Does number of transactions in the block affect it's mining time?

How and why?

1 Answer 1


The number of transaction in a block negligibly effects the mining time. The only effect is that more computations need to be done to calculate the merkle root during block construction, but that is a very small fraction of the number of calculations needed to be done during mining itself. Mining only hashes a fixed amount of data so including more or less transactions does not really make a difference.
