How To Use The Blockchain To Protect The Trillion-Dollar Intelligent Import And Export Logistics BusinessOn November 22nd, the 2018 Global Smart Container Industry Alliance Annual Meeting and Smart Container Standards Publicity Training Conference was held in Shenzhen. Waltonchain CTO Wei Songjie delivered a speech at the scene. Professor Wei expounded the origin and development of blockchain and proposed the solution of blockchain technology applied in intelligent import and export logistics for the first time. He said that compared with the traditional way of shipping, the application blockchain can improve the time efficiency of more than 50% in the intelligent logistics industry and reduce the management cost by more than 30%.
The following is the full text of the speech:
Good afternoon everyone, I am Wei Songjie. Today, the theme I gave to everyone is "blockchain: data container, pass-through transport line, trust notary". Because today's conference theme is a smart container, I also borrowed a topic called a "data container." In fact, in our information security industry, we call this a data package or a package called data. They are actually quite similar in nature, and data is also goods. For us, data is something of value.
In today's speech, I mainly talk about three parts: blockchain + digital certificate capability, blockchain + port cargo application scenarios, blockchain + intelligent import and export logistics solutions. Some of these contents are exchanged with some experts in the logistics industry. Some of the things may not be too mature and accurate. I am as a layman in this swearing, and I would like to ask you.
The blockchain has been a hot word in recent years. In my opinion, the biggest use of the blockchain is not "speculation", "sell one", "sip", these are their superficial articles. The biggest feature of this technology is its digital passability.
Dr. Zhou’s speech just said that what is the core in the container-based goods circulation industry? He said that documents are the core. For the circulation of goods, we need a list to prove. In the field of our blockchain, we call this core a pass.
Let me talk to you quickly, what is the blockchain?
In fact, this year happens to be the tenth anniversary of the blockchain. As for its origin, at the earliest, it came out as the underlying technology of Bitcoin, and its data structure is a chain structure. So what is it used for? It is used to book bitcoin. For example, who transferred to whom, how to turn, and so on. It is a distributed ledger, a public ledger, distributed meaning that there is no central bank, not a single individual has the final say. It has a wide range of applications, but most of the current applications still revolve around its financial transaction attributes.
In our field of computer science, we have used the term blockchain for less than a decade, but we have used this technology for decades. What do we use it for? In fact, we used to call it a distributed database a long time ago. That is to say, the database that everyone uses now has (several) servers. That distributed data means that instead of having a centralized server to store data, it means that the data is distributed in many different places, so we call it a distributed database.
Of course you have a database, you always have software, but also have a system. So in fact we have studied more accurate nouns. For example, let me study the distributed system for more than ten years. At the same time, we also use the blockchain-related things to achieve the measurement and circulation of this value. This has actually been used since, for example, QQ has Q coins, many games have points or coins, so this is not new. Of course, we study from the perspective of how the entire process, including the value of commodity services, is measured and quantified.
In the end, what is the main feature of the blockchain and what is it used for? Be an endorsement of trust. Therefore, we often hear people say that I can't change the data on the blockchain. You can't lie to me. It can't be fake forged, can't be lost, and so on. In fact, its core is, if you believe it or not, you believe it, if you don’t believe it.
In fact, long ago we were able to do trust-based or data-based trust and verification. But what did we call it at that time? We call cryptography. So I often talk to my students during the exchange, the blockchain thing, now it can not be said to be a gimmick. Again, we rely on it to do research, write papers, and then do projects. In fact, it is more like an application innovation—that is, combining existing technologies in a new way and using them in newer ways. Broad application scenarios.
Which combination of technologies? The core of distributed systems, peer-to-peer networks, and cryptography is these. Therefore, those people say that the blockchain is very important, or very useful, and its elements are summed up in fact. Then what effect does it use to achieve these effects? I think it is the effect of interconnection, interoperability, mutual trust, mutual benefit and mutual integration.
