&lt;div&gt;[[File:SharedCoin.png|300px|thumb|right|What a usual Shared Coin transaction looks like]]&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Shared Coin&#039;&#039;&#039; provides privacy for users&#039; [[Bitcoin transaction|transactions]] by combining their transactions with other people&#039;s.&lt;br /&gt;
&lt;br /&gt;
Shared Coin uses a technique similar to CoinJoin to make transactions private without needing to trust the Shared Coin service. A user&#039;s coins never leave their control and therefore it is impossible for them to be [[Bitcoin Vulnerability|stolen or confiscated]].&lt;br /&gt;
&lt;br /&gt;
== FAQ ==&lt;br /&gt;
&lt;br /&gt;
; How does it work?&lt;br /&gt;
&lt;br /&gt;
Shared Coin is a method of making transactions which requires less trust in the service. Shared Coin is based on the CoinJoin concept which acts as a meeting point for multiple people to join together in a single transaction. Having multiple people in a transaction improves privacy by making transactions more difficult to analyse. The important distinction between traditional mixing services is the server cannot confiscate or steal user&#039;s coins.&lt;br /&gt;
&lt;br /&gt;
; What logs are kept?&lt;br /&gt;
&lt;br /&gt;
The server does not need to keep any logs and transactions are only kept in memory for a short time. However if the server was compromised or under subpoena it could be force to keep logs. If this were to happen although you haven&#039;t gained any privacy you haven&#039;t lost any either.&lt;br /&gt;
&lt;br /&gt;
; Are there any fees for shared transactions?&lt;br /&gt;
&lt;br /&gt;
Shared Coin is a free service however a bitcoin network fee of 0.0005 BTC is required.&lt;br /&gt;
&lt;br /&gt;
; How long do shared transactions take?&lt;br /&gt;
&lt;br /&gt;
Between 30 seconds to 5 minutes depending on the number of iterations.&lt;br /&gt;
&lt;br /&gt;
; Is there a maximum transaction size?&lt;br /&gt;
&lt;br /&gt;
The maximum transaction size is 50 BTC.&lt;br /&gt;
&lt;br /&gt;
The user should also remember that Shared Coin can never completely [[Anonymity|sever the link]] between the input and destination address, there will always be a connection between them, it is just more difficult to analyse.&lt;br /&gt;
