Why learn Developing Blockchain Applications

There are currently 14 open jobs for every blockchain developer, making it one of the most in demand skills in the tech industry (TechCrunch). We call that an opportunity. The ability to develop decentralised apps on the Ethereum platform is an incredible advantage for job seekers in the blockchain space. Gartner predicts that by 2025 the business value-add of blockchain will grow to around $176 billion.

How does it work

Developing Blockchain Applications is a hands-on programming course that deep dives into the largest, most widely used blockchain platform – Ethereum. You will learn to use core Ethereum development tools including Solidity, web3.js and Embark. You’ll start by building a simple TODO list DApp before moving onto your project. We’ll cover best-practice for testing smart contracts, interacting with decentralised services and libraries (e.g. IPFS), designing your DApp user experience, optimising for efficient transactions and understand some of the ethical and security issues a DApp developer must consider.

In the end you will tie it all together and build a real decentralised app under the guidance of industry experts.

Skills learned

DApp development on Ethereum, programming smart contracts with Solidity, testing with web3.js, building interactive DApp interfaces, managing access and permissions, data storage with IPFS, managing and updating smart contracts in an immutable environment, testing best practice, UX considerations for DApps, efficient use of gas, using external libraries, ethical considerations, security in smart contracts
