Ⅰ How to explain blockchain in a popular way

“Blockchain technology is considered to be the next generation of disruptive core technology after steam engines, electricity, and the Internet. If we talk about steam engines It has released people's productivity, electricity has solved people's basic living needs, and the Internet has completely changed the way information is transmitted. As a machine that builds trust, blockchain will likely completely change the way value is transmitted in the entire human society."

I have just come into contact with the blockchain. There are too many basic knowledge that need to be understood and known. Don’t worry, today I will popularize this knowledge for you. Today, let’s first take a look at what public chains, private chains, alliance chains, and side chains are.

II Blockchain technology is considered to be the next generation of disruptive core technology after the steam engine and electricity Internet

Blockchain technology is considered to be the next generation of disruptive technology after the steam engine and the Internet. The next generation of disruptive core technologies after the power Internet are correct. The rise of blockchain technology is considered to be a new technological revolution after steam engines, electricity, and the Internet. Blockchain can integrate physical flows, data flows, information flows, and capital flows, simplify verification, reconciliation, approval, clearing and other transaction processes, and can control the production, processing, transportation, circulation, retail and other aspects of agricultural products, industrial products and other commodities. Keep track and record. The integration of blockchain and the real economy is beneficial. The integration of blockchain and the real economy is not necessarily related to the upgrading of the consumption structure. The integration of blockchain and the real economy can reduce logistics costs, accelerate resource integration in related industries, and also bring changes to corporate management models and improve resource utilization efficiency. Wrong, the value of a commodity is determined by the socially necessary labor time to produce the commodity and has nothing to do with individual labor time.

Ⅲ What is "Blockchain"

Blockchain technology is a technology that jointly maintains reliable databases through decentralization and elimination of trust. Four keywords can be used to describe blockchain technology: trust reduction, decentralization, collective maintenance and reliable database.

When we talk about the concept of "blockchain", Bitcoin is definitely a topic that will not be ignored. In recent years, Bitcoin has begun to enter the public eye, especially in 2017, which has continued to skyrocket throughout the year, making many people aware of this emerging thing.

Blockchain is actually the underlying technology of Bitcoin. Bitcoin exists because people on the Internet who don’t know each other can move and trade digital currency through the Bitcoin network. And this is driven by blockchain technology. All Bitcoin transactions are recorded on the blockchain ledger. To a certain extent, in the application of Bitcoin, the blockchain plays the role of the underlying database of the bank transaction system. Both are for "keeping accounts". Although it is not very prudent to refer to the blockchain directly as a "database", for the sake of ease of understanding, let's temporarily call it a decentralized, shared and encrypted database. If described in professional terms, blockchainIt is a distributed ledger technology.

Blockchain can usually be divided into the following types:

1. Public blockchain. Anyone can access data on a public blockchain, and anyone can issue transactions waiting to be written to the blockchain. Participants in the consensus process (corresponding to miners in Bitcoin at the time) maintain the security of the database through cryptography and built-in economic incentives.

2. Collaborative blockchain. The nodes participating in the blockchain are pre-selected, and there are likely to be good network connections between the nodes. Other consensus algorithms other than proof-of-work can be used on such a blockchain. For example, a blockchain has been established among a hundred financial institutions, and it is stipulated that more than two-thirds of the institutions must agree to reach a consensus. The data on such a blockchain can be either public or shared internally by these node participants.

3. Private blockchain. The participating nodes are only individual users, and the access and use of data are subject to strict permission management. Most of the internally used blockchain technologies announced by some financial institutions recently are vague and may fall into this range.

The blockchain is a public ledger. There is no centralized hardware or management organization. Anyone can automatically verify the authenticity of the ledger and easily discover whether the ledger has been tampered with by others.

In a word, the blockchain is a public ledger that can be verified by everyone.

The concept of being verifiable by everyone is crucial to blockchain.

Bitcoin uses the blockchain to record all transactions, so anyone knows the number of Bitcoins on each account.

So, as a publicly verifiable ledger, what are some use cases for blockchain?

In fact, there are many use cases that can be thought of. Blockchain is suitable for any data that can be recorded on a public ledger. Here are 4 examples:

1. Decentralized domain name server, namely domain currency. The domain name server is actually a ledger that records domain names.

2. Trustless public key encryption, such as https that discards unreliable certification authorities.

3. Ownership records, truthfully record the items and their corresponding owners.

4. Contracts and performance guarantees, the account book truthfully records the parties to the contract and saves the contract text.

But don’t forget that blockchain also has a very important component.

The ledger recorded using blockchain technology will always be updated. New data such as transactions, domain name inputs, records and contracts will be converted into hash values ​​of the same length by the hash algorithm and saved. However, hashing algorithms are not only not free but also very expensive.

Therefore, the ledger itself needs to have a recognition system to recognize the person who enters the block hash value.

In Bitcoin, this system is called mining and is rooted in the Bitcoin protocol. Bitcoin miners use a hash algorithm to convert transactions waiting for verification into hash values, and charge a certain amount of Bitcoin as a service fee.

Therefore, for non-monetary use cases, blockchain needs to find a way to bear the high cost of hashing algorithms.

I would like to remind everyone that my answer mainly focuses on the possible use cases of blockchain technology, and does not cover all aspects of blockchain, such as why hashing algorithms are so expensive. I'm sure you can find a lot of detailed information about Bitcoin and other blockchain applications online.

Supplement

Although blockchain technology has many advantages, there are still some less than ideal use cases. For example, there is no way to convert Bitcoin into any national currency; a ledger with billions of data entries would take up space and be impractical.

Bitcoin has shown the world that blockchain technology is feasible in principle, and people are also trying to solve these increasingly prominent problems, such as technological transformation of Bitcoin or the introduction of a completely Different blockchain technologies. I think the following two methods are worth trying: one is to split the ledger according to certain standards such as the payer address, and the other is to introduce a main blockchain to verify the sub-blockchain. Blockchain technology is ever-changing and dazzling, and it’s unknown whether someone is already making such an attempt. But Bitcoin is still the world's first currency blockchain, what others call a cryptocurrency.

