Unsigned Proof

Unsigned proof is a proof which has no digital signature.

Unsigned proof is the proof used for cases in which the users are naturally incentivized to provide the correct input. This is usually used for game scenarios where the user will receive rewards for solving the answers to some sort of puzzles. In this flow, the user would use the answer as the input to the proof function.

The oracle service is not needed to generate the unsigned proof. This is a simpler model to implement, plus it requires less processing on the proof function.
