BlockBeats News, April 2nd, Synthetix founder Kain stated in a post that the Ethereum mainnet is facing economic pressure due to reduced Gas fees and ETH burn resulting from L2 scaling off-chain transaction activities and the Blob introduced by EIP-4844 to lower data availability costs. Kain believes that the rise of L2 has captured the revenue that originally belonged to the mainnet, and in the future, shifting to Alt DA solutions such as Celestia is more likely to further weaken the Ethereum mainnet's profitability. To address this issue, he proposed that in the short term, L2 could support the mainnet through official L2 channels or a rent mechanism, while in the long term, it will be necessary to rely on new demands such as tokenization of real-world assets to increase the overall L1/L2 adoption rate. He emphasized that the Ethereum community has an advantage in coordination but should promptly abandon irrelevant projects and focus resources on breaking through the application layer to deal with competitive pressure from L2 and other data availability solutions.
