PwC Kris Kersey: Autonomous network formed by the integration of AI, Internet of Things, and blockchain is a promising future

At the EmTech China Global Emerging Technology Summit on December 13, Kris Kersey shared his views. Kris Kersey is the head of the blockchain at PwC's Emerging Technology Division, focusing on how crypto-assets and blockchain-driven ecosystems will affect business models and shared business processes across industries. He said: The integration of AI, Internet of Things, and blockchain technologies to form a self-healing and self-adjusting network will be a very exciting future for us.

The following is a compilation of Kris Kersey's speech, organized by Babbitt based on shorthand content.

After constantly analyzing more than 250 technologies, we slowly learned what the meaning of AI is, what is the significance of the blockchain, and what is the significance of the Internet of Things. If we want to solve a business problem, we don't have a nail at hand. Looking for a hammer, we need to integrate these technologies. We also need to invest a lot in the existing infrastructure. Only in this way can the problems of the entire ecosystem be continuously solved and constantly subverted.

Many things are emerging now, and there are some things we already know, such as extending reality, which can help us expand our living space. We can train staff by challenging them. Some jobs are inherently risky. With such advanced technology, they can train in a virtual environment.

How many people have used Siri or other mobile software to communicate? Or have you used Google or Amazon Alexa technology? The way we interact with technology is changing rapidly and profoundly. We have used sound to interact, and may use brain waves to interact in the future.

Imagine that an immersive interface is very constructive. Don't imagine it as a separate field and a separate function. Such as robots, they are integrated together to work autonomously using artificial intelligence to achieve end-to-end automation. For example, self-driving cars. Imagine that Didi has a series of electric vehicles. They can charge automatically, and the contracts are placed on the blockchain. All payments can be carried out autonomously without human intervention.

You may have heard of the concept of "digital twins", which is a mirror image of the physical world. There is also telemedicine, which enables people in remote areas to get medical services and perform remote minimally invasive surgery. Digital twins, or digital mirroring, can do these things, which is great.

In addition, there are 5G, highly connected networks, but this is not limited to 5G. We need to further expand to provide continuous and stable edge network connections. Putting all these technologies together to form a self-healing, self-adjusting network is a very exciting future for us.


When it comes to trust, trust has a high cost. Branded products or consumer products involve trust issues. According to the OECD, we spend $ 500 million a year on counterfeiting. There is also the trust of the ecosystem. For example, a doctor in the United States needs a license. There are many service providers who confirm that the doctor is qualified to practice medicine. This industry costs 2 million a year, just to prove that a doctor is qualified. Similarly, there are many aircraft companies that do certification because they don't believe in what other companies make. If we use AI, blockchain, and the Internet of Things, blockchain is like a track. Using "smart contracts" can help us better manage treaties and lines.

This is a bit like a relay race. What I need to do is take the baton from one person, and then provide the baton to another person in a fixed way. The blockchain can supervise whether we pick it up as it should Great and great. Speaking of the Internet of Things, someone is already running with a stick. I got information from IoT devices and edge devices. This information can tell me whether this person is running the wrong way or is going the wrong way. If this person runs the wrong way, then I can know what might be wrong. IoT devices can get all this information, and the blockchain ledger can ensure that the legal and financial responsibilities of the entire contract are fulfilled.

AI is at the top level. This is an invisible transaction layer. I can understand how the entire supply chain is performing, and determine if there are services or products that are running too fast or too slowly. Then I can interfere with the blockchain to better connect with the supply. The partners on the chain improve efficiency together, and this is a credible chain.

In the United States, we cooperate with many energy suppliers. In fact, there is no end-to-end transparent and traceable architecture or pipeline to help us understand natural gas transportation. In the entire process, there is an oil and gas operator, who is responsible for procurement; if there is a distributor, he will take the procurement contract, fill it, and provide it to the market, and may also take goods from the supplier; the manufacturer will Like a node in the production chain, he will get the order, then carry out the production process, and finally generate an asset. There will also be a certificate on the asset, just like the birth certificate to prove its provenance.

This chain, or connection, can be used in other scenarios. At present, the operation of natural gas still needs to be completed by humans, and all are paper contracts on paper. The process of docking with people is time-consuming. But if we can have a blockchain ledger and build an ecosystem, it can bring many benefits, including real-time information data.

Looking at the Internet of Things, if the manufacturer can give a production certificate, other suppliers and distributors can add additional information to the production certificate, just like adding other key information nodes to the birth certificate. . Maybe this asset is used in other industries, such as construction, welding, and other processing processes, can add some additional information in the production link.

This provides us with an asset custody chain, and we can see specific applications in many areas, such as the advertising industry. We can use practical technology instead of phishing pages or other inducement pages. What you may get after you click It is a pirated or counterfeit website. And under the kind of chain I just mentioned, the real information is connected, not the information of the phishing website.

This will be a real application in the field of energy. When oil and gas resources arrive, we need to lay the pipeline in advance. The construction of the pipeline is actually very important. We can also use the Internet of Things, blockchain or smart contracts to identify the qualifications of construction workers. I believe that in the future market, there will be more contractors to provide various certifications, whether it is aviation, medical or energy. For example, Uber in the United States and Didi in China. If Uber ’s driver ’s license is revoked, this information should not be made public only within Uber, but also shared with other travel operators, which can avoid many risks.

Let's imagine the chain of asset management. People, physical and digital dimensions can be connected to build a trustworthy platform. In this ecosystem, all participants are trusted entities. Of course, this is not a simple matter, because it involves more than one company. Digital transactions between multiple companies are more difficult, and not a technical problem. How to connect different systems, how to do standardization, and how to unify the incentive model behind it.

therefore. Blockchain experts, data scientists, and network architecture experts may need to sit together and discuss together, but the scarcity of talent has also caused difficulties in team formation, which is why I have always said that it is not a technical problem. Technically In fact, it is already feasible.


In addition, in the round table session, Kris Kersey further explained the application of blockchain in the supply chain scenario when answering the host's question.

If we focus on identity management in cyberspace, there are cases where you set an identity through a blockchain wallet and decide for yourself how to share your identity information in different ecosystems, so that you can meet the EU Data Protection The law requires that digital identities can be managed through the blockchain.

So in the supply chain scenario, we can think like this: If the asset is an airplane or a car, which consists of millions of parts, should we track the final product, or track all its parts? If the Internet of Things, artificial intelligence, and digital twins are all used in commercial production. The blockchain can become a general ledger that records all activities, creating an immutable record that helps us manage the information of the entire life cycle of the product.

This data can better manage the aircraft, and the time can even spread for 50 years. Even if some financial aspects or component changes occur during the process, we can correctly value, rather than saying that it has been depreciating, I think this In fact, it is a very good application area.

The other is tokenization, we can build a token infrastructure in various fields. For example, the restaurant and hospitality industry can use some kind of token, which is actually a virtual asset, which can be used for currency exchange and can also be used in the incentive system. In fact, the company we are investing in is doing this.

There are also some corresponding usage scenarios in the United States, and the specific exploration may be relatively limited, including clearing, settlement, payment, trade, and asset trading, but it does have great potential in assets, which can improve overall efficiency, but may The development speed in other industries will be faster than the financial field.

We will continue to update Blocking; if you have any questions or suggestions, please contact us!
