⚡ Bitcoin-Only. Provably Fair. Verified by Math.
Every 21Stacker draw uses the same cryptographic standard that secures Bitcoin — SHA-256.
We pre-commit a secret hash before entries open, then combine it with a future Bitcoin block hash to calculate the winner.
🧱 Transparent. Trustless. Impossible to fake.
This is what provably fair looks like.
🎯 Answer the question.
⚡ Pay in sats.
🏆 Win Bitcoin.
