This method relies on the personal banking infrastructure so works over long distances. However generally the new higher miner fee will happen by reducing the change amount. If an output address has been reused it is very likely to be a payment output not a change output. Others have been implemented in some open source projects or services, which may use more than one technique at a time.
Payments that send exact amounts and take no change are a likely indication that the bitcoins didn't move hands. However CoinJoinXT uses a lot of block space compared the privacy gain. It has been known about since
Advances in script type privacy like Schnorr , scriptless scripts, taproot and ECDSA-2P benefit Lightning Network privacy by making its payment channel blockchain transactions appear indistinguishable from regular single-signature blockchain transactions. This is why even leaks of a small amount of information should be avoided, as they can often completely ruin privacy when combined with other leaks. At least one bitcoin company offers a satellite bitcoin service . This method relies on the personal banking infrastructure so works over long distances.
The wallet also has a feature called like-type change outputs where it generates a change address which is of the same type as the payment address; this avoids wallet fingerprinting using address types which leads to change address detection. This is why even leaks of a small amount of information should be avoided, as they can often completely ruin privacy when combined with other leaks. Without privacy malicious parties have more ability to steal your identity, snatch your large purchases off your doorstep, or impersonate businesses you transact with towards you Privacy altcoins are likely to have a more volatile price than bitcoin which increases the risk of losing part of the money due to price movements.
Avoiding address reuse is like throwing away a pseudonym after its been used. Financial privacy is essential for human dignity: If a bitcoin transaction is seen paying from cluster A to cluster B then the adversary knows that Alice has sent coins to Bob.
It works by batching up several payments into one block chain transaction. For example, it may find wallet cluster A belonging to Alice and another wallet cluster B belonging to Bob. Together this is a very strong indication that address B is owned by Mr.
On the block chain it looks like two sets of completely disconnected transactions:. Users' wallets connect to a server which coordinates the CoinJoin. Even when an attacker can identify the location of the fluff phase, it is much more difficult to identify the source of the stem. These payments can be understand as a way to intentionally do address reuse  .
