Topic: Difference in balance between bitcoin-qt and blockchain.info - why? Explanation? (Read 585 times)

Hello panck4beer,

thank you for your rapid answer and explanation. You mentioning of "change address" made me google and I found https://en.bitcoin.it/wiki/Change

Right at the end of that page is the paragraph "The wallet file contains the private keys for change addresses, and they can receive and send coins normally. However, the GUI in the default client does not display them in the address book."

Case solved - that is my explanation.

1JJQ7s6kLX46FjAcsHNejGADVT6GMHne8n is your change address. Bitcoin-qt might use this 0.01091471 BTC anytime in future when you send next Bitcoins, thats why it is included to your Bitcoin-qt ballance

Hello Everybody,

could somebody please help me understand ?

I have a slight difference between the total balance shown in bitcoin-qt and blockchain.info.

My balance shown in bitcoin-qt is 15.32232057 BTC, my local copy of the blockchain is up to date (block 271912).

My balance shown on blockchain info is 15.31140586 BTC
https://blockchain.info/address/1B3g1eZxAvCiHPJh7NbT1y4fJiLn2SqsUL

The difference is 0,01091471 BTC

Last night I did a transfer to my mobile of 0,1 BTC.
https://blockchain.info/de/tx/f2d6c45a72e75f99842de460c59d1ba12d3adb39aecdd9cf37fbd9de3ca9f6b4

The 0,1 BTC arrived on my mobile.

However the transaction f2d6c45a72e75f99842de460c59d1ba12d3adb39aecdd9cf37fbd9de3ca9f6b4 (which did send the 0,1 BTC to my mobile) also did send to 1JJQ7s6kLX46FjAcsHNejGADVT6GMHne8n the amount of 0.01091471 BTC. Which is exactly the difference between what my local bitcoin-qt and blockchain.info show for my wallet. 1JJQ7s6kLX46FjAcsHNejGADVT6GMHne8n is not any address of mine.

Both the bitcoin-qt which comes from the ppa https://launchpad.net/~bitcoin/+archive/bitcoin as well as the compiled 64 bits binary from https://launchpad.net/~bitcoin/+archive/bitcoin show the balance of 15.32232057 BTC ( i.e the slightly higher amount ). I verified the sha256 hash for the bitcoin-qt from sourceforge.

I have set zero transaction fees in bitcoin-qt.

bitcoin-qt version v0.8.5.0-gef14a26-beta in the ppa version of bitcoin-qt. Version v0.8.5-beta of bitcoin-qt from sourceforge.

So why ? I do not understand the difference and not understanding makes be feel uneasy.

Thanks

Max.
