OCSA Certified Draw

20 May 2026: the DCMS Code takes effect

From 20 May 2026, DCMS expects prize draw operators to be operating fully in line and compliant with the Voluntary Code of Good Practice.

That means all operators but particularly code signatories need to move quickly from informal assurance to evidence-backed practice.

Winner selection is one of the clearest places to start.

If your draw process still depends on screenshots, screen recordings, livestreams and a basic online RNG, now is the time to upgrade.

OCSA Certified Draw gives operators a practical and affordable way to evidence the draw process before the Code takes effect.

The sector still has a choice

The DCMS Voluntary Code gives the prize draw sector an opportunity to show that it can raise standards without heavy-handed regulation.

But that opportunity will not last forever.

If operators cannot demonstrate fair, transparent and evidence-backed practice, the likely alternative is legislation written for the sector rather than with it.

OCSA’s view is simple: it is better for responsible operators to build credible standards now than wait for rules they may not like later.

If the sector does not get this right on its own, someone else will do it for us.

Still using a basic online RNG?

Basic online random number tools can generate a pseudo-random number, but they are not designed to create a full draw evidence record.

OCSA Certified Draw (OCD) is built for competition operators who want something stronger: a visible, certificate-backed draw process that can be verified afterwards.

Your audience can still watch the draw live - but now the evidence can also be verified later. Forever.

Upload. Draw. Certify.

1. Upload your entry list — the list is hashed before the draw, creating a secure fingerprint of the entries used.
2. Run the draw — the winning number is generated live using verifiable randomness.
3. Record the result — the draw evidence is written on-chain and captured in a PDF certificate.
4. Receive your certificate — the certificate is displayed, emailed and archived by OCSA.

Visible process. Verifiable result.

The winning number does not exist until the certified draw completes

OCSA Certified Draw is not a pre-selected result displayed on screen.

The draw is initiated live, verifiable randomness is requested, the result is recorded on-chain, and only then is the certificate issued.

A certified draw usually takes around 1–3 minutes because the system is creating the evidence record as the draw happens.

Request submitted. Oracle nodes generate randomness. Result written on-chain. Proof Certificate issued.Copy Certificate archived at OCSA and made public.

One certified draw. One fixed price.

OCSA Certified Draw is priced by the certified draw, not by the size of the ticket range.

The current certificate format supports ticket ranges up to 999,999,999.

A small draw and a high-volume draw cost the same to certify.

One certified draw. One fixed price. No entry-volume shock.

For technical teams

OCSA Certified Draw uses pre-draw entry-list hashing, verifiable randomness, on-chain result recording, PDF certification, email delivery and OCSA archive storage.

The completed certificate includes the draw details, winning number, hash records, chain reference and certificate record.

OCSA Certified Draw is designed to create tamper-evident draw evidence that can be checked afterwards. For eternity. If the blockchain exists, the evidence exists.
