 Hello, everyone. I'm Peng Du, working for H3C as blockchain chief architect. I'm honored to have this opportunity to give an introduction about Hyperledger Chalo. And my colleague, Jiang Xu, project Chalo's maintainer will have a demo of Chalo V1. Chalo is a Hyperledger 2 project. Chalo's main target is to give a quick and easy way to deploy a blockchain network. It also provides quite a few maintaining functions, including monitoring, logging, health checking, and analyzing. It supports Docker, Kubernetes, and Ansible with a corresponding agent. And it provides the management of the life cycle blockchain. Chalo's architecture mainly contains three layers. The top layer is a dashboard, so the user can manage the blockchain easily with a website. API Engine is the core functions, including an agent engine and other maintenance functions. Different agents can handle different kinds of infrastructure, both Kubernetes and Ansible. Organizations can manage their own credentials and other resources. An organization can deploy their own channel or join others. And organizations can build their own consortium network or join an existing one. Chalo V1.0 focuses more on decentralized model. It has removed all resource sharing functions. Each organization can start up and manage their own nodes and fully control their own credentials. Here is Chalo V1.0's roadmap. We have finished the design of API Engine interface and Docker engine. And now we are working on a node starting up in API Engine and parts of dashboard. In Q3, we will finish the basic functions of API Engine and working with dashboard. And in Q4 this year, we will release Chalo V1.0. Here are some useful channels to contribute to Chalo. You can see the weekly meeting room Zoom link in wiki and all meeting minutes. Welcome to join us every Saturday morning at 9 o'clock Beijing time. Where are we now? You can try S3C branch based on 0.9 release. And here is Chalo V1.0 main branch. And Qiang will give a demo now. I'm Xu Qiang. I'm also working for S3C. Now let me give a simple demo. First, you need to stand for an organization and administrator account. Just like this. This organization also represents the organization for fabric. Then we can use the admin to log in. But don't forget your organization. Now we can see all resources for your organization. We need to create an agent for organization. We need to enter name, IP, and so on. But currently we only docker. In this part, we can see all the agent that we have created. Next, we can add the node to the organization. In the new version, we define the organization including the order node and the pure node. We can no longer separate pure from order. You can also still choose one kind of node. After adding the node, we can create a network. We need to fill a network name, type, and store. When you submit, then the order node or your organization will start on your own agent. Now we can see all the networks that have been created. In this part, we can see order nodes that we have created. This is all for my demo. Thank you for watching.
