Coinjoining is a method for Bitcoin users to improve their privacy by combining their transactions with those of other users. This way, it is impossible to tell which inputs come from which person — or which outputs belong to which person. It is described in detail on bitcointalk.org.
Before they can merge transactions, the parties first need to find each other. We leave this to you: find some friends familiar with raw transactions, start a coinjoin session, and pass them the link.
The joiner is also available as a Tor hidden service. You can access it at either of these URLs.
