On the evening of October 16th, Ultrain Co-founder & CEO Rui Guo was the guest of the “Zinc Link”Zinc Party No. 40, who explained online the road of the blockchain public chain commercial landing and shared the development direction and strategy of Ultrain now. The following is an online sharing record, welcome to read:

Q1: The Ultrain is positioned as a commercial public chain. On April 15 this year, your main net was online and the three side chains have been commercialized landing. Combined with the case analysis, What role does Ultrain play in actual landing scenarios?

In the actual landing, the Ultrain provides the enterprise with the ability of blockchain service. This ability is that after the data is uploaded to the Ultrain, it cannot be tampered and cannot be destroyed. By applying this capability, enterprises can build a trust center at a very low cost and design a variety of different business models.

We serve a wide range of industries including new retail, logistics, energy, healthcare, advertising, philanthropy, gaming, and data markets. Let me give three examples of business model enhancements by using Ultrain.

The first is an example of a carbon emissions trading based on blockchain, and we are working with a new three-board listed company.

The company's main business is to provide biomass energy, which is to replace the coal with wood, wheat straw, etc. to replace the coal, a replacement upgrade of fuel, which has been identified by China as a zero-carbon technology in the past few years. It can effectively save energy, reduce carbon emissions and protect the environment. In the process of energy supply, they can count the carbon emissions saved, trade the reduced carbon emissions on the carbon emissions exchange, and generate a new income for the company.

The problem with this new business model is that the boilers they supply are basically small boilers, such as 6 tons, 8 tons, but the carbon emissions trading is basically 500,000 tons. Therefore, they need to collect all the emission reductions of the boilers after combustion, and carry out batch transactions between the unified and carbon emissions exchanges.

But who is counting this data? If the company's own system to count, the carbon emissions exchange will not recognize, because the company itself may modify the data; if you find third-party statistics, third parties may collude with the company, it is not credible; According to the Carbon Emissions Exchange, it is difficult for the company to trust the exchange. In the traditional business scenario, this business model requires a very high cost of trust to be established.

At this point, the zero-cost trust capability provided by the blockchain technology can solve this problem well. Ultrain and the company have teamed up to develop a carbon blockchain solution. The company's boiler is equipped with an IoT device called a thermal mass spectrometer to record the amount of boiler burned per day. We can use wireless transmission technology. The heat data of the combustion is directly written to the blockchain by the device and stored.

Through this data, it is easy to calculate the carbon emission reduction. Due to the non-tamperable nature of the blockchain, parties involved in carbon emissions trading can determine that the data is true, effective and reliable, and the business model can be implemented.

The second example is the first customer we worked with, yoho!

Yoho, it is the largest B to C tide brand e-commerce trading platform in China. They launched the vertical category of C to C shoes trading service at the beginning of this year. The sneakers trade should be familiar to everyone in the last two months. Yoho was started at the beginning of this year work with us.

After the buyer purchases the sneakers on the platform, the seller sends the sneakers ordered by the buyer to the platform, and the appraisers of the platform authenticate the shoes. After the authenticity is determined, the anti-theft buckle is added to the shoes, and the non-damageable NFC is pasted on the buckle. Label, then upload the shoes information and transaction information to the Ultrain chain. After the buyer gets the shoes, the genuine information written by the mobile phone can be inquired; and many buyers of these limited edition shoes are not worn after buying, but will be traded again.

Buyers can sell sneakers on larger platforms, such as idle fish. After the new buyer gets the shoes, you can download the YOHO app, check the truth and confirm the ownership of the shoes.

For new buyers, because he wants to trade again, he has a great driving force to download the app and upload transaction records for value preservation. For goods, this is a free platform from the big platform. The process of directing free diversion; thus saving market costs for goods and achieving better results.

In the third case, let me introduce you the decentralized board game that we cooperate with the electric soul blockchain laboratory.

Electric Soul is an A-stock listed company that has developed many famous games. The company is located in Hangzhou and is close to the Ultrain headquarters. For online chess games, one of the core pain points that plagues such games is the fairness issue. Since the chess game is run on the server provided by the game developer, the game developer has the ability to control, for example, the card. The order of the cards to influence the outcome of the game to make a profit; for example, for Texas poker, you will find that the chance of AA to KK in online games will be much higher than that of offline games, because gamers have strong interests. Drive to control the board to a similar situation, and profit by washing as soon as possible.

