Course Description
Blockchain is the word on everyone’s lips these days.
Of course, blockchain is best known as the engine, or software, behind digital currency - otherwise known as cryptocurrency. Blockchain technology is used by millions of people daily for the use of payments, transfers and transactions.
But blockchain isn’t only about sending and receiving money! Far from it. It is important to understand about the use of blockchain as you will ultimately become the beneficiary of all its benefits, and if you were not aware of all those benefits, now is the time to start learning.
This online course will cover the basics of blockchain and cryptocurrencies:
Everything about what blockchain means, how was it created, why it matters, what it consists of, what makes it unique and useful, and why you should care. It also explains everything about cryptocurrencies, how they work, and why are they so volatile using some of the most popular ones in the market such as Bitcoin, Ethereum, Ripple and many others.
Furthermore, this course explores implications of different blockchains such as smart contracts, how they function, what are the advantages, and cryptography which makes them so secure.
After getting grounding on cryptocurrency and blockchain, the next time there is a conversation about these topics, you can actively participate in them. You should fully understand what cryptocurrencies and smart contracts are, the meaning of the words “miner” and “FIAT”, and you will not be dragged into scams.

It was but i would suggest having the course video description outlined, makes it easier for students to take notes.

Good basic introcution. However somewhat repetitive. The speed of videos seem a little monotone.

I little expensive but I am getting real value for my money. Wanted to get proper information about this bitcoin that everyone is talking about. That I did and then some.
By Dr Jesse Duran on 1/7/2021
I have checked out a couple of other courses as well that cover the topic but this one leaves no stone unturned. I probably need to go through it again due to the amount of information given but I feel very confident in the subject of blockchain already. Thank you!