The Internet is easy to understand. In fact, our current information systems, including our devices, are rarely fragmented or run independently. Most of them are networked, including your mobile phone and computer. If you can't access the Internet, the mobile phone is not yet available. It’s a brick, right. No use. Now everyone can't do without the network. In fact, the blockchain is the same. Its underlying core is that it can be networked and does not depend on a specific or specific network. It does not depend on a specific server and does not depend on a specific SP (network service provider). I was able to connect to the Internet. This time we called P2P (peer-to-peer network), this is no stranger. Because a long time ago, I remember that I went to the movies and songs. The eDonkey used in that year was P2P. What it wants to achieve is interconnection, which means that you are not an individual, you are not separated, P2P technology is how to connect with others.
The second is interoperability. The reason for interoperability is because everyone wants to communicate. For example, everyone here is Chinese. If I speak a foreign language here, everyone knows English, and Japanese may understand it. But for example, Burmese and Vietnamese, you may not understand. At this time, what I said is still human, you are all human, but everyone does not understand, why is this? Because it does not have a valid specification. There is no rule that this field can only speak Chinese, or that this field can only say what you and I can understand, and this is the reason for interoperability. The blockchain, which defines a set of interworking rules or norms. Just like the (national container) standard we set here today, why should this standard be? Because if the standards are different, for example, the container you are ten meters high, my two or three meters high, then you said how to pull this truck? How can I store this warehouse? How do I load the goods? Right. This is the standard use.
The third is mutual trust. I just said, what is data? What is useful is the data. What kind of data is useful? Real is useful. Then how is it true? You have to be able to verify, or you have to be able to prove it. Therefore, the blockchain uses cryptography to achieve mutual trust. Think about it, the information system we use now, or the computer and related equipment, what is the most valuable, that is, data. In fact, if I lose a mobile phone now, I don't feel bad at all. Thousands of dollars can buy one back. But what is the pain? It's the address book, chat history, and photos inside, maybe there are sensitive photos. This kind of data is the most valuable.
The fourth is reciprocity. Blockchain It is the circulation or value sharing that can achieve this value. Of course, there is a lot of value in this system. In fact, it is a number. Just like we have mobile payments now, we rarely use money. Credit cards are not very useful, so money is a symbol for us, and the symbol is a number. It's the same, but this number is valuable, or the back of the number is money, and the blockchain can achieve this effect. Of course, if there are benefits, some people will suffer and some will take advantage of it. This is reciprocity. Our best effect is to achieve the Pareto improvement in economics. If I take advantage of it, you will not suffer. This is a win-win situation or a win-win situation. The blockchain can do this.
The fifth is called mutual integration. In other words, since everyone is living together in an ecological environment to live together, coexist, agree, and work together, then everyone must have a way to achieve consensus. For example, today, who should we listen to? Of course, we should listen to the organizer and listen to the host, because I recognize you as the host, right. But if there is a spoiler, he will not recognize it. He has not reached this consensus, and this matter is troublesome. So, inside the blockchain it has a series of algorithms and methods to achieve consensus. For us, the simplest consensus or the easiest to understand is that everyone votes. Who do you think is the moderator, who has the most votes, and who is the moderator, but the simplest (fairness) is often the hardest to achieve. But in fact, these (consensus) are the core elements of the blockchain, and what effect can be achieved with these elements, and what is the use of these effects, this is its definition. Now our country is working on the relevant standards for the blockchain, but before this appearance, whether it is the corporate or academic world, or our Internet enthusiasts or blockchain enthusiasts, they do not have a standard definition. Some people call it a distributed system, someone calls it a chain, and someone calls it a mesh structure. I have a little bit inserted here, although it is called a blockchain, but in fact, in terms of chain structure, the chain is one-dimensional, but it is a form, and the chain really has two-dimensional or even multi-dimensional structure, two Dimension is a mesh structure, multidimensional. We call it a complex mesh system. So the definition of it is really just a statement or two words.
Since I am not coming to invest, this is not a preaching. You can't just say its benefits, let's be honest, let's talk about some interesting things in this technology.
