1. In what fields has the traceability service of Ant Blockchain been applied?

As far as I know, the application of Ant Chain in traceability started with Tmall International. During Tmall Double 11 in 2018, Ant blockchain technology traced the origin of 150 million products to ensure authenticity. Now Ant Chain traceability has also played a huge role in epidemic prevention and control. For example, "Zhejiang Cold Chain", a cold chain food traceability system based on Ant Blockchain and Alibaba Cloud, can realize products from the first stop of the supply chain to the consumption link. Closed-loop traceability management of minimal packaging to control the flow of the cold chain food supply chain.

2. How to apply blockchain

For blockchain and traditional IT and data technologies, I believe that the future development of blockchain technology must be "integration".

1) Traditional financial IT companies:

Blockchain technology can be quickly adopted by financial IT and insurance companies due to its outstanding technical characteristics of openness, transparency, uniqueness, safety and reliability. Applications in the IT field.

2) Traditional IT sharing companies:

The core capabilities of blockchain are mutual trust and sharing, so it is easy to be fully integrated with the concept of the sharing economy and then applied.

3) Traditional IT technology companies:

Blockchain will become part of the computer cloud services and big data of traditional IT companies. Nowadays, multinational IT companies are making great efforts in security and analysis, and all these services can be built on the basis of blockchain.

4) In addition, blockchain also has great complementary advantages in the field of AI companies. Blockchain is a new distributed database technology, so blockchain technology can solve problems in AI applications. Regarding the issue of data credibility, with blockchain technology, AI can focus more on algorithms.

However, I feel that blockchain technology is still in its infancy and needs time to be researched and verified. The final chance of defeating the enemy is always reserved for those who are prepared!

3. What are the applications of blockchain in the industry?

Take the tourism industry as an example. Blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, and credit consumption management. , tracking pilots’ professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumption points management are several application areas. In addition, with the development of blockchain, many related top domain names have been registered, which has had a relatively large impact on the domain name industry. In addition, blockchain also has applications in finance, games, entertainment and other fields.

(4) Extended reading on the application of blockchain in cold chain:

Blockchain is far more than just a technology, it involves What comes across is the spirit of “multi-party collaboration”. In modern society, many things must rely on everyone's cooperation to achieve the effect of 1+1>2, but in cooperation, we need to try our best to avoid problems such as "information asymmetry."

Therefore, alliance members jointly keep accounts, share data, and make everything public to eliminate "information asymmetry" to protect everyone's interests and allow the business environment to develop healthily. If you do things honestly, you will get the benefits you deserve. If you cheat, it will be known to everyone and criticized by thousands of people. Technology is the foundation that helps realize this model. This is the more important "district""Blockchain thinking".

5. What fields do these blockchain application companies mainly focus on?

There are many application scenarios for blockchain. The secretary will talk to you below. Let’s talk about several fields that are currently widely used:

(1) Blockchain + electronic invoice

In August this year, Shenzhen State Taxation Bureau and Tencent will jointly establish The country's first blockchain invoice jointly released by the laboratory management committee marks that the era of blockchain invoices has arrived.

(2) Blockchain + product traceability

Today In addition to Tmall, Cat's Double 11 once again dominated the world with a turnover of 213.5 billion yuan. Ant blockchain product traceability was applied to diamonds, imported milk powder, beauty cosmetics, health products, Wuchang rice, Moutai, etc. 150 million during the Double 11 period. This product has once again demonstrated to consumers the charm of the new technology blockchain. In addition to Tmall, JD.com’s cold chain also traces the origin of JD.com’s fresh food. Many e-commerce platforms have also begun to apply blockchain in the field of commodity traceability. Chain. Vaccine incident

(3) Blockchain + content
The first public chain - Ulord, users can build decentralized applications through this platform without third-party intervention. Digital media content sharing, Ushare, the world's first decentralized experience value sharing platform based on the Ulord public chain, has begun public testing. Ushare allows non-head users the opportunity to gain class promotion, eliminating the need for content middlemen. link. Through the mechanism of pricing contracts, tokens are distributed to everyone who forwards, likes, and reads, changing some of the current unreasonable interest patterns, making the entire mechanism more scientific, and the same content is distributed more widely.
( 4) Blockchain + Finance

