The launch of Sony's Layer 2 blockchain, Soneium, has sparked controversy over its alleged blacklisting of some memecoins that infringe intellectual property rights. The move reportedly took place on the day of the network's launch, apparently resulting in some tokens being restricted, making them untradable and unsupported by official blockchain explorers. The blacklist specifically targets tokens that imitate or use brands that Sony or Soneium deem protected. Trading in these memecoins has reportedly been stopped and cannot be transferred. Users attempting to access these tokens receive a ban alert on the block explorer. Sony Block Solutions Labs, the multinational conglomerate's Singapore-based blockchain subsidiary, launched Soneium earlier today. In its announcement, the Soneium developer emphasized the need to strengthen the intellectual property rights of creators and fans.
