Sobre o curso

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

I find this course helpful to absolute beginner and for one who wants to grasp the basic concepts of Blockchain . The tutor tried to explain most part with simplicity and good and sufficient details.

An easy course. The difficulty of getting to the point of starting the final assignment is an unpleasant shock, and a trial all by itself. The actual final assignment was a breeze. Allot the most time to getting the set up done, consult the forums for possible answers, and keep trying until something works.

Really a good course to take up for beginners. Concept explanation & understanding is pretty good. It really helped me a lot. Just a few suggestion to improve your manual for the final programming project regarding the setup. because i faced many issues but i'm good at debugging so i could get through it.

Excellent course for beginners , simple lessons made way more easier with a few minutes of video and quiz session helps to recollect everything . Had a few issues while doing last programming project but the people in discussion forum usually respond within an hour , which solved my problems...#must_try.

Excellent course! for beginners looking to understand Blockchain. However, there's one thing that caused few problems, that is, I have 4GB RAM but it stills took me a lot and lots of restarting my laptop to complete the final assignment, as my laptop hanged whenever I perform some of the steps.

This is a good enough for initial, but the learner have to depended on the outer source to get full understanding. But I must say great afforts are made in content of course, to make good understanding to learner, Course is overall good looking forward to take its course 2 from specification

Would have been convenient if summary points for each video were put in a single or two written slides along with existing speech.

And there are some practice quizzes with a single question which could be included in the video like Machine Learning course of Andrew Ng. has.

Buen curso como introducción a todo el mundillo de Blockchain. Tuve problemas haciendo el proyecto final ya que no son muy certeras las instrucciones para la descarga del programa principal, como recomendación sería hacer un video para cada uno de los sistemas operativos.

This course was truly enlightening to the shift that is the blockchain. I'm looking forward to courses 2-4. Some articles were dead links or removed by webpages owners beyond that error free learning to be patient with yourself and instructions for the last assignment.

Pretty good intro to blockchain, I have two comments: 1. please include more graphic illustration of the ethereum running principles instead of using long documents and hands on project 2. It would be better if there is a project env in Mac or directly under windows.

I agree that the course is good but I would have liked to see more contents in videos and more questions in quizzes which are well thought out. I am still not very much clear about a Block header and Merkle Tree. Would hit up the resources once more and ask in Forum.

Highly informative and helpful course on Blockchain. Concepts explained clearly and made easy to understand. Good quizzes at the end of each lesson. On hands experience to explore existing Ethereum and Bitcoin networks. Could have had more video material. Thank you.

The course was quite good, the last assignment was a bit challenging for a person not having an IT or Computers background, it took good efforts , first to understand the content and then to complete. Overall it was an exciting course and very good for beginners.

The course provides good introduction to blockchain technology. Some minor drawbacks might be: too "academic" style of presenting information; final project brings little value since it is all about launching virtual machine and clicking buttons inside web app.

Generally, I am not an online student kind, but I like this course. Well organized, the videos were quite explanatory and the test were challenging. It needs to update some broken links and I think a couple of test questions are wrong, but I recommend it 100%.

Course is nicely designed.Prof. has a good command over the subject and delivery of to the audience. Quiz can be sometimes tricky.

Assignment Environment creation was tough. Had to do a lot of digging on the net to find how to solve the VM issue. But worth it.

Great intro course for the basics on blockchain. There are lectures where concepts of Bitcoin and Ethereum are mixed- especially on merkle tree chapter. Specifying Bitcoin details, and then moving to Eth details then summarizing the common would be helpful.

The course is good, you'll learn a lot in fact. But I can tell you that the best thing about this course are the outside materials that it points to. Lots of good articles to read and cool videos to help you fully understand what you saw on video class.

It was very insightful for a beginner to start with. It covers all the cornerstones for the understanding of the blockchain system. I would have liked it if it had more practical assignments which would help us understand its use in the real world.

Liked the course and congrats to all in the Project instructions need one update. The answers are there in forum to run the VM in detached mode. If than can be mentioned in the instructions pdf it will be helpful. Thank you for the course.

Great course with great compilations of good resources. Optional readings are a must if you want to deepen your understanding. I dropped one star because the transcripts of this course are horrific. Otherwise, it is a good course

por Sven A

The course filled its purpose: I learned the basics. But I won't give 5 stars because I wasn't able to comprehend what was the home assingment about and I do not still have general view how the blockchain works as a technology.

It needs an assistant to reply to student's questions and errors. Remix IDE is not what it used to be at the time of recording this course. Needs course update very badly. The concepts and resources are still very pertinent.
