⑴ How is blockchain technology only used in logistics?

How will blockchain technology affect supply chain and logistics?

If blockchain Chain technology allows us to track all types of transactions more securely and transparently, imagine the possibilities it presents throughout the supply chain. Whenever a product changes hands, the transaction can be recorded, creating a permanent history of the product from manufacturing to sale. This can significantly reduce time delays, increased costs, and human errors that plague today’s transactions.

Some supply chains are already using this technology, and AntZhilian believes that blockchain may soon become a universal "supply chain operating system" (Spend Matters).
Consider how this technology could improve the following tasks:

1) Record the quantity and transfer of assets like pallets, trailers, containers, etc. - as they move between supply chain nodes.

2) Track purchase orders, change orders, receipts, shipping notices or other trade-related documents.

3) Assign or verify the certification or certain characteristics of physical products; such as determining whether the food source (Provenance) is organic or fair trade.

4) Link physical goods to digital tags such as serial numbers, barcodes, and RFID.

5) Share information about manufacturing processes, assembly, delivery and product maintenance with suppliers and customers.

Regardless of application, blockchain offers shippers the following advantages:

1) Enhanced transparency. Documenting a product’s journey throughout the supply chain, revealing its true origins and handoff points, increases trust and helps eliminate issues that arise in today’s opaque supply chains. Manufacturers can also reduce recalls by sharing logs with OEMs and regulatory agencies.

2) Higher scalability. Virtually any number of touchpoints can be visited.

3) More secure. A shared, indelible ledger with codified rules may eliminate the need for audits of internal systems and processes (expense matters).

4) Increase innovation. As a result of decentralized architecture, a wealth of opportunities may arise in new industries created by technology.

⑵ Application cases of blockchain + IoT convergence technology in the shipping field

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 fully competitive.Opening the market involves 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 use capital to effectively serve 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 shipping investment team with more than 20 years of rich experience in international shipping. 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 IMC Shipping. Team members are very familiar with the shipping market and financial market. They are not only good at ship operation, but also He specializes in ship buying and selling 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, an annual turnover of more than 100 million US dollars, and an average annual investment of The income reaches 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. By uploading AIS data to the chain, we can grasp the real-time location information and navigation trajectory of each ship;

2. By uploading the charter contract to the chain, investors can understand the operating income;

3. Let investors understand the operating profits by uploading voyage benefit calculation data to the chain.

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. Compare the cargo capacity calculated by collecting ship draft data through sensors with the quantity agreed in the transportation contract.

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 investors and financial institutions receive their investment returns in a timely manner.

In addition to the authenticity of information disclosure and 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 been basically maintained at about 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 the fixed cost, it 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 an investment of US$5 million, after deducting depreciation, can still recover the investment in three years.

By integrating blockchain technology and IoT technology, the Haifu team will effectively promote the rapid development of the industry by applying it to the shipping industry. and standardize development, eliminating the complicated procedures of due diligence of financial institutions, greatly reducing the investigation threshold for investors or financial institutions, establishing technical barriers to credit, and bringing stable and reliable investment returns to investors.

⑶ How blockchain technology can play a greater role in economic and social development

As the construction of a transportation power continues

In September 2019, the Central Committee of the Communist Party of China and the State Council The "Outline for Building a Powerful Transportation Nation" was issued, and it is planned to basically build a strong transportation country by 2035. In the "Outline for Building a Powerful Transportation Nation", in addition to "reducing costs and increasing efficiency" in my country's transportation based on existing infrastructure, advanced transportation equipment plays an "innovative" role, mainly transforming the incremental growth of my country's transportation. In the "Outline for Building a Powerful Transportation Nation", advanced equipment mainly includes large-scale carriers and special equipment to promote the upgrading of equipment technology; research and development of autonomous driving, vehicle-road collaboration, underwater robots, large-scale deep-sea multi-functional rescue ships, etc.; and the widespread use of smart high-speed rail , smart roads, smart shipping, etc.

⑷ When will blockchain technology come to us?

It is generally difficult to predict time.

But blockchain is special. In fact, this technology has already begun to be used, but we can’t feel it in our daily lives. For example, IBM's blockchain platform has begun to be used in the shipping industry to help handle complex contracts. Although it is not directly used as a monetary payment tool, it has actually improved the operation methods of subdivided industries. I don’t know if it can be considered as approaching us.

