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.

Blockchain Is indeed a very tough subject for a beginner. So the instructor shouldnt hurry up and instead just slow up.Some topics were very difficult to understand.

High level introduction - I was hoping for more meaningful exercises to drive the concepts home - as opposed to links to other peoples blogs for in depth analysis.

Last assignment was a lot of work and I learned quite little from it. The lecturer is to boring, you can make this much more exciting. The content is quite dry.

Course so far has been very weak. Very little material, and most learning comes from optional learnings (of which most are garbage), rather than the videos.

Instructor accent was quite thick and somemtimes incomprehensible. Final project instructions were "just okay." I had to use VMWare rather than VirtualBox.

I​t covers the basics, however, I wished the details in the optional sections are taught in in the videos instead of being links for extra readings.

a bit disappointed when i compare to other classes i took on coursera. I was expecting a more hands on approach with Jupyter based exercizes

Some topics went into details without a background and would more details for the assignment in terms of why we were doing each step.

It was very informative and understandable but the setup for the last assessment was hard, and so couldn't complete the course.

Many topics were under explained and need an update in the course. I had to read other materials to know the concept properly.

Too much distraction by moving backgrounds in the videos while presenting study material. The simpler, the better, IMHO.

Need lot of reading. I almost read number of blogs and websites. But my knowledge of the topic is also increased.

The teaching was good but their should be some examples to be said for regarding when the concept is explained.

Overall a pretty decent course. However, many of the links did not work so this course needs to be updated.

The content is okay, but the troubles with assignment (Problems with VM, Grading Upload) are a bit annoying

Not being a native English speaker, I found a bit of difficulty with the teacher's colorful pronunciation.

Although I could understand everthing, but video content is less in course, instead many links are given.

A fair number of the "further reading" resources provided no longer exist or redirect to irrelevant pages

Good for learning basic concept of blockchain. Some topics are too high level and not easy to understand.

Increase in video length and a little less reading material may help in making this course more helpful

The lectures could be lengthier. The course seems to be rushed. The programming assignment was good.

The miner part of the project is flawed. It crashes. Also the project instructions are incomplete.

more practical approach would have been better and programming assignment was not satisfactory