Whether in the technology circle or the financial circle, blockchain has become the hottest word, no one. Blockchain has core advantages such as decentralization and trustlessness, and can perfectly solve problems such as information asymmetry, high transaction costs, and trust of strangers in the development of the sharing economy, making "individual economy" possible. Based on this, blockchain technology is considered to be the core technology that has the greatest potential to trigger the fifth wave of disruptive revolution after steam engines, electricity, information and Internet technology.

In this context, a blockchain craze was born in society, and everyone praised it overwhelmingly. Dialectics tells us that everything has flaws, and only by seeing the pros and cons of things can we make rational decisions. Therefore, in this article, Xue Hongyan (Hong Yanweiyu), a senior researcher at Suning Financial Research Institute, focuses on pouring some cold water on the blockchain.

| What is Blockchain

Blockchain, English Blockchain, has a rather mysterious technological flavor in its name, and can be simply broken down into "data blocks" and "links". Each data block contains all the information exchange data of the system within a certain period of time, and is encrypted using cryptographic methods; the link means that each block has a link relationship with the next block, thus forming aThe blockchain.

It is generally believed that blockchain has two major characteristics: decentralization and trustlessness. A brief introduction is as follows:

Since each block contains all the information exchange data of the system within a specific period of time, Therefore, each block is equal, and the damage of a single block does not affect the security of the entire system, so the blockchain has decentralized characteristics.

Similarly, since each block contains all the information of the system, the authenticity of the information can be cross-verified. Only by breaking through more than 51% of the nodes can the information be tampered with. In a large enough blockchain system , the cost is extremely high, it can be considered that the information in the blockchain is true, so the blockchain has the characteristics of trustlessness.

Most people’s understanding of blockchain begins with Bitcoin. The relationship between the two is that blockchain is the underlying technology and concept, and Bitcoin is only the most popular application of blockchain at present. .

Maybe the above is not popular enough. Finally, let me summarize, what do you think the blockchain is? Is it a disruptive new technology? NO! According to Xue Hongyan (Hong Yanweiyu), a senior researcher at Suning Financial Research Institute, blockchain is not so much a new technology as it is a new ideological concept. The information encryption and other technologies included in the blockchain have been around for a long time, and it is more of a conceptual innovation. This is also the reason why the blockchain has a huge impact. New technologies will be surpassed sooner or later, ranging from one or two years to four to five years; only innovative ideas have enough energy to affect all aspects of the economy and society.

| Blockchain is expected to change the underlying rules of the financial system

In applications in the financial field, blockchain will change the transaction process and record keeping methods, thus significantly reducing transaction costs. It has significantly improved efficiency and is considered to have a broad market environment in digital currency, cross-border payment and clearing, bill trading, securities issuance and trading, property rights transactions, customer credit reporting, anti-fraud, and anti-money laundering.

Such a good technology is naturally sought after by everyone. Like many traditional financial people, Hong Yanweiyu resisted it at first, thinking that this thing was not that great, and did not do any research specifically. Later, as the research on financial technology gradually deepened, it was discovered that blockchain was an obstacle that could not be bypassed, because whether it was robo-advisory, big data risk control or online lending, they were only technological innovations at the financial business level and risk control level. It has not penetrated the bottom layer of the financial system. What is the underlying layer of the financial system? Naturally, it is payment and settlement, transaction rules and system interaction. What the blockchain changes is precisely the underlying rules.

Therefore, throughout the world, financial institutions are the most active in researching blockchain. If nothing else, they are really afraid. After the decentralization and trustless features of the blockchain are fully utilized, what else will the intermediaries of financial institutions do? It is estimated that this is also the first feeling of many people who have a preliminary understanding of blockchain.

In this article, Hongyanweiyu focuses on this viewSplash some cold water on it.

| Subverting the financial system, blockchain still faces two mountains

Marxist dialectics tells us that everything has two sides. The more prominent the advantages, the more obvious the flaws. It’s just the perspective. Just different. The two major problems with blockchain subverting the financial system lie precisely in the two major advantages of decentralization and trustlessness.

First, let’s talk about decentralization. First, we need to clarify a truth. Does centralization necessarily mean low efficiency? Of course not. Within a specific scope, the concentration of resources brought about by centralization can greatly improve efficiency. This is also the reason why human beings evolve from individuals to villages to tribes and then to countries in the process of evolution. Take UnionPay as an example. UnionPay is the clearing and settlement center for the domestic banking industry. After UnionPay is established, each bank only needs to connect with UnionPay to realize transactions with all banks. If it is decentralized, without UnionPay, each bank will need to When communicating with all counterparties, which one is more efficient? Therefore, there is no need to beat centralization to death with a stick. The decentralization feature of blockchain is destined to only play a role in specific fields (that is, fields that are not suitable for centralization). How can it subvert everything?

Furthermore, it is a matter of trust. There is nothing wrong with detrusting itself, but the technical logic behind it is deeply flawed. Blockchain relies on universal accounting to achieve trustlessness, that is, all transaction information is retained in each block for system cross-verification to identify authenticity. Here comes the problem. Each block retains all transaction information. There is no problem on a small blockchain. However, as more and more information is added, it will inevitably lead to an explosive growth of transaction information and will also bring information. Dramatic increase in storage costs. At the same time, the greater the amount of information, the longer cross-validation takes and the lower the efficiency. Therefore, the blockchain solves the trust problem, but it brings about rising costs and declining efficiency.

Nothing in the world is perfect, and the same is true for blockchain.

As a conclusion, Hongyanweiyu wants to clarify that blockchain, as a conceptual innovation, does have great value and can also have a disruptive impact in specific fields. However, the current one-sided thinking about blockchain is problematic. Eastern wisdom tells us that "the most brilliant and the golden mean", in the face of anything, it is wisest to maintain the golden mean.

(Text/Xue Hongyan, senior researcher at Suning Financial Research Institute; WeChat public account: Hongyan Weiyu)

As early as a few years ago, the word "mining" came with Bitcoin is well known for its popularity. Many people know about Bitcoin first and then the blockchain, and they even don’t know about the blockchain yet. By definition, blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity (anti-counterfeiting) and generation of its information. Next block.

I am not a computer technology expert. The following introduction to blockchain comes fromRead reviews from experts and friends for reference only.

