㈠ My husband wants to get rich by doing things like blockchain, is this realistic?

Your husband has the same idea as me, because I lost money in blockchain. 700,000. Later, because my wife stopped me, I started working again, but after working for two years, I found that the bank loan could not be repaid. Now my idea is to get into the blockchain next year, otherwise it will be impossible to pay off the debt in this life! Because for now, only blockchain and the Internet can turn over quickly!

I can tell you clearly that there are three types of people in the blockchain, one is speculating, one is mining, and the other is engaged in technology.

Currency speculation is the same as stock speculation. They are all money-making circles. If your husband has absolute capital to trade, he doesn’t need too much, tens of millions can trade, and there is no Moutai. The market cap is high, but this is very unlikely. Moreover, most of your husband is engaged in retailing, and the other half is engaged in mining.

The second type is to buy a mining machine for mining, which has a payback period and also follows the rise and fall of the currency. If one day this coin becomes worthless, you may lose money.

There are very few people doing the third type, and they are rarely seen online. They can actually put blockchain applications into practice. Blockchain has great prospects, and its characteristic is decentralization. Compared with traditional centralization, large-scale micro-nodes are used to replace high-voltage single-point clusters, which is what we often call the three stooges. Even Taobao dare not say that there will be no problems during Double Eleven. The peak will be busy, and the Alipay server was down two days ago, and requires high costs to maintain. These are the drawbacks of traditional central servers. Blockchain can solve this problem, load sharing, and giant The tasks are divided into very small tasks for corresponding blocks to process. If we encounter the traffic peak of Double Eleven, then congratulations to the miners, they will make a fortune, haha, so there will definitely be more mining machines to mine, that is, to provide The computing power is higher than the peak, and the miners bear the risk at their own risk. Let’s talk about the persistence issue. The amount of storage is getting larger and larger. Even GitHub is complaining. Domestic manufacturers are even more eager to cash in. I believe friends who have done it know that the biggest cost of a file server is not the storage space, but the network bandwidth and bandwidth costs. It is expensive, which is what top manufacturers like Alibaba and Tencent can afford. Blockchain is used for persistent storage. First of all, the network bandwidth problem is solved, and high-bandwidth transmission can be easily achieved. This is the advantage of p2p. High bandwidth can be combined with 5g. Technology, because the advantage of 5g is high bandwidth, they are a perfect match. There are a lot of uninformed self-media people on the Internet talking about the next generation of 5G. . They really don’t understand how to make short videos or something like that. 4G has done a good enough job in those things. 5G will give full play to the advantages of high speed and high bandwidth. To give a few simple examples: storage, blockchain storage can be used in the future. There may not be 64g, 128g, etc., only ram memory, you can specify the size by yourself and pay as you need. Because of the high speed and high bandwidth advantages of 5g, it can completely reach the reading speed of the machine.Second, high-reality VR, because of the distance factor of VR, needs to reach 4k to truly have a sense of immersion, cloud host, and then communicate with VR devices through 5G wireless, without the need for connecting cables and high-end graphics cards like the current HTC devices. , if the application allows, you can even run around the streets with VR glasses, and use virtual reality and augmented reality to simulate what you see based on the real situation, not like the current "elementary school version of ar". . There are many more that I won’t list one by one. In short, the prospects of blockchain are infinite, but its development is hindered due to certain political factors, because blockchain is anonymous, free to speak, and cannot be held accountable.

So if you are a technical person, he will not ask you to invest money without even explaining what blockchain is. If so, he is probably a liar. Coin speculation is not advisable, and mining is not recommended, but blockchain applications are the future. Money is not needed here, but more development talents are needed.

Maybe not many people will understand what I have said, but once you finish reading it, it proves that you are willing to listen. If you agree, it means that you are willing to accept new things and your thinking is not lagging behind. You are not a common person.

