Title: Account-Address association and effect on account balance Post by: arosca on April 23, 2014, 08:01:07 PM I'm a little confused about how account balances work.
Assume the following sequence:
What is the balance of account A at this point? My understanding is that any inputs in the wallet can selected at any time for spending, including those associated with address A (and thus indirectly with account A). Will the balance of the account remain unchanged (1 BTC) in this situation?

Short answer: There are no balances in Bitcoin at the protocol level. You spend outputs of previous transactions and not balances.

I could be mistaken on this, so you should probably do some testing on testnet to be sure. If I'm right, then the default account will have a balance of -0.5 BTC (since it had 1 BTC, and you sent 1.5 BTC), and account "A" will have a balance of 1 BTC.

I am not a user of the reference client, therefore did not realize the context.

OK, I'll try this on testnet and post the results here (my testnet blockchain is still building right now :-( ) Title: Re: Account-Address association and effect on account balance Post by: arosca on April 24, 2014, 01:31:38 PM If you don't use "sendfrom" and indicate which account you are sending from, then I think it updates the default account.

Invoking sendtoaddress with a balance larger than the default account has available results in a negative balance in the default account. It turns out this is in fact documented at https://en.bitcoin.it/wiki/Accounts_explained#Accounts_and_Receiving_Addresses Quote - 'sendtoaddress' always succeeds if there are sufficient funds in the server's wallet. For example, if your wallet account balances were 100 BTC in account 'foo' and 0 BTC in the default account, then the balances after sendtoaddress 1PC9aZC4hNX2rmmrt7uHTfYAS3hRbph4UN 10.00 would be 100 in account 'foo' and -10.00 in the default account (and the overall server balance would go from 100 to 90 BTC). On the other hand, using 'sendfrom' to send from the default account with a zero balance will fail with message "Account has insufficient funds". |
