Title: offline wallet address and checking balance Post by: shark255 on December 11, 2013, 11:19:01 PM If i create a wallet, get address and then close wallet for a month.
If during this time me and someone will send coins to the address, could i verify its balance via blockchain.info for example? Does the bitcoin network knows about my address balance, while my wallet is offline ?

Same thing applies to paper wallet even if the address was generated offline. You only need to be online to send coins not receive them.

Of course, if you're just not opening Bitcoin QT but still have the computer with the wallet file on it connected to the Internet, it isn't really an offline wallet.

To check the balance you can go to http://blockchain.info/address/BTC_ADDRESS_GOES_HERE (http://blockchain.info/address/BTC_ADDRESS_GOES_HERE) and yes even if you wallet is offline, the balance will show since it is still logged on the blockchain.

I want to get an idea of how address creation works. For example, how you can create an address offline yet the network knows it. Title: Re: offline wallet address and checking balance Post by: zlink on December 13, 2013, 01:18:34 AM Any address you generate offline isn't actually a part of the blockchain until the first transaction utilizing it occurs. So basically, once you send some bitcoins to your new wallet, the network becomes aware it exists and registers it into the blockchain.