We should create the future together instead of being willing to be the dust of time. Live this life and leave some noise

You should be happy to have such a forward-thinking husband. Many people still don’t believe in the blockchain and think it is a scam or a pyramid scheme. At present, the country has Blockchain proves that it is a new economic model that will definitely become popular and develop rapidly in the future! You are not stopping, but investing heavily. This year is the last profit window. Next year, you may not be able to buy a single coin! ! !

To understand this issue, first let’s understand the concept of blockchain.

What is blockchain?

The rise of blockchain originated from the genius idea of ​​a mysterious geek, Satoshi Nakamoto, who invented the world’s first digital currency, Bitcoin. In recent years, the myth of Bitcoin’s wealth creation has made people familiar with blockchain. At the same time, various digital currencies have sprung up. The yearning for wealth has made people also flock to digital currencies.

However, the blockchain itself is not tailor-made for digital currency. Simply put, the blockchain is a decentralized database. To put it more simply, blockchain is a distributed ledger. This ledger does not have a fixed bookkeeper. Instead, when a transaction occurs, everyone keeps accounts together, regardless of whether it is their own transaction or not.

What we need to realize is that digital currency is just a way of blockchain application and does not create value in itself. More importantly, various digital currencies are currently not recognized in our country. , and the central bank is preparing to issue its own digital currency, so if you are investing in digital currenciesI don't think it's a wise choice.

In fact, blockchain as a technology should not be limited to digital currency, but should make a difference in fields such as finance, logistics, insurance, copyright, etc. However, currently blockchain There is still a long way to go in terms of applications in various fields.

If you want to get rich by relying on blockchain, you should think more about the application of blockchain in various fields instead of falling into the trap of digital currency.

I have only come into contact with blockchain knowledge this year, and my understanding must be too little. If you are not engaged in blockchain technology but engaged in blockchain digital currency investment, there is a high probability that you will still lose money in the end.

Judging from your statement, I think your husband must be engaged in blockchain digital currency investment. Even if you are lucky and make some money, you will still lose money in the end. Everyone is saying that Bitcoin has doubled. More than ten thousand times, the appeal of Bitcoin as a benchmark is too tempting.

There are currently thousands of digital currencies, 90% of which are scams and pyramid schemes. The rest have real blockchain technology but may not all be successful. In other words, these Some coins have no value. The only ones with value are mainstream coins such as Bitcoin. When the price of Bitcoin is too high, it can be used as an asset risk investment.

So what should you do?

First, you have to know that it is impossible for your husband not to invest in digital currencies, because he has deeply believed that this is an industry that can multiply thousands of times. Do you think you Is it possible for a person who is doing MLM to leave the MLM industry?

Second, blockchain technology is a good technology and a real revolutionary technology for the future, but digital currency is not a good currency.

Third, your husband likes blockchain. You can support him to learn about blockchain, but you must remember not to invest money in it. The money will be kept for you and you will not invest in it after one year. It will be late. He earns 10,000 per month. If you ask him to invest only 3,000 at most, it will be doubled by tens of thousands. In a few years, he will be able to earn thousands of times.

Fourth, find more news about MLM coins, scam coins, and runaway coins for him to read. There are too many on the Internet, and you can find them all in just one search.

At the same time, this is not the expectation and hope of many family members.

But time is like water, and years are fleeting. We cannot afford to wait for the aging of the elderly and the growth of children. Many men, who are the backbone of the family, are anxious, overworked, and occasionally make mistakes in judgment. Losing your temper is also normal. Long live understanding.

When it comes to getting rich, you should be anxious, but your strategic direction cannot be wrong.

At the same time, with the rectification of the financial industry, many fake blockchain companies that were trying to sell dog meat have also been closed down one after another, and some people have been left empty-handed or jailed.ending.

The most reliable and ultimate application of blockchain can only be to serve the real economy in all walks of life like the Internet.

Many digital currencies that are touted by many people now, such as Bitcoin, are based on ultra-complex encryption technology, which would take hundreds of years to decrypt with current computer technology. In the future, when quantum computers come out, decrypting Bitcoin will only take a few seconds.