If you want to use one word to explain blockchain, it is: distributed accounting.

To understand what this word means, you need to first understand that traditional accounting has a center. For example, in a bank, when you withdraw money from a bank deposit or lend money to others through the bank, the bank is the center. All these transactions are based on the bank's credit. What if the bank cheats? Or is it more serious, is the country cheating? The Kuomintang's indiscriminate issuance of gold yuan coupons at the end of its rule in mainland China, as well as the hyperinflation in Weimar Germany and Zimbabwe, which made the currency less valuable than toilet paper, are very famous examples.

Golden Yuan Coupons

This is the problem that blockchain is aimed at. They believe that decentralized accounting is non-modifiable and non-repudiable. How to achieve decentralized accounting? The basic idea is that all users store all transaction records, and through mathematical methods, it becomes very difficult to illegally modify the ledger. In this way, the reliability of the ledger is guaranteed.

Specifically, all users exhaustively enumerate random number variables, and the first user to obtain a specific required hash function value (Hash) will have the right to record this round of transactions and obtain the corresponding Bitcoins award. It is transmitted in the form of data blocks, and the data blocks are connected into a chain by appending at the end, so it is called a block chain.

After listening to the introduction, you may feel that this idea is interesting, but it is not as exciting or revolutionary as advertised. Your feeling is right. In fact, the basic logic of blockchain has some unavoidable problems.

For example, the current size of the complete Bitcoin public ledger has exceeded 150 G, and is rapidly increasing at a rate of tens of G per year - just to support 5 million users and 30 million transactions per year. If its processing volume is one day comparable to that of Alipay, the size of the Bitcoin ledger will increase by more than 500 terabytes per year. This is equivalent to backing up the Alipay server's storage data on all users' personal computers. Do you think this is a good idea?

For another example, in the traditional banking system, if you lose your password, it is no big deal. Just report it to the system in time, and your wealth will not disappear. But in the blockchain system, if you lose your password, it will be a huge trouble, and your currency will not be recovered. Not happy? Is it surprising?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system

In layman’s terms, it is to play mahjong. Four people can take turns to be the banker, and each other can shoot four people. AllThere are respective ledger records, but if you want to modify the ledger, you must have more than 50% of the modification rights, so the cost of cheating on the ledger is very high.

In the future, blockchain will be used more in finance to combat money laundering and fraud, because all information can be traced, and in culture it can be used for copyright protection, etc.

< /p>

I have seen a lot of people’s explanations of blockchain in official terms, and some may not even be clear to the person explaining it. I will explain blockchain in vernacular below to ensure that everyone can read it. Gotta understand.

What is blockchain? Let me give an analogy. In 50 years, you can buy an electric fan from the supermarket. This electric fan will automatically mine coins for you when it is blowing. You can mine coins automatically while using the electric fan. When you use this electric fan, When the fan breaks down, you can use the mined coins to repair the electric fan. Of course, you can also use the mined coins to buy a new electric fan. Many people think wrongly! Wouldn’t the profits of merchants be less? Let me tell you about a certain brand. When the products of this brand are sold to you, the products themselves may even be sold to you at a loss. However, once the number of users becomes large and the users become more sticky, they can be paid through membership fees or service fees. Such small fees or other ways to make profits. Just like this, the mined coins can be purchased and repaired. Although the merchant's profit may be reduced, the merchant has gained more users and greater user stickiness. By this time, it only takes a minute for the merchant to make money.

And the electric fan you bought is equivalent to winding it up for you. What is winding up? If you put your electric fan on the street now, and 10 people come to snatch it, you have no way to prove that the ownership of this electric fan is yours. Once you put it on the chain, it is equivalent to being tied to you. Once it’s settled, you can prove it.

Therefore, the essence of blockchain is to help make people’s lives more convenient. It is equivalent to upgrading on the basis of the Internet, making it safer and more convenient. This is blockchain! It's that simple.

The security of the blockchain is reflected in its irreversibility and the data cannot be tampered with. We all know that in today's society, any data can be modified and conquered by hackers, but the data in the blockchain cannot be changed. Once generated, it cannot be modified unless all users in the blockchain work together. Agree to modify the data, but this is unlikely to happen.

At present, the blockchain is still very immature, just like the Internet bubble burst in 2000. When the bubble bursts, a truly valuable blockchain Internet will be hatched. company.

The wheel of history will not go backwards. Many people are unwilling to accept blockchain, just like telling you that you can shop online 20 years ago.Such a ridiculous thing, time will eventually prove it.

1. The main function of blockchain is to store information. Any information that needs to be saved can be written to the blockchain and read from it, so it is a database.

2. Anyone can set up a server, join the blockchain network and become a node. In the world of blockchain, there is no central node. Every node is equal and stores the entire database. You can write/read data to any node, because all nodes will eventually be synchronized to ensure that the blockchain is consistent.

3. Everyone works on the same blockchain, everyone publicly shares the current state of the blockchain, everyone agrees on the rules for new data submission and tampering with the blockchain is prohibited. It is difficult to operate in terms of computing power.

If we assume that the database is a ledger, reading and writing the database is an accounting behavior:

Anyone can verify this public ledger, but there is no single The user can control it. Participants in the blockchain system will jointly maintain the update of the ledger: it can only be modified according to strict rules and consensus, and there is a very exquisite design behind this.

(1) Accounting, the system will find the person with the fastest and best accounting within a period of time, let this person do the accounting, and then broadcast the information on this page of the account book to everyone else on the entire network. node, which is equivalent to changing the database record; (consensus mechanism, cryptography)

(2) Verification, other valid nodes in the entire network check the correctness of the block accounting, and stamp the time Stamp to confirm that the block is legal; (timestamp, mathematics)

(3) Form a single chain, that is, compete for the next block after the previous legal block; (smart contract, encryption technology)

p>

(4) Storage, the account book is stored in blocks. As transactions increase, new data blocks will be appended to the existing chain to form a chain structure; (distributed structure, information technology) < /p>

(5) Backup, every participating trader is a node of the block network, and each node has a complete backup of the public account book, which is a distributed ledger.

