Private prediction markets
On Polymarket, your bet size is public.
On PYTHIA, it isn't.

Anatomy of a bet
Same chain. Different transparency.
Both transactions below are real and read live from Avalanche Fuji right now. One reveals its amount in plain sight. The other carries only proof and ciphertext.

A PYTHIA bet
Reading from the chain…
01
Bet privately
Pick a side and an amount. Your browser encrypts the amount and proves, in zero knowledge, that you can cover it. Only ciphertext goes on-chain.
02
Odds in batches
Pool totals are published only after enough new bets arrive, so nobody can subtract two numbers to expose your stake.
03
Paid privately
When the market resolves, winners are paid from the pools through private transfers. Even the payouts stay hidden.

Honest about trust
Private from everyone watching. Not from the resolver.
In v1 the resolver holds the pool accounts and is trusted for custody and settlement. It can see every stake, and so can the eERC auditor key. We say so up front.