In order to solve this pain point, Ultrain and Unitopia jointly developed a blockchain Texas poker game. The biggest feature of the game is that the program logic of shuffling is controlled from the original black box of the centralized server. The intelligent contract control on the blockchain, because the blockchain technology can not be falsified, and is transparent to everyone, after this transformation, the shuffled card order will not be controlled by anyone or game developers, is completely random.

This is a complete solution to the core pain points of traditional online chess games. I believe that all game users who understand this change will be more interested in this decentralized board game.

Through these three examples, you can find that although the actual application scenarios are very different, the core of trust computing is still a low-cost trust center. This is why we believe that blockchain technology can bring business to the market. Value-added and upgraded places.

At the same time, we can see that this kind of trust ability can be applied to help enterprises to reduce costs and increase the income of the scene is very extensive.

Q2: What are your main competitive advantages compared to other public chains? What innovations in the business model? In the process of the entire commercial landing, what are the biggest difficulties and obstacles encountered? How is it broken out?

Ultrain's vision is to provide a decentralized commercial infrastructure that drives blockchain technology to empower the real economy and help the real economy create more value.

Compared with other public chains, our competitive advantage is mainly reflected in three aspects:

First, excellent theoretical innovation ability. It includes the R-PoS consensus consisting of the world's original and implemented stochastic dynamic fragmentation technology, the world's original two-layer random number generation architecture, and the world's only blockchain 3.0 public chain that integrates the zero-knowledge proof privacy protection scheme. These three technologies are the first to be realized by Ultrain on a global scale, and so far we are the only team in the world to implement these technologies.

The second is the rapid implementation of the landing. The Ultrain main net was officially launched on April 15, 2019. It is the earliest public online link in the global blockchain 3.0 public chain. Now there are 400 miners in China, Europe, the United States and Australia. The provided node provides external services.

Our main net has the following characteristics: high performance: completely decentralized network, no super nodes; single-chain TPS 1000, 50 times Ethereum; confirmation time 10 seconds, 1/12 of Ethereum; acceptable use Cost: 1/20 of the cost of Ethereum; a complete privacy protection solution: Provides a programmable zero-knowledge proof privacy scheme that can customize arbitrary data and arbitrary logic according to the user's business logic.

The third is the expansion of rich business resources. Ultrain has strong business development, capital and ecological building capabilities on a global scale. After completing the main online line in April this year, we concentrated resources on the promotion of blockchain technology. Currently, on the main net of Ultrain, we have deployed applications including new retail, logistics, games, energy and other industries. More than 20 companies in the pipeline are communicating, negotiating, docking and debugging with us. At the same time, on the to C side, we also try on the social e-commerce field based on our own commercial resources.

These characteristics are achieved thanks to a comprehensive team capability. First, the founding team has strong academic and engineering experience. We can not only propose innovative theories, but more importantly, we can put them on the ground quickly and efficiently. The team is now nearly 50 people, 80% of whom are technicians, half from the Ant Financial blockchain team, half from the Alibaba Cloud OS operating system team, and some from Huawei and ZTE's core network and routing protocol teams. The team has extensive development experience in blockchain, artificial intelligence, IoT, and operating systems.

I have 10 years of working experience at IBM. In 2013, I went to Alibaba as the technical director of the security business group and was responsible for the entire data team.

Before joining us, CTO Li Ning was the technical leader of the Ant Financial Blockchain team and led the team to apply for more than 30 blockchain patents. Chief Architect Shen Yufeng previously served as the core architect of Google Canada ChromeOS and Alibaba Cloud OS. Wang Husen, the chief architect of the core cryptographer, was the only cryptographer of the ant Jinfu blockchain team. He has been involved in related research in Europe's top cryptography research institutions before joining ants.

Our Chief Strategy Officer, Emma Liao, has extensive international work life experience and strong cross-border resources. During her many years of professional career, she has accumulated a large amount of cross-border Europe through investment and cross-border M&A work on Wall Street and Europe. The core resources of the United States, Israel and other regions have received an invitation from Zhou Hongyi to return to China as the general manager of 360 hardware investment in the past 15 years. The follow-up has been engaged in investment and financing in the country, so that Ultrain has a large number of top-level resources for business and industry in the world. Quick docking can promote the blockchain to empower and land in traditional industries. Li Jin, who recently joined the team's chief digital officer, worked in Microsoft for 20 years and worked in Ant Financial for 5 years. He is the general manager of Ant Technology's global technology strategy and has abundant resources in the global technology ecology.

