❶ What is the relationship between blockchain and artificial intelligence
Blockchain and artificial intelligence have many potential connections and interactions, and they can promote each other and make up for their shortcomings , so as to make progress together.
On the one hand, at the application level, artificial intelligence technology Liang Suichen can provide the blockchain platform with more complete data processing and analysis capabilities. For example, artificial intelligence technology can help blockchain platforms conduct large-scale data mining and analysis, discover hidden correlation patterns and trends, and improve data processing efficiency and security. At the same time, blockchain technology can also provide a more accurate, real-time, and credible data source for artificial intelligence algorithms by establishing a decentralized, non-tamperable data storage and transmission mechanism, further improving its decision-making and prediction capabilities.
On the other hand, at the technical research level, blockchain technology and artificial intelligence technology also have the possibility of integrating with each other and accelerating development. For example, some researchers apply blockchain technology to decentralized artificial intelligence training and data collaboration processes to solve issues such as privacy protection and data traceability in the current artificial intelligence field; other researchers are exploring How to use artificial intelligence algorithms to optimize and accelerate the blockchain transaction confirmation and on-chain data verification process, and further improve the development efficiency and security of blockchain technology.
In short, in the field of cross-application of blockchain and artificial intelligence, they can promote and support each other, and produce more complex and diversified technological innovation combinations, which can contribute to the development of the digital economy and enterprises. Have a positive impact.
❷ Inventory of the 6 core tracks of the Metaverse in one article
Inventory of the 6 core tracks of the Metaverse
01. Games/Social
With the continuous development and maturity of technologies such as the Internet, blockchain, and metaverse, the content industry under the new organizational form of the Internet will inevitably follow suit. New breakthroughs have occurred:
1. Content density and interaction have reached a new level
2. Users have greater freedom and authority
3. Distribution has improved Centralization
The two major development directions in the gaming field: UGC games and blockchain games have received basic support for their development and are expected to become the vanguard of the metaverse wave. More importantly, games exist in a virtual electronic form and have a very strong mutual attraction with the concept of the metaverse. The Metaverse brings the reality of real life into games. Equipment and assets in virtual games can be linked to reality, and players can even build a complete industrial chain through games.
At present, the more representative metaverse games include Axielnfinity Decentraland and Roblox. Their characteristics include decentralization, monetization, open source, etc.
02. E-commerce
Technologies such as VR, AR and digital simulation will reconstruct onlineIn e-commerce scenarios, Metaverse has broad application prospects in retail. In the metaverse, you can create a shopping mall and complete your consumption in a game-like experience through the simple operation of placing an order with one click. In addition, Metaverse can also get rid of the form and function of physical stores, and more imaginative digital shopping experiences are being developed. The experience provided by Shenman Technology for retail e-commerce scenarios is changing the consumption patterns of users in the e-commerce field.
Gucci cooperates with Roblox to launch The Gucci Garden Experience virtual exhibition. Players can enjoy the exhibition and purchase virtual items. Tmall has launched a 3D version of Tmall Home Decoration Mall to provide consumers with a 360° presentation of furniture decoration effects, helping users browse different styles of decoration designs and make decisions. As the pandemic prevents consumers from frequenting beauty counters, L'Oreal is currently promoting Modiface AR technology to help customers try on cosmetics, such as lipstick shades and hair colors, through their phone cameras.
03. Office
Meta CEO Mark Zuckerberg said when talking about the Metaverse that the Metaverse widely helps people experience a sense of existence. Sense makes the way we interact more natural. Many of the meetings we have today are looking at a grid of faces on a screen. But we're used to being in the same room with people and having a sense of space, and if you're sitting to my right, that means I'm sitting to your left. In the future, you'll be able to sit on my couch like a hologram instead of just doing it over the phone.
Remote working has become more common under the influence of the new crown epidemic, but traditional remote working still faces some problems, such as lack of real-time interaction and low communication efficiency. The Metaverse can enable virtual office to be conducted in a face-to-face interaction manner. Google has launched Project Starline, which aims to create a 3D remote interaction format where participants can observe the chat partner from different angles and make physical or eye contact.