Blockchain has actually been integrated into our lives for a long time, but we have not realized it. Many people think that blockchain technology is unfathomable, but in fact, what can be widely used by ordinary people is the distributed accounting system. Using such an accounting system can truly record every detail of our lives. If the whole people gather together In a unified accounting system, our consumption behavior as consumers will be recorded one by one and summarized. If enterprises and merchants can obtain the big data of this record, they can order production on demand and reduce or even eliminate duplication of construction. , no more wasting resources. Teacher Gao Jinbo's book "Smart Society" gives such a roadmap. The innovatively designed public network ecosystem is the application of blockchain technology. Currently, the cloud wallet, cloud warehouse, and youtime are online. Download it from various mobile app stores and experience it, I believe it will change your perception.

Blockchain technology has actually entered our lives, but the application level is less. Let me give a few examples below.

1Walmart uses blockchain technology to Agricultural products sold are tracked by industry to shortenIt shortens the traceability of agricultural products and improves the safety of agricultural products.

2 Ant Blockchain uses blockchain technology to make public and transparent announcements about charity, so that every donation can be used for what it can. Place,

3 Taobao’s overseas shopping also uses blockchain technology to trace products,

4 The government uses blockchain technology for office work,

5 There are also blockchain invoices, etc.

In the future, there will be more industries integrating with blockchain technology,

Hello, before I know it , the blockchain has been born for 11 years. In fact, the blockchain is already entering our lives.

First of all, we need to know that the biggest feature of blockchain is: traceability and non-tampering! According to this characteristic, blockchain technology has actually entered our lives, affecting our daily necessities of life!

Here are a few examples:

In 2019, Shenzhen issued the country’s first blockchain tax invoice! In the same year, Guangdong issued its first blockchain subway ticket! On April 1, 2020, Yunnan Province issued the first blockchain electronic invoice in the field of public transportation! On April 9 of the same month, Shenzhen Evergrande Real Estate issued the country’s first real estate sales blockchain idea invoice! It is worth noting. This is the 18 millionth invoice from the Shenzhen Municipal Government, covering hundreds of industries such as finance, insurance, public transportation, catering retail, and Internet services!

In Tmall Supermarket, if you buy some high-end liquors such as Moutai and Wuliangye, there are also anti-counterfeiting traceability codes made with blockchain technology!

In 2019, the country regards blockchain as a national strategy to develop and support. I believe that blockchain will penetrate into more industries and serve us in the future!

Blockchain technology is already here!

Human society currently has three economies: the real economy, where labor creates value; the virtual economy, where transactions create value; and the blockchain represents the digital economy, where users create value. This is a three-dimensional value system. Therefore, the real economy looks at labor, the virtual economy looks at transactions, and the digital economy looks at users.

When we understand that users create value, data becomes resources, and numbers become assets, we can understand that the new economy is the blockchain economy.

Based on different resource systems, there will be different living spaces. Basic resources are the foundation. The higher the dimension of the market space, the greater the space for wealth. The real economy is like land, the virtual economy is like ocean, and the digital economy is in space.

Never think that the new economy is something that others have not done before. As long as any industry upgrades to this space, it is a new economy. As long as the current business canIf we are able to break away from our dependence on land, oil, coal and minerals, and on stupidity, we will see that an infinite space of "people-oriented" is opening up.

We have gradually bid farewell to the era of "valuing rare things" and are moving towards the era of "respecting nature and respecting people".

What mankind will face in the future is a new "human society": using the Internet as "physical power", artificial intelligence as "intelligence", and blockchain as "computing power". Specifically, the Internet transmits information, intelligently processes data, and blockchain trades assets. They constitute the three cornerstones of the digital economy and serve as conditions for each other, jointly changing the competitive landscape of society and creating a high-dimensional space for wealth.

Blockchain is a ledger that can never be tampered with and has been used in some fields. Blockchain is also a battleground for international military strategists. Do you think it is important?

In 2008, the subprime debt crisis broke out in the United States. Wall Street's behavior is too ugly, and it has been exposed by the Internet in front of the eyes of all mankind.

Americans are angry. Some people condemn Wall Street's greed, some people occupy Wall Street, and some people begin to try to find an alternative to Wall Street's accounting system through the practice of distributed accounting technology.

Therefore, first of all, we have to be clear: First, the purpose of blockchain, a concept that was later summarized, is to replace the traditional accounting path.

Second, blockchain is a means, and the purpose is to break Wall Street’s monopoly on finance, improve financial efficiency, and reduce the costs of physical enterprises through universal accounting rights.

