On the Software Heritage archive portal, more than 4 billion files from more than 80 million origins are available since June 7, 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.
