Title: Can I use the same wallet on 2 machines?
Post by: Cablesaurus on May 26, 2011, 08:19:13 AM
Wondering if it's possible to use the same wallet from 2 different bitcoin-setup machines? For redundancy? Would they synch? Curious.

You could probably setup dropbox and have your wallet in that, then run the client with -datadir <dropboxdir>\wallet or something like that, then everytime your wallet changes it would sync, AND you have copy online, might want to TC encrypt it first though. :)

Please donate ;)

They will NOT stay in sync; when you receive payments, they will then generate new addresses which will be different from each other. This is, as you can imagine, a recipe for losing your bitcoins forever.

aren't new addresses generated only when you send payments? It makes no sense generating new ones when receiving them...

No, they're generated when you receive payments to an address (that hasn't been paid before) - precisely BECAUSE you received a payment. It's to encourage you to use new addresses for each transaction.

but how would that work? If i have an encrypted wallet somewhere only for receiving donations, how could new address be generated without the software? I know they're generated when sending coins, as some of them are sent back to a new address...

The new address will be generated the next time you start up bitcoin.

OK fair enough. But those addresses would not have any coins attached to them, so they're not important (one wouldn't lose coins even if those addresses are lost)?

Anyway, thanks for clearing that up for me :)

Sure, but invariably you'll pick one of those addresses to give to someone to pay you.

Yes, the Dropbox sync method would work, but then you have the problem of someone swiping your wallet.dat out of Dropbox.

Yes, that's why it's in a TC volume.

And THAT only works if you can guarantee that only one client will access it at a time. Otherwise you run the risk of file corruption.
