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.

Very interesting introduction to Solidity, Remix and Smart Contracts. I find it a little short in terms of practice but very well structured and presented.

Better than the first course but still a little too high-level and easy. Wish they actually got into the more advanced features of the Solidity language.

Course is a little outdated, but give a general good introduction to Solidity programming language. The feedback on the auto grade could be better

Great content, a bit difficult to understand the teacher. Speed is high. The links to ext. resources are good.

And knowledge in coding would help.

For further improvement the programming assignments, should be downloadable as text files. As copying from the PDF is tedious and error prone.

This was really eye-opening. I especially enjoyed the resources after each lesson, as they took me off into the wide world of smart contracts.

The course was really good, the only reason I don't give five stars is because one the final exam the questions/tasks were not really clear.

project lacked some direction as the functionality was not that clear through out had to go to various outside sources in order to complete

As a concise intro - it is perfect. I did think it could go a bit more into the 'why' rather than the how, but overall - very effective

Useful course to understand the fundementals of Solidity language and the Remix platform. Some more hands on exercise will be helpful.

Good introduction to Smart contracts as a concept.

Good overview and approach to designing Solidity based smart contracts on Ethereum.

Although I have some experience with programming, but many concepts in smart contracts are new and need some time to slowly digest.

This course was surely one that provided me with the documentation and the tools in order to execute and develop a smart contract.

The course was really good, although the programming assignments could've been a bit more challenging (the hints gave it all).

Very informative, however the final project was a bit finicky being handled by the autograder due to whitespace formatting.

Good for an introduction to Solidity. If you're familiar with coding, might as well read it yourself, will be much faster.

I learnt a lot about Solidity and smart contracts, It was also really useful to have the first experience with REMIX IDE.

Overall the course was good but If you are not already a coder. It's better to learn coding before taking this course.

Very informative course. Coding Assignment results can be little more descriptive so as to know where the error is.
