⑴ The future development prospects of blockchain will profoundly affect three aspects

It is still unknown how much technological impact blockchain will bring to the human world, but industry, academia and research generally believe that , currently we have only seen the tip of the iceberg of the potential value of blockchain! Blockchain technology will not only change technology and reshape industries, but will also shake the existing order, traditional rules and value systems of human society. As blockchain technology gradually matures, it is foreseeable that blockchain will show the following development trends.

Zero-knowledge proof

Blockchain is very transparent in nature. Any node running in the blockchain network can view and download all data stored in the ledger. Blockchain combines zero-knowledge proof technology to allow users and businesses to use private data to execute smart contracts without revealing specific data content.

Artificial Intelligence

Blockchain can serve as the foundation for decentralized markets and a coordination platform for various artificial intelligence components, including data, algorithms, and computing power. This could lead to new levels of innovation and use of artificial intelligence. Blockchain will also make such decisions more transparent, explainable and trustworthy. Since all data on the blockchain is public, artificial intelligence will become the basis for providing anti-counterfeiting and privacy protection.

Internet of Things

Blockchain can add a layer of accountability and security to IoT data, becoming the future driver of IoT efficiency, scalability and standardization By. For example, in healthcare, blockchain-enabled IoT devices will allow patients to control access to the data collected by these devices. This technology will make devices more resistant to cyberattacks and provide a detailed record of when another party accessed data. In supply chains, blockchain-based systems, powered by smart contracts, can automate payments based on specific conditions measured by IoT sensors.

The arrival of the blockchain era has revealed the future development trends of various industries, and the increasingly mature technology of blockchain has gradually entered a period of expansion. I believe that in the near future, it will definitely produce greater economic benefits for society.

⑵ How can blockchain + Internet of Things be combined?

Before the “Internet of Things”—billions of people silenced daily necessities 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. Ethereum blocks embedded in car keys under various ruleshain, 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.

⑶ The role of blockchain in the field of Internet of Things

To reduce operating costs, blockchain technology focuses on transmitting data through point-to-point direct connection rather than through central processing device. 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.

⑷ You have to know the operating principles and development of blockchain!