The above is the embodiment of our Ultrain in terms of competitiveness.

In the business model, Ultrain adopts the light economy operation mode of sharing economy. The trust computing nodes (that is, ordinary servers) in the Ultrain network are provided by people. The Ultrain network integrates the CPU computing power of these servers to form a trust computing service. Sold to the enterprise, the enterprise calculates the payment service fee for the trust purchase, and 80% of the service fee is automatically transferred to the public who provides the server, and 20% of the service fee is paid to Ultrain. The service fee paid by the enterprise adopts the prepaid system. The enterprise needs to pay the service fee for one year in advance, and the service fee is locked in the smart contract. The smart contract will automatically perform the service fee allocation according to the above criteria.

The usage fee paid by the enterprise to the Ultrain trust calculation will be recharged in the account that the Ultrain main chain is automatically managed by the smart contract. The smart contract will automatically deduct the corresponding amount in the enterprise account according to the actual computing power provided by each computer. Transfer the account to the computer owner's account.

In the process of commercial landing, the biggest difficulty we encountered is also the obstacle often encountered in enterprise services, that is, the progress of project cooperation development is not easy to grasp.

This is the only virtual elephant on the line. The physical elephant is accompanied by an NFC tag that records the unique number of the elephant, which is recorded on the digital elephant on the chain as the unique identifier for each digitally generated baby elephant. Each digital elephant has its own attribute: the energy value, and its initial attribute value is the same. Ultrain elephants can be traded, given, transferred, etc. between accounts.

Then we will release the UIP09-based Ultrain T-shirt. Like the baby elephant, each T-shirt will have an online version, and the online digital T-shirt can be worn on the online Ultrain elephant. The image of the elephant will change and become the image of the T-shirt. At the same time, the T-shirt has a special ability to randomly increase the energy value attribute of the elephant attribute 10 - 30 points, thus the same The elephant image is differentiated. Some small elephants have high energy values, some have low energy values. Some small elephants use multiple T-shirts, and the energy value may be much higher than other small elephants;

Subsequent products that we sell, or other merchants, including red wine, luxury goods, etc., will have similar properties, which can be combined with small elephants. Finally, each elephant may form a unique form. Among them, there are rare elephants, including online assets and offline assets, which will have a good collection value. These elephants can also be linked with other applications, such as the game "Encryption Three Kingdoms" to be released on Ultrain. In the middle, the elephant can be imported as a pet prop. Of course, the elephant with high energy value will have better attributes in the game. In this way, the elephant will have better transaction value and increase the value for the user.

Q6: You defined the protocol specification UIP09 for the blockchain digital twins on the Ultrain platform, and released the digital twins Ultrain elephants based on the UIP09 specification. In addition, what new attempts? What are your plans for the expansion of the business ecosystem?

First of all, in the aspect of to C, we will continue to try on social e-commerce. On the one hand, we will carry out self-employment and sell more goods. At the same time, we will carry out investment promotion, welcome more platforms and merchants to enter the platform and sell social e-commerce. Attempts, secondly, we will do more trials and applications on the C side, and we will further cooperate with large and medium-sized enterprises to further promote the development of blockchain business in new retail, charity, logistics and other aspects.

Wonderful interaction

Q1: What amount of digital goods can you support?

In fact, each department does not take out the data. Each department acts as a data node, and each maintains its own data, and realizes data sharing based on business scenario driving and authorization.

Our single-chain 1000TPS, single-chain memory space is about 20G, the system supports horizontal expansion, and can support digital goods at Taobao level.

The system now has 4 side chains, which are 4000TPS and 80G memory. The system supports horizontal expansion and can support digital goods at the Taobao level, that is, tens of billions of goods.

Q2: In the case of carbon emissions trading, how to ensure the trust before the data is on the chain? For example, through the IoT device of the thermal mass spectrometer, the heat data of the combustion is directly written to the blockchain and stored. Can you ensure that the data is not modified before the winding?