The first one is that many people say that the blockchain is very good and decentralized, but is it decentralized? This is really debatable. Absolute centralization or absolute centralization is definitely not good. After all, I am not the "center", right. If anyone is the "center", who will definitely say it. Therefore, everyone must be hoping to be able to be equal, to be able to disperse, to be able to participate in and to make decisions without their own centralization. But the blockchain, it is not really decentralized, he is not without a center, he just turned a center into a lot.
Who has the final say? Everyone has the final say. How do you say it? A lot of ways. For example, the easiest way to vote, one person, one vote, is now very popular is the calculation power, who counts fast, who has the final say. There is another way, that is, whose shares are large. One person, one vote is the same situation for everyone's shares. Based on POS (consensus mechanism), it is actually to look at the rights and interests, to see who owns the shares, and the big one he said is more than me. In addition to this, there are many other ways. So we say that the blockchain is actually multi-centered, and there is a problem with true decentralization. For example, one problem we often face now is its efficiency problem. Well, take Bitcoin as an example. Everyone often says that I can get money by buying coins. But you have to know that you are actually launching a transaction on the Bitcoin network or system, or I will transfer you a sum of money, you have to wait a long time to receive it - this is not a few minutes, a few seconds, but maybe a few Ten minutes, a few hours, or even a few days. Therefore, decentralization will have efficiency problems.
Many of the so-called public chain or blockchain systems we have seen now have this efficiency problem. In other words, he may have a process, the algorithm is correct, the technical line is right, there will be too many people, especially in China, because the most important thing in China is the user, the most important thing is the user. Scale, efficiency will have problems. So our current research direction, including our application scenarios, is mostly multi-centered. Therefore, we call this multi-centered, not a center, that is not good, it is the original system, not the real center.
The second one is called the virtual and real of trust. In fact, the data is placed on the blockchain, can you really believe it? Put the blockchain, is it true? Of course it is not the case. I put a bunch of garbage into the safe, it is still rubbish, it is not worth it. Therefore, it depends on the entire ecology of the data or the entire life cycle, especially the stage of data perception or acquisition.
We now use the blockchain, including our company, some of our projects. In fact, we use a combination of software and hardware to solve how to ensure that the data you get is first-hand data, no noise, no errors, no interference. There is no such forgery, and then put it on the blockchain immediately, so that I can guarantee that the next life cycle of this data is real and verifiable. So this is why many people think blockchain data is true. However, if you put it true, it is true. If you are on vacation, it is fake. It guarantees that this data has not been altered and can be verified, but does not guarantee its original authenticity.
The third is the truth and falsehood of our consensus. The fact is that the consensus reached by the blockchain algorithm is the correct consensus? The correct consensus is that the American president is Trump. Is he really getting a 50% (vote) +1 vote? No, everyone knows that Hillary’s votes are higher and they get the same amount of votes. It was only because of the rules of their electoral college that Trump was elected. What does this show? Explain that our consensus mechanism can actually determine whether our final consensus is a general consensus, a relative consensus, or a professional consensus, and it depends on the scenario. So, you should first think about using the blockchain, and then design a consensus mechanism. After all, there is no universal technology that is universally applicable.
The last one is called the right and wrong of the data. What does it mean? Here is to say that the data is placed on the blockchain, we can say that it can not be tampered, can not be forged, can not be changed, it will not be lost, but can this really achieve this effect? In this (blockchain) industry, we often hear news that a word is called a fork. In fact, this is to say that the original chain grows in a single item, and it grows more and more in a while. When it grows long, it splits. Why is it forked? Because there is no consensus. Because some people think that it should grow like this, some people think that they should grow into that, and then there are people on both sides to support, so they fork. So this shows that the right and wrong of the data depends on who? Depending on the user, it depends on the consensus results of the user. So these are relative, in fact nothing is absolute. Including our cryptography, are you absolutely safe, definitely not. As long as I can live long enough, then I will try hard, and one day I will be able to try it out, right. The only absolute thing in us (information technology) is that it is the quantum code, which is absolutely safe. But this is a bit of a problem.
So now, in less than a decade, the blockchain has evolved in three different phases.
