Challenge Archive

The archive exists because every past week is still verifiable

Each completed challenge keeps its revealed server seed, its client seed, its full leaderboard, and its winner. Anyone can re-derive every entry’s outcomes from those public values. That’s the entire point of provably-fair: time-travelable trust.

If a past winner’s submission can’t be reproduced from the seed, it’s invalidated. If multiple winners cluster around a non-reproducible outcome, the challenge is invalidated. The archive is a permanent record because it’s a permanent audit target.

Why we link to past entries

Beyond the audit trail, past entries are strategy material. Look at how the top three players sized their bets across a specific Crash week. The same sequence rewards very different approaches — comparing their reasoning is the best free strategy education you can get.

Future feature: a “compare entries” view that shows two players’ bet sequences side-by-side across the same outcomes. Watch where their decisions diverged and what each decision cost.

Verifying a past winner yourself

1. Open a past challenge page; copy server seed + client seed.
2. Open the PF Universal Verifier and paste both.
3. Step through nonces 0 to (winner’s bet count − 1), recording the multiplier at each.
4. Multiply the submitted bet sizes by those multipliers, applying losses and wins as the player would. Final bankroll must match within rounding error.

This is tedious but deterministic. Anyone with a verifier can do it. The whole leaderboard is publicly falsifiable.