1. Why is there innovation in blockchain?
The starting point of the first generation of the Internet is the TCP/IP protocol, which implements a unified format for peer-to-peer transmission of information by all nodes on the network. Open code. However, the impact of such an uncomplicated innovation on mankind is epoch-making. It has programmed, agreed, and enforced the basic values ​​required by a unified global market: "freedom, equality, and fraternity." Then the STMP email protocol, HTTP domain name protocol, etc. were derived, achieving low-cost and high-efficiency global information transmission in a decentralized manner. As Alibaba Vice President Gao Hongbing said:
"The Internet is to eliminate the (information) supply chain that has very low value and high cost - it is open, interconnected, peer-to-peer, globalized, and decentralized."
We know: The essence of the market is also decentralized. It automatically executes the decentralized agreement of "equivalent exchange". Just as Nobel Prize winner Ronald Coase summed up: "The market economy is based on two On the basis of deep cognition: admitting ignorance and tolerating uncertainty." Adam Smith also described the market as: "the invisible hand"! Therefore, the market must require the low-cost flow of information decentralization, and the Internet has adapted to the global Under the general climate formed by the unified market, it turned out to be.
However, the first generation of Internet decentralized solved the problem of low-cost and efficient transmission of information, but it did not solve the problem of credit of information. Therefore, what the second-generation Internet must break through is: how to establish global credit in a decentralized manner so that value transfer can be carried out at low cost and with high efficiency.
So what are the problems with the original centralized credit system? As we all know: centralized credit, such as the legal currencies of various countries, has different credit values, and the clearing systems are also incompatible, which adds a lot of cost to global trade. The current global credit system centered on the US dollar has a "Triffin Paradox" in its mechanism (the essence is that a country's legal currency cannot simultaneously resolve the conflict between its own economic interests and global economic needs). Therefore, in 2009, the Governor of the Central Bank of China, Zhou Ogawa called for the creation of a super-sovereign storage currency. In the same year, Satoshi Nakamoto disclosed the first-generation blockchain source code-"Bitcoin" online.
2. How does the blockchain system operate?
First of all, Satoshi Nakamoto knew very well that establishing a credit system for payment must solve the problem of preventing "duplicate payments", that is, no counterfeit currency can be created. The centralized credit system relies on state machinery to prevent counterfeit currency. What about "Bitcoin"? Satoshi Nakamoto's great innovation is to "timestamp" every transaction. There is a block (block: equivalent to a network account book) every ten minutes, and all network transactions for these ten minutes are correctly timestamped. The question is who will cover it? Satoshi Nakamoto did not assume that everyone on the Internet is Lei Feng. He agreed with Adam Smith: people in the market are greedy. He asked the so-called "miners" to compete for the accounting rights of these ten-minute blocks. The rules of the competition were to correctly record the accounting and at the same time solve the SHA256 problem. Who can prove that their computer has the fastest computing power (the so-called PROOF OF WORK mechanism), he can compete for the legal accounting rights of these ten-minute blocks and get a reward of twenty-five bitcoins. This is the so-called "mining" process. It is actually a decentralized credit process that establishes a network-wide ledger - the blockchain. Therefore, the more essential function of miners is "bookkeepers"!
Satoshi Nakamoto is here In its Bitcoin white paper, the process of establishing this credit system is described in detail:
Step 1: In order for the entire network to recognize it as valid, each transaction must be broadcast to each node (node: that is, the miner);
The second step: Each miner node must correctly timestamp each transaction in these ten minutes and record it in that block;
The third step: Each miner node must Compete for the legal accounting rights of this ten-minute block by solving the SHA256 puzzle, and strive to get a reward of twenty-five bitcoins (fifty bitcoins every ten minutes for the first four years, decreasing by half every four years);< br>Step 4: If a miner node solves the SHA256 puzzle of these ten minutes, it will publish all the timestamped transactions recorded in its ten-minute blocks to the entire network, and they will be checked by other miner nodes in the entire network;< br>Step 5: Check the area with other miner nodes in the entire networkThe correctness of the block accounting (because they are also stamping the accounting at the same time, but they have not competed for the legal block accounting rights, so there is no reward). If there is no error, they will compete for the next block after the legal block. , thus forming a legal accounting block single chain, which is the general ledger of the Bitcoin payment system - the blockchain.
Generally speaking, each transaction must undergo six block confirmations, that is, six ten-minute accounting, before it can finally be recognized as a legal transaction on the blockchain. The following is the accounting format of Bitcoin:
So the so-called "Bitcoin" is such a billing system: it includes the owner electronically signing with the private key and paying to the next owner, and then the entire network's "miners" "Time stamp the account and form a blockchain.
3. What are the innovations in Bitcoin’s blockchain finance?
Similar to gold, trying to establish decentralized credit on the global Internet may allow value to flow across the entire network at high speed and at low rates (currently each transfer The transfer rate is one ten thousandth);
The total amount of currency is agreed upon by the cryptographic protocol;
Compared to gold, digital currency is infinitely divisible;
The value of currency can be based on a large number of P2P transactions ;
Full transparency in financial management (every transaction can be traced on the blockchain).
Bitcoin’s blockchain-wide accounting system has established a market value of US$10 billion, the highest on the global Internet. Therefore, Wu Xiaoling, dean of Tsinghua PBC School of Finance, pointed out: The blockchain experiment established distributed credit, which is an upgraded version of Internet TCP/IP, upgrading from information transmission to value transmission;
4. Bitcoin’s blocks What are the inherent flaws of the chain system?
Bitcoin’s blockchain system has had successes since it was open sourced on the Internet in 2009, but it also shows some inherent flaws that are difficult to overcome:
The total amount cannot be adjusted at any time As the market situation changes, it will inevitably rise and fall sharply;
Mining is high-carbon. Only less than 1% of miners can compete for the accounting rights of blocks of less than ten minutes, and more than 99% of other miners participating in the competition have the computing power. Waste;
The annual inflation of about 10% has greatly increased the cost of the Bitcoin financial ecology, and even threatened her survival;
As a decentralized self-organizing DAC system, the operating costs of the accounting and issuance functions are too high high.
As a global payment system, its efficiency is far from meeting the actual requirements of global trade. The Bitcoin network currently confirms a maximum of 7 transactions per second. In comparison, Visa's network system can process 10,000 transactions per second at the fastest, and Alipay's record is 80,000 transactions per second on Singles' Day in 2014!
5. Block The development of chain technology 2.0:
As the 2.0 upgrade and development of blockchain, it first focuses on solving the high-carbon mining of Bitcoin accounting:
When we discuss how to overcome the high carbon of Bitcoin mining and accounting Professor Liu Taoxiong from the Tsinghua Institute of Economics pointed out that mining competition relies on computing power. In the end, only one company competes for the legal accounting rights, and the other 99% of the miner nodes are mined for nothing, which is a waste of resources.Although it is unreasonable, if the entire network transparently knows the legal accounting rights of the next block and randomly generates them in the entire network, it will eliminate the high carbon cost of competitive accounting! After hearing this, we all praised Professor Liu for his brilliant idea, because The current relatively successful second-token NXT has exactly this mechanism. Their white paper is called "Transparent Forging". However, the probability of who gets the accounting rights is directly proportional to the NXT token holdings in each miner's node wallet. This is called PROOF OF STOCK. Of course, this also triggered a debate about the unfairness of NXT’s distribution of tokens to early investment developers!
RIPPLE is a semi-decentralized blockchain solution that uses “trusted gateways” to conduct block operations. The credibility of chain accounting is based on the consensus ledger protocol that these gateways will not do evil at the same time.
The most ambitious attempt is Ethereum, which combines blockchain technology with Turing completeness, hoping to develop a basic platform that can support the construction of various blockchain systems in the future. The development of various credit currencies, digital assets, smart protocols and even financial derivatives. The system design is to unify blockchain accounting on the ETHERUM platform and be used by all developers. Maybe their official version will be released in the near future.
6. Possible applications of blockchain innovation in other fields:
Now, blockchain’s attempts to establish decentralized credit are no longer limited to the financial world, but have attracted attention from all fields of society, especially in At present, some of China's central credit institutions, such as the "Red Cross", are in a "collapse" situation. Blockchain can provide a new way of thinking and technical options for social management. The following are some new developments and related discussions we have learned about:
The combination of blockchain and the Internet of Things unifies digital assets and atomic assets, smooths the difference between consumer assets and cash assets, expands public credit, and accelerates value circulation; (IBM-Samsung)
Built on the blockchain Intellectual property protection system, accounting for the use of intellectual property across the entire network, and establishing a global advertising market;
Whether blockchain can provide technical support for the issuance of protocol-based cryptographic currencies by emerging economies along the Belt and Road;
Block Chain + cloud computing can develop into a decentralized self-media and community system;
Blockchain can build a decentralized equity crowdfunding system, allowing innovative projects to enter the circulation field in advance;
Blockchain can develop Develop a fully transparent financial management system;
Blockchain supports the establishment of a global decentralized corporate organization.
In short, in this era when credit has become a scarce resource, the technological innovation of blockchain, as a distributed credit model, provides new opportunities for finance, social management, talent evaluation and decentralized organization construction in the global market. All provide a broad development prospect.

