Ethereum Tutorial: Ethereum & Smart Contracts from Scratch – Course Site

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.

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:

1. Build a smart contract language and an interpreter to execute code.
2. Next, create an ethereum-inspired blockchain, with its own mining implementation, and block structures.
3. Extend the blockchain with a network implementation.
4. Incorporate transactions and accounts. This will set up the Ethereum-like cryptocurrency, and create the concept of a decentralized computer.
5. 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. That way, the project is truly in your hands – ready to go as far as you want to take it.

Alright, let’s get started coding!
