What Will You Learn?
Ideally, you should have at least another motivation. For example:. Do you want to find a job at a Blockchain company, or do you want to launch your own Blockchain project? The Blockchain industry is growing at a breakneck pace, and there are a lot of opportunities to benefit from it. Blockchain entrepreneurs will capture the largest share of this value, but developers can also expect to benefit from this growth. For Blockchain developers, salaries are on average , USD a year in the US, according to a survey of computerworld.
Another benefit you can enjoy as a Blockchain developer is more options for remote jobs compared with non-Blockchain developer jobs. As an entrepreneur, one of the main advantage of Blockchain is easier access to funding. Thanks to the innovative funding mechanism of ICOs, some blockchain projects have raised millions relatively. This being said, be aware that the heydays of ICOs are over and with increasing government scrutiny around the world the funding has dried up a bit, but its still easier than in other industries.
The other benefit you can enjoy as an entrepreneur is easier access to users. Blockchain is a new application platform and your app does not need to compete with a ton of competitors to get users. CryptoKitties famously became successful overnight when it launched in late Most blockchain developers belong to the second category. This article is mostly for people who want to build applications on top of the Blockchain, but developers who want to build Blockchain software itself will also find this article helpful.
It is essential that you set yourself a time limit. Specify clearly the objective and the deadline. There are more than blockchains registered on coinmarketcap and new one are created every day. You need a sane way to navigate this never-ending flow of information. Actually, you should focus on the few Blockchain technologies that really matter and avoid being distracted too distracted by the others.
Bitcoin is the most stable and battled tested Blockchain technology. It has reliably processed transactions for almost a decade, and its the most used Blockchain. However, its only capable of processing simple transactions and is too limited for many applications. Ethereum was built to solve the limitations of Bitcoin and allows to run small programs called smart contracts.
Think of it as a virtual machine put on top of the Blockchain. The Blockchain guarantees the integrity of the data, and the smart contracts allow to run any arbitrary computation, making Ethereum much more flexible than Bitcoin.
EOS was built as a modern alternative to Ethereum. Like Ethereum, it can run smart contracts. However, unlike Ethereum transactions on Eos are free. Finally, it is much more scalable than Ethereum. It might appear than EOS is the best choice. Network effects mean that a network becomes exponentially more valuable as more users join. Facebook is a good example. Once Facebook has reached a certain critical size, it left no chance to competitors because it would be too inconvenient for new users to be isolated of their friends on Facebook.
Likewise, for Blockchain network effects also applies because users want to be able to make transactions between each others.
Network effects also applies to the developer communities that grows around each Blockchain. In order to develop applications in a reasonable time and cost, we need not only a rich and mature ecosystem of developer tools and libraries, but also a vibrant community of competent developers. This can only happen if the community reaches a certain size. If you decide to pick Ethereum, before you rush to learn the tech, the next step would be to get more familiar with what kind of applications developers are building on it.
There are more than applications built on Ethereum and new ones are released every day. We call these applications Decentralized Applications, or Dapps. A great way to discover popular Dapps is to visit a Dapp list website. I personally prefer DappRadar because its easier to access their Dapp lists and also because they have all sort of interesting rankings like the Dapps with the most DAU daily active users or with the most transactions per day.
They are popular for trading lesser-known ERC20 tokens which lack liquidity. Gaming Dapps are mostly what we call collectible games. Users first buy characters from the game creators and then interact with other characters in different ways: fighting, breeding, etc… Compared to non-Blockchain games, the most distinctive feature of Blockchain games is the economy part.
Thanks to the Blockchain, players are able to trade their characters freely with other players, without ever worrying about the interference of the game creators. The most famous gaming Dapp is CryptoKitties , where players collect cats that can breed. Gambling Dapps were among the first kind of Dapps to be built on Ethereum. Fomo3D is one of the most famous, where players have to keep investing ether to avoid letting the last player win all the money.
Be aware that gambling Dapps on Ethereum suffer from a bad reputation, because many of them were openly! The last category is marketplaces. There are only a few marketplaces on Ethereum, but one that is making a lot of noise at the moment is the market place of Decentraland , a virtual reality world built on Ethereum.
What are you going to build? A decentralized exchange? Or maybe something completely different? In any case, keep in mind that your Dapp will benefit the most from Ethereum if it has some sort of economy where users trade assets with Ethereum tokens. Once you have made up your mind about what you want to build, you need to actually start to think of how you will build your Dapp. To build your Dapp, you will need to learn about 3 components:.
The rest of this article will introduce you these and give you tips on what are the best resources to learn them. The Ethereum protocol is at the basis of smart contracts and Dapps. You need to understand the basics of Ethereum to understand the rest of the development process on Ethereum. Start by reading the Ethereum white paper , which is a high-level description of what is Ethereum.
It was written by Vitalik Buterin, the creator of Ethereum. This is the technical specification used by developers who implement the Ethereum protocol. A lot of mathematical notations are used, and its not for the faint of heart. I had to re-read several times to understand it. Another good place to learn about Ethereum is the Ethereum research forum. In the forum, the research team of the Ethereum foundation and Vitalik Buterin regularly discuss the latest developments in the Ethereum protocol.
In your quest of understanding Ethereum, you could also read the source code of several implementations clients. You could read the code of the main clients like Geth Go or Parity Rust but these might not be the most readable. No need to know anything about the blockchain, you should just have some basic software development experience.
Whether you have already written some code for backend, web or mobile applications, it should be enough to become a blockchain developer thanks to this course.
The blockchain is all the rage these days, and there is a lot of theoretical or anticipative talk around it, but this course will help you get your hands dirty with actual code in order to build your first decentralized application. This is the kind of skill that can get you an actual job as a blockchain developer, something that is in skyrocketing demand right now.
Have you ever looked back on the nineties, thinking you would have loved to be a part of the web revolution. Well, stop dreaming: the blockchain is here and it promises to be even bigger than the web or even the mobile revolution.
It is a power-packed technology. According to job listing search engines, software engineers with blockchain skills are in higher demand than at any time in the past, and the number of positions has grown more than fivefold in the past year.
Ever since the huge bull wave of December , interest in Blockchain technology and cryptocurrencies have been soaring. Bitcoin, Ethereum and Ripple are the famous crypto currencies as well as blockchain application. In this learning path, you will learn and deploy smart contract using Blockchain Workbench offered by Microsoft Azure.
It will be very interesting to deploy smart contract model with managing different roles Owner, Appraiser, Buyer and Inspector and also able to do transactions. That has led to a significant demand and supply gap of blockchain skills.