Facebook launched Horizon Workrooms, a remote collaboration tool that allows colleagues wearing VR devices to communicate face-to-face in the same virtual conference room, breaking the barrier of the screen.
04. Digital Collections
The domestic digital collections market is a branch of the metaverse that emerged after the overseas NFT concept. Due to strict regulatory policies and unclear policies, the industry formed is not yet complete. Among the many domestic digital collection market participants, technical service providers provide basic blockchain technology and related services as the infrastructure layer for digital collections. Numerous digital collection casting platforms provide digital collection providers with a package solution for casting, issuance, and sales of digital collections, and have become the primary trading market for the domestic digital collection industry.
In addition, although domestic digital collection distribution is mostly based on the PGC or UPGC model, in terms of quantity alone, 90% of the copyright-owning suppliers are individuals, which forms a leading supplier.Most of them are enterprises or organizations, and the digital collections issued by them are in short supply and have a price but no market. Followed by excellent individual suppliers and the second-tier corporate suppliers, and finally a large number of ordinary individual suppliers, forming a three-level and well-defined pyramid structure.
05. Virtual people
Virtual identity is the most basic dimension of the Metaverse. It has diversified application scenarios and commercialization paths. High fidelity, intelligence, and tooling are the characteristics of virtual people. Three major development trends. At present, the development of Nianduan virtual humans is in the stage of diversified development. The technology continues to mature and develop in various directions. Hyper-realistic virtual humans exist beyond the 2D form and can achieve independent emotional expression and communication. Virtual humans sprouted from early hand-drawn and 2D animations, and the concept of virtual humans was introduced from the film, television and music industry.
When virtual humans enter a stage of rapid development, deep learning algorithms, AI and other technologies have promoted the development of motion capture, expression capture, rendering and other technologies. Virtual humans can highly restore the image of real people and achieve real-time driving. Emerging technologies in various fields have promoted the accelerated growth of the virtual human industry. In recent years, virtual humans have placed more emphasis on the combination of AI and virtual humans, aiming to be applied in daily life and pan-entertainment scenarios.
06. Industry
Nvidia CEO Jensen Huang said in an interview that companies can rely on Yuanverse to reduce cost waste and improve operational efficiency. We're wasting a lot of stuff to compensate for the fact that we're not simulating, we're simulating factories in the metaverse, simulating plants, simulating real-world power grids and saving billions of dollars.
The industrial metaverse is a virtual space that is parallel to and independent of the real industrial world. It is a true reflection of the real industrial world in the digital world and a holographic digital industrial world.
Moreover, with the continuous development of cloud computing, 3D design, virtual reality (VR), augmented reality (AR), digital life, artificial intelligence, Internet of Things, blockchain, 5G, 6G and other technologies, With development and improvement, the industrial Yuanyu will become more mature, and the virtual industrial world will become closer and closer to or even surpass the real industrial world. When any aspect of industrial design, production, and manufacturing is empowered and supported by a widely used and mapped virtual world, this marks that the manufacturing industry has officially entered the era of the industrial metaverse.
❸ How to define blockchain and what are the application scenarios of blockchain?
Nowadays, many people think that blockchain is a universal technology that can do anything, which is somewhat different. Blockchain technology is a myth!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.
Definition of Blockchain: Narrow VS Broad
As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.
The characteristics of blockchain technology include:
Blockchain is a system that is distributed around the world and can operate collaboratively. Database storage systems are different from traditional database operations - read and write permissions are in the hands of a company or a centralized authority (centralized characteristics). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).
At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.
At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.
As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.
Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.
The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything else. Some people said that this was the arrival of a new era, and the past has become classic, while others said To say that everything is hype is ultimately a bubble.
In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.
Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.
Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, and does not confirm the rights in real time during the process of evidence generation, the entire rights confirmation process takes a long time, and the evidence collection is difficult and costly. It is extremely difficult to trace the source, and it cannot meet the characteristics of rapid spread and large quantity of online works.
eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated in the process in real time. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.
Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.
Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.
Through the following limited cases, I hope everyone can understand the actual performance of blockchain technology, thereby stimulating interest in such solutions.
