Drama in the Layer 2 realm again!
Polygon openly criticized zkSync for copying their code without indicating attribution, showing no open-source spirit. They're not pleased that zkSync claimed their Boojum is 10 times faster than Polygon's Plonky2.
zkSync retorted saying they only used 5% of the code, and they did mark the source as this code is open-source. They also insinuated that it was Polygon who lacked the open-source spirit.
StarkWare seized the opportunity to step on its rival zkSync, expressing disappointment in their actions. They urged the two to resolve the matter for the sake of fairness in the world.
Some individuals who thoroughly read the related articles noted that zkSync didn't indicate the source for all copied sections, only slightly implying it.
