Based on recent data, Lighter's efficiency in using Ethereum blobs is far higher than general-purpose L2 chains like Base. With the same blob space usage, the amount of ETH burned can reach around 5 times (or potentially even more). In the future, as more custom L2 application chains like Lighter emerge, and with the Fusaka upgrade in early December—especially the EIP7918 minimum price guarantee mechanism—Ethereum is expected to capture more revenue from L2 (ETH burn volume is likely to keep increasing, though the overall transaction volume of L2 is also crucial). Lighter has high DA efficiency (the number of user operations packed per blob or the amount of data per byte). Recently, Lighter's user operations per blob reached 450 times that of Base. The main reason lies in its zk state diffs optimization, which only uploads state changes (not full transaction data) on-chain, making it suitable for high-frequency balance updates in perp trading. General-purpose L2s like Base are more "universal," uploading full transaction data on-chain. However, blob space is quickly exhausted, and fewer user operations are packed, resulting in lower efficiency. If L2 application chains can take off, it will be critical for Ethereum's L2 ecosystem and ETH value capture.
