How it works

Online raffle with Stripe, optional technical proof and transparent math

RealisticRNG Raffle was created for people who need a simple, fast and really trustworthy raffle. On this page, you’ll understand in clear English what happens behind the “Start raffle” button and how the usage model works (free, paid and when you may want to generate the technical proof).

What is RealisticRNG Raffle?

It’s an online raffle tool that combines practicality (paste the list, click, see the result) with a level of transparency that common randomizers don’t offer.

Instead of just showing a random name on the screen, the system can generate an optional technical proof with verifiable hashes, which you can create whenever you need extra transparency for a given raffle.

Main characteristics

  • Online raffle, directly in the browser.
  • Up to 20 names for free, with no automatic proof.
  • Optional technical proof that you generate only when you want it.
  • Stripe unlock for larger lists, keeping the same proof mechanism available.
  • Names are not sent to the server; the list stays in your browser.
  • RealisticRNG technology inspired by deterministic and verifiable methods.

How to use it in practice

  1. Paste or import your participant list (TXT, CSV or Excel sheet).
  2. Review the names. The system warns you if there are duplicate names.
  3. If the list has up to 20 participants, the raffle is unlocked for free, without automatically generating the technical proof.
  4. After a free raffle, if you want extra transparency, you can optionally click “Generate Audit Receipt (RealisticRNG)” to create a technical proof for that specific draw.
  5. If there are more than 20 names, the system will ask for payment of US$ 1.00 via Stripe to unlock the raffle. Once payment is confirmed, you can run the raffle and also generate the technical proof if you wish.
  6. The idea is simple: you solve the “I need to run a raffle now” problem, and you only generate the technical proof when it makes sense for your audience, clients or audits.

The goal is to solve a real problem: “I need to run a raffle now, with security, transparency and something I can show to participants or clients when necessary”.

What makes the raffle auditable?

Whenever you decide to generate the technical proof, the system creates a record containing:

  • Raffle ID (unique RealisticRNG code).
  • Date and time of the raffle.
  • Number of participants and the selected name.
  • hash_list: a SHA-256 hash of the normalized name list.
  • hash_raffle: a hash that combines the list, the winner and the timestamp.

With this information, it’s possible to verify whether the list was altered afterwards or if the displayed result matches what was actually raffled, increasing trust for participants, customers and independent audits.
