Fairness without gimmicks. Transparency without exaggeration.
At Jambala, trust comes from letting you verify the result yourself — not from borrowed credibility. Here is exactly how our draws work, in plain English.
How are winners chosen?
Every winning ticket is selected using a public randomness beacon called drand, combined with SHA-256 hashing. drand is run by a coalition of independent organisations (the League of Entropy) and publishes a fresh, signed random value every few seconds — nobody, including us, can predict or influence it.
The exact drand round that seeds a draw is fixed by the competition's published close time, so we are committed to it before entries close. When that round is produced, we combine its randomness with the published list of entered tickets to select the winner.
For each draw we publish:
- drand roundthe beacon round committed to the draw time
- randomnessthe signed random value for that round
- ticket pool + hashevery entered ticket, and its SHA-256 fingerprint
- winning ticketthe number the algorithm produces
You can re-run the same maths on any computer and confirm the winning ticket is the only possible result. See How We Draw to reproduce any draw yourself, right in your browser.
Two formats of draw
Automated
A script runs at the scheduled draw time, seeds from the committed drand round, and immediately publishes the full proof record to the verification page.
Live
The draw is conducted openly during a livestream so you can watch the winning ticket being selected in real time. The result is recorded on the same public page.
In both cases the inputs and outputs are recorded publicly and the result is independently reproducible. Prizes are awarded in accordance with the laws of chance.
Are your draws certified or casino-grade?
No — and we are intentionally clear about that. Our competitions are prize competitions, not regulated gambling products, and we do not use gambling-style compliance language to imply otherwise. Instead of borrowing a certification, we publish the full proof of every draw so you don't have to take our word for anything.
Why drand?
Public and unpredictable. drand's randomness is produced jointly by many independent organisations. Nobody can predict a future value, and nobody — including Jambala — can change it after the fact.
Independently verifiable. Every round is signed and served identically by multiple public mirrors. Anyone can fetch the round, check the signature, and re-run our published algorithm to confirm the winner.
Committed in advance. Because the round is tied to the published close time, we can't shop for a result we like — the seed doesn't even exist until entries have closed.
