Acerca del Curso

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.

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.

T​he 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.
