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.

overall experience was not that good. should improve the teaching methods. The contents are precise but the method of teaching is boring

This is a very high-level overview of Blockchain. If you are interest in learning codes related to blockchain, you can skip this course.

only get to know about the theory, this course does not contain any content to get a knowledge of how to implement the block chain

Good for learning about the Blockchain basics, but were being constantly evaluated on things never thought.

hello i can't complete 1 assignment

The final activity could not be completed. The instructions were rubbish, the tool we were supposed to download and install didn t work and many many people had similar issues. I wrote to the discussion board about it and no one bothered to reply till the course ended and I ended up without being able to do the activity and submit the results, hence no certificate.

Really rubbish and a waste of money. Most the material was freely available on the internet anyway - as provided by links within the course.

If you are really interested in Blockchain, just browse the internet and find the free material available. You won t be able to get the certificate anyway here.

This wouldve been a great course but I had a few problems with it. Compared to other e learning courses I have taken, the text associated with each video IS NOT correct. This is most likely generated by AI and the audio of the video and given the lecturers accent....made it hard to follow along and take notes.

The final activity, did not work as expected and I saw far too many people having issues with this portion...thankfully got through it but this is making me reconsider completing the specialization due to how frustrating it was.

This course was completely out of date, and the instructor seemed like reading the text from the screen, and there was no explanation, I have experience in the field of Blockchain, and I would suggest that this course needs a lot of improvement, I was disappointed with the content

The professor is literally reading from a screen in front of her, without explaning a single letter or concept, just like a student loud reading a book in a classroom

too easy. You can read first several sentences on Wikipedia about Ethereum and Blockchain to find out all information in this course

the course offers a nice very general introduction, but I was expecting also an overview on technical aspects of the topic
