⑴ How can blockchain + Internet of Things be combined

Before the “Internet of Things”—billions of people silenced everyday items such as refrigerators, door latches, and lawn sprinklers. A recent IBM report titled "Device Democracy" concluded that it would be impossible and unwise to centrally track and manage these billions of dollars of devices; such an attempt would leave them vulnerable to hackers and Government supervision. Distributed registers seem like a good choice.
The Internet of Things uses blockchain as a communication bridge between things. In order to achieve this, we can use the programmability provided by
Ethereum, not only to allow people's property to be tracked and registered . It has some new uses. Under various method rules, car keys embedded in the Ethereum blockchain can be sold or rented, creating a new P2P for renting or sharing cars. Going further, some people talk about applying this technology to make self-driving cars a public resource for society. According to preset program rules, such vehicles can themselves store some digital money to pay for their rental fuel, maintenance and parking spaces.

⑵ What is the Internet of Things, what is blockchain, what is big data

The development of blockchain to this day has extended from the initial financial transactions to all transactions that require intermediaries for guarantees Or certified application projects, such as house transactions, car sales, etc., can even integrate blockchain technology with other application services through API connection, thereby accelerating the production of various innovative applications, and even helping Accelerate the development of Internet of Things applications.

The earliest application of blockchain is Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. It is like a database ledger, and the ledger also contains data from Bitcoin. All transaction records since then include multiple block records. Each block corresponds to a part of the transaction and records the hash value of the previous block, forming a chain-like data structure.

Many experts believe that the emergence of blockchain technology solves the missing link in the security, privacy and reliability issues of the Internet of Things. It can be used to track billions of interconnected devices, facilitate transactions and collaborative processing between devices, and save a lot of costs for the IoT industry. This decentralized approach will eliminate single points of failure and create a more reliable of devices running the ecosystem. At the same time, the encryption algorithm used in the blockchain can also bring higher privacy to consumer data.

The advantage of the blockchain is that it is public, and every network participant can see the blocks and the transaction information stored in them. However, this does not mean that everyone can see your actual transaction content, which is protected by your private key.

Blockchain is decentralized. There is therefore no single authority that can approve transactions or set special rules for their receipt, which means there is a huge amount of trust between participants, so all network participantsConsensus must be reached to receive the transaction.

The more important point is that the blockchain is very secure. This kind of data can only be continuously expanded, and previous records cannot be changed. And the ledger used by the blockchain is tamper-proof and cannot be manipulated by criminals. This ledger is not located in a specific location and cannot be attacked on middlemen because no single communication thread can be intercepted. .

Blockchain can be applied to the Internet of Things to ensure information security. For example, manufacturers of equipment and instruments can use blockchain technology to trace back the manufacturer, production date, manufacturing batch number and even the manufacturer of each component. Other information about the manufacturing process to ensure the transparency and plasticity of the entire machine production process, effectively improve the availability of the overall system and components, and thereby ensure the safety of the operation of equipment and instruments.

The unique consensus mechanism of the blockchain connects various devices through a point-to-point method, rather than through a central processor. Each device maintains consensus and does not require central verification, thus ensuring When a node has a problem, it will not affect the overall data security of the network.

Now, as blockchain technology continues to develop and heat up, Shenzhen Beihang Internet of Things Research Institute (www.buaaiot.org) believes that it will also change and integrate into various fields in its own unique way. industry. The birth of blockchain technology has made various algorithms more efficient. Its decentralized principles and distributed computing rules allow everything to be connected and calculated in seconds, and prevent hackers from attacking data. All kinds of assets can be realized in the area. Registration, transactions and data on the block can never be tampered with or reversed. This intangible charm allows various assets to gather on the block.

⑶ The implementation of the "Blockchain + IoT Security" international standard led by Changhong empowers smart home applications to accelerate

Recently, organized by IEEESA (International Electrical and Electronics Engineers Standards Association) The global standards project meeting 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 blockchain-enabled IoT security work under the IEEEC/BDL Computer Association Blockchain and Distributed Accounting Standards Committee.The first standard proposal launched by the group.

