According to Odaily, Synthetix founder Kain recently highlighted the economic challenges Ethereum's mainnet is facing due to the expansion of Layer 2 (L2) solutions and the introduction of EIP-4844, which reduces data availability costs through Blob technology. Kain noted that the rise of L2 solutions has diverted revenue that traditionally belonged to the mainnet, and future shifts towards alternative data availability solutions like Celestia could further weaken Ethereum's profitability.
To address this issue, Kain suggested short-term measures such as official L2 support or rental mechanisms to allow L2 solutions to benefit the mainnet. In the long term, he emphasized the need for new demands, such as the tokenization of real-world assets, to enhance the overall usage of both Layer 1 (L1) and Layer 2.
Kain stressed that the Ethereum community has a coordination advantage but should decisively abandon unrelated projects and focus resources on breakthroughs at the application layer to tackle competition from L2 and other data availability solutions.
