Bitstamp verification duration meaning
Create account Sign in. How does it work? Record photographic evidence of something today and timestamp it so no-one can say it was post-edited. We don't know if it'll stand up in court, but for informal mediation of disputes, this might be useful. No guarantees from us though, please see legal considerations.
See some screenshots on the Ink Factory blog that's us. We're in beta a work in progress - it will be possible to extend file hosting period before expiry. The blockchain is distributed across the internet and maintained by thousands of computers, so transactions can't be deleted or backdated. We will generate a QR code graphic which links to a verification page - you insert the graphic into the footer of your document, and when printouts are circulated it will serve as a deterrent against plagiarism.
As long as you retain the original file, you will always be able generate the signature to prove that it existed when you Bitstamped it. We store the SHA digest checksum of the uploaded file prefixed with some marker bytes on the Bitcoin Blockchain.
We didn't invent timestamping checksums on the Blockchain; our objective is to provide an easy to use interface to complete that task and provide a service for users to print a verifiable timestamp on their documents. This is possibly the first non-currency application of the Bitcoin Blockchain packaged in a commercial way for non-technical users. We do not know if a Bitstamped document would be more useful in a court case than a non-Bitstamped document. All services are provided as-is.
You should retain your own copy of any files submitted. Blockchain timestamps will remain useful forever, or for as long as the Blockchain and your original file exist. When a document has been timestamped on the Blockchain, the timestamp and checksum are immutable, but you should not rely on Bitstamped. In any event, total liability shall not exceed the fee you have paid to use Bitstamped. Use of this service means you accept these terms. If in doubt, you should seek legal advice. Prove that file existed today Bitstamped is great for: What is it, and what is it for?
We create a publicly verifiable timestamp that you can add to printed documents using a QR code.

Or use it to show you came up with an idea first - unless of course you didn't. No guarantees from us though, please see legal considerations You can choose whether to share your Bitstamped file publicly, now, later, or never.
Embed this cartoon on your own site Bitstamped. What does it cost? Simple answer Technical answer Using encryption, we calculate a unique signature or fingerprint for your file.
We store that signature with the current date in a public ledger called the blockchain. You can choose to make your file available for download at the verfication URL, or not. Modifying your file will change the signature, and it will not match the Bitstamped signature.
The file checksum can be used to prove that the file existed at the time it was Bitstamped.
