the leakage of user information, everyone becoming a "digital laborer", reduced merchant profits, increasing customer acquisition costs, lack of supply chain supervision, and repeated product quality problems. Different from traditional e-commerce platforms Centralized model, the underlying technology of the distributed e-commerce platform is a distributed accounting method that allows transaction data, dissemination, purchase, circulation and other behavioral data to be uploaded to the chain, making it open, transparent and non-tamperable. Distribution based on blockchain technology e-commerce, product traceability, logistics supervision, user evaluation and community incentives and other industriesAll questions are well-founded and well-founded. It returns data, traffic and value to the parties involved in the transaction, effectively solving the various shortcomings of centralized platforms.
To promote the implementation of blockchain in actual business scenarios, Bitcherry BCHC proposed "Blockchain 4.0"
According to the reporter's investigation, Bitcherry BCHC will adopt a two-stage implementation of "Blockchain 4.0" 4.0” target. Providing a public chain with high TPS and compatible with Ethereum smart contracts is the first phase of Bitcherry BCHC's measures to ensure the safe and efficient circulation of digital assets in the e-commerce ecosystem. In the second phase, Bitcherry BCHC will provide a large public chain environment that supports the e-commerce ecology - an e-commerce vertical blockchain network platform, allowing e-commerce operators to quickly realize digital operation transformation in the digital economy era and realize mutual cooperation in the e-commerce ecology. diversion. In addition, the reporter learned that the large public chain environment will also provide a governance structure, including a smart contract-based complaint mechanism, reputation scoring, arbitration mechanism, etc., to prevent fraud and damage to the interests of consumers and digital asset investors, and ensure the e-commerce ecosystem compliance and healthy development.
In terms of technology, the Bitcherry BCHC public chain will combine blockchain and DAG technology to provide a chain network system, and the main chain will provide guarantee for the security of the entire system. Use signature algorithms, distributed storage, data operations, consensus mechanisms, message diffusion and other technologies to optimize the distributed e-commerce network architecture, and use a decentralized and non-tamperable structure to allow all participating entities in the Bitcherry BCHC ecosystem to establish a trust mechanism to achieve Second-level fast transaction verification by all parties is the main technical feature of the Bitcherry BCHC project.
③ What is the claims process of the blockchain smart medical sharing platform?
Domestic medical mutual aid and insurance practitioners have already implemented blockchain, and the medical mutual aid platform has been entrusted Help develop the public welfare product "Heart Chain" based on the blockchain. Users' donation amount, fund flow and other information are open and transparent. At the same time, the blockchain is used to realize automatic underwriting and intelligent claims settlement; Zebra Society and Bubi Blockchain cooperate, from a technical perspective to eliminate the possibility of cheating by system organizers; Tongxin Huzhu is based on the Bitcoin blockchain to increase credit for the product.
How to realize automatic underwriting and intelligent claims settlement?
Some medical mutual aid practitioners are using blockchain technology to solve two thorny industry problems: one is to ensure the authenticity of claims information, and the other is to improve the efficiency of insurance claims.
Medical mutual aid uses a lower threshold to solve the problem of serious medical expenses. The specific method is: economic mutual assistance and risk sharing among participants. For example, users pay to become members of the medical mutual aid platform. After the observation period, , if users fall ill, they can receive medical subsidies based on the specific condition. After case publicity, third-party agency investigation and other steps, the subsidies will beThe maximum amount reaches 300,000. After calculation, on the mutual aid platform, the annual cost for an average user is 60-90 yuan.
In foreign countries, mutual aid insurance has appeared very early. Some people with common requirements and facing the same risks organize voluntarily and pay in advance risk loss compensation sharing, usually for major diseases. This kind of mutual insurance can be customized according to the needs of the group. The cost is much lower than the critical illness insurance of several well-known insurance companies, and it is easy to purchase.
The difference between medical mutual aid and insurance is that every member is fully involved, and everyone cares about every move of everyone in the mutual aid group, including who is sick, who needs compensation, and when the money will arrive. Accounting and other issues require the platform to have sufficient self-certification.
Medical mutual aid platforms need to settle claims in accordance with the rules. Whether the user’s diagnosis time is within the observation period can be self-certified using blockchain technology.
Traditional insurance claims involve human factors. For example, in the underwriting process, humans ultimately do the investigation, judgment, and reporting. At the same time, insurance claims take time, and it is often difficult for users to obtain insurance money as soon as possible. In the field of mutual aid, blockchain technology can ensure the accuracy of information. Once the user's information is stored in the blockchain system, no one can modify the information.
