Roadmap to Becoming a Web Developer in Web and blockchain technology are transforming the internet and opening up new developer opportunities As decentralized applications and blockchain based platforms grow in popularity there is increasing demand for developers with Web skills This article provides a roadmap for aspiring web developers on how to get started in What is Web Web refers to the next evolution of the internet based on blockchain technology It aims to create a more open decentralized web where users own their data and applications are not controlled by a centralized entity Some of the key components of Web include Cryptocurrencies and digital assets like Bitcoin and Ethereum Decentralized applications dApps built on blockchain networks Decentralized finance DeFi protocols and services Non fungible tokens NFTs for digital ownership Decentralized autonomous organizations DAOs Why Become a Web Developer Here are some of the key reasons to consider becoming a web developer Huge growth and opportunities in web space Work on cutting edge blockchain based products and services Be part of shaping the future of the internet A lucrative career with high demand and competitive salaries Flexibility to work remotely or be part of decentralized teams Chance to innovate without centralized control or censorshipLearn Blockchain BasicsThe first step is to understand the basic concepts of blockchain technology How public private key cryptography works Hash functions and cryptographic security Distributed ledger technology and consensus mechanisms Smart contracts and how they execute on the blockchainLearn the basics through online courses tutorials books and blockchain communities Having a solid base will help tremendously when starting to code Pick a Platform to Specialize InThere are several leading smart contract development platforms to choose from The most popular options are Ethereum The second biggest cryptocurrency platform after Bitcoin with its own blockchain and smart contract functionality through Solidity Solana A high speed blockchain focused on scalability and throughput for dApps Programming is done in Rust Polkadot A multi chain network that allows different blockchains to interconnect Offers support for Substrate and other frameworks NEAR Protocol Developer friendly blockchain built for performance and usability Supports development in Rust and AssemblyScript Pick one platform to start with based on your interests and existing coding background Focus on becoming proficient in developing the platform s tech stack Learn a Blockchain Coding LanguageIt s time to learn a coding language for writing smart contracts and dApps Here are the top options Solidity The most popular language for writing Ethereum smart contracts Similar syntax to JavaScript Smart contracts are programs that run on the blockchain They are pieces of code that encapsulate business logic and execute when certain conditions are met Some key features of smart contracts They reside on the blockchain network and run exactly as programmed without any possibility of censorship downtime or third party interference They are immutable once deployed the code cannot be changed They can hold and transfer assets digitally through code e g cryptocurrencies NFTs etc They use public key cryptography to prove identity and authorize transactions Transactions are trackable on the public ledger Smart contracts can interact with other contracts to compound functionality Gas fees are required to deploy and execute them on the blockchain Smart contracts allow for decentralized applications like finance games voting systems governance etc without needing a centralized intermediary Developers write smart contract code in languages like Solidity and deploy them to blockchain networks like Ethereum Users can then interact with the deployed contract through transactions to execute the logic Now that we ve covered the basics of smart contracts let s look at an example Solidity smart contract to see how to write and deploy one SPDX License Identifier MITpragma solidity contract SimpleStorage uint storedData function set uint x public storedData x function get public view returns uint return storedData First make sure to use Remix an online code editor for developing solidity code You can get started here This contract allows storing a single unsigned integer variable It has two functions set Allows updating the stored value Uses the public keyword to make the function callable from outside the contract get Returns the stored value view keyword means it does not modify state only reads To use this contract Compile it with the Solidity compiler solc This generates bytecode that the EVM can understand Deploy it to the blockchain using web js ether js or a framework like Hardhat This deploys it to a specific network Interact with the contract functions to store and retrieve data For example Set the value to await contract set Get the stored value const x await contract get x After compiling your code you can deploy to see the output here Key things to note Functions need to be declared as public or external to be called externally State variables like storedData persist between function calls view functions only read the state while non view can modify it This is a very simple example but shows the basics of writing and using a Solidity smart contract Let me know if you need any clarification or have additional questions Rust Used for Solana NEAR and Polkadot development Provides great speed and security AssemblyScript TypeScript like language used for writing NEAR smart contracts Easy for JavaScript developers Substrate Polkadot s custom framework has coding languages like Ink and others Spend adequate time learning the language basics and practicing with sample code and scripts Focus on understanding concepts like states functions gas fees etc Explore dApp FrameworksSeveral JavaScript based frameworks make it easier to build complete decentralized applications Ethereum MetaMask Truffle Hardhat Web js Solana Anchor Solana Web NEAR NEAR SDKLearning these frameworks lets you connect your blockchain to a front end UI and external interfaces Start Building Simple ProjectsOnce you have the basics down start testing your skills by building simple dApps end to end Deploy a basic smart contract on Remix or another IDE Develop a simple blockchain transaction interface Write scripts to interact with your contract Connect to a frontend like a React app List your app idea on blockchain freelancing sites to get experienceStarting with simple projects will help reinforce what you ve learned and gain real world experience Become Part of the CommunityEngage with other Web developers on platforms like Twitter and GitHub Follow leading developers in the space Join Discord channels to ask questions and get help Attend local blockchain meetups and hackathons This will accelerate your learning and open new opportunities Here are ten top communities to join to get started Ethereum Developer Community The largest community of Ethereum developers Great for learning Solidity Web development and working on Ethereum based projects Solana Developer Community Connect with developers building fast and scalable apps on the Solana blockchain Learn about projects on Solana and developing with Rust Polygon Developer Community Polygon provides scaling solutions for Ethereum Join to work on Polygon SDK Plasma chains zkRollups etc Polkadot Developer Community Official community forum to discuss Substrate PolkadotJS and building cross chain dApps NEAR Protocol Developer Community NEAR developers share learnings on building with Rust AssemblyScript NEAR SDK and Nightshade sharding Chainlink Developer Community Building Oracle networks and connected smart contracts using Chainlink IPFS Developer Community Decentralized storage community discussing libpp Filecoin and using IPFS in dApps Starkware Developer Community Developers of STARK based ZK rollup scaling solution for blockchains like Ethereum Arweave Developer Community The Permaweb community focused on building censorship resistant dApps on the Arweave blockchain CryptoDevs Active Discord community for all things crypto and web development Joining these communities allows you to connect with experienced blockchain developers collaborate on projects and accelerate learning Never Stop LearningWeb is rapidly evolving so you must constantly learn about new developments frameworks dApps and innovations in the space Sign up for newsletters read tech blogs listen to Web podcasts and take advanced courses to upgrade your skills Apply for JobsOnce you are at this point and you want to start connecting with a protocol start applying You literally find blockchain developer job boards everywhere Here are some examples Reddit CryptoJobsList GitCoin WeekInEthNews CryptocurrencyJobsAnd so much more…Or you can contact protocols you like and see if they are hiring Freelance for GrantsDecentralized protocols have treasuries that are dying for work to make them better If you have an idea for a protocol apply for a grant One of the best places to find grants out “in the wild is on gitcoin but often protocols will have grant programs as well Ethereum Grants Chainlink Grants Solana Grants Uniswap GrantsConclusionBecoming a proficient web developer takes time commitment and hands on practice However the opportunities in the space make it a rewarding career path for developers who want to build the decentralized future of the internet Follow the roadmap outlined here to get started on your Web journey today If you find this post exciting find more exciting posts on Learnhub
