Questions, answered.

Pudding gives everything you publish a permanent, public receipt — proof that you posted it, when you posted it, and that it hasn't been altered since.

Claim your profile, verify at least one account or website you publish from, then register a piece of content. Registering takes about thirty seconds: paste the URL or attach the file, and you get a public Proof Record page you can link to anywhere.

Only for content from a platform you're claiming. If you paste a link to a post on a channel you haven't verified yet, we'll ask you to verify that channel first — otherwise anyone could claim anyone's posts. Files you upload directly don't need a channel.

Yes. The whole flow works in a mobile browser, including attaching a photo or video straight from your camera roll. You can also add Pudding to your home screen and it will open like a normal app.

No. Pudding runs entirely in your browser. There's no extension, no desktop app, and nothing to keep updated.

A fingerprint is a SHA-256 hash: a short string of characters derived from your exact file or URL. Change a single pixel and the fingerprint changes completely. It works one way, so the fingerprint reveals nothing about the content itself — but anyone holding the original can recompute it and confirm it matches.

Your fingerprint gets bundled with other recent records into a single combined value, and that value is submitted to the Bitcoin blockchain through OpenTimestamps. Once it's included in a Bitcoin block, the timestamp is backed by the same public record everyone else can read — not by Pudding's word.

Three things: that this exact content existed at the time it was registered, that it was registered by an account that had verified control of a specific channel, and that it hasn't been modified since. Anyone can check all three without an account and without trusting us.

It doesn't prove you created the content, that you own the copyright, or that anything you said is true. It proves timing and integrity, not authorship or accuracy. We'd rather say that plainly than oversell it.

Yes, and it's important you know that. Anyone can register a fingerprint of anything. Pudding records who registered what and when — it does not decide who created something. What makes your record persuasive is that it's earlier and comes from a channel you've verifiably controlled. That's strong evidence in a dispute, not a ruling on ownership.

It helps you demonstrate you published first. You can point to a public record, timestamped before their post, tied to your verified account. Most platforms' copyright and impersonation processes ask for exactly that kind of evidence. Pudding doesn't file the claim for you.

No. Pudding is not a certification body, legal witness, or escrow service, and a Proof Record is not a court judgment. It's an authenticity signal that a person or a platform can independently check. Treat it as evidence, not as a verdict.

Ideally you shouldn't have to. The fingerprint is computed on your device, the record is public, and the timestamp is anchored to Bitcoin — so you can verify a record with open-source tools even if Pudding disappeared tomorrow. That's the point of the design.

Your file is hashed in your browser before anything is sent. If you choose to attach the file, it's stored privately and only you can access it — it is never published. If you'd rather not upload at all, register the URL instead and only the fingerprint leaves your device.

Your username, display name, bio, verified channel handles, and your Proof Records — each showing the title, fingerprint, timestamp, and anchoring status. The content files themselves stay private unless you've published them somewhere yourself.

The Proof Record stays. That's usually what you want: it's a record that the content existed at a point in time, which survives the post being edited, deleted, or taken down by a platform. If you have the original file, you can still prove it matches.

Your profile and records come down with it. Before deleting, download anything you want to keep — the fingerprints and timestamp proofs are portable and remain verifiable on their own.

Not from the fingerprint — a hash can't be reversed. If you upload a file for safekeeping we hold it in private storage, so treat that the way you'd treat any cloud storage. If that matters to you, register the URL and skip the upload.

GitHub, Substack, and YouTube using a short code in your public bio; your own website using a DNS record or a file; your email address; and Mastodon using the open rel=me standard. Email and website are the most reliable of these.

Our check works by reading your public profile page from our servers. Those platforms don't allow that — they return a login wall or an empty page to anything that isn't a signed-in browser. Rather than let you paste a code and fail, we've marked them as coming soon until we ship official sign-in for each one.

Your own website via a DNS record, or your email address. Neither depends on another company's policy, and both work the first time. If you have a domain, verify it — it also lets you register anything you publish there.

Never. We only read a public profile page to look for the code you added. Pudding cannot post, message, follow, or change anything on any platform, and we don't ask for permissions that would let us.

Records already registered stay valid — they captured what was true at the time. You'll want to re-verify under the new handle so your profile keeps showing an accurate, current channel.

Because a timestamp is only as trustworthy as whoever issued it. Anchoring to Bitcoin means the proof doesn't depend on Pudding still existing, still being honest, or still being online. It's the most independently checkable clock available.

No. There's no wallet, no coins, no fees, and nothing to buy or manage. We use Bitcoin purely as a public timestamp. Most people will never think about it.

Your fingerprint is permanent the moment you register it. The Bitcoin confirmation typically lands within one to six hours, and the record page updates on its own to show the block it landed in. Nothing is lost while you wait.

Yes, and that's the whole design. Recompute the fingerprint from the original, walk the short list of sibling hashes we publish up to the batch value, and check that value against Bitcoin using any OpenTimestamps client. None of those steps require us.

Ten Proof Records a month, forever, with a public profile, verified channels, and full Bitcoin anchoring. Free records are not weaker records — they get the same proof as paid ones.

Unlimited Proof Records for twelve dollars a month, for people publishing more than ten things a month. Cancel whenever you like.

Yes — registered 501(c)(3) organizations and equivalent charities outside the US get fifty percent off Pro. Apply through institutional verification and include your EIN or charity registration number, and we'll apply it once we've reviewed your status by hand.

They stay public and stay verified. Anchoring is permanent and doesn't expire with a subscription — cancelling just returns you to the free monthly limit for new records.
