# Transparency

* **Open-source code**: Anyone can audit contracts.
* **Verifiable randomness**: Switchboard VRF ensures cryptographic fairness.
* **On-chain proof**: Every transaction and selection is visible.

What is VRF?

* Randomness generation: A VRF takes some input (like a block hash or timestamp) and runs it through a cryptographic function to produce a random number.
* Proof of fairness: Along with the random number, the VRF also outputs a proof. Anyone on-chain can check this proof to confirm the number really came from the original inputs and wasn’t tampered with.
* Immunity to bias: No one — not even the project team — can predict or influence the outcome once the inputs are locked.
* On-chain transparency: The proof and result are stored on the blockchain, so participants can independently confirm the selection process was legitimate.

Think of it like a digital lottery machine that prints a receipt showing exactly how the winning number was chosen — and lets anyone check that the draw wasn’t rigged.
