① What are the application prospects of blockchain in the Internet of Things and logistics fields?
Blockchain is the most commonly used in the financial field, and it has been favored in the past two years. Especially in the field of logistics, because the logistics field has long been complex and difficult to standardize, the emergence of blockchain can gradually solve these problems, such as paperless transmission of information, such as removing intermediaries, visual tracking of goods throughout the process, digital asset management, insurance Claims settlement, intelligent reconciliation, industry blacklist sharing, etc. Currently, I have just joined a company called Yunliu Blockchain, which mainly applies blockchain technology to the shipping and logistics industry. The initial solutions are paperless order processing, cargo tracking, and fleets. Issues such as online order dispatching.
② In what scenarios will blockchain be applied?
According to reports, blockchain finance has made great progress in these two aspects in 2017. The first The breakthrough is to be able to establish a multi-dimensional three-dimensional interactive architecture. The second breakthrough is to be able to establish an open source, public and trustworthy data registration and certificate storage platform.
However, the value of a single blockchain application is limited. Blockchain technology must be integrated with big data, artificial intelligence, cloud computing and 5G and 6G technologies. Only by using it can we be more efficient and create more value for society.

③ Re-understanding the blockchain: Enlightenments brought by more than 1,550 application cases
Author: Ran Wei
(This article is excerpted from the "2021 Global Blockchain Application Market Report")
When we talk about blockchain, anyone who knows something about blockchain can Related topics more or less express some of your own opinions. 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 developing rapidly.ization, 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 answers. 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 Public welfare organizations have put charity funds on the chain to form a more transparent and standardized public welfare tracking and management system;
l Relevant cities in China have launched a blockchain-based gas cylinder product traceability management system, which has greatly improved the credibility of the source of gas cylinder file information and the level of gas cylinder safety management;
l Germany is establishing 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 nodes. 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 enables all types of electronic evidence to be seamlessly connected with judicial institutions such as notarization, arbitration, judicial appraisal, and courts, improving the efficiency of the judicial system while reducing costs;
l The "cross-domain collaboration mechanism for trial auxiliary matters" for grassroots courts across the country can realize "cross-domain service and cross-domain evidence collection" between courts in different regions, effectively improving the efficiency of trial auxiliary matters and the quality of trials. It is effective and reduces the cost of judicial operation...
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 a cross-industry real estate information sharing and management model and promote cross-industry innovation;
l The French Renault Group completed the test of its blockchain project "XCEED" for zero Sharing compliance information between component suppliers and automakers and simplifying 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 a functional architecture point of view, blockchain-based transactions are by no means just a change in the transaction process, but integrate the unique functions of the blockchain, which are the key to anti-counterfeiting traceability, supply and demand docking, and warehousing. 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 breeders, supply chain The chain traceability function is not 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 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 Ganzhou, Jiangxi Province, has launched an international timber electronic trading platform based on blockchain, which will manage the entire timber transaction process on the chain, and will provide the timber market with full industry chain services such as cloud warehouse supervision, logistics, finance, and insurance;
< br /> l Shandong Province launched the Shandong Internet Traditional Chinese Medicine Trading Platform, which will use blockchain and other technologies to achieve online integrated services of quality control, trading, payment, settlement and supervision;
l Suzhou Phase Weitang Town in the urban area has released a blockchain-based pearl online trading platform, which will store the core parameters and test reports of pearls on the chain, and will also add functions such as supply chain management, trade finance, smart contracts, payment settlement, and incentive mechanisms;
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 The American company Securitize has established a data-basedZi Securities' Japanese real estate investment platform aims to revitalize idle real estate in rural Japan and enhance rural economic vitality;
l Postal Savings Bank of China and China Construction Bank completed the first cross-blockchain platform forfaiting Transaction, Hua Xia Bank Kunming Branch realized forfaiting resale business in the secondary market for the first time;
l Nanjing Iron and Steel completed the blockchain-based iron ore resale business with Rio Tinto of Australia and Vale of Brazil respectively. Transaction;
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" of electric carsThe Charging Network Working Group (EVGI) launches a global standard system for decentralized car charging technology, covering the Tokenized Carbon Credit (TCC) scenario;
l Blockchain reward platform MiL.k and South Korea Retailers collaborate to provide blockchain-based points management services to their 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, 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 , blockchain and other new technologiesUse it to explore replacing manual trial transcripts with digital court trial records;
l The Japanese company SUSMED launched a "Clinical Data Monitoring System Demonstration Using Blockchain Technology" pilot to demonstrate the necessary requirements in clinical trials of drugs or medical equipment. The monitoring process 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 "swipe their faces" "You can rent a car and return it through mobile phone operations;
l Under the new crown epidemic, local governments in China have intensively launched a "no face-to-face, no-contact, zero errands" approach that combines blockchain technology Government services have replaced traditional offline services and provided a strong guarantee for the smooth progress of remote bidding, "cloud" customs clearance, financial support, and 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 electricity transaction certificate traceability inquiry platform was put into operation, automating the entire authenticity review process for registered users and saving 99% of the trusted manual review time;
l COSCO Ocean Container Lines has cooperated with Shandong Port Group Qingdao Port to launch a blockchain paperless import and delivery model, which can save customers nearly 24 hours on average per container;
l Taizhou, Zhejiang uses the "Internet of Things" + 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.
