㈠ What do we need to know to learn blockchain
First we need to understand the relevant content of network communication, followed by data storage, encryption technology, consensus mechanism and security technology, and finally It is cross-chain technology and off-chain technology. I personally think that learning about blockchain should start from practice. If you are a programmer, you can go to a blockchain-related company to get in touch with related businesses and learn on the job. I used to work at Xuanling Technology, and the company’s strength and experience in blockchain development are very good, making it a good candidate for both work and cooperation.
㈡ 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 blockchain work through? What are its advantages compared to traditional technologies and models? 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", and also It 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 is developing its distributed energy resources Assets establishes a digital registration system based on identity authentication 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: in surpassing BitcoinIn blockchain applications such as cryptocurrency, "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.
l The State Administration of Foreign Exchange's "Cross-border Financial Blockchain Service Platform" pilot has been fully launched, promoting foreign trade exports through information exchange between foreign exchange bureaus, taxation, banks and enterprise-related market entities. Business development;
l The "Insurance/Claims Alliance Chain" jointly established by 11 insurance companies in Taiwan has been put into operation, and each company has achieved "single application and common documents" on this platform;
l Blockchain platforms such as Contour and TradeLens are reshaping the global supply chain and providing impetus for the digital transformation of international trade through data collaboration among enterprises, financial institutions, shipping companies, terminals, customs and other institutions... .
l In China, through data collaboration, various government departments have realized "one data, one source, one source for multiple uses, one network, and full network operation";
l Through The "Judicial Chain" platform allows all types of electronic evidence to be seamlessly connected with judicial institutions such as notarization, arbitration, judicial appraisal, and courts, which improves the efficiency of the judicial system while reducing costs;
l Targeting grassroots nationwide The court's "cross-domain collaboration mechanism for trial auxiliary matters" can realize "cross-domain service and cross-domain evidence collection" between courts in different regions, effectively improving the efficiency of trial auxiliary matters and trial quality and efficiency, and reducing judicial operation costs... ….
l China's "Guangdong-Hong Kong-Macao Greater Bay Area Combination Port" project was officially launched, which can support the interconnection and interoperability of trade parties among the five major customs jurisdictions of the Greater Bay Area and become the first connected port in the Greater Bay Area , customs, logistics, enterprise, finance and other trade processes, interconnected and shared blockchain network;
l Japan's KDDI Telecom, Hitachi, Kansai Electric Power, Sekisui Construction and other large enterprises have established blocks Chain Alliance NEXCHAIN to form cross-industry real estateproduction information sharing and management model, and promote cross-industry innovation;
l The French Renault Group completed the test of its blockchain project "XCEED" for use between parts suppliers and automobile manufacturers Share compliance information and streamline compliance certification….
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 them expand the sales of agricultural products and obtain more income as much 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 Get higher income while reducing intermediate costs;
l SwitzerlandThe company Cerealia builds a blockchain-based agricultural product trade 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, the UAE Al Khaleej Sugar Company, launched a blockchain-based agricultural product export DigitalSugar.io, a blockchain-based sugar product trading platform, realizes spot-based international raw sugar trading;
l Jiangxi Ganzhou launched a blockchain-based international timber electronic trading platform to conduct the entire process of timber trading On-chain management, and will provide full industry chain services such as cloud warehouse supervision, logistics, finance, and insurance for the timber market;
l Shandong Province has launched the Shandong Internet Chinese Medicinal Materials Trading Platform, which will use blockchain, etc. Technology realizes online integrated services of quality control, trading, payment, settlement and supervision;
l Weitang Town, Xiangcheng District, Suzhou released a blockchain-based pearl online trading platform, which analyzes the core parameters of pearls and Test reports will be uploaded to the chain for certificate storage, and functions such as supply chain management, trade finance, smart contracts, payment settlement, and incentive mechanisms will also be added;
l Honeywell launches new and second-hand aircraft parts GoDirect Trade, an online parts trading platform, provides 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 The American company Securitize has established a Japanese real estate investment platform based on digital securities , aiming to revitalize idle real estate in rural Japan and enhance the vitality of the rural economy;
l China Postal Savings Bank and China Construction Bank completed the first cross-blockchain platform forfaiting transaction, Hua Xia Bank Kunming Branch’s first Realize forfaiting resale business in the secondary market;
l Nanjing Iron and Steel completed blockchain-based iron ore transactions with Rio Tinto of Australia and Vale of Brazil respectively;
< br /> 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, there are also issues related to blockchain and cryptocurrency.Hype, scams, money laundering, cyber attacks and other dark sides are everywhere. 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 cooperates with a Korean retailer to provide blockchain-based points management services to its members. 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, it can improve the overallThe operating efficiency of social and economic systems;
"Token economy" is a new process of value creation and realization, which does not necessarily use currency directly as the medium of transaction, but is more embodied in various elements , exchange, mutual benefit and reallocation of resources;
"Token economy" is often combined with incentive mechanisms. Through incentives for "good people and good deeds", "good enterprises" and "good institutions", It will effectively reshape the social value system and social credit system.
