About the Course

This second course of the Blockchain specialization will help you design, code, deploy and execute a smart contract – the computational element of the blockchain technology. Smart contracts allow for implementing user-defined operations of arbitrary complexity that are not possible through plain cryptocurrency protocols. They allow users to implement conditions, rules and policies of the domain applications. Smart contracts are a powerful feature that, when properly designed and coded, can result in autonomous, efficient and transparent systems. You will design and program smart contracts in Solidity language, test and deploy them in the Remix development environment, and invoke them from a simple web interface that Remix provides. This course features best practices for designing solutions with smart contracts using Solidity and Remix IDE. Main concepts are delivered through videos, demos and hands-on exercises....

Excellent course! Provided a good overview of how smart contracts adds a layer of value to the evolution in blockchain technology. The hands on programming experience was quite helpful as well.

Thank you; excellent starting point so I can have a good foundation to learn more Solidity programming; the discussion forum is helpful when I submit the code at the end of the project.

The course is easy if you have a basic knowledge in programming. It's outdated since it uses version 0.4.x of solidty and references an old Remix IDE. However if you change the compiler version you shouldn't have any problem following the course. I rate it 3 stars since it's pretty basic and the concepts are not explained in real depth. The quizes are not that great and the final assigment is almost trivial since it basically tells you what to complete. The optional docs are not that great and most of them point to the language documentation. The professor is obviously reading the script so her explanations don't feel natural. All in all, is a mediocre course.

This course helps us to gain basic knowledge in solidity, and makes a way for us to make ground works to gain more knowledge in solidity and developing smart contracts.The reason I am giving 3 stars is videos is short and tend to rush the topic, if you already have bit knowledge in smart contract and you came just for certificate it will be helpful for you, but for slow learns like me it is bit difficult for me.But still I would recommend you to take this course, because you get at least a knowledge about solidity and in future you can learn more

This course was "ok" in my opinion. Its really a shame that Coursera does not have quality checks running to ensure course material provided in their courses are up to date. Throughout the entire specialization, many links where non-functional since resources where not available anymore. Nonetheless, the course provides a solid foundation for learning more about blockchain technology, in my view.

It's an awesome course. The biggest problem I faced was that Solidity language as well as the Remix IDE keeps getting updates every now and then and the Course us using a much older version of them (comparatively).

It would be great it this course could be updated with the latest version so that it becomes easier for us to understand and be updated :)

The final project was very difficult to troubleshoot. When tests failed there is zero guidance or info on what unit tests were being run and what specifically failed. Solving this was like finding a needle in a haystack. Honestly, this method of learning is is not great as their is no explanation on what i did wrong.

Great work explaining and all but the only place i feel that could be done better is the code review part.The Instructor is just reading the code parts I feel it would be much more intresting to see live coding and designing the smart contracts with a jist of its idea at the begining.

It makes it very distracting to listen to the teachers pronunciations of the word "development", "events", amongst many others to the point I had to enable subtitles and read along while watching the lectures. The stress on the English language is completely off

Basic course on solidity. Week 3 is the important one. Two first weeks are very basic, learning basic datatype, structs and all that. If you know Java or any other programming language is not so usefull. Week 4 is best practices that are helpfull for future work