“In the past few years, we have been doing medical mutual aid and have accumulated more than 8 million users. There are more and more participants in mutual aid, and the amounts involved are getting larger and larger. We have implemented blockchain applications, and gradually It is found that blockchain has greater value and can realize an automatic machine medical mutual aid guarantee system. From applying for mutual aid to obtaining mutual aid, everything can be realized through artificial intelligence, and the entire process can be compressed to instant compensation. This is financial AI development direction." Zhongtuobang CTO Yu Jianan told Wall Street Insights.
The self-certification function of blockchain can be traced back to a few years ago. In foreign countries, some geeks appended some information to every Bitcoin transaction.
“At the end of this transaction, you can attach the hash value of a picture and a record after performing algorithmic operations on the picture. If you modify the picture, this record will change. We can use this method to complete self-certification. On the platform, each mutual aid voucher contains the user’s own identity information, as well as the time of joining the plan, and other key elements
④ Charity charity on Alipay and WeChat Is donation reliable?
For example, Zijun, a 2-year-old hearing-impaired boy from Jiangxi, is a beneficiary of Internet charity. At the end of 2019, Zijun suddenly suffered from large vestibular aqueduct syndrome and lost his normal hearing. Zijun Jun's brother was diagnosed with first-level hearing disability since he was a child. He worked twice as hard as ordinary people and studied hard to get into a college. But Zijun was suddenly diagnosed with hearing impairment, and cochlear implant surgery required 200,000 yuan. By chance, Zijun’s mother came into contact with the public welfare project launched by the China Siyuan Engineering Poverty Alleviation Foundation on Alipay.Title "Decibel of Love". In May 2020, with the donations from thousands of caring netizens whom she had never met before, Zijun completed cochlear surgery. So far, caring netizens have donated more than 18 million times to "Decibel of Love" on Alipay, raising more than 42 million yuan in charity. Since 2016, these donations have funded more than 630 hearing-impaired children to improve their hearing aids or implant cochlear implants, helping them bid farewell to the silent world and regain a "new voice."

(5) Extended reading on blood donation based on blockchain:
Blockchain is far more than just a technology, it involves The spirit of "multi-party collaboration". In modern society, many things must rely on everyone's cooperation to achieve the effect of 1+1>2, but in cooperation, we need to try our best to avoid problems such as "information asymmetry."
Therefore, alliance members jointly keep accounts, share data, and make everything public to eliminate "information asymmetry" to protect everyone's interests and allow the business environment to develop healthily. If you do things honestly, you will get the benefits you deserve. If you cheat, it will be known to everyone and criticized by thousands of people. Technology is the foundation that helps realize this model. This is the more important "blockchain thinking".
⑥ What kind of technology is "blockchain"?
What kind of technology is "blockchain" Blockchain is an important concept of Bitcoin. The "2014-2016 Global Bitcoin Development Research Report" released by the Internet Finance Laboratory of Tsinghua University PBC School of Finance and Sina Technology mentioned that blockchain is the underlying technology and infrastructure of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Account book. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes automated Smart contracts are composed of scripts that program and compute data in a new decentralized infrastructure and normalize computing.
Domestic blockchain application platforms include an asset custody system based on blockchain technology jointly developed by the digital currency crowdfunding platform Biying China, China Post and IBM.
Blockchain is a decentralized, distributed ledger system participated by nodes. The data stored on it cannot be forged or tampered with, and is open to the public. Transparent, the information and value recorded by each account at any point in history can be found on the blockchain. The characteristics of the blockchain protocol are smart contractsExecution provides the necessary foundation, and contracts can be automatically executed and trusted according to established conditions without the need for auditing by any centralized organization.
Blockchain technology is the underlying core of the Bitcoin system. Its essence is a decentralized ledger. When people conduct transactions through the Internet, a new transaction will be recorded on the ledger, and this ledger is A decentralized ledger is jointly maintained by everyone on the network. People can see ongoing transactions at the same time, and control is not in the hands of institutions or individuals. Transactions cannot be tampered with or forged, and they will be permanently stored in the ledger.
For example, the Tongxin Huzhu blockchain mutual aid platform has four major characteristics in applying blockchain technology:
Openness and transparency
Openness and transparency, once all information recorded on the blockchain is recorded, it will be very It is difficult to tamper with and cannot be hidden, and users can check it at any time.
Democratic decision-making
Bottom-up decision-making, the blockchain proposes a variety of different consensus mechanisms to help users effectively form bottom-up decisions and jointly participate in major decisions.
