# Why Verifiable Onchain Randomness?

> Verifiable randomness ensures that random outcomes in decentralized applications are **fair, transparent, and tamper-proof**

**Traditional offchain randomness** suffers from:

* **Lack of transparency** – Users cannot verify how random numbers are generated.
* **Manipulation risks** – Developers, miners, or validators could influence outcomes for financial gain.
* **Delayed or unreliable delivery** – offchain randomness may not align with onchain execution timing.

**Verifiable onchain randomness** solves these challenges by providing:

* ✅ **Cryptographic verification** – Randomness results are proven and validated onchain.
* ✅ **Fairness and trustlessness** – No single party can manipulate outcomes.
* ✅ **Full transparency** – Every random value can be audited directly on the blockchain.
* ✅ **Instant availability** – Randomness is delivered onchain within seconds, ready for use in smart contracts.
