Polygon Zero has strongly asserted in opposition to builders of Matter Labs, accusing them of immediately lifting a good portion of code from the Plonky2 Library. This declare surfaced on August 3 and revolved across the alleged replication of code throughout the zkSync platform, an Ethereum layer-2 scaling answer pushed by zero-knowledge expertise.
In blockchain initiatives, it’s frequent for these initiatives to share their code by way of open-source software program licenses. This grants exterior builders the liberty to peruse, replicate, and generally even improve the code as they see match.
But, customary practices throughout the neighborhood, alongside most open-source licenses, usually mandate that unbiased builders give credit score at any time when they combine code sourced from elsewhere.
Matter Labs, accountable for shaping the zkSync ecosystem, has rebuffed allegations of plagiarism, asserting their originality.
Polygon Accuses Matter Labs Of Code Replication, Unattributed Utilization
In a latest weblog publish, Polygon introduced ahead allegations relating to Matter Labs’ new proving system named “Boojum.” Polygon asserts that parts of supply code employed in Boojum have been directly copied from Polygon’s proprietary “Plonky2” software program library.
Crypto runs on the open supply ethos. When initiatives don’t comply with it, the ecosystem suffers.
We have been disillusioned to see that @zksync copied our code with out attribution and made deceptive claims concerning the unique work, so we wrote this publish.

The competition put forth by Polygon Zero emphasizes that the copied code lacks unique copyrights and correct acknowledgment of the preliminary creators.
It additionally highlights exceptional resemblances between Boojum and Plonky2’s library by way of methods reminiscent of parallel repetition for enhanced soundness in a confined area, utilization of comparable customized gates for environment friendly recursive verification arithmetization, and deployment of the an identical lookup argument conceived by their crew member Ulrich Haböck.

Moreover, Polygon’s weblog publish presents further cases the place Matter Labs integrated Polygon’s code with out correct recognition. Polygon has additionally drawn consideration to Matter Labs’ assertion that Boojum boasts a pace benefit of 10 occasions over Plonky2.
Polygon queries the idea for this swifter efficiency, elevating the query of how such a major pace enhancement is feasible when the core area arithmetic code, pivotal for efficiency, seems to have been immediately copied from Plonky2.

Matter Labs Responds To Polygon’s Assertions
In mild of the allegations by Polygon, Matter Labs has taken steps to handle the issues surrounding its Boojum proof system. The corporate clarified {that a} mere 5% of the Boojum code attracts inspiration from Plonky2, and this supply is explicitly acknowledged proper on the outset of its codebase.
CEO Alex Gluchowski took to Twitter to comprehensively reply to the state of affairs. Expressing his disappointment with Polygon’s allegations, Gluchowski reaffirmed {that a} mere 5% of the Boojum codebase is predicated on Plonky2’s code.
Each choice we make as a crew in the direction of constructing @zksync is pushed by our ethos, which is predicated on integrity and transparency. We’ve made trustworthy errors prior to now, however we at all times did our greatest to overtly acknowledge them and take duty. And can at all times achieve this within the… https://t.co/4yjpSCHC2d

He underscored that Boojum and Plonky2 embody implementations of the Redshift idea, which he maintained was launched by Matter Labs three years earlier than Polygon publicized the Plonky2 paper.