⑸ Talk about the current limitations of the Internet of Things

With the emergence of blockchain technology, although we have moved closer to this futuristic visionMany steps, but still far from the ideal goal. The following is a brief list of some key limitations:

1. Lack of mainstream blockchain networks specifically developed for IoT devices (Note: As of the time of writing this article, there is no blockchain The system can be called "mainstream");

2. Equipment manufacturers have not yet embedded encryption keys into all hardware, nor have they established compatibility with blockchain as a common standard ;

3. Software encryption methods used to ensure privacy protection algorithms are extremely inefficient and impractical [1], while hardware solutions need to be based on complete trust in the manufacturer and the entire manufacturing supply chain. on the basis of. Therefore, it is difficult to prevent data piracy;

4. Artificial intelligence is not sophisticated enough to achieve this highly autonomous decision-making behavior in devices;

5. In order to further To eliminate on-chain transaction risks, corresponding legal means need to be established, but only limited countries and regions [2] recognize that on-chain smart contracts have the same legal binding force as off-chain contracts.

But even with these limitations, blockchain still has the potential to provide a wide range of value-added applications and can solve many technologies facing the Internet of Things. First, let’s take a deeper look at the current progress of blockchain technology and what we can do to improve the current state of the art.

Blockchain network developed for IoT devices
Considering all the synergies between blockchain and IoT, a blockchain network that can perfectly adapt to the needs of IoT What characteristics will it have? While many blockchain technologies are foundational in nature and not explicitly focused on a specific application, at the public ledger level there are many design and optimization choices that reflect the application stack that designers had in mind during development .

