According to PANews on April 2nd, Synthetix founder Kain recently pointed out that the Ethereum mainnet is facing economic pressure from a sharp decrease in Gas fees and ETH burning due to L2 expansion diverting transaction activities and Blob reducing data availability costs introduced by EIP-4844. Kain believes that the rise of L2 has intercepted revenues originally belonging to the mainnet, and future shifts towards alternative data availability solutions like Celestia are likely to further weaken the mainnet's profitability. To address this issue, he suggests that in the short term, L2 could support 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 emphasized 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.