④ There are many blockchain applications now. What kind of blockchain applications are good? Where can I get a clear understanding of them?
I want to know about blockchain applications. , you can refer to many books and opinions, including "Blockchain in Pictures", "Blockchain: Reshaping the Economy and the World", "New Economic Blueprint and Introduction", as well as articles from the Binance Community, including comments on the Binance Community platform Also learn more about it, its strength is awesome.
1. What is blockchain
Blockchain, as the name suggests, is composed of blocks and chains. It is a distributed data storage , point-to-point transmission, consensus mechanism, encryption algorithm and other new application models of computer technology. It is a chained data structure that combines data blocks in chronological order and is cryptographically guaranteed to be an untamperable, unforgeable, safe and trustworthy distributed ledger.
In 2008, Satoshi Nakamoto first proposed the concept of blockchain and encrypted digital currency in his paper "Bitcoin: A Peer-to-Peer Electronic Cash System". Starting from Bitcoin, blockchain has become the underlying technology of various digital currencies.
2. The working principle of blockchain:
1. Basic concepts include:
(1) Transaction: one operation will change the ledger status once , such as adding a record;
(2) Block: records transactions and status data that occurred within a specified time, which is a consensus and preservation of the current ledger status;
(3) Chain ( Chain): It is composed of blocks connected in chronological order and is a log record of the entire state change.
Understanding the working concept of blockchain, it is not difficult to understand its working principle. Assume that there is a distributed data record book. This record book only allows additions and noDeletion and modification are allowed. Its structure is a linear chain composed of "blocks" connected in series (this is also the source of the name "blockchain"). To add new data, it must be placed in a new block. , the maintenance node can propose a new block, but it must go through a certain consensus mechanism to reach an agreement on the final selected block.
2. Take Bitcoin as an example to see how the blockchain works.
Bitcoin blocks are divided into two parts: block header and block body.
3. Core advantages and characteristics of blockchain
1. Decentralization
Block The processes of verification, accounting, storage, maintenance and transmission of chain data are all based on the distributed system structure. There is no centralized hardware or management organization. The rights and obligations of any node are equal. The data blocks in the system are composed of Nodes with maintenance functions in the entire system are jointly maintained.
2. Open and transparent
The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone, and anyone can query the blockchain through the public interface. Data and development related applications, so the entire system information is highly transparent.
3. Security
The blockchain adopts consensus-based specifications and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to exchange data freely and securely in a trustless environment. , so that trust in "people" is changed to trust in machines, and any human intervention has no effect.
4. Information cannot be tampered
Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system (almost impossible) can be controlled at the same time, otherwise Modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high.
5. Anonymity
Since the exchange between nodes follows a fixed algorithm, the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to Making the other party trust you by disclosing your identity is very helpful for the accumulation of credit.
4. Classification of blockchains
Currently, the most mainstream classification of blockchains is to divide blockchains into public blockchains (Public Blockchain) based on different participants. ), Private Blockchain and Consortium Blockchain.
1. Public chain: Anyone can participate in the use and maintenance, and can obtain effective confirmation of the blockchain. The public chain is the earliest blockchain and the most widely used blockchain at present. , typically such as the Bitcoin blockchain, the information is completely public.
If a permission mechanism is introduced, it will include private chain and alliance chain.
2. Private chain: A company or individual only uses the zoneBlockchain technology has exclusive writing rights to the blockchain and the information is not made public. At present, conservative giants (traditional finance) all want to experiment with private blockchains, and the application products of private blockchains are still being explored.
3. Consortium chain: It is a blockchain between the public chain and the virtual chain, jointly controlled by multiple organizations. The use of this chain is managed with authority and can be controlled by managers and also based on The manager's wishes are open to others.
