## CoinJoin Protocols

CoinJoin is a method of combining multiple payments from different users into a single transaction to obfuscate the origin of the funds. By mixing inputs and outputs, it becomes difficult for chain analysis tools to determine which input belongs to which output.

This protocol is a popular way to improve privacy on blockchains that are otherwise transparent. It is often implemented in decentralized wallets to give users control over their transaction history.

CoinJoin is a key example of how community-driven protocols can enhance privacy without relying on centralized services. It is an essential concept for understanding modern on-chain privacy techniques.
