À propos du cours

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.

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.

teaching and everything was perfect but the final project might not be feasible for everyone as downloading 2GB files is not easy

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

A good intro into the field of blockchain. The quizzes could ve been more challenging than just copy pasting some info from link,

interesting course but i wish that the course was more interactive and practical instead of just listening to the instructor.

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.