In addition, according to the different usage scenarios and purposes of blockchain, it is divided into currency chains for the purpose of digital currency, property rights chains for the purpose of recording property rights, crowdfunding chains for the purpose of crowdfunding, etc. .
5. Analysis of specific application scenarios of blockchain
1. Information anti-counterfeiting
On May 28, Tencent CEO Ma Huateng spoke at the Guiyang Digital Expo The problem of Moutai anti-counterfeiting has been raised: the anti-counterfeiting method based on cloud-based comprehensive blockchain technology will be much more efficient than traditional anti-counterfeiting methods. In future anti-counterfeiting verification scenarios, users may only need to perform a simple scan with their mobile phone to obtain a large amount of complete information based on different dimensions.
Take Moutai as an example:
Distillery address, production workshop, operating employees, inspectors, factory time, transportation vehicle information and driver information,
The vintage source of raw materials for wine, raw material suppliers, storage warehouse numbers, raw material transportation vehicles and driver information,
All information can be accurately traced, permanently recorded and cannot be tampered with.
The authenticity can be easily verified based on the above information.
2. Food safety issues
As early as November last year, Walmart had cooperated with IBM to ensure food safety by using blockchain technology to track food sources. safety and increase the circulation of food to reduce costs. For large supermarkets such as Wal-Mart, when food safety problems occurred in the past, it took several days to investigate the source of the problematic food. After using this technology, only one piece of information about the product is required. It can accurately trace the source of important information such as food origin, inspectors, suppliers, logistics and transportation, and quickly detect problems within a few minutes. Currently, products tracked using blockchain include packaging products in the United States and pork in China.
3. Information Security
Blockchain technology is promoting a revolution in information security technology. Three major security threats: man-in-the-middle attack, data tampering, and DDoS
(1) Identity protection
PKI is a common public key encryption used in various communication applications such as email, messaging applications, and websites. technology. However, since most PKI implementations rely on a centralized trusted third-party certification authority (CA) to issue, activate and store user certificates, hackers can attack PKI to fake user identities or crack encrypted information.
CertCoin is the first blockchain PKI implementation, coming from MIT, which removes the centralized certification center and uses the blockchain as a distributed ledger of domain names and public keys.
POmcor Company: Blockchain PKI implementation path: retain the certification center and use the blockchain to store hash values of issued and activated certificates. Users can verify the authenticity of certificates through decentralized and transparent sources, while also improving network access performance through local authentication of keys and signatures based on blockchain copies.
(2) Data integrity protection
GuardTime has developed a keyless signature architecture (KSI) based on blockchain technology to replace key-based data authentication technology. KSI stores hashes of the original data and files on the blockchain, runs hashing algorithms to verify other copies, and compares the results with the data stored on the blockchain. Any tampering with the data will be quickly detected because the original hash table is stored on millions of nodes.
(3) Protection of critical infrastructure
The "Achilles' heel" of the Internet, DDoS has entered the TB era, and DDoS is still the easiest way for hackers to defeat large targets at low cost. As a weapon, DNS services are the primary target for hackers to carry out large-scale damage, but blockchain technology is expected to fundamentally solve it.
The distributed storage of blockchain makes hacker attacks lose focus. Nebulis is developing a distributed DNS system using the Ethereum blockchain and the InterPlanetary Internet File System (IPFS, a distributed alternative to HTTP product) to register and resolve domain names. The biggest weakness of DNS is caching. Caching makes DDoS attacks possible and is also the bane of centralized governments censoring social networks and manipulating DNS registrations. A highly transparent, distributed DNS system can effectively prevent any entity, including the government, from manipulating records.
IV. Financial Industry
(1) Digital Currency: Improving the convenience of currency issuance and use
For example, foreign Bitcoin and Ethereum, our country currently There are Nuo Compao and so on.
From the use of physical transactions, to physical currency and credit currency, to the rise of the Bitcoin network, more people are aware of the distributed ledger blockchain technology behind it, and gradually outside of digital currency applied in many scenarios.
(2) Cross-border payment and settlement: realize point-to-point transactions and reduce intermediate costs
Transfer and payment. At present, the most mature application of blockchain technology is payment and transfer. Blockchain technology can avoid complicated systems, save the process of inter-bank reconciliation and review, and speed up settlement; using virtual currency does not require the intervention of a clearing house, reducing transaction fee. The clearing procedures of each country are different. It takes 2 or 3 days for a single remittance to arrive, which is inefficient and accounts for a large proportion of funds in transit. No longer going through a third party, point-to-point payment is formed through blockchain technology. Eliminating the need for third-party institutions, you can make payments throughout the day, receive money in real time, quickly withdraw cash, and reduce hidden costs, helping to avoid financial risks. It is timely and convenient.
