Orcfax is a decentralized oracle service designed to publish data about real world events to the Cardano blockchain in a way that fully addresses the oracle problem which has impeded the decentralization initiative since the desire to build services on top of blockchain ledgers. The oracle feeds issued by Orcfax are used to publish accurate and independently verifiable facts about the real world by collecting and aggregating multiple primary data sources while providing full audit logs of the complete oracle process– this enables Orcfax to deliver authentic and accurate data that users can trust but verify. The Orcfax solution will initially offer currency price-pair feeds but will expand to report on myriad and diverse feed types according to market demand.

Orcfax data is made available to on-chain smart contracts in Cardano's eUTXO native format using the Cardano Open Oracle Protcol (COOP).
