Ⅰ Jiang Bing, Chairman of State Grid Electric Vehicle Company: Blockchain technology promotes mobile energy Internet

January 11-13, China Electric Vehicles 100 Forum (2019 ) was held at Diaoyutai State Guesthouse in Beijing. Jiang Bing, Chairman of State Grid Electric Vehicle Company, delivered a keynote speech. The content of the speech is as follows:

Dear host, distinguished guests, I am State Grid Electric Vehicle Service Co., Ltd. Chairman Jiang Bing.

State Grid Electric Vehicle Company is the specialized electric vehicle segment of State Grid Corporation of China. It currently operates the world's largest charging network and owns the world's largest Internet of Vehicles platform. The theme of this 100-person meeting is "Transportation, Energy and Cities". I would like to talk about our experience of the next development trend of electric vehicles and energy based on our work.

First, the era of electrification of transportation.

We believe that the development of electric vehicles has entered a new development period and has launched the comprehensive electrification of transportation. We can all see that the development of electric vehicles increasingly reflects its energy attributes. It is not just a means of transportation, which was fully explained in Chairman Chen Qingtai’s speech yesterday. Let me share some insights based on our work.

This is an analysis of the strategic direction of transportation electrification from an energy perspective. The above picture is the entire life cycle flow chart of our electric vehicles, which was made by Tsinghua University. We can see that in the entire energy life cycle process, about 30% of the entire energy becomes power, and finally it is utilized. This is the entire synergy effect. In terms of power generation, we are talking about coal. The picture below shows the current efficiency of high-performance automobile fuel engines, from oil to gasoline to power. According to the most advanced technology, it is only 15%, so its system efficiency is only half that of electrification. Therefore, from the perspective of energy revolution, the electrification of transportation is a historical necessity. When we compare electric vehicles and gasoline vehicles, we cannot compare them purely from an economic point of view, because these are different things. From the perspective of energy efficiency, it is a revolution and a change. Therefore, we believe that the electrification of transportation is a common development trend of the transportation revolution and the energy revolution.

There was a historic moment last year. In November last year, the production and sales of new energy vehicles in China exceeded 1 million. At the same time, for the first time in history, the consumption of fuel vehicles stopped growing and fell in November. 13%. Everyone knows this number. November 2018 is a historic moment, a moment when the growth of fuel vehicles stopped, and a turning point in the century-old history of human automobile development. Don’t underestimate November 2018. This is a historic moment.

These are trucks, more than 800 of them, burning diesel. Once the trucks are on the road, the blow to fuel-powered vehicles will be devastating.of. Why do you say that? Mr. Yang Lei is in the oil business. In our current refining industry, diesel and gasoline have a fixed ratio. Diesel is the power for ships and trucks. If no one uses diesel, gasoline cannot be produced. This has nothing to do with price. , so the truck is of great significance.

A new trend in transportation electrification is port shore power. Now inland rivers and along the Yangtze River, ports have been gradually converting to shore power. This is the shore power of the Yangtze River Three Gorges ship lock built by the State Grid Corporation in November last year. , has been put into trial operation. This is the largest shore power project in the world.

This is a cargo ship launched by the Guangzhou Shipping Bureau. This is a passenger ship manufactured in Taizhou, Jiangsu. It will be delivered in February this year. It is the first time that electric power has appeared as a passenger ship on the Yangtze River. The whole thing has 2200 kilowatt-hours of electricity and can last 120 kilometers on a single charge. After its passenger and freight transportation becomes electric for small tonnage, its technology will rapidly develop to large tonnage, and will further develop to coastal freighters and offshore freighters. As long as the next port can be found within 200 kilometers, it can be electrified. The freighter burns heavy oil, and the refining is gasoline, diesel and heavy oil. If no one uses diesel and heavy oil, it will be a devastating blow to the refining industry. Our fuel vehicles and gasoline vehicles will have no fuel to refill, which in turn will further accelerate the development trend of transportation electrification. We believe that this trend has already begun.