We do not guarantee the reliability of the data before the chain is being chained. The manufacturer is guaranteed by the thermal mass spectrometer and the energy manufacturer. I only guarantee that the data written on the chain cannot be falsified and cannot be destroyed. In this link, there are also industry associations. A series of institutions such as the Carbon Emissions Exchange entered the supervision and audit.

Q3: What are the biggest difficulties or challenges of landing public chain applications? Which has more vision for To B or To C?

The biggest difficulty in landing the public chain is to find the core pain points and what you need to solve with the blockchain technology. This pain point must be solved with the blockchain. It can't be solved with other technologies. The pain point, blockchain technology application is very easy to land, customers will urge you to land.

To B and to C are different ways of playing, and it is not possible to answer which one is more promising. This is to see which part of the team is more resourceful and more in line with its own genes. We are also trying and groping in the process, hoping to unique.

In the process of actual landing, the project contract time of the enterprise customer, the change of demand during the execution of the project leads to the extension of the project, the project encounters force majeure and needs to be postponed, etc. These are frequently encountered problems.

What we can do is to overcome these difficulties with our customers through professional services and ensure that the project will be step by step. Enterprise services are generally the most difficult in the early 1-2 years. After completing the integration with the company, and forming a good partnership, it will go smoothly, including my early service in IBM, and many Customers have also become friends, and these friends are further supporting my entrepreneurial work in the blockchain field, which is worthy of gratitude.

Q3: You are serving the main chain of the e-commerce industry, and have already entered the trend of e-commerce brands YOHO. Compared with before, what is the current data performance?

Before YOHO was engaged in B2C business. It just started the C2C business line this year. In terms of quantity, they now have tens of thousands of shoes every day to complete the transaction on the Ultrain platform. So far, millions of shoes have been completed. On the winding trade, GMV has more than tripled monthly growth. In terms of categories, in addition to shoes, it has also expanded to T-shirts, sweaters, pants and other categories. It can be said that the business based on blockchain traceability is booming.

Q4: In recent years, digital twins has been frequently predicted by Gartner and other organizations as an important technology trend in the future. Please explain the digital twins in a more general way, and combine the experience of the Ultrain to talk about how to build a blockchain digital twins application? What value can it bring?

In the process of enterprise service, one problem we found was that the service cycle was long and the landing time was long. Because our Ultrain team had strong technical capabilities and commercial resources, we thought about whether we could incubate a block. Chain application, explore more business scenarios of blockchain application, combined with our own background, we chose the field of social e-commerce based on blockchain. In the process of doing social e-commerce, we thought, can we combine some of the technical characteristics of the blockchain to form different business models?

Digital twins technology is a technical concept proposed by Professor Dr. Michael Grieves of the University of Michigan in 2002. The more formal explanation of the words refers to the digital body that the physical entity of the product integrates into the simulation model in the information space. And related technologies for realizing product life cycle archival management using digital twins.

To put it simply, there is a physical entity under the line, correspondingly in the cyberspace, by digital means to construct a virtual digital entity corresponding to it, through the operation of the virtual entity, predicting the actual physical entity may appear In the case, this is an innovative technology that is more widely used in the manufacturing sector.

When I first came into contact with the concept of digital twins, I immediately thought of the ERC721, which is familiar to everyone in the blockchain field. ERC721 is a Token (Non-Fungible Tokens) created by Ethereum to refer to and define “non-substitute items”. If we combine ERC721 with digital twins, digital twins based on blockchain technology will What kind of goods are formed? We call this the "blockchain digital twins."

The blockchain digital twins. shortly, there is a physical entity under the line. By means of digitization, a unique virtual digital entity is constructed in the network space. The virtual digital entity and the physical entity are uniquely mapped one-to-one. The added value of physical entities will bring about the value added of virtual digital entities, and the added value of virtual digital entities will also bring about the added value of physical entities.

Of course, this is a concept exploration. We are trying to get a unique online digital version of most of the products on the blockchain social e-commerce platform we are doing now, and these products can be directly combined, assembled and consumed. destruction, the formation of some more characteristic, more scarce items, the provision of these items can be traded, thus bringing the value of these virtual items, and thus helping the value of physical goods.

Q5: What role does digital twins play in the social e-commerce industry? UIP09-based social e-commerce launched by Ultrain, the main combination of UIP09 virtual assets, what is the specific model? How to understand "combined transactions"?

Let me give you an example. We sold our first Ultrain mascot Supernova elephant during Chinese National Day.
