At the end of the year, the status of blockchain technology has come to a big turn and is positioned as a strategic technology. It is expected that in the new year, the blockchain will usher in a better development environment. For companies doing the underlying technology of blockchain, there may be more projects in both To B and To G directions. Landing opportunities.

Like the Tiger Sniff Pro team said in the “Block Chain Landing Case Full Analysis” column, the application of the blockchain is no longer a castle in the air, but indeed Some landing applications, such as supply chain finance, commodity traceability, asset securitization, credit management, e-government, copyright management, cross-border payment, etc., have already been applied in the chain. However, the scale of the blockchain application is still small, and the application of the blockchain is still facing difficulties in transaction capability, privacy protection, and enterprise informationization.

On the November 23rd Tiger Sniffing F&M Innovation Festival, the ant blockchain technology director, Dharma Institute blockchain senior technical expert Yan Wei on the core of the blockchain The value, application scenarios, and landing challenges have been thoroughly interpreted.


The following is Yan Yan’s speech (with deletion):

Hello everyone, I am very happy to be here. I will combine the experience of the ant blockchain in the process of empowering entities today to introduce to you where the core value of the blockchain is, where the main application scenarios are, and the future. What our life looks like.

Blockchain build value Internet

What is the core value of the blockchain? It is to solve the problem of trust.

In the past 20 years, we have witnessed the prosperity of the entire information Internet. Two strangers in the world don’t know each other and can easily transmit texts, pictures and videos through the Internet. Because of this convenience, we have a new business model, e-commerce, social networking, and so on.

In the information interconnectionAt the upper level of the network, we have seen a layer of value network built with blockchain technology. Several companies can use such a network to efficiently and credibly transfer digital assets such as bills, contracts, and accounts receivable. .

The smart contract itself is a very complex function in the blockchain. It acts like a gear, allowing the parties to promote seamless cooperation and professional distribution between people, machines and institutions. In the end, a trusting and extremely efficient contract society will be built.

I will give an example of an image. Now I use APP for travel, all cities have their own apps, Shanghai has its own subway app, and Hangzhou has its own subway app. The problem has arisen. If a person travels from Hangzhou to Shanghai, he can’t use the Hangzhou subway app. Ok, we want to work with APP. However, there are several issues involved.

First question, how many people will go from Hangzhou to Shanghai, or from Shanghai to Hangzhou? The second question is that Shanghai users take the subway in Hangzhou. This service is provided by Hangzhou Metro. The money is collected by Shanghai APP. How to settle?

Today, it is because of the blockchain technology that builds an interoperable network, where you or yours, my or mine, on this basis to achieve the settlement of business results. The Yangtze River Delta has already tried to achieve this kind of interconnection, and it uses the technology of Alipay blockchain.

Three large-scale landing scenarios for blockchain

Because I believe it again and again, I see it. In the past few years, the ant blockchain has been pushing for valuable commercial applications. I will give you a share of the three typical scenarios in the industry.

The first example is an electronic ticket based on a blockchain. What is the difference between blockchain-based electronic bills and traditional electronic bills? There are three differences.

1, based on the bottom layer of the blockchain, can prevent tampering. The blockchain will be generated in the electronic ticket,In the whole process of transmission, storage and use, it is covered with “poke”. The fake ticket is made true again. There is no “mark on the chain”. It is also fake and very easy to find. Therefore, in the process of the company’s financial verification, no complicated detail inspection is required, and the bill data can be directly retrieved from the chain.

2, traceable. There is a problem with the ordinary invoice, and more than one ticket is reimbursed. This “reimbursed” information is recorded on the blockchain and is traceable, viewable in real time, and prevented from fraud. Taking the well-known insurance scenario as an example, the participation of blockchain can speed up the claims process of insurance companies.

How to achieve this credibility? During the overall circulation of the bills, the hospital, the Finance Bureau, the Social Security Bureau, and platforms such as Alipay are all nodes on the chain, achieving multi-party consensus and building a trust foundation.

3, cost issues. For example, the traditional tax-enterprise direct platform cost has remained high: According to the estimation of a city tax bureau, if the city’s multi-family group is to be docked, the tax bureau is expected to invest hundreds of millions of dollars and it is difficult to meet the needs of small and medium-sized enterprises. . The block-based tax-enterprise direct connection platform can provide a unified connection platform for thousands of groups and small and medium-sized enterprises, and help the tax bureau to achieve the purpose of serving enterprises in a low-cost manner.

What are the benefits of blockchain electronic bills for users? With the electronic ticket of the blockchain, the entire claim has been reduced from the original half a month to a few minutes, and the time for consultation has been greatly shortened. This is a change that the blockchain brings to our lives. This is the first example. .

The second example is about “traceability.” Through the blockchain traceability, each product can be given a “digital ID card” that records the entire life cycle of the commodity from raw material production to logistics, warehouse receipts, and distribution. And this information is recorded on the blockchain, guaranteed to be tamper-proof, verifiable, and traceable. Throughout the life cycle, enterprises in different links and countries have endorsed together as blockchain nodes.

Users can scan the code to view the source digital ID card, and understand the information of the entire life cycle of the product, without worrying about the quality of the product. This year’s double 11, there are 400 million Tmall cross-border goods can be traced back through Alipay.

