Screenshot on the blockchain
Prove what a pagesaid, before it changed.
Posts get deleted. Prices get edited. Terms get quietly rewritten. Paste the address and this site opens it in a browser we run, photographs it, hashes the picture and writes that hash down on a chain — so the timestamp is not your word against theirs. A$9 a screenshot.
You pay on Stripe’s own page and come straight back to your receipt. We never see a card number. The picture is usually ready within a minute of the payment clearing.
What you get
- The picture. A full-size PNG of what that address served our browser, downloadable from your receipt for good.
- Its SHA-256. Anyone can hash the file you hand them and compare it to the receipt. If a single pixel changed, the hash does not match.
- The exact instant, to the second, in UTC, by our clock at the moment the shutter went.
- The address the browser actually ended on, redirects followed — which is not always the address you typed, and the difference is sometimes the whole story.
- A transaction on mainnet-beta carrying a hash of all four facts bound together. After that, the timestamp survives us: it is stamped by a network none of us controls.
What it is not
- Not proof the page was telling the truth. It is proof of what was served, at that moment, to us. A lie captured faithfully is still a lie, and this receipt says only that it was there.
- Not proof of who wrote it. We photograph an address. We do not verify an author, an account or a company.
- Not a legal instrument. It is strong evidence and it is not a notarised document, an affidavit, or advice. If something turns on it, show it to a solicitor.
- Not a capture of what you see. Pages behind a login, a paywall or a country block serve our browser something different, and what you get is what we were served.
Who buys this
Somebody who has been told “we never said that”. A moderator keeping the post before it is edited. A journalist holding a page that is about to be quietly corrected. Anyone in a dispute where the other side controls the website.
A screenshot you took yourself is worth what the person looking at it thinks of you. This is worth the same to a stranger as to a friend, which is the only difference that matters and the whole of what you are paying for.