Accurate execution of rules
Accurate execution of rules. The smart contract technology defined on the blockchain converts all rules into public and clear codes, which can be executed accurately and accurately. Once anyone is identified Cannot intervene.
Never downtime
Never downtime, the blockchain based on the public chain is not affected by any organization or individual. As long as the incentive mechanism is effective and the Internet exists, the blockchain will exist.
What is blockchain? Blockchain is a decentralized shared accounting technology that allows all parties involved to establish a trusting relationship at the technical level. Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain. Blockchain is still in its infancy. Many people have discussed with me how we can ensure both rights and privacy at the same time. Of course, we are just exploring now. We need fair content across the entire network and clear protection. This is what I can only say. So far, this is my arrangement for the future.
Blockchain concept? The idea of blockchain is to be completely decentralized and rely on decentralized justice. In that case, theoretically the cost will drop a lot, proving that real assets and property rights can directly correspond to each other on the Internet. It has solved the problems of decentralization and asset ownership that were not solved by the first generation of Internet information. How big a role does big data play in financial innovation now? Only by registering big data can we know who it belongs to. In fact, this has always been a problem that we cannot solve now. This is not a small problem. If there is a technology in the capital market that makes the property rights of things that were originally unclear clear, that will be a big problem for us. The entire market is undergoing a huge transformation.
What is blockchain? Blockchain technology itself can solve data ownership, pricing and sharing issues.system. This still cannot completely solve certain problems. To give a simple example when it comes to user privacy, I have a piece of data placed on the machine. The partner comes over and makes an insurance analysis to analyze the cooperation. There is a risk here. Or not, can we deal with it or clarify the property rights of the laboratory, and then clarify the processing rights and data rights. The common products produced by everyone are common to everyone. If we need to divide different things, how to price them and how to divide them? In addition to the technology of blockchain and a decentralized database, when it comes to the above mentioned tasks, it is another issue, and then there is the issue of pricing and the market mechanism. All fields have proven to recognize this rule, so this I think blockchain is a very good core technology, but it cannot cover all problems.
Introduction to Bubi Blockchain
Bubi Blockchain is mainly positioned to provide commercial-grade blockchain infrastructure services, which mainly includes building a blockchain system and building on top of the blockchain system. A support system with high expandability. On top of this support system are applications from all walks of life. Bubi focuses more on the underlying technology of the blockchain. In the past three years or so, a team of more than a dozen people has devoted almost all their energy to the research and development of the underlying technology. The reason why Bubi Blockchain chooses points has something to do with the market's promotion method. As we all know, blockchain is a technology that is very suitable for the issuance and trading of digital assets. Points are a digital asset that is naturally legal and compliant, and has a small impact because of its small amount. Therefore, it is a very suitable choice to use points as your first attempt at digital asset issuance. Issuing points based on the blockchain can indeed bring great help to the circulation and mutual exchange of points.
What is blockchain? The application of blockchain technology in the field of property transfer is only one aspect. In addition to reducing property transfer costs, blockchain technology can also be applied to various fields involving company stocks, financial derivatives, and points programs of commercial institutions. The blockchain community is currently focusing on promoting the wider application of this technology in the field of financial assets. Relatedly, various platforms that are still under development have also received very considerable investment.
Blockchain concept? Structurally or by definition, these things are very different. The U.S. dollar, or any currency, from a typical definition, is primarily used as a medium of exchange or store of value for economic activities. Within the geographical scope where a certain currency circulates, people in the region reach a consensus on the use of this currency, making it convenient for everyone to use the same currency to purchase goods or services (the function of currency as a medium of exchange). There is a responsibility to manage the currency through monetary policy in order to ensure the preservation of the value of the currency and avoid the occurrence of inflation (the store of value function of currency). In today's world, almost everyone uses some form of currency in their daily lives.
What is blockchain? Even developers within the blockchain community often easily overlook the big picture mentioned above. There are many competitive projects in the blockchain community, and they are also full of variousA controversy about the evolution direction of blockchain technology. Over time, some projects in the community will be successful, and others will not be so lucky. Things will not always develop in the direction we expect, but no matter how these projects in the early blockchain community develop, one thing is very clear, that is, blockchain technology has brought us at least A revolutionary function: Blockchain technology will greatly reduce the cost of financial property transfer, and blockchain will be used to control, manage and transmit financial property.
What is blockchain? Blockchain concept? After a certain application analysis, we return to the starting point. The definition of this blockchain technology will surely become more and more abundant with the expansion of applications, and people will discover more mysteries of blockchain technology.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the basis for Bitcoin. underlying technology. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet information. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. The lightweight Bitcoin wallet uses online confirmation, which means it does not download the blockchain data to the device storage.