The third example, “About Finance,” how blockchain technology can help solve the problem of financing difficulties and financing for SMEs. We now have a lot of small and micro enterprises, the initial capital is only a few hundred dollars, but there are a lot of accounts receivable (because it undertakes a lot of projects), then how does it use the accounts receivable to make financing and loans? ? very difficult.

Our platform for accounts receivable created by blockchain exists to solve such problems. We call it “Double Chain (blockchain and supply chain)” with banks and cores.Heart companies, guarantee companies, small and micro enterprises.

The core company borrows from the bank, gives the project to the supplier, how to pass the accounts receivable, how the first-tier supplier passes to the secondary supplier, and all the links are clearly recorded in the blockchain. Based on this information, the bank is very confident to go to the loan, regardless of how much it can pledge the assets or the registered capital, because it can clearly see its entire link.

blockchain behind double eleven

Go back to the double eleven we just finished and see what role the blockchain has in the double eleven.

First, everyone is familiar with the buyer show and the seller show. It is that I bought the product and I didn’t match the picture on your website. So many people made a comparison between the buyer show and the seller show. The essence of this problem is the piracy, resulting in a wrong version of the goods.

How to solve this problem? This year’s double 11, ant blockchain through the Tmall on the line “鹊 chisel” system. The “seller” can be linked up by one click, quickly complete the copyright of the picture, and provide one-stop self-service for evidence verification and infringement forensics. Under the joint witness of the blockchain nodes of the judicial and notary institutions, it has become the ironclad proof of “cross-platform theft and rights protection”. We are also very pleased to see that through technological innovation, we can bring meticulous service to the merchants.

What should I do when I find the original stolen? We can log in to Alipay, search for the ant blockchain digital forensics applet, enter the evidence and infringement link after login, and then submit. A minute later, the case was uploaded to the Internet court, so you don’t have to go to the court to complete the lawsuit on the mobile phone.

In addition to the above examples, there are several other aspects of the double eleven also use blockchain technology.

1. Product traceability, 400 million Tmall cross-border goods enter the blockchainTraceability system.

2. Intellectual property protection, 5 million pictures are copyrighted on the blockchain system.

3. Digital identity, tens of thousands of merchants complete domestic and foreign cross-platform digital identity authentication through blockchain, and participate in global trade barrier-free.

4, 30,000 merchants complete financing through the blockchain-based supply chain finance ABS.

There are a lot of scenes mentioned above. These scenes are no longer in the concept layer today. They have been used on a large scale, and there are millions and hundreds of millions of traffic when the double eleven. The underlying technology that supports so many scenes needs to be solid. If it is not solid, the flow of the double eleven can’t be sustained.

About the platform of the ant blockchain, share a few numbers. The ant blockchain is our self-developed platform (linkage chain platform) and is enterprise-oriented, mainly based on financial scenarios.

First, size and performance.

I will not talk about TPS today. The complexity and environment configuration of different scenarios are very different. You don’t explain what the deal is, it doesn’t make sense. In all the scenarios we mentioned just now, there are processing as fast as a few nanoseconds, and there are contract processings as slow as hundreds of milliseconds. The transaction complexity range is very large. You don’t mention what the transaction is, saying that this performance is It doesn’t make sense at all.

We are talking about a more powerful number today – the scale of daily life is how many accounts are supported by the platform every day, and how many transactions are on the chain. The number shared for everyone is that we have a blockchain account system of 1 billion and a daily trading volume of 1 billion.

Second, privacy protection.

There are many privacy concepts in the previous concepts. We have increased the efficiency of communication between enterprises through the blockchain, but privacy is very important. It is impossible to make all the information publicly for efficiency, but The privacy of the blockchain is very difficult because others can verify it. It can be verified, invisible, distributed, not centralized, it is very difficult.

When we do it, not only can privacy be protected, but the ability, performance, and versatility of privacy protection must coexist, because the versatility of infrastructure is important, there are software and hardware. Software is like state encryption. We have 6 times performance acceleration in the industry. The hardware is chip-level. Based on such a black box, the transaction is executed inside, and the outside is ciphertext. So, every machine with this black box can be verified, but not visible to each other. In addition to using common hardware, we worked with Alibaba Cloud and Pingtou to develop a privacy computing hardware chip that belongs to our own blockchain. Of course, the cost of the blockchain, cross-chain, etc. are also important.

2020 focuses on cross-chain technology

Finally, others will ask me, it will end in 2019, and 2020 will come. In 2020, where is the technology and scene for the blockchain?

What I want to talk about is cross-chain. Most of the previous ones are single-chain, one source chain, one chain of supply chain finance, one chain of bills, etc. Each chain has its own business cooperation. Further up, we need to cross the chain. For example, if some assets in the double-chain chain have to be legally endorsed, there will be cross-chain cooperation. This technology and demand are coming soon.

At the Yunqi Conference in September this year, the ant blockchain also launched a cross-chain service, which has many challenges. In particular, the development language between heterogeneous chains is different, the logic is different, the privacy protection is different, the company agreement is different, how can they be well integrated to solve the trust problem, and some protocols that can translate each blockchain language and the underlying layer are needed. Trusted infrastructure, etc., which is already on the BaaS platform of the ant blockchain, you can use it, and different chains can be accessed through such services.

Finally, what I want to say is that the value network and enterprise network brought by the future blockchain are unquestionable. Any company in the world can transfer its assets and distribute it more efficiently. . At present, there are many challenges in the technology and industry of the blockchain. It is hoped that all partners will create together and make greater breakthroughs in the scene and technology.

Thank you all!
