CoinJoin

privacy
technology

A privacy technique that combines multiple users’ inputs and outputs in a single transaction.

1
definition

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.

2
limitations

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.