I just talked about cars and boats, and airplanes. There are currently more than 20 well-known companies developing electric aircraft around the world. There are electric aircraft in Europe and America. The simplest electric aircraft is our drone. Nowadays, drones are basically electric. Regarding the development trend of electric aircraft, we believe that commercial operation can be achieved by 2030. This is an electric aircraft designed by Boeing. In 2030, Boeing will launch a commercial electric aircraft line. This is an American electric aircraft company that Geely just acquired.

Tesla President Elon Musk once said: "Except rockets, all transportation can be electrified." We think Elon Musk was wrong when he said rockets could be electric too. NASA has a special laboratory to study plasma rocket propulsion, which has already entered experiments. In the future, the power for interstellar flight will be plasma propulsion, which is electric. Therefore, we conclude that as long as it is transportation, it can be electrified. Therefore, we created an English word that is not in the dictionary. We made it ourselves, called Electriclize Everything. The electric era is coming. We have now built a new application on the Internet of Vehicles platform called Internet of Boats. The platform for Internet of Vehicles has been established. Next, after the power ship is launched, we can add another variety, not only for car charging, but also for It’s the recharging of the boat. So our first big judgment is that the era of electric everything has arrived.

Second, mobile energy Internet.

We believe that the mobile energy Internet composed of electric vehicles, distributed energy, energy storage and smart grids is about to emerge. We know that mobile phones have promoted the development of mobile Internet, and this is how the concept of mobile energy Internet came about. Yesterday, Chairman Chen Qingtai predicted that by 2030, the sales of electric vehicles will exceed 1.5 million and the number of electric vehicles will exceed 80 million. . We believe that this data is the lower limit of the forecast. We believe that we have sufficient confidence to predict that the number of electric vehicles in China will exceed 100 million in 2030. The power of these 100 million electric vehicles exceeds 1 billion kilowatts, which is equivalent to all current power stations and coal-fired power stations in China, equivalent to 50 Three Gorges. In 2040, the number of electric vehicles may exceed 200 million, equivalent to 100 Three Gorges power stations. This is not the most important thing. The most important thing is that these 100 Three Gorges power stations are moving and changing every moment.

How to deal with a huge mobile power supply? After adding intelligent factors, we believe that the development prototype of the mobile energy Internet has begun to emerge. In this mobile energy Internet, every electric vehicle should be a mobile power generation terminal. Now V2G technology has no technical obstacles. It has been fully realized in our laboratories and demonstration stations. Now V2G only needs is the government’s electricity price policy. What’s the next step to get online? Dispatch interaction with the grid? Our second concept is the concept of mobile energy Internet, which is already ready to come out. Next, a question will be raised. If every electric vehicle can be charged and discharged, then every electric vehicle will become an energy user and producer, and become a power source. The direct problem it brings is that if a thousand electric vehicles interact with the power grid, then our current power grid dispatching will have no problem and can be dealt with. If 10,000 units interact with the power grid at the same time, the current dispatch will basically stop functioning.

Let’s say that by 2030, if there are 10,000 or 100 million electric vehicles, it is possible to interact with the power grid anytime and anywhere, to charge and to discharge, then what should we do? How can we support this system? To deal with this problem, we have already taken action.

The third blockchain technology promotes the mobile energy Internet.

We have introduced blockchain technology into the current Internet of Vehicles. Blockchain technology is applied to mobile power supplies. This is the most powerful implementation of blockchain technology in the industrial field. With these 100 million electric vehicles, it is impossible for you to wait until 11pm every Double Eleven to start selecting products, entering passwords, ordering quantity, and making payments. This is impossible. So what to do? It must be intelligent. In the future, the interaction between the power grid and the tram, this dispatch must be a smart brain, a super brain. We will definitely adopt new technologies, we areBlockchain technology. Blockchain technology actually maps these power grids and electric vehicles in the physical world to the virtual world with fidelity. We people in the physical world cannot handle 100 million devices interacting at the same time. We map them to the virtual world with fidelity. Smart technology can do it.