Characteristics of IoT devices and their impact on blockchain network design

When talking about IoT, especially running it on existing blockchain networks When comparing nodes, we need to be clear: all current blockchain networks rely on powerful and always-connected servers to perform all record-keeping and consensus tasks. It is now obvious that the restricted and unique characteristics of most of what we think of as “Internet of Things” devices, or smaller, sometimes mobile, connected devices are not ideal for this scenario.

The term "IoT" is basically used to refer to any device connected to the Internet. We can make some summary statements about the characteristics of these devices:

Big Scale: [3] According to some statistics, the number of IoT devices has exceeded the world’s population and will continue to grow at a faster rate;

Limited computing power: [4] Even with Compared with the processing power of ordinary laptops, the computing power of IoT devices is often not comparable in magnitude.No.;

Limited storage space: The original intention of most IoT devices is not to store information locally, but to simply relay information (such as uploading to the cloud), so their storage space is very limited;

Limited bandwidth and network connectivity: Many IoT devices operate in wild environments without reliable network connections, where networking costs are high (e.g., satellite networks deep in the woods);

Energy consumption limitations: Many IoT devices run on batteries or through energy harvesting mechanisms, which severely limits their energy consumption.

So if you want to design a blockchain network that is most suitable for IoT devices, what key indicators need to be met?

1. The network needs to be scalable: Considering that there may be billions of devices connected to any given blockchain network, the network must be able to expand its ability to process transactions and requests.

2. The network needs to support the discovery and transaction of general assets: There are many tradable digital assets and resources (such as data) on IoT devices, not just currency. So there is also a need for ways to discover these assets.

3. The network needs to support selective storage: Considering all the limitations of IoT devices, they will only be able to participate in a small subset of the network, and the storage and storage of each device must be carefully selected. Processed content.

4. The network cannot rely solely on "working" to maintain security: Network security cannot be based solely on solving complex cryptographic problems, which will make it difficult for IoT devices to perform blockchain transactions.

5. The network needs to support trustless light nodes: Current IoT devices are not sufficient to support the operation of full nodes, but they still need to maintain their independence on the blockchain network, so in "Light" nodes running on IoT devices cannot be naive (i.e. blindly trust another full node) and should have some way to verify network status and state transitions.

6. The network needs to support point-to-point transactions: Many transactions between IoT devices are highly localized, that is, the devices are adjacent to each other, and it is impossible to wait for the delay caused by the verification of the entire network every time. .

In summary, even though there are still many limitations in the current combination of blockchain and IoT, on the basis of meeting the above key indicators, it is possible to design a blockchain network that is most suitable for IoT devices. , to better empower the IoT ecosystem.

⑹ What are the differences between blockchain and the Internet of Things

Internet of Things technology allows tangible objects used daily to be connected to the Internet, transmit data through algorithms, and better serve Customers provide services. The most intuitive manifestation of the current rapid development of IoT technology is the proliferation of smart devices such as televisions, furniture, and vacuum cleaners. Currently, there are already smart homes that are entirely operated by built-in algorithms.

Blockchain is a distributed data storage, point-to-point transmission, consensus mechanism, encryptionNew application models of computer technology such as algorithms.

The distributed nature of blockchain means it is resistant to most security issues. Blockchain systems’ advanced encryption provides better protection against hackers than traditional client-server systems. This is why online transactions using virtual currencies are very safe.

⑺ Energy Blockchain Research | The Internet of Things can improve the efficiency of cryptocurrency mining

Everyone who understands cryptocurrency knows the shortcomings of this currency, and its impact on the environment bear the brunt of the impact. Is it possible to mine cryptocurrencies in a green and ethical way? If so, what role will the Internet of Things play in this shift?

Can the Internet of Things be mined?

People started discussing using the Internet of Things for cryptocurrency mining a few years ago Mining, these discussions have mostly come in the form of warnings that bad actors could compromise an IoT device and turn it into a distributed cryptocurrency mining network.

Cryptocurrency mining requires powerful central processing units and consumes a lot of energy. Can IoT devices be used to mine cryptocurrency?

Mirai is a household name in the cybersecurity world, but the term is often synonymous with DDoS attacks. IBM's investigation in 2017 found that subsequent Mirai cyberattacks were designed to deploy Bitcoin miner slaves on compromised IoT devices. IBM didn't draw specific conclusions about the effectiveness of leveraging IoT devices, but the concept is intriguing.

