How to Timestamp Your Content with TextProof

Content timestamping creates a verifiable record that a specific piece of text existed at a specific point in time. Writers use it when they want evidence for prior authorship, when they need a defensible draft history for client work, or when they want a neutral record before publishing original research or commentary.

1. You paste your original text into the TextProof timestamp tab.
2. The browser computes a SHA-256 fingerprint locally so the raw text never leaves your device.
3. TextProof sends only that fingerprint to OpenTimestamps calendar servers.
4. Those calendar servers anchor the fingerprint to Bitcoin and TextProof returns a downloadable `.ots` proof file.

1. Open the verify tab on `/proof/`.
2. Paste the original text that was timestamped.
3. Upload the `.ots` proof file you downloaded earlier.
4. Let TextProof compare the browser-side hash of the original text with the proof record and confirm the anchored block details.

OpenTimestamps is an open protocol for timestamping data without trusting a single company. Calendar servers collect timestamp requests, merkleize them together, and later commit that proof chain to Bitcoin, which acts as the long-term public trust anchor.

TextProof hashes your text in the browser, sends only the fingerprint upstream, and stores the `.ots` proof file as the portable verification artifact. The raw text is not transmitted to calendar servers, and the proof can be verified later only when someone has both the original text and the proof file.

TextProof is useful for writers protecting drafts, journalists documenting first publication, researchers preserving authorship evidence, freelancers proving delivery timing, and creators who want a neutral record before publishing or sharing original content.
