The Blockchain is digital “Runestone”. We choose to verify over trust. Some of its properties are:
- Provenance
- Consensus
- Security
- Immutability
- High availability
- Finality

This was a great introduction course on Blockchain and Cryptocurrency. I truly have a greater understanding on this subject. I am curious to see what the end game is for many who attend this academy. I for one am looking to begin a career in this industry, as I see it having a major impact in the coming decades. I am nervous as I do not have a back round in Tech and feel this would be a difficult industry to enter into with out the proper training. Does anyone have any advice on what steps I should take? Thank you in advance and good luck everyone!

Hey hello Everyone, nice to see everyone here so engaging and discussing. I have a question here, I am a total newbie to this world but I do believe that tech is the future so that is why I have joined this place.
So I did blockchain course until this topic (Blockchain & Cryptocurrencies - discussion) and one question that never leaves my mind is that how does bitcoin or any other crypto is created, like I do understand how money in real-world works, but l still can not get my head around how is Bitcoin or any currency became a valuable unit to use for financial transactions?
Cause from my knowledge that I have at this moment and time crypto is an app that does something or is responsible for something and that adds value but how it becomes currency? So that is why I am curious to understand this. If someone could explain me like a human to human I would appreciate it. Cause at the moment I am in a state that I would name as curiously confused and I really want to understand it. Thank you very much for your help
Bitcoin is a protocol that enables digital scarcity. There will only ever be 21M Bitcoins in circulation. This is hardcoded in the source code. Bitcoins are created as a block reward for miners that successfully find a new block. The block reward is also halved every 4 years and eventually it will drop to 0 at that point no new Bitcoins will be created.

Hey Tomche! Maybe take a look at Robert Kiosaki’s book “Fake”. Fake money, fake teachers, fake assets. Could very well clear some things up. It isn’t about Cryptocurrency, but it definitely makes a hard case for why it is needed.

Great, thank you for your advice, Information is what I need 
Wow, really like the look of that, never heard of Thortspace before so going to take a look and see if i can use it - great there is a free version as well. Thanks for sharing!
If you had a blockchain running on traditional computing, do you believe it would be possible to hack the block chain using the power of a quantum computer? This isn’t something that is necessarily relevant now, but in the future it might be.

Really enjoying this course and the whole Blockchain technology field! I had jumped on the JavaScript first but decided to take a break and learn the basics first.
Very exciting! I believe I am on the right path. Well, I don’t believe, I know it!
Thanks Ivan!

It holds the value that people give to it. It is dependable on the size of the network. The more people use it, the more value it holds.
I read this yesterday and wrote on my notebook, but not sure where I got it from. You can just google if you want to find it:
"Cryptocurrencies are only valuable because of a shared agreement that they are valuable. Their value is a product of digital handshakes over millions of transactions firming up that consensus."
"Like any currency, cryptocurrencies gain their value based on the scale of community involvement (like the user demand, scarcity or coin’s utility)."
Things like the dollar losing trust and value due to inflation as an example motivate people to buy more crypto. And not to mention that blockchain is the infrastructure of the future.
There’s something called Metcalfe’s law that states that:
“The effect[ clarification needed ] of a telecommunications network is proportional to the square of the number of connected users of the system ( n 2). First formulated in this form by George Gilder in 1993,[1] and attributed to Robert Metcalfe in regard to Ethernet, Metcalfe’s law was originally presented, c. 1980, not in terms of users, but rather of “compatible communicating devices” (e.g., fax machines, telephones).[2] Only later with the globalization of the Internet did this law carry over to users and networks as its original intent was to describe Ethernet purchases and connections.[3]”
(That is for telecommunications, but the same applies to cryptocurrency.)
Hope that helps!

My mind is blown away with the Blockchain and all the information I have learned, that’s what most people fail to understand is the technology behind Bitcoin. Love this course! so glad I came across you Ivan

@Alko89 I like this explanation! Thank you
What happens when the block rewards drop to 0? What would be the new incentive for miners in this instance?
No one knows for sure, the idea is that by that time miners will be able to get compensated by fees because Bitcoin will be so valuable.

Hi Ivan and all the great minds on this academy !
I’m a newbie on here with no prior knowledge or experience. However , I have really been enjoying every bit of my learning experience so far. I love the way complex concepts are simplified and made easy to learn. I have learnt so much in just a very short space of time and I am so happy I didn’t hesitate to join the academy. The series of homework and assignments help me understand each section deeply rather than just memorizing stuffs. The only thing is that I have not been writing notes but I have understood everything so far. But, I need advice if I should continue without writing notes or start writing notes. Thanks !
