Course content

4 sections • 27 lectures • 1h 16m total length

  • Centralised, Decentralised and Distributed Systems2:09

    Explore centralized, decentralized, and distributed systems, contrasting single-authority control with multi-node networks, peer-to-peer equality, blockchain use, and examples like Wikipedia, BitTorrent, and Bitcoin.

  • What is Blockchain?5:02

    Explore how blockchain removes the need for central authorities, creating a decentralized, distributed peer-to-peer ledger that enables transparency and immutability through majority validation while eliminating intermediaries.

  • Blockchain Basics
  • Evolution of Money6:21

    Trace the evolution of money from barter to gold coins, paper currency, checks, and e wallets, highlighting value, security, and centralization issues.

  • What is Bitcoin?6:18

    Explore Bitcoin as a digital, decentralized currency built on a blockchain, enabling trustless, peer-to-peer transactions without intermediaries, backed by cryptography and a finite 21 million supply.

  • Role of the Miners1:47

    Miners process and confirm transactions using powerful computers, solving cryptographic math problems to earn Bitcoin, capped at 21 million, while building the blockchain by adding blocks roughly every 10 minutes.

  • Role of the Miners
  • What is Cryptography?3:33

    discover how cryptography protects information over open networks by encrypting plain text into ciphertext with a key and decrypting to reveal the original message.

  • Hashing2:11

    Explore hashing in cryptography: a hash function converts any input into a fixed-length output, e.g., 256-bit hashes in Bitcoin, and is a one-way, irreversible function unlike encryption.

  • Block Hash - Demonstration3:25

    Explore how miners build blocks on the bitcoin blockchain by finding a nonce that yields a hash with four leading zeros, and how any block change alters the hash.

  • Block Hash on a Blockchain - Demonstration3:15

    Explore how blocks link via the previous block hash to form a secure, immutable block chain; mining with difficulty and thousands of nodes protect against 51 percent attacks.

  • Distributed Nodes - Demonstration1:29

    Explore how distributed blockchains maintain identical copies across network nodes, and see why tampering with a block breaks cryptographic hashes so the rest of the chain is rejected.

  • What is Consensus?1:26

    Explain why consensus matters in a distributed ledger by showing how nodes agree on adding blocks to the blockchain. It highlights consensus algorithms, including proof of work used in Bitcoin.

  • Proof of Work (PoW)1:57

    Explore how proof of work secures the Bitcoin blockchain as miners solve puzzles, validators verify, and rewards flow, while 51% attacks and energy concerns push proof of stake.

  • Bitcoin Controlled Supply & Halving2:36

    Explain how bitcoin's 21 million cap and halving every 210,000 blocks, reducing rewards from 50 to 25, 12.5, and 6.25, create a deflationary nature until 2140.

  • Bitcoin's Controlled Supply
  • What Sets the Price of Bitcoin?3:33

    Bitcoin prices vary by market due to supply and demand, creating differences between local exchanges and Google's USD price. Banking blockades and fiat crises boost demand, highlighting Bitcoin's deflationary appeal.

Requirements

  • No prior knowledge required, only the enthusiasm to learn!

Description

I'm pretty sure you have heard the term 'Bitcoin' everywhere, but haven't really had the chance to actually learn what it's all about.

In this course, I will teach you all you need to know about the fundamentals of Blockchain Technology and Bitcoin. We will see important concepts like:


  • How Money has evolved through time

  • What is Blockchain and Bitcoin?

  • Why do we even need Bitcoin?

  • Algorithms and mechanisms that allow cryptocurrencies to work

  • Applications of Blockchain

    We will also touch upon Ethereum and how it has introduced a variety of plausible applications as opposed to Bitcoin for payments traditionally.

If you always thought that bitcoin was the only use case of Blockchain, this course will provide you with a new perspective on how Blockchain will be able to bring about a change in several fields. This course will also provide you the foundation to gear your career in the ever-growing world of Web3, DeFi, NFTs, etc.

Regardless of what your background is, this course has no prerequisites and with an interest in learning, you should be able to grasp these concepts in no time at all.

The space is always rapidly evolving, and I will try my best to keep things up-to-date.

If you have any questions regarding the course, please feel free to reach out to me.

Note:

In this course, I do not discuss: Coding in solidity/smart contract development, altcoins (except ethereum), mining cryptocurrency, and how to purchase cryptocurrency.

Who this course is for:

  • Students of all ages, all disciplines.
  • Developers, Managers, and all sorts of business professionals.
  • Individuals who want to learn about the latest and upcoming technologies.
  • Those interested in trading digital assets.
