- The Polygon division responsible for developing the Plonky2 library has criticized Matter Labs.
- The company has been accused of plagiarizing and stealing source code for its Boojum solution.
The Polygon Zero project team has claimed that Matter Labs stole some of the source code for its Boojum solution. The organization denied the allegations.
“The entire cryptocurrency industry operates on the principle of open source. When projects don’t follow it, the entire ecosystem suffers. We were disappointed to see that the zkSync [Matter Labs development] team copied the source code without attribution and made several misleading claims about the originality of the work,” Polygon Zero said in a statement.
The library in question is Boojum, introduced in mid-July 2023. Polygon Zero claims that much of it is written on the source code of the SNARK Plonky2 recursive proof of SNARK. Examples and proofs can be seen in a separate article.
The Plonky2 can be accessed by anyone who wishes to do so. However, Matter Labs, as Polygon Zero claims, did not cite authorship, attributing the development to itself. Moreover, the company has positioned its solution as more efficient.
In comments to Cointelegraph, a Matter Labs spokesperson denied accusations of plagiarism. He emphasized that the Boojum system borrows only about 5% of Plonky2, which is stated in the first line of the module’s code, according to the company.
An earlier, Joel Dietz made similar accusations, but already against Consensys. He said he authored the idea for the wallet, which would later come to market under the name MetaMask.
