Course Intro2:17
What to Expect from this Course1:09
I discuss various expectations from this course and also what this course is NOT about. Please have a look before continuing with the course.
Note: All the course resources including the glossary are in Lecture 30 titled "Bonus Lecture: Tools & Free Resources".

Understanding Software Systems2:19
In this lecture, I discuss various software systems and why you need to know them to understand blockchain.
Software Architecture Types1:57
In this lecture, I discuss the common software architecture approaches in order to understand blockchain technology going forward.
The Peer-to-Peer System2:55
In this lecture, let's understand the peer-to-peer or P2P system.
End Section 2 - Quiz

The Problem With Distributed Systems1:56
Define integrity as data accuracy and a system free of logical errors that performs its functions without corruption, and emphasize trust as a fundamental factor in distributed P2P systems.
Understanding Ownership3:36
Explore how blockchain technology enables secure ownership by recording transactions on immutable, distributed ledgers across multiple nodes, using cryptography for identification, authentication, and authorization.
The Double Spending Problem1:37
In this lecture, I discuss the Double Spending Problem and its relation to the blockchain.
End Section 3 - Quiz

Revisiting Blockchain Basics1:33
A brief recap of what we have learnt so far, to help you understand working of blockchain going forward.
Cryptography Basics6:31
Here I discuss basics of cryptography and its relation to the blockchain.
Knowledge Check
Intro to Hash Functions and Merkle Trees5:34
Explore cryptographic hash functions and Merkle trees, explaining how hash chains, leaves, and a Merkle root verify blockchain transaction integrity and immutability.
Visual Demo: Hash Functions1:53
Intro to Blocks2:35
Visual Demo: Blocks2:08
Explore how a block's hash with four leading zeros signals mining difficulty and data validity, and observe how data changes affect the block color and validity in a visual demo.
Forming the Blockchain1:26
Review how blocks are mined and linked by hashes, with the merkle root preserving data integrity, forming a distributed ledger technology on peer-to-peer networks with no central authority handling transactions.
Visual Demo: Let's Blockchain!3:48
Visual Demo: Distributed Blockchain2:23
This visual demo shows how a distributed blockchain keeps identical copies across many peers, detects data tampering by hash comparison, and highlights original versus altered chains for transparency and reliability.
Visual Demo: Tokens2:33
Visual Demo: Coinbase Transactions2:29
See how blockchain blocks record and verify transactions, trace provenance across blocks, and prevent double spending with digital signatures and asymmetric key cryptography.
Visual Demo: Signing Transactions6:27
End Section 5 - Quiz

Distributed Consensus11:01
In this lecture, I discuss Distributed Consensus in blockchain terms and why do we need it.
Types of Blockchain5:20
Here I discuss various types of blockchain in use today and how they compare with each other.
Understanding the Limitations6:18
Understanding limitations of any technology is as important as learning about its advantages. I discuss that here.
End Section 6 - Quiz

Blockchain Disruptive Use Cases & Applications10:23
Explore blockchain disruptive use cases across supply chain, energy, healthcare, real estate, identity, media, and decentralized cloud storage, with smart contracts and cross-border payments on Bitcoin and Ethereum.
Job Prospects in Blockchain3:35
Discover diverse career paths in blockchain, including front-end and back-end development, engineer, architect, and consultant roles, as demand grows, salaries rise in the US, and IBM and KPMG hire.
Course Recap1:18
Bonus Lecture: Tools & Free Resources0:22
Discover tools and free resources in this bonus lecture to deepen your knowledge of Fluxion and support your blockchain learning journey.

Requirements

No prior knowledge of blockchain or related technologies is required. This courses employs a non-technical approach to understanding blockchain technology
Basic knowledge of computer terminologies is preferred but not required

Description

Cutting straight to the point: Blockchain.

This course bridges the gap between:

various online content surrounding blockchain technology that is too technical
and
publications explaining specific applications of blockchain technology.

Understanding of basic concepts in blockchain technology is important in order to understand specific blockchain applications and its actual economic impact. This course aims to teach blockchain in a visual, compact and logical manner.

Important: This course is focussed more on blockchain as a technology and not so much on cryptocurrency. After completing this course you can expect to have a thorough working knowledge of blockchain technology along with various current, planned future blockchain applications and use cases. We will also discuss startups in the blockchain space, along with job prospects in blockchain.

What is covered in this course:

Blockchain foundations
Why do we need blockchain
How blockchain works
Visual demo of blockchain
Types of blockchain
Limitations of blockchain
Blockchain disruptive use cases
Job prospects in blockchain

Key blockchain concepts explained in this course:

Cryptographic Hash Functions
Cryptography
Merkle Trees
Double Spending Problem
Ownership
Distributed Systems
Mining
Peer-to-peer systems
Distributed Consensus
Byzantine Generals' Problem

We have also included a printable-PDF of:

Comprehensive blockchain terminology
FREE resources to explore blockchain further
Guide to securing job in the blockchain field and more

If you are ready to unravel the blockchain, let's get started!

Thank you and welcome to this course.

Best,