There are also some so-called digital currencies, which are actually carrying out illegal fund-raising, pyramid schemes and other illegal and criminal activities under the guise of blockchain.

The most important thing is that currency embodies national credit, which is supported by national sovereignty. Therefore, as a form of expression of money, digital currency cannot be separated from or fade away from this basic background.

With only a basic foundation of security experience and some management experience, it is definitely unrealistic to join the blockchain, a major trend industry, and do technology. You might as well study how to do security work specifically for the blockchain industry. By making the security pie for the blockchain industry market segment bigger and stronger, the benefits will be considerable. From this, realizing the dream of getting rich is just around the corner.

If it’s about feelings, I suggest divorce (I always advise divorce but not marriage).

If you are asking about making money, should your husband issue coins or buy coins?

If you buy coins, if nothing unexpected happens, you will still be in trouble, and the debt will make it worse.

If you are issuing coins, it is to trap other people’s money.

If you are lucky, you can make (cheating others) a lot of money.

If you are unlucky, you can directly achieve financial freedom. After all, you can’t spend much money in prison...

Thank you for the above.

.

I have been playing with digital currencies for five years, and I have also played with the capital market. At the end of 2017, I bought 20,000 to 30,000 digital currencies. Within a month, It rose to 200,000, but not much was made, and then slowly fell down in the next few months. Now I basically don’t play much. In the end, I still suffered a lot of losses. It is impossible to get rich when the market is not going well.

I think the country supports blockchain. Of course, digital currency is also a derivative of blockchain technology. In the next few years, blockchain can be said to be an outlet. It has nothing to do with digital currency. You can learn from it. Blockchain application technology, setting up a blockchain training class, studio, etc., of course, this is something you may do after accumulating a certain amount of blockchain knowledge. At the moment, you should learn first, and don’t think about it overnight. Rich, just like the Internet + online shopping a few years ago, it is a new thing, and interested friends can communicate with each other! !

If your husband can carefully read all the suggestions and answers from enthusiastic netizens, I believe he willHave a clear understanding and clear analysis of ideas.

Blockchain is nothing more than a synonym for the sharing economy, and there is nothing mysterious or mysterious about it. Investment can be done in moderation, and blockchain can be done because I am doing it. I haven’t invested a penny, but I have already made some extra money. I think blockchain is a good side job.

Personal opinions, for reference only.

It’s unrealistic. Maybe your husband doesn’t even know the true meaning of blockchain

㈡ What is blockchain and what family members it has

Simple Generally speaking, the blockchain is a decentralized system. Take the "ledger" as an example. The traditional "ledger" is controlled by the center, while the blockchain "ledger" has no center and everyone involved can "Ledger" for recording.

Blockchain generally refers to public blockchains, family members also have private blockchains, and industry blockchains.

3. Conclusion.

Blockchain technology provides a fair platform for the public. The editor believes that the application scope of blockchain technology will become wider and wider.

Finally, readers and friends who have any opinions about blockchain are welcome to leave a message.

㈢ What is blockchain

What is blockchain

What is blockchain? Many people don’t know what blockchain is. It is not very clear, and some people have even never heard of it. In fact, blockchain is a common one. I have compiled relevant information about what blockchain is for everyone.

What is blockchain 1

Speaking of blockchain, we have to mention its twin brother-Bitcoin.

Time goes back to 11 years ago. On November 1, 2008, the world was shrouded in the huge shadow of the financial crisis. That day, a mysterious geek who called himself "Satoshi Nakamoto" sent a group email.

Attached to the email is a paper titled: "Bitcoin: A Peer-to-Peer Electronic Cash System."

Satoshi Nakamoto said in the email that he is working on a new electronic cash system that is completely peer-to-peer and does not require any trusted third party. About half a month later, Satoshi Nakamoto released the source code of the Bitcoin system non-stop.

On January 3, 2009, an interesting invention turned out. Satoshi Nakamoto generated the first Bitcoin block on the server, which is the so-called "Bitcoin genesis block". Since then, the Bitcoin system has officially opened.

