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.

Videos far too short and superficial. The student needs to be given many, very small coding assignments to learn all the relevant keywords to use on the final project.

創建者 Howard M S


The material felt more out of date than blockchain basics, i think because Remix keeps changing. A warning about this early on instead of later would have helped.

創建者 Reid T S


Course materials need to be updated. Uses old version of solidity, so not up to most modern standards and features. Some quiz questions seem irrelevant

創建者 Lagadic A


Less interesting than the "Basics" session (from a developer point of view).

Yet the major solidity words are explained.

創建者 Gary T


Without at least an indicator of which area of final project fails grader it gets difficult to know what to look for

創建者 Matteo L


Not being a native English speaker, I found a bit of difficulty with the teacher's colorful pronunciation.

創建者 Yves T


Course is good but there is clearly a bug in the evaluation process of week 4. You have to work on it.

創建者 Keith M


Very basic. Final programming assignment pretty much spoon-feeds you the answers through the hints.

創建者 Nanda K


Good content, but I wish it was presented better. The teacher blandly reads out from a prompter.

創建者 Maulik P


The explanation of the keywords in the example smart contracts should be given more clearly.

創建者 Vlad S


I would have liked a more in-depth approach for the Solidity language courses.

創建者 Nofil A


I think there should be more practice to get hands on solidity .

創建者 Jeremiah F I


Nice course but there is need for improvement in course content

創建者 Marco M


I think there should be more exercise.

創建者 Bornface S


I leant a lot, with real challanges

創建者 Jens R


The course was too developer-oriented, and too basic at that. A lot of topics were about coding style guidelines (which I do not particularly care for), or concepts from object-oriented programming that I was already familiar with. I was hoping to get a better insight into how smart contracts work "under the hood" (e.g., EVM design and execution); instead I got the "black box" perspective from a programmer's point of view. Some of the questions and/or answer options in the quizzes were ambiguous, resulting in mistakes that are merely due to unclear question/answer formulation.

The course is good but the content to read is too less to understand everything. It becomes a necessity for a person to refer to a different source like Youtube.

創建者 Ashwin


The instructor does not know what she is doing or saying. She does not explain the concepts properly. This course is useless. I would expect a refund.



As I wasn't had any coding background it was hard for me to learn solidity

there are some topic which should have been more elaborated :(

創建者 Shelly H


It feels like the professor is reading from a text book!

創建者 Jakub C


Old version of Solidity asking for major update.

創建者 Jordi C


Passing this course is all based on completing a programming assigment in Week 4. If you fail that assigment you will fail the course. So, if you don't have a programming background and/or interest in learning to develop smart contracts (not simply understanding their role and use) then you might struggle at the very end. I feel that this should have been made clear in the course description; I want to learn about Blockchain but have little to no interest in becoming a smart contract developer (for which this course will not prepare you, anyway).

創建者 Sudeep C


The resources for the exercises have not been described at all..I was unable to find the .sol files or the IDE installer. Bounced around in the discussion thread and noticed that others too were having the same issues but looks like you have decided not to take the inputs seriously.



It was a really bad experience, the instructor seems to be reading everything from the screen placed near the camera, and there was no clear explanation,

Unfortunately, no support is given to the learners. I had too much time for just asking questions that have never been answered. Wasted my time and money
