On the Software Heritage archive portal, more than four billion files from more than 80 million origins are available since 7th June 2018, date of the official opening ceremony held at the UNESCO, in the presence of sponsors and partners of Software Heritage. 

The Software Heritage archive plays an important role in Open Science: it preserves software source code, ensuring it will be accessible in the long term, and provides intrinsic persistent identifiers for software artefacts that enable not only access, but also verifiable integrity, contributing to making reproducibility and assessment of science more resilient. The long term goal of the Software Heritage initiative is to collect all publicly available software in source code form together with its development history, replicate it massively to ensure its preservation, and share it with everyone who needs it.