1. Administrative Services
Over the centuries, the roles and responsibilities of public administration have not changed significantly – or rather, what has changed dramatically is actually the size of the data and the specific ways in which public agencies handle it. Although various digital technologies already exist to help collect and process data, issues such as anonymization, portability, and the immutability of large amounts of data remain unresolved.
Sasha Ivanov, founder, entrepreneur and CEO of Waves Platform and Vostok projects, said, "What the public administration currently lacks is a more convenient user experience (UX) for data use. To improve the user experience , we should introduce some kind of layer into it that acts as a trusted public environment that is transparent and able toStore data anonymously and immutably. ”
Governments around the world are gradually facing the existence of such problems by launching federal agency and enterprise-level programs such as the U.S. Federal Blockchain Initiative. The United States held the first federal district conference in July 2017. Blockchain Forum, and the U.S. General Services Administration currently has more than 200 related use case repositories. Ivanov explained, "Distributed systems can really help us establish such a reliable environment, improve our big data work, and even Bringing all emerging technologies together—including artificial intelligence, the Internet of Things, and more. In fact, whenever we face any kind of technology, it always embodies the sum of other technologies. ”
Now, the system supported by the blockchain can actually work - this view has been unanimously recognized by all experts and has become the most important theoretical basis. In other words, next we have to What we do is to create more production-ready solutions.
2. Payment services
The government needs to process transactions, many of which involve the exchange of funds with citizens. District Blockchain technology has huge potential application value in reducing the cost of fund transfers - including using new blockchain-based cryptocurrencies as intermediate transaction carriers, or using blockchain as a means of fund transfer, etc. Once a perfect solution is found , the business opportunities contained therein will be endless - especially for those who need to conduct frequent cross-border or Internet transactions.
The Jasper project was developed by the Bank of Canada to help it further think about central banks And how other financial institutions should implement payment operations between different banks based on distributed ledgers. The Bank of Canada has also developed its own digital currency variant "CAD Coin" to test the use of a certain national currency on top of the blockchain The feasibility of it.
This project brings an interesting conclusion, that is, we should say no to the proof-of-work public chain system. In an article titled "Jasper Project: Is a distributed batch payment system feasible?" "In the paper, the author observed that "Proof-of-work systems are not suitable for such large transaction processing systems because they assume that all transactions in the system require publicity and observability to a certain extent. ”
3. Digitization and Intellectual Property
The government is responsible for maintaining copyright records and databases. These records prove the ownership of intellectual property. A blockchain-based system allows various artists, Performers and writers can time-stamp their works and theoretically detect copyright infringements and even retain permanent records of rights. In fact, many governments have taken important exploratory steps in this direction.
Iran recently announced that it will deploy this technology. "Iran Financial Tribune" quoted Morteza Mousavian as saying that "the Digital Media Department of the Ministry of Culture hasAgreement with a blockchain company to jointly design a system that can be used to protect online copyright. "He also added, "Relevant programs will soon be released to users in an easy-to-use manner. ”
This work is still in the early stages of exploration, but it provides corporate customers with the possibility of preserving records through replication technology. From a theoretical level, companies can use blockchain solutions for financial accounting, And discover the errors in real time.
4. Welfare distribution
The government has the responsibility to create a level playing field for citizens. Citizens who are chronically poor or economically disadvantaged certainly Government support and assistance is needed to ensure that they are able to maintain their lives and acquire the ability to continue to develop. However, welfare distribution is neither simple nor often straightforward. Problems such as corruption and imposters have been seriously undermining government programs. Various distribution channels.
In China, the National Council of Social Security Fund is conducting early research on how to use blockchain technology to improve the delivery of national benefits to citizens. At the same time, India is also taking action , Andhra Pradesh and Telangana are already using blockchain to support their civilian resource supply systems.
It is said that many companies, including Microsoft, are also considering using the same technology. These solutions, which will touch individual employees and functional roles, are expected to gradually appear in small businesses in the near future.