“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 threshold and application cost of the Internet of Things security system, and break through the key bottlenecks in the industry's technological innovation and application development." said a relevant person from Changhong Holdings.

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 harm to the entire Internet of Things. Big damage. The distributed network structure of the blockchain allows devices to maintain consensus without the need for verification with the center. In this way, even if one or more nodes are breached, the data of the overall network system is still reliable and safe.

"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." 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 traditional boundaries. The security model is being challenged. The interconnection between heterogeneous and heterogeneous master 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 a large number of security and trust challenges in the Internet of Things to realize the Internet of Things. End-to-end security and trustworthiness.

"Breaking the original isolated individuals, blockchain + IoT technology can realize a distributed collaborative network. Connect various smart home manufacturers, home appliance terminal platforms and regulatory agencies in the form of blockchain nodes , realizing the true interconnection of all things, solving key bottlenecks and core pain points, and also enhancing the prosperity and compatibility of the smart home ecosystem." said Hong Shibin, founder of Yuecheng Co., Ltd.

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 in a future of 'Internet of Everything'" , is very necessary. The launch of the standard 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 grow 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 global standards. The first '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 them.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. Construction-wise, its awareness has grown. " 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. , becoming an important support and even a leader, it is showing 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 ubiquitous in future production and life. 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.

⑷ The role of blockchain in the field of Internet of Things

To reduce operating costs, blockchain technology focuses on point-to-point direct connection. way that data is passed through instead of going through the central processing unit. To reduce security risks, the core problem of IoT security lies in the lack of original mutual trust mechanism between devices. Efficient and intelligent network operation mechanism. Since the blockchain has decentralization and consensus mechanism, on the Internet of Things, cross-system data transmission will be transferred from the upper layer to the underlying blockchain.
The combination of blockchain technology and the Internet of Things can eliminate the audit and certification links between nodes, directly build a communication bridge for multiple parties, and improve network operation efficiency. At the same time, the decentralized consensus mechanism based on blockchain can also ensure the security and privacy of the Internet of Things and facilitate the transmission of real information. In view of this, blockchain and the Internet of Things will truly come together and play the strongest voice of the Internet of Everything.
Hongqiao Hi-Tech’s blockchain industry-specific application design uses the integrity and correlation of trusted transaction data to form a closed-loop self-certification capability for data on the chain. Used to verify the authenticity of digital documents and transaction records, and to track the origin of products and merchandise throughout the supply chain. This data proving product authenticity and origin is generally used by businesses and financial institutions in the assessment and processing of credit and loans.

⑸ What are the applications of blockchain technology in the Internet of Things

The application of blockchain in the Internet of Things can mainly solve the following problems: solve security risks, protect user privacy; reduce the risk of the Internet of Things operating costs.
In fact, there are many specific applications, but they are all in the process of development and research and development. It can be said that blockchain technology is still not mature. Among many companies, Yingtang Zhongchuang has developed more applications of blockchain technology, which has a certain impact on the future development of the Internet of Things.

⑹ What are the application prospects of blockchain in the Internet of Things and logistics fields?

Blockchain is the most commonly used in the financial field, and the one that has been favored in the past two years is Logistics field, because the logistics field has long been complex and difficult to standardize, the emergence of blockchain can gradually solve these problems, such as paperless transmission of information, such as removing intermediaries, visual tracking of goods throughout the process, digital asset management, insurance claims, Intelligent reconciliation, industry blacklist sharing, etc. Currently, I have just joined a company called Yunliu Blockchain, which mainly applies blockchain technology to the shipping and logistics industry. The initial solutions are paperless order processing, cargo tracking, and fleet network.Issues such as submitting dispatch orders.

⑺ What are the challenges in the application of blockchain technology in the Internet of Things?

