guys: can i mining with 2 machines to 1 wallet? or every machine must have own wallet always?
There's a wallet.dat file in your BiblepayCore directory (usually ~/.biblepaycore on linux or /AppData/Roaming/BiblepayCore on windows). Just copy whatever wallet.dat file you want to use from one machine and place it in the BiblepayCore directory on the other machine.
Yeah, I havent actually done that myself yet, but I have 'one' piece of info on that. Blue said he copied his one wallet.dat file over to 10 machines, and now on his desktop he receives notifications when any machine mines a block (IE the txlist updates). So he has one consolidated wallet.
I was going to add: In POW, since coins can be received in a locked wallet, you can encrypt and lock your wallet and still receive rewards from any POW device out there mining into that single wallet.
I have some experience with this. The only thing you need to be careful with is not to "run out of keys". The wallet file has 1000 pre-generated private keys with biblepay that are used for every new address you generate. Once you used all the keys, it automatically starts generating new keys for the new addresses.
So if you start mining on a lot of PCs and they suddenly run out keys and start generating new ones, the wallet.dat you kept may not contain these new keys!
The way to mitigate this could be to start with a wallet.dat with a bigger pool of pre-generated keys (can do that with biblepay-cli keypoolrefill x where x is the amount of pre-generated keys you want. You need to be careful as you wallet.dat file can become quite big!)