Many of Bitcoin’s altcoins also use the same design, but are slightly different in proof of work and algorithm. For example, using proof of stake and SCrypt, etc.
Blockchain timestamp service and proof of existence
This concept was proposed in Satoshi Nakamoto’s white paper [1], who created the first block, the “genesis block”.
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left an unchangeable sentence in the genesis block:
“The Times 03/Jan/2009 Chancellor on brink of second lout for banks (on January 3, 2009, the chancellor was on the verge of implementing a second round of bank bailout)."
It was then that the British chancellor Darling was forced to consider a second bailout of the banks. In a time of crisis, this sentence was the headline of a front-page article in The Times that day.
With the blockchain’s timestamp service and proof of existence, the time when the first blockchain was created and the events that were happening at that time are permanently retained.
The Bitcoin company BTCC launched a service "Millennium Chain" in 2015, which is a blockchain engraving service, which uses the above principles. Users can engrave text on the blockchain through this service, stored permanently.
Bitcoin, Litecoin, Ruitai Coin, and Qianjin Card are all digital currencies based on blockchain technology.
Chongqing Jinwowo analyzed: Blockchain is actually a decentralized distributed ledger database.
How popular is blockchain technology?
Blockchain technology makes DAC possible. DAC is something that can fundamentally subvert the organizational model of human society. I believe that its impact on society will surpass the Industrial Revolution and become the most profound change that the Internet has brought to the world.
The essence of blockchain technology is a method of data storage, transmission and certification that is decentralized and contained in a distributed structure. It replaces the current Internet with data blocks (Block). The road's reliance on the central server enables all data changes or transaction projects to be recorded on a cloud system, theoretically achieving self-certification of data during data transmission.
Blockchain technology can be applied to many industries:
Art industry
Ascribe allows artists to use blockchain technology to declare ownership, Issue numberable, 100% editions of your work in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
Legal Industry
BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property rights. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.
Development Industry
Colu is the first company to allow other companies to issue digital assets. They can "tokenize" various assets and have a profound impact on many people. Although the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu tokens can be configured in various states and types, and can leave and return to the system. , and when storing data on the blockchain is too large, the data can be stored on the BitTorrent network.
Internet Mutual Aid Industry
Tongxin Mutual Aid is the first blockchain online mutual aid platform to be implemented and applied. Technically, through blockchain and big data technology, it eliminates the shortcomings of the traditional online mutual aid model. Establish an open and transparent new online mutual aid platform.
Aite Cat is a virtual pet game produced under blockchain technology. This virtual cat is similar to an online Leitz dog. , 360’s pet cats, and NetEase’s Planet are all the same type of blockchain virtual products. The difference between Aite Cat is that the entire cat design adopts a 3D three-dimensional effect, so that the cat display is no longer The singleness of the picture makes the cat movable and increases the fun of the cat.
What technology is the Huangbao blockchain system?The Huangbao blockchain is a powerful decentralized loop intelligence system. The Huangchain chain is referred to as HUANG. It is the first to be used in financial services, advertising media, games and entertainment, various life applications and other fields, becoming a blockchain 3.0 The representative virtual currency of the era, Media Chain 3.0 technology has the core characteristics of being safer, more efficient, more flexible, and more open. The widespread application of its technology will surely trigger new forms and new ideas in the global media industry, which can Create convenient services and new concepts, which marks a new economic era before the public.
⑦ Re-understand the blockchain: Enlightenments brought by more than 1,550 application cases
Author: Ran Wei
(This article is excerpted from "2021 Global Area Blockchain Application Market Report")
When we talk about blockchain, anyone who knows something about blockchain can more or less express some of their own opinions on related topics. . For example: from the perspective of technical system, blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm; from the perspective of functional attributes, blockchain is decentralized, non-tamperable, and full-process. Features such as leaving traces, traceability, collective maintenance, openness and transparency.
Looking back at the history of blockchain, there is no way around Bitcoin. On January 3, 2009, the Bitcoin genesis block with serial number 0 was born. A few days later, on January 9, 2009, Bitcoin block number 1 was born. When two blocks are connected, the blockchain is "born."
The inventor of Bitcoin, whose pseudonym is “Satoshi Nakamoto”, may find it difficult to imagine: In the past 12 years, with Bitcoin as the center, a huge “cryptocurrency family” has spread all over the world. The financial market set off a "big wave" that continues to this day. During this period, innovation and risks related to cryptocurrency are intertwined, progress and bubbles coexist, and pursuit and criticism coexist, and it drives government departments of various countries to continuously improve the monetary and financial systems, social governance and supervision systems.
