Odaily Planet Daily News Polygon Zero published a blog post stating that Matter Labs, the developer of zkSync, recently released a proof system called Boojum, which contains a large number of source codes copied and pasted from performance-critical components of the Plonky2 library.
Additionally, the Matter Labs founder claims that Boojum is more than 10 times faster than Plonky2.
Polygon Zero believes that copy-pasting source code without attribution and making misleading claims about original works violates the spirit of open source and damages the ecosystem,
Earlier news, Polygon Zero announced Plonky2, calling it the fastest ZK expansion technology.
