课程概述

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....

Really l​earned a lot about the fundamentals of blockchain, being a software engineer looking into blockchain. It just got me up to speed with the underlying workflow of blockchain and more. loved it.

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

It is a great and awesome course for total beginners, no prerequisite required, video lectures are short and crisp, moreover, the reading material attached is worth reading for a deep understanding of the core concepts. Anyone can easily complete the full course within 2-4 days.

As an introductory level course, it was a good jumpstart into the technology. But I think it could dive further into the details of real world use cases. Otherwise, it is perfect for a beginner like myself.

Everything in the course was as simple as crisp as possible. Except for the assignment!!

This is awful. In the final project, the miner never generated ether. Therefore, flunked. I understand it perfectly. I couldn't get the ethereum application to run correctly. I posted this issue to the forum and read other posts, followed the troubleshooting tips and still doesn't work. THERE IS NO WAY TO GET TECHNICAL SUPPORT FOR THIS CLASS OR EVEN TALK TO A HUMAN BEING. if you aren't going to have contact information for technical issues, you are setting some students (like me) up to fail. That is shameful.

limited to no support form the TA. The end assignment requirement was a high end computer which wasn't specified before. waste of effort.

The final project was not properly structured.

The content was good, but the links for supplemental content need to be reviewed and updated- a few are not available anymore. Also, the final project is buggy. The first account on each node would not activate, and the ethereum was added to the first account on the first node, so I was unable to send a transaction. That's why I got 90% on the final- it didn't work.

It's a very good basics course for the beginners and enthusiasts to move ahead in their career towards the Blockchain specialization

As expected. Basics covered. Final assignment requires a VM which in some cases causes issues. Overall, a useful course.

Beginne friendly and highly informative. Many links were broken/not working, they need to be modified or removed.

This course was "ok" in my opinion. Its really a shame that Coursera does not have quality checks running to ensure course material provided in their courses are up to date. Throughout the entire specialization, many links where non-functional since resources where not available anymore. Nonetheless, the course provides a solid foundation for learning more about blockchain technology, in my view.

There is decent content but some of the important stuff is dated like the computer requirements. Reality is you need a computer with much more resources then what is currently listed under 'Course Info' tab, it is also not trivial to setup the environment and there is no one to assist you, not the instructor nor the assistants because there aren't any. In addition, If you have an M1 or M2 Mac you will not be able to complete any of the projects because the project material and computer setup excludes these machines. This in turn means you will not be able to complete the certification that goes along with this course and the other 3 courses in the series. Do not subscribe if you have to pay if you have an M1 or M2 its not supported, this is not listed in the computer requirements.

Since the instructor does not reply in the forums and there aren't any assistants that do that I am aware of many students question's go unanswered, there is no one administering this course its self study, you need a computer with x86 architecture that can create virtual machine with 8gb of Ram ideally. Anyways there are more modern ways of setting up an environment for Ethereum, virtual machine on a home computer should be the last thing in my opinion. I had to unenroll because the project is impossible with Macs with Arm architecture.

Should make more use of better visuals.

Videos are way too short and basically reading a reference text. Not sure what the benefit of taking this course is compared to buying an audiobook on the subject

Extremely dry for something that was actually created on very practical basis.

Hopefully it will improve in next courses

Pros: This course does cover blockchain basics, and provides an okay structure for exploring the space.

Cons: The course content (lectures, quizzes, and assignments) are uninspired and rote - the professor doesn't understand how to educate. Far below the quality I expect from Coursera.

Question in stile `select the wrong ending for sentence` are super confusing and not widely used anymore in nowadays e-learning anymore.
