Why are there blocks with just one "txcount"? Does it exist a correspondence with param "maximum-block-size = 8388608"?

 

Thank a lot

Answer 1

Every block has at least one transaction in it, called the coinbase transaction. This is used to embed the miner signature and (if relevant) control where the miner's reward is sent.
