Prove your raffle was fair.

Every draw is bound to a signed, chained, publicly verifiable randomness pulse. You get a certificate anyone can check — no trust required, no "just believe us."

Start a fair draw See how it works
Commit-then-reveal

You can't rig it

The entrant list is hash-committed before the winning pulse is known. The operator can't influence the outcome — mathematically.

Signed certificate

Anyone can verify

Each draw produces an Ed25519-signed certificate. Share a link; winners and auditors recompute the result independently.

Quantum-sourced

Real entropy

Draws bind to pulses from a live quantum-optical source — not a predictable PRNG. And we say exactly what the source is, honestly.

How it works

1

Commit your entrants

Paste your entrant list. It's hashed and frozen before any randomness is drawn.

2

Bind to a pulse

The draw locks to the next beacon pulse — which nobody, including us, can predict.

3

Get a certificate

Winners are derived deterministically and signed. Share the public verify link.
