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....

The. study material is good, but that's about it. Several links in in the course and quizzes are dead. The final assignment is a nightmare to set up and run (I'm using a 2.6GHz i7,16GB macOS), but is a piece of cake to actually get graded. I think if as an alternate to setting up the whole VM etc we could also get the code repo to actually run and tinker with on our own, I'd give it another 2 stars.

Although I respect the lecturer and the effort they have made to make this a useful course but compared to many other courses on Coursera, I don't think this is a good course. The teaching material is not well-organized. The teaching method is not smooth and fluent. The accent of speeches is a bit Indian and the speaking intonations are awful. It's like she is reading from a PowerPoint presentation.

all this "Module Objective" and "summary" on each session is very old fashioned, specially as many of the goals are "Be able to discuss...". while next to the goal follows just elaboration of some specs...

I think the course is ok if you want a glimpse about the field and get familiar with the technical vocabulary, but for really learning I would advice looking elsewhere.

While video lessons were helpful, assignments/quizzes were pretty bland and final assignment did not function properly so was unable to submit. A bit misleading on assignment/quiz time - 4 multiple choice questions shouldn't be listed as 30 minutes of work. Overall, it's an ok starter course but needs some work.

Some of the terminologies used in the video are directly used without prior explanation which makes it really difficult to understand. I had to frequently visit the web to understand the technical terminologies that were used directly. Anyways, the resources attached with the course are awesome.

certains passage sont top, et ensuite ils nous renvoient vers des sites pour faire de la lecture... si c'est pour faire de la lecture je n'ai pas besoin de cela, je peux aller seul m'instruire.

je m'attendais plus à une vrai formation, quelqu'un qui explique les choses etc...

The video lectures in this course are too short and laconic. Most of the things are provided as reading material of other blogs and articles already available. There is barely any point of doing this course. Just read online articles and you'll know everything in this course!!

I'm sorry, but I need to be honest. The course does not meet my expectations. The subject is complex and the course does not provide a clear and easy intro to the subject. I was able to finish it because I had some previous knowledge on the subject.

More than half of the reading links are dead, the assignment is throwing an error that many people are getting and nobody seems to be answering the forum. It's a dead course imo, I regret starting it, I should've searched for a newer one

The quizzes are somewhat weak, and some questions have weird wording. Overall, it's an okay intro I guess. I didn't like the corpro-training style videos and staging backgrounds.

This is a very high-level overview of Blockchain. If you are interest in learning codes related to blockchain, you can skip this course.

only get to know about the theory, this course does not contain any content to get a knowledge of how to implement the block chain
