Synthetix Founder: L2 and Alt DA Weaken Ethereum Mainnet's Profitability

Synthetix founder Kain stated in a post that the Ethereum mainnet is facing economic pressure due to reduced gas fees and ETH burn rates, caused by L2 expansion diverting transaction activity and the introduction of Blob through EIP-4844 reducing data availability costs. Kain believes that the rise of L2 has intercepted profits originally belonging to the mainnet, and future shifts towards AltDA solutions like Celestia are likely to further weaken the profitability of the Ethereum mainnet. To solve this problem, he suggests that in the short term, official L2 or rent mechanisms can be used to feed back into the mainnet. In the long term, it will depend on new demands such as tokenization of real-world assets to increase overall usage rate for both L1/L2.
