2. Blockchain Specialization (Coursera)

This is a comprehensive course offered by Coursera that covers everything from the basics of blockchain technology to more advanced concepts such as smart contracts and the Solidity language.

The course is divided into four courses:

  • Blockchain Basics
  • Smart Contracts
  • Decentralized Applications
  • Blockchain platforms

Each course is around four weeks long and you’ll need to put in around five hours of work per week to complete it.

It’s taught by Bina Ramamurthy, by the University at Buffalo and the State University of New York.

Key Features:

  • Comprehensive coverage of blockchain technology
  • Taught by experienced instructors
  • Offered by a reputable institution
  • Come in 4 long courses that cover
  • Affordable pricing at $45 a month

Bottom Line:

This is a great course for those who want to learn about blockchain technology in-depth. However, it is best suited for those who already have some experience with programming as the course does assume some prior in depth knowledge.

3. Ethereum: Building Blockchain Decentralized Apps (DApps)

If you’re looking for a course that’s more specifically about the Solidity programming language and Ethereum development, then this is the course for you.

The course is taught by Thomas Wiesner, who is a software engineer with over 20 years of experience.

It’s aimed at helping students learn the steps in building decentralized applications (DApps) and implementing smart contracts in Solidity on the Ethereum blockchain.

To do this, you’ll learn about Solidity programming, development tools, best practices, and more.

More specifically, you’ll learn how to use your Solidity programming skills to deploy your own smart contracts, and even learn how to use the Truffle Framework.

The Truffle Framework is a set of tools that gets developers from ideas to dApps quickly and is commonly used for development.

The course is four hours long and is available on demand so you can complete it at your own pace.

Key Features:

  • Taught by an experienced instructor
  • Focuses specifically on Ethereum development
  • Teaches you how to use the Truffle Framework
  • Available on demand

Bottom Line:

This course is great for those who want to learn about the Solidity programming language and Ethereum development specifically.

It’s taught by an experienced instructor and covers all the important aspects of development.

4. Blockchain: Learning Solidity (LinkedIn Learning)

This course is best suited for those who want to learn about Solidity programming, but don’t necessarily want to focus on Ethereum development.

The course is taught by Emmanuel Henri, an executive with over 20+ years of programming and design.

In the course, you’ll learn about the basic concepts of the Solidity programming language, data types, functions, and more.

If you’re thinking about getting into a course focused on learning solidity, this is a great choice.

Here are the exact learning objectives you’ll learn:

  • Installing Solidity
  • Solidity programming basics: types, variables, functions, and conditionals
  • Creating smart contracts in Solidity
  • Setting variables
  • Adding modifiers
  • Finalizing functions
  • Testing your contract

While other courses gloss over these topics really quickly, this course pays more attention to the Solidity programming skill you’ll learn and how to creatively write your own code.

The course will also cover the Solidity ecosystem and the Solidity programming syntax and advanced concepts such as source mappings and how to apply them to build your very own smart contracts.

The course is available on demand so you can complete it at your own pace.

Key Features:

  • Taught by an experienced instructor
  • Focuses specifically on Solidity programming
  • Covers the Solidity ecosystem and syntax
  • Available on demand

Bottom Line:

This course is great for those who want to learn about Solidity programming specifically. It’s taught by an experienced instructor and covers all the important aspects of development. If you’re looking for a good solidity tutorial, go for this.

5. Solidity Path: Beginner to Intermediate Smart Contracts by CryptoZombies

This course is perfect for students who may not have the money to invest in a course with a solid curriculum, but still want to follow a program to learn how to code their own smart contracts.

I like and recommend this course to complete beginners because the entire course happens in a read-made development environment so your learning is really focused.

Personally, I just really like how they gamified the way you can learn Solidity through very concrete steps.

However, it doesn’t really stop at a beginner level. You can continue to do the follow-up course which will take you to an intermediate level.

Key Features:

  • Highly-gamified learning experience
  • Write an oracle to create Ethereum smart contracts and deploying on the Ethereum blockchain.
  • Completely Free
  • Self-directed learning

Bottom Line:

This course is best for those who want a free and gamified way to learn Solidity programming learning how to build a smart contract.

While it doesn’t go into as much depth as some of the other courses on this list, it’s still a great way to get started with coding your own smart contracts.

6. Become a Blockchain Developer Nanodegree (Udacity)

This course is best for those who want a Nanodegree from Udacity that will train you well in the varied skills needed in learning solidity.

Here are a few milestones covered in the course:

  1. Blockchain Fundamentals
  2. Ethereum Smart Contracts, Tokens and Dapps
  3. Blockchain Architecture
  4. Dapp with Autonomous Smart Contracts and Oracles
  5. Capstone Project

In addition, you’ll get access to a number of resources, including a community forum where you can ask questions and get feedback from your peers.

The course is self-paced so you can complete it at your own pace, but it’s recommended that you dedicate at least 15 hours per week to the program.

Key Features:

  • Covers all the Solidity development fundamentals and smart contracts
  • Includes a capstone project to help you apply what you’ve learned
  • Write multiple dApps on Ethereum