Are there other ways IoT, cryptocurrencies, and blockchain can impact each other’s performance?

Impact of IoT on Cryptocurrency Mining

In Not long after IBM's discovery came out, Avast came to a similar conclusion: This kind of use of the Internet of Things was not only possible, but profitable. Avast estimates that an attacker could mine approximately $1,000 worth of cryptocurrency in four days using 15,000 IoT gadgets simultaneously.

Using thousands of cryptocurrency mining rigs can reduce the overall power consumption and environmental impact of a single cryptocurrency mining operation. There’s an anecdote about a tech blogger who set up and forgot her IoT devices, only to find them generating thousands of dollars worth of tokens in the background for over a year.

Using routers and hotspots as network hubs and cryptocurrency mining hubs has a bright future because it’s about efficiency and being green. After this person wrote about her experience, orders for related hotspot devices rose to 150,000 units. Compared to expensive CPUs and GPUs, the $400 price tag of this hotspot device is attractive to amateur miners who don’t want to spend a lot of money on cooling systems and graphics cards.

Technologies that make mining more environmentally friendly

Making cryptocurrency mining more environmentally friendly is not an easy task. Single transactionBitcoin transactions consume approximately 1,544 kilowatt hours of electricity, which is enough electricity to power an average American household for more than fifty days. The total annual electricity consumption of the Bitcoin network may be as high as 75 terawatt hours.

Smarter climate control technology is one solution. Mining operations can have more granular control over their environment with ductless and mini-split systems. It is much easier to place these units exactly where they are needed, and one outdoor condenser can power multiple cooling units. These devices can save cryptocurrency miners a lot of energy.

As it stands, electricity is a major bottleneck restricting cryptocurrency mining. National and international leaders have prioritized building resilient smart grids in setting goals that rely on the Internet of Things to enable the two-way flow of power and data.

Building energy networks that use renewables and the Internet of Things to be more resilient and performant opens up opportunities for cryptocurrency miners. Some of the larger operations are opening factories in areas rich in solar and wind energy. Other miners work at night to offset the huge impact their operations have on energy consumption during peak electricity usage hours.

Take a mining operation in Texas, for example, that can profit from energy consumption by shutting down for just 30 minutes at a time during its hottest and most expensive days. At night, they can "operate as little as the board can handle" while selling back the contracted power supply to the utility company.

Blockchain and the Internet of Things: A fruitful combination

The Internet of Things and cryptocurrencies have found the right way to complement each other and complement each other. The combination of IoT and blockchain may bring fruitful results, and research and discussions around this topic are proceeding in different ways.

IoT devices rely on high-speed exchange and analysis of field data. Applying blockchain here ensures greater reliability of the system and greater security of data transmission. Autonomy is critical for business efficiency: with blockchain driving IoT interactions, devices can interact directly with each other without involving remote servers.

The technologies used in IoT and cryptocurrency respectively complement each other and bring out the best in each other.

⑻ What is 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 application projects that require intermediaries to guarantee or authenticate, such as house transactions, Car buying and selling, etc., can even integrate blockchain technology with other application services through API connection, thereby accelerating the creation of a variety of innovative applications, and even helping to accelerate the development of IoT 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 the receipt of transactions. This means that there is a huge amount of trust between participants, so all network participants must reach a consensus to receive transactions.

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. The registration, transactions and data on the block can never be tampered with or reversed.The charm of the shape allows various assets to gather on the block.

⑼ Blockchain will change the world in ten years. LinkToken will take you to see it

The blockchain era is coming | What new applications will there be in the new year?

If recent research is to be believed, we are likely to see real-world applications of blockchain technology within the next two years.

Recently, HackerRank, a well-known technology recruitment company, released the "2019 Developer Skills Report". Among the 71,281 developers who participated, more than 23% said that the actual application of this technology in the next 24 months will still be Very possible.

About 27.54% of people think this is more realistic, 21.89% are not sure, 19.77% think the technology has been exaggerated, and only 7.01% think it is unrealistic.

Internet of Things

However, don’t be too busy to be happy. To pour cold water on it, the report predicts that compared to blockchain, the Internet of Things (IoT) will be the future The most popular technology of the year.