We have phases 1.0, 2.0, and 3.0, but it doesn't make sense to say that the specific technology is too boring. What we have to say is that 1.0 solves the problem that is too simple, that is, to record the account or to use it as a book; 2.0 can only fulfill the contract, can we say what we say, we write the program people like to write Some conditions are judged and looped. Actually, these conditions can be written in 2.0. What is the use of this condition? We will see it later. The direction that is currently developing is 3.0, 3.0 is to do things, that is to say, you This technology can not land, this is the third point. So, we are now between 2.0 and 3.0, almost the same period from 2.4 to 2.5.
Next, we make an analogy, an analogy between blockchain and data containers.
In fact, our blockchain really has blocks. Our data is really piece by piece. Each piece is called data encapsulation. This is a bit like we put a lot of goods in this container, and then lock the container, this is called a box of goods. For us, we are called a piece of data, and then we will lock this data. The lock on us is not an electronic lock. We call it a digital lock. In fact, it is a string of numbers used for verification to be used for signature. . This is one of our forms. This is not one-dimensional, but linear and two-dimensional. Containers, there are so many boxes, or so many pieces, they are also ordered, organized, we call Organize. Just like your box is to be numbered, then your box is to be neatly tidy, you can check it when you need it, and you can find it when you need it. So this is an analogy, for a bit more fun, a little fun.
The blockchain actually has many institutions now, and many countries are also used in the logistics industry, including import and export. For example, many countries in the United States, South Korea, and the Netherlands are doing it. Headed by IBM, they have a super-books alliance, and they also offer a range of solutions that can be used by everyone. Because their technology wants to be more versatile, there are actually a lot of data inconsistencies here.
So what does it do in the field of (container)? Or, what good is it? It has to solve the problem. One is inefficiency. Dr. Zhou also said that there are too many links, and then the people involved or the roles are too many and inefficient. The other is risky because this thing is not shipped. It is risky to pay, lose or lose money, pay taxes, and clear customs.
Then if we want to use it, for example, I want to use the blockchain to try it in this field, how can we try it? I think I can make three articles around my title, the first one is for data; the second is for value; the third is for trust.
In our blockchain, first, we can do the data bearer and ensure the integrity of the data. Second, we can quantify the data, especially the quantity and value of many such goods. Our measurability; the third is that we can trust, for example, authenticity, you remember so much, remember so many words, and then so many single-sub-services, using blockchain-related techniques to ensure that it can be accepted But it is really unrealistic because people will not accept it. In fact, Dr. Zhou said that the core of this industry, we are called documents. We can e-mail the documents. This technology is very ready-made, just saying how to use it. We are also doing application innovation, so we can use this framework of distributed architecture to achieve this electronic issuance of such notes or documents. But why is it not purely distributed or purely decentralized? Because of efficiency issues. Centralization efficiency is good, so he still has a data center placed there, and then the index of the data, the summary of the data, the keywords of the data, the hash of the data on the chain, so that people can be very fast, very Efficiently find the relevant data above, and then go to the original data center to get the original data.
At the same time, we can use the blockchain to implement this digitized sequence of processes. So you will look at the picture just now. The original picture has a lot of small arrows. It is actually talking about a sequence, just the picture. It's actually talking about the order, you can take the next step to do the next step, we call it timing. In fact, the blockchain can record and string these steps, and then tell you, now the entire business or the whole of our logistics is going to where it is, where is it stuck, and then how to go in the next step? Conditional judgment. How do the blockchain judge the conditions? Blockchain 2.0, support contract, right. So what is the contract? It is the program. I can write the program, what to do next, the blockchain can do this. In other words, in fact, many times we are concerned about timing, order. Where is the difference here? For example, this is what happened in a few months, and when the matter happened, this is absolute time. But many times, we are concerned about the relative time, who is who develops before and who is after whom, this logic or this real transaction makes sense. Just like you have to work first and then get paid, this is generally normal, but it is abnormal after working first. So this order is very important.
