Build a hello world app that connects to the XRP ledger via the Xpl JavaScript SDK, retrieves the last validated ledger index, and prints it.
Install the latest node.js and npm, set up a code editor (Visual Studio Code recommended), and optionally git. Note Mac, Windows, and Linux differences for your environment.
Learn how to set up a development environment for blockchain development, including node with npm, VS Code, and git, and optimize coding quality with spell checker, ESLint, and Prettier.
Trace the history of blockchain from the 2009 first public blockchain and bitcoin paper to the rise of smart contracts, cryptography, and Ethereum, XRP, with evolving regulatory clarity.
Explore what blockchain is and why trust stems from secure, decentralized design. Trace history from satoshi's white paper to smart contracts, and examine hashing, consensus, and immutability, with xrpl focus.
Trace the XRP ledger's history from its 2012 launch to a decentralized, energy-efficient blockchain designed for fast and efficient payments.
Explore the XRP ledger features, including fast payments with finality, issued assets and NFTs, plus key functions like payment channels, escrow, trust lines, and the decentralized exchange.
Explore the XRP ledger development community, a vibrant ecosystem of resources for developers. Engage on discord, blogs, twitter, and events like apex and hackathons for funding and opportunities.
Explore the XRP ledger explorer and inspect a mainnet ledger, then switch networks and set up a testnet account with activation and keys, then send and verify a testnet payment.
Configure ESLint, Prettier, Bootstrap, and Sass for a React app, featuring a custom React plugin config, node globals, and disabled prop types and React import checks.
Import real testnet accounts by pasting a family seed, derive the address with the SDK wallet, and store it in a context with local storage for persistent account management.
Create a new send page to transmit XRP, wire routes, and build a form for amount, destination, and optional destination tag. Include a spinner and automatic balance refresh after sending.
Prepare a Ubuntu Linux server with root access, upgrade all packages, and open ports 22, 80, 443, and 51235, then point DNS to the server for rippled setup.
Configure rippled for WebSocket access via nginx proxy, adjust the ledger history setting, and expose a public WebSocket using port 443 with Letsencrypt certificates; test with Postman.
Convert your stock node into a validator to participate in consensus by creating a public/private key pair and token, configuring domain verification, and securing the rippled setup.
Learn Blockchain Development using the XRP Ledger in this course:
“The Complete XRP Ledger Developer Bootcamp” (Stage 1).
I will teach you the fundamentals of how to build on the XRP ledger from the ground up, using a combination of theory and practical coding tutorials to dive deep into the core features you must know in order to build real-world applications on the XRP ledger.
This course assumes you have no previous knowledge or experience with the XRP ledger or blockchain development, making it perfect for beginners who are eager to explore the world of blockchain programming and crypto development. You'll learn how the XRP ledger stands out among other blockchains, focusing on its unique consensus algorithm and high transaction speed.
We will start with the basics of blockchain technology. Then we will learn about the core features and concepts of the XRP ledger and get into the basics of XRP ledger development, before building a fully functional wallet using react.js. We will end stage 1 with a detailed look at XRP ledger infrastructure, including a step-by-step guide to setting up and running your own node.
By the end of this course, you'll not only have a robust theoretical understanding of the XRP ledger but also practical experience of interacting with its many diverse features.
Whether you're a developer, entrepreneur, or blockchain enthusiast, this course will equip you with the foundational knowledge and skills to confidently build on the XRP ledger.
Enrol now! and you'll be interacting with the XRP ledger (using code) in less than 15 minutes!
