The oracle_votes table is used during unwrapping operations. The registered oracles will call unwraptokens and either emplace a new record or modify the record if the oracle is not the first registered oracle to vote on the obt_it. Once an oracle calls this action and 100% consensus is reached, the unwrapping will be approved and funds will be transferred.
