# Decentralized application(Dapp) with OST platform * Project demo for ISOM3000B Blockchain Entrepreneurship for Social Impact * Simple prototype with limited amount of features

Client	Java
Server	Go
Database	MongoDB
Smart Contract	Solidity

Project Description:

• Branded token (the cryptocurrency wallet system) provided by OST platform
• Ethereum Smart Contract, which provides permanent and immutable storage for charity project information
• Whenever a new project is submitted to the contract, a server built with Golang will automatically upload the project details to MongoDB for ease of access
• Client side built with Java displays all the available projects in the database and users can donate cryptocurrency to those projects by purchasing branded token from the platform
• Charity can upload prove of progress to ipfs (blockcahin file storage), and the hash will be storage in the smart contract for reference.
• User can download the prove in the client, and verify the project progress

>Data flow and storage

>Demo video showing the prototype, which illustrates the user interaction using a mockup(UI) alongside with the implementated application. >Since the prototype has to be done in less than 3 weeks time, the java implementation has a relatively simple and unfinish interface.
