Course Syllabus for Decentralized eBay Marketplace on Ethereum and IPFS

Course Syllabus for Decentralized eBay on Ethereum and IPFS

This is an intermediate level guided course where you will learn to build a decentralized marketplace similar to eBay. You will build a smart contract where any one can list their products they like to sell in the marketplace. Consumers can browse the products and purchase products. You will also implement an Escrow service which is used by buyers and sellers to protect their transactions and guarantee payment and delivery. This application will be built using the Solidity programming language using the Truffle framework, Javascript and HTML/CSS. IPFS will be used to store images and large text and MongoDB will be used as an offchain solution to implement the product search functionality. Few key libraries that will be used to build the application include web3js, ipfs-api and ethereumjs-util.
