"Blob fees", the network's main source of revenue from the Layer2 extension chain, have fallen to their lowest weekly level this year. Etherscan pointed out in a post on the X platform that in the week ended March 30, Ethereum earned only 3.18 ETH (about $6,000 at April 1 prices) through blob fees. This figure is down 73% from the previous week, and has plummeted more than 95% from the peak of 84 ETH in the week of March 16.
