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

Great class but I think the final project should be on a network, because it not user friendly to download a virtual machine and run all of this

A perfect introduction to the Blockchain topic. The optional reading material consists of even more in-depth materials and is a must-read.

Excellent course ! The only slight negative point I found is the English subtitling which, sometime, is not correct and creates confusions

The final project assignment took more time because of server problem and it does not generated account balance for too many times....

I was a little acquainted with the subject, the explanation were a little too summarized even for high level course. Anyway very good.

Interesting enough to get curiosity to go for Course 2.

A stepwise approach to get the concepts behind the generic name "blockchain"

Great. Informative. The lab was really good, although I'd prefer a more advanced CLI environment for learning the network concepts.

The final program part was not that well optimized. But apart from only that part everything else was pretty interesting to learn

The course is good but the project assignment was frustrating. The software used is of an old version. Need more explanation.

This course is all theoretical. If there were some implementation side by side, this course would have been more interesting.