Having said that, you might as well stop and think about how we conduct cash transactions in real life.

Suppose you borrow 10,000 yuan from a friend and promise to pay it back in one month. You may choose to repay the loan by bank card transfer. The bank is responsible for youDeduct 10,000 yuan from your friend’s savings account and add 10,000 yuan to your friend’s savings account.

Here, the bank is the institution responsible for keeping accounts. The underlying reason why you choose bank transfer is that you believe it is more reliable and will help you transfer 10,000 yuan to a friend.

However, in the digital world, inventing a currency is another matter.

The hero behind the Bitcoin game

First of all, Satoshi Nakamoto hopes to conduct peer-to-peer direct transactions, bypassing the third party of the bank. This problem is easy to solve. Then there will be no banks. Users will issue their own currencies through a unique mechanism and trade directly with each other.

But this brings another problem. There is no bank as a reliable intermediary responsible for accounting, and users do not know each other. How to ensure that no one cheats during transactions?

For example, in the digital world, electronic files can be easily copied. 10 yuan of digital currency turns into 100 yuan by copying and pasting it with the mouse 10 times. Isn’t it a mess?

To solve this problem, we need to provide a mechanism for everyone to trust each other.

The method adopted by the Bitcoin system is to record all transaction processes openly and transparently in chronological order. These records are permanent and cannot be tampered with. This way you won't be able to do anything sneaky.

With these mechanisms, the Bitcoin system operates successfully.

This system stores data in units of data blocks, which are blocks. Approximately every 10 minutes, new blocks will be added. Each block records the detailed transaction process of Bitcoin and is timestamped. Different blocks are connected in chronological order through a certain algorithm, which is a chain.

Together, they are called "Blockchain".

In this way, the blockchain took root with the birth of Bitcoin. If Bitcoin is the star in front of the spotlight, blockchain is the hero behind the scenes responsible for providing a trust mechanism in the underlying technology.

Brand new changes in accounting methods

Although behind the scenes, the talent of blockchain was quickly discovered.

In technical terms, blockchain is a distributed ledger technology. To understand it, let’s take the simplest example.

Suppose your family keeps accounts like this: you, your father, and your mother each have an account book. You each record your own expenses, and at the end of each month, you tally the total household expenses together.

But dad likes to buy cigarettes, mom likes to stock up on cosmetics, and you like to buy snacks. You may both miss a few entries intentionally or unintentionally, and sometimes make corrections in the ledger. Therefore, when checking the accounts at the end of the month, there is always a discrepancy with the actual expenditure of the family.

In order to change this situation, you bought a new account book. You, your father and your motherPeople use a new ledger to keep accounts, remind and supervise each other, and check each expense together.

At the same time, you also agreed that once the expenses are clearly recorded, no alteration or deletion is allowed. After trying it for a few months, you found that this joint ledger matched the actual expenses of the family much more closely.

Blockchain is the second accounting method. The little story above tells us that it has at least these major features or benefits.

First of all, it is decentralized. The database that was previously maintained by one party has become jointly maintained by multiple parties. Everyone writes data together based on consensus, and no one can control the data alone.

Secondly, it allows everyone to change from keeping separate accounts to joint accounting, which brings consistency and openness and transparency to the data.

In addition, the blockchain only allows data to be written, not deletion or modification, which prevents data from being secretly tampered with.

Mutual trust between strangers

In reality, many scenarios are much more complicated than how to keep accounts at home. Moreover, many aspects of financial transactions and business processing are mostly operated by strangers. How can we make everyone trust each other?

It’s blockchain’s turn to show its talents. Don’t forget, it can provide a mechanism for everyone to trust each other from the underlying technology.

For example, when you usually go to the wet market to buy things, you may worry about whether fish, shrimp, and vegetables are safe. Some companies see business opportunities and move the data of farmers and fish ponds to the blockchain. In this way, you will know which fish pond the fish you buy comes from, and you will feel more confident when eating.

