Coinjoin
Coinjoin is a trustless protocol for mixing UTXOs from multiple owners in order to make it difficult for outside parties to use the block chain’s transaction history to determine who owns which coin.
Named after a 2013 proposal by Gregory Maxwell, several independent implementations have provided support for various forms of coinjoin.
