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.

Since there are multiple terms being used here lets clarify some so there is no confusion:

The data store that keeps all blockchain data is called a **ledger**. Each entry in the ledger is called a **transaction**. The transactions are timestamped and stored in groups of **blocks**.

On the ledger you can only add a new transaction or read the old ones. You can not update or delete anything.

The **ledger** is designed to be immutable using cryptographic algorithms (we will study in next chapter) and its distributed design. The **ledger** is replicated and maintained by multiple **hosts** or **peers** or **nodes**. This is why its called **DLT** or **Distributed Ledger Technology**.

In the next lesson, we will see a quick recap of the whole chapter.


In this lesson, we will explain the different terminologies used so far in this chapter