5. Tendering activities
In order to build public infrastructure or provide For related services, governments hope to achieve economies of scale and competitive gains through tendering as much as possible. However, the tendering process is often not fair or transparent. Public procurement has long been a major scene of rampant corruption around the world. Transparency International pointed out, “Many governments will award project contracts to one supplier in the absence of fair competition. This allows companies with greater political resources to unfairly outcompete competitors; or companies in the same industry negotiate bids in advance to ensure that each company gets a piece of the tender pie. This will significantly increase the cost of delivering services to the public – we have found that corruption issues can increase project costs by 50%. ”
So, how can blockchain technology solve the bidding problem? According to Ivanov, “Unlike decentralized centralized systems, independent ledgers powered by blockchain will be able to improve bidding or Transparency of any other financial processes that need to be tracked. The intervention of blockchain technology will help track the use of funds and ensure that they are paid out as expected and within the allowed time. ”
Currently, Japan’s Ministry of Interior and Communications has announced a blockchain-based bidding system, which means that in industries with serious collusion problems, small and medium-sized enterprises are expected to usher in a more transparent bidding method and Ahead of brighter developmentsscene.
Although quite a few of the cases mentioned previously are far from finalized, they do provide many possibilities for companies and governments. Of course, the key lies in implementation; and we should also look at all this with optimism, that is, although blockchain technology is often misunderstood, it is and will eventually find a direction in which it can exert its own energy!
< p> In layman's terms, the blockchain is like a dozen beacon towers on the Great Wall. If an enemy comes at one place, they will send out smoke. The other beacon towers will know about it and enter a defensive state together. In technical language, it is a distributed ledger. Each node keeps accounts separately. The failure of one or two nodes will not affect the entire network.
How is this distributed network different from the distributed servers of Google Network? Google Network's distributed servers still belong to Google Network and are controlled by their central scheduling algorithm. The distributed nodes in the blockchain do not know each other and have no legal relationship. You can just go offline and shut down if you want, but because of the currency rewards, there will always be someone who will turn on the machine as a new node to support the network.
After the popular and technical explanation, I hope you understand. So the first application scenario is finance. I put my money in Alipay. If Alipay doesn't recognize it one day, there's nothing you can do. But on the blockchain, it is useless if one node does not acknowledge it, because other nodes still have my records. The second is the contract. Nowadays, contracts are made on paper and are easy to be faked. But if they are put on the blockchain, they cannot be faked.
There are more application scenarios. It is recommended to check the top 100 digital Huobi online to understand the corresponding projects behind them and become a blockchain expert. .
Blockchain technology was first used in Bitcoin. Blockchain provides a reliable and trustworthy means of organizing data for cross-subject business scenarios. JD.com is essentially a supply chain company, and blockchain technology will be first used in many scenarios of the supply chain.
Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.
The most popular application industry at present is the financial industry.
An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since traffic fraud in digital advertising causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud
In the future, as the application of blockchain technology becomes increasinglyOnce mature, it will be applied in many industries to create a new ecological model based on technological trust
The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to connect people The relationship between them is more equal. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.
Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.
In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.
At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.
What is blockchain If you use non-technical terms to explain blockchain, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone, so In the Internet, a place where data and information are exploding, having such a place would be like a magical treasure.
If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:
Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.
If there are any deficiencies, you are welcome to comment and correct me.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.
The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.
Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire trading network has changed from a star structure to a point-to-point P2P structure.
In the future, blockchain will be used in many fields and will have a great impact on human life. It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.
1. Cloud storage
This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?
Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.
2. Medical aspects
Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.
❹ The implementation of the "Blockchain + Internet of Things Security" international standard led by Changhong empowers the acceleration of smart home applications
Recently, the IEEESA (International Electrical and Electronic Engineering Co., Ltd. The global standards project meeting organized by the Electronic Engineers Standards Institute) was held online. At this meeting, the "Blockchain-Based Zero Trust Framework Standard for the Internet of Things" submitted by Sichuan Changhong Electronics Holding Group Co., Ltd. (hereinafter referred to as "Changhong Holdings") was unanimously approved after full discussion by the international experts attending the meeting. The project was formally established, which is also the world’s first international standard for “blockchain + IoT security”.
After the implementation of this standard, relevant parties will build a trustful Internet through the promotion of the zero-trust framework of the Internet of Things based on blockchain, and realize the application of blockchain technology in the industrial Internet, smart homes, smart health, and smart homes. The implementation of applications in major scenarios such as cities will help accelerate the digital transformation and high-quality innovative development of my country's real economy.
