An Ethereum smart contract and website interface for incentivized requesting/distributing of content. Smart contracts are used to show users proof-of-interest in requested content, and a refunded deposit incentivizes requesters/backers to validate submitted content. IPFS's content-based addressing ensures that there is no tampering of the distributed content after its upload. It also includes a new ERC-721 compliant non-fungible token, called Flags, which are distributed to users upon transactons with the EtherBay Dapp and are identified by their unique ID and corresponding flag image (which is rendered in an HTML canvas).

Dependencies:

• npm
• ipfs-mini
• BigNumber
• ipfs
• truffle

Creating Ethereum Environment This project is developed using the Truffle framework. To build the smart contracts, run truffle compile. Then to instantiate a fake blockchain+network, execute truffle develop. This will launch a prompt where the command migrate can be entered to deploy the compiled EtherBay contract to the test blockchain.

Setup IPFS Since we are the webserver, we should be the ones running the IPFS gateway that we query. Follow instructions here to install an ipfs gateway peer. The result should be a daemon ipfs gateway with an API port open on port 5001.

Run the Webserver To run the webserver on port 8080, in a separate console run npm run dev.
