Verifiable Fairness

How we guarantee fairness in every draw

Distributed Generation

The League of Entropy, a global network of independent organisations, generates randomness using threshold cryptography. No single party can control the output.

Public Beacon

The generated randomness is broadcast publicly as a Drand Round. This beacon is verifiable by anyone, anywhere, ensuring the source is immutable.

Client Seed

We combine this public randomness with your unique Client Seed (timestamp) using HMAC-SHA256. This ensures the result is unique to your specific draw.

Public Verification

You can verify the result yourself using the public Drand round, your Client Seed, and our open-source verification tools. Verify Past Draws →
