Off-chain computation via Oracle

On chain computation is sometimes too expensive for critical data. One possible solution is to outsource the computation off-chain, like with the help of an external Oracle system. There might be two solutions for such an off-chain computation: 
-  with the help of a trusted external Oracle: of course the problem is that the off-chain actor has to be trusted. 
- with the help of decentralized Oracle system: here several independent off-chain actor would compute the result and they are incentivized with like game theoretical tokenization that produce the correct result.