Breaking through key bottlenecks
Accelerating smart home applications
It is understood that the "Blockchain-based Zero Trust Framework Standard for the Internet of Things" proposed this time, It is the first standard proposal launched by the Blockchain Empowering IoT Security Working Group under the IEEEC/BDL Computer Association Blockchain and Distributed Accounting Standards Committee.
“This standard will be the first to propose the technical idea of using blockchain technology to build a zero-trust security system for the Internet of Things at the standard level, providing a replicable and scalable distributed trust core technology framework for native applications of the Internet of Things. , in order to reduce the technical barriers of the Internet of Things security systembarriers and application costs, breaking through the key bottlenecks in industry technological innovation and application development. "A relevant person from Changhong Holdings said.
The security flaw of the Internet of Things lies in the lack of a mutual trust mechanism between devices. All devices need to be checked with the data in the Internet of Things center. Once the database collapses, It will cause great damage to the entire Internet of Things. The distributed network structure of the blockchain allows devices to maintain consensus without the need to verify with the center. In this way, even if one or more nodes are breached, the data of the overall network system remains It is reliable and secure.
“The standardization of this framework will promote the healthy development of IoT applications, provide a trust foundation for the IoT ecosystem, and benefit all participants and stakeholders. "The above-mentioned person in Changhong said.
Tang Bo, chief scientist of Changhong Information Security Laboratory, believes that the combination of blockchain and the Internet of Things will give security and new vitality to the business model in the smart home field.
In the Internet of Things scenario represented by smart homes and the industrial Internet, tens of billions and an ever-growing number of Internet of Things devices (IoT) are changing the existing network structure, and the traditional perimeter security model is being challenged. , The interconnection between heterogeneous and heterogeneous devices requires the establishment of a safe and trustworthy collaboration mechanism. Therefore, there is an urgent need to develop a common framework to deal with the large number of security and trust challenges in the Internet of Things to achieve end-to-end security of the Internet of Things. Credible.
“Breaking the original isolated individuals, blockchain + IoT technology can realize a distributed collaborative network. In the form of blockchain nodes, various smart home manufacturers, home appliance terminal platforms and regulatory agencies are connected to realize the true interconnection of everything, solve key bottlenecks and core pain points, and also enhance the prosperity and compatibility of the smart home ecosystem. " Hong Shibin, founder of Yuecheng Co., Ltd. said.
Major General Ding, founder of Ding Technology, believes that "Anyone, thing, or thing that wants to access the network needs to undergo strict verification to build a security barrier for the Internet of Things. This is very necessary in a future where everything is connected. The introduction of standards can more clearly guide the application of the "zero trust principle" in the field of Internet of Things. Strengthening the feasibility and security of interconnection will help the scale of smart homes to be implemented faster. ”
“For a long time, Chinese companies have often been keen on product production and neglected the formulation of standards, causing Chinese products to encounter many technical barriers in their global expansion. This time, Changhong and other companies took the lead in formulating the world’s first The 'Blockchain + Internet of Things Security' international standard has enhanced the ability of Chinese companies to participate in the formulation of global standards. New technologies require relevant standards to guide the development of related ecological industries. Regarding the industrial ecology and globalization of new technologies, their huge commercial potential requires relevant standards to guide the development of related ecological industries. Chinese companies are already at the forefront, which shows that Chinese traditional companies are in the process of improving standards, product technology, and product barriers. In terms of construction, awareness has increased. " Zhou Xibing, a researcher at the Chinese Local Enterprise Soft Power Research Center, said.
Comprehensive layout of Internet of Things applications
Give direction to the digital transformation of enterprises
Blockchain Internet of Things is A concept mainly promoted by the ITU standards organization. In early 2017, ITU-T established the SG20 standards group, which is responsible for the formulation of standards for the Internet of Things and its application in smart cities and communities. The leading domestic companies are China Unicom, ZTE, and China Information Technology.
This is the first time that a home appliance company has taken the lead.
In recent years, Changhong Holdings has been based on the Internet and oriented to the Internet of Things, accelerating transformation and upgrading, and established an information security lighthouse laboratory in 2018 to make a comprehensive layout Development of blockchain standards for Internet of Things applications.