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 the necessary monitoring process in clinical trials of medical equipment can be replaced by a blockchain system;
l Alipay and Wukong Car Rental have cooperated to launch a "face-swiping" car rental service, which uses blockchain technology and credit-free security mode, tourists can rent a car by simply "swiping their 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" vehicles that combine blockchain technology , no contact, zero errands" style government services, replacing the traditional offline service methods, providing a strong guarantee for the smooth progress of remote bidding, "cloud" customs clearance, financial support, resumption of work and production 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 Walmart Canada has significantly reduced invoice disputes with carriers by 97% through the application of the DL Freight blockchain platform;
l The State Grid Corporation of China’s power transaction certificate traceability inquiry platform has been put into operation, automating the entire authenticity review process for registered users and saving 99% of trusted manual review time;
l COSCO Shipping Lines and Shandong Port Group Qingdao Port have cooperated to launch a blockchain paperless import and delivery model, which can save customers nearly 24 hours on average per container;
l Taizhou, Zhejiang uses "materials" The "Internet + 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 cooperation of trust mechanism, sharing mechanism and transaction mechanism,Using blockchain technology, blockchain has created a significant substitution effect, improved the operational efficiency of finance, government affairs, and various industries, and will continue to form systemic changes. 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.
The sharing economy is booming in the Internet environment, but in the current sharing model, "physical sharing" is still the mainstream model, such as shared bicycles, shared charging, shared luggage, shared hotels, etc.
It is true that the contradiction between idleness and lack of physical resources in different projects is the most obvious. For example, people often face traveling without a car or do not want to drive. Therefore, the physical sharing model emerged as the times require. In addition, technological simplicity also allows the most direct application of sharing physical objects to be implemented first.
In fact, blockchain is consistent with the sharing economy in terms of technical applications and business models. The POC computing power candy + sharing economy model launched in 2018 has catalyzed the "new sharing" There is a realized application foundation and long-term prospect planning, which may help the new sharing economy get out of the fog and keep the blockchain away from the hustle and bustle.
Based on this sharing model between super nodes and users, POC intends to expand it so that users (including enterprise users), other users and enterprises can share resources. A "new sharing" model to achieve a "new Internet" with resource synergy and maximum energy efficiency.
The key to the problem becomes how to establish mutual trust with the participation of multiple parties, and decentralization ensures that there is no interest control. This coincides with the concept of POC computing power candy. The launch of POC super nodes is undoubtedly the inevitable result of computing power candy realizing "new sharing" with the help of blockchain technology.
Referring to the concept of the white paper, a series of application scenario settings of POC are also in line with the two-way catalytic relationship between blockchain and "new sharing". This may be the reason for the announcement amidst the clamor of blockchain public opinion. The reason why the POC at the meeting was still confident.
