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

The videos and quizzes were excellent and easy to understand, but the end course project was a whole different matter. There were so many unspecified conditions needed for the project and there weren't good instructions. It was very frustrating at the end.

Its a decent course which manages to teach you stuff that you don't know or do know to some extent but what it fails to do is that its a bit fast paced and not elaborate enough since the topics are a little complex to beginners

The course was good but the reason to give it 3 stars is that the programming assigment was a bit of complicated to install and no proper guidance was given to install it correctly. Videos could have been bit of simpler.

Tuve problemas con la ultima tarea dado que el programa que baje de los links dados por el curso no permitia correr el software ethereum.

Con lo anterior, no se dió una alternativa distinta para poder terminar el curso.

This course is too basic. Hardly goes over the concepts. The lady barely explains anything. I already knew most of the stuff so I know that others who don't know this stuff would still have no clue at the end of course.

The course is not organized logically so that it is not coherent and easy for learner to understand as a whole. The assignment is not well design to actually test learner's interpretation on the course knowledge.

The video lectures explained clearly but could have packed more information. The final assignment might need an overhaul since most people are finding it difficult to understand what is required.

The course was insightful. The project was quite time consuming and tediuos. PLease arrange an alternative project beacuse there were many people who coulnt complete because of the project

Every conent is worth.But the programming assignmnet need many resources and a good OS with 8GB RAMG(4GB recommended).So for people with 4GB need patience to complete the course.

Good introduction, a bit more strucutre could help. Over simple exams, especially the so called programming part. Hoping that more advanced skills will be measured later.

While the information was good some of the material given to read is outdated. Please update that.

Rest of course and delivery of content is very good and easier to grasp

This course covers the basics of Blockchain in organize manner. Reading resources are awesome although some material link was not correct, but overall nice experience.

Very high-level material and sometimes vague. The assignment didn't help to get more insight on the blockchain. Just had to run a VM and then a web based application.

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.

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.

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.

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.