Features

1. The blockchain has no administrator and is completely centerless. It is precisely because it cannot be managed that the blockchain cannot be controlled. Without an administrator, everyone can write data into it. In order to ensure the trustworthiness of the data: the technology of blockchain makes it impossible to tamper with the data once it is written.

2. Close to zero trust cost.

The cycle time required for Internet companies to build their credit is extremely long. For example, Taobao often takes several years to build its credit. In the blockchain, everyone trusts the code, algorithm and rules, so the cost of trust is extremely low.

3. Construction and intersectionThe marginal cost of easy assets approaches zero.

If traditional assets are to be used for trading, they need to rely heavily on third parties, such as investment banks, banks, securities firms, etc., for packaging and endorsement, and the fees and thresholds are extremely high. With blockchain, these will not be a problem, and the cost is extremely low.

The value transfer attribute of the blockchain also naturally solves the payment problem, and has the genes to support global payments.

Blockchain, simply put, is the underlying technology that supports ICO (virtual currency). The popular Bitcoin is an application of ICO. In other words, the connotation of blockchain is richer, and its main features are:

1. Blockchain is equivalent to digital trust. Both parties to the transaction can independently enter into digital contracts, and companies providing blockchain services are equivalent to Digital trust company;

2. The purpose and characteristics of the blockchain are "3 de-intermediaries" - de-intermediation, de-currency, and de-sovereignty; yes

3. Bitcoin is An application of blockchain, Bitcoin is a cryptocurrency, and all blockchains apply digital encryption technology;

4. The "3 Go" feature is targeted at the financial industry, and only when high frequency is required Blockchain is only needed in the financial field of transactions;

5. Large platforms with a user base are more suitable for applying blockchain, and small companies’ participation is of little value, so Zuckerberg’s 2018 New Year’s wish includes To study digital cryptocurrency. Kodak also launched a digital currency, sending its stock price soaring.

Furthermore, when it comes to Bitcoin, it can be cashed out and exchanged into the currencies of most countries. Users can use Bitcoin to purchase some virtual items, and they can also use Bitcoin to purchase real-life items. In this sense, Bitcoin is similar to the world's currency, close to gold.

Peter Thiel, co-founder of PayPal and an early investor in Facebook, believes that Bitcoin is "undervalued" by people and compares it to gold. He said: "If one day Bitcoin becomes the online equivalent of gold, then it will have room for appreciation."

But on January 3, the "People's Daily" published an article saying, "Whether it is from The increase can still be seen from the value of the currency itself. There is a bubble in the price of Bitcoin. This is an issue that needs no discussion." Data show that in the past 2017, Bitcoin has skyrocketed and plummeted: within a year, the price skyrocketed by about 20 times, and in one day It fell more than 40% within the period.

Indeed, Bitcoin has risks. However, blockchain with richer connotations obviously still has greater room for development.

Last night, screenshots of Xu Xiaoping, founder of ZhenFund, encouraging the embrace of the blockchain revolution in an internal group were posted online. In his view, the blockchain revolution has indeed arrived. “I strongly encourage everyone internally to embrace the blockchain revolution and learn blockchain technology. This is what I have concluded after long-term observation and thinking.I feel a responsibility to inform our entrepreneurs. I don’t want my views on blockchain to be misunderstood as my views on ICOs. ”

However, in the context of Internet companies and investment institutions collectively entering the market, the government will definitely take measures.

Recently, the U.S. Securities and Exchange Commission (SEC) has expressed concerns about this and shelved the proposal of two American companies to launch a Bitcoin exchange-traded fund (ETF).

In fact, this is a matter of time. Because of the blockchain The "3 go" characteristics are inherently contradictory to government centralization.

IV Blockchain can change the world like the Internet

Blockchain in layman's terms It is an "encrypted distributed synchronously updated accounting technology"
Characteristics of blockchain:
The core potential of blockchain lies in the transparency, openness, traceability, and non-tamperability of information.
The origin of blockchain:
Blockchain technology originated from a certain currency, and its essence is to create a decentralized currency system.
It is still unclear whether it can change the world in the future. It’s hard to say, but the prospects are very bright.