Technology giant IBM officially launched a blockchain-based cross-border payment solution at the end of August 2018 - IBM Blockchain World Wire. Including HSBC European banking groups, including ), announced in July this year the completion of the first real-time blockchain-based cross-border financial transaction. In June 2018, Ant Financial announced the world’s “first” blockchain-based electronic wallet for cross-border remittances. The service was launched in Hong Kong, and the first remittance was completed on site.
(5) Blockchain + Insurance

The mutual insurance that has suddenly become popular in the past two days is the combination of insurance and blockchain The result of innovation. After eliminating the high threshold of traditional commercial insurance, Mutual Insurance adopts a 0-yuan way to purchase insurance and maintains fairness with the rule that one person gets sick and everyone shares it. Users can buy what they want and quit when they want, and the platform only charges some management fees. , which makes the concept of open and transparent distribution after decentralization of the blockchain come into full play. High transparency is achieved through blockchain technology, ensuring that there will be no insurance fraud or default.
(6) Area Blockchain + Intelligent Manufacturing

Alibaba, JD.com,IBM and other well-known domestic and foreign companies have begun to get involved in the blockchain + intelligent manufacturing business. IBM cooperated with Blue Ocean Camel to build a blockchain + foreign trade supply chain intelligent platform, Alibaba Cloud launched its own enterprise-level blockchain service BaaS (Blockchain as a Service), JD.com’s blockchain service platform Zhizhen Chain, etc.

(7) Blockchain + Medical

The main advantages of blockchain technology are decentralization, non-tamperability of information, and information transmission and sharing based on consensus mechanism. In all aspects, we can achieve the purpose of ensuring information security in various scenarios.

Overviewing the current development of blockchain technology and the characteristics of the medical field, we believe that the application of blockchain in the medical field can be mainly divided into the following four aspects: institutional medical information security and privacy protection; Personal medical information security and privacy protection, medical insurance and supply chain management.

6. New opportunities and challenges for blockchain enterprise applications

New opportunities and challenges for blockchain enterprise applications
New technologies come from the combination of existing technology modules. Once the power of the combination is superimposed, it will stimulate exponential growth in the economy. The economy is an expression of technological evolution.