For another example, links to fundraising for seriously ill patients often appear in Moments. When making a donation, you may have some concerns: Is the patient's condition real? Can donations really be delivered to patients?

In order to eliminate these concerns, some Internet charity organizations use blockchain to allow you to clearly view the steps for using your donation. If the review finds that the patient's condition is not true, the blockchain system will automatically return the donation to your account.

In the future, what changes can blockchain bring to our lives?

It is conceivable that when blockchain is widely used in various fields of society, it will become an important infrastructure in the information age and can solve many of the headaches that currently cause us.

For example, blockchain will allow countless islands of information to be "chained" together. When seeing a doctor, there is no need to repeat the examination just because you change hospitals. Entrepreneurs do not have to go to multiple departments to go through a procedure; many transactions no longer need to be done. Third-party guarantees are required, consumers no longer have to worry about non-refundable deposits, and creators do not have to worry about their works being stolen but getting nothing...

What is blockchain 2

From an academic perspective, blockchain is New application models of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. Blockchain is essentially a decentralized database.

Many people still don’t understand this explanation, so let me make a simple metaphor.

Hypothetical situation: Suppose you have a ledger at home and you are asked to keep accounts. In the past, your parents gave you your salary and asked you to record it in your account book. If you are greedy and want to buy something delicious in the meantime, the record in the ledger may be less than ten yuan.

This is just an example. I believe that when we were children, everyone probably wanted to take some money from their parents’ pockets to spend.

Ways to use blockchain to solve problems:

If you use the whole family mobilization method to keep accounts, the above-mentioned problems will not exist, because you are keeping accounts, and your father They are also keeping accounts, and your mother is also keeping accounts. They can all see the general ledger. You can't change it, and neither can your parents. So your father who wants to buy cigarettes and you who want to eat have nothing to do.

Functional "blockchain"

It can not only record every transaction, but also can be programmed to record almost everything of value to mankind. Things: birth and death certificates, marriage licenses, title deeds, degrees, financial accounts, medical history, insurance claims, ballots, food sources, and anything else that can be represented by a code.

Each block is like a hard disk, which saves all the above information and then encrypts it through cryptography technology. The saved information cannot be tampered with.

Every 10 minutes, the blockchain system will check all data generated during the period (such as transaction records and records of when the block was edited or created, etc.) and store these data in a new area. On the block, this block will be connected with the previous block to form a chain. Each block must contain relevant information from the previous block to be effective.

Characteristics of blockchain

1. Exceptionally safe:

Unlike centralized databases owned by companies or government agencies, blockchain is not controlled by anyone. or entity's control, data is replicated (distributed) in its entirety across multiple computers.

Unlike centralized databases, there is no single entry point for attackers, and data security is more guaranteed.

2. Non-tamperability:

Once entered into the blockchain, no information can be changed, and even the administrator cannot modify this information.

Once something appears, it cannot be changed. This attribute is of great significance to the changeable and ever-changing online world that humans currently live in.

3. Accessible:

All nodes in the network can easily access information.

4. No third party:

Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so whether you are trading or exchanging funds, there is no need for a third party of approval.

Blockchain itself is a platform.

Blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Currently, each is keeping its own account.

Since there is no centralized intermediary agency, letting everything run automatically through preset programs can not only greatly reduce costs, but also improve efficiency. And since everyone has the same ledger, it can ensure that the ledger recording process is open and transparent.

Blockchain technology is the underlying technology of Bitcoin. Without the operation and management of any centralized organization, Bitcoin has been running very stably for many years without any problems, so some people have noticed its The underlying technology abstracts the Bitcoin technology and calls it blockchain technology, or distributed ledger technology.

According to a report released by Santander, Spain's largest bank, if all banks around the world use blockchain technology internally around 2020, they will save approximately US$20 billion in costs per year. Such data is enough to illustrate the tremendous changes and breakthroughs that "blockchain" has brought to the traditional financial field.

