What is PACWeb?

PACWeb is a revolutionary tool that allows users to collect and prove the authenticity of content published on various online platforms like websites, blogs, and social media. By making a full copy of the viewed content, it generates a unique hash as an identifier and provides a report. Leveraging advanced blockchain technology, it ensures that the evidence hasn't been tampered with and maintains a timestamp for added security. The collected evidence is certified through the OriginalMy platform; thus, making it legally valid. It's designed predominantly for legal proceedings and holds validity in Brazil, although users outside Brazil may also find it useful.

Defamation, bullying, fake news or others? Download our plugin for free on a Chrome browser and collect evidence at any time, anywhere.

The solution Proof of Authenticity for Web Content makes a full copy of the content being viewed on your browser and automatically generates a report proving its existence. It is possible to register the authenticity of content published on the web, be it on websites, blogs, social media platforms or portals. Additionally, from the report, a hash - a unique and exclusive code - is calculated, which identifies your document on our website.

For that, we use the most advanced technology: the blockchain. With a register on blockchain, it is possible to prove that the evidence was not modified, with the content being preserved even if the original publication is deleted. It has also an additional lawyer of protection with the timestamp, which indicates the precise date and time that the evidence was collected.


  • The plugin can only be installed on Chrome browser. After the installation, we recommend that you reload the browser or the tabs with the content you want to collect.

  • In the case of social media, try to use the link to the specific post.

  • To use the plugin, simply click on the extension icon, which can be found on the top right corner of your browser.
