Replace (Aug. 3 at 9:49 p.m. UTC): This text has been up to date so as to add Matter Labs’ response.
Polygon’s zero-knowledge scaling arm, Polygon Zero, is accusing builders of Matter Labs of copy-pasting “a considerable quantity of supply code” from its Plonky2 library, in line with an announcement on Aug. 3.
The allegedly plagiarized code was discovered on zkSync, a competitor layer-2 scaling resolution for Ethereum powered by zero-knowledge know-how. Matter Labs, the developer of the zkSync ecosystem, has denied the claims.
Based on Polygon Zero, Matter Labs not too long ago released a proving system known as Boojum with plenty of code copy-pasted from vital elements of its recursive SNARK Plonky2. A recursive SNARK is a cryptographic proof that permits one social gathering (the prover) to reveal to a different social gathering (the verifier) {that a} sure assertion is true, with out revealing any extra data.
Crypto runs on the open supply ethos. When tasks don’t observe it, the ecosystem suffers.
We have been disillusioned to see that @zksync copied our code with out attribution and made deceptive claims concerning the authentic work, so we wrote this put up.

Polygon Zero claims that the code was included with out the unique copyrights or clear attribution to the unique authors. It additionally famous that Boojum is extraordinarily much like Plonky2’s library. “It makes use of the identical technique of parallel repetition to spice up soundness in a small area, comparable customized gates to effectively arithmetize recursive verification, and the identical lookup argument developed by our teammate Ulrich Haböck,” reads the weblog put up.
Moreover, Polygon famous that Matter Labs has marketed Boojum as 10x sooner than Plonky2. “Questioning how that is attainable, on condition that the performance-critical area arithmetic code is instantly copied from Plonky2?”
Based on Polygon Zero:
“It’s nice to offer credit score, and we respect the popularity for our optimization of the Poseidon parameters. Nevertheless, it may not be obvious to the reader that Boojum borrows excess of the Poseidon constants from Plonky2, and actually that Boojum’s design is almost equivalent to Plonky2’s, even to the purpose of copy-pasted code.”
In feedback to Cointelegraph, Matter Labs expressed disappointment to see Polygon’s management group “spreading unfaithful claims.” Based on a spokesperson, “the brand new Boojum high-performance proof system leverages 5% of from Plonky2, which is prominently attributed within the first line of our module. The place else, apart from the very first line of our library would this have been included if we wished it to be extra outstanding?”

This isn’t the primary time plagiarism accusations have surfaced within the crypto group. In March, a member of the Shiba Inu (SHIB) group reported that the Shibarium layer-2 beta testnet and Rinia testnet had identical chain IDs, together with claims that the Shibarium alpha testnet was a duplicate of Polygon’s Mumbai testnet.
