Twitter ETH Price Oracle

Oracles need validators for their data. We decided to see if twitter posts could work as validators. So when a verified twitter account tweets the price of ethereum, we update our price oracle. We used the Flux protocol First Party Oracle (FPO) as our price oracle for ETH / USD. From there, we used make.com to send an HTTP POST request everytime a specified user tweets the price of ethereum. That HTTP post request is sent to a node.js express server we have running on Heroku which thens calls our FPO smart contract to update our oracle with the latest price from the tweet. We also have a front end in react that calls our FPO smart contract to read the latest price from our oracle and display it on a web page!
