How IVAWIN Works

Simple version

1. Choose a competition.
2. Read the prize details, draw date, entry price, maximum entries and free-entry route.
3. Enter online or use the free-entry route if available.
4. Your confirmed entries receive ticket/entry numbers.
5. The competition closes at the stated time or when sold out if configured that way.
6. IVAWIN runs the draw using the published draw process.
7. The winner is verified and contacted.
8. Draw information is published so users can check the result.

Why IVAWIN is different

IVAWIN is designed to support a provably fair draw model. Instead of simply asking users to trust an internal draw, the system can publish evidence that the winning number could not be chosen after the entries are known.

Plain-English draw fairness explanation

Step 1 — Commitment before the draw

When a competition is created, IVAWIN generates a secret value called a server seed. The secret itself is not published immediately. Instead, IVAWIN publishes a cryptographic hash of it. Think of this as sealing the secret in a transparent envelope: users can later check that the secret was not swapped.

Step 2 — Entries are recorded

Paid and accepted free entries are recorded against the competition. Confirmed ticket/entry numbers are visible in the user's account and/or confirmation email.

Step 3 — Independent randomness

At draw time, IVAWIN uses an approved randomness source/process. The intended design uses NIST randomness or a documented fallback where required.

Step 4 — Winner calculation

The random value and the fixed entry list are used to calculate the winning entry.

Step 5 — Reveal and verify

After the draw, IVAWIN reveals the original server seed. Users can check that the revealed seed matches the hash published earlier and that the winning number follows the published method.

What users should see

Each completed draw should show, where available:

• competition ID
• closing timestamp
• total eligible entries
• published hash/commitment
• randomness source/value
• revealed server seed
• winning number
• winner status
• verification result
