If you've ever asked yourself where bitcoins come from and how they are placed into circulation, this video is for you. We will be discussing the concept of Bitcoin mining and a very special group of nodes on the network called "miners."

Bitcoin mining is how transactions are processed on the Bitcoin network, and how new blocks get added onto the Bitcoin blockchain.  It is also how new bitcoins are created and added into the system

The Role of Bitcoin Miners

Bitcoin is a type of Cryptocurrency.

Because of this, Bitcoin uses cryptography to control the creation of new units of bitcoin and to verify the transfer of bitcoins between parties.

In this video demo, I describe a SHA-256 hash function which is a type of cryptographic hash function that is used during the bitcoin mining process to sign, confirm and secure the blocks on the bitcoin blockchain.

I also include a link to the free, open source SHA-256 Hash generator I use in the video so you can go try it yourself!

Demo: Hash Functions

Now that you know about Cryptographic Hashi functions and learned what a SHA-256 Cryptographic Hash is, let's see how block hashing works and how hashes are used in a block that will be used in a blockchain.

Demo: Block Hashes

In this video demo, I describe how a Blockchain gets built and how it preserves its integrity by using Cryptographic hashes.

Earlier, we defined that "A Blockchain is a constantly growing ledger that keeps a permanent record of all the transactions that have taken place, in a secure, chronological and immutable way."

As you will see in this video, this chronological order and how Cryptography ties into the equation is what makes Blockchain such a powerful technology to keep Bitcoin secure.

Notice how a Blockchain links each new block to the previous block by using Hash Cryptography, and how changing a single block "breaks the chain."

Demo: How Block Hashes Work in a Blockchain

Time to see how much you understand the concept of cryptographic hashing.

There are four main components to Bitcoin which work together in order to enable Bitcoin to run.

We've covered them in different lectures of this course, now we tie them all together into one seamless flow.

Where did Bitcoin come from? How did it all start? Let's explore the birth of Bitcoin.

The Birth of Bitcoin

What makes Blockchain so valuable and why is it regarded as such a revolutionary innovation.

Preview 02:51

A bitcoin is a type of digital asset called a "Cryptocurreny." In this lesson we explore what cryptocurrencies are and some of the most popular types of cryptocurrency.

The Value of Blockchain: Cryptocurrency

As you continue to learn more about the value of Blockchain, it's important that you learn about what a digital tokens (also known as Blockchain tokens) are, and how they are used.

The Value of Blockchain: Digital Tokens

You may have heard the term "Smart Contracts" before. In this lesson we explore what they are, how they work and why they are so important.

The Value of Blockchain: Smart Contracts

Smart Contracts are a very hot topic in the context of Blockchain but the concept dates back well before Bitcoin was born. In this lesson, we take a look back at the birth of Smart Contracts and we talk about the "father" of the technology.

The Value of Blockchain: The Birth of Smart Contracts

Decentralized Autonomous Organizations (DAO) and Decentralized Autonomous Corporations (DAC) are a very exciting area in smart contracts and Blockchain technology. In this lesson we discuss what they are as well as why they are so important to know.

The Value of Blockchain: DAOs and DACs

Much is said about about the value and benefits of Blockchain, however it is important to note that there are also limitations to this technology.

In this lesson I cover some of the most evident and important limitations of Blockchain technology.

On August 1st, 2017 Bitcoin went through a "Hard Fork" which created a new cryptocurrency called "Bitcoin Cash."

In this lecture, I explain what Bitcoin Cash is and how it came to be, as well as how it relates to Bitcoin.

What is Bitcoin Cash?

In this video lesson I explain what Forks on a blockchain are, and I describe and compare the Hard Fork that created Bitcoin Cash with the Soft Fork used to activate Segregated Witness (SegWit).

I also explain Bitcoin Transactions, along with what SegWit is and how it works.

This is a very valuable lesson loaded with important information you should know!

On Forks and Segregated Witness (SegWit)

Only a limited number of Bitcoins will ever be available.... That means that at some point - there will not be any more bitcoins to mine. What will happen to the global network of miners?

On the future of Bitcoin mining

As you become more familiar with Bitcoin, there are several key dates in Bitcoin history which you should know about as they are very commonly discussed in various Bitcoin circles.