(3) Bills and supply chain finance business: reduce human intervention, reduce costs and operational risks
Peer-to-peer value transfer, physical billsData or central system for control verification; intermediaries will be eliminated, reducing human intervention. Improved efficiency, smoother financing channels, lower risks, and benefits for all parties.
(4) Securities issuance and trading: realize quasi-real-time asset transfer and accelerate transaction clearing speed
The application of blockchain technology can make the securities trading process simpler, more transparent and faster , Reduce IT systems with repetitive functions and improve the efficiency of market operations. For stocks, blockchain can eliminate paper and pen or spreadsheet records, reduce human errors in transactions, and improve the transparency and traceability of trading platforms. Citi and Nasdaq collaborate to advance blockchain applications.
(5) Customer credit reporting and anti-fraud: reduce legal compliance costs and prevent financial crimes
Customer information and transaction records recorded in the blockchain help banks identify Abnormal transactions and effectively prevent fraud. The technical characteristics of blockchain can change the existing credit reporting system. When banks perform "know your customer" (KYC), the data of customers with bad records will be stored in the blockchain.
Equity crowdfunding: Equity crowdfunding based on blockchain technology can achieve decentralized trust and investors’ returns are guaranteed.
5. Supply chain management
Distributed ledger system, participants track the ownership of assets throughout the process, and can be used to track auto parts when moving between countries and factories.
Toyota is developing blockchain technology solutions for its core parts supply chain operations. Using a large amount of data helps Toyota more efficiently ensure the accuracy of recorded data and can also help manage the supply chain. At the same time, the blockchain supply chain can control warranty, repair goods-related costs and specifications through smart contracts, and transactions throughout the product life cycle are irrevocable.
The shipping industry’s first public solution, deployed by Maritime Transport International (MTI), uses blockchain supply chain technology to share Verified Gross Mass (VGM) information for shipping containers. Information about container VGM is important to ensure ships are properly stowed and to prevent accidents at sea and in ports. VGM data is stored on the blockchain supply chain, providing a permanent record for port officials, shipping companies, shippers and cargo owners. This replaces cumbersome logs, spreadsheets, data brokers and private databases.

Application cases of blockchain + IoT convergence technology in the shipping field
About Maritime Introduction to Rich Shipping Chain
1. Background
As a traditional and irreplaceable important industry, the shipping industry plays an important role in international The important role of the trade industry chain has always been an important force supporting the development of globalization. The international shipping market is a fully competitive and open market, which has certain risks but also huge business opportunities.
In the traditional investment field of the shipping industry, there are untimely information disclosures and opaque operating data of ship management companies, which has brought a lot of scrutiny to investors and financial institutions. It also brings a lot of inconvenience to the financing of small and medium-sized shipping companies. How to establish a reliable trust system between investors and financiers, establish an effective communication bridge, and effectively serve the capital in the shipping market, has always been This is a problem that the Haifu Fund team is working hard to break through. Now, the Haifu team has created the first digital asset shipping platform, and through the integration of blockchain + Internet of Things technology, it has completely solved the problem of unreal information disclosure and operating data, and also discovered potential opportunities in the shipping market, unleashing the potential of the shipping market, and leading more people to share the dividends of the shipping industry.
The Haifu team is a team with more than 20 years of rich experience in international shipping.Shipping investment team, its core team members have served as senior managers in large shipping companies such as China Ocean Shipping Group (COSCO), Hong Kong Kaitong, Hong Kong Weili Lines, and Singapore Wanbang Shipping. The team members are very familiar with the shipping market and financial market. Not only good at ship management, but also good at ship trading and ship investment management. During his many years of shipping career, the founder has owned nearly 20 large dry bulk ships with a total deadweight of more than 1 million tons and an annual turnover of more than 1 million tons. 100 million US dollars, with an average annual investment return of 30%.
Haifu Fund and Xinyang Shipping Ship Management Co., Ltd. have established a long-term partnership. Xinyang Shipping Co., Ltd. has an excellent ship management team. The company's team has overcome many technical problems of bulk cargo ships: In terms of navigation technology, we have dealt with many ship maneuvering issues under severe weather conditions; in terms of business, we have also dealt with dozens of charter transport contract disputes, as well as ocean bill of lading issues, ship insurance and other complex issues. .
In order to truly present the operating data, the Haifu team uploaded the core operating data of the partners to the public chain On the market, through the combination of software, hardware and blockchain data, operational indicators are publicized, allowing investors to understand the true situation of ship operations in real time.
