Provably Fair
What Is Provably Fair?
Provably fair is a cryptographic method that allows users to independently verify that the outcome of every pack opening was determined fairly and was not manipulated by Unboxd or any third party. This system provides mathematical proof of fairness.
How It Works
Step 1 — Server Seed: Before each opening, our server generates a random seed and creates a SHA-256 hash of that seed. The hash is displayed to you before the opening begins, committing us to the outcome.
Step 2 — Client Seed: You provide (or we randomly generate) a client seed that is combined with the server seed to determine the outcome. This ensures neither party can predict or control the result.
Step 3 — Result: The server seed and client seed are combined using HMAC-SHA256 to produce the outcome. The result determines which item you receive from the pack.
Step 4 — Verification: After the opening, we reveal the original server seed. You can verify that the hash of the revealed seed matches the hash shown before the opening, proving the outcome was predetermined.
SHA-256 Encryption
SHA-256 (Secure Hash Algorithm 256-bit) is the same encryption standard used by banks, governments, and cryptocurrency networks worldwide. It is computationally infeasible to reverse the hash or find two different inputs that produce the same hash, guaranteeing the integrity of every opening.
Verify Your Results
Every pack opening generates a unique verification code. You can use any independent SHA-256 calculator to verify that your results were fair. We encourage all users to verify their openings regularly.