After understanding the above two logics, let’s look for the problem:

What is its root cause? This is the focus of our research. If we don't understand this problem, we won't be able to reach the forefront of this field.

In fact, it has already appeared in our lives. There are many cases in China at present, but it is not popular enough. In less than 5 years, there will be a large number of application cases!

Blockchain invoices/ipfs protocol/ant energy, etc., are all very good cases

Blockchain is a ledger - cannot be modified or filtered out - has been used - For example, transfer - credit - traceability - certification - you just don't know

Blockchain originated in the West. The application of Bitcoin is one. It is a peer-to-peer cash payment system. Our country’s blockchain technology is relatively complete, and its application is only a matter of time.

⑸ What is sweeping the industry?

Answer: What is sweeping the industry - information transmission: invisible technological assistance

Not long ago, industry and informatization The Ministry of Finance issued 5G commercial licenses to China Telecom, China Mobile, China Unicom and China Radio and Television, marking theChina has entered the first year of 5G commercial use. At the same time, blockchain technology is also accelerating innovation in the shipping industry.

A technological change is bound to follow, especially for the shipping industry, which is undergoing profound changes. According to Luo Rongge, chief technology officer of Shanghai Wanxiang Blockchain Co., Ltd., the physical world and the digital world are completely different "two worlds", and the factors involved should not be viewed from a traditional perspective. With the development of 5G , more things will be changed. "Artificial intelligence solves the problem of 'productivity', while blockchain technology solves 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 , making industry monopoly invisible. Appropriate application of this smart contract will make business relationships in the shipping industry simpler, and its use cost is also very low. The medium that communicates the physical world and the digital world is the 5G era. Internet of Things technology."
Answer completed!

⑹ 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 a sequential manner 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. Suppose there is a distributed data record book. This record book only allows additions, deletions and changes. Its structure is composed of individual data records. "Blocks" are connected in series to form a linear chain (thisThis is also the origin 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 finalize the selected block. block reached consensus.

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 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 blockchain technology and has exclusive write permission to the blockchain, and the information is not made public. The current conservative giant(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 blockchain to storeStore the hash value 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 financial business: reduce human intervention, reduce costs and operational risks

Point-to-point value transfer, physical bills or central system for control and verification; intermediary will be eliminated and human intervention reduced. Improve efficiencyrise, financing channels will be smoother, risks will be lower, and many parties will benefit.

(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.

Logistics Integrity System Wagonbang Wagonbang launched a blockchain-based financial solution for logistics enterprises, aiming to provide enterprises with reliable financial services. It can not only help drivers solve the problem of loan difficulty, but also change the current situation of lack of integrity in the industry and help build a logistics integrity system. Help build the identity chain of logistics companies and create a trusted data ecosystem for logistics companies. Using a transparent, supervisory, and traceable algorithm model, we screen reliable companies that need financial support and provide them with financial services. On the other hand, at the technical level, various law enforcement departments are linked to jointly punish dishonest companies.

6. Government management

(1) Election

Based on the characteristics of blockchain technology and considering the shortcomings of current election technology, we will build an open source , Blockchain applications for elections, voting and lotteries, we call it the ElectionChain. We hope to optimize election and voting technology to make voting more open and transparent, reduce human manipulation, and allow voters to verify their election results.

Including identity authentication, multi-chain system, flash investment protocol, consensus algorithm EDPOS, privacy protection, voting mechanism design, decentralized ELC rental market, storage solutions, smart contracts, etc.

(2) Government services

Aiming to realize an e-government digital ecosystem based on blockchain technology and provide citizens with government services and an automated mechanism for the business of various government departments, it must be All areas of national government affairs are combined to form a common information space, including government agencies, economic data, financial transactions and social fields. This ecosystem should also include registries and corresponding software for building smart contract-based applications and platforms for government agencies, businesses and public users.

⑺ 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 the one that has been favored in the past two years is Logistics field, 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, 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 online dispatch of fleets. Single issue.

⑻ What is the relationship between shipping and blockchain?

The combination of blockchain and shipping industry is mainly reflected in the accumulation of enterprise transaction operation data through shipping blockchain to form a large Database, and then create a full-process automatic blockchain system, completely opening up all aspects of the platform and forming an information sharing channel. I heard that ChainNova is doing this, but I don’t know if there is any cooperation.

