What is the difficulty of bitcoin mining?

Question

blockchain

Hello. I'm trying to understand the algorithm for finding a cache for a bitcoin block. As I understand it, it all comes down to finding the right nonce. But after all, it is limited to 32 bits, and there can be a maximum of 4,294,967,295. And what are we talking about when the capacities of mining farms are calculated in terahashes? After all, then the blocks would be located in less than a second.

Answer 1

They have been using an additional transaction for a long time, and changing it (at one time they also twisted the timestamp)
