Title: Blockchain shows 2 Transactions Post by: metinkale38 on June 30, 2016, 06:36:33 AM Hey,
i am very new to bitcoins, and tried to send about 13 mbtc, on blockchain there is another adress where the remaining money seem to go... Is that correct, or why is that? I am using Electrum... Transaction: https://blockchain.info/tx/9f01f28ffb8041810792919afd49fe0e70e86fc5d30a9dcc127549e3d8eef559 Title: Re: Blockchain shows 2 Transactions Post by: Lauda on June 30, 2016, 06:46:40 AM Is that correct, or why is that? I am using Electrum... Nothing to worry about. You don't know how Bitcoin works exactly, but I'll only summarize the important parts. Let's say that you want to send 0.2 BTC from address X which contains 0.3 BTC (1 input). You send 0.2 BTC to address Y (0.3-0.2-fees) and you have a remaining balance of ~0.1 BTC, but that balance also has 'to go somewhere'. This is what we call 'change'. The other address can either be specified by the user or it will be automatically picked by the wallet. You should see that address in Electrum (I'm not sure how it generates initial addresses though). Useful resources (I highly recommend that you read them): Input (https://en.bitcoin.it/wiki/Transaction#Input) Output (https://en.bitcoin.it/wiki/Transaction#Output) Change (https://en.bitcoin.it/wiki/Change) Title: Re: Blockchain shows 2 Transactions Post by: metinkale38 on June 30, 2016, 06:55:15 AM thank you, yes there is a "change" category under the addresses, where i can find that address...

Exactly, there's no need to worry. You can spend that balance as well if you choose to. I usually specify my own change address, but I use a different wallet (Bitcoin Core). If you have any more questions, feel free to ask here or PM me directly.Title: Re: Blockchain shows 2 Transactions Post by: Pursuer on June 30, 2016, 08:10:23 AM since you are using Electrum the default setting on it is to use a change address, you can change this in the settings. in toolbar click on tools > Preferences > {in the first tab called} Transactions > uncheck Use Change Addresses
but you will have to choose a change address to send the remainder to manually after doing this. thank you, yes there is a "change" category under the addresses, where i can find that address... in your addresses tab there is a category called change and I think you have already found that. to spend from that address you can right click on it and then if I am not mistaken there should be a send from option. edit I was right (https://github.com/kazcw/electrum/commit/5190cc03fd126cee641b3d482528a1950806ce47) you should be using version 2+ so it is has the feature. |
