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

Since the instructor has a special accent it can be a bit complicated to fully understand the lesson for those whose language is not English, so I suggest activating subtitles to improve the understanding of the lesson.

Very thorough introduction. The final assignment, while not difficult per se, was arduous getting VM to behave. But I suppose those kind of configuration/OS challenges are very present in real-world implementations.

The course content was great but the final assignment became an issue because i have a new m1 mac that had a problem opening the VM. I didn't deduct points because there may have been something I did wrong.

This course gave me a lot of knowledge about BlockChain. Before this course, I didn't have any knowledge about BlockChain. I learned BitCoin and Ehereum. I knew, how they work, how to apply?
