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....

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 articles included in the course are very informative but detailed explanation in lecture would have been fruitful. Lecture seems to be very concise without explanations where each and every statement is concept in itself.

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 content is out of date and some links even got a 404 error. Some instructions are not clear and/or updated. It would be better if the content stays inside the course as oposed to referring to many external links.

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.

informative; the assignment was a pain to setup. spent way more time on getting the setup to work than the actual exercise. i think it would be helpful to have those in the cloud and accessible to students.

Some of the information is outdated and I had a difficult time with the final test using a Mac M1. I had to use my old Mac Book Pro with the Intel chip and use VMware to run the Ethereum Environment.

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.

I wish things were explain in little more deep. I felt more like watching a power-point presentation than attending a to a course. Moreover, the videos could have been a bit more elaborative.

Provides a good high-level overview but a little too easy. The one programming assignment involved zero programming - just following instructions and clicking a bunch of buttons.

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.

El curso en sí es muy superficial y resumido. Es necesario ahondar dentro de los recursos "opcionales" que se ofrecen, para afianzar realmente el conocimiento que se requiere.

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.

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.
