8 questions text version | ICT Golden Key: ID may trigger large-scale application of blockchain

From December 7th to 8th, 2019, the "Blockchain Technology and Application" Science and Technology Frontier Forum hosted by the Chinese Academy of Sciences and jointly supported by the China Academy of Information and Communication Technology was held in Shenzhen.

Dr. Jin Jian, Director of the Institute of Industrial Internet and Internet of Things of the China Academy of Information and Communications Technology, and Deputy Chairman of the Blockchain Committee of the China Institute of Communications, acted as the host of the entire forum on the 7th and conducted the "ID Evolution and Blockchain" The keynote of Gravity Singularity.

After the forum that day, Babbitt's "8 Questions" conducted an exclusive interview with Dr. Jin Jian. The topic starts from the BIF public license chain initiated by the Institute of Information and Communication Technology. After going through topics such as ID, blockchain, Internet of Things, and industrial Internet, it ends up on 5G and blockchain. Come on, listen to Jun's words, and read ten years.

ID may trigger large-scale application of blockchain

Jia Xiaobei: What is the background of BIF's launch of this public license chain?

Golden Key: We have been thinking about it (BIF) since the second half of 2016. Our country is now promoting the Industrial Internet, which is the Internet of Things as people understand it. From the relevant documents of the State Council, we can see a very important thing, which is the Industrial Internet logo, or the Internet of Things logo.

The Industrial Internet of Things logo can be understood as: As the machine becomes more and more intelligent, the machine can interact with itself. In this process, it needs identity authentication.

In the process of identity authentication, we found many problems, mainly several points:

First, the ID on the traditional Internet is called PTI, which is the domain name. It does not support the heterogeneous, heterogeneous, and heterogeneous needs of the Industrial Internet.

Everyone knows that the system connection logic in Industry 4.0 has completely changed, and it is necessary to interact from one system to another. Many teachers talk about supply chain collaboration today, and there is no way for domain names to accomplish this, because domain names are simple consumer logic. Therefore, we use some existing technologies, such as OID and TS1 coding, as well as Internet payment technology systems, such as Handle, which have been promoted globally for more than 20 years.

After the rise of the Internet of Things, it is believed that these new technologies can solve the needs of the Internet of Things. There are two points: One is that we are already trying to use new technologies and standard systems. We are trying to apply it to the current scene and see if it can help the development of the Internet of Things and the Industrial Internet.

In addition, the new technology of blockchain provides a very good solution for us to handle point-to-point connections and transactions, and is a very good model. That's what I said today, and you can achieve true Internet of Everything. It is not a purely technical problem, but what to do after the connection is to solve the transaction logic after the connection.

For example, the direct connection of our two mobile phones, in addition to sending documents, can also communicate, make transactions, and settle accounts. This is the economic interest relationship. The mobile phones at both ends become two independent identities. In this section, we see the role of the blockchain on ID. In order to do a good job of this new ID logic, we launched a public chain called "BIF" in the second half of 2016, but it has not been fully open, so it can also be called the alliance chain.

We hope that in the new and more digital space, BIF will be able to construct ID things, build a new digital framework, and provide this system. The Internet has a model of information consumption consisting of domain names and IP addresses. But in the new era of the Internet of Everything, there is no similar model, so it is a very important application that requires blockchain to support it.

Jia Xiaobei: Does that mean "ID + blockchain" will create a world beyond our imagination?

Jin Jian: Actually not, because in any space, trust between people is involved. This is an economic relationship. Economy and benefits will involve identity issues, whether it is humans or intelligent machines, it needs to obtain an identity. We know that the current blockchain has an account, which is an identity, which is used for people and also for machines. Smart contracts have accounts with codes, which do not need people to operate.

If the ID technology cannot be resolved, in this space, whether it is economic relations or production relations, it cannot be properly managed, so it will not appear on a large scale. Whether the Internet or the Internet of Things, especially the Internet of Things is currently limited by the dilemma of end-to-end connectivity, and now it is all about solving security and credible problems, especially the Internet. So we have the IP and 3w (website), ushering in the first climax of the development of the Internet, because ordinary people can use the Internet to obtain consumer information.

In the Internet space, this model does not provide a technical framework for the real consumption of ordinary people. This information is free. Internet technology does not support business models, and everyone in the early Internet had this problem. Many people will not pay attention to this matter, because it is technically or in the past technology field, everyone thinks it is not so important, what you see is password or contract. But we have to think about what will come to this network to make the blockchain work.

ID can solve the problem of how assets are injected into the chain. This is very easy to understand. If the domain name of the Internet solves the problem of accessing information, we now make the blockchain become an information-based scale requirement. The so-called demand has value. How to bind the value to the blockchain requires the Handle system This is very easy to understand.

This is relatively neutral on the Internet and may not be used to make money, so many commercial companies don't pay much attention. But I still want to say: ID may cause large-scale application of blockchain. With assets on it, it will definitely produce many economic models and economic values.

Jia Xiaobei: How is BIF currently progressing?

Golden Key: We hope that in the first quarter of 2020, BIF will be deployed on top national nodes. We are now collecting the requirements of some applications, as Mr. Zheng (Mr. Zheng Zhiming) said today: There are many links to make applications in the blockchain.

The application of blockchain-based identification can quickly allow some companies to see this problem and find ideas to solve this problem. Many academicians have mentioned today that blockchain is more than just digital assets. In addition to asset systems like Bitcoin that are not anchored in contradiction with actual assets, I believe that there are many more intelligent systems or equipment that can be more digitalized through the blockchain and BIF, so that they can access this chain and realize new types of assets. Let everyone see the role of blockchain. I don't think everyone can see the role of blockchain without this application.