In addition, we can implement the submission and inspection of documents based on blockchain. Because you have data to always give people a home, you can find it when you need it, the blockchain can be done very quickly. In our words, the quick meaning is that its time is not exponential growth, not linear growth, we are talking about the size of the data (to grow). And when it comes to constant time, it means that no matter how much data you have, I can find the required data between the constants, and then check and verify that it is very efficient to submit and check the data. He has an ID and then has an electronic signature, and also checks the information. This blockchain is readily available.
The last one is that we can use the blockchain to implement this kind of supervision and management service for multiple roles, which means that you may be the owner. You may be a buyer, a seller, you may be a transit broker, you may be a carrier, you may be a customs officer, you may be in any role. So how can you have so many roles in the system? Because these roles are called users in our entire system, then the users actually have different ID addresses, ready-made. Just like the currency now, what is your wallet address? How do we ensure that different users have different permissions? We actually use certificates, we call Certificate, e-Cert. The more popular ones are passwords. Of course, now we often use multi-word authentication, which means that in addition to the password, you have to have a verification code or what character you have to identify, in fact, we use a certificate here. Certificates can be used to implement the setting and probability of this privilege for different roles.
Then all these things are put together, in fact we can transform the original process into a blockchain-based process. But this picture I just said, borrowed from a document. This may be just a general or a typical existing process, in fact, all of us or all of the roles can be in different blocks or different stages, with different blocks of blockchain. Is the data package to deal with, to achieve the whole process, to achieve the whole around the goods or around the entity, you are a box or a bag, we have to surround the virtual and electronic around the entity Data management and query verification This is a whole, we call it a typical system solution.
But this system is actually in use now, but it is not used for container management or for doing this import and export. What are we actually doing with this system? We are doing traceability of some of these items, such as typical clothing or food, where is it produced, and then through which links, then who is the wholesaler, who is the retailer, where is it, and then Have you ever retired or sold it to someone, and then did you go back to repair or have a return? In fact, our system is doing this. But this is no different because for us, these are all data. In fact, the data itself does not know what it means. The data itself is a character and a binary. So now we are running some of the green systems below, but it is a layman for this product.
So today, I am also grateful to all the invitations, and I will take the courage to take our set of things and put them in a new scene. This is called application innovation. The purpose of our 3.0 is to use it in more scenarios, and to use the effects, use the performance, and then use such an impressive, or acceptable, result.
In the end, we return to our title, because my title says, the blockchain data container usually has a trusted notary, and each of these is actually meaningful. For example, the data container, which is actually implemented or for a specific scenario, such as the production and sales scene of the clothing we just mentioned, is actually the electronic standardization and intelligence of the data. This involves a lot of existing and popular technologies. For example, if there is more data, how do you analyze it? Here we will use data analysis, data mining and even data modeling methods. Data modeling that you may hear often is machine learning or deep learning, so this is part of intelligence. Standardization you are all experts. The pass-through transport line actually implements this automatic persistence and metering, but these three words have been discussed in general. Finally, trusting the notary, it realizes that around the authenticity, anti-counterfeiting and traceability of the data, it is not only reliable but also usable to build such a thing, not only usable, but also usable, not only usable, but also It is a system that is easy to use.
Finally, I am very grateful to everyone for spending more than 20 minutes. I am listening to my own industry or my own circle as a layman in this industry. I think we have to make the entire smart container to establish its industrial chain, ecological chain, value chain, etc. I think this is completely inseparable or impossible to leave information technology. Because a while ago our country strongly advocated that we call internet+, Internet+, in fact, it is now more accurate and accurate. It should be called information technology+. Otherwise, the internet+ you said may be artificial intelligence+, and then the future is Big data +, but they are all called information technology in our business, that is, Information Technology. Therefore, we are very eager to have the opportunity to use our knowledge in the field of information technology, and the meager ability to make a combination with everyone in the industry, including the specific and typical application scenarios, to truly realize our industry. A transformational upgrade of our industry. Then we realize the industrialization of our entire country called the industry 2.0 or the country we call the information age. Ok, thank you all.
