Certified Spin · a NameWheel first

The verified wheel spin. With video proof.

Run your giveaway on a wheel that records itself, locks the outcome with our TrueSpin engine before it moves, and publishes a proof page anyone can check. Post the link. When someone asks if the draw was real, they can verify the wheel spin themselves in ten seconds.

Definition

A verified wheel spin is a random draw whose outcome is sealed by NameWheel’s TrueSpin engine before the wheel moves, recorded on video with sound, and published to a permanent proof page where anyone can re-run the math and confirm the winner, the entries and the exact time of the draw.

The problem

Every giveaway winner gets the same comment

Rigged. Her cousin. He always picks mods. Anyone who has hosted a giveaway on Instagram, Twitch or a classroom smartboard knows the comment section that follows the winner announcement. Screen recordings do not help, because everyone knows you can spin until your friend wins and record the last attempt, or swap a name in an editor afterward. The audience is right to doubt a plain video. It proves nothing.

A certified spin flips the burden of proof. The draw happens inside a protocol the host cannot steer, the video is stamped and hosted where the host cannot touch it, and the record answers the doubters so you do not have to.

The TrueSpin engine

How a verified wheel spin works

The server commits

Before the wheel moves, our server locks a secret seed and publishes its fingerprint. From this moment the randomness cannot be swapped, by you or by us.

commit = SHA-256(seed)

Your browser adds entropy

Your own device contributes randomness the server never chose. The winner comes from both together, so neither side alone controls the outcome.

winner = HMAC(seed, entropy | entries)

The wheel spins on camera

The spin is recorded as a produced clip: your title, live physics, real sound, the winner card, and the proof link on every single frame.

1280 x 720 MP4 · sound included

The record goes public

The seed is revealed, the record is signed with our published key, the video is hashed and hosted, and your proof page goes live at a short link.

What a skeptic sees at the link

The hosted video, the full entry list, the exact draw time, the winner, and how many certified draws the host ran that day. Then one button that re-runs the entire draw in their own browser and shows every check pass. Not our word. Their computation. See it live on a real proof page right now.

Four words worth knowing

TrueSpin engine

NameWheel’s draw protocol. The server seals its randomness before the spin, your browser adds its own, and the winner comes from both together, so neither side alone controls the outcome.

Commitment

A fingerprint of the secret seed, published before the wheel moves. Once revealed, anyone can confirm the seed matches, which proves the randomness was not swapped after the fact.

Proof page

The permanent public record of one draw: entries, winner, exact time, hosted video and the live math check. It cannot be edited or deleted by the host or by NameWheel.

Draw code

The short address burned into every frame of the video, like namewheel.org/v/NT49TV59. Type it anywhere the video was posted and the proof page opens.

Straight about the limits

What it proves, and what it does not

A certified spin proves

  • The draw ran at the stated time over exactly these entries
  • The winner came from committed randomness neither side could steer
  • The hosted video is the untouched original, byte for byte
  • The record was never edited after the fact, by the host or by us
  • It cannot prove

  • What the host did off the record, which is why every proof page shows the host's certified draw count for that day
  • That the prize was actually delivered afterward
  • That the entry list itself was collected fairly
  • The complete byte-level protocol is documented in the TrueSpin specification, with an open source verifier on GitHub that re-runs any draw offline. We publish the limits because a proof that oversells itself is not a proof. The wheel's core randomness is separately testable by anyone, any time, in the Fairness Lab.

    Who needs this

    Built for rooms full of doubters

    Streamers and creators

    Your sub giveaway becomes a clip worth posting and a link worth pinning. Chat can check the draw mid-stream, and the accusation thread dies before it starts. Pairs with the OBS setup in minutes.

    Brands and communities

    A Women's Month giveaway, a product launch draw, a Discord raffle. The proof link goes in the announcement post, and every entrant can confirm their name was on the wheel when it spun.

    Schools and offices

    Who presents first, who gets the last conference ticket, who won the charity raffle. The proof page settles it permanently, and nobody corners you by the coffee machine on Monday.

    First video free. Verification free forever.

    Your first certified spin video is on us, finished with a short NameWheel outro card. After that, PRO makes them unlimited with no outro at all, from $4.08 a month. And verification is never paywalled for anyone: the record, the signature, the math and the proof page stay public, because trust you have to pay to check is not trust.

    Verified wheel spin questions

    What is a verified wheel spin?
    A verified wheel spin is a random draw where the outcome is locked by NameWheel’s TrueSpin engine before the wheel moves, recorded on video with sound, and published to a permanent proof page. Anyone with the link can re-run the math in their own browser and confirm the winner was not chosen by the host, not edited afterward, and drawn at the stated time.
    How do I verify someone's wheel spin video?
    Look for the proof link burned into the video, like namewheel.org/v/NT49TV59, and open it. The proof page shows the full entry list, the winner, the exact draw time, and a Check the math yourself button that recomputes the result live in your browser. If the video you saw shows a different winner than the page, the video was edited.
    Can the host fake a certified spin?
    The host cannot pick the winner: it comes from a server seed committed before the spin combined with entropy from the host's browser, so neither side alone controls the outcome. The host also cannot edit the record or the hosted video, and the proof page lists every certified draw that host has started with this same entry list, including any they started and never published, so quietly re-spinning until a friend wins is visible rather than hidden.
    Does the video work on Instagram and TikTok?
    Yes. Every certified spin is published as a standard MP4 you can download and post anywhere, with the proof link burned into the frame. On X, Discord, Telegram and WhatsApp you can post the proof link itself and the video plays inline.
    Is the verified wheel spin free?
    Running certified draws and publishing proof pages is free for every signed in account, and verification is never paywalled for anyone. Your first hosted video is free and closes on a short NameWheel outro. After that, PRO includes unlimited clean videos in both 16:9 and Reel-ready 9:16, from $4.08 a month, and the $99 Founder licence makes it lifetime.
    What happens if the winner does not respond?
    Run another certified spin. Each draw gets its own numbered record, and the proof pages show the sequence honestly, so your audience can see draw one had no response and draw two picked the replacement. Transparency about redraws builds more trust than pretending the first one never happened.
    How do I prove my giveaway is fair?
    Run the draw as a verified wheel spin on NameWheel. The outcome is sealed before the wheel moves, the spin is recorded with the proof link on every frame, and the permanent proof page lets any viewer re-run the math themselves. Post the link with your winner announcement and the accusation thread answers itself.
    Can a giveaway video be faked?
    An ordinary giveaway video can be faked easily: hosts can re-spin until a friend wins, edit the winner name in any video editor, or misstate when the draw happened. A verified wheel spin closes all three doors, because the winner comes from sealed randomness, the hosted original is hashed, and the record carries a signed server timestamp.
    How do streamers prove giveaway winners on Twitch?
    Run the certified spin on stream, then pin the proof link in chat. Viewers can open it mid-stream, watch the hosted video, see the full entry list and re-run the draw math in their own browser while you keep streaming. The wheel captures cleanly in OBS as a browser source.

    Your next winner announcement defends itself.

    Open the wheel, tap Certified Spin Video, and run the first draw your audience can actually check. It takes one minute and it is free.