2. "New Sharing" + Computing Candy POC Jumps to the Technical Level
First of all, it is the catalytic effect of computing power candy technology on "New Sharing", which is more reflected in On a technical level.
(1) This new sharing feature is actually decentralization, the concept of "weakening platform ownership and strengthening shared management rights", which again coincides with POC computing power candy, using new Technology enables new sharingDecentralization is inevitable. The principle is that the computing power candy platform does not need to participate in the transactions between users, and these "rights" are owned by the super nodes, and POC has countless nodes, thus achieving decentralization and new sharing by super nodes. Model principles.
(2) "To own but not to possess", both have the same vision of decentralization. There are multiple stakeholders in the new sharing of POC computing power candy, which essentially follows the "own but not possess" characteristic of the sharing economy: all participants can enjoy the resources in the system equally and efficiently, but no one can possess the system. Seek extra personal gain of your own. Each user has the right to become a super node, perform their obligations under the supervision of the entire network, and independently obtain super node benefits.
3. Power Candy + "New Sharing" to realize the Internet of Value
(1) The goal of Power Candy is ultimately to return to how to deliver value . Although when it comes to blockchain, public opinion talks about keywords such as decentralization and trust mechanisms. From the practice of POC, we can also see that these characteristics have obvious technical and commercial value, but in terms of computing power candy For Power Candy itself, decentralization, trust, etc. are just the means to achieve its ultimate goal of value Internet. This means that the participants in the POC project must transfer value to each other through it rather than traditional information, which has also become one of the criteria for identifying those "pseudo-blockchains".
(2) The combination of POC and blockchain is the appropriate practical field for the value Internet
The value of the value Internet in the computing power candy Power Candy means not only monetary value, Rather, it generally refers to resources that can produce utility. In POC planning, these values realize direct flow, rather than needing to be translated from information into value (for example, WeChat's payment is essentially sending instruction information and then the transfer is executed by Tencent's backend).
In addition to reliable digital currency projects, POC is undoubtedly the most suitable blockchain application field for value flow. According to IHS forecasts, the global installed base of IoT devices will reach 20.7 billion in 2020 and 75.4 billion in 2025. In such a huge network, there are a large number of value (computing power, storage, bandwidth, scenario analysis, identity authentication, payment authentication, etc.) flow requirements.
4. As the performance increases and the loss decreases, there are more possibilities for new sharing
Whether it is from new sharing to POC computing power candy, or from POC computing power candy to New sharing, both benefit each otherIn the process, when digital currencies have copied the mining model as an incentive mechanism and are widely questioned, the combination of the sharing economy and POC computing power candy provides a paradigm that blockchain can reversely reduce the loss of social resources and improve efficiency.
In any case, in today's world of constant quarrels about blockchain, under the new sharing concept, the POC computing power candies tied to the sharing economy provide a solution that is not objectionable either at the logical level or at the intuitive level of the public. Blockchain practical cases, new sharing will have more application possibilities.

㈣ 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 have something to do with blockchain. 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 call e-commerce "EC" for short. Many people think it is the ultimate major commercial use of the Internet, so they call it an epoch-making symbol.
According to data from US market research company Forrester, by the end of 2018, China’s e-commerce market is expected to reach US$1.1 trillion, becoming the world’s first trillion-dollar e-commerce market.Regarding the e-commerce market, the report pointed out that by 2022, 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 about many problems. According to big data from the e-commerce consumer dispute mediation platform, the number of complaint cases accepted in the first half of 2018 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 aspects such as counterfeit goods, logistics, integrity, and supervision, major companies and platforms are also showing off their skills and tricks. The most eye-catching one is our protagonist: blockchain. So how does it solve these problems?
First, supervise the production process of goods.
Second, trace and track the transportation of goods.
Third, guarantee product sales and after-sales service.
Fourth, protect user privacy.
The distributed e-commerce platform Bitcherry BCHC solves the platform trust crisis
Bitcherry BCHC is the world’s first distributed e-commerce platform. It is based on blockchain technology and is committed to To create a super ecology covering 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 to open up the online and offline O2O e-commerce system, making the entire ecology healthy and autonomous. , develop healthily.
