What's a Timestamp?
A timestamp proves your file existed at a specific time. It's like a digital notary stamp that can't be faked. Only the file's fingerprint goes on Bitcoin's ledger.
Why It Matters
- •Legal proof — show when contracts were signed
- •IP protection — prove when you created something
- •Audit trails — track document versions
Pro Tips
- •Timestamp emails as .txt files first
- •Zip multiple files and timestamp the archive
- •Back up .ots files separately
