About this Course

This course is designed to help you gain a comprehensive understanding of blockchain technology and its potential applications in different industries.

We'll start by introducing you to the basics of blockchain, including its definition and how it differs from traditional databases. We'll then delve into the role of intermediaries in the current system and how blockchain technology can eliminate the need for them. We'll also cover the concept of blockchain cryptography and its role in ensuring the security of transactions. Next, we'll explore the key components of blockchain technology, such as accounts, blocks, transactions, and Merkle trees. We'll also discuss the consensus mechanism and how it ensures that the network agrees on the state of the blockchain. We'll go over the two most popular consensus mechanisms - Proof of Work and Stake.

We'll then explain how blockchain transactions work and the different types of transactions available. We'll also take a closer look at the blockchain ecosystem and why industries need blockchain technology to revolutionize their operations. We'll discuss the challenges faced by industries when adopting blockchain technology and provide you with real-life examples of how blockchain is being used in different industries.

Throughout the course, we'll provide you with opportunities to apply what you've learned through practical exercises, case studies, and demonstrations. This will help you gain a better understanding of how blockchain technology can be applied in the real world.

Blockchain Cryptography

Cryptography holds a significant role in Blockchain. Hence, this module focuses on introducing you to cryptography with the help of a diagrammatic example. You will go through types of cryptography in which you will learn about hashing and Merkel trees.

Accounts, Blocks, Transactions and Merkle trees

To understand the function of a Blockchain, you must be familiar with its terminologies. This module enlightens you with the private keys, transactions, and blocks, where you will also go through the bitcoin example and the Merkel tree with a block.

Consensus Mechanism

Once a block is confirmed in a blockchain, a fundamental mechanism comes into the picture called the consensus mechanism. This module explains consensus with a popular example called the two generals problem.  

Proof of Work and Stake

Among the pile of proofs in Blockchain, Proof of Work and Proof of stake are the major ones. This module takes you through a thorough explanation of these two proofs. 

Mechanism of Blockchain Transaction

This module concludes all the terminologies learned so far, and you will get a better idea of the mechanism of Blockchain transactions and transaction distribution. 

Blockchain Ecosystem

This module explains the Blockchain ecosystem while you go through a Blockchain project. You will go through Blockchain projects like Bitcoin, Ethereum, Neo, and Hyperledger Fabric. Blockchain users, exchanges, verifiers/miners, developers, and applications are also discussed. 

Why Industries need Blockchain?
