Getting into Blockchains is hard!
There is a whole lot of hype around Blockchain. But how does it work? What is a smart contract? Why is everyone so excited about DAOs? And what does all of this have to do with cryptocurrencies?
And most importantly, how do you program for a blockchain network?
We have spent the past couple of years developing and improving this in-depth online course to teach developers about Blockchain and how to develop decentralised applications, or DApps, on the Ethereum platform.
About This Course
This online course teaches software engineers the basics of blockchain technology as well as languages and tools required to build decentralised applications on the Ethereum platform. This course is aimed at experienced programmers, introducing everything needed to understand the technology, write smart contracts and build applications that interact with them.
Participants will learn about the Ethereum platform, the programming language Solidity, how to use web3 and the Truffle framework and lastly, how to tie everything together. Step by step, participants build a fully functioning decentralised application, deploy it and test it.
This course was developed in response to the daily requests we receive for expert developers in blockchain projects.

The course covers the very basics of blockchain technology, from data structures to live projects. Serves as both a reminder for participants who know the basics and a clear introduction for those who don't.
- What is a blockchain?
- What are transactions and blocks?
- How do P2P systems operate?
- The most prominent consensus mechanisms
- Difference between private, consortium, and public networks
- What does the data structure look like?
- How do Smart Contracts work?
- What is the Ethereum Virtual Machine?
- What is a Hash?
- How do public/private keys work?
- What is a Merkle tree?
- What is the double-spend problem?
The window into any blockchain network is the node. This course teaches students how to run a node and how to install, configure and use the most common Ethereum clients.
- The Ethereum ecosystem, DApps and DAOs
- What is Mist and how does it work?
- What is Ether, an account, a Faucet?
- Compile, deploy and instantiate contracts
- Configuring, running and working with the go-ethereum client
- Account management and mining
- Understand the different stages of a contract deployment
- How to interact with a contract once deployed?
- What does the setup process for a private network look like?
The most prominent language used for the development of smart contracts is Solidity. The course covers all aspects from value types and inheritance to more exotic features and optimisation.
- Contract classes, Functions and conditionals
- Inheritance & abstract contracts
- Types & Optimisation
- Global Variables
Web3 & Truffle
The toolkit to aid development of decentralised applications is growing. This course introduces the two most currently relevant and covers everything from installation and setup to custom configuration and scripting.
- Building an interface to interact with a smart contract
- Setting up event-driven interfaces
- Adapting Truffle’s default behaviour
- Write functional tests for smart contracts
- How to manually test contract functionality?
- Instantiate web3 and communicate with a contract from an HTML page
- Use client side signing and remote nodes for light DApps
- How does web3 and truffle work with Angular.js?
This project(s) work will guide you through the steps required for the development of a sophisticated decentralised application, including a smart contract backend system and a full frontend. You get one full week for each project. That is how much we think they matter.
This contrived first project deals with Ether transfers. You will get in touch with basic Solidity syntax, and work with basic transactions and smart contract interaction concepts. You are going to learn how to transform a narrow-use smart contract into a global utility, how to protect your users and how to protect your smart contract from your users.
The second project demonstrates, by trial and error, how the public nature of Ethereum, gas price and mining delays cannot be ignored when coding in Solidity. This project looks and feels more real-life than the first project. Further, you will learn the art of balancing interactions and actions between client-side and chain-side. If you choose to, you will be able to adjust the specifications to your liking and, for instance, experiment with multi-contract interactions or attempt a rudimentary business model.
The third project is a well-known child's game that, although disarmingly simple, requires careful considerations when played on Ethereum. You will reapply teachings learned in the previous projects while ensuring you do not ruin your players' finances. How low can you go?
In addition, you will be presented, out of the blue, with a few challenges that, when completed, give you the opportunity to not only brag, but also reconsider your assumptions.
You can hammer out a transaction. But can you chisel a transaction?
Can you guess randomly generated numbers? Should you speed-read a smart contract, or take your time?
Don't you like it when money appears in your wallet out of nowhere?
You read about contract exploits, but can you exploit one yourself?
Teaching & Communication
The course is delivered through a mixture of reading material, videos, quizzes, various exercises, challenges & projects. In addition, students are invited to communicate and collaborate in a course dedicated Slack channel. Your expert instructors engage in active mentoring to guide you through the course and students are encouraged to help one another.
Our instructors tutor and mentor throughout the course duration and during the exam period to help clarify course content and assist you with reaching your individual learning objective at your pace.

How does the Course work?
The course consists of 12 modules and is designed to be flexible and self-paced. You can choose your individual start date within your subscription period and study the material whenever it fits best into your daily routine.
The estimated workload is about 8 to 12 hours per module, depending on the challenges you pick.
Exam and Certification
At the moment you feel ready to start your exam, you can book your individual 5 weeks exam period and submit your final exam whenever you feel ready during this 5 weeks window.
The pass mark is fairly high and requires an average of 80% or more. In case of failure, it is possible to retake for a small fee. The certificate is publicly verifiable on the Ethereum blockchain.