At the same time, the blockchain that accompanies Bitcoin is also evolving rapidly, and has long gone beyond the scope of "Bitcoin's underlying technology" and has been applied to every corner of social and economic development.
So, what mechanism does the blockchain work through? Compared with traditional technologies and models,What are the advantages of this method and what is its application effect? In the "2021 Global Blockchain Application Market Report" jointly released by Capital Lab and Yuanwang Think Tank, we tried to provide a certain basis for the above issues through research on more than 1,550 application cases around the world in 2020 and the first quarter of 2021. Empirical answer. At the same time, based on the study of these cases, we can establish a new understanding of blockchain: blockchain is trust, blockchain is sharing, blockchain is transaction, blockchain is substitution, and blockchain is efficiency.
In the Bitcoin creation paper "Bitcoin: A Peer-to-Peer Electronic Currency System", "Satoshi Nakamoto" repeatedly emphasized that Bitcoin has the characteristics of not relying on a "trusted third party". That is the characteristic of “decentralization”.
On the other hand, the underlying technology of Bitcoin, the blockchain, is precisely designed for "trust." In other words, reshaping "trust" in the digital age is the most basic function of the blockchain, but this trust has been transformed from trust between people and legal entities to trust between machines and machines. Trust between blocks and between nodes. Interestingly, the subsequent “smart contract” function has further strengthened this trust through its integration with the blockchain.
Identity coding and authentication are the first steps to achieve the above-mentioned trust mechanism, and the distributed identity (Decentralized Identity, DID) system is the core of it. With DID applications, everyone from individuals to organizations to IoT devices, from physical items to virtual products, can be given digital "identities" and achieve trusted interactions. It is precisely because of this that blockchain-based certificate storage, empowerment, verification, circulation, and transactions can be realized, and only then can blockchain be implemented in various industries.
Application cases from around the world show that new trust mechanisms provide new rules and motivation for social and economic operations:
l China is comprehensively promoting blockchain electronic certificates Applications such as "one fish, one code", "one fruit, one code", "one tea, one code" and other applications are driving the global Anti-counterfeiting traceability of agricultural products and upgrading of food safety systems;
l Through the combination of blockchain, big data, and artificial intelligence, the credit "portrait" of an enterprise is more accurate and can be obtained faster and more accurately. Lower-cost financing services;
l Charitable charity organizations have put charity funds "on the chain" to form a more transparent and standardized charity tracking and management system;
l Relevant cities in China have launched a blockchain-based gas cylinder product traceability management system, and the credibility of the source of gas cylinder file information and the level of gas cylinder safety management have been greatly improved;
l Germany isEstablish a digital registration system based on identity authentication for its distributed energy assets to promote the development and trading of renewable energy and cope with the arrival of the digital energy era...
Among the three types of blockchains (public chain, alliance chain, private chain), alliance chain has been the most widely used. In addition to considerations of technical performance, operational efficiency, operability, expected results, etc., this is mainly because all parties in the alliance already have a certain foundation of trust. This also shows from another perspective that in blockchain applications beyond cryptocurrencies such as Bitcoin, "multi-centralization" rather than complete "decentralization" is a more realistic option.
In addition, it is undeniable that unlike the proof-of-work mechanism that Bitcoin “mining” relies on, the blockchain cannot completely ensure the integrity of the on-chain data from the source in the actual application process. Authenticity. In other words, a certain alliance member or node may provide false data intentionally or unintentionally. However, with the help of blockchain's non-tampering, traceability, multi-party consensus and other characteristics, the alliance can identify counterfeiting behavior and impose corresponding punishments, such as "kicking" the counterfeiting members from the node. Therefore, in a sense, blockchain-based trust largely establishes alliance members’ awe for the authenticity of data and deters data fraud.
If "trust" is the foundation of blockchain applications, data sharing is the core of blockchain applications. Without data sharing, there will be no cooperation, and the practical application of blockchain will be impossible.

Although the above application cases in finance, government affairs and various industries are only a few typical cases, they are enough to illustrate that: on the one hand, data sharing is an inherent requirement of blockchain applications. In terms of specific implementation, everything must start from breaking "data islands" and "information asymmetry"; on the other hand, the application practice of blockchain has in turn promoted cross-level, cross-department, cross-industry, cross-region, and cross- Data sharing and unprecedented cooperation across national borders.
