Polygon Zero has accused Matter Labs of copying important codification from its Plonky2 room to zkSync, a rival Ethereum layer-2 scaling solution.
Polygon's zero-knowledge scaling arm, Polygon Zero, is accusing developers of Matter Labs of copy-pasting "a important magnitude of root code" from its Plonky2 library, according to an announcement connected Aug. 3.
The alleged plagiarized codification was recovered connected zkSync, a rival layer-2 scaling solution for Ethereum powered by zero-knowledge technology. Matter Labs is the developer of the zkSync ecosystem.
According to Polygon Zero, Matter Labs recently released a proving strategy called Boojum with tons of codification copy-pasted from captious components of its recursive SNARK Plonky2. A recursive SNARK is simply a cryptographic impervious that allows 1 enactment (the prover) to show to different enactment (the verifier) that a definite connection is true, without revealing immoderate further information.
Crypto runs connected the unfastened root ethos. When projects don’t travel it, the ecosystem suffers.
We were disappointed to spot that @zksync copied our codification without attribution and made misleading claims astir the archetypal work, truthful we wrote this post.

Polygon Zero claims that the codification was included without the archetypal copyrights oregon wide attribution to the archetypal authors. It besides noted that Boojum is highly akin to Plonky2's library. "It uses the aforesaid strategy of parallel repetition to boost soundness successful a tiny field, akin customized gates to efficiently arithmetize recursive verification, and the aforesaid lookup statement developed by our teammate Ulrich Haböck," reads the blog post.
Furthermore, Polygon noted that Matter Labs has marketed Boojum arsenic 10x faster than Plonky2. "Wondering however this is possible, fixed that the performance-critical tract arithmetic codification is straight copied from Plonky2?"
According to Polygon Zero:
"It’s large to springiness credit, and we admit the designation for our optimization of the Poseidon parameters. However, it mightiness not beryllium evident to the scholar that Boojum borrows acold much than the Poseidon constants from Plonky2, and successful information that Boojum’s plan is astir identical to Plonky2’s, adjacent to the constituent of copy-pasted code."Cointelegraph reached retired to Matter Labs, but did not person an contiguous response.
This isn't the archetypal clip plagiarism accusations person surfaced successful the crypto community. In March, a subordinate of the Shiba Inu assemblage reported that Shibarium layer-2 beta testnet and Rinia testnet had identical concatenation IDs, on with claims that the Shibarium alpha testnet was a transcript of Polygon's Mumbai testnet.