Cloud computing is usually defined as providing dynamic, easily scalable and often virtualized resources through the Internet, but it is often a centralized organization that provides a cloud computing platform. The network composed of blockchain generally does not have a specific organization, so blockchain is closer to the definition of a distributed computing system and is a type of distributed computing.

The future development and application scenarios of blockchain

1. Digital identity

Many people will encounter "prove that my mother is me" when applying for various certificates. "Mom" dilemma, with blockchain, you no longer have to worry about it.

It turns out that our birth certificates, real estate certificates, marriage certificates, etc. need a central node for everyone to recognize them. Once cross-border, contracts and certificates may become invalid because of the lack of a global central node.

The non-tamperable nature of blockchain technology has fundamentally changed this situation. Our birth certificates, real estate certificates, and marriage certificates can all be notarized on the blockchain and become things trusted by the world. , of course, it can also easily prove "my mother is my mother".

2. Health care

Simply put, it is to use the blockchain to establish a universal record repository with timestamps, so that different databases can extract data information.

For example, when you go to see a doctor, you don’t have to change hospitals for repeated examinations, and you don’t have to worry about reimbursement for medical insurance, which can save time and expenses.

3. Travel consumption

For example, we often use apps such as Ctrip and Meituan to find and place orders for hotels and other services, and each platform gets commissions from them.

The application of blockchain is to remove middlemen and create a secure, decentralized way for service providers and customers to directly connect and transact.the goal of.

4. More convenient transactions

Blockchain can make payments and transactions more efficient and convenient. The blockchain platform allows users to create smart contracts that become active when certain conditions are met, meaning that automatic payments can be released when both parties to a transaction agree that their conditions are met.

5. Strictly control product quality

If you buy an apple, with blockchain technology, you can know the entire process from the production of the fruit farmer to the circulation link. Among them are government regulatory information, professional testing data, enterprise quality inspection data, etc. A smart supply chain will make the food we eat and the products we use every day safer and give us more peace of mind.

6. Property rights protection art

The creator puts his work on the blockchain, and if someone uses his work, he can immediately Know. Corresponding royalties are also automatically paid to the creator.

Blockchain technology not only protects copyright, but also helps creators sell their works to consumers better and more directly, without the need for the assistance of distribution companies.

What is blockchain 3

Advantages of blockchain

Decentralized, it does not require the intervention of a third party and enables point-to-point transactions, coordination and collaboration. Because the data is distributed in various nodes through algorithms and has a unique verification mechanism, no one organization or individual can control the global data. Since it is distributed in various nodes, any node stopping work will not affect the entire system. Operation, this decentralized network will greatly improve data security. The data in the system is jointly maintained by various nodes with maintenance functions.

Openness. In addition to the private information of all parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain through the public interface. Data and development related applications, so the entire system information is highly transparent.

Where does blockchain come in?

Blockchain is an open, transparent, decentralized and secure technology. This technological revolution is applied to the Internet. For data-sensitive fields such as medical care, public opinion supervision, and ecological testing, it can prevent data from being tampered with and ensure the authenticity of the data.

In short, blockchain is not just a form of virtual currency, its advantages will play an important role in many industries.

㈣ Changhong-led "blockchain The implementation of the international standard "+Internet of Things Security" empowers smart home applications to accelerate