IV How does blockchain remove fakes and preserve authenticity

The era of barbaric growth is coming, which is both an opportunity and a challenge for blockchain.
In recent years, blockchain has gradually developed into a hot topic. Especially in 2018, which has just entered, the concept of "blockchain" has appeared frequently in the business world. So what exactly is blockchain? Why is it so popular? Entrepreneur and capitalist Liang Shiqiao pays attention?
Previously, many people believed that there was an equal relationship between blockchain and Bitcoin, but after in-depth understanding, they found that this was a wrong idea. Blockchain To put it bluntly, a chain is a distributed ledger, and Bitcoin uses blockchain technology to improve itself.
Blockchain is a decentralized technology, just like a country, in this country , the distribution of data information and rights between people is the same. There is no possibility of data fraud or loss. The two major advantages of sharing mechanism and value exchange are the power of blockchain.
Is blockchain becoming a new trend after Bitcoin?
As early as 2008, Satoshi Nakamoto published an article titled "Bitcoin: A Peer-to-Peer Electronic Cash System" on the forum. The concept of blockchain was first proposed in the article.
However, controversy has continued since the emergence of Bitcoin. Among them, the loudest opponents are Warren Buffett and Robert Shiller. Known as "Stock God" Buffett made it clear that Bitcoin "will definitely not have a good outcome in the end." Of course, there is also a lack of support. Wall Street tycoon Jamie Dimon believed that Bitcoin was a scam a year ago, but now he has overturned his previous opinion. view that blockchain is real. Regardless of the final result, in recent years, the development of Bitcoin has become more and more popular among people.focus on.
In 2013, Bitcoin skyrocketed 100 times from being worthless at the beginning. However, in the next two years, Bitcoin showed a sharp decline again. In 2014, it fell by no less than 70%. In 2015, it fell by more than 20% again. By 2016, Bitcoin entered an upward stage, and by 2017, it was resurrected. This roller coaster development not only brought losses to people, but also attracted more attention to the blockchain.
People love and hate Bitcoin. When Bitcoin becomes popular, as the core foundation and underlying architecture of Bitcoin, blockchain is gradually attracting people's attention. Blockchain is the key to supporting the formation of Bitcoin. The reason why Bitcoin can achieve such results is inseparable from the blockchain. Since every transaction in Bitcoin is recorded in a block-by-block ledger, this ledger is decentralized, and the blockchain serves as the "role" of the Bitcoin ledger. Bitcoin can be said to be the best application of blockchain, bar none.
Some time ago, Xue Manzi acquired this domain name, and in this transaction, Xue Manzi used Bitcoin to complete the transaction. This incident caused quite a stir in the circle. Recently, the frequency of use of Bitcoin in domain name transactions has been increasing, and what caused this phenomenon is the importance that capitalists attach to blockchain.
Previously, blockchain was only used by Bitcoin, but in recent years, as Bitcoin gradually spreads around the world, blockchain has begun to be applied in various projects, such as Ant Financial, JD.com, Internet and Tencent have gradually begun to apply blockchain technology. The authenticity and non-tampering nature of blockchain makes its application in other projects such as public welfare even more convenient. For example, Ant Financial has applied blockchain technology in "Hearing-impaired Children Regain a New Life", Tencent has launched the "Public Welfare Tracing Chain" and so on. By 2017, blockchain has begun to be widely used and has gradually formed a new trend.
The era of barbaric growth is coming, which is both an opportunity and a challenge for the blockchain
There is this sentence in Dickens's "A Tale of Two Cities": "It was the best of times, it was the worst of times, it was wisdom. This is an era of stupidity. People have all kinds of things in front of them, and people have nothing in front of them; people are going straight to heaven, and people are going straight to hell." Just like the blockchain, if you do it well, you will be the pioneer who participates in the changes of the times. Do it poorly and you will perish.
Today, the blockchain is facing such a situation: the rapidly developing society and the emerging enterprises have brought many possibilities to the blockchain, which has attracted more attention and accelerated the development of the blockchain industry. The enterprise application of blockchain may usher in a new era.
Blockchain can be roughly divided into three types: private chain, alliance chain and public chain. Each blockchain corresponds to different scenario applications. The most critical difference between these blockchains is the degree of decentralization. Limit scope. Blockchain is also widely used due to its distributed recording of data, data cannot be tampered with, and is open and transparent. Different from the transmission of information on the Internet, blockchain is the transmission of value., can be said to be an upgrade of the Internet. Based on this, blockchain is considered to be another central technology that is very likely to cause a disruptive revolution after steam engines, electricity, and the Internet.
But the blockchain is not omnipotent:
Firstly, there is delay in the blockchain. Take transactions in Bitcoin as an example. Its effectiveness is affected by network propagation and takes ten minutes to complete. Be informed and recognized;
Secondly, the blockchain itself does not have the two functions of "modify" and "delete", which makes post-processing very troublesome if errors occur when recording data.
In addition to its own limitations, in the face of the complex enterprise market, blockchain, which has gradually become the new darling of the market, has also led to a series of "accidents" such as "coin speculation" and "pseudo-blockchain". .
In September last year, the country had banned the trading of virtual currencies such as Bitcoin and ICO, but the strong money-making effect has brought the currency speculation boom back to people's attention. First, Xunlei launched Wankecoin (now called LinkToken) in October, then Renren released the blockchain project "Renrenfang" and the token RRcoin, and Kodak launched Kodak Coin. Many companies have entered the blockchain development industry. currency, which makes the phenomenon of "coin speculation" sweep across again.
Currently, there is no shortage of money-making projects on the market. Companies are mixed in the blockchain application market. It is difficult for investors to distinguish the pros and cons of projects, and there are even situations where bad coins drive out good coins. In the market, "processing" of public data has become a social norm. For example, in order to attract more consumers and capitalists, companies will modify the data they publish accordingly to attract users to choose and Corporate investment.
In addition, some companies are trying to make money in the name of blockchain. After seeing the benefits brought by blockchain, some companies rushed to enter the market before they understood the operation of blockchain in order to be the first to enter this trend and obtain high profits; some even used blockchain gimmicks to do so. Make money wantonly and retreat quickly after obtaining high profits. This blind application of blockchain has caused some companies that really want to apply and develop blockchain to gradually withdraw from the market, while some companies that mainly focus on making money are still active in the market, which has greatly affected the development of blockchain. normal development trajectory.
Although the blockchain has the core technology to create new trends, because it is still in its infancy and is not mature enough in all aspects, it will still bring about various problems such as "coin speculation", which have become obstacles to the blockchain stumbling blocks to chain development.
Will the increase in entrants accelerate the bursting of the blockchain bubble?
Relevant data shows that from November 2015 to December 2017, the growth rate of blockchain-related occupations reached 631%. However, in this huge data, there are some companies that join the blockchain ranks with the mentality of "getting a quick buck and leaving", which disrupts the normal development of blockchain in the market and further promotes the bursting of the blockchain bubble. 's appearance.
Different from previous years, blockchain has developed very well in recent years, and its application scope has expanded to various fields such as finance, education, government, cloud computing, medical care, and insurance.area. As the number of entrants gradually increased, many irrationalities appeared in blockchain applications, causing batches of contestants to withdraw.
Recently, a WeChat group called "Blockchain without Sleep at Three O'Clock" has aroused heated discussion. In this group, some well-known people from the industry gathered to talk about blockchain and Bitcoin day and night. Have an in-depth discussion. Among this group of people, blockchain has basically become their “belief”. It seems that if you don’t understand blockchain, you will be eliminated by the times. This kind of blindly following the trend reflects not only people's anxiety about the development of the times, but also the market's strong demand for blockchain. Furthermore, the recent popularity of blockchain concept stocks has triggered more and more investors to enter the blockchain market, causing the blockchain market to expand rapidly and create bubbles.
Furthermore, since the blockchain is still in its infancy, there are still many aspects that need to be improved. At this time, it is tentative for companies and investors to enter the blockchain. Blockchain, a technology with revolutionary significance for the times, still needs to be gradually developed. Moving forward rashly will only push the blockchain that is originally on the right track further.
Regarding the understanding of the development of blockchain, Gartner consulting firm has previously analyzed relevant aspects: a new technology basically goes through five stages, namely the embryonic stage, the popular expansion stage, the bubble bursting stage, and the upward recovery. period, maturity period. According to Gartner's analysis in 2016, blockchain is already in a period of inflated expectations. At this time, it is in a period when the bubble is about to burst, and it will take 5 to 10 years before blockchain reaches maturity. .
Will blockchain become the key to the era of change?
2017 can be said to be the year of the explosion of blockchain, with various capitals getting involved in blockchain. Although it has brought many problems to the market, the role of blockchain in market development cannot be ignored. Recently, "Three Questions about Blockchain (Economic Hotspots)", "Seizing the Opportunity of Blockchain" and "Being a Leader in the Digital Economy" published in the "People's Daily" have clearly stated the impact of blockchain on various fields of the market. important role.
Issues such as delay, "pseudo-blockchain", and "coin speculation" will further attract people's attention after the blockchain bubble bursts, and more standardized market development will occur. Today, blockchain is still in its infancy. As more and more entrants enter the industry, a blockchain bubble is inevitable in the future. But after the bubble, blockchain will bring a disruptive experience to the market and usher in a new era.
Blockchain itself emphasizes "decentralization". In order to meet the ever-changing real needs, blockchain is upgrading to "multi-centering", which will completely break the data "island" and achieve comprehensive interconnection of information. situation. It can strengthen the trust security system, improve transaction efficiency, and meet the application needs of the increasingly developing era.
In short, the explosion of blockchain is inevitable. Its decentralized nature avoids the monopoly of Internet giants and brings development opportunities to many entrepreneurs and investors. But at the same time, based on blockchain, it can reduceIt has low transportation costs, is open and transparent, cannot be tampered with, has strong permeability, and is more convenient for market management. In the future business world, there will be a blockchain era that "removes the false and preserves the true".

