which block number does the diff change on? i want to know when to switch off from the pool to solo mine with my other pcs
I'm currently developing a small info page for PXC. But i do it in my spare time, so the development performance is bad especially due to the fact that i'm moving to a new apartment at the moment. So not all the values are 100% correct, i have to improve the calculation of some values and so on. But if you want to see the remaining blocks and some other values it may help:
