I have an auction contract, where bidders bid with Ether then me (owner) select which offer is most suitable and thus this bidder is contract winner.
Once the winner is selected, I send him data as a reward. This data is sent off-chain.
Trying to think of a way to add privacy to my system, in terms of keeping bidders identity anonymous or the identity of the winner?
Is it possible that once contract is closed, when bidders withdraw their funds that amount is not kept public as well?