Main on-chain data:
1. Through AIS data on-chain, master the real-time position information and navigation trajectory of each ship;
2. Through chartering The shipping contract is uploaded to the blockchain to allow investors to understand the operating income;
3. The voyage benefit calculation data is uploaded to the blockchain to allow investors to understand the operating profit.
In addition, shipping data sensors are installed on the bridge and engine room control room of the ship. The sensor integrates multiple technologies of blockchain + Internet of Things technology. The sensor has both The functions of data collection and real-time data uploading embed blockchain technology into the hardware level, allowing the objective operating data collected by the hardware to be uploaded to the chain in real time, thus avoiding the possible moral hazard of human tampering with data.
1. Compare the ship’s fuel consumption data collected through sensors with the theoretically calculated data;
2. Compare the ship’s mileage data collected through sensors with the actual data at the loading and unloading port;
3. The ratio of cargo capacity calculated by collecting ship draft data through sensors to the quantity agreed in the transportation contractright .
Through multiple cross-references, real-time operating conditions are reflected to investors and financial institutions. In addition, Haifu Company also timely updates and discloses the latest project progress and investment income on the homepage of the website. After expiration, smart contracts are used to automatically execute the deduction of dividends and interest, ensuring that the investment returns of investors and financial institutions are received in a timely manner.
In addition to information disclosure and the authenticity of management data, if the ultimate risk occurs, the Haifu team also has countermeasures: ship asset disposal. The risk of disposal of ship assets is relatively controllable. The international price of scrap steel is basically based on the international price of scrap steel. The international price of scrap steel is relatively stable. It has basically remained at around US$400 per ton for many years. With a load capacity of about 50,000 tons of Panamax ships, its scrap steel weight is 1 For example, about 10,000 tons, which means that the price of ship scrapping is about 4 million US dollars. Generally speaking, for ships that are about 20 years old, scrap steel can basically cover 80% of the ship price, regardless of the rise or fall of scrap steel. Of course, premiums and losses caused by sharp rises or falls in scrap steel cannot be ruled out.
In addition, the operating income of shipping is also relatively considerable: according to the current market level, the market rental level of a bulk carrier of about 50,000 deadweight tons is about 10,000 US dollars a day, deducting fixed costs is about 4,000 US dollars a day, and The gross profit per day is about US$6,000, and the annual income is about US$2-2.5 million, which means that with an investment of US$5 million, after deducting depreciation, the investment can still be recovered in three years.
By integrating blockchain technology and Internet of Things technology, the Haifu team will apply it to the shipping industry to bring powerful Promote the rapid and standardized development of the industry, eliminate the complicated due diligence procedures of financial institutions, greatly reduce the investigation threshold for investors or financial institutions, establish technical barriers to credit, and bring stable and reliable investment returns to investors.
⑥ Blockchain for 12 years: What fields have it been used in?
#「 Shining Moment 」Theme Essay Collection Issue 2#
People have talked about it countless times Explore the applicable scenarios and application opportunities of blockchain. But in fact, it is very stupid and ridiculous to simply and crudely bundle blockchain with all businesses.
If you just use the word "blockchain" (rather than the technology behind it) to hype it, the result will be in vain. But if used properly, blockchain can indeed promote the development of certain economic sectors.
To achieve this goal, you need to take it slowly, step by step. Gartner experts believe that blockchain is currently at the stage of “escape from fantasy”segment edge. At this stage, its technical shortcomings were fully exposed, and most media from all walks of life were critical.
So, are there any good products that are truly based on blockchain? If so, in what areas?
First of all, financial services are a good choice. After all, many traditional intermediaries suffer from low transparency and high commissions. Currently, many large banks are already researching and testing decentralized solutions. So what are the options available on the market now?
Netting is a good example. It is based on Hyperledger Fabric and is capable of offsetting multiple positions or payments resulting from transactions between two or more parties. Often used to determine which party should receive remuneration in a multi-party agreement. Netting, as a general concept, has many more specific uses in financial markets (in securities trading).
In addition, there is endless discussion about blockchain bonds, mortgages and bank guarantees. Almost all big banks, including Islamic banks, are trying this approach.
Hyperledger Fabric and Corda blockchain technologies are also often used in other use cases, but the prospects require us to draw final conclusions through continued follow-up and observation.
Bank of America, Goldman Sachs, Citibank, Morgan Stanley, JPMorgan Chase, Bank of China and Commonwealth Bank of Australia have all achieved good results in 2019. In addition, in the banking industry, people often talk about cross-border financial transactions, and there is even an intention to get rid of SWIFT.
