Analysis: The balance between ETH L1 and L2 can be restored by increasing the minimum blob fee and increasing L2 usage.

Odaily Star Daily News reported that encryption KOL cygaar stated in a post on X: “The relationship between ETH L1 and L2 is currently quite unbalanced.” L2 has gained the benefits of Ethereum security without contributing much value to ETH. I think there are two ways to restore balance:

1. Increase the minimum blob fee Currently, for rollups, the blob cost is essentially zero, which means that Ethereum has virtually no value from L2 DA costs. In the world before EIP-4844, rollups have always been the biggest gas consumption source for ETH, leading to strong deflationary pressure on ETH. However, because the DA blob is basically free, rollups no longer consume too much ETH. This, coupled with the reduction in activity on the Ethereum L1, has led to ETH becoming inflationary again. One possible short-term solution is to increase the base blob fee. L2 must pay a certain amount of fees to use ETH blockchain DA. Some may argue that increasing the cost of ETH blockchain DA will lead to L2 turning to alternative DA solutions, but I believe that chains that truly inherit the security of Ethereum will still pay these costs. 2, increase L2 usage The pricing curve of the current blob is set like this because researchers predict that the demand for L2 will However, except for a few major events (the initial blob release, blobscriptions, LZ Airdrop), the cost of blob has not exceeded the minimum fee. If the demand and usage of L2 increase, we may reach a state where the blob pricing curve can be appropriately priced for DA blobs, resulting in a healthy level of ETH destruction on L1. In addition to the significant cost of DA, the amount of gas used for rollup Settlement may also increase significantly. In the long run, this is the most beneficial approach to the Ethereum ecosystem, but it also requires an inherent demand for L2 Block space. We need more interesting consumer-oriented applications to attract users and drive more on-chain usage. In this world, blob fees will almost never be at the lowest price, and rollups will pay a significant amount to inherit the security of Ethereum.
