If Ethereum's EIP-4844 is implemented (expected next year), it will be a great benefit to L2, because transaction fees will be significantly reduced. This is a big negative or competitive pressure for other L1 public chains. The scalability of Ethereum has been greatly enhanced, and the ecology will become increasingly rich. From now on, Ethernet will be used as the basic chain, and other L2 will be used for various different and rich applications. EIP-4844 will be a qualitative improvement for L2 of arbitrum and optimization. Let us witness the progress of Ethereum every year.
