The main source of income for the Ethereum network from Layer2 expansion chain, "Blob fees", has fallen to its lowest weekly level this year. Etherscan pointed out in a post on platform X that in the week up to March 30th, Ethereum only earned 3.18 ETH (about $6000 calculated at April 1st prices) through Blob fees. This figure is down 73% from the previous week and more than a staggering 95% drop from the peak of 84 ETH during the week of March 16th.