To this end, State Grid Electric Vehicle Company has established China’s first energy blockchain laboratory. Our 1.0 products have been successfully researched and blockchain edge computing equipment has been installed in interactive charging On the pile. This is our equipment. On the left is an interactive charging pile. The small box on the top is the "mung bean" edge computing terminal. It is not modular yet. If it is modularized, it will be made into a module as big as a fingernail. It is only in the experimental stage now. , which is still relatively large.

We generated the world’s first energy blockchain hash value on May 31, 2018. We have made this hash value into a commemorative medal, and it is the world’s first generated energy area. Regarding the hash value of the blockchain, we have registered the "Mung Bean" trademark. This is our blockchain experimental platform and is now running. It is also the world's first practical energy blockchain platform. This is the Hash value generated every moment on the blockchain platform, producing the mapping of our blockchain. This is the mobile version of our blockchain platform. We have implemented the transfer and transaction of generated "green beans" through the mobile version. The first stage is to install the stake and install the blockchain on the pile; the second stage is to install the energy storage and battery; the third stage is to install the car and the power system of the car. If we complete these three steps, we will no longer need to scan codes when charging our cars in the future, and we will no longer need to take out our mobile phones to pay. We will achieve initial non-intrusive, intelligent, and safe charging and payment. At present, we have already entered the the second stage.

What I will report to you today includes the electrification of transportation. Our State Grid Electric Technology Innovation Center has just been established, called the Transportation Electrification Innovation Center. Our concept covers not only cars, but also boats. Planes, and aircraft. As I said just now, there are still rockets in the long term. This is for the application of energy blockchain in the field of electric vehicles. The short-term goal has reached 1.0, energy storage is 2.0, and driving is 3.0. In the next step, based on the overall intelligent development of the power grid, blockchain technology will be used as the core supporting technology of the future mobile energy Internet.

Due to time constraints, I will simply report here. Please forgive me for any inappropriateness. Thank you!

Ⅱ What exactly does blockchain refer to, and what does it involve? Which disciplines or fields

What is blockchain? Blockchain applications mainly include Internet technology and information content encryption algorithms, combined with appropriate rules and systems, to form a reliable system software infrastructure. The infrastructure here can be interpreted as the online environment. What does this trust mean? Database encryption methods can be divided into symmetric encryption algorithms and symmetric encryption. Symmetric encryption has higher security, but slower response speed. The elliptic curve encryption technology used in blockchain technology is the fastest method among non-asymmetric encryption algorithms. Therefore, the encryption algorithm of blockchain technology is very powerful and it can ensure the uniqueness of the customer's identity. In addition, the information in blockchain technology is also protected by data encryption and is difficult to forge.

The blockchain system avoids the above three problems. The behavior of each node is different from other nodes. The behavior of the node is determined by the program in advance. The regulations are stipulated, and the encryption algorithm ensures that every connection point cannot violate the regulations. This is the connotation of grassroots democracy in the system. Blockchain applications are generally used to build trading software, and it is necessary to ensure that the transaction information content is authentic, valid, traceable and cannot be tampered with. Each transaction information is verified and stored in a zone, and the blockchain information is encrypted through hashing technology to ensure that the information cannot be forged. This blockchain forms a transmission chain in chronological order. Each node has complete blockchain information. If the information content of some nodes is destroyed, the blockchain information will not be affected. This type of archival information method is called a distributed ledger.

In such a distributed ledger of blockchain technology, the actual operation of adding a new record and linking it to all nodes must be carried out according to certain rules, otherwise nothing will be true and effective. . This standard is the consensus mechanism of blockchain technology. In essence, a fair and equitable consensus mechanism should allow all nodes to improve the blockchain. When the contents of the added blockchains are different, they should be negotiated according to certain standards until the contents of a certain blockchain are accepted, and then all nodes will copy this blockchain. Instead of equalizing the amount, not all nodes can be added to the blockchain. Instead, a point eligible to be added to the new server block is selected based on certain criteria and the blockchain information added by the node is copied. Blockchain technology uses the latter, and since the election rules are open and transparent, the election ceremony will become the entire competition process.

