Planet Daily News: Synthetix founder Kain recently pointed out that the Ethereum mainnet is facing economic pressure from a sharp decline in Gas fees and ETH burning due to L2 expansion diverting trading activities and the introduction of Blob by EIP-4844, which reduces data availability costs. Kain believes that the rise of L2 has intercepted revenues originally belonging to the mainnet, and future shifts towards Alt DA solutions like Celestia are likely to further weaken the Ethereum mainnet's profitability. To address this issue, he suggests that in the short term, L2 could feed back to the mainnet through official L2 or rental mechanisms, while in the long term, new demands such as real-world asset tokenization are needed to improve the overall usage of L1/L2. He emphasizes that the Ethereum community has an advantage in coordination, but currently should decisively abandon irrelevant projects and concentrate resources on application layer breakthroughs to cope with competitive pressures from L2 and other data availability solutions.
