This question is for the developers. I know that you need 1 confirmation for small amount and up to six for larger amount, but where in the source code this is programmed? I mean where in the source code the pending transactions are moved from pending to available (condirmation = confirmation +1)
In my case, I have the transaction stuck in my altcoin wallet, but the transactions never get confirmed, they are staying in pending stage. I want to know where is the code and understand how the confirmation process is done in programming.

There must be some kind of validation (but I do not find that in validation.cpp or in mining.cpp). The problem I have is that the transactions are not confirmed regardless of what fees I apply, and there is no warning or error messages, so I have no choice than studying how the confirmation is programmed to find what is incompatible with my modifications.


Thanks
