Blockchain document signature

Published on the January 26, 2021 in IT & Programming

About this project

USD 500 - 1,000

I have an application that needs to be signed through blockchain. It works by events by multiple users uploading a list of documents up to the infinite as an example below.
...
#5 - Document A - User 4
#4 - Document B,C - User 3
#3 - Document Z - User 2
#2 - Document X - User 1 -
#1 - Document J - User 1 - 10:00 am PCT

The main goal is to guarantee the origin of the signature, with proof of authorship. In other words, to guarantee that User 1 is User 1 and what he did and when, and it can't be undone. This sequence of events it's running, but without blockchain, just with a digital signature.