It is understood that the distributed e-commerce network has multiple payment methods, distributed sharing mechanisms, behavioral token incentives, distributed open platforms, multi-industry and multi-community access, and operating nodes around the world. , decentralized distributed business organizations, community self-propagation and ripples and other characteristics.
At present, consumer information is leaked, everyone has become a "digital labor", merchant profits are reduced, customer acquisition costs are increasing day by day, supply chain supervision is lacking, and product quality problems occur repeatedly, which is the problem for most centralized e-commerce companies. main pain points. Different from the centralized model of traditional e-commerce platforms, the underlying technology of distributed e-commerce platforms 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. In distributed e-commerce based on blockchain technology, industry issues such as product traceability, logistics supervision, user evaluation and community incentives are all 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 approach to achieve the goal of “Blockchain 4.0”. 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.
5 What earth-shaking changes will blockchain bring and how will it change life?
In addition to being used in the financial industry, blockchain is also used in other fields. In fields such as law, retail, Internet of Things, and medical care, blockchain can solve trust problems, no longer rely on third parties to establish credit information sharing, and improve the operating efficiency and overall level of the entire industry. Extremely high productivity will connect all people and machines in this society into a global network, and mankind will accelerate towards an era where goods and services are almost free. Perhaps by the second half of the 21st century, capitalism will decline and areas The decentralized collaborative sharing model of the blockchain will replace it and become the new model that dominates economic life.
Blockchain is the best technical means for this new collaborative sharing model. The infrastructure of blockchain allocates global resources in a decentralized manner, making blockchain an ideal technical framework for promoting social and economic development. The operational logic of blockchain lies in its ability to optimize peer-to-peer resources, global collaboration, and the sensitivity that fosters and encourages the creation of social capital in society. Establishing various platforms for blockchain can encourage a collaborative culture to the greatest extent, which complements the original shared model and will make it the decisive economic model of the 21st century.
㈥ How to define blockchain and what are the application scenarios of blockchain?
Nowadays, many people think that blockchain is a universal technology that can do anything, which is somewhat different. Blockchain technology is a myth!
In blockchain technologyIn terms of the definition of technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized database in her book "Blockchain: A New Economic Blueprint and Introduction".
Definition of Blockchain: Narrow VS Broad
As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.
Blockchain technology features include:
Blockchain is a global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).
At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.
At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.
As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.
Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.
Blockchain is a distributed ledger (database) that connects data blocks in an orderly manner and cryptographically ensures that it cannot be tampered with or forged. technology. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. As an underlying protocol or technical solution, blockchain can effectivelySolving the trust problem and realizing the free transfer of value 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 implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also released a white paper on its cryptocurrency Libra. Whether it is Bitcoin or Libra, the underlying technology they rely on is blockchain technology.
my country began the development of central bank digital currency as early as 2014. my country's digital currency DC/EP adopts a two-tier operating system: the central bank does not directly issue digital currency to the public. Instead, the central bank redeems the digital currency to various commercial banks or other legal operating institutions, and then these institutions exchange it for public supply. its use. In early August 2019, the central bank held a video conference on work for the second half of the year. The meeting called for accelerating the pace of research and development of the national legal digital currency.
Financial asset transaction settlement
Blockchain technology naturally has financial attributes, and it is causing disruptive changes in the financial industry. In terms of payment and settlement, under the blockchain distributed ledger system, multiple market participants jointly maintain and synchronize a "general ledger" in real time. Payment, clearing, and settlement that currently take two or three days can be completed in just a few minutes. tasks, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track transactions on the chain and quickly locate high-risk capital flows. In terms of securities issuance transactions, traditional stock issuance has long procedures, high costs, and complex links. Blockchain technology can weaken the role of underwriting institutions and help all parties establish fast and accurate information exchange and sharing channels. Issuers handle issuance on their own through smart contracts, and regulatory authorities With unified review and verification, investors can also bypass intermediaries and conduct direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.