Ⅶ Digital transformation of the power industry: a change that is easier said than done (with six selected plans)

Currently, the power industry The industry is keeping up with the trend of the times, actively responding to the construction of the digital economy and Digital China, and carrying out digital transformation. However, with the production, transmission and consumption of electricity, a large amount of information and data are generated in each link of power generation, transmission, transformation, distribution and consumption. How do power companies use this data? How to ensure data security? How to break through internal and external resource circulation obstacles and operating bottlenecks?

Electric power is in urgent need of digital transformation

Under the wave of digitalization, many domestic and foreign companies are activelyCarry out digital transformation practices, fully introduce digital thinking and technology, and optimize all aspects of enterprise manufacturing, marketing, and operation management. "Under the new round of power reform, electric power companies are facing increasingly severe market competition and internal pressure to reduce costs and increase efficiency, and they are also in urgent need of reform." Jiang Jin, a third-level expert at the China Southern Power Grid Digital Grid Research Institute, was accepting "Communications Industry News" said in an interview with all-media reporters.

When talking about the current status of digital transformation in the power industry, Mao Xuchu, deputy general manager of Luculent Intelligence and director of Su Chang Industrial Internet Research Institute, told all media reporters of the "Communications Industry News" that at this stage, the power industry The industry has a high degree of automation, a good informatization foundation, and complete systems. In terms of digital transformation, power companies pay more attention to the mining and application of data value, as well as the application of new technologies such as the Internet of Things, big data, and artificial intelligence.

Recently, Pan Hailu, deputy general manager and product director of Keyuan Smart Power Plant Research Center, said in an interview with an all-media reporter from the "Communications Industry News" that in the process of informatization construction and digital transformation, intelligent sensing There are still some deficiencies, such as massive data being idle and unable to exert value, a large number of systems forming information islands that cannot be effectively integrated, and issues such as equipment and information security that need to be further explored and resolved.

Humi.com CEO Gong Shukai said that companies in the power industry usually face many challenges when carrying out digital transformation. However, advanced infrastructure and massive data have laid the material foundation for the digital transformation of power companies. At the same time, with the rapid development of high and new technologies such as big data, cloud computing, Internet of Things, mobile Internet, intelligence, blockchain, edge computing, 5G communications, etc., the process of digital transformation of electric power has been accelerated.

He Dongdong, co-founder and CEO of Shugen Internet, believes that the general trend of comprehensively promoting digital transformation in the power industry is to use digital technology as the starting point to promote the digitization of operations and assets, and then realize the transformation of the entire industry from production management to the comprehensive digital transformation and upgrading of the business model, and ultimately to a new model of energy and services, driving changes in the entire industry chain.

Opportunities and challenges coexist

In recent years, with the continuous development of the Internet of Things, big data, cloud computing, artificial intelligence, etc., the digital transformation of the power industry has developed to a new stage. With the continuous improvement of distributed energy, energy storage, and grid technologies, the digital transformation of the power industry is full of opportunities and challenges.

Gong Shukai pointed out that the first issue is the management of power generation equipment. Since power generation requires continuous production, equipment failure will cause huge losses. Whether it is hydropower, thermal power, wind power, or photovoltaic power, the level of equipment maintenance needs to be improved. The second is the problem of grid-connected dispatch. Currently, various power sources need to be coordinated and dispatched, which poses challenges to power generation prediction. New energy power stations have limited voltage adjustment capabilities, which can easily lead to sub-synchronous power generation.Step ramp waves, etc., have adverse effects on the safe and stable operation of the system. The uncertainty of the power station output makes the power grid complex and changeable, increasing the difficulty of power grid operation control. Safety issues and power prediction problems lead to difficulties in grid connection and absorption, and power curtailment. The rate remains high.

Pan Hailu believes that safety is the first priority. With the continuous development of Internet technology, how to ensure power plant production and data security has become a top priority, and autonomy and controllability have begun to become a basic requirement. Secondly, data generates value. During many years of informatization construction, a large amount of production and operation data has been generated, but in most cases these data do not exert much value. Finally, a unified management platform. In the process of digital transformation of electric power enterprises, due to historical reasons, there may be products from various manufacturers and platforms, resulting in the formation of information islands, inability to work together, and even difficulty in maintenance and upgrades.

