Remix is an online IDE for Solidity smart contracts. Truffle is the most popular framework for developing Ethereum Dapps. It is written in Nodejs and has a strong community behind it. It has recently launched its own online academy and its own conference. Truffle makes deploying smart contracts a breeze. Without Truffle, we would need to combine many different tools. The official Docs are very good, and if you prefer videos you can checkout my Introduction to Truffle.
Ganache is a local Ethereum Blockchain used for development. With Ganache, you just need to run a command to start a local Ethereum node and have 10 addresses pre-funded with Ether fake Ether of course , which is very handy for development. Metamask is an Ethereum wallet that is packaged as a browser extension.
It is used by Dapps when requesting a user to sign a transaction. Transactions might send ether from the user address to another address, or simply change the value of a variable in a smart contract.
Metamask is available on Chrome and Firefox but the Chrome extension is more popular. Smart contracts are the main building blocks of Dapps. There are small programs deployed on the Ethereum Blockchain that run autonomously once deployed. It just runs forever, outside the control of anybody. Solidity is the main language that is used for writing smart contracts. It has a syntax that is similar to Javascript but the similarity is just cosmetic. There is an intermediary compilation step, in which Solidity code is compiled to a bytecode that the Ethereum Virtual Machine the component of Ethereum that runs smart contracts can understand.
Also, contrary to Javascript, Solidity is a typed language, which means that you need to specify the type of each variable. Contrary to Javascript and most languages, Solidity is much more primitive and much more limited. Expect some surprises in your learning process! As a first step into Solidity, a lot of people like to use CryptoZombies. Cryptozombies is a game designed to teach you the very basics by creating an army of Zombies in a smart contract. If you are into learning games, you might also enjoy Ethernaut , another game where you have to hack a smart contract.
Next, I would recommend to spend some time reading the official Solidity Documentation. It is the most comprehensive resource on the topic and it is regularly updated. On my Youtube channel you can find some other resources for learning Solidity and smart contracts. The author is quite knowledgable in Solidity and covers some advanced topics. You might also want to learn about how to write safe Ethereum smart contracts.
In smart contracts, you manipulate other people money, so you will be the target of hackers. These are good resources for learning about security in Solidity:. If you want to to get more tips about learning Solidity, read my article on what is the best way to learn Solidity. Because smart contracts are not very user-friendly we cannot ask end users to directly interact with them. Instead, we need to build easy-to-use UI for users.
Before reading this article, you might have heard previously of Cryptokitties. Cryptokitties is this game where players buy, breed and trade kitties. This is built on Ethereum and is a good example of Dapp. First, we have the Cryptokitties website. This is the main interface interface for user. The website backend is deployed on private servers, and the frontend is a regular webapp. Nothing new here. Finally, we have the Cryptokitties smart contract, which is where the game data is stored.
For example, if a player buys a kitty, this information will be stored in the Cryptokitties smart contract. The smart contract is deployed on the Ethereum blockchain. These 3 parts interact together to form a Dapp. In order to build your own Dapp, you need to build these 3 parts and make them communicate which each other.
You can start by following my Free tutorial series on how to build a Todo list Dapp on Ethereum. This is a 8 steps tutorial where we will build a complete Dapp with the smart contract and the frontend, starting from the smart contract, and all the way up to the frontend:.
Plus it will have 2 bonus series on how to integrate React in a Dapp and how to use Drizzle, the frontend framework of Truffle. If you are looking for online courses for learning to build Ethereum Dapp, you can check out the below links:.

But before you do that you need to prepare yourself for these interviews. Employers will ask you to explain how a Blockchain work, and what are the different elements of Blockchain.
Since Blockchain was created by Bitcoin, the 2 are often mixed together in Blockchain interviews. You can check out my article on what are the Top 12 questions in Blockchain Interviews.
When I first got into Blockchain, I stumbled upon this book. I read it end-to-end in a couple of days and it made me become passionate about Blockchain. Throughout my journey in Blockchain and Ethereum, it helped me a lot to have read this book. Thanks to it, I acquired a good grasp on the Blockchain technology and Bitcoin.
Knowing that most Blockchain systems and somehow based on Bitcoin, it helps a lot to have a good foundation there. You can buy the book from Amazon or read it for free on Github. The author recently released an updated version, following the latest development of Bitcoin Segwit.
Make sure you buy this version. General job boards not specifically focused on Blockchain also usually have a decent numbers of Blockchain jobs:. More on that in the next section. At some point in your journey of becoming a Blockchain developer, you will certainly need some help. Fortunately you are not alone and there are a lot of online communities where you can ask for some help. The Ethereum stack exchange is great place to get some answers.
Another way to get help is to meet other developers in real-life. It is a short course for beginning blockchain developers. You will get to know the basics of the blockchain as well as the ways it is used by Hyperledger Fabric and IBM.
It will be of interest to those who are just starting out their blockchain development careers. Also, it is free of charge and very short. It will take you just around two hours to complete the course.
Darren is an entrepreneur and developer. Before joining Lockheed Martin, he has worked as a developer and analyst at several US companies. He also has working knowledge in a number of programming languages, including Java, MS.
It lays out the basics of Blockchain, in general, and gets into how Hyperledger Fabric and IBM are leveraging this technology. The course is laid out well with all the refinement one comes to expect from IBM. However, I have to say, it is quite personable as well.
The chapters are well defined, short enough to squeeze into a busy schedule, and quite understandable, even to the lay person. Personally, I found them to be a bit simplistic at first. However, as soon as I lost focus, I was pulled back into the straight and narrow by a Checkpoint question and was reminded that I, in fact, do NOT know it all.
While simple, this knowledge check did show I had a few areas I needed to review. Second times the charm, right?? It is a more advanced course on the blockchain from IBM compared to their Blockchain Essentials course. This one is suitable for those who already know the basics of the blockchain and want to dive deeper into the topic.
Of course, it is more challenging than the Essentials course. The course will take you roughly six hours to complete. However, the questions asked were on point for the desired objectives of each chapter. Cryptozombies is an online game that teaches you how to program in Solidity. Jeffrey is a professional web developer and writer at Steemit Platform. Cryptozombies is really similar to basic programming websites like Code Academy and Code School. It gives you a quick and unintimidating look at the language with bite-size lessons you can complete in the browser.
It takes you through creating a game like Cryptokitties. If you want some initial experience you can use the sites I mentioned above, but my favorite programming course for beginners is freeCodeCamp. The first lesson has 15 chapters, and can be completed in about an hour.
Each chapter contains a small challenge that you have to complete in the built-in editor. Overall this was a really fun way to get a glimpse of coding in Solidity — definitely worth a shot for anyone who is curious. The course will give you knowledge on blockchain fundamentals, and its history, combined with practical applications of Hyperledger Fabric. Go for it if you want to get a well-rounded knowledge of the blockchain and get advice from people who are professionally involved in Hyperledger Fabric projects.
