CoinJoin is a method of enhancing privacy for Bitcoin transactions by combining multiple transactions from different users into a single transaction. This makes it difficult to determine which inputs correspond to which outputs, thereby increasing the privacy of the transactions. By mixing transactions together, CoinJoin helps to break the link between the sender and the recipient, making it harder for third parties to trace the flow of Bitcoin. This process effectively obfuscates the transaction history and improves the privacy and anonymity of Bitcoin users.