Ⅲ Energy Blockchain Research丨Four major blockchain development trends that are expected to become "evergreen trees"

Blockchain technology continues to develop and expand to adapt to the financial market and the Internet market needs and continue to provide digital solutions.By integrating blockchain technology in Web3 technology, we are developing decentralized finance (DeFi) services and decentralized applications (DApps) to enhance the digital ecosystem.

Experts estimate that by integrating blockchain technology and solutions, banks can save $12 billion or more annually. The United Nations also uses blockchain technology to address issues related to human rights violations, fund international humanitarian development, and promote environmentally friendly blockchain ecosystem innovation.

One of the challenges with blockchain trends is that they are fleeting because the industry is constantly evolving. Therefore, some companies and developers often have questions about the development of a certain blockchain project. However, after diligent research and analysis, we found that the following four projects have the potential to become “evergreen” blockchain development trends. What’s more, these four projects are actively providing blockchain solutions to developers in the decentralized finance and decentralized application industries.

1

Blockchain Applications in Enterprises

Developers who want to create high-quality decentralized applications can do so with Jelurida's flagship blockchain Solutions "NXT and Ardor" to build scalable applications that meet market needs. To put it simply, Jelurida is working hard to seamlessly connect physical companies and enterprises with the blockchain industry. Imagine, is a blockchain without practical application still a blockchain?

Futurecoin is the world's first open source blockchain platform that relies entirely on Proof of Stake (PoS) consensus. Proof of Stake is an algorithm based on Byzantine fault tolerance that eliminates computational loss in the Proof of Work (PoW) model and improves transaction security.

Developers can leverage the Futurecoin framework to build and save custom blockchain solutions and create reliable exchanges for tokens. On the other hand, AdoCoin’s sub-chain functionality allows organizations to build permissionless blockchain digital solutions and run smart contracts.

By using these solutions and Ignis, Jelurida has achieved some success. Unlike some blockchain companies, Jelurida has achieved all milestones in its development path and currently operates in several countries on three continents.

Currently, Jelurida has many real-life projects running on its platform, one of which is Cycle4Value, an environmentally friendly gamification system that can control traffic conditions and improve public health.

2

Gaming and Non-Fungible Token Development

Enjin is for blockchain developers in the gaming and non-fungible token industry is another welcome advancement that provides creative developers with the ability to createOpportunities for next-generation decentralized software and applications. Enjin powers real-world projects in the medical, political, financial, and entertainment sectors, and is proud to provide blockchain solutions to millions of users. The project has a market capacity of nearly 45 million, more than 2 million wallets have been installed, and more than 1 billion assets have been created.

One of the real-life projects built on Enjin, "Go! By Health Hero" is a future currency-based solution that can promote the development of health-related projects and services. This project is currently very popular. . Other projects include Microsoft's Azure Heroes, "Lost Relics" and "Age of Corruption" for gamers.

Currently, Enjin is deeply cooperating with the emerging future currency industry. It is expected that as the industry develops further in the future, Enjin will play an important role in the industry.

3

Speed ​​and data security

When a developer wants to create a decentralized blockchain service with scalability and reliability, Speed ​​and safety are the basic factors he needs to consider. Elrond has done just that, processing more than 10,000 transactions in one second, which is 100 times faster than Bitcoin and Ethereum combined.

Here are some of the “evergreen” trends we need in the coming years.

Elrond uses an adaptive state sharding mechanism to support fast verification and transaction processing. Like Jelurida, Elrond uses proof of stake to save resources and improve transaction security.

With over 90,000 active accounts and a large number of development projects, it’s no surprise that Elrond’s ecosystem valuation has jumped from $10 million to $500 million. Elrond operates in approximately 30 countries and counts more than 115 companies and startups among its clients.

