Sort:  

hi @crokkon, yes I did investigate because crave was the first one and I thought I made a mistake somehow. So I went to the developers and confirmed with them the data contained within their apis.

The blocks are not empty as they do include MN rewards and staking rewards but other than that you would be correct in assuming no transactions are happening. Thanks for bringing this up as I can use it in future analysis as a comparison metric. Some sort of value per block
