IIT D - COL 867 - Assignment: An Ethereum smart contract for licensed media distribution.

Media.sol

An Ethereum smart contract for licensed media distribution.

Stack

• Solidity for the core smart contract code.
• Ganache to run a local Ethereum testnet. I used the GUI, but ganache-cli will work as well.
• Truffle to manage the dev environment - compile contract, interact with local testnet and run tests.
• Solium to lint the contract for style and security best practices.
• Mocha & Chai for writing unit tests.
• ES Lint for linting the JS tests.
• General HTML/CSS (Bootstrap)/JS for the Web UI.
• MetaMask as the bridge between the browser and the dapp?

Building

git clone https://github.com/dufferzafar/solid-media
cd solid-media

# Run Ganache!