4

Environmentally friendly system

Cudos is a broadband blockchain platform that provides blockchain projects with computing resources by integrating the computing resources of developers and users around the world. power. The platform serves as a network for developers to share and sell common resources, enabling reliable and scalable blockchain projects on the Internet. Developers can build and publish decentralized applications, mine cryptocurrencies and amortize network fees.

Gaming and non-fungible token developers and markets, including other related blockchain businesses, can leverage the Cudos framework to create high-quality and secure decentralized solutions and products. The Cudos ecosystem is committed to providing developers with cheaper, more convenient, reusable and environmentally friendly blockchain solutions; providing organizations with cloud computing-based blockchain solutions; introducing innovative solutions into the Web3 framework, Allow developers to create the next generation of decentralized applicationsprogram.

Cudos recently partnered with blockchain-based carbon credit company ClimateTrade to offset its carbon dioxide emissions. The world is currently experiencing the negative impacts of climate change, and businesses and individuals have a responsibility to quickly mitigate and ultimately reverse these impacts.

“

Conclusion

Blockchain platforms committed to next-generation blockchain services and businesses should take measures to solve environmental pollution problems, thereby providing a Chain digital solutions create an eco-friendly environment.

IV What is blockchain technology? What exactly is blockchain?

Blockchain technology is one of the top ten typical judicial technology applications on the Internet. Blockchain Chain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm.

Blockchain is an important concept of Bitcoin. In fact, it is a decentralized database . Blockchain, as the underlying technology of Bitcoin, is a series of data blocks generated using cryptography methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate The next data block.

Blockchain originated from Bitcoin. On November 1, 2008, a person calling himself Satoshi Nakamoto published "Bitcoin: A Peer-to-Peer Electronic Cash" The article "System" explains the concept of the electronic cash system framework based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., marking the birth of Bitcoin.

(4) Extended reading on energy Internet blockchain technology:

The birth of blockchain:

First proposed by Satoshi Nakamoto in 2008 introduced the concept of blockchain, which in the following years became a core component of the electronic currency Bitcoin: a public account for all transactions. The blockchain database can be autonomously managed through the use of peer-to-peer networks and distributed timestamp servers. .

The blockchain invented for Bitcoin made it the first digital currency to solve the problem of repeated consumption. Bitcoin design has become a source of inspiration for other applications. December 20, 2016, Digital Currency Alliance - China FinTech Digital Currency Alliance and FinTech Research Institute are officially established.

IV Energy Blockchain Research | Blockchain use cases in the energy industry

If implemented properly, blockchain technology Has the potential to revolutionize every aspect of the energy industry.

As the energy industry becomes increasingly decentralized, blockchain technology is ideally positioned to be a major disruptive force. ThingsIn fact, companies around the world are already developing blockchain applications to create direct connections between energy producers and consumers.

Blockchain is a virtual public ledger that records transactions in a secure and transparent manner without the need for third parties such as banks, public institutions or electricity providers to act as intermediaries. But how exactly can blockchain be used to improve operations in this area? Let’s explore some of the most exciting applications of this promising technology in the energy sector.

Energy Sector

◆Facilitates peer-to-peer energy trading◆

Traditional energy delivery models rely on centralized power plants millions of miles away, which are located Electricity is transported on transmission and distribution lines, commonly known as the "grid". The less discussed “microgrids” are local grids that can connect and disconnect from the traditional grid when necessary. Microgrids use local energy sources such as wind and solar power to power local loads together.

Microgrids enable consumers to both produce and consume energy, giving them the opportunity to become "product consumers." As producers, they are able to sell any surplus energy they may have on a pay-per-use basis to peers connected to the same microgrid. Blockchain technology facilitates this peer-to-peer energy trading by providing microgrid members with a secure and transparent distributed ledger. This provides a highly reliable and cost-effective way to create, verify, record and coordinate peer-to-peer energy transactions in real time.

Energy Sector

◆Let electric vehicles continue to drive◆

According to data from BloombergNEF, global electric vehicle sales exceeded 2 million units in 2018, more than at the beginning of this century There is a significant increase in the number of thousands of vehicles a year. Additionally, Bloomberg expects this number to increase to 10 million by 2025 and 56 million by 2040.

