Polygon Claims Matter Labs Copied Its Code Without Attribution

In its blog post, Polygon included several screenshots comparing its own code to that of Matter Labs. In a screenshot of a Matter Labs file titled “mod.rs,” Polygon captioned that it contained “no attribution for the original authors.” Matter Labs CEO Alex Gluchowski linked to that same file in a tweet. The first line of that file, which was excluded from Polygon’s screenshot, reads, “NOTE: we take a Plonky2 implementation of non-vectorized field as the baseline.”
