Abstract

TraceIt aims to revolutionize Poultry Market using Ethereum blockchain which provides transparent, secure data storage and transfer technology with no intermediary.

How To Setup Our Application

1. Install Metamask

MetaMask : An Ethereum Wallet in your Browser

To connect your web3 js to the locally hosted truffle development we need metmask. You can download its Chrome Extension At MetaMask Chrome Extension.

Other Browser Users can find MetaMask Extension/AddOn On their respective browser stores.

After installing click on add new network and set your new network to localhost:3000 And also Add the account key to the first account that is account[0] with the respective secret key.

Note: Every time you start from fresh always remember to reset your metmask acount as your localhost starts from zero but the metmask always stores some cached data therefore it will thow error as the nonce would not match.
