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.

TOP REVIEWS FROM SMART CONTRACTS
by DMDec 17, 2019
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.
by 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.
by 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.
by SDMay 20, 2020
The course is really good. But the final programming assignment wasn't challenging enough. Although I might be judging too early considering this is a part of a specialization.
About the Blockchain Specialization
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.
Frequently Asked Questions
When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
- The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
- The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
What is the refund policy?
If you subscribed, you get a 7-day free trial during which you can cancel at no penalty. After that, we don’t give refunds, but you can cancel your subscription at any time. See our full refund policy.

You'll be prompted to complete an application and will be notified if you are approved. You'll need to complete this step for each course in the Specialization, including the Capstone Project. Learn more.
Who is this class for?
This course is for anyone interested in designing and developing smart contracts. Along with other courses of the Blockchain specialization, it provides the foundation to design and develop decentralized applications (the focus of the third course) on the blockchain.
Are there any prerequisites?
