Wuzhen·Huawei Zhang Xiaojun: Blockchain is to save costs, not to generate revenue

On the afternoon of November 9, at the "New Potential Energy, New Decade" of the "2019 World Blockchain Conference·Wuzhen" sub-forum hosted by Babbitt, Zhang Xiaojun, the head of Huawei's blockchain, published "chain value, credible Trading" keynote speech.

Zhang Xiaojun said at the meeting that Huawei's core point of the blockchain is the word “chain value, credible transaction”. At present, the industrial blockchain has reached “union attribute”, “cost saving” and “focus”. The three major consensuses of the scene. According to the garter curve, Zhang Xiaojun also predicted that the blockchain technology speculation in 2019 is already in the end, and it is likely to experience a rebound by 2020. Therefore, the three years from 2019 to 2021 is the key to the success of blockchain technology.

In addition, Zhang Xiaojun also introduced Huawei's layout in the blockchain field. To date, Huawei has 26 blockchain patents covering cross-chain, distributed storage, and fragmentation. And its recently announced Beijing directory chain system has realized the chaining of more than 50 commission offices (city public security bureaus, municipal tax bureaus, etc.) in Beijing, and will access information of 16 districts and counties in the future (already connected to 3 ).

Speaking of the future development direction, Zhang Xiaojun said that Huawei has added a terminal layer to the original three-tier architecture. Huawei is more hoping to cooperate with its partners to jointly develop the blockchain and jointly maintain the entire blockchain. The rhythm of industry.

The following is the live speech of Ben Fisch, organized by Babbitt.

Zhang Xiaojun: Hello everyone!

Let me talk about how Huawei does blockchain. In fact, it is very simple. The core point is the word "chain value, credible transaction". This is the focus of our blockchain.

In fact, until now, Huawei is mainly concerned with the alliance chain, because we are concerned with how to use blockchain technology in the real economy to effectively solve the current barriers, including data barriers, including what we may have in the transaction process. False contract.

Three-point industry consensus in the blockchain industry: alliance attributes, cost savings, focus scenarios

In 2019, the blockchain industry basically reached three clear consensus points:


First, the blockchain is basically partial to the alliance attribute in the application of the real economy, and must be formed by many manufacturers.

Of course, there is a fundamental point in the alliance attribute, which is to be based on the relevant trade. Because the current blockchain is still relatively expensive, its cost is now more expensive. You are not doing it now. You have a deal in it. What does this deal cover? Covering the data, covering the money, this is the alliance attribute you can form now.

Second, the blockchain is mainly to save costs. Once a company asked me if we "use the blockchain, can we invest 5 yuan now and earn 50,000 yuan in the future?" I said that you are speculating on coins, except for the large-scale fund-raising model of the speculative coin model, blockchain In the real economy, it did not lead to a large increase in revenue, which can only be said to be cost savings. But cost savings are very beneficial to the development of your later business;

Third, focus on the scene. The blockchain scenarios are relatively straightforward. Now the blockchain scenarios are generally around a few: logistics industry, financial logistics, logistics industry derived financial logistics, financial logistics and Mr. warehouse receipt pledge. The financial sector involves payment and liquidation, and payment and liquidation involve policies. In fact, we can find that the blockchain has clear objectives in the scenes of various fields, but the focus is how to realize the settlement of trade. Simple, fast and safe is its fundamental.

Standards are accelerating, open source is converging, 2B applications are the focus

From the industry point of view, blockchain at present, everyone is biased towards open source, because it is a new technology, everyone wants to take open source to accelerate the maturity of technology. So open source has two major factions, one is the Ethereum faction, and the other is the Hyperledger faction.

In terms of enterprise architecture, the industry generally relies on the alliance chain and Hyperledger.

Second is the standard. The standards are divided into two categories: one is an international standard, and the other is a domestic standard. Among them, international standards are promoted around the framework standards of the blockchain and vertical industry standards, while domestic standards are biased based on certain The standard of the enterprise or the evaluation criteria of a scene is the main one.

Starting from the end of 2019, the standard is very high in China. Now China has set up a national blockchain standard committee under the National Standards Committee. This standard committee has a high level, which is equivalent to the national standard committee and directly puts the dimension of the blockchain. It is mentioned that with standards, there can be interconnection and interoperability, which can pave the way for the future commercial application of the blockchain.

2019-2021 is the key to the success of blockchain technology for 3 years

We also looked at the garter curve of 2019. Why did this blockchain technology talk so fast this year? First, everyone thinks that China's blockchain technology and foreign blockchain technology are basically on a horizontal line, but China's blockchain technology is relatively more oriented, and everyone at the bottom is making up. The blockchain in the United States is relatively low-level and cloud-based, and the two layers are mainly used. But overall, the blockchain is basically technical, and China and the United States basically run on a horizontal line.

In this case, China's blockchain can form a relatively curved overtaking in the context of the integration of other technologies. In the Sino-US environment, there is a good point in technical competition.


At the same time, from the garter curve, the technical speculation in 2019 is already in the end, and it is likely to experience a rebound by 2020. So who has the advantage of the underlying technology in this bottom, who has the right to speak in the future, so 2019 to 2021 is the key year.

