Would anyone be able to point me towards some resources to fully understand what ASICs are actually doing when they are mining bitcoin?

Until now I thought that miners were working a hash backwards but I just saw something that said that is impossible.

All they do is create billions of SHA-256 hashes per second. They try to create a hash that starts with a certain number of leading zeroes. The bigger the amount of zeroes, the harder it becomes. It's basically the same as rolling dice and trying to get a sum smaller than X.

But the dice have many sides and they roll a lot of them.

And yes you can't reverse a hash, that's what makes bitcoin secure and enables proof of work. It's also what makes your passwords secure and a lot more. Hash functions are everywhere in computing and security

I good video on the security if sha-256 is this one: https://youtu.be/S9JGmA5_unY?si=7_tlRzYVwiCyGgG4
