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)

I think the assignments could have less template code in it and there should be a more quality driven way of evaluating the code. I agree the former is not really the intention of the course and the latter is time consuming. But the course would feel more comprehensive and practice driven with these two changes. Maybe alumni could be roped in as mentors or TAs to do the grading ?

This class is very good. The lectures and class material are good. I can't give it a full 5 stars because it needs to be updated to 2020. I know that Solidity and the world of blockchain is always changing, but if Coursera doesn't keep up with changes it will become obsolete and no longer a viable option for advanced education.

Informative course. You MUST have some knowledge of coding Solidity or it may be a struggle (not a knock against the course itself).

Would be 5 stars, but the course is slightly out of date. With a subject that, by the course's own admission, is constantly changing, the resources shouldn't be from 3 years ago.

Coverage was good, just one thing I would suggest to improvise if possible is the ballot program which was used as the sample for coding would be great if explain coding at hand like a live implementation will give a much better idea of the happenings. Still the content was very comprehensive overall !

Overall the course is great. The instructions for the final project are a little difficult to understand with at least one incomplete sentence that left me at a loss as to what it meant. Otherwise, good course and I know more about Blockchain and Smart Contracts than I did at the start.

Informational, but you really have to dive into the optional resources to learn. Final projects guides you through the steps a little too much. I feel like I have learned a lot but left to myself I wouldn't be able to do the things I did in this course by following the tips provided.

Good introduction course on solidity and Ethereum. It covers all the topics to get started with smart contracts. Some prior programming knowledge is a must to completely understand the programming parts. Overall the course is a good launching pad for learning smart contracts.

The course content is good and gives a basic intro to solidity and remix IDE. One thing that I feel is missing is practice. I think small programming assignments should be added in week tests which will encourage students to try and code things themselves.

The overall course is really good. I get to know multiple commands and functions of smart contract. I would like to request to add Lab or short Solidity programming assignment after each section to get acquainted with solidity programming. Thank you.

Everything that have been taught is certainly very helpful. Just a thing that i would love to have improved is that they should be providing more hands-on coding and evaluating it, so we come to know more in-depth about solidity.

It's great although the learning references start to get outdated. This becomes an opportunity to understand how the solidity language has evolved (from version 0.4.x to 0.8.x) and what features have become a game changer.

I liked the course but the final automatic evaluation's very ambiguous because when there are failed tests it doesn't describe which test actually failed, so it can be very difficult and frustrating to debug those problems.

It would have been nice if there had been some hints where errors occurred in the evaluation of the programming task. When you accomplish a task on your own, you tend to make systematic mistakes that are hard to recognize.

Every video is speech based which makes the presentation somewhat boring. Instead if some slides with summarized key points and simulations were added at every presentation, it would have been much more interesting.

Thank you very much for the course. This is already very complicated for those of us who are about to discover the world of programming. So, I will take this course more as a starting point than as a destination!

Well structured course and good content, however the method of teaching is not very engaging. Maybe you can add more diagrams and pictures and explain the content in a dynamic, more interesting way. Thanks!

Good course

But the coding could've been explained better, some complex problems are covered in a light manner

A strong base has to built on solidity first, then the programs would be easier to understand

The course is really good. But the final programming assignment wasn't challenging enough. Although I might be judging too early considering this is a part of a specialization.

Overall a good experience, but if more help available on course project, it would have been better. No response from teaching/supporting staff in forum. Otherwise, it's good.

The Programming part could have been better. Almost, everything was written and didn't help me much in learning any new thing or gave me experience to write code on my own.

Great course. I hope the working excercises would have been more (But may be because I code a lot). But for beginners who have no idea of coding the course is excellent.

The final project was a little difficult because if doesn't show where the mistake is, besides that the course is just great to have a first experience using IDE remix
