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....

It could be better if the vocally delivered materials were organized in slides. However overall items were refered to within slides but they were not comprehensive enough.

It was good but i feel the video lectures can be more long and explanatory.I thought the video learning aspect would be much bigger than it was before taking this course.

The course videos are good. But some of the links given in the questions of the quiz are not working. The instructions for the final project could be better in my opinion.

If there were more conceptual questions in each of the quizes after each lecture then it would be very helpful in the learning process.

Anyways nice course, thank you

Good introduction to the subject. I would have appreciated more courseware content and less references to URLs. I'd suggest to make the slides available for downloads.

Teaching part is good and concise, however the final assignment is terribly instructed. Lots of details are also out dated and the team simply refuses to upkeep it.

It is a very nice course but some of the links are outdated which made it impossible to answer some questions in the graded section and learning section.(optional)

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.
