Transaction Fees per Block in US Dollars shows the total daily fees paid to miners, converted into USD. It is the fiat-value companion to the native satoshi total, so it describes the economic scale of fee demand rather than fee flow in BTC terms.
A rising series means block-space demand is producing more fee value in dollar terms. A falling series means fee support is smaller economically. It is most useful with Transaction Fees per Block in Satoshis, Miner Revenue in USD, and Hash Price.
The key caveat is denomination. This series moves with both fee volume and BTC price, so a higher USD reading does not by itself mean the native fee market became stronger.
