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....

This is an introductory course to Blockchain. The supplemented material (in other words self-study) is excellent and in my opinion is the only way to master the concepts and details of this discipline

Il manque d'images, de vidéos et de croquis afin de comprendre visuellement le fonctionnement et s'en souvenir avec des images. Sinon bien expliqué et exercice

Very good introduction to blockchain. I am not giving it five stars because some links were broken to do the online test and had to find a workaround alone.

Presenter was good, but I prefer a presenters with a clearer voice(no accent) for this learning environment only, in a personal setting it would not matter.

Could also include some basic/fundementals of the code needed i.e., programming language etc., or at least trying to read some code in a penalty free mode

It was good overall. Some points to improve: Some links of the optional content were not working. I didn't find the Practitioners Perspective very useful.

As an introduction course to the blockchain, i think it's good enough. But, personally, Professor's accent made it difficult for me to follow the lessons.

Video is good. However it would be great if we can put subtitle inside video and have options for users to select what kind of subtitle they want to see.

It is really useful. I felt some terms were familiar to me and so it was easy to pick up, but for others I don't know if they would face any issues.

Great class but I think the final project should be on a network, because it not user friendly to download a virtual machine and run all of this

A perfect introduction to the Blockchain topic. The optional reading material consists of even more in-depth materials and is a must-read.