With more and more electric vehicles on the road, private charging stations are likely to become valuable assets, requiring an efficient system to coordinate energy transactions between drivers. Blockchain technology can be used to create a system that can monitor electricity prices, make pricing decisions in specific markets, and enable charging station owners to conduct secure transactions.

Energy Sector

◆Simplify regulatory procedures ◆

Energy companies need to submit large amounts of data to regulators to prove their compliance with various regulations. Collecting and cleaning all this data using current technology is not only tedious, but also creates serious problems related to incorrect data access. The more data you process, the more people you need to be involved, and the greater the chance of accidental exposure of sensitive company information.

Since blockchain ledgers are both immutable and fully transparent, introducing them into energy companies’ operations will create the greatest potential for regulators.Confidence that the data they receive is unedited. The introduction of blockchain will also give energy companies unparalleled control over what information is shared with whom, all but eliminating the possibility of sensitive data falling into the wrong hands. To boot, blockchain technology introduces the ability to standardize data collection and transmission formats.

Energy Sector

◆ Expanding energy access ◆

Many communities around the world are not connected to the grid. Energy in these communities often comes from local solar panel projects, many of which do not receive adequate funding.

Crowdfunding can help close this financing gap. The idea here is for individuals or other small investors to pool their resources to purchase enough photovoltaic cells to build the necessary number of solar panels for a given community without electricity. These micro-investors retain partial ownership of the solar panels and earn income, with the community paying a marginal amount each month for the electricity generated by the solar panels.

Introducing blockchain technology into this process will alleviate many of the problems that plague traditional crowdfunding. First, blockchain-based crowdfunding will enable anyone with an internet connection to donate to a campaign, which is simply not the case with traditional crowdfunding platforms. Additionally, just like peer-to-peer energy trading within microgrids, blockchain technology can reduce the overall cost of monthly transactions between solar panel owners and the community powered by the panels. Finally, because blockchain is completely secure and transparent, blockchain greatly reduces the chance of crowdfunding fraud. On the contrary, it is difficult for traditional crowdfunding platforms to eradicate this kind of fraud.

Energy Sector

◆ The bright future of blockchain◆

These use cases show that blockchain applications have the potential to revolutionize our energy consumption, transactions, Regulation and financing methods. Once key stakeholders in the energy industry get involved, blockchain may well become the key to keeping the lights on for millions of people around the world.

Block VI What are the advantages of using blockchain technology in the energy field

Chongqing Jinwowo analyzes the advantages of using blockchain technology in the energy field as follows:
1. Provide distributed energy trading and supply system
2. Smart contracts that can use blockchain technology in the energy sector
3. All energy flows support secure records

Ⅶ Energy Blockchain Research | Why we need blocks Chain Technology

When talking about blockchain technology with outsiders, they will always mention this question: Why do we need blockchain? If the answer is not appropriate, even people who are interested in it may not I want to know more about it and will letThey believe that blockchain does not bring anything new to the world.

In fact, blockchain technology has begun to get on the right track, and many industries have begun to use blockchain technology. Blockchain doesn’t always solve old problems in new ways. Compared with traditional methods, blockchain technology is safer, more cost-effective, and more transparent. This article will give answers to the above questions.

As we all know, the 21st century has brought about issues such as data breaches, misuse of personal information, and data insecurity. Blockchain combined with other technologies and services can help prevent some major information leaks and breaches because data is no longer stored in one place. If we want to truly understand how blockchain technology can help ordinary users, first, we must understand the types of services and platforms they use. For example:

Some blockchain companies are trying to replace all the products in the picture above. These attempted products are either decentralized or replaced by decentralized products. Many companies have shown time and time again that they don’t trust data and that users should get more out of it by selling their data to advertising companies.

