How To Become a Blockchain Developer: Step-by-Step Plan
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.
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. If you are looking for online courses for learning to build Ethereum Dapp, you can check out the below links:. If you reach this step you would have accomplished a lot in your quest to become a Blockchain developer and find a job at Blockchain company.
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. Every digital record in the thread is referred to as a block. It allows either an open set or limited set of users to participate in the ledger, with each block linked to a certain participant. It may only be updated by consensus between the participants in the system and data can never be erased once it is entered.
Bitcoin is the most well-known use of blockchain technology so far. It is a cryptocurrency that allows financial transactions over an open network with encryption and digital bits. Anything that is digital can be copied multiple times. The challenge with implementing a digital payment system is to ensure that no one spends the same money twice. Usually, this is accomplished by having a trusted authority such as Paypal verify financial transactions.
What makes Bitcoin so exciting is that it uses consensus in a truly massive peer to peer network to verify financial transactions.
The result: Payments are non-reversible, accounts can never be frozen, and transaction fees are lower. Some users use their computers to verify transactions in the peer to peer network we describe above. These users are rewarded with new Bitcoins proportional to the amount of computing power they gave to the network.
If you can develop blockchain developer skills, you can become wealthy in many cases. These are full time workers at major corporations. Blockchain developers and engineers are finding demand in high paying work for even classic financial sector companies, such as Bank of America and Visa. As blockchain grows and becomes more accepted across the international financial world, it is very likely demand in this field will only grow in the next decade.
That is why forward-thinking techies should be learning the new skills needed to be a blockchain developer. This article will provide you with the basics on how to become a blockchain developer and how to continue to grow your skills as this new technology grows and changes every year.
The top blockchain platforms today are bitcoin and ethereum. Most applications are built on one of these. There are other blockchains being developed that are not as popular yet. Bitcoin and ethereum are pubic blockchains, meaning that all users and applications are sharing the entire ledger. Meanwhile, other blockchains, such as Hyperledger, offer permissioned and private blockchains for a certain number of authorized users.
This field is all about computer science , so if you want to become a developer, be ready to learn a lot of programming. See also best things to do with a computer science degree.
Different blockchains and coins are built with various computer languages. Some blockchain technologies are trying to expand their appeal by supporting other languages, too. You will have many options at your disposal as far as learning computer languages, but you will have to grow your skills in many of these languages to become a developer. Also, you will need advanced web development skills. There is a ton of back-end programming necessary for blockchain development.
You also should have cybersecurity and computer network skills; blockchain developers need to collaborate with professionals from these fields. Now that you understand some of the programming you need to learn, now you can see some examples of blockchain in action below.
It also includes an explanation of how the Interledger Protocol facilitates payments across different payment networks. So what exactly do you do as a programmer for blockchain? Below are some simple examples from Youtube about how to build blockchain and related examples.
These are quick video examples, but provide good insight into what you will be working on. Most professionals who want to add blockchain programming to their skills already are adept with Java and Python, but this is not a requirement. More universities are introducing new curricula that will teach students about blockchain technology.
The online education startup called B9lab recently launched an online Certified Ethereum Developer Training program, as well. The company reports its most successful students tend to have sysadmin experience and know Javascript , but people without a technical background have learned the necessary coding skills, as well.
The most important thing to get a job in this booming tech field is to nail down all of the computer skills highlighted earlier in this article. No matter how much demand there is for developers for blockchain, you have to have all of the fundamental programming skills nailed.
Some of these business applications will probably include these:.

Major crypto firm expects Polkadot (DOT) to become a top 3 blockchain
He stated :. Ethereum has been by far the most dominant smart contracts blockchain protocol to date. Polkadot does not directly compete against Ethereum, and as Koh explained, the long-term prosperity of DOT should not result in a decline of Ethereum.
Blockchains, like Polkadot and Cosmos, which enable multiple blockchain networks to exist on their protocols, are structurally different from Ethereum.
Koh explained :. Polkadot and Cosmos will not replace Ethereum. If Polkadot, along with other smart contracts protocols, can co-exist with Ethereum, it raises the chances for long-term survivability. Major exchanges have already listed DOT after its major denomination change, showing support for the cryptocurrency.

Blockchain developer is one of the highest-paid jobs in the software industry. The demand for blockchain engineers has increased by percent since This article covers a few common blockchain developer questions such as: How do I become a blockchain developer? What skills do I need to become a blockchain developer?
Where do I start? In simplified terms, blockchain is a secure, shared, distributed ledger. That means the data stored on a blockchain is secure using cryptographic algorithms, shared among multiple contributors and participants, and distributed on a peer-to-peer network among multiple nodes. Each participating node has a full copy of the code and database. Blockchain is expected to become a major component of Web 3. Not only are blockchain developers in high demand but they are also getting paid more.
Blockchain creators need to understand several underlying technologies of blockchain including low-level programming, network programming, understanding of cryptographic algorithms, mathematical consensus algorithms, database technologies, decentralization, console development, and high-level expertise in code debugging, testing, and performance optimization. This kind of job is usually performed by software engineers and low-level programmers. There are a limited number of jobs in this area.
The blockchain ecosystem is more than just a blockchain project. The blockchain company also needs general-purpose software developers, websites, and databases. In the cryptocurrency space, wallets are popular.
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:. If you reach this step you would have accomplished a lot in your quest to become a Blockchain developer and find a job at Blockchain company.
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. A great way to do this is to go to Ethereum meetups and conferences. For meetups, you can go to meetup to find Ethereum and Blockchain meetups in your region. Make sure you pick a meetup that is focused on the tech, as many are focused on the business side of things and tend to try to sell you their latest ICO-investment crap.
As for conferences, the most famous one for Ethereum is DevCon a bit pricy though. These are way cheaper than DevCon and less crowded. Finally, if you want to keep updated with the latest news of the Ethereum ecosystem, you can consult these resources:.
