币界网报道：The Ethereum network experienced a significant surge in gas fees, with the average transaction cost spiking to 155 gwei, the highest level since May 2023, due to heightened on-chain activity. This spike was primarily driven by the popularity of the new ERC-404 token standard, particularly the Pandora NFT collection, which accounted for 15% of all gas consumption. The ERC-404 standard, which combines aspects of ERC-20 and ERC-721 tokens to enable fractionalized NFT ownership, has seen rapid adoption, with Pandora's trading volume exceeding 10,000 ETH. The increased demand led to network congestion, causing delays and higher costs for users. Analysts suggest this highlights Ethereum's ongoing scalability challenges despite recent upgrades. Meanwhile, developers continue to explore layer-2 solutions and alternative standards to address these limitations while maintaining security and decentralization.