The 2017 ICO boom swept the blockchain market, with hundreds of companies succeeding or failing seemingly overnight. But there are also benefits to this special investing period: Investors have learned how to spot innovative, high-quality companies. Some companies founded through ICOs still exist, while others raised funds during this period. The idea common to most companies is this: they allow users to control their data without interference or hosting. For example:

But is anyone really using these alternatives? The answer is yes, and it's growing well. Of course, some projects fail miserably and drag down the industry. After the ICO boom in 2017, if you pay a little attention, you will find that not all of these companies are successful. However, success often comes with failure.

Even some early projects that seemed very successful have gradually lost their former glory, such as CryptoKitties. But you can learn how to get better from failure. The entire industry, users, developers and investors learned a lesson in a previously oversaturated market: it learned how to get better. Users learned how to better allocate their time among many new projects; investors learned which projects to invest in; developers learned what works and what doesn’t; and the industry learned how much new development is sustainable of.

Good ideas are no longer enough. There also needs to be a working product, a dedicated user base, and a concept. This is why Brave, Antube, and Alfa are some of the most forward-thinking projects on the market today—they answer the big question of why we need blockchain.

Data is important. When surfing the Internet, most Internet usersEveryone is providing data. This data is collected, classified, and monetized by large corporations. From this they learn who the user is and why they are buying. How to get users to buy is the key to their success. Alfa, Brave, and Antube are three unique companies trying to give users more control over their data.

Brave aims to transform the browsing experience. Previously, most people installed ad-blocking software on their browsers, but Brave is about to change that. Instead, the ad becomes an interactive experience that captures the user's attention in a short period of time, and all parties benefit.

Users should have more control over their data, but relying solely on blockchain and tokens will not solve the problem. A new blockchain with built-in economics should be developed.

Back to the original question: Why do we need blockchain?

It’s all about data. In the past, we relied on organizations to save data, but now blockchain provides users with keys and immutable records.

There are many ways to track the progress of a company or institution, but the easiest way is often to go straight to the source. Twitter will update in real time (Brave, Alfa, Antube), and checking forums such as Reddit, Bitcointalk, and articles on Hacker Noon can also provide valuable information. Whichever way you choose to update, just remember this: we want “our” data to belong to “us” — that’s why we need blockchain.

Ⅷ Future Blockchain technology will change these 18 major industries

Blockchain technology will change these 18 major industries in the future
Since the birth of the Internet, the cost of information dissemination has been greatly reduced, and the efficiency of information dissemination has increased rapidly. Social productivity has been liberated as never before. It is no exaggeration to say that the Internet has changed the entire pattern of human society.
However, while enjoying the many conveniences brought by the Internet, we have to admit that the Internet still has many flaws, especially in terms of security and mutual trust. The birth of blockchain technology has brought a new dawn to solve the problems existing in the Internet society.
Because blockchain technology is open and transparent, difficult to tamper with, and does not rely on intermediaries, blockchain can achieve safe, efficient, and low-cost value transmission. People are expected to build an Internet for value transmission based on blockchain to further promote the liberation of social productivity.
At the same time, just as "every new technology appears will change or even subvert many industries", in the future blockchain will changeTransform these 18 major industries!