Blockchain is actually a combination of several technologies, including peer-to-peer communication (P2P), distributed ledgers (also known as distributed storage), asymmetric encryption, etc. Once these technologies are combined, they will have a great impact on some new business models and economic forms, and these impacts are being revealed - now the world has entered an era called global automation, which is the fourth stage of our current informatization. stage.
We can call the Internet era that began in the 1990s and continues to the era represented by social media such as Facebook the pre-Internet era, that is, the first half of the Internet economy. The core of the rules in this first half is to improve productivity. Many technologies do not actually change the shape of enterprises and the economy. They achieve economic leaps by improving productivity. Now the new rules are called the era of automated global network economy. The core of the rules is to enhance connections and improve production relations, such as the sharing economy that has opened up a new business form. However, the current form of the sharing economy is still an economic model built with centralized Internet companies as the core. The current shared bicycles and Didi are a one-way economic model. In fact, they do not feed back the growth and improvement of value to users.
The global era of automation not only requires productivity-enhancing technologies such as artificial intelligence, blockchain edge computing, etc., but more importantly, it requires a new model to improve production relations. Blockchain is actually such a new technology that can bring a new shift in business models to everyone.
So the future is here. The current eight core technologies include blockchain, Internet of Things, augmented reality, virtual reality, artificial intelligence, robots, drones, 3D printing, etc., of which onlyBlockchain is a technology that improves production relations and enhances connections.
Microsoft believes that technologies such as mixed reality, artificial intelligence and quantum computing are revolutionary new technologies that will continue to improve productivity in the future. But in fact, blockchain is not a new technology. It is just a combination of existing technologies. Its value lies in creating a trustworthy platform. As Alan Weber, founder of Fast Company, said: The new economy starts with technology and ends with trust.
In November 2015, the cover of The Economist magazine was called trustmachine, which is the machine of trust, the promise of blockchain. In fact, it is announced from this perspective: Blockchain technology is actually the core technology of the future Internet 3.0. This technology will gradually be transmitted to many aspects of the entire social and economic life through upper-layer applications, providing support for many business models, industry operations and governance systems. Bring innovation. Blockchain builds a new type of Internet with value as the core, rather than the old generation Internet with information as the core.
2 Blockchain+ vs. Internet+
Blockchain integrates trust mechanisms and technology and will bring great changes to the world.
In the Web 1.0 era before 2005, e-commerce portal entrepreneurs basically used a large portal to start their business in a one-to-many manner.
The Web 2.0 era is the era of social networks and sharing economy, but in this ecosystem, core enterprises are still centralized, monopolizing user relationships and large amounts of data, enjoying the value of user contributions, and being able to decide rules at will. In this case, the so-called Internet + is an information model that is harmful to traditional enterprises.
The Web 3.0 era is a new global sharing economy based on the blockchain value network. It is decentralized, so there will be no oligarchic monopoly on innovation, interactions will be more spontaneous, and the scope of collaboration will be wider. Extensive, the impact will be more comprehensive and deeper.
Therefore, the best way to digitally transform and upgrade traditional enterprises or industries is not Internet+, but Blockchain+. Because Internet+ still needs to rely on a centralized, classical Internet enterprise. Although companies like Alibaba, Tencent, JD.com, and Xiaomi are now at their peak, they are still essentially centralized enterprises. They formulate the rules of the game in the ecosystem and monopolize customer relationships and data.
We call blockchain+ web3.0, which actually has a higher dimension than traditional Internet companies and Internet ecological companies. When information was scarce in the past, it was necessary to build a hierarchical structure and center to improve the overall information transmission efficiency. But when there is enough information, the network of peer-to-peer relationships (P2P) will gradually replace it, and when these networks of peer-to-peer relationships are connected together, a high-dimensional additive value network can be formed. . We call enterprises that rely on this kind of network system a commonAn enterprise that understands economic socialization.
The high-dimensional business model of blockchain+ has a stronger future-oriented imagination than the existing Internet ecosystem or companies such as Internet+ enterprises. Let’s review most traditional companies: one-dimensional companies are engaged in engineering, and their main business models are actually rent-seeking, resource monopoly, and customer relations; two-dimensional product companies have certain product development and marketing capabilities, but this Both are company forms in the industrial economy era. Its value curve is linear. If you invest one, you will get one, and if you invest ten, you will get ten. Therefore, a company like Jack Ma with a market value of hundreds of billions of dollars actually conforms to the traditional neoclassical economic growth pattern due to so many years of accumulation, and its marginal returns are diminishing.
