最新报道:A new study reveals that Ethereum's rollup networks are mispricing small transactions due to oversimplified fee mechanisms, leading to inflated user costs and vulnerability to denial-of-service attacks. Researchers found that most rollups fail to separately account for computation, data availability, and proof costs, instead using single formulas or fixed rules. This allows attackers to exploit underpriced transactions for spam attacks while honest users overpay. The study calls for multidimensional fee structures to align pricing with actual resource use and improve system resilience.