Tang Bo said that the laboratory will be committed to promoting the development and release of this standard, and recruiting people who are engaged in blockchain application research, testing consulting and engineering practice in the field of Internet of Things Relevant enterprises, industry associations, universities, scientific research institutes, and service organizations are preparing to establish a blockchain-enabled IoT security standards working group to carry out the development of standards related to the security integration and innovation of blockchain and IoT.
“The intelligent transformation of traditional enterprises generally faces the dilemma of high R&D costs, low production efficiency, and insufficient operational capabilities. The current results of Changhong's transformation towards the Internet of Things show that it has blazed its own path in intelligent transformation. Changhong’s AIoT strategy is not only promoting its own transformation, but also empowering external parties to promote industrial upgrading. Overall, Changhong's transformation and upgrading has made obvious progress: on the C-side, Changhong's smart home solutions are constantly improving; on the B-side, Changhong has won multiple industry championships, such as Internet of Things modules, rail transit power supplies, etc. "Major General Ding, founder of Ding Technology, said.
"With the popularization of 5G, the Internet of Everything has entered the transformation track of traditional enterprises, and the construction of new business models has become a step in the upgrading and transformation of traditional home appliance giant manufacturing enterprises. tuyere. In this transformation, Changhong takes advantage of its traditional manufacturing advantages and the needs of the new era. The international standard of ‘Blockchain + Internet of Things Security’ jointly formulated by Changhong will enhance Changhong’s own competitive advantage. ” Zhou Xibing believes.
The implementation of relevant standards is also of great significance.
The vertical application of blockchain IoT involves many fields: industrial manufacturing, networked driverless cars, Transportation, public technical facilities and smart cities, financial services and insurance, home and commercial property management, smart contracts, retail, etc.
"In the future, home appliance giants will be engaged in industrial manufacturing, driverless driving, smart cities and other fields. , has become an important support and even a leader, and it is playing an irreplaceable role. " Hu Qimu, a senior researcher at the China Steel Economic Research Institute, said.
Major General Ding believes: "From a long-term development perspective, the industries and fields that this standard can affect will be quite broad. After all, 'materials' The Internet itself should be used in future production and lifeIt should be ubiquitous. In the short term, this standard will mainly provide standards and direction for the development of smart homes, smart wearables, and smart travel industries, as well as the digital transformation of the manufacturing industry.

It not only subverts the original Internet of Things scenario and improves human life, but also breaks the stereotype of blockchain protocol application in financial transactions, creating a precedent for application in the field of Internet of Things.
(5) Extended reading on blockchain smart home decoration
The significance of blockchain:
The blockchain system itself can Generating credit, this kind of credit-worthy product does not come from a third party, but from a program, because the generation of blockchain record information requires confirmation by all network nodes, and once generated, it will be permanently recorded and cannot be tampered with.
The underlying protocol of the Internet is the TCP/IP protocol, which achieves low-cost and high-efficiency dissemination of information; blockchain can be considered a new underlying technology and establishes a new credit system.
Blockchain replaces the current Internet’s reliance on central servers, allowing all data information to be recorded on a cloud system. In theory, it realizes data self-certification in data transmission, which has a far-reaching significance. In other words, this goes beyond the traditional and conventional information verification model that relies on third parties and reduces the cost of establishing a global credit system.
The sharing economy uses information technology to provide services to individuals, businesses, non-profit organizations and governments, and optimizes resources through the redistribution, sharing and reuse of idle assets and services.
The sharing economy has had a disruptive impact on certain industries by massively releasing previously closed private sector production capacity. When blockchain technology matures, it can directly eliminate the intermediary link and realize peer-to-peer transactions. , the allocation of resources will be more efficient.
❻ Hot! Create and play with your own blockchain in 5 minutes
Blockchain is developing so fast this year! From an unfamiliar concept at the beginning, it has now taken off in various industries. A single spark has the potential to start a prairie fire. I really hope I can have my own blockchain to practice with! But a person,How can a computer set up a blockchain environment that is so popular that it is not easy to love you?
