I need a service where I can submit a URL of a web page and then download a blockchain-timestamped screenshot of the web page, proving the web page existed in a certain way at a certain time with no possibility that I had altered or forged the screenshot.


  • Service needs to take screenshot or raw archive of webpage
  • The archive should include a timestamp of when the fetch took place
  • A signature of the content and timestamp should also be provided
  • Needs to work with Twitter, Facebook, Instagram, news sources, etc.

Suggested Solution

The service could implement this with a blockchain to prevent tampering.
