Polygon Zero, the zero-knowledge extension division of Polygon, has accused Matter Labs developers of copying a significant amount of source code from its Plonky2 library, as per an announcement on August 3rd.
The allegedly copied code was found on zkSync, an Ethereum layer 2 scaling solution built on zero-knowledge technology. Matter Labs, the creator of the zkSync ecosystem, has refuted these allegations.
According to Polygon Zero, Matter Labs recently introduced a proof system named Boojum, which includes a substantial amount of code directly taken from key parts of its recursive SNARK Plonky2. A recursive SNARK is a cryptographic proof that allows a prover to demonstrate a statement's truth to a verifier without revealing any further information. Polygon Zero allegations that the incorporated code lacks original copyright or proper attribution. They also highlight the remarkable similarity between the libraries of Boojum and Plonky2.
Furthermore, Polygon points out that Matter Labs promotes Boojum as being 10 times faster than Plonky2. This raises questions about the legitimacy of this claim, given that crucial field arithmetic code, directly copied from Plonky2, drives this suppos ed speed boost.
Matter Labs expressed disappointment over what it considers falsehoods being spread by Polygon's leadership. According to Matter Labs' spokesperson, the new Boojum high-performance proof system employs only 5% of Plonky2, as indicated in the first line of their module. They questioned the The accuracy of Polygon's claims and emphasized that other than the first line, their library is distinct.
Plagiarism allegrations are not new to the crypto community. For instance, Earlier This year, the shiba inu community reported that the shibarium lay 2 beta testNet And the rinia test shared the same chain id, Asserting that the shibarium alpha testnet was essentially a copy of the Polygon Mumbai testnet.