Digital Government
Blockchain can allow data to run and greatly streamline service processes. The distributed technology of blockchain can allow government departments to be centralized on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "instant reimbursement after invoicing" - in seconds Level invoicing and minute-level reimbursement accounting significantly reduce tax collection and management costs, and effectively solve problems such as data tampering, over-reporting of one ticket, and tax evasion. Poverty alleviation is another practical application of blockchain technology. Utilize the characteristics of openness, transparency, traceability, and non-tampering of blockchain technology to achieve transparent use, precise investment, and efficient management of poverty alleviation funds.
Evidence-based anti-counterfeiting
Blockchain can prove the existence of a file or digital content at a specific time through hash timestamps, and it is open, non-tamperable, and traceable. It provides perfect solutions for judicial forensics, identity certification, property rights protection, anti-counterfeiting and traceability, etc. In the field of intellectual property, the digital signature of blockchain technology and on-chain certificates can confirm the rights of text, pictures, audio and video, etc., and create and execute transactions through smart contracts, allowing creators to regain pricing power and preserve data formation in real time. The evidence chain covers the three major scenarios of rights confirmation, transaction and rights protection. In the field of anti-counterfeiting and traceability, blockchain technology can be widely used in various fields such as food and medicine, agricultural products, alcohol, and luxury goods through supply chain tracking.
Data services
Blockchain technology will greatly optimize existing big data applications and play a huge role in data circulation and sharing. In the future, the Internet, artificial intelligence, and the Internet of Things will generate massive amounts of data. The existing centralized data storage (computing model) will face huge challenges. Edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the non-tampering and traceability mechanism of blockchain ensures the authenticity and high quality of data, which becomes the basis for all data applications such as big data, deep learning, and artificial intelligence. Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation. In response to the current blockchain development stage, in order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will effectively reduce enterprise blockchain deployment costs and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.
The three words "blockchain" are justThe Spring Festival that just passed was completely ignited, and the limelight overshadowed everything. Some people said that this is the arrival of a new era, and the past has become classics. Others said that everything is hype and is a bubble after all.
In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.
Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.
Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.
eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated in the process in real time. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.
Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.
Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.
From a technical perspective, blockchain is not a brand-new technology, but distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and intelligent technology.New application models of computer technology such as energy contracts. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.
Due to its advantages such as "decentralization", "distributed data storage", "traceability", "anti-tampering", and "openness and transparency", blockchain technology can effectively solve data problems. By establishing a trustworthy data management environment, we can prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote the efficient sharing and application of data. In the process of practice and exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions, and continues to empower public resource transaction management services.
Facilitate transaction data sharing and transaction witnessing
Facilitate transaction data Share
Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. It is difficult to verify the off-site performance provided by the bidders during the bid evaluation process. It is difficult to troubleshoot the same person repeatedly serving as project manager. Issues such as low cost of breach of trust. Establishing a cross-regional subject database based on blockchain can well alleviate the above problems.
The distributed ledger feature based on the blockchain can effectively ensure the real-time or quasi-real-time sharing of data, and can reduce the repeated entry of subject information; the use of blockchain information that cannot be tampered with can ensure the data circulation process on the chain. The authenticity of the bidders in the regional alliance is directly obtained from the on-chain data, making it impossible to hide the fake performance. At the same time, the sharing of bidding behavior data through the blockchain provides a data basis for the development of "joint punishment of dishonest enterprises".
Blockchain-based transaction witness
"Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" ( The State Office Letter [2019] No. 41) pointed out the need to optimize services such as witnessing, venues, information, files, and expert extraction. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing intensity, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witness system is prone to data tampering, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.
Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to solidify and store the data generated in each transaction link, and accurately record the data generated through time stamp technology, summary algorithm, and electronic signature technology. Time, content, data source. According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain, and unstructured layout files, videos, audio and other large files can be saved through the blockchain.To obtain information, the original file is saved through the distributed file storage service. When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction. Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.
