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

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.

Too little support from the mentors. Several participants, me included, couldn't finish the course due to technical limitations which were not offered to being solved.

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

Good basic course but unable to complete the final assessment because I am using a Mac with M1 chip. This is not mentioned until you reach the final assessment.

Seriously, dont waste your time with this course, there are other courses in Coursera much better. Better explained, better examples and much more detailed.

as a lot of others students I am very upset with the final test of week 4, I saw the discussions and too many people have my same opinion.

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

The instructor is talking too fast and withoiut enough visual aids for a complex topic like the blockchain.

Very very basic, providing no coding to do, and nothing that is going to help you remember anything.
