Title: using old wallet
Post by: bluetie on May 13, 2011, 10:07:24 AM
my most up to date wallet is in another country (i dont have access to it at moment).
example -this wallet has 2 addresses in it - 1 address with 1000btc, second address with 500btc. 1500btc total.


i have a backup with me now about 2 months old..

for example - what if my backup does not contain the second address - it only shows 1000btc,.

if i start using my backup now.. spending all the 1000 btc.. then - next month i use original wallet - what balance will i have? will i be able to spend the 500 ok??

Yes, but it's probably not that simple (unless you know you only have two funded addresses).

Bitcoin keeps a pool of 100 unused addresses by default. Periodically on its own, and whenever you tell it to, it will "generate" a new address - pull the next one from the pool - and add a new one to the pool to replace it. This is when your backed up wallet becomes desynchronized. As long as you have not used up all 100 pooled addresses since your backup, it should contain the full balance from your regular wallet.

Any coins you spend from the backup will also be spent in your main wallet.
