"What I love about the course's lectures is that by the end of each lecture I understood the concept presented clearly. Also, I like the opening of each lecture, it prepares the student, for me it lowered the fear factor when approaching a new concept in Bitcoin Network and Blockchain.

The course doesn't provide only the theoretical part of Bitcoin Network and Blockchain, George Levy provides many examples which delivers the objective of the lesson (lecture).

I truly recommend this course for new comers to Bitcoin Network and Blockchain.

Thank you George Levy for the great course."

Let's check what you have learned in this lesson with a few questions!
The Role of Bitcoin Miners
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

Demo: Hash Functions
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: Block Hashes
Now that you know about Cryptographic Hashfunctionsand learned what a SHA-256 Cryptographic Hash is, let's see how block hashing works and how hashes areused ina block that will be used in a blockchain.
Demo: How Block Hashes Work in a Blockchain
In this video demo, I describe how a blockchain gets built and how it preserves its integrity by using Cryptographic hashes.

Earlier, we definedthat "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 linkseach new blockto the previous block by using Hash Cryptography,and how changing a single block "breaks the chain."

  • There are no requirements needed to enroll beyond having a business interest in learning how blockchain and Bitcoin work.