Try to start from a small place, let everyone see the capabilities of the entire blockchain technology. Just like Bitcoin is actually very simple and very poorly scalable. But it proved the entire trust system, computing system, and trust channel, so it brought great value.

Jia Xiaobei: BIF is mainly used to solve the problems of providing identification, data, government affairs, and people's livelihood. Which organizations will participate in it?

Jin Jian: It has not been finalized yet. We hope that some universities, research institutions, and schools will participate in it, and several leading companies are now communicating. There are two types of leading companies. One is financial. It should be said that companies have accumulated a large amount of data assets. Another category is the smart manufacturing enterprises that are ahead of the Internet of Things or Industrial Internet. These scenarios can only be explored if or if the production system is highly informatized and automated.

Jia Xiaobei: Many academicians today say that "blockchain is not just a digital currency." How should we clear the source of the blockchain?

Jin Jian: In order to clear the source of such a complex system, there may be two aspects: one is top-down, and a systematic overall analysis is performed from the whole; the second is bottom-up, and the technology involved from a local perspective For a deeper interpretation.

Because many people do n’t understand why there are so many people doing blockchain, why are so many people obsessed with issuing coins? From the perspective of cryptography, the development status of the entire industry, privacy protection, and the evolution of ID, etc., the problem is clear, and everyone can find a better way to create value.

The combination of blockchain, 5G, and the Internet of Things ushers in the true interconnection of all things

Jia Xiaobei: After 5G is fully popularized, will there be an explosive growth period for blockchain and the Internet of Things?

Golden Key: I have seen many research reports that 5G is a catalyst for the Internet of Things and blockchain. 5G has three characteristics, one is enhanced mobile bandwidth, the second is large-scale machine connection, and low latency and high reliability.

5G is probably not prepared for us humans. The main application of 5G is on the battlefield of the Industrial Internet and the Internet of Things. If 5G needs to be able to network as needed anytime, anywhere, it will be the basic communication connection to realize the interconnection of all things.

But how to do it on the connection? It may require an end-to-end computing model like blockchain to manage transactions and complete transactions for two connected devices. The blockchain is likely to provide a ledger for 5G and the Internet of Everything. This ledger manages two Interactions and transactions between devices.

Because blockchain and bitcoin are payment systems, if value transfer or payment is needed end-to-end directly, blockchain can provide this value capability.

Speaking of the privacy protection provided by the blockchain today, a large number of devices are involved in access. In fact, the future of Internet of Everything or 5G opens the era of Internet of Everything. People are connected to the network anytime, anywhere. Now we are thinking more about holding a mobile phone to access the network. In the future, we will use a car, refrigerator, or any terminal to access communication … How to protect your information and device information?

The asset management and privacy solutions on the blockchain will become more and more complete, just like the way from telecommunications to Internet use. Calling WeChat in the past has made the experience better and better, but the underlying technology has not changed. So I believe that the combination of blockchain, 5G and the Internet of Things may be able to converge to form a truly connected world. It is not just a technical connection. It requires transactions to drive the generation or realization of this value.

Jia Xiaobei: How big is the relationship between 5G and blockchain? Make a simple metaphor.

Golden Key: If 5G and blockchain are the catalysts for the Internet of Things, on the other hand, blockchain can find content for the 5G business model.

We say that 5G changes society, but how to change society, how to apply such a large investment to the Internet, and how to make it a new value? For example, a 5G independent network is built, and this investment is very large, including to the terminal. 5G provides models with high reliability, low latency, and large-scale machine connections. Blockchain can provide at least inspiration for 5G's business model. In the future, 5G base stations will mature. In the entire scenario, the blockchain can complete end-to-end transactions, Communication.

Some people say that without 5G, there will be no Internet of Vehicles. The true Internet of Vehicles, and transactions between cars and cars, except for 5G, such as high-reliability, low-latency communication, how to operate without a blockchain, can not operate. So this is called mutual fulfillment.

Jia Xiaobei: What is your biggest expectation for 5G?

Golden Key: My personal expectation is to own a 5G mobile phone, and the biggest expectation is that 5G really realizes the interconnection of all things.

I can say some specific scenarios. Everyone knows where to meet now, or where to go. The connection between your device, computer or mobile phone and the projector in the conference room is actually very complicated and very inconvenient. Sometimes you feel slow, sometimes you feel unreliable, and you feel that the connection is unfriendly, and non-technical people cannot complete this operation at all.

Now the two of us are connected to each other's mobile phones, and using Bluetooth or wifi is actually more complicated, not as convenient as our call. I believe that 5G will soon bring a new experience to our lives, and the interconnection between devices becomes more and more convenient, and you can do more things.

5G can also be understood as the infrastructure of a new type of network, which is more powerful than the previous network. Just a few points, whether it is bandwidth, connection management, or networking capabilities, networking capabilities are everyone talking about 5G slicing. The new infrastructure provided by 5G will definitely make the application of smart cities easier. . Because the infrastructure is upgraded, just like the high-speed rail tracks are upgraded, the trains are faster, saving us a lot of time.

Jia Xiaobei: Do you think that the biggest application of blockchain in the future is in the Internet of Things, or is everyone optimistic about finance now?

Jin Jian: Quite difficult to answer this question.

First of all, about the blockchain, I remember the co-founder of Ethereum said: Music, copyright, scientific research activities, and IDs may be easier to solve for the blockchain.

Digitalization in the financial field is very complete, whether it is cross-border payments or the entire digital currency system, because money is a number, and after the currency is issued, the numbers can enter the record. Therefore, in this respect, distributed ledger books can be used to solve cross-border payment problems, or supply chain finance. These financial scenarios are relatively easy to provide solutions locally.
