Ethereum Tutorial
Ethereum & Smart Contracts from Scratch
The most requested topic for a course I've had so far is to "build a smart contract blockchain and cryptocurrency." And for plenty of reasons:
Smart contracts are the main feature behind Ethereum, which is the second most valuable cryptocurrency.
Learning smart contracts is a natural next step after learning about blockchains. A blockchain is a decentralized ledger. A smart contract blockchain is a decentralized computer.
A smart contract blockchain can support decentralized applications. This opens the door to a wide variety of solutions.
Based on these points and more it would definitely be a valuable learning experience to try building a smart contract blockchain and cryptocurrency like Ethereum.
So it can be quite surprising to discover that existing tutorials are challenging to find. Sure, there's the Ethereum documentation. But this information is better understood when you're pretty knowledgeable about blockchains already. Likewise, other resources you find, like articles and videos, mostly focus on aspects of a completed Ethereum system. They don't take you through the process of completely building a smart contract blockchain and cryptocurrency.
However, it's understandable. A complete system like Ethereum is quite complex. It uses many advanced data structures and technologies. And untangling the interaction between its many components can feel like navigating through a labyrinth.
This is why I made it my mission to create a "Build Ethereum From Scratch" tutorial that focuses on the essential elements. By the end of the tutorial, you should be able to execute smart contracts in a decentralized way.
And with a few months of work, here you have the finished product. Here is the course journey:
Build a smart contract language and an interpreter to execute code.
Next, create an ethereum-inspired blockchain, with its own mining implementation, and block structures.
Extend the blockchain with a network implementation.
Incorporate transactions and accounts. This will set up the Ethereum-like cryptocurrency, and create the concept of a decentralized computer.
Come full circle by running smart contracts on the blockchain.
By the end of the course, you will have built a decentralized computer platform that resembles many of the key features of Ethereum. In addition, at the end of the course, I'll provide a list that you can use for continued development. That way, the project is truly in your hands - ready to go as far as you want to take it.
Take this course if you want to learn how Ethereum works. Especially take this course if you've been hoping to build your own version of Ethereum. By the end, you'll have a unique item on your resume, or even the foundation for your next startup.
Alright, let's get started coding.

cryptocurrency | full-stack edition
Then an excellent intro to the blockchain is "Build a Blockchain & Cryptocurrency | Full-Stack Edition" and finally this as a final course.
es6 - a fun
This course is very advanced, so I would recommend if you don't know javascript to start with his course "Essentials in JavaScript ES6 - A Fun and Clear Introduction".
enjoyed every single milestone
I followed along in my own environment, and enjoyed every single milestone achieved along the way.
some really interesting parts
I find myself saying, "So that's how X works in Y framework..." In short, even if you are not interested in blockchain, I would recommend this course as a deep dive into some really interesting parts of programming.
by using proper terms
David does a good job of narrating his coding by using proper terms for coding.
explaining each topic clearly
The instructor did a commendable job in explaining each topic clearly and answering all my questions and doubts in QnA section.
entire ethereum beige paper
It appears that the entire Ethereum beige paper is covered.
blockchain & cryptocurrency
also took another
Before taking this course I also took another course from the same instructor,"Building blockchain and cryptocurrency", and I can say that this one is much in-depth and exciting than the prior.
computer science coming
That's just an incredible amount of computer science coming at you at lightning speed.
find myself saying
flow.without visual representation
Reason for giving me average rating in spite of my appreciation for the course instructor for picking this unique topic is due to the fact ,that the code flow got hard to understand from "Accounts and Transactions" sections onwards.I would have appreciated if you have used diagrams and flowchart to make us understand the code flow.Without visual representation of the code,it got reallly tough to undertand About 25% through the course.