Recently, a global standards project meeting organized by IEEESA (International Electrical and Electronics Engineers Standards Association) was held online. In this meeting, the "Blockchain-Based Zero Trust Framework Standard for the Internet of Things", which was submitted by Sichuan Changhong Electronics Holding Group Co., Ltd. (hereinafter referred to as "Changhong Holdings"), was approved by the international community participating in the meeting.After thorough discussion among experts, it was unanimously approved and the project was officially launched. This 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 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 , realize the true interconnection of all things, solve key bottlenecks and core pain points, and also enhance the prosperity and compatibility of the smart home ecology." Hong Shi, founder of Yuecheng Co., Ltd.Bin 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 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 enterprises to participate in the formulation of global standards. New technologies require relevant standards to guide the development of related ecological industries. For the industrial ecology and development of new technologies In terms of globalization, its huge commercial potential requires relevant standards to guide the development of related ecological industries. Chinese companies are already at the forefront, which shows that traditional Chinese companies have increased their awareness in terms of standards, product technology, and the construction of product barriers. " 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 its transformation and upgrading. In 2018, it established an information security lighthouse laboratory to comprehensively lay out the 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 the standard, and recruiting relevant enterprises, industry associations, and institutions of higher learning that are engaged in blockchain application research, testing consulting and engineering practice in the field of Internet of Things. Schools, scientific research institutes, and service organizations are preparing to establish a blockchain-enabled IoT security standards working group to develop 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 It has won multiple industry championships, such as Internet of Things modules, rail transit power supplies, etc.," said Major General Ding, founder of Ding Technology.

“With the popularization of 5G, everything is connectedTraditional enterprises have entered the transformation track, and the construction of new business models has become an outlet for the upgrading and transformation of traditional home appliance giant manufacturing enterprises. 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 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.

㈤ What is the difference between a blockchain router and a general router?

When it comes to the new technology of blockchain, those who play Bitcoin People must know. Because it greatly improves the security of digital currency, it is widely used in the financial field. So what is a blockchain router? How is it different from ordinary routers? Let me answer it for you below.

01

More devices can be connected at the same time

Generally speaking, an ordinary TP-link router that costs about a hundred or ten yuan can only connect up to 7-8 devices at the same time. Even if it is a relatively advanced large-scale home router or office router, it currently only supports the access of a maximum of about 10-40 devices. After adopting blockchain technology, the number of devices that can be connected to the router has significantly increased, and more than 130 devices can be connected to work at the same time, which greatly improves the convenience of working.

02

The maximum wireless speed can reach more than 1000Mbps

Everyone knows that network speed is a very important thing, especially when you need to download important files, the network speed is not good, slow. During operation, it is really troublesome. If the file is up to several hundred megabytes, the computer needs to be turned on overnight for several days and nights to complete the transfer task. It is also necessary to prevent unexpected file transfer interruptions, and the blockchain router has the highest network speed. The Internet speed can reach more than 1000Mbps, which can be said to be a real roller coaster ride., upload a file, it only takes a few clicks of the mouse.

03

Multiple devices can send and receive at the same time

For general routers, there is often a delay in signal reception. Sometimes the network is clearly in good condition, but it cannot send files. Not to mention sending and receiving files at the same time, the blockchain router solves this big problem very well. It can accept and send files to multiple devices at the same time without various delays, interruptions, and inability to receive. Phenomenon.

04

Wider signal coverage

The signal reception range of general routers is often limited. Sometimes your own network will have poor signal reception due to the distance between rooms. . Even if you want to use the Internet, you have to find a network with better speed and the best signal to connect to the Internet. The signal coverage of the blockchain router is about 100 square meters, which can ensure that every family member can connect to the Internet at any location. Can receive network signals anytime and anywhere.

㈥ Is SMTH Smart Home the best in blockchain applications?

Yes, SMTH Smart Home is the first Internet of Things combined with blockchain application project.

Digital currency became popular in 2017, and blockchain became popular again in 2018. Whether it is the trend of national policies, the flow of capital or the participation of many startups, this can be well illustrated. SMTH Smart Home is one of them, and it is also the world's first impact project that combines the Internet of Things with blockchain.

SMARTHOME is an intelligent control system based on the blockchain Internet of Things product interaction center. This system is a full-carrier smart home control system. The purpose is to create a global distributed network system. Users can use the SMARTHOME intelligent control system It can build a free and meaningful smart home lifestyle in a completely secure decentralized environment.

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.

(6) Extended reading on family blockchain

The significance of blockchain:

The blockchain system itself can generate 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, theoretically achieving data self-certification in data transmission. In a far-reaching sense, this transcends the traditional and conventional information verification model that relies on a third party, 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.
