On May 28, the 2019 Global Blockchain Technology Development Forum (GBF), hosted by the 2019 China International Big Data Expo Organizing Committee, undertaken by the China Academy of Information and Communications Technology, and co-organized by Teleinfo and Odaily, was held in Guiyang.
Xiao Wei, director of Baidu Blockchain Lab, delivered a speech themed on "Baidu Blockchain Self-developed Technology and Commercial Implementation". In the speech, Xiao Wei introduced Baidu's blockchain business. Currently XuperChain single-chain can process 65,000 TPS per second, 20,000 TPS in the whole network, the network delay is less than 3 seconds for the public network, and the alliance network is less than 10 ms. It adopts a hot-swappable consensus mechanism, including DPOS, authorized consensus, PBFT, and smart contracts. Support Solidity and Go two languages.
He believes that the blockchain is not just a technology, and the industry is beginning to seek commercialization. At present, Baidu has launched six major products. In addition to XuperChain’s technical solutions, the other five industry solutions are: judicial solution XuperFair; intellectual property solution XuperIPR; data collaboration solution XuperData; edge computing solution XurperEdge; XuperEngine Baidu super chain open platform.

The following is the original text of the speech edited by Odaily:
Thank you everyone, here I would like to share with you a result of Baidu in the blockchain field over the past year.
Since 2017, the blockchain has become more than just a technology, but has begun to do some commercialization. The implementation of commercialization is actually a requirement for a company's technology, resources, and its ecological integration capabilities.
It is very necessary for a company to have core competitiveness.
During this process, Baidu integrated its technological advantages and resource advantages, and launched a Baidu blockchain solution - XuperChain. Xuper, with an "X" in front of it, is a variable, representing an infinite possibility, and it is also our hope that Baidu can use the blockchain to create a trustworthy society with infinite possibilities to connect.
Based on the entire Xuper brand, we Baidu has launched six products. The first is the Baidu super chain XuperChain, which has four sub-products: super alliance technology; multi-terminal, IOT technology; XuperCore public network technology; XuperCross cross-chain technology.
In addition to this technical solution, we have also launched five industry solutions: judicial solution XuperFair; intellectual property solution XuperIPR; data collaboration solution XuperData; edge computing solution XurperEdge; XuperEngine Baidu super chain open platform.
Next, we will briefly introduce the occasions where these six products are implemented.
At present, XuperChain single chain can process 65,000 TPS per second, 200,000 TPS in the whole network, the network delay is less than 3 seconds for the public network, and the alliance network is less than 10 ms. The consensus mechanism adopts a hot-swappable consensus mechanism: DPOS, authorized consensus, PBFT, smart contract Support Solidity and Go two languages.
It can support a variety of terminal devices, and it also supports many encryption algorithms. It can be safe and reliable, and solve the pressure of the entire blockchain network on storage and calculation.
Based on this project, we implemented two products. First, we have created an intelligent transportation for smart cities. Intelligent transportation is a process of road network coordination, with cameras, sensors, and law enforcement devices. The data is synchronized from each IOT node to the platform node, and recorded in multiple centers to ensure that the data is updated in time, tamper-proof and credible.
There is also a network of new energy micro-grids for smart cities. The concept of micro-grids is also very popular now. We may be the first in China to implement a microgrid.
Our work on the microgrid is divided into two steps. The first step is to cooperate with the lightweight nodes of charging piles. Taking the Internet of Vehicles as an example, IOT sensors, mobile devices, and in-vehicle devices become lightweight nodes through XuperLight technology, collecting trusted data to the blockchain network, realizing panoramic credible information collection, credible finance, and active decision-making operations through AI. dimension. We combine with new energy to realize the cycle of micro grid in a local area network.
The second solution is XuperData, which is an epoch-making product in the era of big data. Because it solves a core problem of the entire big data circulation - data availability and visibility.
They want to exchange data between two companies. At this time, you can only use the data if you give it to me. Based on this blockchain technology, you don’t need to give me the data. Even if I can’t see your data, I can directly Enable joint modeling using your data and features of your data. This also solves the problem of data circulation in the era of big data.
Based on XuperData, we have two landing sharing cases.
First, empower the government and create an open platform for the integrated management of government big data. When we go through the formalities in government departments, we don’t need to go to the Public Security Bureau or the Civil Affairs Bureau to issue certificates or notarize, because the data of government affairs can be opened up through the blockchain. , while not revealing some very specific information.
Second, this technical solution will be more suitable for the entire financial field, because finance has a large amount of risk control data, and the data between banks is a barrier. It is impossible for a bank to share its own data with another bank, because This is no longer an issue of core competitiveness, it is about data privacy and leakage.
Using XuperData, we can realize data sharing between multiple banks. Each bank has its own blacklist, and has its own portraits and standards for users. If these data are shared and used to control the risk of a user more accurately, it will generate a strong core competitiveness.
XuperEdge, a blockchain edge computing solution, uses blockchain edge computing solutions to integrate idle edge computing resources into more elastic computing power, bandwidth, and storage resources through blockchain technology capabilities. Machines have strong computing and processing capabilities. Through this solution, we can centralize these storage, computing, and bandwidth to provide external services.
In the XuperIPR blockchain intellectual property protection and transaction solution, we passed these evidences to the Internet court, including monitoring video infringement and so on. There are more than 100 million evidences that are legally protected on our platform, and we also provide some trading services for copyrights. This is the model that we copyright internally use within the platform.
These capabilities will be placed in the XuperEngine Baidu super chain open platform to provide services to everyone. You can directly use the service capabilities just introduced on this platform.
What I mainly bring to you today is that XuperChain is officially open source, and you can use all the things we just introduced for free without having to say hello to Baidu.
Baidu will continue to open source more commercialized industry solutions, and we will open source related technical solutions in the future. If you need to obtain more open source materials, you can pay attention to our public account, and there will be some information later. thank you all!