Some people believe that blockchain technology has great prospects in copyright protection and combating data fraud. For example, for the purpose of copyright protection, the startup Sputnik DLT developed the Depositor service on the Waves platform.
Likewise, Emernotar is a similar solution based on Emercoin, using the SHA-512 algorithm. According to the developers, businesses and lawyers can use the Emernotar service to sign contracts, use the online service to collect user consents, and creative industry representatives to confirm copyright.
The democracynotary.org platform, powered by Emercoin technology, aims to protect important election-related information. Although the blockchain cannot yet guarantee the anonymity of voting during the election process, it can at least guarantee the authenticity of voting.
The effectiveness of this platform was recently put to the test in a Macedonian referendum on whether to ratify a treaty with Greece that called for changing Macedonia’s name to “NorthernMacedonia". The platform notarized public reports during the referendum process, thereby blocking the spread of false information.
Blockchain use cases are promising in the registration of real estate transactions. Last year, There have been attempts to leverage smart contracts on the Ethereum blockchain to conduct such purchase/sale transactions across jurisdictions. While not all local legislators understand what lawyers are doing, there have been attempts in the past and in the future.< br />
For example, the most famous example was a deal to sell 10 acres of land through a decentralized Propy marketplace in California, conducted entirely in Bitcoin and using blockchain Registration. Since then, the EU has also completed the first blockchain real estate sale.
In December 2018, the Swiss Financial Market Supervisory Authority approved the business model of the blockchain company "Blockimmo Real Estate Company". Currently , the Blockimmo platform is in the testing phase and is available to residents of Switzerland and Liechtenstein. After that, the company plans to enter other markets throughout Europe.
Some experts are very optimistic about the potential of blockchain in the wholesale and logistics fields. application prospects; but at the same time, some experts believe that it has no use in this field. However, as consumers, we should affirm the success that has been achieved in the industry.
In the late autumn of 2018, the oil giant BP and Shell, major banks and companies have launched the Vakt blockchain platform, which aims to optimize commodity trading processes - including converting paper documents into smart contracts.
At the same time, the UAE is also Blockchain technology is used in the field - Maqta Gateway LLC launched the first blockchain logistics solution in Abu Dhabi. The Silsal blockchain technology developed by the company can improve logistics and freight efficiency. Maqta Gateway hopes to use DLT technology to reduce paperwork, facilitate real-time status updates and speed up information sharing.
Last fall also launched the IBM Food Trust blockchain platform - based on Hyperledger Fabric technology, designed to regulate food Industry supply chain. Carrefour, Nestle, Dole Food, Tyson Foods, Kroger, Unilever, Walmart and other well-known companies Enterprises are members of the platform. Monthly fees for IBM blockchain services range from $100 to $10,000, which explains why these industry giants are willing to invest in this area.
Fall 2017 Decentralization startedized Shelf.Network auction protocol. Car dealers can conduct car sales and leasing transactions through the platform.
A year later, the auction network received investment from Japanese IT giant Broadleaf. At the same time, Broadleaf has also obtained a license to supply Shelf.Network technology to establish a trading network for automobile and parts sales in Southeast Asian countries (including Japan, Myanmar, Thailand, Indonesia, Vietnam, Laos, Australia, India and Singapore).
By the end of 2018, 60,000 vehicles from the United States had joined the service network. Shelf.Network also implements interaction with the Carfax web service, through which vehicle history reports can be provided to individuals and businesses. For example, startup Auto1 Group GmbH recorded the purchase of a car in Germany through blockchain for loan and insurance products, significantly speeding up the transaction (which would have taken two weeks to complete with traditional paperwork).
A survey of large companies conducted by the IBM Institute for Business Value shows that by 2021, blockchain will play a key role in the automotive industry, and at the same time, blockchain will also be used in the aviation field. . For example, S7 Airlines and Alfa Bank (Russia) have enabled real-time payments for aircraft fuel costs by applying smart contracts on the Hyperledger blockchain platform.
All walks of life in the industry believe that DLT technology can simplify and speed up mutual settlement processes, eliminate various financial risks, and automate processes. As in the field of wholesale logistics, this technology also has important application significance in the field of transportation.
Blockchain technology is also gradually penetrating into the public sector and is widely used in document authentication processes. For example, the Proofstack service is able to archive files with the owner’s personal signature, date and time stamp, and then writes the archive hash to the blockchain. Users can also select the country that affects the type of timestamp, as well as the storage location (computer, cloud) required to generate the archive. Created archives allow people to identify when and by whom a file was archived. At the same time, the application of blockchain in the judicial system is becoming more and more popular. For example, ServeManager and Integra have applied blockchain technology to services that track subpoena delivery.
