Change addresses are an important part of most bitcoin clients.They are used to store change and to enhance a user’s privacy.Let’s see what change addresses are all about.coin stamp bitcoinA change address is an address where change from a transaction is sent.ethereum bubbleBitcoin transaction outputs can only be spent whole.bitcoin chipsetSo, if you want to send someone a portion of a bitcoin transaction output you have to spend the whole lot and send some of it back to an address you own.bitcoin level of difficultyFor example, if you have 2.00 in an address and want to send someone 1.00 you will have 1.00 change that will come back to you.buffett bitcoin not a currency

Depending on your bitcoin client this change will go to a new unused address or one of the input addresses.Bitcoin transactions are all public.You can view any and all bitcoin transactions that have ever taken place on a block explorer site like blockchain.info.This means that if someone associates your bitcoin address with you they can view all your transactions!To help you maintain some semblance of privacy two approaches are taken: So, the use of change addresses that are different from the input addresses is a good thing from a privacy point of view.It is not perfect – people can still infer that you are the owner of the change address too – but it helps.At the time of writing this is how different wallets deal with change: They can be confusing: Change addresses can be a source of confusion for new users.Bitcoin clients abstract away the business of change addresses but sites like blockchain.info allow anyone to see a specific address’s balance.Users are confused when the address they think contains all their coins in fact does not.

Usually this means that the rest of the coins are in a change address.Change addresses also show up in transactions and new users wonder who the address belongs to and whether they’ve been hacked!Address reuse gone wrong: Another downside to change addresses is how they are implemented by certain clients.blockchain.info, for example, can use an imported private key’s address as a change address.The user might think that all the funds in that private key have been spent and make that private key public with disastrous consequences!To prevent this sort of thing from happening users are advised to use a temporary wallet to import the private key and send all the coins to an address in their main wallet.Another, easier solution is to use Bitcoin Armory’s sweep private key function which can safely do this for you.Change addresses are one of those lower level aspects of bitcoin that confuse new users.But they are a necessary part of how bitcoins are spent and understanding how change works helps you avoid costly mistakes.
