Why does the BitCore wallet have to sync on every new machine? Seems impractical. Am I missing something? Makes it hard to move money in and out of this coin.
try coinomi on Android.
The main desktop wallet has to sync, in order to have a complete copy of the blockchain.
Will the wallet sync faster on a GPU mining rig as opposed to a modern laptop? In other words do the same hashes used in mining compute the history of the chain for the wallet?
Depends on your mining rig.
Depends on the processor, OS and Hdd running the gpu mining rig.
But probably yeah, if its a mining rig compared to a laptop.
Syncing from scratch on my old as hell i5 desktop took less than 10 minutes if I remember correctly.
And about 400mb of blockchain data.
So I dont know what the actual problem you are having is.
