Speaking of the largest block. what is the smallest block with the least transactions within a year? I mean there has to be a block with maybe like 50 transactions right?
I don't know the answer, but I think one could create a block with no transactions. I think?
But I mean in "modern times" arent there transactions every millisecond? How could one be created with 0?
There's no block with 0 transaction. By definition a block contains at least 1 tx, the coinbase tx.
Anyway look at the link that a good soul shared a few posts ago and you'll find the answer you're searching for.
For your convinience
Blocks with 1 transaction: 84607
