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....

• Videos: not too bad, but clearly too short! The amount of videos could be at least doubled, with additional explanations, visuals, examples, etc. We call here "weeks" something that can easily be achieved in less than 1 hour. One Coursera certificate for a few hours of browsing the Internet? That's not PoW! Also, it feels I spent most of my time reading external resources.

• External content and reading: is always marked "optional", when it shouldn't. This is the only way to learn something and understand this course, and the answers to quizz questions can be in the external content. The links sometimes don't even match the order of the course. In addition to that, the time to read (10 min, 15 min) is often underestimated.

• Quizzes: are trivial. I could have finished the course by simply clicking "Next" all the time. Would it be complicated to add more questions (at least triple the number), and increase the relevance and level of difficulty? The time to complete (30 min) is overestimated (should be 30 seconds in some cases). The final assignment is relatively easy.

In short I would have expected more videos and original content, less readings (or only as further readings), decent quizzes.

I would strongly advice to follow the following course (in complement of the "Blockchain Basics" one): https://cartplus.top/learn/cryptocurrency.