Don’t Worry! The editor has been addicted to blockchain and smart contracts and can’t extricate himself! Now I will take you step by step to start from scratch and create your own blockchain in 5 minutes! ~
The SuperVessel platform developed by IBM China Research Institute provides a blockchain development and testing environment for blockchain enthusiasts and developers. Through this platform, users can create multi-node blockchains based on Hyperledger Fabric for free and super quickly, and play with smart contracts on their own chains.

Preparation
All you need is your local browser!
1. Register an account
Access the public beta address of SuperVessel blockchain service: 8800/bc.
Click the Log in button in the upper right corner, click Register in the pop-up window, fill in your email and password and submit. At this time, it is recommended to check the activation email in your mailbox and activate your account (Editor's tip: It doesn't matter if you activate lazily, but some advanced services must be activated before they can be used).
2.
Quickly create your own blockchain
After registration is completed, return to the homepage and click on the huge GIVE ME A BLOCKCHAIN (Give me a blockchain!) button. Select the Consensus Plugin (consensus plug-in) and Size (number of blockchain network nodes) you want in the pop-up box.
Editor's note: Currently there are two consensus plug-ins officially provided by Hyperledger Fabric: noops and pbft.
After clicking Submit, you will get your own blockchain in a few seconds and automatically enter the monitoring panel. That’s right, getting your own blockchain is that simple!
After entering the monitoring panel, you can see that the left side is the smart contract management panel, including the management and deployment of smart contracts; the right side is the network panel, which displays the applied blockchain network status, topology, and connections between nodes. Latency information, etc. are clear at a glance; click the telescope icon in the upper right corner to monitor the log information of each node in real time. The bottom is the blockchain panel, which shows the overall situation of the current blockchain. In the initial state, there is only one block.
3. Deploy and use smart contracts
Next, the editor will teach you how to deploy and use smart contracts on your own blockchain.
Under the Smart Contracts tab of the smart contract management panel, 2 smart contracts are listed as examples, namely map and chaincode_example02. The map contract can implement key-value pairs (key-value), the chaincode_example02 contract can simulate transfers and inquiries between two people.
Editor's note: The codes for these two sample contracts can be found in the Hyperledger Fabric source code.
Take the deployment and use of the chaincode_example02 contract as an example:
Deploy the contract
Click the Deploy button corresponding to the chaincode_example02 contract, and fill in the initialization value of the contract, including the contract name, initial function, and initial parameters. The initial function of the contract is init, and the initial parameters need to be filled in according to the format, such as ["a", "100", "b", "200"], which means registering two people a and b, giving them 100 units and 200 units respectively.
Click the Deploy button and the contract will be deployed in your blockchain. The process will take about 20 to 40 seconds. When a new block appears on the blockchain panel, it usually means that the contract has been deployed.
Call the contract
After the deployment is completed, view the deployed contract instance under the My Deployment tab of the smart contract management panel.
Click the Invoke button below the Action to call the smart contract, and fill in the called method name and corresponding parameters (the method names and parameters of different contracts have different meanings, which are related to the content of the contract). For this contract, call the invoke method name and fill in the parameters ["a", "b", "50"], which means a transfers 50 units to b.
After clicking Submit to complete the call, you can view the blockchain situation and a new block will be generated.
Query Contract
After the call is completed, you can query the contract execution results. Still under the My Deployment tab, click the Query button under Action to query the smart contract, and fill in the query method name and corresponding parameters. If you select the query method name and fill in the parameter ["a"], it means querying the current unit of a.
After clicking Submit, you can see that the current unit of a is 50. You can try query b again!
OK, then you can continue to operate the contract, observe the blockchain situation, or deploy a new smart contract, such as map, on the blockchain. For ease of use, the method names and parameter formats for deploying, calling, and querying contracts are all filled in by default. You only need to select a method name and change the parameters as you like! See how long you can play with the chain~
4. Upload and test your own private smart contract
In addition to the two public smart contracts currently provided, you can also upload and test your own private contract! Private contracts can only be seen by you.
Click Import priv under the Smart Contracts tabate smart contract.
After filling in the contract name and description, and uploading the contract code file, click Import to complete the upload.
Then the contract I uploaded will appear in the Smart Contracts list and can be deployed, called and queried as before.
