🛡️ Provably Fair System

ScratchIt uses Solana transaction signatures for randomness.

How the provably fair process works

  1. You buy a ticket → Transaction sent to blockchain

  2. Solana assigns unique transaction signature (unpredictable)

  3. Signature is hashed with SHA-256

  4. Hash deterministically generates 9 symbols

  5. Matching symbols determine your prize

  6. Anyone can verify the outcome using the signature

Result: Impossible to manipulate, completely transparent, fully verifiable.