At Sanwei Internet Service Company, due to the addition of online service dimensions, data value-added services began to be provided. Its core is low-cost customer coverage, which reduces the service cost to customers, so its adaptability can be higher than In two dimensions, the price-to-earnings ratio of a company in this form can be as high as more than twenty times. The third-dimensional company can further open up the API and allow third parties to develop more applications on its platform. At the same time, it can connect service providers and users to form an online market. This constitutes a platform company. Platform The company's price-to-earnings ratio can exceed forty times.
When platform companies further open up their capabilities, combine resources such as data network brands and users with investment services, and empower partners, they will become Internet ecological enterprises like BAT. This ecosystem The price-to-earnings ratio of Internet companies in a centralized cluster may even exceed 100 times.
This is why these companies are desperately advocating Internet +. In fact, Internet+ does not create new value for traditional companies. It just uses the method of attracting stars to attract all the data, customer relationship channels, etc. of traditional companies to Internet ecological companies. They only play a subversive role in traditional enterprises, but they do not create greater value for society. They are still a value ecosystem with their own enterprises as the core.
Everyone has contributed to Jack Ma’s company for so many years, and has continuously contributed so many transactions and data to support his corporate price-earnings ratio. If you think this is not a particularly fair way, then we now have a new business model, which is blockchain. Through the blockchain + industry, an alliance ecosystem is formed, that is, the alliance chain. Even if it does not issue coins, it can have a higher dimension than existing Internet companies, because it is a cross-organization and cross-platform industry-oriented business processes, a secure distributed sharing, which will completely subvert the traditional enterprise ownership model.
The blockchain uses consensus mechanisms and beliefs to connect enterprises, which forms an industry chain, a decentralized social enterprise owned by the whole people, and can embed trust and security mechanisms without the need for a third party. In the autonomous agreement of the entire industry chain, the data of all relevant parties will be respected and protected on the chain. At the same time, if we can add C-side users in the future,Come in, and then through digital currencies, certificates or tokens, you can add new business model dimensions and open up greater value space. That is to say, all businesses are combined with B2C business to form an industry palace for all employees.
This is what we call the bright future of the business model that blockchain 3.0 brings to everyone. It is completely based on a decentralized high-dimensional value network. I have listed for you some entrepreneurial project companies in this field, whether in distributed cloud storage, decentralized secure social networking, distributed identity management, distributed copyright and digital asset management, Internet of Things smart contracts, public governance There are many 3.0 creative innovation companies in fields such as anti-counterfeiting and anti-fraud, and digital market transaction prediction.
Three Opportunities and Challenges of Blockchain
Most of the projects currently implemented are relatively easy to combine finance and digital asset management due to the inherent properties of blockchain technology. However, in fact, we have also seen that traditional industries are also becoming more and more popular. There are more and more new opportunities to combine blockchain. This market will reach 176 billion US dollars by 2025, and will reach 3.1 trillion US dollars by 2030. This is actually a very, very huge number.
There are actually many strange entrepreneurial projects in China, but now the government has imposed some restrictions last year. However, in the future, the government will have some new compliance requirements for digital currencies, and will gradually relax restrictions on blockchain infrastructure.
2018 is a very critical year for enterprises to go online. This is equivalent to 20 years ago when you talked to companies about enterprise internet. It sounded like a fantasy and they didn’t know how to start. But those who started exploring the Internet for enterprises early were precisely the group of pioneers from around 1997 to 2000. They eventually became the trendsetters of the previous generation of classical Internet. Therefore, 2018 is a very critical opportunity for traditional enterprises.
The main application scenarios of blockchain + are actually nothing more than several areas based on the core technology of blockchain, such as digital identity management, digital asset management, development and deployment of distributed applications, and the development and deployment of smart contracts. Services, these four main application scenarios combine some characteristics of the industry to provide enterprises with application implementation services.
Four Theoretical Pioneers of Blockchain
So enterprises need to fully refresh their understanding and upgrade the underlying commercial operating system in this round of opportunities. There are some disruptive innovations here, giving traditional industries and the public the opportunity to counterattack the classical Internet. I have listed a few books here. If you have time, you can read them and have a deeper understanding of blockchain. Although some of these books were written in the 1930s and 1970s, classics always have guiding significance.