Developers believe that unlike blockchain, which is still in its infancy, IoT adoption is driven by increasing connectivity between homes, cars and cities.

How to achieve it

Blockchain technology is increasingly being tried and tested by mainstream institutions in many industries, but the technology does not seem to be available yet Stand firm.

Banks appear to be particularly interested in blockchain because private decentralized ledgers may bring greater efficiency and lower costs, especially in stock trading and clearing.

This technology also has great potential in related fields such as health care, where it can be used to combat the trafficking of counterfeit drugs.

Traditional energy companies are also actively exploring. In fact, Spanish multinational electrical company Iberdrola recently completed a blockchain trial aimed at tracking renewable energy more efficiently.

If these experiments and tests don’t translate into real-world applications, we may see an increase in the number of developers who think blockchain is overhyped if we take another look at it this time next year. .

⑽ Blockchain technology realizes full-process visualization of the supply chain

Blockchain essentially solves privacy and security protection, information traceability, transaction compliance, data authenticity and The process handles efficiency issues and directly addresses the difficulties of supply chain management. It has strong applicability and application value in supply chain scenarios.

Data sharing: Through information encryption and decryption authorization, zero-knowledge proof and other privacy protection mechanisms, blockchain can solve the long-standing contradiction between data privacy and data sharing value, and eliminate the concerns of relevant parties in data sharing. No worries;

Data traceability and qualification assurance: Blockchain is a traceable block chain data structure built in a peer-to-peer network environment, which has the characteristics of data traceability and prevention.Counterfeiting and tampering characteristics ensure the authenticity and traceability of data across the entire chain (including supply chain status information and related enterprise qualification information, etc.). True and traceable data will become an important foundation for product anti-counterfeiting, supply chain management, supply chain finance and other business development;

Currently, blockchain technology is mainly used in four representative scenarios in the supply chain field: (1) Traceability and visualization (2) Supply chain collaboration (3) Logistics process optimization (4) Supply chain finance.

Blockchain + IoT technology can realize full-chain visualization of the supply chain. Among them, the characteristics of blockchain technology such as distributed storage, non-tamperability, and consensus mechanism ensure that the storage and circulation of key data of relevant parties are authentic and trustworthy. The Internet of Things technology can ensure the comprehensiveness of the on-chain data and its authenticity and reliability. The combination of the two jointly improves the coverage and authenticity of data in the upstream and downstream of the supply chain.

As an enterprise-level blockchain service platform, Jiamu Technology is committed to building a more secure and stable blockchain environment for customers, simplifying deployment, operation, maintenance and development processes, and achieving rapid business on-chain.

Both upstream and downstream companies in the supply chain, as well as consumers and regulators, will benefit from this supply chain visibility. Jiamu Technology believes that for upstream and downstream companies in the supply chain, having a complete product traceability system has become a crucial and differentiated success factor for relevant companies to respond to consumer demand.

For example, in the fresh food industry, fresh food manufacturers and retail companies can accurately control the temperature, humidity and storage time of each link through blockchain + IoT. By combining the three-party data of inventory, logistics and shelves, Through analysis, the real fresh product consumption situation can be fed back to the upstream of the supply chain, optimizing the procurement rhythm and purchasing decisions, timely adjusting inventory levels and turnover rates, effectively carrying out distribution at the distribution end, and reducing product losses. Thereby optimizing inventory management, improving the quality of fresh products, and gaining favor from consumers.

For consumers, they can scan the traceability code to realize the full-process traceability of goods down to one item and one code, and easily read product quality information. For regulatory agencies, in the context of the country’s increasing requirements for commodity safety supervision, blockchain + IoT provides the necessary technical support to improve supervision efficiency and accuracy.

At present, commodity traceability technology based on blockchain and the Internet of Things has been implemented in many scenarios such as food traceability and drug traceability. Large consumer goods manufacturing companies, retailers, and government regulatory authorities are actively involved in related blockchain construction.

Blockchain rowThe promotion of industry-level applications is inseparable from people's deepening understanding of blockchain technology. Jiamu Technology actively promotes the implementation of blockchain technology, pays close attention to the development of the industry and actively sorts out industry trends. Driven by favorable policies, more companies will participate in the construction of the blockchain landscape in the future, conduct innovative research and work together in the research and development of underlying technology, promotion of application scenarios, and cultivation of industrial ecology to jointly build blockchain prosperity. picture.
