Over the past 1000 blocks, more than 30% of transactions have been below the longstanding1 sat/vB default min tx relay fee limit.

If we plot the actual data, we see spikes around round feerates (1,2,3,4 sat/vB) and a (surprisingly ?) large spike in the sub 1 sat/vB fee rates on the right hand side.

We can animate this graph with a 1000 block sliding window for the month of August.

There is a wide range in the proportion of blocks which are < 1 sat/vB, but the 144 block rolling average has been on an uptrend in recent months (shown here is data since June, block 900000)