Mao Xuchu said, First, for the entire power generation industry, there is a demand for changing from process-driven informatization to data-driven informatization. In the process of digital transformation, higher requirements are put forward for enterprises. , which requires not only strong technical platform support, but also practical methodology, data application theory, and advanced management awareness. Second, in the process of smart platform transformation, not only IT personnel but also OT personnel are required to be deeply integrated. However, due to the gap in their own professional fields, the integration is not ideal.

Currently, the digital transformation of all walks of life is in full swing, and the power industry has higher requirements for intelligence. Although the digital development of the power industry is ongoing at this stage, it is still necessary to seize this opportunity to achieve digitalization as soon as possible. transformation.

Digital transformation: starting from the pain points

“One of the biggest peculiarities of the power industry is that electric energy cannot be stored, and production, supply and sales are dynamically balanced and completed at the same time. From power generation, transmission, and consumption Looking at each individual link, a large amount of data will be generated, and the industrial Internet operating system can analyze the data and optimize the link." He Dongdong said frankly.

Currently, the industrial Internet platform has become an important way for the power industry to solve the problems of remote maintenance of equipment and grid connection and consumption of new energy. At present, power equipment manufacturers, big data service providers and power generation companies are cooperating through the platform. Access real-time data from the source, network, and load, and use big data analysis and modeling to carry out systematic scheduling and management and control services. On the one hand, it supports new energy to achieve unattended, less-attended, and regionalized maintenance models, and on the other hand, it improves the grid connection rate and overall power consumption efficiency of new energy.

So, how to open up the data of the whole chain, so that energy can achieve true dynamic optimization from the production side to the demand side, so that the data can maximize its value? He Dongdong believes that, first of all, it requires long-term precipitation and analysis of data to continuously enhance the industry capabilities of the industrial Internet operating system; secondly, it requires the upstream and downstream of the industrial chainIt is necessary to open up and eliminate information islands as soon as possible; finally, it is even more necessary for the entire industry to establish a digital transformation mindset and make joint breakthroughs in technology.

Pan Hailu suggested that the power industry needs to pay attention to the potential value of data, build a unified platform, and empower business development on the premise of safety. Let security and intelligence be implemented from devices, platforms to business systems. First, coordinate with the national industrial upgrading strategy to develop a new generation of intelligent controllers to achieve complete autonomy and control, and create a truly intelligent autonomous control system. Second, at the digital level, use technologies such as big data, artificial intelligence, and microservices to implement application apps such as three-dimensional digital power plants, digital twins, process simulations, and intelligent early warnings to help enterprises reduce costs and increase efficiency, improve operational efficiency, and complete Digital transformation.

Mao Xuchu believes that, first of all, the digital transformation of enterprises requires top-level planning through professional consulting companies, including technical architecture planning, business architecture planning, and organizational structure planning. Secondly, enterprises must make full use of data thinking to build data-driven platforms and realize in-depth mining and utilization of data value. Finally, when enterprises are engaged in digitalization and intelligent construction, they need to find manufacturers with independent industrial Internet platforms and industry best practices that have a better understanding of the business scenarios of the power industry to cooperate. At the same time, the process of digital transformation does not happen overnight and requires cooperation with manufacturers. Comprehensive and in-depth cooperation will promote the integration of IT and OT to ensure the success rate of construction implementation.

Jiang Jin said that in the process of serving power companies, the comprehensive digitalization and intelligence of the business will inevitably face higher requirements in terms of safety and security. The China Southern Power Grid Digital Research Institute strictly implements the "three synchronizations" principle of the state and China Southern Power Grid in informatization construction and network security, and carries out special upgrades of the "Digital South Grid" key information infrastructure, security assessments, domestic encryption application transformation, and power monitoring system security Compliance transformation to further improve structural safety, ontology safety and infrastructure safety.

Green energy saving, win-win dual carbon

According to public data, the carbon emissions of the power industry accounted for more than 40% of the entire energy industry in 2020. It can be seen that in helping the power industry achieve the "double carbon" goal, industrial Internet companies can help the power industry accelerate the construction of new power systems, improve power grid data collection, analysis and application capabilities, reduce energy losses, and exert their influence on the energy resources of the whole society. It plays a positive role in optimizing allocation, promotes green energy production and consumption, implements energy development strategies, and supports the realization of the "double carbon" goal.

Gong Shukai believes that in the future, under the "14th Five-Year Plan", my country's power industry will gradually enter a stage of high-quality development. First of all, the central role of electricity in energy continues to increase, making ensuring electricity security a core element of the new energy security strategy. It is an urgent need for the power industry to implement the overall national security concept; secondly, the supply-side structural reform continues to deepen, leading the green and low-cost Carbon cycle development is the key to the construction and development of the power industry.It is an inevitable requirement for ecological civilization; thirdly, seizing the historical opportunity of the new round of scientific and technological revolution and deeply integrating innovation and cutting-edge technology is an important task for the power industry to implement the major strategy of strengthening the country through science and technology; finally, exploring new models of global energy governance and strengthening international Cooperation is an important measure for the power industry to implement the “Belt and Road” initiative and build a community with a shared future for mankind.

He Dongdong suggested that in the reform process of the power industry, the first priority is the reform of the energy structure; secondly, the industrial Internet should comprehensively and deeply empower the digital transformation of thermal power generation; finally, in the power transmission link , through 5G + Industrial Internet, Vision + Industrial Internet, and AI computing, it can also comprehensively improve the monitoring and pre-maintenance capabilities of power transmission and distribution links, greatly reduce failure rates and maintenance costs, improve operating efficiency, and thus promote energy conservation and emission reduction.

Wang Chong, a technical expert at the Digital Grid Research Institute of China Southern Power Grid, told reporters from the Communications Industry News that under the dual-carbon goals, new energy will become the main power source in the new power system, with high penetration rates. New energy will profoundly change the form, characteristics and mechanism of the traditional power system. In the new power system, the system volatility increases sharply and the inertia is significantly reduced; the distributed characteristics of the system are more obvious and the number of equipment increases sharply; the interest pattern of the diversified market more complicated.

"In the future, the power industry will show the following trends on the road to digital and high-quality development. In terms of technology, the platform trend will break the current situation of independent and scattered data information of various systems and departments and data islands. ; At the business level, integration from infrastructure to production, finance and business integration, business and performance integration, group and power plant integration, MIS and SIS integration; in terms of overall ecology, ecological trend, the industry chain will be based on a large platform Use data to improve management and improve the efficiency of supply chain and resource coordination." Mao Xuchu said frankly.

