What is tProof?

tProof is a certification platform that allows users to make use of blockchain technology to create immutable proof of a file's existence.

With tProof, you're able to certify the files existence on a certain date, creating better clarity around when something is created for future reference.

What problem does tProof solve?

identifying the original creator of artwork, or even information based documents, can be a real problem.

Every week you'll find something on social media where someone calls out a poster for stealing their post or artwork from someone else.

The reality of finding out who the original creator is can be a difficult task.

And if things ever get to the point where legal action is taken, there's going to need to be a lengthy discovery process to find the original instance of an asset.

tProof could help put an end to this.

With tProof, users are able to add a certification time stamp to any file, effectively proving the very latest point an asset is created and who created it.

This could help artists who are targets for plagiarism prove they were the first person to create and share an asset.
