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.

For me, an experienced developer, the course was quite easy but still useful. The topics were good introductions to the serious reading outside the course. The course gives structure to the readings which helped; I've had to struggle through learning languages from the specs in the past and it's not easy. The final project was annoying; it required the use of "not best practices" as the automated grader is looking for specific keywords. Also, Solidity is up to version 0.8.25 and the Remix user interface bears little resemblance to what we see in the course. The course needs a serious facelift. It would be good to preface this course and the next course with an overview of how smart contracts and Web3 Dapps interact. As I've worked through this, it's becoming clearer that a lot of the code that I would normally expect to see in Smart Contracts isn't going to be there. Primarily, Smart Contracts should only return values that reflect the status of the executing transaction (e.g. Solidity 0.8.25 on Remix does not support returning strings or arrays); any data that a user interface might use should be logged via "events" (now that I know that Web Dapps have a "watch" handler that can look for events). Thus, Smart Contracts exist to primarily write to or modify the blockchain, while Dapps read from it.

One of the best course i found here in coursera. the only thing i didn't give 5 stars is cause of the final exam: i think it's a little tricky to understand what's wrong with the code if there's no direct feedback on where the error is, the automatic-evaluator kept saying that something is wrong but not where!The course still is really good, good explanations, a lot of resources and plenty of complementary websites, videos, sources that helped to understand the course. thank you so much, i'll begin the next course soon!

This course was particularly important because it deals in good detail with the inner workings of smart contracts and its programing language. What I found disrupting is that the Remix IDE shown in the videos won't match what i saw in my browser, making hard to follow the instructions. For example, I coudn't find the details button one of the quizzes ask to click. Those two question were wrong because of that. (I wasn't able to see the transaction details)
