Verifiably Fair Random Draws
Independently verifiable winning numbers for competitions and raffles. The randomness comes from a public, distributed beacon — not from us — and every result can be checked by anyone, forever.

League of Entropy
Randomness is generated collectively by independent global organisations — Cloudflare, EPFL, the University of Chile and more. No single party, including us, can predict or influence it.
Committed before it exists
Every draw locks to a future beacon round before that round’s randomness has been created anywhere in the world — and the commitment is shown to you instantly.
Check it yourself
Every input is published after the draw. Recompute any result in your own browser, or with open PHP and JavaScript scripts — no trust in our servers required.
Run a draw
Login Required
You must be logged in to generate random numbers. Create an account or log in to get started.
Every account is reviewed manually before draws can be generated, and your operator details appear in the public ledger with every draw you run.
How every draw works
1
Commit
One click locks the draw to a future Drand round and publishes the commitment — before that randomness exists anywhere.
2
Beacon
The League of Entropy emits the round. We fetch it from Cloudflare’s public relay and cross-check it on an independent relay.
3
Combine
Beacon randomness, the timestamp client seed and all draw details go through HMAC-SHA256, with rejection sampling for zero bias.
4
Reveal
Every input is published to a hash-chained public ledger. Anyone can reproduce the result, on any device, forever.
Independently verifiable — by design
We never generate the randomness ourselves. It comes from drand’s public beacon, produced by a global consortium using threshold cryptography and published on relays we don’t control. Every draw can be checked against that beacon and recomputed with standard, open cryptography. You don’t have to trust The-RNG — you can verify it.
