How to Verify a Coinflip Round

You can re-derive any Rust Snowball coinflip outcome from the published server seed, client seed, and nonce — in 30 seconds via the provably-fair page or via the open-source @rustsnowball/provably-fair package.

Step-by-step

Open the coinflip round in your history → click "Verify".
The page shows: server seed (revealed), client seed, nonce. All three are needed.
Either click "Verify in browser" (instant), or paste the three values into the global verifier at /provably-fair.
The verifier shows the derived outcome. If it matches the round's outcome, the round is fair.

Detail

For paranoia-level verification, install @rustsnowball/provably-fair locally and re-derive yourself. The library is open source on GitHub.
