is virtual prediction market a thin in FHE and zama ?
I built BLACKBOX on Zama
it is a fully encrypted prediction market where your position is never exposed on-chain.
every prediction market today has the same problem: your bet is public.
people can see what you predicted, how much you committed, and exactly when you entered. that information can be used against you.
BLACKBOX changes that with Fully Homomorphic Encryption (FHE).
here’s what happens:
• your prediction and stake are encrypted in your browser before they’re sent on-chain.
• the smart contract only receives encrypted data.
• settlement happens directly on that encrypted data, nothing needs to be decrypted.
• once the market resolves, only you can decrypt and view your result.
under the hood, BLACKBOX uses commit-reveal randomness for verifiable outcomes and fixed odds to work around encrypted arithmetic limitations, while keeping sensitive user data private.
what stays private:
your prediction
your stake
your settlement result
what stays public:
• market creation
• market deadlines
• published odds
• final outcome
• participation
this is not just about privacy, It’s about removing the information advantage that comes from watching everyone else’s positions.
BLACKBOX is a glimpse of what becomes possible when smart contracts compute on encrypted data instead of exposing everything by default.
