Topic: want a wallet for multiple address ?? (Read 679 times)

Tell your friend to check the bitcoin api. Maybe he can develop what he is looking for.

Walletexplorer is actually one of the lesser advanced blockchain analytical tools available.

Even if you never reuse addresses, and none of your trading partners reuse addresses, it is still possible to link some of your addresses together. For example, if you send BTC to one person, and send the change to one change address, then send BTC to a second person, sending the change to a second change address, then subsequently send BTC to a third person using inputs from both of these change addresses, then one could reasonably determine that both of the change addresses belong to you, and if more then one input was used for each of the previous transactions, that the addresses from each of the above transactions all belong to you.

In order to avoid the above issue, you can heavily track where the BTC contained in each of your addresses came from, including change addresses.

You can further avoid this by avoiding using change addresses altogether by sending whole amounts contained in inputs to your trading partner in each transaction, although this will somewhat limit you as you may not need to send exact amounts to the person you are trading with. If you frequently trade with someone (and sufficiently trust them), then you could send an extra 0.05 to your trading partner instead of sending that amount to a change address, and you both could stipulate that the 0.05 will be applied to the next time you need to send them BTC.

CJ transactions can be traced with fairly decent amounts of accuracy (source -- I had thought there were more recent articles about this issue, but am unable to find them currently).

I would like to ask too about wallets, it is inclined with multiple accounts. What if i have multiple accounts is it ok to have it in the same address? I've read about multiple accounts in the rules and multiple sales. Please correct me if it is the same.

Address reuse would certainly result in the connection of several addresses being made.

Most wallets eliminate this by allowing users to use separate addresses to receive each transactions. For example, Electrum gives the user addresses to receive the Bitcoin and after that, the coin that is not sent to the address you specify is sent to a change address. Electrum also puts the address under "Used" once it has at least 1 transaction.

You can choose the inputs to ensure that the address are not linked together by spending them all in the same transaction.

That being said, Electrum allows users to create different wallets to have their addresses in.

Edit: achow was faster again

The only way that connections can be found by multiple addresses is if they are being spent from in the same transaction. There is no such wallet that only spends from one address at a time as that presents a major usability issue. Rather you would have to manually choose which inputs you want to spend from in order to keep the addresses separate.

Alternatively you can use Joinmarket to do your transactions. Joinmarket uses CoinJoin which means that your transaction is combined with inputs and outputs of other people such that an outside observer does not know which inputs and outputs are yours. It greatly enhances privacy, but can be a little hard to use.

Actually one friend ( who is programmer ) asked me for a wallet which can be use by us to make  multiple adress but no one can found connection between each other ( I don't mean that no one can trace adress to see payment made at which which adress ) .
 
Since I suggested to my friend but he said that " I want only that wallet that can create multiple adress and not track the connection between them through other websites like walletexploer " .