It can also be seen from the above cases that based on the transparency, security, trustworthiness and other characteristics of the blockchain, data sharing allows cooperation that originally seemed impossible to be achieved, and more Open innovation results; data sharing can effectively improve the operating efficiency of business systems, financial systems and social governance systems; various organizations promote their own organizational changes and process changes while sharing and cooperating with external institutions.
Based on trust and sharing, "transaction" is the most intuitive and deepest manifestation of the value of blockchain applications. Currently, blockchain is opening a new chapter in the transformation of transaction models in various industries around the world.
From the perspective of functional architecture, blockchain-based transactions are by no means just a change in the transaction process. Instead, they integrate various unique functions of the blockchain. Integrated integration of blockchain applications such as logistics, payment/settlement, supply chain financing, insurance, and network security.
From the perspective of application form, blockchain-based transactions transcend the traditional concept of product or service transactions and represent the realization of the value of a wider range of data in circulation.
From the perspective of application scenarios, transactions based on blockchain involve the upgrading of the physical industry, the digital advancement of the financial industry, and the innovative application of the "token economy".
In the physical industry, take the application of agricultural blockchain as an example: on the one hand, supply chain traceability based on blockchain has become an important barrier to food safety; but on the other hand, for growers or For farmers, the supply chain traceability function is far from enough. how to help themExpanding the sales of agricultural products and obtaining as much income as possible is the "hard truth" for blockchain technology to continue to promote agricultural development. In other industries, the same applies.
Against the above background, new trading platforms in the global physical industry continue to emerge:
l The Indian government uses blockchain platforms to help farmers in remote areas sell agricultural products to reduce the While eliminating intermediate fees, obtain higher income;
l The Swiss company Cerealia builds a blockchain-based agricultural product trading and financing platform to promote the export of agricultural products in emerging market countries around the world;
l The world's largest independent refined sugar producer, Al Khaleej Sugar Company of the United Arab Emirates, launched DigitalSugar.io, a blockchain-based sugar product trading platform, to realize spot-based international raw sugar trading;

l Honeywell launched GoDirect Trade, an online trading platform for new and second-hand aircraft parts, providing a valuable reference for large manufacturers on how to apply blockchain to parts trading and circulation... ….
In the financial industry, blockchain is promoting the digital advancement of financial transaction business in aspects such as securities trading, asset securitization, trade financing, and cross-border settlement:
l The Australian National Stock Exchange has launched ClearPay, a digital securities trading platform based on distributed ledger technology, which can provide multi-currency, real-time DVP settlement on the same day and will replace the original exchange settlement system;
l Switzerland The company Finka has launched a related securitization token investment platform based on livestock from organic pastures in Bolivia to promote the development of the local livestock industry;

l Nanjing Iron and Steel completed blockchain-based iron ore transactions with Rio Tinto of Australia and Vale of Brazil respectively;
l Baosteel Co., Ltd. and Australia's Rio Tinto completed the first blockchain-based RMB cross-border settlement transaction...
Of course, while blockchain promotes the advancement of financial transaction business, dark sides such as hype, scams, money laundering, and cyber attacks related to blockchain and cryptocurrency continue to follow. How to continue to promote financial innovation while also carrying out efficient risk prevention and control and effectively cracking down on illegal crimes is an important issue that requires long-term response. From a global perspective, China has responded with clear attitudes, strict measures, and effective measures in this regard.
The transaction changes realized by the blockchain in the real industry and financial industry are only the initial stage of the blockchain changing the traditional transaction method. The "Token Economy" is the blockchain "transaction" A higher level of functionality.
Under the framework of the "token economy", from electronic certificates to skill certificates, from credit records to public welfare activity participation records, from social media tracks to carbon emission reduction actions, when various data become When an encrypted digital proof of rights is circulated and exchangeable, it is given the function of "token".
Regardless of the investment/speculation craze of "Non-Fungible Token (NFT)", we can already see many early applications of "token economy" around the world:
l The HotCity project supported by the Austrian government uses a crowdsourcing model combined with blockchain and gamification tokens to encourage residents to submit heating waste heat hotspots to meet urban heating needs more efficiently;< br />
l Ford establishes "Green Miles" for commercial and municipal fleets using hybrid vehicles to help improve urban air quality;
l Weibin District, Xinxiang City, Henan Province, in its In the blockchain industrial park project, tokens are issued based on the points system for merchants and enterprises to establish a new commercial service platform;
l Chengdu released a blockchain-based community governance product "Chain Community", Residents can earn "time bank" points on the platform through volunteer services and other activities, and exchange them for benefits and discounts provided by community merchants;
l Global non-profit organization "Mobile Open Blockchain Plan" The Electric Vehicle Charging Network Working Group (EVGI) launches a global standard system for decentralized vehicle charging technology, covering the Tokenized Carbon Credit (TCC) scenario;
l Blockchain reward platform MiL. k and Korean retailersCooperate to provide its members with blockchain-based points management services. Members can convert existing points into local MLK tokens through the MiL.k platform, or exchange them into other third-party points...
