Why do bitcoin blocks take a lot of time to mine?
Could you elaborate on why it takes a considerable amount of time to mine Bitcoin blocks? I've heard that the process is computationally intensive and requires significant resources. Is this the primary reason for the delay? Does the difficulty of mining increase over time as more miners join the network? Additionally, what impact does the block reward have on the mining speed? Is there a way to optimize the mining process to reduce the time taken? Clarifying these aspects would help me better understand the intricacies of bitcoin mining.