Promote the rationalization of electronic guarantee rates
Promote financial services and corporate financing for bidding companies
Promote the rationalization of electronic guarantee rates
At present, electronic bidding deposit guarantee letters have certain applications in the field of bidding, solving the problem of bidding deposit funds for bidding companies. Occupancy issues. However, because financial institutions currently do not have reliable historical bidding behavior data of bidders, they are unable to judge the default risks of different bidders. As a result, the guarantee services charged to bidders adopt fixed rates, which makes a small number of bids with high default risks The cost of personal guarantee is allocated to most bidders with low default risk, which increases the guarantee rates for most bidders to a certain extent.
At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main choice basis for the bidder. If the bidder performance records are shared through the blockchain and the performance risks of different bidders are analyzed, it will be Different bidders provide different guarantee rates, which not only reduces the risks of financial institutions, but also reduces the use costs of most bidders and promotes the use of bid guarantees. To a certain extent, it can also encourage bidders to abide by their promises and maintain the order of the bidding market. .
Promote financial services for bidding companies
The bidding behavior of bidders is scattered in various trading centers, and the data is simply aggregated In a centralized information system, there is a risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be gathered and shared safely and reliably. Through blockchain technology, bidders from multiple trading centers are gathered, and historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate the bidders' credit in the bidding sub-sector.
Solving the financing problems of successful bidders
Traditional corporate loans mainly evaluate the company's solvency: collateral, audit There are requirements for accurate financial statements and sustained profitability, but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become problems faced by many small and medium-sized enterprises in bidding activities. Using the methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools. With the help of the non-tamperable characteristics of blockchain, 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 handIt improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.
Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. Centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data trustworthiness but also reduces the risk of corruption. The entire system relies on a centralized authority.
Through further analysis, we found that credit sales are currently prevalent among domestic enterprises, and the upstream suppliers of the winning bidder have a large funding gap. The credit of the bidder can only be passed to the winning bidder (the winning contract cannot be split or transferred), and the upstream suppliers Business owners are unable to obtain high-quality loans from financial institutions. If the winning contract is converted into a "pass" on the chain, the "pass" can be split, and the winning bidder holding the "pass" can pay part or all of the voucher to the upstream supplier, making it discountable and financing. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduce bidders' costs.
Regarding blockchain, we can imagine a decentralized management model and technical processing method.
Let me give you an example. There are five people in your family, and they have never been able to figure out how to arrange work and handle family relationships.
So, you and your family discuss it together and simply use voting to solve the problem.
Then this way of voting to solve problems can be called the most elementary blockchain.
Decentralization solves problems.
What application scenarios can blockchain have?
In fact, many of our families and many organizations use blockchain management forms every day
However, this kind of blockchain application for organizational relationships cannot produce Economic Value.
What are the economic applications of blockchain?
The first type is used for tax deposit certificates, bank transfers, etc.
Make full use of the traceability function of the blockchain so that all records can be retrieved and queried at any time
The second type is applied to enterprise operation and management
Enterprises using blockchain management can better solve the problems of enterprise development, allowing enterprises 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. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.
Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.
In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.
At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.
Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.
The most popular application industry at present is the financial industry.
An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since traffic fraud in digital advertising causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud
In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a new ecosystem based on technological trust. Mode
What is blockchain If you explain blockchain in non-technical terms, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone. Therefore, in the Internet, a place where data and information are exploding, having such a place will be like a magical treasure land.
If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, the blockchain is a safe place. So, as long asBlockchain technology is needed wherever data needs to be securely protected on the Internet. For example:
Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.
If there are any deficiencies, you are welcome to comment and correct me.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.
The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.
Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.
In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.
1. Cloud storage
This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?
Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.
2. Medical aspects
Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.
㈦ What are the application examples of blockchain technology?
Application of blockchain technology in voting