As can be seen from the above cases and more, the "token economy" has several distinctive features:
The "token economy" gives assets to a wider range of data Attributes and tradable attributes, and through cross-domain and cross-platform mutual trust and circulation, can improve the operating efficiency of the entire social and economic system;
"Token economy" is a new value creation and The realization process does not necessarily use currency directly as the medium of exchange, but is more reflected in the exchange, mutual benefit and reallocation of various elements and resources;
"Token economy" is often combined with incentive mechanisms. At the same time, through incentives for "good people and good deeds", "good companies" and "good institutions", the social value system and social credit system will be effectively reshaped.
Generally speaking, the "token economy" will spawn new production factors, reshape production relations, and greatly liberate social productivity; the "token economy" represents the direction of the "information Internet" The evolution of the "Internet of Value" indicates the most exciting future of the digital economy; the "token economy" based on the blockchain has begun to take shape and has begun to bring changes to economic operations, social governance, and everyone's lifestyle. Continuously visible change. All types of institutions and individuals should be mentally and physically prepared for this change.
Like other new technologies, in the process of application and popularization, blockchain continues to produce substitution effects in terms of platforms, media, models, methods, etc.: physical documents are replaced by electronic documents, and credit records are replaced by electronic documents. Tokens are replaced, manual review is replaced by data verification, and the city management platform is replaced by the "city brain"...
Such substitutions have become the norm:
l Argentina’s central bank has begun a proof-of-concept for a new blockchain clearing system, which may replace the existing clearing system;< br />
l Korea Minting and Security Printing Corporation (KOMSCO) expanded its blockchain digital gift certificate business to replace paper gift certificates and achieved record revenue despite a sharp decline in the issuance of banknotes and coins. Improvement;
l Courts across China have begun to use blockchain electronic seals to replace traditional paper seals in the enforcement of real estate seizures;
l The Shanghai court system is using artificial intelligence , the adoption of new technologies such as blockchain, and explore the use of digital court trial records to replace manual court trial transcripts;
l The Japanese company SUSMED launched a "Clinical Data Monitoring System Demonstration Using Blockchain Technology" pilot, indicating that the drug or clinical trials of medical devicesThe necessary monitoring process during the inspection can be replaced by a blockchain system;
l Alipay and Wukong Car Rental have cooperated to launch a "face-swiping" car rental service. Through blockchain technology and a credit-free model, tourists only need to You can rent a car by "swiping your face" and return the vehicle through mobile phone operations;
l Under the new crown epidemic, local governments in China have intensively launched "non-face-to-face, no-contact, The "zero legwork" government service has replaced the traditional offline service method and provided a strong guarantee for the smooth progress of remote bidding, "cloud" customs clearance, financial support, resumption of work and production, etc. during the epidemic...
In addition, we can also see that through the use of blockchain technology, various enterprise-level services are also realizing substitution and evolution: from paper contracts to electronic contracts, to program-based, Blockchain contracts that can automatically execute smart contracts. Blockchain is pushing contract signing into the era of "chain signing"; from offline human resources companies to online human resources platforms to the blockchain-based human resources market , global human resources services have experienced continuous changes from the 1.0 era to the 2.0 era, and then to the 3.0 era.
Generally speaking, when the blockchain "invades" various industries, it will "mercilessly" delete all unnecessary links and processes, all unnecessary manual operations, and accelerate the The era of paperless, unmanned and automated is coming.
In the process of our analysis of more than 1,550 blockchain application cases around the world, words like "improve", "accelerate", "shorten", "lower", "reduce", "save", " Words such as "save" appear frequently in front of our eyes. These words show that the improvement of efficiency is the common pursuit of all parties involved in blockchain applications and is also the most direct result of the substitution effect of blockchain.
Numerous application practices are contributing to this:
l Kenyan company Shamba Records provides blockchain traceability, transaction and financing services to farmers in the country, currently covering more than 6,000 Small farmers and helped them increase their income by at least 40%;
l TradeWaltz, a blockchain trading platform invested by NTT DATA, Mitsubishi and other companies, completed a trial run, and the results showed that the platform can reduce traditional 50% of the workload of the trade process;

l Taizhou, Zhejiang uses "Internet of Things+" The "blockchain" recycling system solves the problem of marine pollution control. Compared with traditional processing methods, this recycling system can save 94% of labor costs and 84% of operating costs...
