Building Blockchain-based decentralized applications using Ethereum

Course description

In this 3-day course, you will learn the fundamentals of Blockchain and how it works.

One of the hottest technologies of late is no doubt Blockchain. But what is a blockchain? A blockchain is a digital transaction of records that are arranged in chunks of data called  blocks. These blocks then link with one another through a cryptographic validation known as a hashing function. Linked together, these blocks form an unbroken chain— a blockchain. A blockchain is programmed to record not just financial transactions but virtually everything of value.

In this course, you will learn the fundamentals of Blockchain and how it works. Once you have a good foundation in how blockchain works, you will use a specific implementation – the Ethereum network. The Ethereum network supports an execution environment known as Smart Contracts, where developers can use them to store digital currencies or assets on the blockchain. You will see some real-life use of Smart Contracts, as well as learn how to create tokens (such as NFTs), something that is getting a lot of investors’ attention lately. At the end of this workshop, you will be on your way to your first ICO.
