A decentralized game based on CelebrityBucks and powered by Tellor.io oracle playground.
Tellor Encode Club Hack 2nd Prize Winner 🏆
Tellor is a decentralized oracle network putting real world data on-chain.
The challenge was to use Tellor Playground and build a project that uses data types Tellor doesn't currently support.
CelebrityBucks.com assigns dollar values to every mention which allows them to provide a view into both who and what celebrity the world is talking about. But who commands the highest price? It is game time: tap on the more monetisable celebrity's image, or tap "same price" if world is talking about them equally.
A game is a cool showcase using Tellor oracle playground to check the right or wrong selection at each round.
Built with love for Tellor challenge at Encode Club Hack.

npm install --save-dev @nomiclabs/hardhat-ethers ethers @nomiclabs/hardhat-waffle ethereum-waffle chai
The Celebrity.sol contract is using Tellor to read the celebs price from the Celebrity Bucks data and images cached and transformed locally following the terms of use of the endpoint. More info
To compile the contract, please run the following commands:
npm i usingtellor
npx hardhat compile
Finally, the Celebrity contract has been deployed to the Ropsten testnet via Infura and running:
npx hardhat run scripts/deploy.js --network ropsten
The deployed contract address in Ropsten testnet is: 0x1D50e2c7286224A25295945A7B67B9398aCa64dc
The Tellor Playground aims to help anyone building on Tellor to quickly test and implement ideas and it is available on Ropsten testnet at the address: 0x20374E579832859f180536A69093A126Db1c8aE9
