In this course, we will build blockchain concepts from the ground up. We will start with basic cryptography constructs, like hash functions and PKI encryption, to first build a solid base for understanding blockchain and appreciate its value. Then, we will explore the Hyperledger Fabric technology by IBM using hands-on development environment within your browser. This course is a great starting point for engineers looking to develop expertise in blockchain technology with Hyperledger Fabric specialty. In this course, you will deploy your own blockchain network, deploy chaincode on it and create an application that invokes your chaincode running in fabric network. You will also learn to manage fabric user identities in your application using wallets.

# Wallets and Identities in Client Application

Now lets see how the wallet and user identities work.

We can issue a new user's key and get CA signed cert by contacting the CA. Here are the needed steps:
1. A valid existing user A `registers` a new user X to CA. The CA returns the `enrollment key`.
2. The user A shares that `enrollment key` with X
3. User X/A contacts the CA to `enroll` user X and passes in the `enrollment key`. CA returns valid key and signed certificate for user X.


In this lesson, we will see how wallets and identities are used in client applications through a sequence diagram.
