CoinJoin is a method used to enhance privacy in transactions. It allows multiple users to combine their coins into a single transaction, obscuring the paths of the individual coins involved. By pooling transactions together, it becomes difficult to trace which coin belongs to whom.In practice, participants create a joint transaction that sends the combined funds to new addresses controlled by each person in the group. This mixing of coins makes it harder for external observers to link specific transactions to individual wallets.Developed by Gregory Maxwell in 2013, CoinJoin emphasizes the importance of anonymity in a public ledger system. It has been implemented in various wallets and platforms, allowing users to maintain greater privacy while transacting. While it doesn’t guarantee complete anonymity, CoinJoin offers a significant improvement over standard transactions, making it a popular choice for those valuing privacy.
