I just downloaded pywallet and did "pywallet.py --dumpwallet".  It was a real eye-opener.

I don't think I have any change addresses. In my case, this address is my wallet, my bitcoin program has only one address in it.

When I click the export button, I still have only one address displayed, and it's the abovementioned one.

If it is the "satoshi" (reference) client and you ever sent coins to any one (even yourself) even once you have a change address.  That is how Bitcoin works.

OK in bitcoin-qt I have 4 addresses.  2 of them have no transactions and 2 do.  My balance according to bitcoin-qt is 25.41034921 BTC.

According to blockchain.info, address #1 has 24.99248018 BTC and address #2 has 0.12402675 BTC, totalling 25.11650693.
I double checked the 2 empty addresses against blockchain.info and they're both 0 BTC with no transactions.

I appear to have 0.29384228 BTC more than I should.

Short of exhaustively going through all 685 transactions and reconciling them against blockchain.info, any suggestions?

you may (almost certainly) have change address which don't show in bitcoin-qt client.
You can do a dump of your wallet to see all addresses including change addresses.

Same for me.  My wallet and blockchain.info differ by a small amount.  I have only 1 address specified in my wallet.

No change addresses?
I probably spoke too soon.  I'll check it when I get home and report back.

An address isn't a wallet.  The unspent outputs for that address are 0.0007.  You have unspent outputs on other addresses.

Technically to the Bitcoin protocol there is no such thing as a wallet.  Your client is just adding up the current value of all addresses in your wallet.dat file and showing you the balance.

If you exported all the addresses of your wallet and looked all them up manually on blockchain.info and added up the balances it should match what your client displays.

As it says in the title,

https://blockchain.info/address/1M5oZcUzHGT3mzNeA73opLUdSPSpKL5NE3
states that the wallet has 0.0007 BTC, while currently I am the proud owner of about 0.202 BTC Smiley

Any comments?