⑼ What are the application examples of blockchain technology

The express logistics industry is an industry that is very suitable for the application of blockchain technology.

In fact, the logistics ecosystem is relatively complex and there are many groups involved in the process.

The industry itself is a complex of segments with the concept of "flow". Starting from the initial "business flow", it gradually gave birth to "logistics", as well as the corresponding support of "capital flow" and "information flow" , complete the service chain.

There is a key issue behind the emergence of various "flows", which is the transfer of commodity ownership.

Coincidentally, many of the types of problems solved by blockchain technology are related to the trust friction generated during the transfer of asset ownership.

The application of blockchain technology can significantly improve the processing speed and efficiency of settlement business in the express logistics industry, effectively solve the problem of traceability and anti-counterfeiting of items, and fully ensure information security and the privacy of senders and recipients.

In the field of promoting application in the express logistics industry, there are domestic blockchain companies doing applications in this area, such as Walton Chain.

Last year, Waltonchain reached a strategic cooperation with Huodou (Xiamen) Technology Co., Ltd., using Waltonchain’s “RFID blockchain” technology solution to help it improve its logistics solutions and move goods to Dou puts data on the chain in all aspects of its logistics turnover, such as entering and exiting the warehouse, receiving goods and other key nodes. After deploying the reading and writing system, when the object passes through any link, the relevant data can be read by the RFID reader and writer, and the relevant data can be read by the RFID reader. The corresponding behavior is converted into data and uploaded to the blockchain. Users can trace the entire logistics process with one click.

Four business scenarios that can be implemented in the real environment are suitable for the application of blockchain technology.

Scenario 1: Insured express delivery

Revolving around the insured scenario, express companies transport goods, insurance companies provide guaranteed goods, merchants provide goods sales, sellers purchase insured services, and the government regulates the industry.

So, what should be recorded on the blockchain? There are several key points. The logistics details of the goods, accounts, identities, claims, other reference data and other information are recorded on the blockchain.

Insured price is the concept of a contract. When the customer signs for the package normally, the account claim is automatically triggered, the contract ends normally, and the premium is automatically cleared. If there is a problem or missing piece, the insurance company's claim process will be triggered.

Scenario 2: Charity express delivery

For charity activities, such as the "One Cent" campaign, one cent from the cost of each charity package is donated to the account of the charity organization . In this scenario, the express delivery company is still responsible for the transportation of goods, the public welfare organization provides the execution of public welfare activities, and the poverty alleviation merchants provide the sales of public welfare and poverty alleviation products.

Then what is recorded in the blockchain is the logistics details of the goods. After the package is signed for, it will be recorded on the blockchain, automatically triggering the transfer from the logistics company's public welfare account to the public welfare organization's account. When the public welfare activities are completed, the entire process is open and transparent, which avoids the public's distrust of social welfare activities.

Scenario 3: Industry blacklist sharing

At present, the blacklist of express delivery employees is still mainly offline. We hope that through blockchain technology, each company can record the blacklist of employees on the blockchain, and other companies can also query it, and the data cannot be modified, and can be traced back to which company this person worked in What kind of inappropriate behavior and other information.

Scenario 4: Supervision of safety incidents in postal delivery channels

Many express companies will install security inspection machines, and the government also wants to know whether each logistics company has any transportation safety hazards. Through the distributed accounting model, each express delivery company can record the effective information of the security incident on the blockchain when a security incident occurs, so that regulatory agencies can monitor it in real time and cannot be tampered with.

⑽ The relationship between shipping and blockchain

The core appeal of the “Blockchain Farm” projectIt is to ensure the quality of production, achieve fast and convenient circulation and increase the real income of farmers. 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 realizes the true traceability of goods, but also increases the output of the blockchain farm 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.
"At present, the project has completed the first phase of research and development. Within this year, it will use blockchain technology to track the origin and deliver the first batch of large-scale farm assured food to consumers. In the process of building a blockchain-based large farm, how How to upload data collected by massive IoT devices to the chain, how to integrate blockchain technology with the current mature technology system and provide the same high service quality, how to technically ensure consistency between online and offline, and how to achieve seamless process throughout the entire process. Dead ends and so on are the key points of project innovation." Dong Ning, CEO of ChainNova, said.
In order to cope with these challenges, ChainNova designed the "Blockchain Farm" platform infrastructure. Blockchain technology is at the bottom of the entire "Blockchain Farm" platform architecture, and it also embeds 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 has also been carried out based on big data.
