CosmicPump is provably fair. Every game's outcome is locked in by cryptography before you play, and you can independently verify it afterwards — no one, not even us, can change a result once it's committed.
Before each round we generate a secret server seed and publish its SHA-256 hash. The hash proves the seed exists without revealing it — locking the outcome in advance.
Crash folds in a live drand beacon (public randomness fetched in real time, so we can't pre-compute). It mixes with your own client seed via HMAC-SHA256.
After the round, the server seed is revealed. Re-hash it yourself — it must match the hash we committed earlier, proving nothing changed.
Run the open-source algorithm with the revealed seed (plus your client seed and the drand value) to reproduce the exact outcome you saw.
Currently, CosmicPump Crash uses our standard drand-backed provably fair algorithm. More games will be listed here as they are added to the platform.
