Background and strategic fit

An Oracle is a trusted contract/program that produces a result with some reliability.  In Ethereum, Oracles watch the blockchain for events and respond to them by publishing the the results of a query back to the smart contract.  When smart contracts need to interact with the 'off-chain world', Oracles can provide these results back to the blockchain.  Oracles can be used in Trusts or Escrows.  For example, a Trust contract will hold monies until an Oracle indicates that a condition in the trust contract has been met.
