How can a participant check that the draw is not rigged?

On the contest verification page, a button reruns the calculation in their browser from the published data. It checks that the revealed key matches the fingerprint published before the contest, that the list has not changed since sealing, that the public value is the one of the announced drand round and that the resulting winners are the ones displayed. They can also search for their code in the sealed list.

What is drand, and what if my server cannot reach it?

drand is a public randomness service run by the League of Entropy (Cloudflare, Protocol Labs and universities) that publishes a value every 30 seconds. When the entries are sealed, the module commits to a future round. If your server cannot reach drand at draw time, you paste the value from the drand page of that round, and anyone can compare it.

Can the contest be limited to paying customers?

Yes, by disabling the form. You can also keep both routes. Depending on the country and the type of contest, a free entry route may be required or recommended: have your rules checked.

What happens if an order is cancelled?

Until the entries are sealed, moving an order to a cancelled, refunded or payment error status removes the entry, and a new payment restores it. After sealing, the list no longer changes.

Do I need to set up a cron?

No, everything can be done in a few clicks from the contest dashboard. The cron is only needed for autopilot: sealing, draw and emails without intervention, and replacement of winners who do not claim their prize in time.

Are the generated rules legally sufficient?

They are a complete 9-article template filled with your dates, prizes and company details. Rules differ from one country to another: have them reviewed, or replace them with your own text while keeping the module variables.

PrestaShop Giveaway & Contest Module 8 & 9: Verifiable Prize Draw, Purchase or Free Entry

Entries with every order, a free entry form, referral, and a prize draw any participant can recompute.

A giveaway brings traffic and orders on one condition: participants must trust the draw. This module publishes the fingerprint of a secret key before the contest opens, seals the list of entries at the end date, ties the draw to a public drand value that did not exist yet, then reveals the key. Any visitor can rerun the calculation in their browser and get the same winners. Around the draw: automatic entries with purchases, a free form with double opt-in, a referral link, generated official rules, winner emails and a prize claim form.

At a glance

Automatic entries for every paid order: 1 per order or 1 per amount spent, eligible products and categories
Free entry form with double opt-in, bot protection and disposable email blocking
Referral: personal link and bonus entries for each friend who enters

A detailed look at how PrestaShop Giveaway & Contest Module 8 & 9: Verifiable Prize Draw, Purchase or Free Entry works, why we built it the way we did, and the thinking behind the features above.

§ 01

Why a verifiable draw changes participation

In a classic giveaway, participants have to take the organizer's word for it, and a few comments about a "rigged contest" are enough to put others off. Here, every step leaves a public trace: the key fingerprint before opening, the list fingerprint at the end date, the drand value, then the revealed key. The verification page redoes the whole calculation in the visitor's browser without sending anything to the shop, and each participant can find their code in the sealed list.

§ 02

With a purchase, without a purchase, or both

Purchase mode rewards orders placed during the contest and raises the cart value with the message "add €12 to get one more entry". The free form opens the contest to everyone and lets you offer a no-purchase-necessary route when required. Both routes combine, with a shared cap per email address.

§ 03

Fewer fake entries

Double opt-in rules out invented addresses. The disposable email list blocks Yopmail, Mailinator and about sixty other services. A honeypot field and a timed signature stop bots, and a single connection cannot send more than 5 entries per hour. A referral only counts once the friend's entry is confirmed.

§ 04

Official rules and prize delivery, without spreadsheets

The rules are generated from the dates, prizes, entry methods and your company details, then published on their own printable page. They are a template to have checked against the law of each country where the contest is open. After the draw, winners accept their prize and give their address in a form. The organizer receives an email, and the dashboard shows who replied, who is pending and who missed the deadline.

§ 05

A contest that runs by itself

With autopilot and a cron URL, there is nothing to do after launch: sealing at the end date, draw on the announced date with the drand value, winner emails, then replacement by the next reserve if a winner does not reply in time. The home page widget and the product page banner promote the contest for its whole duration.