1. Banking Industry
The application of blockchain technology in the financial field will change the transaction process and record keeping methods, significantly reduce transaction costs, and significantly improve efficiency.
2. Cybersecurity
Although blockchain is not a panacea to fix all Internet problems, it can be a powerful tool for experts and engineers, especially systems with single points of failure and centralized vulnerabilities.
3. Supply chain management
The supply chain is a complex functional network chain structure composed of suppliers, manufacturers, distributors, retailers, and users. In this chain, capital flow, information flow, and physical flow operate interactively, making coordination extremely difficult. The traditional coordination mechanism that relies on a single "chain owner" has encountered bottlenecks. The "decentralized" model of blockchain provides rich imagination for solving this problem.
4. Prediction field
The prediction market needs a platform that is decentralized, open and transparent, and more adaptable to global user participation to change the status quo, and this naturally matches the characteristics of the blockchain. Whether from sports betting to stocks to elections, these technologies allow for decentralized betting and observation.
5. Network and Internet of Things
The idea of ​​applying blockchain technology to the Internet of Things (IoT) has been around for some time. In fact, blockchain technology looks to be a suitable solution for at least three aspects of IoT: big data management, security and transparency, and micro-transactions based on the exchange of services between interconnected smart devices. Comes in convenience.
6. Insurance industry
The power of technology is making the insurance industry return to its essence: linking objects, regaining trust, and sharing. In other words, the law of large numbers in the traditional insurance industry may encounter more uncertainties and create new possibilities due to technology, technology, and links.
7. Sharing Economy
Blockchain is inherently decentralized, which is highly consistent with the purpose of the sharing economy. The "Tencent Blockchain Solution White Paper" shows that Tencent is applying smart contracts to bicycle rental, house sharing and other fields. If this smart contract is applied to today's popular bicycle sharing field, it may bring new changes to the entire industry.
8. Cloud Storage
Blockchain technology can support distributed storage of encrypted data and is the core of collaborative cloud storage.
9. Charity industry
For charity, the openness and transparency brought by blockchain technology can ensure that donors can clearly understand the flow of their funds and can query it; the non-tampering feature can also ensure that financial Information cannot be tampered with; anonymity also protects donor privacy.
10. Voting
Blockchain technology can be applied to voter registration, identity confirmation, and electronic statistics to ensure that only legitimate votes are recorded and that votes will not be tampered with or removed. Create an immutable, publicly visible ledger of voting records to make elections fairerand democratization.
11. Government Management
Government services are one of the most direct and significant application areas of blockchain technology. Information exchange across agencies will effectively improve government efficiency.
12. Public welfare industry
Internet culture itself has the genes of equality, openness, and mutual assistance, which is very consistent with the characteristics of public welfare.
13. Medical industry
The medical industry currently still relies on old systems and lacks ways to store data securely. Blockchain can be widely used in medical and health information sharing, medical process transparency, and medical accident liability traceability.
14. Energy Management
In order for the Energy Internet to be successfully implemented, various information interactions, smart grid control and scheduling, and coordinated control of distributed power sources are all obstacles that must be overcome, and blockchain Technology is trying to solve these problems.
15. Music Copyright
The importance of music copyright is self-evident to online music platforms. Having more copyrights means that it can capture more users, and the platform can therefore obtain better Development opportunities.
16. Retail industry
When we shop, we need to trust the store’s retail system. Decentralized blockchain can make retail different, as buyers and sellers can connect directly without middlemen and fees.
17. Real Estate Industry
Blockchain technology can change the way the real estate market operates. It can merge many complex processes and cases that real estate companies usually deal with, speed up transaction processes, reduce fraud, and provide benefits for everyone. Participants provide more transparent and secure transactions.
18. Your industry
If your industry deals with data or any trading system, it is very likely to be changed by blockchain. This is an open field full of opportunities.
Of course, as an emerging technology, the application of blockchain still faces many challenges. More blockchain technology companies like Matrix are needed to overcome the difficulties in practical application of blockchain and promote blockchain technology. The widespread application and development of chains.

Ⅸ Introduction to Blockchain Technology What is Blockchain Technology

1. Blockchain technology is one of the top ten typical judicial technology applications on the Internet.

2. Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

3. Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

4. Among them, the data layer encapsulates the underlying data blocks and related basic data such as data encryption and timestamps.Basic algorithms; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates various consensus algorithms of network nodes; the incentive layer integrates economic factors into the blockchain technology system. , mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, which is the basis of the programmable features of the blockchain; the application layer encapsulates various application scenarios and case. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

5. The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". Among them, "the minority obeys the majority" does not entirely refer to the number of nodes, but also to computing power. , number of shares, or other characteristic quantity that a computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result. Taking Bitcoin as an example, Caizihe uses proof of work. Only by controlling more than 51% of the accounting nodes in the entire network can it be possible to forge a non-existent record. When there are enough nodes joining the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
