Course Description

Caution: Each Student will need to purchase The Project which is not belongs to this Course. I have used paid Project on this Course.

I have Copy+Pasted the code from the paid Project.

How to create your Own Cryptocurrency. This is the complete Cryptocurrency making Course based on blockchain technology using C#..

 Here, What You will Learn:

 > How Miner’s can join the Network

 > How Proof Of Work function Works by solving Cryptographic puzzle based on Sha256 algorithm

 > How real-time transactions is added to the mempool

 > How Mining Works and Generates New Coins

 > How Transactions are added in a Block after Mining

And:

 > How new block is added in BlockChain after adding transactions in a Block

 > How System resolve the conflicts from a longest chain by validating each block along with verifying each transactions

 [ Consencus: “How Longest chain Win”  ]

 > How Signature of a Transaction get verified

 By using public key

 > How public and private keys get generated using RSA algorithm

 > How Client User generates Signature using Private key

And:

 > How Wallet Transaction Works

 > How "Blockchain Client" for users to generate wallets and send coins

 > How to Buy digital content from Online Shopping Site using this cryptocurrency

 > How user can check Life-time Transaction and balance

 > How user can send coin to another user using mobile wallet after scanning QR Code

 > How user can generate QR Code image to send/receive coins

 And many more….

Why Cryptocurrency is the Future?

 All you need is to generate public and private keys then save it in order to make transaction.

 [No Need Bank to follow complex process]

 Anyone can receive money using their publicKey only.

 And anyone can send money using wallet app to generate signature using privateKey.

 This is the most easiest way to transfer money within seconds. In near future the process will be so efficient that user will able to make transaction using human body parts [Artificial Intelligance]

Initial Story:  

Anyone who will download the script can join the network by broadcasting the network and they are recognized as Miner. At genesis(initial) 1st block, only miner will have few coins. So, 1st miner will give coins to new user . Thus transactions will take place and then Miner will mine the transactions and system will give few coins to miner as reward. This way new coins get generated. Whole information is saved in miner’s machine.

 You will understand whole process once I will explain blockchain theory and You will better understand once you finish building Cryptocurrency application with me.

How this Coin will Get Real Values

 If Miners confident with this script and start joining the network and if so many users do transaction with real fiat currency that time this cryptocurreny will have real values. It’s totally based on trust and faith..

 And coin values also follows demand and supply rules of economic…

I appreciate the structure of this course, which effectively separates theoretical explanations from practical applications. This approach enhances the learning experience by allowing learners to grasp concepts and see their real-world applications. I find this course valuable not only for developers but for a broader audience as well. As an auditor, understanding blockchain technology is essential for evaluating and auditing blockchain-based systems. This course provides crucial insights that can benefit professionals in various fields looking to deepen their understanding of blockchain and its implications. Thank you for creating such a comprehensive and engaging course!..

Toufiq is great in explaining investment concepts to people who are starting their journey. I have been investing in crypto for a couple of years before taking this course and I have to say that this course opened my eyes for new opportunities to do better investing strategies.

By Andriy Belizky on 6/29/2021

Excellent level of detail and explanation. I love the fact that its all practical and hands-on. C# is my favourite language and it is extremely useful to see blockchain implementation. thank You so much for this incredible content. You are a star

By Kas Pintxuki on 1/28/2021

Until now the Instructor has not written a single line of code, only copy and paste the functions, the teaching method is basically that, copy, paste and right click to import a class, it does not explain what it is for at all, do not lose your time.

By Jeremiah Isaacson on 1/9/2021

Just a bit unclear. I get you say it will be clear later on but still I'm confused right now.

By Travis Myvett on 10/29/2019

Toufiq is a brilliant developer who really set a big goal for himself when designing this course. I liked that we are able to see and feel him struggle through errors and crashes to finally get to the prize! What Toufiq passes on to the students of this course in 10.5 hrs would have taken months to figure out and researh! Thank you for your hard work and sharing the fruits of your long hours of building and testing Toufiq.

Great lectures and in depth tutorials covering pretty much everything to do with the blockchain and how to understand it, work with it and implement it! Fantastic, can't wait to implement the intuition concepts and code tutorials in real time. The course structure, presentation, information on current leading platforms, coins etc is top notch and looking to see more courses like this, see you till next time. Thank You for a wonderful Blockchain Ride and special thanks to Toufiq... I have got a real good overview about blockchain. The author shared the content the way one does the scripting and the other one explains the subjects and backgrounds. As novice-programmer the scripting parts have challenged me however I have been able at any time to follow and realize the script. I used the advantage of this type of course to pause and repeat lectures. All together a great course, well structured and a good start into blockchain with fundamental knowledge that lets you look like a pro.. I will definitely hire you..!

The course is really useful. the instructor has taken lots of efforts to teach the concepts. and I think this is the only course till now related to this topic.. instructor also helps a lot. when you are having any doubts. Thank you, sir...

By Pavel Meshcheryakov on 12/4/2018

Это хороший курс, использующий современные технологиии, такие как ASP .Net Core. Этот курс позволяет понять, как устроены криптовалюты, а также, как подобные задачи можно решать с помощью веб-интерфейсов

By Mor Cohen on 9/18/2018

Very poor. There are no explanations. Throughout the course there is a copy and paste of the prepared code without explanations. The author did not speak English comprehensively. Very expensive and not worth the money !!!