What are the challenges in the application of blockchain technology in the Internet of Things
Blockchain in the Internet of Things Challenges in networking include but are not limited to the following three points:
1. The deployment and implementation of blockchain are jointly participated by multiple nodes, but the storage and computing capabilities of IoT nodes have certain limitations. Therefore, the deployment of blockchain technology in IoT nodes, whether the blockchain architecture is hierarchical, and issues that need to be strengthened in existing blockchain technology all need to be taken into consideration.
2. The Internet of Things will be real-time, and the blockchain consensus mechanism generally has delay problems. Therefore, consensus delay may cause feedback delay and alarm delay, which cannot meet the needs of existing IoT applications and requires further technical improvements.
3. The current application of blockchain in the Internet is only carried out within a certain range and limited nodes. Once blockchain is applied to the Internet of Things, the number of nodes will increase exponentially, and its frequent relational data query requests will pose a very severe challenge to the existing chained data architecture.
In today's society, new technologies and industries are emerging around the world, and network technology is being transformed into productivity at an unprecedented speed. The development prospects of the Internet of Things are broad, but it faces many historical opportunities and challenges; the application of blockchain in the Internet of Things can, to a certain extent, solve the problems and new needs faced by the Internet of Things.

⑻ In what aspects is the application of blockchain technology reflected?

Blockchain has become popular, so what are the application fields of blockchain?

At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency.

Financial institutions are the most willing to explore blockchain applications and need new technologies to improve operational efficiency and reduce costs to cope with the current status of the entire global economy. Objectively speaking, the market space in the financial industry is huge, and a little progress can bring huge benefits. The financial industry is an industry with extremely high requirements for security and stability. If the application of blockchain in the financial field is verified, it will have a huge demonstration effect and be quickly promoted in other industries. In the financial field, in addition to digital currency applications, blockchain has gradually begun to be applied in cross-border payments, supply chain finance, insurance, digital bills, asset securitization, bank credit reporting and other fields.

As the application of blockchain technology in the financial field continues to be verified, its technical advantages are gradually showing value in other industries. At present, blockchain application projects are gradually being implemented in fields such as medical and health, IP copyright, education, culture and entertainment, communications, charity, social management, sharing economy, and the Internet of Things, and "blockchain" is becoming a reality.

(1)Blockchain medical treatment: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health (EHR), DNA wallet, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.

(2) Blockchain Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the Internet of Things with blockchain technology Application will become a very important application field.

(3) Blockchain IP copyright & cultural entertainment: Since the Internet became popular, digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry. Blockchain has the characteristics of disintermediation, consensus mechanism, and non-tampering. Blockchain technology can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time, the value of digital content can be realized Transfer, and ensure that the transfer process is credible, auditable and transparent, effectively preventing piracy and other behaviors. Blockchain Public Services & Education: In the fields of public services, education, closed-door charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. The traditional method is to rely on third parties with credibility. The company makes credit endorsements, but problems such as fraud and deficiencies still exist.

⑼ Is the large-scale application of blockchain in the Internet of Things an inevitable trend? What do you think?

Blockchain technology can be applied in many industries. However, blockchain technology is still developing. Just like the early Internet, some speculators will fish in troubled waters, but I believe that the development of blockchain technology will make people's lives more convenient.
The application of blockchain + Internet of Things reminds me of a project called INT that I paid attention to before. The direction is the same, and the opportunity for implementation is quite large. You can learn more about it.
In addition, not only the Internet of Things, but also in the field of social e-commerce, the application of blockchain technology is more convenient, and SEC social e-commerce chain is one of them. The SEC project has rapid development dividends across the two fields of blockchain and social e-commerce. The market share of social e-commerce continues to expand, growing at a rate of more than 50% every year. The number of employees working on WeChat alone has exceeded 36 million, and the number of consumers exceeds 200 million. SEC has the opportunity to become one of the applications with the most users, and its potential business value is immeasurable Estimate.
