Does Functional Package Management Enable Reproducible Builds at Scale? Yes.

[Julien Malka]

Hi everyone,
Very happy to share a research article to be published at MSR’25 that I wrote under the supervision of Stefano Zacchiroli and Théo Zimmermann:

« Does Functional Package Management Enable Reproducible Builds at Scale? Yes. » [1]

The article explores the proportion of bitwise reproducible packages in the Nix package repository and its evolution between 2017 and 2023.

Available to answer any question from folks here :)

Best,
Julien