In summary, through the joint action of trust mechanism, sharing mechanism and transaction mechanism, blockchain has formed an obvious substitution effect, improved the operational efficiency of finance, government affairs and various industries, and will Continue to create systemic change. This change is reshaping the relationship between people and machines, people and society, and people and the environment, and clearly points to three ultimate goals: efficiency, well-being, and environmental protection.
⑧ In addition to donations, what else can blockchain charity do?
In the face of the urgent shortage of resources, major Internet companies have taken various actions to actively rescue areas with severe epidemics such as Wuhan. In this rescue operation, we also saw that some blockchain companies are also taking active actions. Incomplete statistics show that as of now, blockchain traders include Ant Financial, Du Xiaoman Finance, Qulian Technology, Huobi, Ouke Group, Zhen Fund, Quantum Chain Foundation and other blockchain-related companies. Donation: Du Xiaoman Financial On January 27, Du Xiaoman Financial announced on Weibo that it would invest 10 million yuan in cash to the Internet Epidemic Special Fund to fully support the series of efforts to fight the epidemic.

All medical staff in institutions participating in the fight against the epidemic can receive it. After successful receipt, during the epidemic period announced by the National Health and Medical Commission, if medical staff are unfortunately infected while fighting the epidemic, they can apply for a 100,000 yuan security fund after diagnosis; if they unfortunately die due to illness, they can apply for a 500,000 yuan security fund. Medical staff search for "Ant Insurance" blockchain traders on the Alipay APP homepage and enter the page to claim it. The function of claiming on behalf of family members and colleagues is currently under development.
Qulian Technology According to the Qulian Technology official account, after the Wuhan New Pneumonia Prevention and Control Headquarters issued an announcement on accepting social donations on January 25, Qulian Technology donated 100,000 N95 medical masks. Sent to 10 hospitals including Wuhan Youfu Hospital, Wuhan Xinzhou District Traditional Chinese Medicine Hospital, and Central Theater Command General Hospital (Wuchang Park).

According to Krypton Capital, Maggie Wu of Krypton Capital launched the “Blockchain Charity Organization” blockchain trader. Currently, more than 50 people have participated. It has raised 45,000 USDT (approximately 300,000 RMB) in charity donations and donated funds to the world. Purchase medical supplies from various places. Besides donating, what else can blockchain companies do? During this epidemic, from the initial issue of information disclosure to the transparency of the entire donation process, the "trust machine" of blockchain can actually be used. The transparency, non-tamperability, anonymity, traceability and other characteristics of blockchain are naturally suitable for the charity industry. Now, many charitable organizations have tried to join forces with enterprises. Ant Financial Charity uses blockchain technology to track fundraising, establishes a third-party publicity system, and provides blockchain fund flow disclosures to provide data statistics for public welfare organizations., provide convenience for project execution tracking; Beautiful China teamed up with JD Charity to realize material donation to schools in remote mountainous areas based on blockchain; Tencent Charity Search used the multi-node deployment of the alliance chain to deploy blockchain traders, linking WeChat, 404 family search, Systems such as Baby Come Home realize information exchange. This epidemic originated from some people eating wild animals. After this epidemic, people should pay enough attention to food safety. The fundamental reason for the frequent occurrence of food safety incidents lies in the opacity and asymmetry of information between the government, enterprises, sellers and final consumers. At the same time, different accounting methods are used in planting, production, transportation, storage, sales and other links, resulting in very poor food traceability. Blockchain technology promotes the further improvement of the food safety traceability system. Through the tamper-proof distributed ledger technology combined with the Internet of Things and other technologies, the entire process of food can be traced from source information collection and recording, production and processing, warehousing and logistics. At the same time, blockchain technology brings third-party regulators and consumers into the regulatory system, breaking information islands and achieving process transparency to a certain extent.
At present, Internet companies such as JD.com, Suning, Internet, and Alibaba have begun to deploy blockchain traceability systems, and some startups are also targeting the blockchain traceability market. If we establish a complete food traceability system, people can easily check the source when buying food, which may prevent such incidents from happening again to a certain extent. However, all technologies are not omnipotent, and preventive behaviors are ultimately implemented by people. Special reminder: The number of cases of pneumonia caused by the new coronavirus continues to increase. Readers and friends should try to avoid gatherings during the Spring Festival, wash hands frequently, wear masks in public places, drink more water and rest
