Gotts-Oracle is a Price Feed Oracle. It will include the following features:

• Local REST API interface for price query of all necessary pairs of Foreign Exchange Market.
• Real time price, and the result is the median value among at least 3 data vendors.
• And for cryptocurrencies price, real time price is the median value from at least 5 exchanges.

For the moment, only one data vendor is provided: https://www.alphavantage.co/. But indeed we need more.
