About the Course

This first course of the Blockchain specialization provides a broad overview of the essential concepts of blockchain technology – by initially exploring the Bitcoin protocol followed by the Ethereum protocol – to lay the foundation necessary for developing applications and programming. You will be equipped with the knowledge needed to create nodes on your personal Ethereum blockchain, create accounts, unlock accounts, mine, transact, transfer Ethers, and check balances. You will learn about the decentralized peer-to-peer network, an immutable distributed ledger and the trust model that defines a blockchain. This course enables you to explain basic components of a blockchain (transaction, block, block header, and the chain) its operations (verification, validation, and consensus model) underlying algorithms, and essentials of trust (hard fork and soft fork). Content includes the hashing and cryptography foundations indispensable to blockchain programming, which is the focus of two subsequent specialization courses, Smart Contracts and Decentralized Applications (Dapps). You will work on a virtual machine image, specifically created for this course, to build an Ethereum test chain and operate on the chain. This hands-on activity will help you understand the workings of a blockchain, its transactions, blocks and mining. Main concepts are delivered through videos, demos and hands-on exercises....

Very nicely arranged course and very informative. Learned a lot in no time. Only hurdle is The Ethereum Virtual machine takes hell lot of time in the Miner step. rest all fine. thanks a lot.

Out of date: the content is from 2017 I believe, and this is a field that is evolving so fast. It was hard to follow along on the programming exercises, but it was a good introduction to the concepts.

The instructor is talking too fast and withoiut enough visual aids for a complex topic like the blockchain.

Very very basic, providing no coding to do, and nothing that is going to help you remember anything.

Even if the idea is pretty interesting, the concepts are explained in a messy way.
