Odaily News Gautham Santhosh, co-founder of Polynomial, warned that the continued demand for Ethereum Layer 2 is rapidly exhausting the mainnet blob capacity, with 55% of blobs currently occupied by BASE and World Chain. Since November last year, the blob base fee has exceeded $50 several times, causing a sharp increase in user transaction costs. The Pectra upgrade, which will be launched in March, will increase the blob limit per block to 9, but Santhosh believes that this can only temporarily alleviate the problem, and long-term expansion still requires more solutions.
