What is a “coinjoin”?
Coinjoin is a collaborative transaction between multiple peers. Usually, but not necessarily, it consists of some standard output denominations that users should break their coins in to. This makes it difficult for outside parties to trace where a particular coin was sent to (as opposed to regular bitcoin transactions, where there is usually one sender and one receiver). Coinjoins can be done with non-custodial software like Wasabi Wallet, that eliminates the risk of funds disappearing or being stolen. The funds will always be in a bitcoin address that the user controls and not even developers can alter the transaction or redirect the funds. Coinjoin basicly means: “when you want to make a transaction, find someone else who also wants to make a transaction and make a joint transaction together”.
