The aim of the startup LibScience is to put scientific publishing back in the hands of researchers. Drawing on the capabilities of Web3 and the blockchain, the purpose is to reshape scientific publishing by making it open and decentralised. After a year of maturation within Inria Startup Studio, a first version integrating publication in a decentralized open archive was deployed on a test network in order to evaluate and improve the tool's basic functionalities with a view to its public opening.