Information technology convergence will better build a solid base for the blockchain industry

Why do you want to enable 5G, AI, and big data in the blockchain? Because of IoT, it can effectively improve the reliability of current uplink data, which is the goal of blockchain + IoT. With blockchain +5G, 5G of large bandwidth and low latency guarantees network bandwidth issues for your deployment on the edge side blockchain. Going up, is there any data for big data and artificial intelligence? Yes, but the data is messy, and a lot of data is untrue, so they want to take the blockchain as a backtracking of the relative authenticity of the data. In this case, the blockchain adds AI and artificial intelligence, and the analysis of big data analysis and artificial intelligence in the future is more accurate and more compatible. So the blockchain acts as a base and works better in this direction.


IoT is to ensure that the data before the chain is unforgeable. In fact, the deepest IoT intervention is traceability. The traceability of a product is one line, one product, one code, including the customs certificate. The pass is to use some goods directly. Digitize the pass, the pass certificate from the customs to the tax warehouse, and then all the customs clearance, including your reconciliation, one-stop use of the pass to do, use the blockchain to solve the problem.

The AI ​​has to say that the blockchain is the guarantee of the authenticity of the AI ​​analysis. This is one aspect. At the same time, if there is a corresponding data problem in the AI ​​analysis, it thinks that there is a deviation, and after the data traceability can be effectively performed, which part of the data is guaranteed to be biased in the data analysis, they can be used for data aggregation. Because it used to analyze the progress of massive data, but the analysis is biased, it is unclear what is the data. So it has two aspects: the first blockchain + AI is to strengthen the authenticity of the data, and at the same time, the AI ​​is the corresponding result. If the future is not accurate, you can also go back through the traceability of the blockchain. There is a problem with the data. So now the function of blockchain + AI complements each other more and more, and the blockchain + AI is inseparable from the future development rhythm. We also hope to do this work and link it.

Next is 5G, in fact, I did not want to understand the 5G+ blockchain, because 5G has two points: one on the UE side, this one we only see two scenes: one is the tracking of the mobile phone, it is linked with the core blockchain In the future, it is easier to track mobile phones in the future, but this thing is more useful for the security department, which is on the 5G UE side. In pure 5G, if it is based on its high mobility, high bandwidth, low latency, it is more difficult to implement on the cloud side, so I suggest that it may be placed on the edge side, which is the edge BCS node of the current BCS, so that your As the blockchain node increases, there will be a large number of interworking requirements between nodes. Because the edge side can completely transmit technology by mouth, it can replace the current 5G transmission, which may be a better solution. We believe that the 5G+ blockchain will be smoother in this piece.

Huawei's layout in the blockchain field: has achieved more than 50 commissions in Beijing

From 2015 to 2019, we have been doing the layout of blockchain technology. Recently, we have seen that Huawei has 26 patents. The first patent involves cross-chain, followed by distributed database (how to effectively store blockchains) ), there is also a shard, everyone listens on the public chain. For example, Ethereum designed the shards to increase performance. We hope to add the sharding ability to the alliance chain. In addition to the chip as a performance blessing, we improve the performance of the alliance chain through chain technology.

This is a pure cloud platform architecture. Basically, from four aspects: ease of use, high performance, high reliability, and high security, security is very important because security is fundamental. If the security and performance are not good, the blockchain overall platform will not be used at all, and it will be very heavy when it is commercialized. Therefore, we are now paying more attention to the high-performance and high-security platform architecture. This platform contains four levels and six. Modules form the overall security architecture model.


This piece is what we are currently doing in the interoperability, addressing the need for large-scale application.

We only talk about one case, that is, the Beijing directory chain system issued last Wednesday, which was officially released on Beijing TV Station two days ago. It has realized more than 50 commission offices (city public security bureaus, municipal tax bureaus, etc.) in Beijing, 44000+ data items, 8000+ responsibilities catalogue, 1900+ information system, 2.7T data sharing, and 16 futures. The information access of districts and counties (already connected to 3), so that the entire Beijing has formed a large time stamp, the Beijing Municipal Committee can see the city's time stamp. Now that the data of various departments have been opened, it has truly realized that the common people have less errands and increased the superiority of the people's livelihood through the blockchain. This is what we are doing now.


The future development direction of Huawei blockchain


The back is what we want to do. This picture has been seen before. There used to be only three layers. This year, we added another layer. That is, we have to add terminals. As the input port of our data, plus the network, the network must ensure that the entire blockchain is now not only 5G. We know that the blockchain is under the P2P network architecture. In the commercial case, in the real economy, the network bandwidth and delay pressure are relatively large, so how to adjust the network architecture? We are pulling some professors to discuss this direction. Platform + network + terminal + core, we believe that the future blockchain is definitely not just a platform, it is an integration project, in order to form a guarantee for the trust mechanism of the blockchain, this is its fundamental.

Because Huawei does not do business, we are more willing to work with partners to manage the development of the blockchain and jointly maintain the rhythm of the block industry. Therefore, we hope to work with the industry. We will work together to develop the blockchain and achieve a win-win situation for everyone. Thank you!
