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 is the developer of the zkSync ecosystem.
In keeping with Polygon Zero, Matter Labs lately launched a proving system known as Boojum with a lot of code copy-pasted from important parts of its recursive SNARK Plonky2. A recursive SNARK is a cryptographic proof that permits one get together (the prover) to reveal to a different get together (the verifier) {that a} sure assertion is true, with out revealing any further data.
Crypto runs on the open supply ethos. When initiatives don’t comply with it, the ecosystem suffers.
We have been upset to see that @zksync copied our code with out attribution and made deceptive claims in regards to the unique work, so we wrote this publish.

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 publish.
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 immediately copied from Plonky2?”
In keeping with Polygon Zero:
“It’s nice to present credit score, and we admire the popularity for our optimization of the Poseidon parameters. Nevertheless, it won’t be obvious to the reader that Boojum borrows way over the Poseidon constants from Plonky2, and in reality that Boojum’s design is almost similar to Plonky2’s, even to the purpose of copy-pasted code.”
Cointelegraph reached out to Matter Labs however didn’t obtain a direct response.
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 similar chain IDs, together with claims that the Shibarium alpha testnet was a duplicate of Polygon’s Mumbai testnet.
