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.

Smart Contract Basics
The purpose of this module is to introduce the reasons for a smart contract and its critical role in transforming blockchain technology from enabling decentralized systems. We will explore the structure and basic concepts of a smart contract through examples, and illustrate Remix (remix.ethereum.org) web IDE for deploying and interacting with a smart contract.

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.
par HTApr 8, 2019
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.
par ANJan 11, 2019
Great course for the beginners. Its gives an overview of smart contract, Solidity , Remix IDE. it definitely gives a lot of confidence to the trainee upon completion of the course.
par AIDec 9, 2018
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.
par ASJun 18, 2019
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.
par TKSep 4, 2019
I was once lost on what is a smart contract, now, its more clear. I am more educated thanks to these very insightful videos and word for word explanations of the videos!
par KNJul 30, 2019
some resources must be reordered with the vedios for the student to keep on trying the code in the vedio\n\nthanks alot for the course content its simple and progressive
par GMDec 2, 2018
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
par FLJan 12, 2019
Everything great, however the last assignment could have some more guidance, or stepped approach. I had to do a lot of guessing instead of being sure of what to do.
par AANov 15, 2018
Good course, well explained for beginners. Along with the course, pay attention to reading section especially referred youtube course of solidity for more examples.
par YHJun 28, 2018
Good class. It can be even better if more coding assignments can be added. Currently there is only one coding assignment, which makes the course a little too easy.
par AGSep 18, 2018
Exactly the right level, i'd expect. Not a course to learn how to be a programmer, yet enough info to have a basic understanding of smart contract and Solidity.
par JAAug 3, 2019
Some concepts are under-explained, but an overall strong foundation to Smart Contracting. The course directs students to many external resources that can help.
par ADAug 1, 2018
This is one of the toughest course for me. Lectures and supporting materials helped a lot to complete this course. Thank Bina and all supporting staff.
par MMSep 2, 2018
I know now why Smart Contracts are important. I really enjoyed the course and look forward to the remaining courses. I am really digging this stuff!!
par PPOct 28, 2018
This course is excellent, It gave good understanding on writing smart contracts in Solidity. Quiz and the graded Assignments are quite interesting.
par RMFeb 23, 2019
Well structured, Final assignment requires you apply the learning from all the weeks. Programming language experience helps but is not necessary.
par RBSep 4, 2019
For further improvement the programming assignments, should be downloadable as text files. As copying from the PDF is tedious and error prone.
par JLJul 9, 2018
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.
par STDec 25, 2018
It explains in depth about smart contract.\n\nJust one thing, sometimes watching a coding video is boring. Would be more fun to code ourselves

À propos du Spécialisation Blockchain
This specialization introduces blockchain, a revolutionary technology that enables peer-to-peer transfer of digital assets without any intermediaries, and is predicted to be just as impactful as the Internet. More specifically, it prepares learners to program on the Ethereum blockchain. The four courses provide learners with (i) an understanding and working knowledge of foundational blockchain concepts, (ii) a skill set for designing and implementing smart contracts, (iii) methods for developing decentralized applications on the blockchain, and (iv) information about the ongoing specific industry-wide blockchain frameworks.
The specialization covers a range of essential topics, from the cryptographic underpinnings of blockchain technology to enabling decentralized applications on a private Ethereum blockchain platform.
It is ideal for programmers and designers involved in developing and implementing blockchain applications, and anyone who is interested in understanding its potential.
