Raffles nobody can rig
The winner is decided by a quantum measurement committed before your list exists, mixed with a public beacon nobody can predict. Every draw ships a proof you can check yourself.
Create a draw
Your list is locked with a hash before the randomness exists. Nobody — including us — can know the result in advance.
How it works
Four steps, all of them checkable by a stranger.
Quantum entropy, harvested ahead
We put qubits on IBM hardware into superposition and measure them. The results are split into pulses and sealed under a Merkle root published before any draw exists.
Your list gets committed
When you create a draw we hash the list, the winner count and the exact future pulse it will use. Changing anything afterwards breaks the hash.
A beacon nobody controls
The seed also mixes in a future drand round. It does not exist yet when you commit, so not even we can pick a pulse that suits us.
Anyone can recompute it
Given the proof, the shuffle is deterministic. Our verifier runs in your browser and fetches the beacon straight from drand — never through our servers.
The Bell test
Every pool ships a CHSH test run in the same job that harvested the entropy. Well-spread numbers prove nothing on their own — a classical generator makes those too. This is the measurement a classical generator cannot fake.