Digital transformation of the power industry: a change that is easier said than done (with six edited plans)

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

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

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

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

First, the era of electrification of transportation.

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

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

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

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

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

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

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

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

Second, mobile energy Internet.

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

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

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

The third blockchain technology promotes the mobile energy Internet.

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

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

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

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

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

IX hundredJia Zhengming | Cai Dong: The "Truman Show" hidden under blockchain technology

Discussions about the application of blockchain have become frequent nowadays appear in public view. However, when the technology itself is mature enough, what will happen if one day blockchain is truly used in all aspects of life? Imagine that one day, human beings’ entire lives from birth will be recorded on the chain. Will life on the chain be a beautiful credit society like the "Peachland World", or will it be like the movie "The Truman Show" that records life without distinction between right and wrong, making people want to escape?

In this issue of People's Digital FINTECH Hundreds of Controversies column, Mr. Cai Dong, Chief Information Officer of McDonald's (China) Co., Ltd., was invited to talk about whether we will inevitably become a movie from the maturity and application level of blockchain technology. Like Truman in the movie, he lives in the anxiety of being "surveilled" by the whole world all the time.

The 1998 movie "The Truman Show" tells the story of an ordinary little man who, without knowing it, The story of a man who was made into a famous TV star, but was completely deprived of his freedom, privacy and even dignity while the whole world watched him every moment, and became a victim of the mass entertainment industry. In the era of digital economy, Truman’s world is hidden in the technical characteristics of blockchain: decentralization (many viewers), openness and transparency (truth is revealed), and non-tampering (cannot be hidden), which sometimes reveals disturbing features. appearance. In the process of application, will such technology have a huge and irreversible impact on social concepts and personal life? Are we inevitably going to be Truman?

Blockchain technology is considered to be the next generation of disruptive core technology after steam engines, electricity, and the Internet. Since blockchain technology has the characteristics of decentralization, openness and transparency, and full traceability, it can be used to build an encrypted database that is shared by multiple parties, active in multiple places, cannot be tampered with, and has strict timing. Many people in the industry are optimistic about its development and believe that it will It is an upgrade and supplement to existing Internet technology and is expected to become the cornerstone of the digital economy era. However, from the perspective of practical progress, the difficulty of blockchain technology in the implementation process and its impact on current concepts, regulations and social systems have gradually revealed the hidden problems behind it.

I have returned to China since the end of 2015 and have carried out a very grand practice of digital transformation of physical business in Wanda Group, and I have a lot of emotions. First of all, we believe that blockchain technology itself is not yet mature, so we have participated in various standardization organizations and important international open source projects, and have conducted a lot of basic ecological cultivation and open source research and development work. For example, in 2016 and 2018, under the leadership of the Ministry of Industry and Information Technology, we compiled the Blockchain White Paper on the Development of the Blockchain Technology Industry with other leading companies, which can provide a relatively complete guide for companies on how to adapt to local conditions.Use blockchain technology to help government agencies evaluate and formulate preferential policies for blockchain empowerment.

From a technical level, although blockchain has the technical ability to record data and cannot be tampered with, copied or deleted, when applied to real life scenarios, A key problem must be solved: How to turn "atoms" in real-life scenarios into "bits" and then put them on the chain? If the authenticity of the data itself is doubtful, or even maliciously falsified by data observers, not only is it meaningless to put it on the blockchain, but its non-deletable nature will also produce meaningless occupation and even negative effects. For now, there is no universal standard for mapping the physical world and the digital world. Although physical businesses have long begun to use IoT technology to digitize the physical world and have achieved many benefits of digital transformation, there is also a lot of IoT data. example on the chain, but this is not enough. Blockchain technology, whether it is the data itself or the hash value, is the core technical bottleneck of data completeness and system mass processing performance, which has led to no large-scale application so far.

From a social perspective, the decentralization, self-management, and collective maintenance characteristics of blockchain technology are bound to subvert people’s production and lifestyle and dilute the concepts of state and supervision. , impacting current legal arrangements. For these, the entire world completely lacks theoretical preparation and institutional discussion. Even for Bitcoin, the most mature blockchain application, different countries have different attitudes, which inevitably hinders the application and development of blockchain technology. For another example, the openness and transparency brought by blockchain technology can prevent some middlemen from making profit in the entertainment market and bring benefits to consumers of cultural products. It can also make copyright information open and transparent and stimulate active creation in the entire entertainment industry. , produce high-quality content, but it is difficult for users to change their habit of listening to music on centralized platforms in a short period of time. Vested interests in these fields will also be "taken away from the cake". For example, the traditional ticketing market will be challenged. , and may also lead to strong backlash from large companies.

In addition, the threats to personal privacy data that may be brought about by blockchain technology during its application are also worrying. As the digital economy develops in full swing and data is increasingly recognized as a factor of economic production, user data ownership has been repeatedly violated and privacy leaked. Giant Internet companies have gradually become data oligarchs, leading to global conflicts over data ownership and privacy protection. Intensifying. The reasonable use of user access, consumption and other behavioral data and user privacy data is an important challenge for modern civilization. It is not only a technical challenge, but also an ethical and compliance challenge. For example, if blockchain technology is applied to the field of biological big data and users' genetic sequencing data are uploaded to the chain, how can the sequencing data of many users be reasonably and legally used in the field of scientific research to reveal the mechanisms of diseases? Benefit future generations of mankind, andHow to prevent users’ genetic disease and cancer risk information from being leaked by others, which would have a fatal impact on the user’s personal emotional life and social evaluation? The implementation of blockchain technology in the future will inevitably involve choices about the fields it enters, as well as weighing moral and ethical issues.

We can foresee that in the future, more and more things and behaviors will be digitized through data on-chain, and then Be capitalized, but the original ownership of the data is always with the data owner, who is the owner of the data. While enjoying the online value-added circulation of the digital economy, it will also bring people more diverse economic activities in the real economy. But think about this kind of life, do you want to escape?