In China, government-backed blockchain solutions continue to develop rapidly. Its judicial blockchain system "Tianping Chain" has collected about 1 million pieces of online evidence data just three months after its release. All materials submitted on the platform are DLT certified, totaling 190,000 documents. The platform electronic evidence system is provided by the Beijing Internet Court and the China Industrial Control System Emergency Response Team (CICS-CERT).), the Research Center of the Ministry of Industry and Information Technology, the Network Internet Group and the TrustDo blockchain startup company. The platform is based on the hyperchain infrastructure of the Internet giant network, optimizes the evidence collection and storage process, and ensures the authenticity of the data through the blockchain. In addition, the platform also achieves the purpose of saving time and resources by reducing Internet-related litigation costs.
As a global leader in container shipping, Maersk began using Insurwave blockchain solutions last spring. The marine insurance platform was jointly developed by consulting firms EY and Guardtime and is based on Microsoft Azure cloud technology. In the first year of cooperation with Insurwave, Maersk plans to insure 1,000 ocean-going vessels, and the total number of digital transactions will exceed 500,000.
Currently, platform users include Willis Towers Watson, XL Catlin and MS Amlin. Developers are trying to expand Insurwave's capabilities to expand insurance into the aviation and energy sectors.
Calastone, a British financial technology company specializing in investment flow management, announced that it will transfer all calculations to the blockchain. The company expects the technology to help cut billions of dollars in costs across its global settlement division. Calastone provides risk assessment management services, IT infrastructure and payment solutions to more than 1,700 companies, with clients including JP Morgan Asset Management, Schroders and Invesco.
If the enterprise's goal is to achieve transparency of transactions and information entered into the DLT registry, this will create an excellent application scenario for blockchain; however, if the enterprise is pursuing anonymity or "tracking "In financial transactions, there is no opportunity for blockchain to exert its influence.
Singapore Power Group has launched a blockchain trading market for renewable energy (REC) certificates. Its company representatives said the "in-house developed" platform was designed to improve the security, reliability and traceability of such certificate transactions.
REC certificates are certificates that certify the amount of energy released by solar panels and are sold by Cleantech Solar Asia and LYS Energy Solutions. City Developments Limited and DBS Bank, who are interested in purchasing certificates, are both very interested in the platform. Katoen Natie Singapore has also joined the platform and plans to launch renewable electricity production capacity soon.
KT Corporation, South Korea’s largest telecommunications company, has also launched its own blockchain network, with distributed registration technology involved in user authentication and improving international roaming services. This enables KT to securely transfer customer data to its partners. Network bandwidth can handle 100,000 transactions per second.
Time will tell whether these initiatives gain mass market acceptance. Likewise, the applications of blockchain in power, data, and user-identified accounts/records/transactions are old news.
At the end of 2017, the Massachusetts Institute of Technology (MIT) used the Blockcerts wallet, which can issue a "verifiable, tamper-proof" authentication certificate, to more than a hundred people through the Bitcoin blockchain. Graduates were issued digital diplomas.
The pilot project is supported by software company Learning Machine, which was involved in the development of Blockcerts together with Media Lab.
The purpose of this is to allow students to become the true owners of their own files. Learning Machine CEO Chris Jagers said that even if the agency ceases to exist, people will be able to extract important official information stored in it.
The same approach is used by Tbilisi University of Business and Technology: the university uses a similar blockchain platform, Trusted Diploma, through a partnership with Emercoin. The platform is able to restore registration data (subjects studied, quality of training and scores obtained) with the help of blockchain. From this point of view, in the future, blockchain may be useful in further promoting digital learning methods.
⑦ The relationship between shipping and blockchain
The core appeal of the “Blockchain Farm” project is to ensure production quality, achieve fast and convenient circulation, and improve farmers’ real income. The practice of building a blockchain farm through blockchain technology will bring three aspects of value innovation.
The first is to establish a set of system standards for the production of traceable products, using a combination of Internet of Things, blockchain, smart manufacturing and other technologies to achieve traceability of the entire process and ensure that the food is safe. The second step is to establish an e-commerce platform with traceability attributes. Through the entire process of data value collection and activation, it not only achieves true traceability of goods, but also increases the output of blockchain farms by more than 1,500 yuan per mu of land. Finally, the implementation of blockchain farms will help relevant parties in the industry chain, such as experts in the fields of blockchain and Internet of Things, scientific research institutions, and governments, to establish a good cooperation platform and communication mechanism.