The most famous is Schumpeter's theory of economic development. He believed that innovation is the fundamental cause of economic development.
Then Thomas Kuhn proposed that the technological paradigm revolution is not continuous. At a certain stage, it will cause a new revolution. When the revolution comes, many traditional enterprises will die., but at the same time, the business models and economic forms established by new technologies will explode.
Christensen’s main contribution is of great significance to how traditional enterprises can seize opportunities, avoid the innovator’s dilemma, and embrace new opportunities to achieve transformation and innovation.
The British management guru, Charles Handy, his current book is called "The Second Curve", which mainly talks about how traditional enterprises can achieve leapfrog and transformation with the help of technological innovation and business model innovation.
5 Crossing the Second Curve

In terms of crossing the second curve, Microsoft’s own experience and lessons are actually worth learning from. Everyone knows that Microsoft was the overlord of the PC era. At that time, 76% of the industry's profits were divided between Microsoft and Intel. However, it also fell into the innovator's dilemma. It was the success of the PC that caused Microsoft to miss out on the mobile Internet. The opportunity has allowed companies such as Apple to overtake it, but Microsoft has not missed the opportunity of cloud computing. Microsoft's early layout in AI has given Microsoft a great lead in the world's smart cloud and blockchain. These experiences and lessons can be summarized to help traditional enterprises achieve digital transformation.
Microsoft has seized opportunities in artificial intelligence-led cloud computing, blockchain IoT edge computing, and mixed reality. The second curve has been achieved, and Microsoft will have some new layouts in the future, such as quantum computing, etc., which are some of Microsoft's own successful experiences. Of course, there are some lessons from failure. In terms of mobile Internet, Microsoft also acquired Nokia. In fact, Nokia is not worth acquiring at all, because Nokia has not crossed from the first curve to the second curve. In terms of mobile Internet, Nokia will be ignored by outsiders. Companies that have never done mobile Internet are easily defeated.
This kind of digital transformation of the enterprise industry, or the conversion of old and new kinetic energy, mainly helps traditional enterprises connect with external entrepreneurs, incubate entrepreneurial projects through propositions, and achieve transformation and innovation. Therefore, a new type of enterprise outsourcing innovation is needed. Incubation method. Because if the company does its own incubation, it will still be tied to the business trajectory of the first curve, so it can only be incremental innovation to improve the efficiency of existing products or services. For the second innovation, it needs to allow a certain space for trial and error, so it needs to use new methodologies to guide disruptive innovation.
It needs to be oriented towards value creation and growth, and cannot be tied to the current core business, because once tied to the current core business, all performance appraisal management mechanisms will fall into excessive path dependence, resulting in lock-in. In this case, it will not be able to jump out of the original business boundaries and will not be able to see changes in the external market. This is also the reason for Nokia's failure. Nokia strives for excellence in traditional mobile phones, and its management efficiency is very good. So when it was acquired by Microsoft, Nokia didn't know how it lost.
Nokia’s failure was actually due to its failure to see that subversion may not necessarily come from within your industry, but may also be an invasion from the outside.By. That is to say, as said in "The Three-Body Problem": If I destroy you, it actually has nothing to do with you.
The second curve plan is to prevent traditional enterprises from falling into their own business development trajectories, so enterprises need transformation and customized accelerators to help them develop new business directions. And this requires a mechanism to guarantee, because the original internal incubation of enterprises comes from the internal organizational structure process, so we must use external incubation methods to directly recruit outside entrepreneurs to supplement fresh blood, and then achieve transformation and innovation through hybridization, and more importantly Focus on external markets and partners.
This will give entrepreneurs a great degree of freedom, and then encourage them with a high risk-reward ratio through the setting of company equity. As an enabler, the enterprise will provide business resources and start-up funds, but do not interfere too much in entrepreneurial projects. own operations and development. All companies need to do is observe, give feedback, and wait. If such a project can be hatched, it will be a great impetus for expanding corporate boundaries and activating corporate ecology.
Six application scenarios of blockchain
The following is a brief introduction to several blockchain application scenarios:

The first is blockchain + cross-border trade financial services. In fact, this involves many solutions, including exporters, importers, issuing banks, issuing letters of credit (LoC), etc. These actually require a mechanism to securely share data across agencies, organizations, and platforms. , and blockchain can just guarantee the realization of the solution. And through smart contract automation, when various conditions are met, clearing and settlement payments can be completed automatically without manual participation.
Cross-border trade finance involves many parties. If we follow the existing method, each party has its own system and some procedures need to be carried out repeatedly. Reconciliation needs to be confirmed by email and fax. It can take three to five weeks to complete a trade finance deal.
Now through the blockchain, all parties in trade finance can share the data on the ledger, and the member units of the alliance chain can be updated synchronously. The use of smart contracts can realize automatic and synchronous execution of multiple parties, so that end-to-end The end-end business process is shortened from three to five weeks to two or three days, and operations that originally required repeated confirmation can be greatly simplified. It only takes about 5 steps to achieve a closed loop of trade finance.

Blockchain can also be used to improve medical and health services. Patients have certain rights to decide who to share their medical history and other information with, to what extent, for how long, etc. Blockchain can effectively solve problems that traditional, decentralized medical drug R&D, physical examinations and other institutional systems cannot solve. This requires the establishment of a personal health data bank.

