This 12-week 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 programmers with at least 1 year of experience, introducing everything needed to understand blockchain, write smart contracts and build decentralized applications that interact with Ethereum. Hands-on 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. 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 includes one-on-one mentoring and support from expert instructors.

This course has been developed to meet the growing need for blockchain-focused QA Engineers. Everyone is talking about blockchain technology, especially in relation to smart contracts, which have the power to touch almost every area of our lives. Ethereum in particular has 30 times the number of developers involved in its ecosystem than its nearest competitor does. But where are all the QA engineers? It's a sad fact that many projects have gone live with little or no formal testing by anyone other than the person who developed the dApp. The consequence of working with bleeding-edge technology combined with a lack of formal quality assurance is that there have been bugs. Some have been minor, but others have caused the loss of hundreds of thousands of dollars. A project built on the Ethereum blockchain may look identical to a normal, centralised application or API. But the differences are so great that the whole quality assurance process needs to be approached in a completely different way, requiring the QA engineer to dig deep into the code and conceptualise ways of pushing the underlying smart contracts to their limits with different data inputs and variations in network conditions and transaction fees. This course has been developed to meet the growing need for blockchain-focused QA Engineers. The course provides hands-on examples of this type of rigorous exploratory testing and explains how to set up different test environments in order to do it. Assuming the QA engineer – like any modern testing professional on an Agile project – is involved at the earliest stage of the project, he or she needs to ask questions about transaction fees, latency, privacy and data compliance. You will learn to specify acceptance criteria that can later be used as the basis for automating your acceptance tests, with quizzes, screencasts and exercises to test your understanding of the requirements. Test automation is a critical part of the QA process. You will learn about the most common test libraries and how to run your suite in a continuous integration environment.

As you can imagine, someone needs to do the actual coding when companies move to experiment and replace their legacy systems with blockchain implementations. This is the first advanced online Hyperledger Developer course worldwide. With training, you could gain a serious first-mover advantage. Whether you are interested to get a head start or you want to switch careers (or you maybe even have an offer already?) this course provides a full launch into blockchain and Hyperledger Fabric. This course is designed to teach you everything you need to know even if you have no previous experience with blockchain technology. It covers basic blockchain theory, Hyperledger Fabric infrastructure, chaincode and enough Go to get you going. If you get certified we would also be happy to match you with an interested company wherever we can. The whole 8 weeks course is online. We have videos, texts, visualisations and lots of practical exercises. A new batch of content lands at your feet every week. In our experience you will need 8-12 hours a week to keep up. But if you need more time you will have another 12 weeks after the course to catch up and get certified.

Hyperledger Sawtooth is a modular platform for building, deploying, and running distributed ledgers. It includes a novel consensus algorithm called Proof of Elapsed Time (PoET), which targets large distributed validator populations with minimal resource consumption. Its modularity makes it especially interesting for developers and enterprises. Sawtooth also allows us to define rules for transactions and smart contracts tailored to individual needs. This is a permissioned network with great capacity for scalability. At first glance, Sawtooth might seem unusual to experienced blockchain developers who have never seen concepts such as “transaction families” before. However, a closer look reveals that despite looking different, such concepts can be used to implement familiar ones in more flexible and modular ways. This online Hyperledger Sawtooth course offers developers an opportunity to become proficient with blockchain and Hyperledger Sawtooth. After reviewing the fundamentals of blockchain technology, we will learn how Hyperledger Sawtooth fits in the blockchain environment, discovering its architecture, tools and transaction families. Next, we will look at different SDKs to eventually be able to analyse real-world examples and identify the most important aspects.

The Quorum™ Specialisation Course is an extension of the B9lab Ethereum Developer Course and is for experienced Ethereum developers. The aim of this course is to give you hands-on experience by working directly on the Quorum platform. By the end of the course, you will be able to write smart contracts and build applications that interact with Quorum. The course will also deepen your understanding of Ethereum and unpack how Quorum adds privacy and enhances performance to a default Ethereum system.
