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 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.

Some basic learnings to be had here, and the final project they finally ease you into some programming. There are a few mines of code you will have to write yourself. A few lines of code are basically given to you, and the others you will never figure out based on what they "teach" you (unless you are already experienced, in which case, why are you here?). Someone on github has it up. Very disappointing course.

I love to learn with Bina, however the content is outdated. I am unable to use the code provided with the currently available Remix IDE. Unfortunately, I must abandon this course.

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 :(

Short videos, not enough explanation to actually learn Solidity. Outdated.

Outdated, so it turns useless, all explanations are based on a version of REMIX that is not current years from now. At the begining of each video , the instructor points the items you "should" be supposed to learn, and in the next minutes, the explanations turn so far from practice, that you end up not understanding anything.

Im looking for another course.

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.

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

Programming classes pointing to an external source, should not be outdated. Extremely frustrating.

Very good course introduction to prgramming smart contracts for Blockchain distributed applications. In my case I wanted to get better professional opportunities by introducing into blockchain development form enterprise applications, and this course just put me in the right direction of designing and building blockchain based bussiness logic. One can relate and appropriate concepts that are dispersed in the web ecosystem in this great education place. Thanks Coursera.

A well designed course on smart contracts is so useful in learning all about smart contracts. The reference materials suggested is a must read for better understanding of the concept and the overall technology. Basic fundamental things are well explained in the videos and the tests will help in checking the actual understanding and the learning. Overall a very good course which I would recommend anyone who wants to learn about Smart contracts.

The instructor is very detail oriented and perfectly balances speed with detail. However the last assignment i.e project on creation of auction is not very helpful. There is no way to get details on why the code is failing. For eg, in my case I was able to compile the code on my compiler but it wasnt happening on the coursera interface. and there was no way to find out what the error was.

Awesome course with all the hands on tool and tips required with perfect amount of pace and exercises to teach get a non developer student enough to be able to converse and understand the language of Blockchain Smart Contracts Developer in Solidity! Loved this course.. Assignment was little challenging with a trick - overall Great Learning Experience! Thx to Ms. Bina R! Kudos to you..

When i started the course 'Smart Contracts Programming' from the staring of the course i have got information about the topic in clean and filtered manner from standard lecturers..The Excersise problems and Project work were really Good and Easy for beginners like me. ! Yes i enjoyed the learning journey and i really suggest it for my friends......Thank You team Coursera....!

Excellent course to begin with solidity programming for smart contracts , understanding the steps and standard policies for smart contract coding. Also introduces you to the Remix web IDE and it gives an introductory experience for coding and deploying the smart contracts. A very well set up course with all necessary details provided.

I am impressed with the flow and design thinking explained in the course to develop a smart contract. The content has step-by-step process of structuring the requirement, compile using different version and deploy in Remix IDE. Overall a good experience, would recommend people.

These Kind Of Courses Are What Coursera Exactly is meant for . Clear, precise and guiding.

The Course is specifically designed for guiding us through what smart contract is and how to write in solidity . The Tutor was excellent in the explanation and project design.

Great introduction to Smart Contracts and to Solidity Programming. After completing the course you will have a practical idea of how a smart contract looks like and you will be able to implement basic but powerful smart contract. Very informative/pragmatic videos!

It's a good course, more focused on programming. I think it gives good bases for developing smart contracts, but you have to learn from other sources if you want to have a better programming background in Solidity if you want to focus on the backend.

This course build on the previous one. Again this is not a difficult course (actually the required demand is not high). As with most educational endeavors, the best way to master these stuff and get better is to do more work that the minimal required

For a Blockchain newcomer like me, the smart contract course is detailed and very good. Small code assignments can be added to the course lessons to make them more practical. Last project may include more features. I am very much satisfied. Thanks.

This course gave me a thorough understanding of designing, developing and deploying the smart contracts. I would definitely recommend this course to anyone who just started with Ethereum or Blockchain smart contract to go through this course.

I always wish to find such a platform, where i can test my skills.

And i am surprise to know coursera has all the functionalities and courses i was looking for.

i really enjoyed synchronizing my knowledge with a professional certification.

Another excellent course with a step by step introduction to programming smart contracts using Solidity. This course has given me the confidence to explore the Remix IDE and Solidity documentation to program more complex smart contracts.