Blockchain can also be used for cold chain logistics and end-to-end food safety traceability services. From the origin of food to slaughtering, processing, and transportation, all data parameters can be uploaded to the chain, which will provide an end-to-end security guarantee.
Here is an exampleFor example, this salmon in Norway is doing food safety traceability through a blockchain company, and in this process, because the data of all parties are on the chain, it can then be triggered according to events through self-service smart contracts. Realize payment and settlement of supply chain finance, which greatly improves the efficiency of the entire supply chain.

Blockchain can also provide services in the education and employment markets. School research institutions, examination institutions, employers, and government departments can safely share students’ academic qualifications, certificates, papers and other data.

The most important thing is that blockchain can also realize P2P peer-to-peer, microgrid power trading or energy trading services. For example, during the renovation of the old city in Brooklyn, photovoltaic solar panels were added to the roofs of houses to generate electricity. The electricity generated is not sold to power energy companies, but is made into a microgrid in the community and then traded through virtual currency.
This model can be further expanded, and the solar energy produced on the roof can be further used as a distributed charging pile, and then internal household electricity, security electricity, smart door locks, etc. can be uploaded to this blockchain. Provide overall shared services.

7. How blockchain is applied to the food chain

Summary

Chefs can make sure their food is sustainably sourced and organic through blockchain technology. How to make sure of that? IBM thinks the solution lies in Blockchain. IBM is connecting all players in the global supply chain from farmers, procers, suppliers, manufactures in a secure shared platform---blockchain.

Blockchain is a decentralized ledger where activities throughout the whole food supply chain are recorded, verified, and become immutable at each step. This technology applies to any numbers of vegetables from fresh to packaged.

It has three advantages:

Consumers can scan the code on the package to check where the food comes from and whether it is genuinely fresh etc.

It can remove the distributor in the middle.

Traceablity (one of the functions of blockchain) can help spot the problematic food instead of decimating the whole farm in case of a food-born outbreak

Blockchain is a decentralized distributed ledger. All transaction data on the entire chain can be recorded and authenticated in the ledger and turned into tamper-proof evidence. The application of blockchain in the field of food supply has three major advantages:

1. Because every step of food from farm to table is recorded on the ledger, the information is traceable. Consumers can obtain the source information of food by scanning the code.

2. Because every step of the transaction and information is open and transparent, trust in the supply chain is increased, and the middle agent between the farmer and the purchaser can be eliminated.

3. Because the information is traceable, if a certain food causes mass poisoning/disease spread, the problem food can be accurately found and the accidental killing of other healthy foods can be reduced.

8. What are the benefits of blockchain + supply chain in industry applications?

The application prospects of blockchain in the Internet of Things and logistics fields Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.
Skuchain has created a new supply chain solution based on blockchain to synchronize commodity flow and capital flow while mitigating the problem of counterfeit goods. Provenance, a London-based blockchain start-up, provides supply chain traceability services to enterprises. By recording the entire process information of the retail supply chain on the blockchain, it can achieve the retrieval and tracking of product materials, raw materials and product origin and history information. , improve the transparency and authenticity of information in the supply chain. A German start-up company Slock.it has made a smart lock based on blockchain technology, connecting the lock to the Internet and controlling it through smart contracts on the blockchain. Simply transfer money to the smart contract account through the blockchain network to open the smart lock. When used in hotels, guests can open the door easily. This is the real sharing economy!
Not only in supply chain management, but also in the financial field, intelligent manufacturing, culture and entertainment, financial services, medical health, and IP copyright , education, sharing economy, communications, social management, charity, social employment, and e-government can all be widely used.
At present, domestic Internet and IT are involved in the blockchain industry, and are beginning to develop or launch a series of solutions for basic application cases. In the current development trend, blockchain technology is integrated into smart life, Internet of Things and other fields, integrating massive physical business application scenarios, and conducting blockchain+Entity industry projects, realizing the physical transformation and upgrading of the entity industry, are one of the most representative blockchain application directions.
