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....

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

This course has a very good selection of content. There's some difficulty issues with the quizzes and final assignment due to they seem to be for a very begining audience instead of a technical skilled students.

It was a great course with a lot of great information. I knew a lot about blockchain networks before starting the course, but I still learned a lot.

There were several dead links throughout the course though.

Out of date: the content is from 2017 I believe, and this is a field that is evolving so fast. It was hard to follow along on the programming exercises, but it was a good introduction to the concepts.

The introduction to blockchain is pretty good. I had previous experience with crypto but the UTXO and stuff I didn't knew about it. Now i have a zoomed out picture of what happens behind the scenes.

Some of the course links don't work. The instruction for installation of virtual machine needs updating. I'm hoping the other courses in the specialisation go into more depth, as this is very basic.

Good way to begin with the blockchain technology ! Really interesting, still a bit frustrated that the web interface was doing all for us during the practical exercise on Ethereum blockchain

Information in the course was very good, but in the project part I have not felt like I am doing one POC kind of project, it is not at all interactive. It can be more practical if possible

Enjoyed it thoroughly. I'm not a Computer Science student but found the videos and materials very easy to understand. Thank you, Coursera, for providing such a course with this simplicity.

Good course for beginners. It gives you some hands on knowledge by exploring blockchains and helps you clear concepts. The course content needs some update to reflect current realities

It is really good course and the explanations are good, but a little more explanation in trickier topics will make it a lot better. Overall I have the basics of blockchain perfectly.

The format is good, but some of the content is already outdated. Would be nice to update it, fix the broken links, and add some newer information. Blockchain is evolving quickly.

Great course. Earlier I searched for lot of free contents on Youtube but couldn't find any effective courses. But here, it cleared all the basics of the concept. Really worth it.

Absolutely amazing optional resources. They give great insight to understand the topic, even on 2021. Broken links and lack of support were the only reasons not to give 5 stars.

Very good and enjoyable with lots of additional material allowing me to delve and investigate further. Still a little confused in some areas - but that's Blockchain I guess!

It could be better if the vocally delivered materials were organized in slides. However overall items were refered to within slides but they were not comprehensive enough.

It was good but i feel the video lectures can be more long and explanatory.I thought the video learning aspect would be much bigger than it was before taking this course.

The course videos are good. But some of the links given in the questions of the quiz are not working. The instructions for the final project could be better in my opinion.

If there were more conceptual questions in each of the quizes after each lecture then it would be very helpful in the learning process.

Anyways nice course, thank you

Good introduction to the subject. I would have appreciated more courseware content and less references to URLs. I'd suggest to make the slides available for downloads.

Teaching part is good and concise, however the final assignment is terribly instructed. Lots of details are also out dated and the team simply refuses to upkeep it.

It is a very nice course but some of the links are outdated which made it impossible to answer some questions in the graded section and learning section.(optional)
