CoinJoin
A privacy technique that combines multiple users’ inputs and outputs in a single transaction.
CoinJoin aggregates inputs from different users into one transaction, obscuring which outputs belong to which inputs. Variants include equal-output CoinJoin and more flexible schemes.
CoinJoin improves privacy but does not erase all history. Address reuse, timing patterns, unequal outputs, later merging coins, or exchange KYC records can reduce the anonymity set.