“Currently, the project has completed the first phase of research and development and will beWith the help of blockchain technology for traceability, the first batch of large-scale farm assured grains will be delivered to consumers. In the process of building a blockchain farm, how to upload massive data collected by IoT devices to the chain, how to integrate blockchain technology with the current mature technology system and provide the same high service quality, and how to technically ensure online The consistency between online and offline, and how to ensure that there are no dead ends in the whole process are the key points of project innovation. ” said Dong Ning, CEO of Smart Chain ChainNova.
In order to cope with these challenges, Smart Chain ChainNova designed the “Blockchain Farm” platform infrastructure. Blockchain technology is integrated in the entire “Blockchain Farm” platform architecture. It is at the bottom and is embedded with real-time computing, big data processing, cognitive intelligence and other modules. In order to allow users to better understand the entire traceability history, data visualization innovation is also carried out based on big data.
⑧ What is sweeping the industry?
Answer: What is sweeping the industry? Information transmission: invisible technological assistance
Not long ago, the Ministry of Industry and Information Technology asked China Telecom and China Mobile , China Unicom and China Radio and Television issued 5G commercial licenses, marking China's entry into the first year of 5G commercial use. At the same time, blockchain technology is also accelerating innovation in the shipping industry.
A technological change It is destined to follow, especially for the shipping industry, which is undergoing profound changes. In the view of Luo Rongge, chief technology officer of Shanghai Wanxiang Blockchain Co., Ltd., the physical world and the digital world are completely different "two "World", the factors it contains should not be viewed from a traditional perspective. With the development of 5G, more things will be changed. "Artificial intelligence is to solve the problem of 'productivity', and blockchain technology is In solving the problem of 'production relations'. Blockchain technology can establish data sovereignty and multi-party trust mechanisms, making it difficult for data (or numbers) to be tampered with and making industry monopoly invisible. Appropriate application of this smart contract will make business relationships in the shipping industry more secure. It is simple and its cost of use is very low. The medium that communicates the physical world and the digital world is the Internet of Things technology in the 5G era. ”
Answer completed!
⑨ The future of the combination of shipping industry and blockchain
We are currently cooperating with a Yunliu blockchain company to solve the problem of paperless port , in my opinion, there are three things that are certain about the application of blockchain in the shipping industry:
1. Changes in the operating model of the shipping supply chain. The traditional operating model will change, and some institutional functions may also change. For example, freight forwarding-related institutions may transform into institutions that specialize in providing knowledge services and technical services. On the one hand, the decentralized operating model of the blockchain will not only bypass some intermediary institutions, but also simplify operating processes and improve operational efficiency. Save operating costs. On the other hand, payment activities based on the blockchain are programmable, that is, smart contracts. Using smart contracts, a large number of documents can be eliminated, and shipping can achieve paperless operations, thereby achieving cost savings. .Also through intelligentContracts and fund transfers between nodes have also become safe and efficient, and payments may be completed bypassing third-party institutions (such as banks).
2. Change the electronic data exchange system of ports and shipping. First, the blockchain will realize the exchange and application of electronic documents such as international trade bills of lading among all relevant entities in trade and transportation; second, the blockchain will realize the integration of the three streams of "logistics, information flow, and capital flow" in the international supply chain. And replace part of the logistics to form a stacking model of online trading channels. When problems arise during the transportation of goods, cargo owners, customs, carriers, and insurance companies can all trace reliable electronic evidence to clearly define the responsibilities of all parties and improve the efficiency of payment, delivery, and claims processing. In the future, various legal documents involved in international trade can also use blockchain solutions similar to bill of lading information exchange to achieve safe, reliable, and mutually recognized transmission
3. Change the credit evaluation system and innovate financial services. The use of blockchain should be meaningful for complex transaction scenarios involving multiple transaction entities. The most important thing in risk control is whether the transaction is authentic. Because the underlying data is open, it can solve the pain points of the supply chain finance industry. In the platform era, if the credit-related information of relevant transaction entities is stored on the blockchain and can be easily obtained, then transaction entities can directly conduct point-to-point trusted transactions, and the role of the intermediary is closer to that of a technical consultant. In fact, the current application of blockchain technology is indeed gradually transitioning from digital currency to "blockchain+", and gradually extending from the financial field to non-financial fields such as the Internet of Things. In addition, after the assetized shipping resources are put in digital form on the cloud through the blockchain, transactions and financing will be more flexible, and asset tracking and management will be more convenient.
