What is the actual mining process?
If you find a value by increasing only the nonce value, the maximum value of int is 4.2 billion.
It will be solved in 1 second. I know that 20 million ASICs are running around the world.
If you find everything in the nonce value, what do you change then? time value? Merkle Root?

Does it include worldwide trades from the last 10 minutes?
Then, even while doing the calculations for mining, several transactions per second continue to be created around the world.
Are these included? it isn't? Then, based on when will it cut?

How is the sha256 value found in the mining program? Do we have the source code of pool's mining program?
How many times per second does asic do this program, this value finding process?
Can I embed a separate, personally customized program inside asic?