How to combine the right tools to put together a consistent and real world pragmatic development environment. How to deploy a decentralized app to various Ethereum instances testrpc, private chain, test chain, main net. We released the first version of this course in September Back then, the latest version of Truffle was version 3, and the best Ethereum node emulator was testrpc, on the command line.
Then, in November , the Truffle team released both Truffle 4 and a new user interface for testrpc called Ganache. Those tools had a big impact on the development lifecycle, so we took this opportunity to completely rewrite and re-shoot the practical part of this course.
So all the details you needed to troubleshoot issues are now part of the content. This course is a complete introduction to decentralized application Dapp development on the Ethereum blockchain using the Solidity language and the Truffle build framework.

If that is not the case, go study some web development first, and then come back. Some articles about becoming a Blockchain developer will just throw at you some advice without even considering what do YOU want. A lot of new developers are lured to the Blockchain world because of the crazy gains of cryptocurrencies. I can understand that this is very exciting, and its great to make money, but if you rely on this alone your excitement might be short-lived.
Ideally, you should have at least another motivation. For example:. Do you want to find a job at a Blockchain company, or do you want to launch your own Blockchain project?

In your quest of understanding Ethereum, you could also read the source code of several implementations clients. You could read the code of the main clients like Geth Go or Parity Rust but these might not be the most readable.
Instead, I would recommend to checkout a Python implementation Trinity or a Javascript. For example, Bitcore is the main client of Bitcoin, and Geth and is the main client of Ethereum. Now that you know about Ethereum, you are probably curious to know how we build applications on top of it the so-called Dapps. But before being able to learn how to build Dapps, you need to learn about the tools that are required, and about smart contracts. Solc is the compiler of the Solidity programming language.
You can compile it directly from source, or more simply you can use a package in your favorite language. Web3 is a library used to communicate with Ethereum clients like Geth or Parity. Where web3 really shine is in its ability to dynamically create abstractions objects that represent a smart contract.
These smart contract objects simplify a lot the interactions with a smart contract, and you can use them as if Ethereum had implemented an API specifically for each of the functions of your smart contract. To learn about web3, checkout the official documentation , as well as my video tutorials on How to deploy a smart contract with web3 and How to call a smart contract method with web3. By the way, in you are into Python you will be happy to learn that a Python port of web3 also exist.
Oh, and make sure that you when follow a tutorial about web3 you know which version of web3 the tutorial is using: pre 1. 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. Ever since the huge bull wave of December , interest in Blockchain technology and cryptocurrencies have been soaring.
